The Environmental Protection Agency (EPA) announcement April 1 a 30-day public-comment period for in-crop use of dicamba herbicide with Bollgard II XtendFlex cotton and Roundup Ready 2 Xtend soybeans.

Dicamba is in the chlorophenoxy family of chemicals and is similar to 2,4-D. Target weeds include glyphosate-resistant broadleaf weeds such as Palmer amaranth, waterhemp and marestail, along with other tough-to-control broadleaf weeds such as lambsquarters and velvetleaf.

Final approval of the new technology will allow farmers to use dicamba in-crop with soybeans tolerant to dicamba and glyphosate and with cotton tolerant to dicamba, glyphosate and glufosinate.

Comments on the EPA’s proposed regulatory decision on in-crop use of dicamba must be submitted no later than April 30.
