New Enlist One and Enlist Duo Herbicide Labels Approved

Jan 27, 2022

By Sarah Lancaster

On January 11, the EPA renewed labels for Enlist One and Enlist Duo for seven years. These are the only 2,4-D formulations approved for over-the-top herbicide application to Enlist E3 soybean and Enlist cotton. The labels come with some additional restrictions compared to the previous labels. These additional restrictions are summarized below.

Use runoff mitigation measures to reach the number of credits needed for your soil type. Runoff mitigation measures are listed in Table 1. Fields with sand, loamy sand, sandy loam or sandy clay loam soil must accumulate 4 credits. Fields with silt loam, loam, clay loam, silty clay loam, sandy clay, silty clay, or clay soil must accumulate 6 credits.
There are ten counties in Kansas where the use of Enlist herbicides has been prohibited by the EPA due to an updated Endangered Species Act risk assessment. These ten Kansas counties are: Chautauqua, Cherokee, Cowley, Elk, Greenwood, Labette, Montgomery, Neosho, Wilson, and Woodson. Corteva representatives are continuing to work to establish mitigation measures for Enlist use in these counties. Additional information will be made available as soon as possible.
Products may be applied through R1 in soybean and first white bloom in cotton.
The list of approved nozzles has been expanded. Updated list of qualified nozzles will be available at Enlist.com. Please note there may be a slight delay in website updates.

Video: What Happens When Pigs Adapt to High Soybean Meal Diets? - Gustavo Lima

In this special rerun episode of The Swine Nutrition Blackbelt Podcast, Gustavo Lima, PhD candidate in Animal Science at Iowa State University, discusses how grow-finish pigs respond to high soybean meal diets. He explains the initial drop in feed intake, changes in backfat, later adaptation, energy efficiency, amino acid utilization, and the rise in nitrogen excretion at higher inclusion levels.

“Once they got adapted to the diet, they can handle higher levels of inclusion of soybean meal.”
