EPA lifts previous restrictions on Enlist One® & Enlist Duo® herbicides in 128 counties

March 2022 

In January, the U.S. Environmental Protection Agency’s (EPA) relabeling of Enlist One® and Enlist Duo® herbicides for the 2022 growing season was good news for most soybean growers. At that time, there were a small number of counties where the herbicides could not be relabeled until additional endangered species risk assessment data could be obtained.

On Tuesday, however, Corteva Agriscience announced that 128 of those counties initially restricted now have full access to the Enlist herbicides.

The EPA issued updated supplemental labels for the herbicides that remove geographic restrictions for two listed species, the American burying beetle and the eastern massasauga rattlesnake.

Notably, the Enlist herbicides were granted a seven-year amended registration and are the first products to complete the EPA's new Endangered Species Act protection risk assessment process.

Updated supplemental labels
The updated supplemental labels remove geographic restrictions for Enlist One and Enlist Duo herbicides in 128 counties where the American burying beetle is found, and six counties where Enlist Duo was restricted due to the eastern massasauga rattlesnake. 

Counties that have now been reinstated include:

  • Arkansas: Crawford, Franklin, Johnson, Little River, Logan, Montgomery, Polk, Scott, Sebastian, Sevier and Yell.
  • Kansas: Chautauqua, Cherokee, Cowley, Elk, Greenwood, Labette, Montgomery, Neosho, Wilson and Woodson.
