Alabama Pest Management Handbook for 2013

The Alabama Pest Management Handbook—Volume II contains recommendations for houses, buildings, and grounds; commercial trees and ornamental crops; commercial horticultural crops; and homeowner lawns and ornamental and garden crops. It was compiled by both current and former Extension entomologists, plant pathologists, weed scientists, and a pesticide education specialist and provides the most recent information possible on the selection, rates, application, and safe and proper use of pesticides. A directory of the specialists who authored sections in this publication is included. Since the status of pesticides is constantly changing, some that are currently listed in this volume of the Alabama Pest Management Handbook may no longer be legal. Also, some recently labeled pesticides may not yet be included in this volume. For these reasons, anyone preparing to use a pesticide should always consult the current pesticide label on the container before application. Chemicals are listed both by common names (lowercase letters) and by trade names (all capital letters). Some chemicals are available only under trade names and, therefore, their common names may be omitted because of space restrictions. The presence or absence of any particular trade name in no way indicates endorsement or discrimination on the part of the Alabama Cooperative Extension System. Recommended uses of pesticides are based on research, field trials, demonstrations, and experience. Because of variations in environmental conditions and methods of application, these recommendations do not assure that your results will always be the same as those obtained in research. The label on every pesticide container presents information that is essential to safe and proper use, handling, and storage of the pesticide. Users are responsible for adhering to label information and should always review it thoroughly before applying the pesticide. Applying rates that exceed the recommendations or shortening the waiting period from application to harvest or grazing can cause excessive residues that are illegal according to state and federal regulations. See the table at the end of this introduction for abbreviations used throughout the Alabama Pest Management Handbook.

WORKER PROTECTION STANDARD The U.S. EPA Worker Protection Standard (WPS) protects employees on farms, forests, nurseries, and greenhouses from occupational exposure to agricultural pesticides. The regulation covers two types of employees: · Pesticide handlers—those who mix, load, or apply agricultural pesticides; clean or repair pesticide application equipment; or assist with the application of pesticides in any way. · Agricultural workers—those who perform tasks related to the cultivation and harvesting of plants on farms or in greenhouses, nurseries, or forests. Workers include anyone employed for any type of compensation (included self-employed) doing tasks (such as carrying nursery stock, repotting plants, or watering) related to the production of agricultural plants on an agricultural establishment. Workers do not include such employes as office employees, truck drivers, mechanics, and any other worker not engaged in worker or handler activities. In addition there are some WPS requirements that apply to all persons and some that apply to anyone who handles

pesticide application equipment or cleans or launders pesticidecontaminated personal protective equipment. The WPS requires agricultural employers to provide four basic protections for their employees. 1. Employees must receive pesticide safety training. 2. Information concerning pesticides applied in the work area must be posted in a central location. 3. Employees must be excluded from treated areas or provided proper training and safety equipment if they may be exposed to pesticides. 4. Employers must supply decontamination sites (soap, water, etc.) for workers. Emergency assistance must be available for any employee injured by pesticides. Refer to the EPA Worker Protection Standard for Agricultural Pesticides—How to Comply for details. (This publication is available at the following website: www.epa.gov/pesticides/safety). Additional information is available from the Alabama Department of Agriculture & Industries (334-240-7239) or Auburn University Cooperative Extension System (334-8448832).

SAFE USE, HANDLING, AND STORAGE OF PESTICIDES Most pesticides are synthesized chemicals which have proven effective, useful, and safe if used according to label instructions. Many pesticides, however, are poisonous and may be a hazard to humans, animals, plants, and the environment if they are not handled and used properly. Certain procedures are required when dealing with pesticides. They are: • Identify the pest. • Determine the correct pesticide. • Apply the pesticide properly. • Store the pesticide safely. • Dispose of the empty containers safely. The following suggestions for using, handling, and storing pesticides will minimize the likelihood of injury to man, animals, plants, and the environment. General Precautions 1. Always read all precautionary labeling directions before using pesticides and follow them exactly. Notice warnings and cautions before opening the containers. Read them each time, no matter how often you use a pesticide or how familiar you are with the directions. Apply material only in the amounts and at the times specified. 2. Keep pesticides out of the reach of children, pets, irresponsible persons, and livestock. They should be stored outside the house, away from food and feed, and under lock and key. 3. Store pesticides in their original containers with a legible label intact. Keep the container tightly closed. 4. Never smoke or eat while applying pesticides. 5. Avoid inhaling sprays or dusts. When directed on the label, wear protective clothing and an approved mask.

6. Should pesticides be accidentally spilled on the skin or clothing, remove contaminated clothing immediately and thoroughly wash contaminated skin for at least 15 minutes. 7. Bathe and change to clean clothing after spraying or dusting. If it is not possible to bathe, wash your hands and face thoroughly and change clothes. Also, wear clean clothing each day. 8. Cover all food and water containers when treating around livestock or pet areas. Be careful not to contaminate fish ponds, streams, or lakes. 9. Never reuse pesticide containers. 10. Dispose of all empty containers after rendering them useless, so that they will not become a hazard to humans, animals, valuable plants, or wildlife. Disposal regulations need to be determined before carrying a load of containers to a landfill. 11. Observe directions and follow recommendations in order to keep the residue on edible portions of plants within the limits permitted by law. 12. If symptoms of illness occur during or shortly after dusting or spraying, call a physician or get the patient to a hospital immediately. Also, take a label from the pesticide container with you. 13. Do not use your mouth to siphon liquids from containers or to blow out clogged lines, nozzles, etc. 14. Do not spray with leaking hoses or connections. 15. Do not work in the drift of a spray or dust. 16. Confine a pesticide to the property being treated. Avoid drift to adjacent properties by stopping treatment if weather conditions become unfavorable. 17. Notify all nearby beekeepers before applying any insecticide.


18. If laborers are working in crops with heavy foliage, such as cotton, tomatoes, peaches, or tobacco, that has been treated with highly toxic compounds, be sure the restricted entry interval (REI) between treatment and entrance into the treated area is observed. REIs are listed on the pesticide label. Workers in such fields should follow the same precautions as given for the applicators in regard to changing clothes and wearing protective clothing, eating or smoking, and bathing. If workers become ill while working under these conditions, take them to the emergency room immediately. Be sure to take the pesticide label. Precautions for Using Highly Toxic Chemicals Use extreme caution when handling concentrates of any restricted use pesticides or other highly toxic pesticides. When using these materials, observe the following rules: 1. Wear liquid-proof gloves. The pesticide label will tell you what gloves to use. Remember, however, that some fumigants are readily absorbed by neoprene. 2. When mixing and applying these materials, wear a cartridge respirator approved for the specific pesticide and also wear protective clothing such as a long-sleeved shirt and a washable rain hat. Specific types of cartridges and canisters protect against specific chemical gases and vapors. Be sure you choose one that is made for the pesticide you are using. Use only those that are approved by the National Institute for Occupational Safety and Health (NIOSH) or by the Mining Administration (MESA). This information can be found on the label. The respirator must fit your face well. Read the manufacturer’s instructions on the use and care of any respirator and its parts before you use it. When applying pesticides, if you have trouble breathing or if you smell the pesticides, change the respirator’s filters, cartridges, and canisters. Remove and discard the filters, cartridges, and canisters after use. Then wash the face piece with detergent and water, rinse it, and dry it with a clean cloth. Store it in a clean, dry place away from pesticides. 3. Start each day with clean clothing. Change garments when they become wet with spray. Bathe before returning to work. Take a thorough bath as soon as the work day is finished. 4. Have soap, clean water, and clean clothes on hand in the field in case of an accidental contamination. 5. Aircraft pilots should not assist in mixing or loading the chemicals into the plane. 6. Avoid overhead or into-the-wind application. Precautions For Protecting Water Quality Protecting the quality of our water is one of the Environmental Protection Agency’s objectives for an overall cleaner environment. Pesticides have been identified as a potential source of water contamination. The EPA has begun a review of pesticide registrations to determine which pesticides pose undue risks to water supplies. A nationwide water-well pesticide contamination survey is underway to identify potential problems. Users should be aware of the surface-loss and leaching potentials of pesticides and of practices that could contribute to ground water contamination. The following suggestions can help prevent water contamination.

1. Triple rinse your empty pesticide container and pour the rinse water into a spray tank. Then, apply it to the area or site being treated. 2. Prevent any back-siphoning of the chemical when filling a spray tank by leaving an air-gap between the high water level and the end of the water hose or by adding the pesticide after the desired water level has been reached in the spray tank. 3. Catch the rinse water from the spray tank instead of emptying it onto the ground in one area. Then, spray it over the area being treated. 4. Protect the well head from surface water entering the top of the well. Use a concrete apron around the well head with an appropriate cover. 5. Determine if the pesticide you are using may create a problem with leaching. Your county Extension agent can provide you with this information. 6. Calibrate your application equipment to ensure that the correct rate is being applied. 7. Do not fill spray tanks from streams, drinking water tanks, or farm ponds. Pesticide label directions may specify a distance from the well head to fill a spray tank or for handling rinsate. Endangered Species The Endangered Species Protection Act of 1973 requires all federal agencies to help protect the environment—specifically, the habitat and species of animals and plants that are almost extinct because of human encroachment or changes in the environment. A specific pesticide label program was initiated by EPA to identify sites and chemicals that could endanger certain species and their habitat. The final federal regulations have been delayed, but interim county maps are available on the world-wide web (www.acesag.auburn.edu/department/ent/). These maps show areas where endangered species have been identified. Chronic Toxicity Toxic doses of chemicals can cause either chronic or acute health effects. An acute effect usually follows a large dose. However, if the chemical is highly toxic, a very small amount can cause symptoms of poisoning. Labels of highly and moderately toxic pesticides list poisoning symptoms. Generally, chronic toxicity occurs periodically after longterm exposure. Symptoms are difficult to describe because specific data is often not available. Most long-term effect studies have failed to identify specific pesticides and their role in chronic toxic symptoms. Pesticide users who experience unusual sinus problems, watery eyes, or some type of skin condition that does not clear up should seek medical attention. Disposal Excess Pesticides The EPA recommends ways to dispose of excess pesticides. Consult local authorities for procedures in your area. If you have excess organic pesticides, use them as directed on the label or store the pesticides until you can use them. If you have

Safety: Alabama Pest Management Handbook for 2013 • 5

any questions concerning the disposal of excess pesticides, contact: Mr. Gerald Hardy Alabama Department of Environmental Management Land Division Chief 1751 Congressman W. L. Dickinson Drive Montgomery, AL 36130 Phone: 334-271-7730 Mr. Tony Cofer Program Director–Pesticide Management P.O. Box 3336 Montgomery, AL 36109-0336 Phone: 334-240-7242 Containers To prepare a container for disposal: 1. Empty the container into the spray tank. Then, let it drain for an additional 30 seconds. 2. Fill it one-fourth full of water. 3. Replace the lid and gently shake the container. Turn the container upside-down to rinse all of the side surfaces. 4. Carefully drain the rinse water from the container into the tank. Let the container drain for 30 seconds. 5. Repeat steps 2 through 4 at least two or more times for a total of at least three rinses. Remember to empty all rinse solutions into the spray tank. The EPA recommendations divide containers into three groups and tell you how to dispose of each kind. Group I Containers. These are containers which will burn. They hold organic or metallic organic pesticides but not an organic mercury, lead, cadmium, or arsenic compound. Dispose of them in one of the following ways: • Burn them in an approved pesticide incinerator. • Bury them in a specially designated landfill. • Burn small numbers of them as directed by state and local regulations. Air pollution boards or other designated regulations control certain burning conditions.

Group II Containers. These are containers which will not burn. They hold organic or metallic organic pesticides but not organic mercury, lead, cadmium, or arsenic compounds. First, rinse the containers three times. Then, dispose of them in one of the following ways: • Send or take the rinsed containers to a place that can recycle them as scrap metal or dispose of them for you. • Many large containers in good shape can be reused by your supplier. Return them to the pesticide manufacturer, formulator, or drum reconditioner. • All rinsed containers may be crushed and buried in a sanitary landfill. Follow state and local standards. • Bury rinsed containers in a field or property that you own, if you have obtained a certificate of exception from your county or municipal health department. To get a certificate of exception, file an application and plan for disposal with your county health officer. The officer must investigate the plan and site before approval and certification. If the containers have not been triple rinsed, they can be buried only in a specially designated landfill. Group III Containers. These include containers which hold organic mercury, lead, cadmium, arsenic, or inorganic pesticides. Dispose of them in one of the following ways: • Rinse them three times and dispose of them in a sanitary landfill. • If they are not rinsed, bury them only in a specially designated landfill.

