EPA lifts ban on 134 previously restricted counties
On Jan. 11, 2022, EPA issued seven-year registrations for Enlist Duo and Enlist One. In March 2022, EPA approved a registration amendment to allow use of the products in 136 additional counties. The product registrations will be in effect for the 2022 growing season. Both products were set to expire in January if the Agency had not renewed their registrations.
The new registrations include additional protective measures and restrictions for applicators. New measures include:
Prohibiting Enlist product application when rainfall is expected to occur within 48 hours, and when soil can no longer absorb water.
Prohibiting irrigation that would result in runoff within 48 hours of application of the Enlist products.
A timing restriction for Enlist product application when soybean and cotton crops are in bloom to reduce risk to insect pollinators.
Mitigation credits
Additionally, users of Enlist One and Enlist Duo must earn credits based on the hydrologic soil groups of their fields. Soils are classified in four different subgroups. For Hydrologic Soil Groups A and B, applicators must earn four credits, while applicators managing land in Hydrologic Soil Groups C and D must earn six credits.
Users can choose from a list of mitigation measures to achieve the appropriate number of points needed. For example, planting cover crops earns two credits. The mitigation measures generally function by reducing potential for runoff. They include:
Contour buffer strips, terracing or vegetative barrier
Cover crops
Field borders
Conservation Tillage (no-till, strip-till, mulch-till)
Contour farming or contour strip cropping
Reduced number of applications of the products per year
An announcement from EPA’s Office of Chemical Safety and Pollution Prevention, requiring users to select from a list of runoff reduction measures will reduce detrimental effects of runoff while providing applicators and land managers with flexibility.
EPA will also be prohibiting the use of Enlist Duo and Enlist One in counties where they identified risks to plant and animal species.
The federal label allows use of Enlist One and Enlist Duo in the following states: Alabama, Arkansas, Arizona, Colorado, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Jersey, New Mexico, New York, North Carolina, North Dakota, Oklahoma, Ohio, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Virginia, West Virginia and Wisconsin with some restrictions.
However, EPA has prohibited the use of Enlist One and Enlist Duo in counties where EPA expects the use of Enlist products would likely affect or jeopardize on-field listed animal species that use corn, cotton or soybean fields for diet and/or habitat. EPA recommends that users read page 16 of the new Enlist One label and page 16 of the new Enlist Duo label to see which counties remain prohibited.
