Syngenta seeks approval for dicamba-tolerant herbicide

Published:

Syngenta is seeking EPA approval for their new herbicide featuring the active ingredients of S-metolachlor and dicamba for preplant, at-planting, and post-emergence use on Roundup Ready 2 Xtend Soybeans and Bollgard II XtendFlex Cotton, and preplant application on non-dicamba-tolerant soybeans. Tavium plus VaporGrip Technology (Tay-vee-um) will offer growers another tool to manage key ALS-, PPO- and glyphosate-resistant broadleaf and grass weeds with its built-in resistance management.

“Tavium will provide growers a new herbicide designed specifically for dicamba-tolerant soybeans and cotton,” said John Appel, herbicide product lead at Syngenta. “The addition of S-metolachlor to dicamba in a premix will not only help manage resistance, but will provide residual control compared to solo dicamba products.”

The S-metolachlor/dicamba premix will target driver weeds, including Palmer amaranth, waterhemp, common and giant ragweed, kochia, horseweed (marestail), morningglory, barnyardgrass, and foxtail. In addition to its two active ingredients, the herbicide contains VaporGrip Technology to decrease dicamba volatility. Once available, growers will be able to apply the herbicide preplant, at planting, pre-emergence, and post-emergence on dicamba-tolerant cotton and soybeans, and as a preplant herbicide on non-dicamba-tolerant soybeans.

“Compared to other stand-alone dicamba products, this herbicide’s dual modes of action broaden the activity spectrum and increase its overall efficacy and sustainability,” said Don Porter, technical herbicide product lead at Syngenta. “To stand a fighting chance against aggressive weeds, we need a herbicide with multiple effective modes of action that controls emerged weeds through contact activity and weeds that have yet to emerge through residual activity.”

Tavium premix will be commercially available for future growing seasons upon EPA approval and receipt of individual state registrations.