Submitting Samples IPM-1294


SUBMITTING SAMPLES FOR DIAGNOSIS, ANALYSIS, AND IDENTIFICATION The Alabama Cooperative Extension System supports two plant diagnostic laboratories. One is at Auburn University; the other is located in Birmingham at the Birmingham Botanical Gardens. The Plant Diagnostic Laboratory at Auburn University provides three services: plant problem diagnosis, soil nematode analysis, and insect identification. Plant problems sent to the lab include diseases, nematode injury, insect damage, chemical damage, environmental stress, horticultural and agronomic problems, or wildlife damage. Plant samples at the Auburn University Plant Diagnostic Lab are initially examined by a plant pathologist. Some samples may then be referred to Extension specialists in entomology, agronomy, horticulture, or wildlife. In addition to plant problem diagnosis, soil nematode analysis, and insect identification, plants are also received for identification. These plants are referred to agronomists and horticulturists who typically respond to the inquiries. Weeds for identification should be sent directly to Extension weed scientists. Address them to Extension Weed Scientist, 109 Exension Hall, Auburn University, AL 36849-5633. Give the name of the crop infested. The Plant Diagnostic Laboratory at the C. Beaty Hanna Horticulture and Environmental Center at the Birmingham Botanical Gardens in Birmingham is available to provide plant disease diagnoses to residents of the greater Birmingham area, including Jefferson, Tuscaloosa, Walker, Blount, St. Clair, Shelby, and Bibb counties. It is extremely important that samples and specimens be collected and packaged correctly for diagnosis and analysis. For example: • Soil for nematode analysis must not be dried out or too wet. • Nematodes that have been subjected to extreme temperatures or moisture will die and are not suitable for diagnosis. • Dried or decayed samples are not satisfactory for diagnostic purposes. • Plant, soil, and insect samples must be accompanied by the proper information for adequate diagnosis, analysis, and/or identification.

The information in this section explains the proper collecting and packaging techniques needed for an accurate diagnosis. Read it carefully. Then, mail or bring samples and specimens to: Plant Diagnostic Lab ALFA Agricultural Services & Research Building 961 South Donahue Drive Auburn University, AL 36849-5624. If you reside in Jefferson or adjoining counties, you may bring or mail samples to: Plant Diagnostic Lab C.

PLANTS FOR DISEASE/PROBLEM DIAGNOSIS James Jacobi, Extension Plant Pathologist, Entomology and Plant Pathology, and Kassie Conner, Extension Plant Pathologist, Entomology and Plant Pathology For an accurate diagnosis of a plant problem, the lab must receive the following: 1. Fresh plant material that is representative of the total problem. 2. Enough plant material for two to three specialists to examine and/or for two to three testing procedures. 3. Information that accurately describes the history of the plant and problem development. Remember that diagnoses are often based on the visible plant symptoms, associated microscopic structures or other test results, and the information included. If the plant sample is not representative of the actual problem and the information is inaccurate or misleading, the conclusions and diagnoses made in the lab may not be appropriate for the actual problem. The diagnosis can be based only on the sample and information sent to the lab. Collecting Plant Specimens 1. The specimen must be representative of the problem. If possible, collect the plants intact, including roots, because the above-ground plant symptoms could be caused by a root problem. Dig out—don’t pull up—plants. Gently shake off soil but do not wash roots. Wrap roots in a plastic bag to prevent contact of soil with foliage. If you can’t collect intact plants, include the plant parts that show damage. If possible, collect several plants or plant parts, such as fruits, nuts, twigs, and leaves, representing different stages of the disease or problem. Do not collect dead plants. 2. After collecting the sample, gently shake off or blot any water droplets that may be present. Wet samples will decay rapidly. Place the sample in a plastic bag immediately and close the bag securely. Do not include any wet or damp paper towels with the samples. If samples must be kept for a time before packaging and mailing, keep them cool. 3. If you suspect a soil problem, send 1 or 2 pints of soil from the affected area and 1 or 2 pints of soil from the nonaffected healthy area so that pH, total soluble salt level, and the possibility of nematodes can be checked. Package the soil in a sealed plastic bag. 4. If you suspect a soil nutrition problem, you may send a soil sample directly to the Soil Test Lab. Collect 1 pint of soil from the suspect area. Directions, packages, and forms are available at your county Extension office. Package and mail samples to Soil Testing Laboratory, ALFA Agricultural Services and Research Building, 961 South Donahue Drive, Auburn University, AL 36849-5411. The current charge of $7 for a routine soil analysis is subject to change. Call 334-844-3958 or check with the lab at http://www.aces. edu/anr/soillab/ for more information on soil testing. 5. Check with your county Extension office if you have questions, or check the Plant Diagnostic Laboratories’ websites at http://www.aces.edu/dept/plantdiagnosticlab/ for the Auburn lab and http://www.aces.edu/plantlabbham/ for the Birmingham lab. Or, you may contact the labs by phone at 334844-5507 or 5508 for the Auburn lab or 205-879-6964 (ext. 19) for the Birmingham lab.

Packaging and Mailing Plant Samples 1. Pack the sample well in a sturdy container to prevent crushing. Padded envelopes or boxes are best. 2. Provide as much information as possible. Use the diagnostic questionnaire, Form ANR-89 or Form ANR-89B. These forms (ANR-89 and ANR-89B) are available from the Auburn and Birmingham websites, respectively. They may also be obtained from your county Extension office. If more space is needed, use additional sheets of paper. The more information provided with the sample, the more accurate the diagnosis and control recommendations will be. 3. If samples must be held for a time before mailing, keep them cool. 4. When sending in a soil sample with the plant sample, always place the soil in a separate plastic bag. Always seal the soil sample bag. 5. The service charge for plant disease/problem diagnosis depends upon the diagnostic procedures needed. The charge is usually $15 for residential and $20 for commercial locations, and a minimum of $30 for advanced molecular testing. Advanced molecular testing is done only after specific discussion with the client. The diagnostic response, recommendations, and an invoice will be mailed directly to you, usually within 7 to 10 days from the time the sample is received. Checks or money orders should be made payable to the Plant Diagnostic Lab. 6. Samples sent from out of state must be double sealed in heavy plastic bags and placed in a sturdy container before shipping. The charge for out-of-state samples is $30 for residential and $40 for commercial, which is double instate fees. Special Handling Techniques for Certain Types of Plant Samples 1. Lawn or Turf Specimens: Take the sample from the edge of the affected area. Provide both diseased and healthy plant material. Samples should be approximately 8 to 10 inches square by 3 inches deep. Package samples in a sealed plastic bag. Do not wrap sample in newspaper. 2. Fleshy Fruits and Vegetables (apples, peaches, grapes, tomatoes, cabbage, Brussels sprouts, broccoli, etc.): Wrap sample in several layers of dry newspaper. Do not place sample in a plastic bag. Do not include wet or damp towels or paper. 3. Woody Trees or Shrubs With Cankers or Galls: Cut three to five branches with cankers or galls. Make cuts several inches beyond the margin of the damage. Be sure to include some living wood. 4. Woody Shrubs or Small Trees With Wilted Foliage, Dieback, and/or Poor Growth: Include three to five branches (12 to 16 inches long) showing foliage symptoms, a root sample large enough to fill a quart- or half-gallon-size bag, including larger roots along with feeder roots, and 1 to 2 pints of soil. Package branches, roots, and soil in separate plastic bags. Also, include a soil sample from similar shrubs or trees that appear healthy. 5. Large Woody Trees With Wilted and/or Dying Foliage and Branches: Collect branch segments (12 to 16 inches long)

Submitting Samples: Alabama Pest Management Handbook for 2013 • 3

that have wilted, dying, or scorched foliage. Be sure the branch segments have some living wood. Look for branches that show any dark brown, black, tan, or greenish streaks just under the bark (in the vascular tissue). Branch segments should be 0.5 inch or more in diameter. Place four to five branch segments in a plastic bag. Be sure to keep the samples cool. A sample of roots and soil may be needed. See number 4 above for details 6. Small Herbaceous Garden Plants or Field Crops: Collect 10 to 12 whole plants (4 to 12 inches tall) that show symptoms. For plants less than 4 inches tall, collect approximately 20 plants. For seedlings, collect at least 20 to 30 plants. Carefully dig up whole plants and place them in a plastic bag. In a separate plastic bag, send 1 to 2 pints of soil.

7. Mature Herbaceous Garden Plants or Field Crops: Dig up two or more whole plants, including the root systems. If the plants are large, cut them into three or more sections so that they may be enclosed in a plastic bag. Also, send 1 to 2 pints of soil from the garden in a separate plastic bag. 8. Mushrooms: Collect several specimens if possible. Include mushrooms at different stages of growth. Wrap each specimen gently in waxed paper or several layers of newspaper. Package mushrooms in a crush-proof box with a lightweight filler material such as styrofoam chips to prevent damage during transit. For submission forms, contact your county Extension office or http://www.aces.edu/dept/plantdiagnosticlab/ or http://www. aces.edu/plantlabbham/.

INSECT SPECIMENS FOR IDENTIFICATION AND ANALYSIS Charles Ray, Research Fellow, Entomology and Plant Pathology Collecting for Identification The identification of an insect is the first step in determining whether it should be controlled and what control measures should be used. Auburn University provides identification assistance when it is needed. A good insect specimen and supporting information are essential for pests to be correctly identified. County Extension offices furnish specific information on what is necessary for collecting, preserving, and shipping specimens and the supporting information that should be included. Preserving and Packaging Most insects should be preserved immediately after collection. Include several specimens, if possible. Most can be killed and preserved in glass or plastic vials in 70 percent isopropyl (rubbing) alcohol. Do not send insects in water.

Containers must be leak proof. It is advisable to wrap the cap with electrical tape to prevent any leakage. Spiders and soft-bodied insects such as caterpillars, grubs, and maggots should be placed into hot (nearly boiling temperature) water for a minute and allowed to cool slightly before being placed in alcohol. This ensures that some important microscopic features remain visible. Even dead specimens should be so treated. Large, fragile insects such as butterflies and moths should be killed in a kill jar or freezer and stored in a crush-proof container without alcohol. Tissue paper gently placed around the specimens will keep them from becoming damaged in the mail. Very fragile insects, such as mites, thrips, aphids, and scales, should be packaged and sent in the same manner as diseased plants. These insects are easily damaged by removing


them from the plant; also, their appearance on the plant as well as damage symptoms may be important for identification. If possible, send small caterpillars, grubs, and maggots alive in a plastic bag with some of the host material. It may be necessary to rear some of these to the adult stage for positive identification. Place the plastic bag in a container that will not be crushed in the mail. Finally, if at all possible, ticks found on humans or pets should be sent in alive. Ticks can be kept alive for several days in a small, loosely capped container with a slightly moistened paper towel or a cotton swab moistened with one drop of water. Include the following information for each sample: 1. Name of collector. 2. County and nearest town.

3. Date collected. 4. Where found, such as on a host plant, animal, or location in a building. If the host was a plant or animal, give its stage of growth. If the specimen was found on a person, provide the person’s name and phone number. 5. Degree of infestation (heavy, medium, light) and type of damage. 6. Insecticide used for control and results, if known. 7. Service charges for insect identification: • Commercial/Industrial: $20.

SAMPLE PLANTS FOR WEED IDENTIFICATION John W. Everest, Professor Emeritus, and Michael G. Patterson, Visiting Professor, Crop, Soil and Environmental Sciences To identify weeds, a complete plant or a specimen containing leaves, stem, roots, and flowers or fruit is absolutely necessary. The success of each identification depends to a large degree on the condition of the plant material at the time of identification. Decomposed, dry, or incomplete plant specimens make identification difficult, if not impossible. Adequate specimens with flowers or fruit usually produce positive results. The following points will help in the identification process and in making control recommendations. Collecting Weed Specimens 1. Collect and submit intact plants with roots, if possible. If the weed is small, collect several plants. 2. If the weed has flowers and/or fruit present, collect plants which have these parts. 3. If the weed is too large to submit, send samples of the roots, stem, leaves, flowers, and fruit. Please indicate the size of the plant. 4. In some plants, especially grasses, it is necessary to have the flowers or seedheads. Otherwise, only a general identification can be made.

Packaging and Mailing Specimens 1. Do not let the plants lie around for several days before packaging. 2. Place the plant(s) or plant parts in a plastic bag. A dry paper towel may be placed in the bag to prevent crushing the sample. Do not add water. 3. Pack sealed plastic bag in a shipping container which is sturdy and large enough to prevent crushing the specimen during transit. 4. Label the package WEED ID and mail to 109 Extension Hall, Auburn University, Auburn, AL 36849-5633. Additional Information The following should be included with each specimen: 1. Location or crop where weed was collected. For example: roadside, forest area, cotton field, edge of pond, St. Augustine lawn, fescue pasture, etc. 2. Any other pertinent information that might influence the control recommendation, such as location and proximity of desirable plants in the area; whether the pond is used for swimming, fishing, or irrigation; size and degree of weed problem; etc.

