The U.S. Environmental Protection Agency has approved Enlist Duo herbicide for use in four Mid-South states — Arkansas, Louisiana, Missouri and Mississippi.
Enlist Duo with Colex-D technology combines glyphosate with 2,4-D choline for weed control in corn and soybeans. It is part of Dow AgroSciences’ Enlist Weed Control System.
Other approved states include Kansas, Minnesota, 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 is working 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 registration documents for Enlist Duo issued Oct. 15, 2014, 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 also stated, “when used according to label directions, Enlist Duo is safe for everyone.”
Growers from on-farm trials rated weed control with Enlist Duo herbicide higher than their current weed control system and said it provided improved weed control — particularly of glyphosate-resistant weeds.
Growers were also impressed with the technology’s lack of drift and volatility, according to Dow AgroSciences.
“The proprietary Colex-D Technology in Enlist Duo helps ensure the herbicide lands and stays on target with minimized potential for drift and volatility,” a news release said.
“Reduced off-target movement is important on our farm,” said Kansas producer Josh Lloyd. “I want a product that will stay exactly where we spray it. It’s a tool that will help many Kansas growers manage tough weeds.”
Dow AgroSciences will launch Enlist Duo in conjunction with a stewarded introduction of Enlist corn and seed production of Enlist soybeans in 2015. With today’s announcement, growers in key production areas soon will have access to the new herbicide technology. The company continues to work with the EPA to further expand the list of states on the federal label.
