On Tuesday, January 11th, the U.S. Environmental Protection Agency (EPA) announced that it has issued seven-year registrations for two herbicide products registered by Corteva Agriscience (Enlist Duo and Enlist One). According to EPA, the new product labels incorporate robust control measures to protect non-target plants and animals, meet Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) standards and comply with the Endangered Species Act (ESA).
Enlist Duo and Enlist One are herbicides used to control weeds in conventional and genetically-modified corn, cotton, and soybean crops. Due to EPA considerations related to the ESA, there are certain counties in Western Arkansas that will be prohibited from using the registered products (details provided below from UofA weed scientist Tommy Butts).
To view the final registration for Enlist Duo and Enlist One, go to docket EPA-HQ-OPP-2021-0957
