Now is the time to control weeds in double-crop soybeans.

Herbicide formulations can dramatically influence herbicide performance, from efficacy to compatibility to shelf life.

Enlist E3 soybeans are approved for cultivation in the U.S., Canada and Brazil and have received import authorization in importing countries, including China and the Philippines. The Enlist E3 trait is the only commercially available trait that confers tolerance to a new 2,4-D choline, glyphosate and glufosinate in a three-gene molecular stack.

Andy Fordice, category leader for Enlist herbicides, talks about the recent launch of the Enlist weed control system for corn, including the new choline formulation of 2,4-D in Enlist One and Enlist Duo and the addition of Assure II as a tool against grasses and volunteer corn. Fordice also addresses how the Enlist soybean system gives no-tillers a tool to control tough weeds in-crop with 2,4-D, glyphosate and glufosinate.

Last week the Environmental Protection Agency issued approval for Enlist Duo, the glyphosate/2,4-D premix for use in the Enlist corn and soybean system, in six states: Illinois, Indiana, Iowa, Ohio, South Dakota and Wisconsin.

The EPA is registering the herbicide Enlist Duo with first-time-ever restrictions to manage the problem of resistant weeds.
