DuPont inks multi-year supply deal with Monsanto for dicamba

MonsantoMonsanto Co. and DuPont signed a multi-year dicamba supply agreement for the United States and Canada. Terms of the deal were not disclosed.

St. Louis-based Monsanto has invested more than $1 billion in a dicamba production facility in Luling, La., to supply the herbicide as the Xtend soybean system takes hold.

DuPont will sells its new dicamba-based herbicide as DuPont FeXapan with VaporGrip technology. VaporGrip is Monsanto’s proprietary formulation that reduces dicamba drift and volatilization.

The Xtend system is being promoted to control weeds—particularly Palmer amaranth—that have grown resistant to glyphosate and PPO herbicides.

Dicamba belongs to the Herbicide Resistance Action Committee Group O, whereas glyphosate is a Group G and PPOs are Group E’s.

DuPont’s herbicide will be paired with Monsanto’s Roundup Ready 2 Xtend cropping system, which involves soybean varieties genetically modified to withstand over-the-top applications of glyphosate and dicamba.

In 2013, DuPont signed a licensing agreement with Monsanto to incorporate its Xtend trait into its Pioneer brand seeds. This season, Pioneer offered 12 soybean varieties with the Roundup Ready 2 Xtend technology.

Dicamba itself was first registered in 1967 and controls a broad array of broadleaf weeds, including those resistant to glyphosate and PPO herbicides.
