EPA Sets Comment Period for Enlist Duo Label Expansion

The U.S. Environmental Protection Agency (EPA) has set a public comment period for the proposed label amendment for Enlist Duo, which would allow use on Enlist cotton and extend product use on all labeled Enlist crops to 19 other states.

The proposal to amend the registration for Enlist Duo is described in detail on the EPA website.

Public comments on the proposal must be submitted by December 1, 2016, to EPA docket # EPA-HQ-OPP-2016-0594 at the Regulations.gov website. After the comment period closes, EPA will review all of the input and reach a final decision, which is expected in early 2017.

Enlist Duo was first registered in 2014 for use in Enlist corn and soybean crops in six states, and later in nine additional states. EPA has completed its analysis of all the scientific studies and is proposing to amend the registration of Enlist Duo for use on Enlist cotton in the existing 15 states, as well as expanding the use on registered crops in 19 other states.

According to EPA documents, weed resistance continues to be a serious problem for farmers, and Enlist Duo would provide an additional tool to reduce the spread of glyphosate-resistant weeds. But EPA is proposing special requirements to address concerns about potential increased weed resistance to 2,4-D, including continual surveying and reporting to EPA, grower education, and remedial programs.

In addition, the registration will expire in five years, allowing EPA to revisit the issue of resistance. The label will also contain resistance management information consistent with the Weed Science Society of America’s Best Management Practices.

Enlist Duo is currently registered for use on Enlist corn and soybean crops in Arkansas, Illinois, Indiana, Iowa, Kansas, Louisiana, Minnesota, Mississippi, Missouri, Nebraska, North Dakota, Oklahoma, Ohio, South Dakota and Wisconsin.

The proposed label modification would allow use of Enlist Duo on Enlist cotton in the currently labeled states and expand the use for Enlist cotton, corn and soybeans in Alabama, Arizona, Colorado, Delaware, Florida, Georgia, Kentucky, Maryland, Michigan, North Carolina, New Jersey, New Mexico, New York, Pennsylvania, South Carolina, Tennessee, Texas, Virginia and West Virginia.
