EPA Registers First Dow AgroSciences 2,4-D Choline Product Submission

Indianapolis — Dow AgroSciences LLC, a subsidiary of The Dow Chemical Company (NYSE: DOW), announced today that the U.S. Environmental Protection Agency (EPA) has accepted the company’s submission for a new 2,4-D choline product. Colex-DTechnology will be featured in the 2,4-D choline herbicide solution for Dow AgroSciences’ EnlistWeed Control System. Various components of the system are currently pending U.S. regulatory approvals.

The herbicide solution for Enlist is centered on the innovative choline salt of 2,4-D. The new 2,4-D choline is a quaternary ammonium salt, which is different from 2,4-D amine or ester formulations. This technology retains the positive attributes of traditional 2,4-D products, such as the same weed control efficacy and favorable environmental profile, while providing growers new advantages for the management of resistant and hard-to-control weeds.

“This is an important approval for the Enlist Weed Control System as we continue to lead the way in bringing forward answers for farmers’ weed control issues,” said Daniel Kittle, Ph.D., Vice President of Research and Development at Dow AgroSciences. “We are committed to addressing some of the planet’s most significant challenges by delivering game-changing technology to advance agriculture.”

The Enlist Weed Control System will help growers manage the trend of increasing prevalence of difficult-to-control weeds, including glyphosate-resistant species. Enlist will be the first new tool to build on and improve the glyphosate-tolerant cropping system and provide control of problematic weeds like waterhemp, an aggressive yield-robbing weed found in many corn-and soybean-growing areas. Waterhemp has been documented as glyphosate-resistant and was recently documented as resistant to the HPPD mode of action.

In addition to exceptional weed control provided by the new 2,4-D choline, Colex-D Technology will provide a suite of beneficial attributes. These will include reduced volatility, minimized potential for drift, decreased odor, plus improved handling and tank-mixing characteristics.

Dow AgroSciences is developing the EnlistWeed Control System to offer exceptional weed control by partnering with and improving existing glyphosate-tolerant cropping systems, which are known for flexibility, convenience and value. Enlist will incorporate a combination of herbicides, traits in elite genetics and stewardship programs that will help farmers continue to advance modern farming.
