WEED CONTROL

PESTICIDE DRIFT/WEED CONTROL

The U.S. EPA tolerance levels are the best scientific information available, but you or your customers may not trust that information completely, and if your customers have heard of the drift problem, selling affected produce may damage your farm's reputation. Concentrations detected by analyzing selected plant tissues, usually leaves, may have little relationship to the concentrations of herbicide occurring in the harvested portion of the plant, often the fruit. Because there are so many unknowns, it is advisable to not consume the vegetable when visible herbicide injury occurs to the plant. Herbicide drift can kill flowers and damage fruit and leaves. The damage makes the harvested vegetable unsightly and may affect storage life and taste. If you are interested in harvesting some undamaged vegetables from a field with areas having drift damage, get as much information as possible. What herbicide(s) drifted? Many herbicides that commonly cause drift injury are absorbed by the leaves and translocate to the growing points, fruit, and seed where they concentrate. Some herbicides such as 2,4-D degrade in plants, others such as glyphosate degrade only slightly in plant tissues. Over time the herbicide concentration in the plant may be diluted due to plant growth and herbicide loss in dead shoot and root tissue. Having the vegetables analyzed for herbicide residue is critical to making an informed decision in herbicide drift situations. Several private laboratories will analyze plant tissues for herbicide residues for a fee; that fee can be several hundred dollars per herbicide per sample. Talk to the applicator who caused the drift problem; they may be willing to pay for the analysis. Some manufacturers will analyze plant tissues for their products. For state Departments of Agriculture to be involved you usually must file a formal written complaint alleging herbicide misapplication. Contact your State Department of Agriculture as soon as possible after discovering herbicide injury. For example, in Pennsylvania, pesticide misuse complaints are filed with the Pennsylvania Department of Agriculture’s Bureau of Plant Industry: http://goo.gl/o9zY9. In addition, samples for residue analysis must be collected correctly and in a timely manner for it to be useful for you in the decision making process. If the harvested part is present, collect that tissue. If fruit are not present, then collect samples of recently formed leaves and the shoot tips. Translocated herbicides will concentrate in those tissues. Ask that fruit samples be collected later to help you in deciding whether or not to sell or consume the fruit. Make sure that samples are collected from the crop plants showing injury and as close as possible to the site of herbicide application. What does information herbicide residue concentrations tell you? Sometimes it may not tell you much. Obviously the lower the contaminating herbicide concentration, the better, and a concentration below an established tolerance is better than one above, but there are no clear-cut answers. The herbicide may be absent from the parts you wish to harvest and eat, or the herbicide concentration may be below the limits of detection for the equipment or procedure being used. Another possibility is that your sampling procedure was not effective enough to find tissues with residues, or the herbicide may have degraded between the time of the drift and when you sampled (or during sampling, handling, shipping, or

storage). Be conservative in how you interpret the residue information. The scientific literature suggests that for herbicide residues from drift and subsequent absorption into vegetables, acute poisoning effects are very unlikely. Questions about the possible chronic effects (including cancer, the endpoint that is always debated in questions about pesticide safety) from multiple exposures from repeated incidents of herbicide drift along with many other routes of exposure remain the subject of research.

What Should You Do With Fruit and Vegetables After Pesticide Drift? (J. Masiunas, University of Illinois) A common question after a vegetable field is damaged by pesticide drift is whether or not it is "safe" to harvest and consume the produce. This is a very difficult question to answer. Re-entry time and worker protection information on the pesticide label will provide guidance on when the field can be re-entered, but it provides no information about the residue that might be on or within the produce. To answer conclusively the question about whether or not it is "safe" to harvest and consume the produce requires knowledge of the pesticide involved, the amount of residues within the plant, the health effects of the pesticide, how the harvested part of the plant has changed, and laws regulating pesticides.

WEED CONTROL Effective weed control requires a program that emphasizes prevention by combining crop rotation with mechanical and chemical control methods.

Postharvest Weed Control Weed seed populations in the soil should be kept to a minimum by preventing weeds from producing seed in and around vegetable fields. Destroy all weeds immediately after a crop is harvested. Consider control measures after harvest, but before the first frost, for the following weeds: 1.