SAMPLES FOR PESTICIDE RESIDUE ANALYSIS Sonja B. Thomas, Coordinator - Pesticide Safety Education Program The Alabama Department of Agriculture and Industries operates a state laboratory for special pesticide residue problems related to raw agricultural products and the environment. Samples that originate because of a second party or conflict between landowners or between pesticide applicator and/or landowner(s) should be official samples taken by an Alabama Department of Agriculture and Industries inspector. Call 334-240-7239 with specific details about why an analysis is needed. Arrangements will be made concerning the taking of an official sample. Water Samples Private water wells which are contaminated and possibly endangering human health can be handled by the Alabama Department of Environmental Management, Groundwater Section, in Montgomery, Alabama; telephone 334-270-5655. The director of this section should be contacted because an inspector will be needed to obtain an official sample. DO NOT mail or transport samples to this laboratory.

When the owner of a private well suspects contamination by a commercial pest control company, he/she should contact Tony Cofer, 334-240-7237, for an official sample to be taken by a state agricultural inspector. Private laboratories are also available for residue analysis. The cost varies depending on the product and tests needed. These labs are located in Alabama’s larger cities. Soil and Plant Samples Pesticide residue analysis is difficult for several pesticides because of their chemical nature and the special equipment needed by the laboratory. An adequate sample is a must. For residue determination, contact Tony Cofer, 334-240-7237, for an official sample to be taken. All additional information will be collected by the state agricultural inspector.

MAINTAINING WATER QUALITY Sonja B. Thomas, Coordinator - Pesticide Safety Education Program; and John Everest, Professor Emeritus, Crop, Soil and Environmental Sciences, Auburn University

Clean water is of great concern for all Americans. Almost all potable water supplies come from surface or ground water. Surface water is derived from above-ground sources such as lakes, streams, ponds, or other impounded bodies. Ground water is found in zones beneath the earth’s surface, which are called aquifers. Aquifers are formations of rock, sand, or gravel in which all pore spaces are filled with water. Aquifers serve as the source of fresh water for wells and springs. Water originates as rain or melted snow, which either accumulates on the soil surface or percolates through the soil to the water table and into ground water. Many human activities can have a detrimental effect on water quality. Contamination from industrial wastes, petroleum products, fertilizers, manures, and municipal sewage and septic tanks all affect the quality of our surface and ground water. Actions have been taken on a national scale to eliminate or to minimize the effects of these sources of possible contamination. Agricultural pesticides may also contaminate aquifers or surface water sources. Pesticides enter surface and ground water because of the actions of the landowner. Pesticides can enter water directly through accidental spills, back siphoning, intentional excessive pesticide application, improper application, improper disposal of rinsates, improper container disposal, and through poorly constructed or maintained wells. These situations are all avoidable and can be prevented with greater attention to proper management practices and through upgrading application equipment. Pesticides can enter water indirectly through normal leaching in the soil after application or through surface runoff (or surface-loss). Contamination due to surface-loss from agricultural fields can be reduced in part by modifying farming practices. Contour farming, no-till farming, and strip farming can reduce the movement and flow of water, thereby minimizing any soil erosion from sloped fields. In some cases, selecting the appropriate pesticide can reduce the potential for leaching and for surface-loss as well. Each agricultural chemical or pesticide used today has different water solubility and other chemical characteristics that

affect its behavior in and on soils. The solubility and behavior of a pesticide in the soil is dependent in part on the soil texture, soil type (morphology), and organic-matter content. These factors all affect the degree of soil absorption of a pesticide. Soils with a high organic-matter content or with considerable amounts of clay in their structure tend to strongly adsorb pesticides, thus reducing leaching. However, coarsetextured sandy soils low in organic matter have low adsorption, which tends to permit downward leaching of pesticides. A knowledge of your particular soil type and soil texture will help in selecting pesticides which have limited potential for surfaceloss or leaching. In places where soils are very sandy or gravelly with little organic matter, a producer should select a pesticide that has only small or medium leaching potential. Use of a chemical with a large leaching potential in this situation could lead to contamination of ground water. In situations where fields have considerable slope or in areas where soil is permanently saturated with water, it is advisable to use a pesticide that has a small to medium potential for surface-loss. In areas where ground water is quite shallow, there is a good possibility that pesticides can enter the ground water through leaching. In areas of limestone composition, it is possible that pesticides can enter ground water through developing sinkholes. In these situations, selection of pesticides used in agricultural production is critical to prevent possible contamination of surface and ground waters. In the following tables, water quality information is listed for insecticides and acaricides and for fungicides and nematicides, respectively. The pesticides are listed alphabetically by common name. The surface-loss potential indicates the tendency of the pesticide to move with sediment in run-off. The leaching potential indicates the tendency of the pesticide to move in solution with water and to leach below the root zone into deep percolation. Water quality information for herbicides is listed with the weed control recommendations in each section.

Christmas Trees IPM-1296

Disease Control Recommendations for 2013

Disease control is an important part of Christmas tree production. Normally, diseases are responsible for the loss of few trees, but they often reduce tree quality as well as value in the market place. Good management should limit problems with most diseases. Foliar fungicides may be needed to control needlecast of pines and phomopsis blight on red cedar (Juniperus species). Christmas Trees: Disease Control Disease

Fungicide and Formulation

Eastern Gall and Fusiform Rust myclobutanil EAGLE 20EW

A preventive fungicide spray program, begun on secondyear trees and continued until harvest, should provide good protection from these diseases. When applying fungicides, be sure to wet all the foliage, not just the outer needles. A list of fungicides and spray intervals is found in the following table. Consult the label for specific application instructions.

Everest, Professor Emeritus, Crop, Soil and Environmental Sciences, Auburn University.

PESTICIDE TOLERANCES AND RESTRICTIONS Many pesticides presently used in commercial orchard programs are hazardous to the operator unless proper precautions are followed. This is especially true of parathion, azinphosmethyl (Guthion), dimethoate (Cygon), and demeton (Systox). Always read the label when using pesticides and observe the recommended precautions. Pesticides are relatively safe when used as recommended, but they are a potential liability in the hands of a careless operator. Therefore, the orchard owner or the manager is directly and legally responsible for the effective and safe use of all pesticides. Important Precautions to Observe When Handling Pesticides 1. Read all labels and recommendations before using pesticides. Avoid breathing wettable powder while opening the bags or putting it in the spray tank; avoid inhaling the spray mist during the spraying operation. While handling the wettable powder and when spraying or entering sprayed areas, wear a respirator recommended for protection against parathion and Guthion. 2. Wash your hands, arms, and face after handling pesticides and especially before eating or smoking. Bathe and change your clothes immediately after finishing spraying. Change clothes daily during sustained spraying periods. 3. If you are working where there is considerable spray drift or dust, wear protective covering. A light plastic raincoat gives good protection. A cellophane sheet also gives protection; cut a hole large enough for your head in the center of the sheet and then simply drape it over your shoulders. Wear a washable rubber or plastic rain hat. 4. Never handle wettable powders with bare hands. If you must handle them with your hands, wear natural rubber gloves — never synthetic rubber, leather, or cloth.

5. The symptoms of parathion or Guthion poisoning include blurred vision, weakness, nausea, cramps, diarrhea, and tightness or discomfort in the chest. If any of these symptoms occur while spraying with either of these pesticides, contact your doctor immediately and tell him or her what you suspect. Follow all precautions on pesticide labels with reference to time, application rate, and total amount to apply per acre. Nutritional Sprays Foliar sprays of calcium and boron may be needed to prevent deficiencies. Problems related to calcium and boron deficiencies are cork spot and bitter pit of the fruit and “measles” in the bark of young trees. Boron Sprays. Use foliar analysis to determine need for boron sprays. If the leaf level of boron is below 30 ppm, a spray using 2 pounds of Solubor per 100 gallons of water (3 pounds per acre) should be applied during October while leaves are still functional. If the Solubor spray is not used in the fall, it may be applied in the spring during bloom. No boron should be applied if the leaf level is above 45 ppm. Young trees may be sprayed with Solubor at 0.5 pound per 100 gallons of water in the first two cover sprays. Calcium Sprays. Calcium sprays using 2 pounds of calcium chloride per 100 gallons of water (3 pounds per acre) should begin with the first cover spray. A total of three sprays should be applied at 2-week intervals. If a wetting agent is included in the cover sprays, no additional surfactants will be needed. For maximum benefit, apply a dilute spray when air temperature does not exceed 85°F. Growers having postharvest problems with bitter pit should consider using calcium chloride, as above, beginning the first week of June and continuing every 2 weeks until harvest. To minimize the russetting effect of sprays on Golden Delicious, do not apply during cool, moist weather or in the evening.

PESTICIDE PRECAUTIONS Many pesticides now used in commercial orchard spray programs are hazardous unless you follow proper precautions. This is especially true of parathion, azinphosmethyl (Guthion), and endosulfan (Thiodan). Always read the label when using pesticides and observe the recommended precautions. Pesticides are relatively safe when used as recommended, but they can become a potential liability in the hands of a careless operator. The orchard owner or manager is directly and legally responsible for the effective and safe use of pesticides. The most important precautions to observe when handling pesticides include: 1. Avoid breathing wettable powder while opening the bags and putting it into the spray tank. Avoid inhaling spray mist during a spraying operation. Work to windward. While handling wettable powder and when spraying or entering sprayed areas, wear a respirator recommended for protection against parathion or Guthion. 2. Wash your hands, arms, and face after handling pesticides and before eating, smoking, etc. 3. If you are working under conditions that involve considerable spray drift or dust, wear protective covering. A

light plastic raincoat also gives protection; or, cut a hole large enough for your head in the center of a plastic sheet and simply drape it over your shoulders. Wear a washable rubber or plastic rain hat. 4. Never handle pesticide wettable powders with bare hands. If you must handle a powder, wear natural rubber gloves for protection—not synthetic rubber, leather, or cloth gloves. 5. Keep on hand for emergency use under medical direction a supply of atropine tablets, 1/120 (0.5 mg). The symptoms of parathion or Guthion poisoning include blurred vision, weakness, nausea, cramps, diarrhea, and discomfort in the chest. If you feel any of these symptoms while spraying with parathion or Guthion, quit spraying, take two atropine tablets at once, then consult your doctor immediately and tell him or her what you suspect. 6. Follow directions and recommendations to keep the residue on the fruit within the legal limits. Follow all precautions on the pesticide label with reference to time, application rate, and total amount to apply.

Commercial Pecan IPM-0027


DISEASE CONTROL Current disease control recommendations for commercial pecans are available from the Georgia Pecan Extension Website at http://www.caes.uga.edu/commodities/fruits/pecan/. Click on the 2013 Pecan Spray Guide under the quick links section to find the latest recommendations for insecticides, fungicides, and nematicides used in pecans.

Since Georgia conditions are similar to those in Alabama, nearly all information provided is applicable to Alabama. However, there are state label registrations on specific pesticides that differ from one state to the other. Always verify the use by reading the label before purchasing and using the pesticide.

WEED CONTROL Herbicides are recommended for pecan orchards to provide an 8- to 12-foot-wide, weed-free strip between the tree rows. This weed-free strip between rows will reduce weed competition in both the young and the old trees, and it will help increase harvesting efficiency as well as prevent mower damage.

Keep the area between tree rows as a mowed sod, 1 inch or less in height. This sod-herbicide system provides an allweather roadway for spraying and harvesting equipment and is an effective floor for mechanical harvesting. Also, this system eliminates mechanical disking, which often damages pecan roots and spreads crown gall.

