Registration of Enlist One and Enlist Duo Herbicides

The US-EPA has renewed the registrations for Enlist One and Enlist Duo herbicides that can be applied to genetically modified (Enlist) corn, soybean, and cotton. The time-limited (7 years) registrations for both herbicides contain additional measures to protect plants and animals. Click here for the EPA document that provides details about this action.

Both Enlist One (active ingredient 2,4-D, choline salt–Group 4 herbicide) and Enlist Duo (active ingredients 2,4-D, choline salt and glyphosate–Groups 4 and 9 herbicides) are registered to control weeds when applied postemergence (PE) to Enlist corn, soybean, and cotton crops. They are also registered for preplant burndown of annual and perennial weeds in fields to be planted to either conventional or Enlist varieties/hybrids so that crops can be planted in a weed-free environment without tillage. Click here to access up-to-date labels that provide specific guidelines for both preplant and PE applications of each product.
