Corn growers have access to a new one-pass, full-season weed control tool, as the U.S. Environmental Protection Agency recently approved Corvus herbicide from Bayer CropScience.
Corvus combines the power of two active ingredients to provide excellent control over more than 50 broadleaf weeds and grasses from burndown through early postemergence.
A half-inch of rain can re-activate Corvus, even after a dry period. This unique WeatherShield feature makes Corvus less sensitive to random and sporadic spring precipitation, enabling it to control weeds up to 2 inches in early-season corn.
“In our 2008 trials, we saw Corvus was very competitive during the rainy season,” says Brent Philbrook, Bayer CropScience new products development manager. “When we measured it against other products, Corvus kept fields clean through crop canopy closure.”
Whether growers have a wet or hot-and-dry season, Corvus will take down weed competition when applied to corn through the V2 stage, says Jeff Springsteen, Bayer CropScience product manager for selective corn and soybean products.
