This section of the bulletin is intended to help growers manage insect populations with methods effective for Mid-Atlantic conditions. The recommendations deal primarily with chemical control; however, the use of insecticides on field crops should be considered supplementary to cultural and biological control methods. Except where otherwise indicated, the insecticides listed are for use as foliar sprays. Common insecticide names are followed by trade names in parentheses, followed by specific formulations. Rates are usually given in pounds of active ingredient per acre and in pounds of the formulated product per acre. Safety, price, availability, effectiveness, and other factors should be considered when narrowing the list to the product that is chosen for use. The list is revised annually and is for use during the current calendar year only. The list also is subject to annual review. Contact your county Extension educator for information about the status of a particular insecticide.
Time limits: Days to harvest refers to the legal number of days before harvest that insecticides can be applied safely to avoid excessive residues on the harvest crop. Read all labels carefully because the time limits may vary depending upon the rate used and the final use of the harvested crop. If not specified under Remarks, the days-to-harvest restriction applies regardless of whether the harvest is for forage or grain. This time period in no way signifies how long the insecticide will remain active in controlling insects.
Information in this section is not a substitute for the product label-always read the label before use.