PECAN MANAGEMENT CHECKLIST Each year, the pecan producers who get maximum returns from the dollars they invest in pecan growing are those who carry out certain key management practices. Use this maximum return checklist to check up on your pecan management system. If you cannot mark off each of these points for your own operation, you may be missing out on maximum returns. □ Test fertility annually and follow recommendations. Get a leaf analysis and soil test in each orchard every year. Poor soil fertility, including deficiency in both major and minor elements, is a severe problem in unmanaged orchards. Maintaining good soil fertility and pH of 6.5 or better is essential for profitable yields year after year. □ Scout orchards regularly for problems. Have a trained person check thoroughly at least once a week during the growing season. Some growers hire consultants or scouts while others prefer to check their own orchards. Scouting allows for the proper timing of control measures, helps identify pest problems, and provides the records needed for planning pest control in future years. Scouting can also tell you how effective your applications have been and how complete your spray coverage is. Except for fungicides, automatic applications of pesticides are a poor investment. Select and apply pesticides recommended for the specific pests present. Observe “threshold levels” where they have been established for particular pests. □ Irrigate if economically feasible. Timely irrigation increases the average yield and quality of pecans. It provides a measure of insurance against loss during dry years, and it can help ensure that an orchard bears annually. Before installing irrigation, however, study the costs to find out if irrigation is economically justifiable in your orchard. □ Maintain orchard sanitation. Remove all the limbs, shucks, old nuts, and excessive ground cover to reduce any insect pest problems, disease incidence, and weed competition. Make it a practice to keep your orchard clean. □ Prune and train young trees. Pruning and training is a must for development of strong, well-balanced trees and to ensure a maximum fruiting surface. Older, established trees that present a closed canopy should also be pruned to allow sunlight penetration and to increase fruiting surface. Thinning of trees in older orchards may be needed. □ Use sod-strip weed control. Use herbicides to create a 10- to 14-foot-wide weed-free strip within the tree rows. Row middles may be planted in winter annuals or legumes or established in perennial summer grasses. Creation of the weedfree strip reduces weed competition in both young and old trees and lessens the possibility of cultivation and mower injury to trees. □ Do not cultivate under trees. Pecan trees generally have shallow feeder-roots, and cultivation can injure or sever them. If crown gall is present in the orchard, cultivation can spread this disease from tree to tree as the roots are cut.

□ Keep middles under control. Lush growth of winter annuals during the spring can cause problems. If this situation exists, clip row middles closely as soon as the spray program is started. Keeping row middles controlled during the pecan growing season will reduce weed competition and humidity, help permit good air flow in the orchard, and eliminate breeding areas for some insect pests. □ Apply a budbreak fungicide spray. Scab infection of young leaves can begin immediately after budbreak. Apply the first fungicide sprays in time to protect the developing foliage against infection. Early application of fungicide is essential to keep scab incidence low throughout the remainder of the growing season. □ Control diseases using a regular spray program. Begin your fungicide spray program at budbreak and maintain a 14to 21-day schedule throughout the growing season. Early in the season and during humid periods, use the shorter interval for better control. Use the recommended rate of fungicide and at least 10 gallons of spray volume per tree for good coverage. □ Don’t spread crown gall. When planting new trees, do not use any which have galls or abnormal growths on the roots. Rid the orchard of berry vines, which are a natural host for crown gall, and don’t spread crown gall by cultivating or mowing close to trees. □ Use beneficials when possible. Based on careful scouting, allow low levels of damaging foliage-feeding pests early in the season in order to help build up a beneficial insect population. These insects can help keep even larger infestations of damaging insects in check later in the season. □ Use trapping to detect nut pests. Pests such as the hickory shuckworm and pecan weevil are best detected by traps. Blacklight traps are essential for determining shuckworm populations. Cone emergence traps allow detection of weevil emergence patterns. Time insecticide applications by the findings of such traps. □ Maintain orchard pest infestation records. Complete yearly records will help you identify pest hot spots and annual trends in each orchard. For more information and for specific recommendations, contact your Extension county agent. You can get detailed information applicable to conditions in your area. You can also get cost-and-return budgets and up-to-date publications on pecan production.

Insect, Disease, and Weed Control Recommendations for 2013

INSECT AND DISEASE CONTROL Current insecticide, miticide, and disease control recommendations for commercial vegetable crops in Alabama can be found in the Southeastern U.S. Vegetable Crop Handbook. Copies of this handbook can be downloaded by going to the following link: http://www.thegrower.com/southeast-vegetable-guide/ You will need Adobe Reader to download the different sections. The handbook contains the latest recommendations for fungicides, nematicides, fumigants, and herbicides as well as discussions and recommendations for all aspects of commercial vegetable production including variety and fertilizer recommendations. Depending on the crop and pest, there may be other crop protectants or strategies available to aid in their management. In addition to conventional management methods for insect and mite pests, there are alternative management practices offered for several pests on many vegetable crops. The handbook is a collaborative effort by Extension specialists and researchers from land grant institutions in the southeastern United States. The management practices presented in the handbook are considered the preferred or best management practices (BMPs).

Insecticide Premixes The Southeastern Vegetable Crop Handbook does not contain information about insecticide premixes although numerous formulations are available in the market today. Here are some examples: • ATHENA (FMC): bifenthrin + abamectin B1 • BRIGADIER (FMC): bifenthrin + imidacloprid • COBALT (Dow AgriSciences): chlorpyrifos + gammacyhalothrin • DURIVO (Syngenta): chlorantraniliprole + thiamethoxam • HERO (FMC): zeta-cypermethrin + bifenthrin • LEVERAGE (Bayer): imidacloprid + beta-cyfluthrin • STALLION (FMC): zeta-cypermethrin + chlorpyrifos • STEED (FMC): zeta-cypermethrin + bifenthrin • VETICA (Nichiho): flubendiamide + buprofezin • VOLIAM FLEXI (Syngenta): chlorantraniliprole + thiamethoxam • VOLIAM XPRESS (Sygenta): chlorantraniliprole + lambda-cyhalothrin For organic insecticide recommentation and alternative IPM tactics, refer to the following Extension publications: “What is Organic?” (ANR-1425), “Pest Management In High Tunnel Crop Production” (ANR-1432), and “Organic Insecticides” (ANR-1428). For tips about insect monitoring using pheromone traps, refer to the publication “Pheromone Traps for Monitoring Insect Pests” (ANR-1431).

DISEASE CONTROL Current disease control recommendations for commercial small fruit production in Alabama can be found on the IPM/Production Guides page of the southern region small fruit consortium website: http://www.smallfruits.org/ SmallFruitsRegGuide/index.htm Here you can view and download integrated management guides for blueberries, brambles (blackberries and raspberries), bunch grapes, muscadine grapes, and strawberries. Copies of the guides are available through your county Extension office.

The integrated management guides contain the latest recommendations for insecticides, fungicides, nematicides, and herbicides for commercial small fruit production. The guides are a collaborative effort by Extension specialists and researchers from land grant institutions in the southeastern United States.

WEED CONTROL Controlling weeds with herbicides in the row of fruit crops is a sound production and harvesting practice. Herbicides should generally be applied in 20 to 40 gallons of water per acre. Where the weeds are short (4 inches tall or less), 15 to 20 gallons per acre will provide adequate coverage. However, taller weeds require a higher volume of spray mix per acre. Operate the herbicide sprayer in a pressure range of 20 to 40 psi. If operated at higher pressures, drift becomes a problem and can lead to damage. Another important factor is the height of the boom above the ground. To get properly designed overlap, the height should be 18 inches for 80-degree series

nozzles. The following information can help you set up your sprayer correctly: At 30 psi and 4 mph, a Spraying Systems Teejet 8004 nozzle will deliver 26 gallons per acre. At the same pressure and speed, an 8005 nozzle will deliver 32 gallons per acre; 8006, 39 gallons per acre; 8008, 52 gallons per acre. To help you calibrate your herbicide sprayer, see Extension Circular ANR-570, “Equipment and Calibration For LowPressure Ground Sprayers.”

GRAPES The herbicides listed in the following table are all labeled for use on grapes. They will control a number of problem weeds but not all of them. Some perennial weeds, such as nutsedge and briars, will not be controlled by any of these products. Generally, the low rate given should be used on coarse-

textured soils with low organic matter, and the high rate should be used on heavy clay soils. Always read the herbicide label before using to determine the appropriate rate and observe all use precautions. Rates given are based on a treated-acre basis, not on a planted-acre basis.

Gramoxone directed as needed during the summer. First Year—year of planting 4. Solicam in November. 1. Surflan after the soil has settled. 2. Poast or Fusilade for perennial grasses as needed. Third Year, and years thereafter 3. Gramoxone applied with a shielded sprayer during 1. Casoron in January. the summer for emerged weeds. 2. Surflan or Devrinol in March. 4. Solicam in November. 3. Simazine plus Gramoxone Extra in April. 4. Glyphosate as needed during the summer. Second Year 5. Solicam in November. 1. Surflan or Devrinol in March. 2. Simazine plus Gramoxone in April.

STRAWBERRIES Several different cultural systems are used in the Southeast for strawberry production. In Alabama, some strawberries are grown in a 3-year cycle using a matted-row system of culture. The first year is spent establishing a good population of plants with berry harvesting occurring in the second and third growing seasons. Good weed control in strawberries grown in matted rows is difficult; however, the program in the following table should make the task easier. Any step in this program may be omitted

when weeds are not present at the suggested time of treatment. In fields where irrigation is not practiced, weed control may be inconsistent. Also, weeds should be present before applications of 2,4-D are made. Another cultural system for growing strawberries is the annual hill plasticulture system. This is a system where strawberries are planted annually on a raised bed covered with black plastic. See Extension Circular ANR-633, “Commercial Strawberry Production,” for more information.

Table 2. Strawberry Weed Control

Herbicide Trade Name Herbicide Common Name (Rate/Acre Broadcast) (Active Herbicide/Acre) Comments Matted Row During Year of Establishment (First Growing Season)

STEP 3: See Comments.

Mechanically remove or hand-pull weeds from the rows in late June. Cultivate the middles with flat sweeps run shallowly or use a directed application of Gramoxone in the middles with a shielded sprayer. See below for rates and instructions.

GRAMOXONE LS (2-4 pt.) + Non-ionic Surfactant

paraquat (0.5-1 lb.) + non-ionic surfactant

STEP 4: See Comments. AIM 2EC (0.5-1.6 fl.oz.)

Apply as a postemergence hooded spray in row middles for control of emerged annual broadleaf weeds and annual grasses during the year of crop establishment. Apply in 20 to 40 gallons of spray mix per acre using shields to prevent spray contact with crop plants. Add a non-ionic surfactant at 0.5 to 1 pint per 50 gallons of spray solution. Does not provide residual activity. DO NOT make more than three applications per crop season. DO NOT apply within 21 days of harvest. Gramoxone is a RESTRICTED USE pesticide. MOA–Photosystem I inhibitor Apply Aim to row middles in July or August.


STEP 5: 2,4-D AMINE (several formulations)

Apply in row middles using a hooded sprayer to prevent contact with the crop. Add a non-ionic surfactant at 2 pints per 100 gallons of spray mix. Controls several annual broadleaf weeds. MOA–PPO inhibitor

2,4-D (0.5-0.025 lb.)

Apply in late winter for control of existing braodleaf weeds. Use the lower rate on small weeds to minimize crop injury. Some crop injury may occur but strawberry plants will recover. Apply 2,4-D as a spot treatment to minimize crop injury. MOA–Synthetic auxin

For Established Beds (Second and Third Growing Seasons)

The weed control program for established strawberry beds is outlined below. Herbicide rates to use are given in the table above. After strawberry harvest during the third growing season, many strawberry producers destroy existing plants

and establish new beds during late fall or winter. If the existing strawberry beds are to be carried into the fourth growing season, follow the remainder of the program listed in the outline.

Three-Year Herbicide Program (Matted Row)

First Growing Season—Year Of Establishment January or February Plant strawberries; apply Dacthal or Devrinol March Apply Poast or Select Late June Cultivate or apply Gramoxone or Aim in hooded sprayer July Cultivate or apply Gramoxone or Aim in hooded sprayer September Hand-weed rows January or February Apply 2,4-D Amine** followed by Dacthal or Devrinol Second Growing Season March to May June July August January

Table 2. Strawberry Weed Control (cont.)

Annual Hill Plasticulture

STEP 1. If possible, select an area that is free of perennial weeds, such as nutsedge, trumpetcreeper, or dewberry. STEP 2. Follow procedures for fumigation and planting as described in Circular ANR-633. STEP 3. Weed control in the middles can be accomplished using the herbicides listed in the matted row section. Weed control over the plastic will be limited if weeds emerge through planting holes in the plastic. Poast can be used to control grasses. Broadleaf weeds such as vetch and Carolina geranium can be controlled with 2,4-D, but strawberry varieties differ in their tolerance to this herbicide. Hand weeding may be required. Table 3.

