Dow AgroSciences Produces 2,4-D Choline
November 9, 2011 Dow AgroSciences has successfully produced 2,4-D choline in a commercial scale-up setting. This milestone is an indicator of the company’s manufacturing expertise to produce Enlist Duo herbicide, which will be a highly differentiated herbicide solution for its Enlist Weed Control System. Once all regulatory approvals are secured, Enlist will introduce an innovative combination of herbicides and herbicide-tolerant traits in elite germplasm to meet the emerging weed control challenges facing farmers, while sustaining beneficial farming practices.
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.
Colex-D Technology is a technology package featured in Enlist Duo and is comprised of 2,4-D choline, the latest in formulation science and a propriety manufacturing process. Those components taken together will provide growers with new benefits with the herbicide, including ultra-low volatility, minimized potential for drift, decreased odor and improved handling characteristics.
“Our success in achieving commercial-scale production of 2,4-D choline is a result of our on-going investment and expertise in research, manufacturing and formulation science, ” says Joe Vertin, global leader, Enlist Weed Control System, Dow AgroSciences. “This effort was done safely, on schedule, and validates our ability to deliver on the benefits of Enlist Duo with Colex-D Technology, as we move down the regulatory pathway. Colex-D Technology is an important aspect of our overall stewardship program for the Enlist Weed Control System.”
