Valent anticipates that Fierce, a pre-emergence herbicide (pyroxasulfone and flumioxazin) for use in reduced-tillage field corn and soybeans, will receive registration for corn in time for the 2012 season. Fierce has shown residual control of weeds including glyphosate-, ALS- and triazine-resistant Palmer amaranth, waterhemp, common lambsquarters, velvetleaf, dandelion, marestail, annual nightshades, pigweed species and annual grasses, the company says.
John Jacobs has always used glyphosate to clean up weed problems on his farm, especially problem fields. But for the most part, he’s never really strayed from a conventional weed-control program for his soybeans. “My basic plan is to plant beans, and use Prowl and Valor in the spring,” he says. “My weed-control program is about $20/acre, but I’m not paying a tech fee.”
