Valent U.S.A. LLC has received U.S. EPA approval to launch Fierce MTZ Herbicide – a stand-alone liquid formulation that combines the company's leading herbicide, Fierce Herbicide, with the added benefit of metribuzin. 

Fierceâ„¢ Herbicide (active ingredients: flumioxazin + pyroxasulfone), the newest residual from Valent U.S.A. Corporation, has received US EPA registration in soybeans. Fierce, which received registration for corn earlier this year, is now available to soybean growers for the longest-lasting, broadest spectrum control of broadleaves and grasses, including species that are resistant to glyphosate and other chemistries.
