Dow AgroSciences tests Enlist Duo herbicide on Southern crops

Farmers throughout the South are reporting positive results with Enlist Duo herbicide with Colex-D Technology. 

As part of a study conducted by Dow AgroSciences, some growers planted PhytoGen cottonseed with the Enlist trait in on-farm research plots and applied Enlist Duo herbicide in-crop. Others put Enlist soybeans to the test on their farms. 

The farmers who used the product in on-farm research plots are now reporting reductions in off-target movement potential.

When used with recommended nozzles, Enlist Duo herbicide, featuring Colex-D Technology, provides up to 90 percent reduction in physical drift compared to traditional 2,4-D, according to Dow AgroSciences.

"It takes away the fear," Jon Whatley, Texas grower and cotton research plot participant, said. "It stayed where we applied it. I'm comfortable with it, and want the guy farming next to me to be comfortable with it and know he's not going to see damage."

Dow AgroSciences said Enlist Duo will be the only 2,4-D-containing herbicide labeled for in-crop use with Enlist soybeans and, pending regulatory approval, with Enlist cotton.

Southern farmers have been contending with a wide spectrum of resistant weeds. Growers in the study applied Enlist Duo on Palmer amaranth, marestail, giant ragweed and others with positive results.

"I never thought I would see the day that you'd be able to spray 2,4-D over cotton," Trey Koger, a Mississippi grower, said. "The crop tolerance was excellent and comparable with other herbicide programs we've used."

The Enlist Weed Control System, a herbicide-tolerant trait technology, provides growers more weed control options, according to Dow AgroSciences. Enlist cotton and Enlist soybeans provide tolerance to Enlist Duo herbicide - a proprietary blend of 2,4-D and glyphosate - as well as full tolerance to glufosinate herbicides.

The research plots in the South add to the many on-farm acres featuring the Enlist Weed Control System this season. Additional growers are participating in the stewarded introduction of Enlist corn, and the Field Forward program for Enlist soybean production in the Midwest and South.