Chemical Weed Control Recommendations for 2014

There is nothing simple, automatic, or easy about controlling weeds in home lawns. Each lawn or home situation is different. There are different lawn grasses, different soils, different ornamental plants, and different weed problems. Also, different degrees of management will be used in maintaining the lawn. All of these factors must be considered when attempting to control weeds. The first step in any weed control program is to identify the weed or weeds that are a problem. Often, a homeowner cannot identify the different weeds. Personnel in the county Extension office, local nurseries, and lawn and garden centers can provide the necessary identification. Once problem weeds have been identified, it is then important to select the appropriate herbicide product for the situation and target weeds. No single product will control all the weeds, and no single product can be used in all lawn grasses or in all situations. Herbicide products available to homeowners are packaged in small containers—typically in pints and quarts. These products are manufactured in diluted forms for ease of application and for safety as well as to reduce the overall cost. Each product contains one or more different herbicides. Although several products sold by different companies contain the same herbicides, they may differ in concentration of herbicides, ratios, and/or chemical form. Selecting the herbicide product to use is made more difficult by the fact that lawn grasses behave or respond differently to each herbicide. Some herbicide products will have different rates for different lawn grasses. The applicator should abide by these rates when making the application. The product label is the best source of information as to which lawn grasses can be treated with the particular product. Read the label carefully before purchase and use the information to ensure safety to the applicator as well as the home lawn setting. There are several terms that are used throughout this section on weed control which should be defined. Preemergence herbicide: A herbicide that is applied to the lawn grass surface before problem weeds germinate and emerge from the ground. These herbicides must be applied before a weed problem develops. Usually, preemergence herbicides are ineffective when applied to emerged weeds. Postemergence herbicide: A herbicide that is applied after weeds have emerged, but while they are small and actively growing. This type of herbicide is applied to the leaf and stem tissue of the problem weeds. Generally, postemergence herbicides will not control weeds that germinate and emerge after the application.

Non-selective herbicide: A herbicide that kills all vegetation treated. Typically, these products are applied to the foliage of the weeds. This type herbicide will also severely injure or kill desirable plants. The non-selective herbicide products listed in this publication do not have any soil activity; that is, they are not soil sterilants. RTU: An abbreviation that stands for “Ready To Use.” It is used to designate the products that are manufactured in a ready-to-use state. In other words, the product requires no additional water or handling and is typically available in a spray- or applicator-type container. “Green-up” period (transition period): A short period of time in the spring and/or fall when desirable lawn grass is emerging from its dormant state. It is during this period that grasses are most sensitive to herbicides and, in many cases, the herbicide labels prohibit their use. Granular herbicide forms can be applied with a drop- type fertilizer spreader. Herbicide products available in a liquid form must be mixed with water prior to use and applied in some type of applicator which will provide uniform application. Homeowners typically use devices such as hose- end sprayers, pressure- or pump-type sprayers, or the more sophisticated backpack sprayers. Generally, equipment used for applying herbicides should no longer be used for treating desirable plants. It is difficult to remove all traces of herbicides from spray applicators. It is possible that herbicide contamination could cause problems on desirable shrubs, flowers, or trees. The volume of water or spray solution to use when making a herbicide application is suggested on the herbicide container label. Generally, when pump-up sprayers are to be used, most herbicide labels suggest that 2 to 4 gallons of herbicide spray mix be applied per 1000 square feet of lawn surface. However, when hose-end sprayers are used, many herbicide labels suggest that 4 to 6 gallons of herbicide spray mix be applied per 1000 square feet of lawn surface. Read the label carefully to determine the spray volume as well as the other necessary application instructions before using the herbicide. Following is a list of herbicides currently recommended for use on home lawns.

Comments

Provides preemergence and postemergence control of broadleaf weeds and annual bluegrass. Control of summer annual grasses is weak. Atrazine may be applied anytime to St. Augustine and centipede grasses except during “green up.” Best results occur when application is made before weeds emerge or when still small. Two applications of atrazine during a single year may be needed to control some hardy weeds. See label for appropriate rate and times of application. DO NOT apply to cool-season grasses such as fescue, ryegrass, or bluegrass. DO NOT reseed for 4 months before or 6 months after herbicide application. Rain or irrigation is needed within 7 days after application for consistent control. See label for additional application instructions.

Provides preemergence control of annual grasses and several broadleaf weeds. Irrigate treated area after application to activate herbicide. DO NOT apply to newly sprigged areas. DO NOT reseed treated areas.

Provides preemergence control of annual grasses such as crabgrass and foxtails and some small-seeded broadleaf weeds such as spurge. Will provide postemergence control of small crabgrass less than 4 weeks old.

Comments

Provides the broadest spectrum of broadleaf weed control. Best results are obtained when weeds are small and actively growing. To ensure actively growing weeds, water 2 to 3 days prior to spraying. This combination works faster when applied at temperatures above 70°F. Use the low rate on St. Augustine and centipede grasses and the high rates on zoysia, bluegrass, and fescue lawns. Some of the products listed permit only spot treatment on St. Augustine and centipede lawns to reduce overall injury. DO NOT water for 24 hours after application. DO NOT apply when air temperature is expected to exceed 85°F. DO NOT spray within the dripline or root zone of desirable trees, shrubs, flowers, or vegetables. DO NOT reseed treated areas for 3 to 4 weeks after use. Apply in the spring when weeds are small and actively growing. Hard-to-control weeds may require a second treatment 3 to 4 weeks later. Apply when air is calm to avoid spray drift to desirable ornamental plants. DO NOT water for 48 hours after use. Water regularly thereafter to maintain a quality lawn. On newly established lawns, DO NOT use until grass has been mowed three or four times. DO NOT reseed sod or sprig treated areas for 3 weeks after use.

Weed Control Recommendations for 2013

Residential landscape plantings soften the architectural design of buildings, provide color and texture to the landscape, and increase the monetary and aesthetic value of property. Such plantings may be only several square feet in size or may occupy several thousand square feet. A single planting may consist of an individual plant, shrub, or tree, or it may contain a complex layout of different ornamental shrubs, bulbs, ground covers, and flowers. It is the mixture of plant species in an ornamental planting that makes weed control difficult, if not impossible. This section will review the possible weed control alternatives available to homeowners and landscape managers. Weeds are survivors or invaders of open habitats. The planting area is an ideal environment for the growth of weeds. The environment usually includes exposed or loosened soil, good availability of nutrient elements, and generally favorable moisture. While these factors favor good healthy ornamental plant growth, they also aid in the growth of weeds. Control Practices Four general practices can control most weed problems in residential landscape plantings. Control practices include using measures that limit weed growth in desirable areas. These practices usually result in reducing the severity of weed problems rather than completely eliminating them. Using only one method of control usually results in partial success. The most successful effort involves using two or more practices in a weed control effort. The four practices are (1) clean sanitation; (2) mechanical practices; (3) cultural practices; and (4) the use of herbicides. Clean Sanitation. These practices involve the continuous use of seed, mulch materials, soil, and plant materials that are weed-free. No soil area in the landscape is completely devoid of weeds. But, new weed problems are frequently introduced into the landscape area by using weed-contaminated soil, seed, or plant material. Contaminated mulching materials are other possible sources of weed introduction. Examine all seed, plant material, mulches, and new soil before introducing them into a new planting area. If weeds, weed seed, or vegetative weed propagules (bulbs, tubers, or rhizomes, for example) are present, strongly consider using another material. Weeds are a lot easier to control before they are introduced than after they are established in a landscape planting. Mechanical Practices. Hand and mechanical removal of weeds are the oldest methods of control. Hand pulling and hand hoeing are the safest, most effective and practical control methods. These methods are also most useful in small areas or in areas of mixed plantings of desirable ornamental plants where herbicide use would be impractical.

Mechanical control may also involve the use of tillers, edgers, or other equipment to remove existing weed problems. Tillers are useful in preparing a weed-free seedbed prior to planting as well as in removing small weeds emerging after planting. Shallow cultivation is useful in removing small weeds. Edgers remove marginal weeds that encroach in ornamental plantings. Cultural Practices (mulching). Mulching provides many benefits in ornamental plantings in addition to weed control. Mulching retains soil moisture, reduces erosion, reduces soil temperature, improves soil tilth, and suppresses weed seed germination and weed establishment. Mulching materials include straw, leaves, pine bark, old newspapers, and landscape fabric. When used properly, alone or in combination, these materials will shade the soil and prevent many weed seeds from germinating. Herbicide Use. Chemicals used to control weeds are called herbicides. The use of herbicides for weed control is only a short-term solution to a weed problem. Other control options, such as mulching or mechanical removal, offer safer and more long-term results. It is very important to select and use herbicides properly. Misapplication of herbicides can cause them to fail to control weeds, to injure ornamental plants, and even to be dangerous in some situations. Herbicides labeled for use in landscape plantings have been tested by chemical companies and are approved for use by the Environmental Protection Agency (EPA). Herbicide labels provide specific instructions for use and safety precautions. It is the best source of information concerning the use of any product. Generally, there are two opportunities to control weeds in a landscape planting. Weeds can be controlled in some established plantings by applying a herbicide to weed-free soil prior to the germination of weed seeds and emergence of weed seedlings. This type of herbicide application is termed a preemergence application using a preemergence herbicide. The herbicides are effective only on soils that have no weed growth present, and they prevent the germination or emergence of some weeds. Preemergence herbicides do not control all weeds. The herbicide label identifies the spectrum of weeds controlled. These same herbicides cannot be used around all ornamental plants. It is important that you read the herbicide label and be sure that all ornamental plants in the planting are included on the label before purchasing and using the herbicide. The other opportunity to control weeds is to apply a herbicide to emerged weeds present in the planting. This type of herbicide application is termed a postemergence application using a postemergence herbicide. Postemergence herbicides are

www.aces.edu


effective in controlling small weeds that are actively growing at the time of treatment. Herbicides that can be applied safely over the top of some desirable plants (but kill target weeds) are termed selective herbicides. There are not many selective postemergence herbicides for use around ornamental plants. Selective postemergence herbicides do not control all emerged weeds, so effective herbicides have to be matched with the desirable ornamentals present. Herbicides that kill most or all plants treated are called nonselective herbicides. These products will severely injure or kill desirable landscape plants. Calibration To achieve maximum effectiveness from any herbicide, it is critical that application equipment be properly calibrated before using it to apply the recommended herbicide rate over the treatment area. Applying too little herbicide will give poor results; applying too much will cause plant injury and excessive chemical cost. To apply a liquid herbicide spray uniformly, it is generally recommended that 20 to 40 gallons of spray solution be applied per acre of land (0.5 to 1 gallon of herbicide spray solution per 1000 square feet of soil). Safety Before being sold to the public, all herbicides are thoroughly tested to assure that they are effective and safe when used properly according to label directions. By their nature, herbicides are toxic. Pesticides are placed in three categories

based on toxicity: DANGER (highly toxic), WARNING (moderately toxic), and CAUTION (low toxicity). Most of the preemergence and postemergence herbicides are in the WARNING and CAUTION categories. The herbicide label contains the toxicity category along with instructions to the user describing risks and benefits. The time taken to read the label is probably the most valuable time spent in weed control. Herbicide Selection Selection of the correct herbicide is one of the most critical decisions in developing an effective weed control program. It should include not only the weeds to be controlled and the plants to be treated but also the environmental conditions and nontarget plants. Herbicide labels give valuable information as to the growth stage, time, and method of application for the target weed species. Many ornamental species are listed on some labels, but because there are too many species and cultivars, no herbicide has been tested on all possible plants used in ornamental plantings. Use on species not listed on the label may result in damage to desirable plants. Trial usage should be limited to a small area. The listings in Table 1 are general characteristics of herbicides labeled for use in ornamental plantings. This information is not meant to take the place of the specific herbicide label but is intended to offer useful information to aid in the selection process.

