U.S. EPA Clears Enlist Duo for Use in Additional States

The U.S. Environmental Protection Agency (EPA) announced its approval of Dow AgroSciences’ Enlist Duo herbicide for use in additional states. A key component of the innovative Enlist Weed Control System, Enlist Duo with Colex-D Technology combines glyphosate with new 2,4-D choline to control weeds in corn and soybeans.

The label for Enlist Duo now includes federal registration in many of the key corn- and soybean-producing states. The newest additions are Arkansas, Kansas, Louisiana, Minnesota, Missouri, Mississippi, Nebraska, Oklahoma and North Dakota. The originally approved states — Illinois, Indiana, Iowa, Ohio, South Dakota and Wisconsin — were included on the federal label when the EPA registered Enlist Duo for use with Enlist corn and soybeans in October 2014. Dow AgroSciences will continue to work closely with state regulatory authorities to obtain local approvals. Regulatory approvals are pending for Enlist cotton.


“More than 84 million acres of farmland are infested with glyphosate-resistant weeds. And that number continues to climb each year, making the EPA’s decision critical,” says Susanne Wasson, U.S. crop protection commercial leader, Dow AgroSciences. “Growers need access to this much-needed, effective weed control solution.”

In its registration documents for Enlist Duo issued Oct. 15, 2014, the EPA stated “2,4-D and glyphosate are two of the most widely used herbicides to control weeds in the world. Dozens of countries — including the United States, Canada, Mexico, Japan and 26 European Union Members — have approved glyphosate and 2,4-D for use on residential lawns and numerous crops.” The EPA further stated, “when used according to label directions, Enlist Duo is safe for everyone..

“Recent feedback from growers from on-farm trials overwhelmingly rated the weed control with Enlist Duo herbicide higher than their current weed control system,” Dow said in a statement. “Growers stated Enlist Duo provided improved weed control — particularly of glyphosate-resistant weeds. In addition, growers were impressed by the lack of drift and volatility. The proprietary Colex-D Technology in Enlist Duo helps ensure the herbicide lands and stays on target with minimized potential for drift and volatility.”

Dow AgroSciences says it will launch Enlist Duo in conjunction with a stewarded introduction of Enlist corn and seed production of Enlist soybeans in 2015. The company continues to work with the EPA to further expand the list of states on the federal label.
