Are you planting Enlist E3 soybeans in 2022?  If so, one of the tools in the weed control toolbox will be the option to use one of the two registered 2,4-D choline herbicides for use on Enlist E3 soybeans.  In January 2022, the EPA approved a seven-year registration of Enlist One and Enlist Duo herbicides.  Enlist One and Enlist Duo are the only 2,4-D choline herbicides registered for over-the-top use in 2,4-D tolerant soybeans.  Enlist E3 soybeans are also tolerant to the over-the-top application of both glyphosate (Roundup) and glufosinate (Liberty) herbicides.
