FMC Corporation has issued FIFRA section 2(ee) labels for Pounce 1.5G and Pounce 3.2EC. These labels can be used in all states where the crop and pest(s) exist and where 2(ee) recommendations are recognized. Basically, a section 2(ee) registration allows use of a product to control a pest in a manner not specified on the federal label, as long as the product is labeled for that site (e.g., crop) and the maximum registered rate of application is not exceeded. FMC has issued a 2(ee) label for Pounce 1.5G to control wireworms, seedcorn maggots, and sod webworms in field corn. The rate of application is 6.7 to 13.3 pounds of product per acre or 8 to 16 ounces of product per 1,000 linear feet of row, applied at planting directly into the seed furrow. The higher-labeled rate is recommended for heavy wireworm infestations. The 2(ee) label for Pounce 3.2EC is also for control of wireworms, seedcorn maggots, and sod webworms in field corn. The rate of application is 4 to 8 ounces of product per acre or 0.3 to 0.6 ounces per 1,000 linear feet of row, applied at planting directly into the seed furrow. Again, the higher labeled rate of application is recommended for heavy wireworm infestations. However, FMC personnel recommend that a planter-box seed treatment be considered as a first choice (I assume for wireworms and seedcorn maggots), and Pounce 1.5G or Pounce 3.2EC should be considered by those growers who do not like to use seed treatments.
Although 2(ee) labels are recognized in Illinois, we do not know whether Pounce is effective against the intended target pests in the manner indicated on the labels; we have seen no efficacy data. In other words, we urge caution before you decide to go this route for control of wireworms, seedcorn maggots, and sod webworms. Alternatives for control of these pests exist, and the efficacy of some of the alternatives is known. We will search for efficacy data regarding the claims on FMC's 2(ee) labels and offer our insight accordingly.--Kevin Steffey, Mike Gray
