US EPA registration expands uses for AMVAC's Impact herbicide

AMVAC^®, a subsidiary of American Vanguard^®, announces US Environmental Protection Agency (EPA) label changes that expand the use of Impact^® Herbicide – The Standard in Corn Safety^®.

Impact Herbicide has received federal EPA approval to apply up to 2 fluid ounces per acre in either single or sequential applications in corn. This expanded use adds control of Texas panicum, field sandbur, and shattercane in tank mixes with atrazine, and increases the maximum size for control of yellow foxtail, fall panicum, woolly cupgrass, and broadleaf signalgrass.

Additionally, this registration will allow use of Impact following application of Impact CORE^® Herbicide and Sinate^® Herbicide – both new for the 2021 growing season – as well as ImpactZ^®.

“Impact Herbicide has been a mainstay of weed control programs for some time,” said Nathaniel Quinn, AMVAC Marketing Manager for Corn, Soybeans, and Sugar Beets. “We’re pleased to be able to extend Impact’s effectiveness to even more weeds and application situations.”
