The Enlist One and Enlist Duo labels that were approved in January had several new restrictions, including the prohibition of use in 10 counties in Kansas (Chautauqua, Cherokee, Cowley, Elk, Greenwood, Labette, Montgomery, Neosho, Wilson, and Woodson). Amended supplemental labels were approved on March 29 to allow the use of Enlist One and Enlist Duo in these counties.
Enlist One and Enlist Duo are the only 2,4-D formulations approved for over-the-top herbicide application to Enlist E3 soybean and cotton. Some of the other restrictions that were new to the 2022 labels include using runoff mitigation measures to reach the number of credits needed for your soil type, and application cutoffs of R1 in soybean and first white bloom in cotton.