Making Your Garden Vegetables Less Susceptible to Insect Damage Integrated pest management or IPM is the judicious use of multiple pest management tactics when pest populations reach above the action threshold. The action threshold is simply the level of pest populations at which control should be implemented to avoid damage to the crop. Action thresholds help determine both the need for control actions and the proper timing of such actions. Homeowners and gardeners can practice IPM by using insecticides as a last resort, by employing alternative pest management strategies, and by conserving natural enemies. There are many ways to reduce or eliminate the need for insecticides; some of these are described in the sections that follow. To stay informed about pest occurrences, management recommendations, and the latest IPM information, readers may subscribe to the “Alabama IPM Communicator” newsletter, an official publication of the Alabama IPM Center. To subscribe, please send an email to [email protected] or visit the newsletter archive at www.aces.edu/go/128. You can receive rapid updates by subscribing to the Alabama Vegetable IPM channel on Facebook. Healthy Soil Healthy soil will result in plants better able to resist insects and diseases. Before planting, the garden soil should be turned over and organic matter, such as manure or compost, should be added to supply essential nutrients. Organic nutrients are released slowly, in contrast to synthetic fertilizers, which provide “quick-fix” nutrients. When possible, compost should be purchased from a trusted local source; buying poor quality compost may result in insect infestations like maggots and grubs. Sustainable Pest Management Practices In order to establish more sustainable gardening practices gardeners should try to reduce their dependence on the use of pesticides. The USDA National Organic Program Standards for Pest Management provides some excellent steps that can be used in vegetable gardens. These standards are three-tiered recommendations that are as follows: Level 1: Systems-based practices. These include cultural tactics such as variety selection, crop rotation, water management, sanitation (starting with clean fields), trap cropping, and companion planting. Level 2: Mechanical and physical practices. These include installing barriers like insect netting and row covers; using

lures, traps, and repellents; regular mulching; and hand removal of insects from foliage. Level 3: Biorational and other insecticidal materials. Only approved insecticides can be used in commercial organic farming. Home gardeners can also use these organic insecticides some of which are very expensive; thus, cost could be a limiting factor. Home gardeners who wish to garden more sustainably may also use conventional insecticides but only on an as-needed basis and only in hot spots, specific areas of infestation. Prevention of pest establishment is more important than therapeutic treatment of insects in the garden. For a specific list of organic insecticides, refer to the publication “Insecticides for Organic Commercial and Backyard Vegetable Production” (ANR-1428). For tips about insect monitoring using pheromone traps, refer to the publication “Pheromone Trips for Monitoring Insect Pests” (ANR-1431). Companion Planting Companion planting is the practice of strategically placing insect-repelling plants next to crops that will benefit from their repellent effects. Some plants contain or give off compounds that repel insects. For example, planting garlic among vegetables helps to deter Japanese beetles, aphids, vegetable weevils, and spider mites; basil planted near tomatoes repels tomato hornworms; and marigolds interplanted with squash or cucumbers will repel cucumber beetles and nematodes. Beneficial Insects Most insects encountered in nature are beneficial and have a critical role in the natural food chain. Therefore, a gardener should be able to identify garden insects and determine whether they are harmful or beneficial. Table 4 provides a short list of insect predators that help seek and destroy insect pests and that are commonly seen in the garden. There are also many insect parasitoids that are too small to see individually. Applying insecticides can destroy the natural balance by eliminating beneficial insects. Switching to one early season application of systemic insecticides on labeled garden vegetables can provide early season insect control and allow establishment of natural enemies. Crop Rotation Planting vigorous vegetable varieties and using proper crop rotation are two basic IPM tactics. Planting vegetables in a different section of the garden from year to year may help reduce pest infestation by disrupting insect life cycle. Some

insect pests overwinter in the garden soil and emerge in the spring and begin searching for food. If the plant they prefer to eat is located several yards away, the insect must move to the source. Many will die along the way or will fall prey to birds and other predators. Also, many vegetables remove nutrients from the soil; by rotating vegetable crops each year within the garden, the soil in a particular section will have the opportunity to rest and regenerate. Diversified Planting A common practice among home gardeners is to plant a single crop in a straight row. This encourages pests because it makes it easy for them to travel from one host plant to another. By intermingling different types of plants and by not planting in straight rows, an insect is forced to search for a new host plant, thus exposing it to predators. This approach also works well with companion planting. Trap Cropping If given a choice, some insects will opt to feed on one plant type over another. For example, pickleworms prefer squash to cucumbers, and leaffooted bugs prefer certain varieties of soybean and sorghum over tomatoes. Trap crop arrangement or layout is critical to the success of this IPM method. Trap plants should be planted 2 to 3 weeks ahead of the main crop. Once the trap plants have become infested, the target insect can be picked off and dropped in soapy water or the entire plant can be disposed of. For stink bug management, addition of earlyplanted trap crop (such as okra, beans, or sunflowers) followed by insecticidal or cultural pest management tactic could be beneficial. In large gardens or farm settings trap plants can be planted within the main crop in rows to attract and retain pest insects. Barriers and Traps Barriers and traps can be employed to capture or impede the movement of pests. A collar made of thick paper or cardboard placed around the stem of a plant and pressed into the soil an inch or so deep will prevent cutworms and other burrowing insects from getting into the soil around your plants. A board or thick piece of paper painted bright yellow and coated with a sticky substance, such as Tanglefoot®, will attract and intercept aphids, whiteflies, and other small flying insects. Mulch Mulching is the spreading of organic matter in the garden and around plants. It is an effective method to control weeds and serves as a refuge for predatory insects like ground beetles and spiders. Mulch also helps the soil to retain moisture, which promotes plant vigor and reduces abiotic stresses. Mulch should be added to the garden when plants are 4 to 6 inches high. Grass clippings, leaves, hay, sawdust, wood chips, and compost make excellent mulches. One drawback of using mulch may be increased numbers of slugs in the garden that feed on young and succulent plants. Insect Sampling Techniques Both pest and beneficial insects can be sampled by home gardeners to assess the level of insect activity before and after

an insecticidal spray. Some simple techniques to frequently sample insect populations include the following: • Yellow sticky cards: Many insects and spiders can be intercepted on colored sticky cards as they migrate long distances. Yellow sticky cards can be placed at several locations around a garden to monitor the aphid migration while white cards can be used to monitor thrips, certain bugs and beetles. • Drop cloth/shake cloth: Gardeners can use a drop cloth spread between the rows of vegetables to gently shake off slow-moving insect pests (such as caterpillars) and beneficial arthropods for counting. • Sweepnet sampling: Gardeners can use a sweep net for collecting insects off the plants by vigorously moving the net through crop canopy. A relatively easy way of viewing insect collection is to empty the contents of the net into a gallon-size Ziploc bag. The bag can then be frozen in a refrigerator to preserve specimens for later viewing or identification by an expert. • Pitfall traps: Pitfall traps can be placed in the ground and are excellent for estimating the population/activity of soil-dwelling insect pests and predators (like tiger beetles, ants, etc.). Proper Use of Systemic Insecticides Systemic insecticides (imidacloprid-containing products) are now available for home gardeners; these insecticides should be used in a timely manner and early in the season so that the insecticide is not present when fruits are harvested (preharvest interval). The product should be applied as a drench soon after transplanting or when the first sucking pests are noticed on leaves. A systemic insecticide also requires a few days to get absorbed and translocated throughout the vascular system of plants. For more information about proper use of the new insecticides or for IPM training, contact a Regional Extension Agent at the local county Extension office. Insect Monitoring Using Pheromone Traps Moths can be detected using pheromone traps around the garden. Research at Auburn University and elsewhere indicates that detection of the first flight of moths may indicate the need to scout crops for other life stages of the insect pest; for example, if 10 to 12 corn earworm and fall armyworm moths are found in separate pheromone traps each week, then vegetable crops should be examined immediately for larval feeding damage. To a limited extent, it may be possible to “trap out” or intercept all moths in an area using multiple traps. Pheromone traps are available for almost all major insect pests of vegetables including corn earworm (tomato fruitworm), fall armyworm, cutworm, tobacco budworm, and squash vine borer. Pheromone traps can be purchased in bulk from vendors like Great Lakes IPM (Vestaburg, MI) or in the form of kits from Internet sites like Arbico Organics (Tucson, AZ) and Planet Natural (Bozeman, MT). Place pheromone traps away from the main crop because the lure is attractive to target insects over long distances. Most lures attract male moths but some attract both sexes of the species.

Home Garden Vegetables: Insect Control Recommendations for 2013 • 3

General Recommendations for Managing Soil Pests in the Garden Many soil insect pest populations reach high numbers in grass or turf. Home gardens are often established in areas previously covered with grass. To reduce soil insect problems, thoroughly till or spade the area well in advance of planting (30 days or more) and again just before planting. This will bring soil pests up near the surface where their chances of mortality are increased. A broadcast soil insecticide applied properly 2 weeks before planting will help to control some soil insects like cutworms, wireworms, and white grubs. See the note on applying broadcast soil insecticides at the end of Table 1 for instructions on this topic. Cutworms Cutworms are greasy-looking caterpillars that curl into a C-shape when disturbed. They have a wide host range and can cause damage rapidly resulting in a thin crop stand. Cutworms are active only at night and remain buried below the soil surface near food plants during the day. They emerge to feed at night and often cut seedlings or small stems, causing the plants to fall over. Because grass and many weeds are preferred hosts, remove grass and weeds in the garden, and plow the soil well in advance of planting. Damage can also be prevented by placing a paper or plastic “sleeve” over the plant and pressing the bottom into the soil. Place the sleeves around newly set transplants or seedlings so that 1 inch is below ground level and 3 inches are above the ground. Tuna cans with the bottoms removed may also be used for this purpose. Some cutworm species can be monitored using insect pheromone traps, which can provide information about pest pressure in the neighborhood. Soil granular insecticides generally provide good control of cutworms. Wireworms Wireworms are the slender, yellowish-brown, hard-bodied larvae of click beetles. They can survive deep in the soil for

up to five years and can move up to attack the seeds or young plants. Several wireworm species prefer plants in the grass family. They are usually not a problem unless the garden is planted on land that previously contained grasses or crops in the grass family. Turning over the soil in the fall and again in the spring well in advance of planting will help to reduce wireworm populations. Soil granular insecticides provide poor control of large wireworms. Crop rotation is a long-term solution to wireworm issues. White Grubs White grubs are Japanese and May beetle larvae that are dirty white in color with the tip of their abdomen more of a blue-black; they roll into a C-shape when disturbed. The mature grubs may reach 2 inches in length. They live in the soil and sometimes feed on plant roots and tubers. About the only time they are troublesome is when parts of the lawn or sod are turned under in the spring for garden use. When gardens must be planted in these areas, prepare the soil well in advance of planting. Handpicking grubs as the sod is turned over, raked, and prepared for planting is the best method of control. Soil insecticidal granules can be applied in early spring to reduce grubs. Mole Crickets Mole crickets have brown, velvety bodies with broad front legs for digging in the soil. They have large eyes and are about 1 inch long when mature. As mole crickets tunnel through the soil, they can disrupt the root system of vegetables. They may also feed on plant roots and underground stem tissue. There are no effective soil insecticides registered for use against mole crickets in vegetables. Avoid planting the garden in areas that were previously covered with grass. If any mole cricket tunnels are observed around plants, tamp the soil back down to restore support to the root system.

Managing Pests That Feed Above Ground This section provides some non-chemical methods for management of insect pests that feed above ground. Insecticide recommendations are provided in the tables that follow. Aphids • Anchor aluminum foil to the soil for 1 foot around transplants to repel aphids. Slope the soil away from the plant so rain water and mud do not obscure the reflective surface. Foil may be removed after flowering. • Make a water trap by painting a small, shallow pan bright yellow and filling it with soapy water. Place several in the garden and refill after each rain. Or paint 6- x 8-inch cards or pieces of plywood a bright yellow (Rust-Oleum 659 or Safety Yellow). Then coat them with a thin layer of a sticky substance such as Tanglefoot. Attach them to the garden stakes with the cards at crop level. Replace the Tanglefoot as needed. • Handpick, remove, and destroy aphid colonies on plant leaves. • Knock aphids from plants with a strong spray of water from the garden hose.

• Spray plants with insecticidal soap. Test tender plants first to ensure they are not burned by the soap solution. • Aphids can transmit plant virus disease; remove and destroy diseased plants to delay spread of the virus to healthy plants. • Release insect predators like lady beetles and lacewings as soon as aphids are detected. • Parasitoids such as Aphelinus abdominalis and Aphidius ervi are effective against potato aphids. Aphidius colemani is effective against green peach aphid. Asparagus Beetles • Plant marigolds near asparagus to repel beetles. • Destroy and bury any plant refuse in the fall to remove overwintering sites. • Handpick and destroy all eggs, larvae, and adults in the morning before they become active.


Cabbage Loopers and Cabbageworms • Cover plants with a floating row cover to prevent egg-laying. • Handpick and destroy the worms. Green worms are much easier to spot on red-leaf cabbage varieties. • Spray plants with Bacillus thuringiensis when worms are still small. • Remove alternate host weeds such as wild mustard and shepherd’s purse from the garden. Colorado Potato Beetles Potato beetles are infamous for insecticide resistance to synthetic pyrethroids; therefore, use insecticides sparingly and try the following alternative management methods. • Potato beetles prefer to feed on potatoes, eggplants, and tomatoes. Rotate these preferred hosts with other crops in alternate years. • Interplant non-host crops (e.g., beans) with preferred host crops. • Handpick and destroy orange egg masses, which occur on the underside of leaves, reddish-brown larvae, and yellow and black striped adults. Two to three generations of the insect occur in Alabama and throughout the South. • Place straw mulch around plants to hinder movement of the beetles. Corn Earworms (Tomato Fruitworms) • With no controls applied, earworms usually damage only the tips of the ears of corn. Cut off the damaged tips and the remainder can be eaten. • If possible, avoid planting other vegetables near corn, a favorite food of corn earworms. • Plant and harvest corn as early as possible to avoid infestations. • Select tight-husked corn varieties for planting; this inhibits worm movement into the ear. • Beginning at the flower stage, check upper tomato leaves once per week for the small, round, white fruitworm eggs. Spray plants with Bacillus thuringiensis weekly as long as eggs are detected. Cucumber Beetles • Plant “nonbitter” cucumber varieties; the bitter compound in cucumbers attracts the beetles. • Cover young plants with cheesecloth or floating row covers until the vines start to run. • Interplant cucumbers with radishes; radish seems to repel cucumber beetles. Pansies, marigolds, and nasturtiums also repel the beetles. • Eliminate weeds in and around the garden; some weeds are hosts for bacterial wilt disease, which is spread by the cucumber beetles. Flea Beetles • Flea beetles are most numerous in the spring; therefore, plant susceptible crops later in the season. • Unless flea beetle populations are heavy, their feeding will not kill the plants nor reduce their yields; control is usually not necessary on larger plants.

