Enlist Duo™

  • Herbicide


  • 4
  • 9

Enlist Duo™ combines two proven modes of action for exceptional control of a broad spectrum of weeds, including hard-to-control and resistant weeds. So much for those so-called “tough” weeds.


Used as part of the Enlist™ weed control system in Enlist corn, Enlist E3™ soybeans or as a burndown in cereal crops, discover why Enlist Duo is an effective tool for broad-spectrum weed control.

Convenient formulation

Soybean pod close-up Enlist Duo with Colex-D™ technology is a new co-formulation of glyphosate and 2,4-D choline that offers convenience, easy handling and low volatility.

Exceptional flexibility

Soybean pod close-up

The two modes of action in Enlist Duo provide exceptional and consistent weed control in a variety of weather conditions and application timings. Use it for broad-spectrum weed control in Enlist corn, Enlist E3 soybeans or as a burndown for winter annuals and broadleaf weeds ahead of field corn, winter wheat, spring wheat and barley.

Superior weed control

Corn from the ground up

Enlist Duo controls over 70 grass and broadleaf weeds. The combination of Group 9 and Group 4 active ingredients in Enlist Duo enables control of weeds that glyphosate alone may miss.
