Dow AgroSciences, DuPont reach soybean herbicide trait deal

Agriculture.com Staff 11/12/2009 @ 8:36am

Dow AgroSciences and DuPont have entered into a commercial cross-licensing agreement regarding soybean herbicide-tolerant traits.

Under the agreement, Dow AgroSciences is licensing non-exclusively its proprietary herbicide tolerant trait technology for soybeans to DuPont business Pioneer Hi-Bred. In addition, Pioneer is licensing non-exclusively its proprietary Optimum GAT trait for soybeans to Dow AgroSciences. Both companies have given the other rights to stack additional traits with their respective technology. Financial details of the agreement were not disclosed.

Officials for both companies in a press release said the new herbicide tolerant trait technology allows growers to continue farming the way they want, but with improved weed control capabilities and performance. The system is designed to provide excellent control of glyphosate-resistant and other hard-to-control broadleaf weeds including:

  • morning glory
  • pigweeds including palmer amaranth
  • lambsquarters
  • marestail
  • waterhemp
  • giant and common ragweed
  • velvetleaf

In anticipation of regulatory approvals for its herbicide tolerant trait technology, Dow AgroSciences is developing new and improved herbicide solutions based on 2,4-dichlorophenoxy acetic acid technology growers have used successfully for more than 60 years, say Dow officials.

When stacked together, the Optimum GAT trait from Pioneer and the new herbicide tolerant trait technology being developed by Dow AgroSciences would produce soybeans that are tolerant to 2,4-D, glyphosate and ALS herbicides, say company officials. The Optimum GAT trait from Pioneer provides tolerance to glyphosate and the ALS class of herbicides. Optimum GAT soybeans have received U.S. regulatory approvals and a 2011 introduction is anticipated upon regulatory approvals in key importing countries.

DuPont also anticipates the introduction of five new ALS-based herbicide products for Optimum GAT soybeans, including DuPont Freestyle, Trigate, Traverse, Instigate, and Diligent herbicides, upon U.S. and state approvals.
