Corteva Agriscience announced that the U.S. Environmental Protection Agency (EPA) has completed the registration amendment process for Enlist One® and Enlist Duo® herbicides, giving farmers certainty in product availability as they complete their 2022 seed planting and crop protection plans. Enlist herbicides received a seven-year registration through January 11, 2029. The Enlist® weed control system includes Enlist herbicides, Enlist™ Ahead, Enlist E3® soybeans, Enlist® cotton and Enlist corn.

The comprehensive system offers multiple herbicide modes of action to control tough weeds and is centered around 2,4-D choline with Colex-D® technology, which provides key benefits including near-zero volatility, reduced potential for off-target movement and physical drift, and improved handling characteristics. Further, Enlist cotton and Enlist E3 soybean crops are tolerant to three herbicide modes of action, 2,4-D, glufosinate and glyphosate, allowing for a robust integrated weed management program to tackle herbicide resistance and improve the sustainability of farmers' weed control practices. The Enlist herbicide registration amendment process included EPA conducting updated data analyses and initiating appropriate agency consultations to help confirm Enlist herbicides continue to comply with the Endangered Species Act (ESA), and the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA).

As part of that process, EPA updated its ecological and ESA risk assessments, resulting in the addition of targeted risk mitigation measures to the Enlist herbicide labels. These updates will help ensure that use of Enlist herbicides in accordance with the label will help protect endangered species and their habitats while also allowing growers to continue to capture the benefits of the Enlist® weed control system.
