The Environmental Protection Agency this week issued the announcement that registration of Enlist Duo herbicide was open to public comment, but at the same time, Dow AgroSciences, the developer of Enlist Duo, issued its version of the EPA stage of registration. The company news was that “the U.S. Environmental Protection Agency (EPA) announced its proposed decision to register Enlist Duo.

The 30-day comment period is a step forward, which would indicate the registration is proceeding and the EPA is inclined to register the herbicide.

A Dow AgroSciences news release points out how great Enlist Duo would be in improving weed control, especially herbicide-resistant weeds, and how the Colex-D Technology 2,4-D choline herbicide component “will provide stewardship and user benefits, including minimized potential for physical drift, ultra-low volatility, reduced odor and better handling characteristics.”

Enlist Duo is a proprietary blend of the new 2,4-D choline and glyphosate herbicides.

Damon Palmer, U.S. commercial leader for the Enlist Weed Control System, said, “In its review, the EPA acknowledged the significant scientific advancements Dow AgroSciences made with Enlist Duo herbicide as it relates to off-target movement.”

The draft label for Enlist Duo includes proposed registration for Iowa, Illinois, Indiana, Ohio, South Dakota and Wisconsin. The company is working with the EPA to expand the list of states in time for the technology’s launch, it was noted.

Dow AgroSciences is confident that the U.S. Department of Agriculture will give regulatory approval for corn and soybeans engineered to tolerate Enlist Duo postemerge in the near future. All indications are that the two Enlist crops will be approved for commercialization in 2015, which means farmers could have seed to plant in the spring of 2015.

Dow AgroSciences is asking for support of Enlist Duo during the registration comment period by signing the petition at or leaving a comment on the EPA docket.

The company provided a succinct explanation of why Enlist Duo deserves support based on 2013 on-farm research activity. “The research plot participants rated Enlist Duo in the highest percentile (90 to 100 percent) for broadleaf and grass weed control across all plots. These growers were also asked to evaluate the drift and volatility potential of Enlist Duo herbicide with Colex-D Technology. Lab and in-field research has shown that using Enlist Duo with Colex-D Technology in combination with a low-drift spray nozzle can decrease physical drift by up to 90 percent when compared with a tank mix of glyphosate and traditional 2,4-D sprayed through a standard XR nozzle. The new Enlist Duo also will have up to 96 percent reduction in volatility compared with traditional 2,4-D products.”
