DuPont will be selling its new DuPont FeXapan herbicide plus VaporGrip Technology, which is a version of Monsanto's dicamba and Roundup herbicides for use with Roundup Ready Xtend Crop System crops. Monsanto Company and DuPont signed a multi-year dicamba supply agreement for the U.S. and Canada to make this possible.

Monsanto is placing huge expectations on the desire by farmers to plant soybeans that can be grown with its dicamba, Roundup formulation sprayed postemerge.

“This agreement represents continued commitment to the Roundup Ready Xtend Crop System,” said Mike Frank, Monsanto vice president, chief commercial officer. “Low-volatility dicamba formulations with VaporGrip Technology are designed to give soybean farmers additional tools to control glyphosate-resistant and tough-to-control broadleaf weeds.”

“For several years, DuPont has been testing a solutions-based approach to optimizing weed control using this novel soybean trait and dicamba formulation technology,” said Tim Glenn, president, DuPont Crop Protection. “We are seeing excellent results in improved control of weed populations, including those resistant to a number of herbicide modes of action. This advance will help farmers manage weed competition while improving crop safety as they work to increase production to meet global food demand.”

The companies noted that dicamba has been a popular broadleaf herbicide since being introduced in 1967. It is widely used around the world, and the Monsanto formulation isthe latest formulation. Various dicambe formulations have been developed through the years. The main concern about dicamba as been potential volatilization. Dicamba's uses have included corn, wheat, fallow, pasture land, conservation tillage and lawn care.

In announcing the new DuPont herbicide option and promoting the Monsanto Roundup Ready Xtend Crop System, the two companies noted their involvement in the Take Action agricultural industry partnership between university weed scientists, major herbicide providers and organizations representing corn, cotton, sorghum, soybean and wheat for helping farmers manage herbicide-resistant weeds. The Take Action effort encourages farmers to develop a proactive strategy to manage herbicide-resistant weeds that incorporates a diverse set of controls.
