Registration for Fierce herbicide, a new residual for corn and soybeans, is pending, and Valent expects the product to be available for the 2011 growing season. Fierce contains flumioxazin (the active ingredient found in the Valor herbicide) and pyroxasulfone. The herbicide can be applied in the spring up to seven days before planting corn and up to three days after planting soybeans. It can also be applied in the fall. Fierce provides 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.
