Dicamba Facts image

On Oct. 13, 2017, the U.S. Environmental Protection Agency (EPA) announced an agreement with Monsanto, BASF and DuPont on measures to minimize the potential for off-target movement of Dicamba and further ensure effective use of three pesticides: DuPont’s FeXapan, BASF’s Engenia and Monsanto’s XtendiMax.

In a collaborative effort to safeguard Missouri agriculture, the Missouri Department of Agriculture issued a 24c Special Local Need label for ENGENIA Herbicide on Nov. 16, 2017, EPA Registration Number 7969-345 – SLN label MO-180001. The Department subsequently issued 24c Special Local Need labels for XTENDIMAX, EPA Registration Number 524-617, and FEXAPAN, EPA Registration Number 352-913, on Dec. 11, 2017. All three labels contain the same restrictions.
