EPA lifts 2022 Enlist One, Enlist Duo herbicide restrictions in 134 counties

Farmers in these formerly restricted counties due to an Endangered Species Act process may now access Enlist herbicides for 2022.

Good news for some farmers who were shut out of applying Enlist One and Enlist Duo herbicides for 2022: They may now access these herbicides for the upcoming growing season. 

The Environmental Protections Agency has issued updated supplemental labels for the herbicides that remove geographic restrictions for two listed species, the American burying beetle and the eastern massasauga rattlesnake. Enlist herbicides were granted a seven-year amended registration in January and are the first products to complete the EPA’s new Endangered Species Act (ESA) Protection risk assessment process.

However, counties still remain where farmers cannot apply the Enlist products due to the ESA protection risk assessment process. Approximately 40 counties located in Arizona, Colorado, Florida, Tennessee, and south-central Texas have prohibitions on both Enlist One and Enlist Duo for a listed species other than American burying beetle or the eastern massasauga rattlesnake, says a Corteva spokesperson.

“Corteva Agriscience is working on behalf of our customers to see as many labeled-off counties reinstated as possible while still protecting listed species and their habitats,” said Susanne Wasson, president, crop protection business platform for Corteva Agriscience, in a news release. “American burying beetle and eastern massasauga rattlesnake counties were prioritized because they represent the majority of restricted acres and getting them back on the label allows more growers access to this critical weed control technology for 2022.”

Supplemental Label Specifics

The updated supplemental labels remove geographic restrictions for Enlist One and Enlist Duo herbicides in 128 counties where American burying beetle is found, as well as six counties where Enlist Duo was restricted due to the eastern massasauga rattlesnake. Updated usage area maps and supplemental labels will be available here.

“Corteva Agriscience is continuing to conduct studies and provide additional data to EPA to support the removal of further geographic label restrictions where feasible,” said Cynthia Ericson, vice president, U.S. marketing for Corteva Agriscience, in a news release.

The Enlist weed control system includes Enlist herbicides, Enlist Ahead, Enlist E3 soybeans, Enlist cotton, and Enlist corn. The system offers multiple herbicide sites of action and is centered around 2,4-D choline with Colex-D technology.

Corteva officials say system benefits include:

  • Near-zero volatility
  • Reduced potential for off-target movement and physical drift
  • Improved handling characteristics when applied pursuant to label instructions
  • Tolerance from Enlist cotton and Enlist E3 soybean crops to 2,4-D choline (Group 4), glufosinate (Group 10) and glyphosate (Group 9)

Officials for Corteva say the company will also continue grower education efforts, including label changes, through the Enlist Ahead management resource, which informs growers, distributors, retailers, and applicators about proper use. The Enlist Ahead program helps customers with on-target applications and sound weed management practices for successful, sustainable use of the Enlist weed control system.
