FIFRA Section 2(ee) Recommendations for Insecticides

April 5, 2002
Section 2(ee) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) allows for uses of a pesticide that are not inconsistent with its labeling. For example, a pesticide can be applied against any target pest not specified on the label if the application is to the crop, animal, or site specified on the label. Consequently, some companies issue Section 2(ee) recommendations for products to control pests in crops for which the products are already registered. These recommendations allow companies to offer quick "updates" before the federal label is amended.

DuPont has issued a Section 2(ee) recommendation for Asana XL for control of soybean aphid in soybean in the states of Colorado, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, Pennsylvania, South Dakota, and Wisconsin. The rate of application is 5.8 to 9.6 ounces per acre. Restrictions: do not feed or graze livestock on treated fields; do not apply more than 0.2 pound of active ingredient per acre per season; do not apply within 21 days of harvest. In insecticide efficacy trials throughout the Midwest, Asana has worked as well as other pyrethroids for control of soybean aphids.

Syngenta has issued a Section 2(ee) recommendation for Warrior for suppression and/or control of wireworm, cutworm spp., seedcorn maggot, white grub spp., western corn rootworm, and northern corn rootworm in corn in Colorado, Illinois, Indiana, Kentucky, Missouri, Kansas, Nebraska, Minnesota, South Dakota, Wisconsin, Michigan, Pennsylvania, Delaware, and Iowa only. The rates of application are 1.92 ounces per acre for wireworms; 3.2 ounces per acre for cutworm species and seedcorn maggot; and 3.84 ounces per acre for white grub species, western corn rootworm, and northern corn rootworm. Warrior can be applied at planting as an in-furrow or T-band treatment. Refer to the federal label for restrictions for use.

The word "suppression" for the 2(ee) recommendation for Warrior applies to cutworms, white grubs, and corn rootworms. We are not excited about the use of this term and urge caution with any product labeled for suppression of an insect pest. Results from insecticide efficacy trials have shown that Warrior is not effective for controlling corn rootworms.--Kevin Steffey
