Syngenta announced the name of its new corn herbicide premix with four active ingredients. Currently code-named SYN-A197, the product will be marketed as Acuron herbicide upon EPA registration, which is expected for the 2015 growing season.

Syngenta developed Acuron in response to the expanding problem of weed resistance and the resulting increase in demand for residual herbicide products with multiple modes of action. The new herbicide premix combines three complementary modes of action and four active ingredients, including new bicyclopyrone, to deliver a multi-targeted approach to weed control.

“As weeds have evolved and become harder to manage, many current weed control programs have lost effectiveness,” said Gordon Vail, Ph.D., technical product lead for herbicides, Syngenta. “Research shows the addition of bicyclopyrone provides better, more consistent weed control than today’s standards.”

Syngenta anticipates Acuron will control more than 70 broadleaf weeds and annual grasses, including giant ragweed, common ragweed, marestail, kochia, Palmer amaranth, waterhemp, cocklebur and morningglory. The formulation will contain a safener, benoxacor, and its application timing is expected to be from 28 days pre-plant up to 12-inch corn.

“In university and in-house trials, we’ve seen Acuron bring a new level of control to difficult-to-control weeds, like giant ragweed, morningglory and cocklebur, that other pre-emerge residual herbicides have been missing,” said Scott Cully, research and development scientist, Syngenta. “And it continues to provide control of those weeds well into the season.”

Growers and retailers will have a chance to see Acuron in 25-30 university trials and 15-20 Syngenta field trials this summer.
