Enlist corn and Enlist soybean producers in 32 Nebraska counties will be restricted on the use of two herbicides, Enlist ONE and Enlist DUO, in the 2022 growing season after the United States Environmental Protection Agency renews registrations.

Environmental Protection Agency (EPA) issued seven-year registrations for Enlist Duo (2,4-D Choline + Glyphosate) and Enlist One (2,4-D Choline). Both herbicides are being applied in Enlist Soybean and Enlist Corn primarily for control of glyphosate-resistant marestail, Palmer amaranth and waterhemp in Nebraska. Based on these findings, EPA is requiring the implementation of protective measures as a condition of the product registrations.

• No application permitted after soybean is in bloom and might attract pollinators.
• EPA will also prohibit the use of Enlist Duo and Enlist One in counties where EPA identified risks to on-field listed species that use corn, cotton or soybean fields for diet and/or habitat. The counties where use will be prohibited by these new measures represents approximately 3% of corn acres, 8% of cotton acres, and 2% of soybean acres nationally.

• 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 herbicide products.
• Requiring users to select from a list of runoff reduction measures to reduce 2,4-D and glyphosate concentrations in runoff, while also providing users with flexibility.
• Minimizing Enlist product application when soybean and cotton crops are in bloom to reduce risks to insect pollinators, such as honey bees.
• Requiring the registrant to develop and provide mandatory education and training materials that emphasize the importance of pollinators and pollinator habitat for species including, but not exclusive to, monarch butterflies.
• EPA will also be prohibiting the use of Enlist Duo and Enlist One in counties where EPA identified risks to on-field listed species that use corn, cotton or soybean fields for diet and/or habitat.
• EPA does not expect this measure to disrupt the use of Enlist products for most American farmers — the counties where use will be prohibited by these new measures represents approximately 3% of corn acres, 8% of cotton acres, and 2% of soybean acres nationally.

• Downwind 30-foot infield buffer required to protect sensitive areas. 

In Nebraska, the following counties will no longer be able to utilize Enlist ONE and Enlist DUO:

• Antelope, Blaine, Boone, Boyd, Brown, Cherry, Custer, Dawson, Frontier, Furnas, Garfield, Gosper, Greeley, Hayes, Holt, Hooker, Howard, Keya Paha, Knox, Lincoln, Logan, Loup, McPherson, Merrick, Nance, Phelps, Red Willow, Rock, Sherman, Thomas, Valley and Wheeler.
• According to USDA crop production data, these counties planted over 1.02 million acres of soybean in 2020. We will continue to provide updates as they become available.