To suppress or control bitter nightshade, Canada thistle, field bindweed, hemp dogbane, horsenettle, or pokeweed, use a tank-mix of 1 quart Banvel plus 1 quart 2,4D amine in 10 to 20 gallons of water per acre. Apply in late summer or early fall to healthy weed foliage for maximum effectiveness (Note. Delay seeding of winter cover crop 3 weeks for each pint per acre of Banvel used). See herbicide labels for optimum treatment time for each weed.

2.

To suppress brambles, horseradish (volunteer), horsenettle, milkweed, poison ivy, or sow thistle, tank-mix 1.5 lb acid equivalent glyphosate, using one of many labeled glyphosate products, plus 1 pint Banvel (see note above) in 10 to 20 gallons of water per acre. Use 1 to 2 quarts surfactant (50 to 100 percent active) per 100 gallons of spray mixture. Apply in late summer or early fall to healthy weed foliage for maximum effectiveness. See

E7

WEED CONTROL

herbicide labels for optimum treatment time for each weed. 3.

To control johnsongrass or quackgrass, apply 0.75 to 1.1 lb acid equivalent glyphosate, using one of many labeled glyphosate products, in 5 to 10 gallons of water per acre. Delay tillage until 4 to 7 days after application. Apply in late summer or early fall to healthy weed foliage for maximum effectiveness.

To control Bermudagrass, apply the maximum labeled rate of Poast, Fusilade 2000, or clethodim (Select, Select Max, or Arrow) in late spring after the weed has begun to grow. Work toward planning your crops and crop rotation to be able to treat monthly with one of the above listed products through late summer without conflicting with the Preharvest Interval (PHI) of the crop(s) being grown.

To control yellow nutsedge foliage and suppress nutlet formation, spray with a labeled glyphosate product after flowers (seedheads) appear, but before foliage dies. Use 2.25 lb acid equivalent glyphosate in 10 to 20 gallons of water per acre. Expect only partial control of yellow nutsedge the first year after initiating the program. Plant a crop the following spring with registered herbicides recommended for yellow nutsedge control (see Table E-3). Effective yellow nutsedge control can be achieved by repeating the application for several consecutive years.

WEED CONTROL/PLANTING RESTRICTIONS

Table E-5. Crop Rotation Planting Restrictions—Months After Herbicide Application Until Planting New Crop1 Table E-4 summarizes the crop rotation constrictions after certain herbicide applications have been made. Example: Devrinol was applied to tomatoes this year. You must delay planting sweet corn in the field for 12 months after application of Devrinol. Consult the label for a different time interval if two or more of these materials are applied in the same season. This table is not a substitute for the label!

WEED CONTROL/HERBICIDE SITE OF ACTION FOR REDUCING THE RISK OF DEVELOPING HERBICIDE-RESISTANT WEEDS

Table E-8. Herbicide Site of Action for Reducing the Risk of Developing Herbicide-resistant Weeds Reducing the risk for developing herbicide-resistant weed populations requires incorporating a number of guidelines in managing your fields. These guidelines include:

 Spray only when necessary  Use alternative methods of control whenever possible such as mechanical cultivation or delayed planting (row crops),     

mowing (forage crops), and using weed-free crop seeds Rotate crops and their accompanying herbicides’ site of action Limit number of applications of herbicide(s) with same site of action in a given growing season Use mixtures or sequential herbicide treatments having different sites of action that will control the weeds of concern Scout fields after herbicide application to detect weed escapes or shifts Clean equipment before leaving fields infested with or suspected to have resistant weeds

Rotating herbicides with differing sites of action is important for minimizing the risk of developing herbicide-resistant weeds. However, information on herbicide site of action is often not printed on herbicide labels and thus is difficult to obtain. The following tables are designed to assist with herbicide selection based on herbicide site of action. Below (Table E-7A) is a list of important herbicide groups for agronomic crops grown in the Mid-Atlantic region. To reduce the risk of developing herbicide resistant weeds, avoid repeated use of herbicides with the same site of action. Note that more than one herbicide family may have the same site of action. A list of common pre-package herbicide mixture and their components is contained in Table E-7B. Be sure to know the site of action for all the herbicides included in the pre-package mixture.
