The Environmental Protection Agency approved Fierce herbicide from Valent U.S.A. Corporation for use in no-till and reduced-till field corn. Fierce herbicide is the company’s newest residual for a long-lasting preemerge solution to tough weeds.

Fierce is a combination of Valor herbicide and a new active ingredient, pyroxasulfone. Trial results have showed this combination provides dependable, long-lasting control of the broadest spectrum of weeds and grasses.

“Growers know and believe in the excellent control Valor brings to their weed programs,” said Trey Soud, Valent product marketing manager. “By combining Valor with pyroxasulfone, growers will now have a single herbicide to tackle even the toughest weeds and grasses.”

In a series of university and private trials over 2010 and 2011, Fierce provided as much as eight weeks of residual control. Fierce also demonstrated excellent crop safety and strong control of both grass and broadleaf weeds.

“Fierce was developed for growers who desire a premium preemerge herbicide in a two-pass Roundup Ready corn system,” said Soud. “Fierce offers a complete weed control solution with outstanding residual control of a broad spectrum of tough weeds and grasses to help manage resistance and protect the farmer’s yield.”