• Weeds bordering the garden may serve as alternate hosts. Removing weeds will reduce flea beetle populations. Grasshoppers • Trap grasshoppers by using a 1-quart container half filled with a 10-percent molasses and water mixture. • Grasshopper populations are most damaging in late summer; a floating row cover can be used to protect late-season plantings. • Fall plowing of the garden, including fence rows and garden borders, exposes the grasshopper eggs to the weather and to insect predators. Japanese Beetles • Avoid planting the garden near lawns or in previously grassy areas. • Protect plants with floating row covers. Leafhoppers • Paint 6- x 8-inch boards a bright yellow (Rust-Oleum 659 or Safety Yellow). Then coat them with a thin layer of a sticky substance such as Tanglefoot or Tack Trap. Hang the boards at crop level. When the boards are filled with insects, wash and recoat them. • Spray plants with insecticidal soap. • Leafhoppers can transmit virus diseases; remove diseased plants to delay spread to healthy plants. Mexican Bean Beetles • Handpick and destroy the egg masses and beetles in early morning before they become active. • Interplant nonhost crops like potatoes among bean plants to disrupt egg-laying. • Soybeans are preferred by bean beetles over snap or lima beans; thus, soybeans planted nearby can be used as a trap crop. Spider Mites • Spray the underside of plant leaves with insecticidal soap or paraygenic oil. • Mites don’t like moist conditions. Keeping the foliage wet can deter mites, but it can also encourage plant diseases. • Keep plants adequately watered and stress free. Do not use synthetic pyrethroid insecticides too often to avoid mite outbreaks. • Do not mow grass located close to the vegetable garden during hot and dry weather. Squash Bugs • Remove and destroy any clusters of oval, orange-brown squash bug eggs. • Remove and destroy vines and unused fruit after harvest to eliminate overwintering sites. • Place shingles or boards near squash or pumpkin plants in spring or early summer to attract squash bugs. Then, collect and destroy the adult bugs that gather under the boards each morning. • Nasturtiums and marigolds planted near squash plants may deter squash bugs.


Squash Vine Borers • Plant squash in late summer or fall to avoid heavy vine borer infestations. • To delay infestation cover plants with a fine mesh cloth or row cover until female flowers appear. They have a bulge between flower and stem that is absent in the male flowers. • Squash varieties with long vines may continue to grow despite borer damage. • Cut open borer entry holes in the stem with a knife. Then, remove the worm and pack moist earth around the stem. This is a more labor-intensive method. View a video on YouTube at http://Youtube/2ityhiirt8 Tomato Hornworms • Handpick worms from plants during evening hours. • Bacillus thuringiensis will be effective if sprayed when the worms are small. • Dill planted next to tomatoes will serve as a preferred trap crop; handpick worms off the dill. • Do not destroy hornworms that have small, white cocoons attached to their bodies. These are parasite cocoons from which small beneficial parasitic wasps will emerge.

• Turning the soil in the fall will expose hornworm pupae to weather and predators. Bean or Cowpea Weevils • Plant resistant, thick-hulled southern pea varieties such as AUbe or Freeze-Green. • Plant beans as early as possible; then, turn plants under after harvest. • Pick shell beans when they are somewhat green. Then, blanch them before freezing. This will kill weevil eggs and larvae which are seldom seen in the frozen beans. Whiteflies • Whiteflies are rarely a problem in outdoor gardens. Make sure any purchased transplants are not infested with whiteflies (or other insects). • Paint 6- x 8-inch boards a bright yellow (Rust-Oleum 659 or Safety Yellow). Then, coat them with a thin layer of a sticky substance such as Tack Trap or Tanglefoot. Hang the boards at crop level. • Spray plants with insecticidal soap. • Use beneficial insects like Encarsia, which are very effective in enclosed areas.

How To Use The Tables In Table 1, you will find (1) the names of the vegetables grown in most home gardens in Alabama, (2) the names of the insects that are likely to attack each vegetable, (3) the common (or generic) name of the recommended insecticides, and (4) the number of days you must wait after applying each insecticide before harvesting the vegetable. This is important for the safety of anyone eating the food. In Table 2, you will find a list of common names for each recommended insecticide along with examples of commercial formulations. The common name is present on the product package where active ingredients are listed. This table also provides common formulations of the active ingredient and the application rate. Table 2 also provides some insecticides recommended for organic or chemical-free vegetable production. Note that the list of commercial insecticidal products is not all inclusive. Read the insecticide label before using any product. Home garden insecticides are available as liquids and dusts and occasionally as wettable powders. Concentrated liquid formulations must be mixed with water and applied as a spray. Some insecticides may be bought ready to use (RTU) and do not need to be mixed. They can be sprayed from the container. Dusts are also applied directly to the plants without any mixing by the home gardener. Use of dust formulations

is problematic due to uneven distribution of products and disposition of the active ingredient on only the top surface of leaves. Purchase a dust applicator that can uniformly deposit products. Also watch for drift when using dust formulations and avoid application on windy days. First, check Table 1 to identify the common name of the insecticide that is recommended for the insects that are attacking your vegetables. Then look in Table 2 to find the common formulations available and recommended application rates or rate ranges if the active ingredient has different rates for different pests. Insecticides for home gardeners are almost always grouped together at stores that sell them. Locate a product that has the active ingredient you need and inspect the label to be sure that the vegetable you wish to treat is included on the label. Remember, early detection and timely application of insecticides when insects are small can help to reduce dependence on synthetic insecticides. Refer to Table 3 for insecticide classifications, modes of action, and efficacy for controlling major insect pests of vegetables in home gardens. Finally, Table 4 provides a list of common insect predators and Table 5 lists commercial vendors that sell beneficial insects. Follow instructions provided by the vendors for releasing natural enemies.

7 (roots) 14 (tops) NOTE: Applying Broadcast Soil Insecticides Slugs and snails can be controlled in home gardens with a 2% methaldehyde bait. Consult the label for specific vegetables on which it may be used. The bait is applied to the soil surface and should not contact foliage or edible parts of the plant.

Infestations of some soil dwelling pests, such as cutworms, armyworms, and crickets can be controlled with 2% carbaryl (Sevin). Combination baits of carbaryl and methaldehyde are also available. Many soil dwelling pests can also be controlled in all vegetable crops by applying bifenthrin granules (0.115%) prior to planting at the rate of 1 pound of product per acre. Work the insecticide granules into the top 4 to 6 inches of soil and provide moisture for activation. Active ingredients available in some commercial products labeled for fire ant control in home gardens include spinosad (Fertilome Come and Get It !, Safer Brand Fire Ant Bait, and Green Light Fire Ant Control With Conserve), pyriproxyfen (Esteem Ant Bait), and (S)methoprene (Extinguish Professional Fire Ant Bait). Approximate time required for the active ingredients to give noticeable results are as follows: spinosad, 2 to 4 weeks; pyriproxyfen, 6 to 8 weeks; and (S)-methoprene, 8 to 12 weeks. No general use insecticides provide control of leafminer larvae inside leaves. Leafminer problems are frequently caused by overuse of insecticides. Hand-pick mined leaves or plant tolerant varieties.

DISEASE CONTROL The abundant selection of pesticides on the market for disease control in home vegetable gardens makes it difficult to recommend specific products by the manufacturers’ trade names. Many products have the same active ingredient, making any one of them appropriate for a specific problem. However, different brands will vary in the percentage of active ingredient contained, so the user must consult the label for the amount of product to actually mix with water. Not all brands of a single fungicide are labeled for the same vegetables or the same diseases, which is why the user must consult the label to determine if the crop or disease is listed. Follow the label and follow all safety precautions. Also, new products may be added to the selection throughout the year. In addition, EPA restrictions and precautions are subject to change at any time, according to current research results. For these reasons, the recommendations in Table 1 list only the common name (the active ingredient) of the pesticides suggested for each disease problem. Table 2 lists the various trade names available (at the time of publication) for each active ingredient. The trade name is the most prominent name on the package. To use these recommendations, (1) look in Table 1 for the name of the vegetable and then the disease that you need to treat. There you will find the common names of recommended

products and comments specific to those products. (2) Look in Table 2 for the common name (or names) that were given in Table 1 for your problem. There you will find the trade name (or names) to shop for. When you shop, you may find other products available with the same active ingredient that are not listed in Table 2 because they have come on the market since the publication of this guide. It is very important that you carefully read and follow all directions, restrictions, and precautionary statements on the manufacturer’s label before using any pesticide product. The comments in Table 1 do not cover all the information needed for safe and effective use of the fungicides. You may also find information helpful in selecting the product you prefer to use. Current insecticide, miticide, and disease control recommendations for commercial vegetable crops in Alabama can be found in the Southeastern U.S. Vegetable Crop Handbook, which is directed towards commercial vegetable farmers. Home gardeners may find its contents informative as well. Copies of this handbook can be downloaded by going to the following link: http://www.thegrower.com/south-east-vegetable-guide/ You will need Adobe Reader to download the different sections.

Weed Control Recommendations for 2013

Good weed control may determine to a large extent the success of your home garden. Weeds compete with the crop for soil moisture, sunlight, space, and plant nutrients. They compound disease problems and serve as hiding places for insects. Also, weeds may prevent dusts and sprays from thoroughly covering your garden plants, resulting in poor pest control. Weeds can usually be divided into two groups—grasses and broadleaf weeds. Grasses are multistemmed plants with fibrous root systems. Once grasses become established, they are difficult to control without injuring the vegetable crops. Grasses are very competitive in gardens and make harvesting difficult. Many broadleaf weeds grow upright and have taproot systems which make them easier to pull than grasses; therefore, the vegetables receive less injury. Preventive Weed Control. New weed seed may be brought into a garden on plows or tillers that have been used in weedy areas. Poultry litter, compost and manures sometimes contain troublesome weed seed. Weedy hay used for mulch may bring an number of new weed problems. Occasionally, home-saved vegetable seed may also include some weed seed. Most of the weed problems in the garden are homegrown problems. That is, they come from weed seed produced in the garden in years past. Season-long weed control to prevent weeds from reseeding should be a basic part of any weed control program. Controlling weeds by preventing them from making a seed crop may be a long-term process, but in the end it is the only sure way to control this problem. Mechanical Weed Control. Historically, gardeners have used hoeing, plowing, hand-pulling, and mulching to control weeds. Mechanical control methods used on a regular and continual basis provide good weed control for serious gardeners. This usually means frequent light cultivations with a plow and hoe to destroy weeds in the two- to four-leaf stage. A few minutes spent destroying the flush of weeds that usually emerge after every rain is much more effective than hours or days spent trying to destroy established weeds. Many gardeners have too large a garden to control weeds in the time available for that task. A few well-managed rows may produce greater yields of higher-quality vegetables than a larger area tended in a slipshod manner. Mechanical weed control gives immediate results. There are no problems of uniform application, drift, and residues as with chemicals. Weeds may be controlled mechanically under

a wide range of soil moisture conditions, and very little skill is required. Also, mechanical methods may be used as often as needed. Mechanical weed control is the most practical approach to weed control in small gardens. The greatest weakness of mechanical methods is the lack of residual control. Mulching. Mulch can be a valuable asset in controlling weeds in perennial and long-season crops like asparagus, strawberries, tomatoes, and peppers. Six inches of pine straw or 3 inches of leaves or well-decomposed sawdust will help suppress most weed problems. Mulch also helps keep the soil surface cool and cuts down the evaporation of soil moisture. Many gardeners clean-cultivate and mulch heavily to control weeds later in the season in crops like tomatoes, peppers, and okra because late cultivation could damage these large, spreading plants. Mulch gradually decomposes during the season, and sometimes this may cause plants to develop a slightly yellow cast. A light application of about 1 pint of ammonium nitrate per 100 feet of row will usually correct this problem. Additional mulch may be added as needed when the older material settles or decomposes. At the end of the season, the mulch can be turned under or incorporated to add organic matter to the soil. Chemical Weed Control. There are very few herbicides labeled and available for use in the home garden. These herbicides are discussed in the following table. These herbicides control only annual grasses and, in some cases, small-seeded broadleaf weeds. They usually do not give acceptable control of most broadleaf weeds. You may choose to use a herbicide to control grasses in the garden. However, you must be prepared to rely on hoeing, plowing, hand-pulling, and/or mulching to control broadleaf weeds that escape chemical treatment. Summary. Because of the high variability among vegetable crops, weed problems, cultural practices, and soil types, no step-by-step weed control system has been devised. Using a combination of herbicide treatment, mechanical weed control, and mulching—capitalizing on the best features of each of these practices—is the best approach to weed control in the home garden. Precautions. Always follow the manufacturer’s directions printed on the label for handling and use. Store and discard containers properly.

APPLE AND PEAR Apple and pear trees are subject to serious damage from pests and, as a result, a preventive spray program is needed. The following practices will improve the effectiveness of the pesticides and may lessen the need for sprays. • Plant disease-resistant varieties. This method of disease control is especially important for fire blight, where chemical control options are limited. Varieties resistant to cedar-apple rust, scab and powdery mildew are also available and will potentially reduce the need for sprays. • Rake and destroy leaves in the fall, if apple scab or pear leaf spot are problems. The fungi that cause these diseases can survive through the winter in infected leaves. • For cedar-apple rust control, the spores that infect apples come from cedar trees. Elimination of the source of spores (cedar trees) is effective, but not always possible. Where cedars are part of an established landscape, remove and destroy all galls caused by the rust fungus on cedars in the late fall. Inspect the cedars again in the early spring during or just after a rain when the orange, gelatinous fungus growth from any remaining galls is highly visible, and remove them. Table 1. Disease Management for Home Orchards Time of Application

Pest Controlled

Delayed dormant: When leaves start to protrude from buds Bud break: From ½ inch long Scab, powdery mildew, green leaves to tight cluster (when rust, apple rot blossom buds are just visible) Pink: Just before blooms open Scab, powdery mildew, rust, apple rot, fire blight Bloom: Begin at early bloom, repeat at 3 to 5 day intervals Petal fall: When most of the blooms have fallen First cover: 7 to 10 days after petal fall spray Remaining covers: Apply at 14-day intervals until harvest restriction date

• Pruning trees according to recommendations improves control of all above-ground diseases. In well-pruned trees, air circulation and sunlight penetration are improved. This helps control diseases by promoting rapid drying after rains and dew. Penetration of sprays into the canopy is also better if the trees are well pruned. • Prune out and destroy all dead or diseased shoots and limbs during the dormant season. This helps reduce fire blight, fruit rots, and certain leaf spots, as the organisms that cause these diseases can survive through the winter in the wood. Removing mummified (dark, shriveled, dry) fruit helps prevent the overwintering of the fruit rot organisms. • Pruning out fire blight-affected shoots and blossom clusters during the growing season is warranted if it is done just as symptoms are appearing. Prune during dry weather and sterilize tools between cuts. See ANR–0542 for more information on control of fire blight.

PEAR The only disease control products that can be used on pear are copper, sulfur, and Streptomycin sulfate. Copper and sulfur can be used for leaf spot, scab, and other diseases as directed on the label. Both copper and sulfur can injure pears. So read

the label carefully. Streptomycin sulfate can be used for fire blight under the apple schedule listed above.

PEACH AND PLUM Peach, plum, and other stone fruits are commonly affected by several insect and disease problems each year and a spray program is needed for successful fruit production. The following sanitation and cultural practices will improve the chances of success and may lessen the need for sprays. • Prune trees according to recommendations, to allow better air circulation and sunlight penetration. Pruning helps control diseases by promoting rapid drying after rains and dew. Penetration of sprays into the canopy is also better if the trees are well pruned. • Remove and discard old mummified fruit left hanging in the tree or on the ground. These mummified fruit are the overwintering structures of the brown rot fungus. See ANR 1182, “Brown Rot of Stone Fruit,” for more information on brown rot.

• Control of black knot of plum is dependent on removal of the knots before they begin to produce spores. In late winter, prune out and destroy these rough, black swellings or galls that develop on twigs and branches. See ANR 1055, “Black Knot on Plum and Cherry Trees,” for more information on black knot. • Avoid planting peach varieties that are highly susceptible to bacterial spot as there are few options for control of this disease. Examples of highly susceptible cultivars are Elberta, Halehaven, Rio-Oso-Gem, O-Henry, Cresthaven, and Sunhigh.

BLUEBERRY Rabbiteye blueberries are relatively free of insects and diseases. As a rule, blueberry plants require the least amount of pesticides of all fruit crops. Treatments can usually be made on an as-needed basis. If diseases have been a problem in the planting in past years, captan can be used at 7- to 10-day

intervals from bud break to harvest. If mummy berry disease has been a problem, rake the area beneath and around plants to collect or bury any mummified fruits from the previous year’s crop. This will help reduce the incidence of mummyberry. To reduce dieback diseases, prune out and destroy dead twigs and branches.

BLACKBERRY An intensive spray program is generally not needed. For blackberry, fungicide and insecticide sprays can often be applied on an as-needed basis. The following sanitation practices will reduce the need for pesticide sprays. • To reduce the source of pests, remove and destroy nearby wild blackberries. • Remove and destroy fruiting canes immediately after harvest. • Promote rapid drying and good air circulation within the canopy by controlling weeds and keeping the plants properly thinned. • Pick berries often during the harvest period to minimize the amount of overripe fruit. This will reduce problems with berry rots, sap beetles, wasps, and fruit flies.

• Plants infected with orange rust should be promptly dug up and removed or destroyed as soon as symptoms appear in spring. Symptoms of orange rust include willowy growth of new shoots and the presence of orange spore pustules on the undersides of the leaves. • To control the spread of rosette, remove and destroy infected canes before blooms begin to open. Rosette is recognized by the presence of clusters of stems on fruiting canes, producing a bunchy appearance. Flower sepals are extended and pinkish in color on plant with rosette.

GRAPES Most grape plantings, except muscadine, will require a preventative schedule of fungicide and insecticide sprays for successful production. Pests like black rot can completely destroy a crop of fruit. However, the following sanitation and cultural practices will reduce the need for pesticides. • Keep vines well pruned according to recommendations, to prevent overgrowth of vines and a dense canopy. Pruning improves air circulation and sunlight penetration, thus promoting rapid drying after rains and dew. Penetration of sprays into a foliar canopy is also better when vines are pruned.

• Fruit rot organisms of grapes can survive through the winter on old vines and dried fruit on the vines and ground. Remove and destroy mummified fruit (shriveled, dry, raisinlike) on vines as well as those on the ground. Also, prune and destroy vines with stem cankers as they are also a site for these fungi to survive through the winter.


Dormant: After vines are pruned and before buds break.

STRAWBERRY Many times, strawberry plants can be grown almost diseasefree without spraying. Weather conditions, however, can cause diseases to develop and spread, and spraying will be necessary. The following practices will improve the effectiveness of the pesticides and may lessen the need for sprays. • Dormant season sanitation will reduce disease pressure most years. Strawberry leaf spots and Botrytis blight pathogens

can survive through the winter on old leaves and debris on the bed. Clipping old leaves, raking, and composting or destroying aids in disease control. • Control weeds during the growing season. Weeds increase disease by reducing light penetration and air circulation, and they intercept pesticide sprays. Weeds can also harbor insects and mite problems.

Subterranean Termites IPM-1316


SUBTERRANEAN TERMITE CONTROL PRODUCTS A survey conducted by the Alabama Cooperative Extension System in early 2004 shows that 75 percent of the Alabama pest control companies consider termite control the most difficult and the highest cost service. About 65 percent rank termite service as being the most profitable, and 90 percent rate it as being the most risky and the greatest liability. Termite control of homes requires special skills, specialized equipment, and knowledge about both termite biology and building construction. Therefore, termite treatment is better left for certified pest control professionals. A possible exception would be if a mailbox post, sandbox, or other small wooden object not attached to the house was infested. There are more termite-treatment options available today than ever before. In general, there are five types of treatment programs: liquid termiticides, bait systems, wood preservatives, mechanical barriers, and biological termiticides. The success of these programs depends on professional workmanship. Although none of the products contain restricted pesticides, most of the products are for professional use. “Do-it-yourself” products, sold to homeowners at retail stores or bought over the Internet, will seldom eradicate an existing termite problem. This publication attempts to explain the pros and cons of each type of treatment program and is a supplement to Extension publication ANR-1022, “IPM Tactics for Subterranean Termite Control.” Liquid Termiticides There are two groups of liquid termiticides: new nonrepellent termiticides and repellent termiticides. See Tables 1 and 7 for more information. Application. Liquid termiticides can be used for pre- and post-construction treatments to create a chemical barrier in the ground around your house and potential entry points. The chemical barrier either kills or turns termites away. Termiticide users are required by LAW to comply with the instructions and directions for use in product labeling. Advantages: • Provide immediate protection for the structure • Require less maintenance • Repellent termiticides are the most inexpensive treatment. • Non-repellent termiticides are not detectable by termites, so termites tunnel in and are killed. Disadvantages: • Require drilling/injection of slabs and other masonry components and trenching/drenching of soil

• Require equipment for mixing, drilling, and injecting • Are not recommended for application within 50 feet of a body of water, well or cistern • Repellent termiticides may have an odor associated with their use. • Gaps in repellent termiticide applications may later provide access to termites. Bait Systems See Tables 2 and 7 for more information. Application. Maintaining bait systems is an on-going process involving monitoring, baiting, and inspection. It begins with plastic stations, which are placed in the ground around the structure (10 to 20 feet apart). Inside the stations are either monitoring food sources or baits. These stations are inspected monthly or quarterly, and when termites are found inside a station, the monitoring food source is replaced with bait. Baited stations can also be installed aboveground in the path of termite tunnels or over termite-infested wood. Termites consume the bait and communicate the source of the bait to colony members, thus killing the termite colony. Baits contain either an insect growth regulator or a slow-acting toxicant. Bait systems are recommend for postconstruction treatment only. Advantages: • Are environmentally friendly and extremely low toxicity to humans and pets • Can be used in situations where the infested structure is within 50 feet of a well or 100 feet of a body of water • Are less intrusive: no drilling/trenching is required and installation is easy. Disadvantages: • With no means of attracting termites into the monitors, bait systems may take longer than other treatments to control termites. • May cost more because baits must be inspected and serviced at intervals for on-going prevention and control of termite colonies. • Require high maintenance • In some cases, complementary liquid treatment may be needed. Wood Preservatives See Tables 3 and 7 for more information. Application. Liquid wood preservatives are applied on unfinished wood to prevent or kill termites and should be used as supplemental application in conjunction with liquid termiticides or baits. In addition to the chemicals listed here, some nonrepellent termiticides are also labeled for wood treatment.

Advantages: • Are low in mammalian toxicity • Are less expensive • Can last for decades unless exposed to constant rewetting Disadvantages: • Cannot be used on weather-exposed outdoor wood due to leaching problem • May not penetrate to the center of the wood beam Biological Termiticides See Tables 4 and 7 for more information. Application. Biological termiticies are formulated either as wettable powder (fungus) or in a water dispersible medium (nematodes) and can be used for spray or injection in the same way as liquid termiticide. Dosage is 100 ppm per gallon of water per linear foot of treated area. Advantages: • Are safe for people, plants, and non-targeted organisms

Disadvantages: • Have to be applied when temperature is between 50 and 80oF • The solution must be agitated during application. Termite-Proof Materials See Table 5 for more information. Application. Two types of termite-proof durable material are available. One is pesticide free and made of durable materials that work as mechanical barrier. The other contains a termiticide between durable polymer layers and kills upon being contacted or chewed on. Termite-proof material is installed prior to pouring the concrete slab and positioned around utility conduits (plumbing, electrical pipes and wires, and bath trap areas). Advantages: • Are environmentally responsible, user friendly • Provide protection even before occupancy • Are durable Disadvantages: • Can be put in place pre-construction only • Should be used to complement liquid or bait treatments

Under pressure from EPA, Dow Chemical pulled Dursban from retail shelves at the end of 2001, but continues selling it for termite pretreatments in new home construction. Until its use as a termiticide is banned in 2006 for new homes and buildings, it is still being used.
