Corn Growers Achieve True One-Pass Control with Corvus Herbicide

5.6-ounce rate controlled weeds early and provided long-lasting control.

RESEARCH TRIANGLE PARK, N.C. (January 19, 2011) —“One pass. Zero doubts.” is more than a slogan for growers who used Corvus® herbicide during the 2010 growing season, as they attained effective weed control with just one pass.

“This is the herbicide’s second year on the market and it has performed exceptionally well in both seasons, despite sporadic weather conditions,” says Jeff Springsteen, Bayer CropScience marketing manager for selective corn and soybean herbicides. “Some farmers told us if they had chosen a two-pass program this year, rain would have prevented them from applying their post application. Corvus eliminated that worry because it was applied early and worked all season.”

In a 2003 article, Bob Hartzler, Iowa State University Extension weed specialist and professor of agronomy, wrote: “Is one-pass weed control an agrarian nirvana, or has technology finally given farmers the ability to consistently control weeds with a single trip across the field?”

Unsuccessful attempts over the past several years have caused many growers to affirm Hartzler’s former question, as they generally had to come back with a rescue post application. Today, however, Corvus users say they’ve made one pass a reality.

Corn and soybean producer Bryan Sharp, Taylorville, Ill., says Corvus provides an additional mode of action, but doesn’t require an extra trip across the field.

“Corvus offers a one-pass program that I’m confident in and don’t have to worry about. That means a lot to me,” Sharp says. “I like to change up modes of action. I can do something different in one pass, whereas with other alternatives, I would have to do multiple passes. It just offers a complete package.”

Just 5.6 fl oz/A of Corvus with atrazine provided consistent, long-lasting control of tough grass and broadleaf weeds, such giant ragweed, waterhemp and shattercane, across the Corn Belt.

Eric Berger says he saw Corvus action on hard-to-control giant ragweed pressure in his Wakarusa, Ind., fields: “We had just finished spraying the corn and got heavy rain for about six weeks, so I was concerned about whether Corvus would handle it. Some of our neighbors had a terrible mess with giant ragweed this year, but we didn’t have that problem.”

Corn producer Jim Williams, Cisco, Ill., says obtaining one-pass control was simple. He advises farmers who are considering the herbicide for the 2011 season to follow the recommended labeled rate.

“Farmers sometimes like to cut their herbicide rates,” says Williams, who applied Corvus to all his corn acres this year. “Go full rate. Don’t cut the rate because you will have to spend more money to go back in and rescue. If you go full rate with Corvus, you’ll be fine.”

Spraying the herbicide when weeds are less than 4 inches tall provides
optimal control, Springsteen says.

“Fighting weeds early is essential to producing a high-yielding crop. Clean fields allow corn to get off to a good start without competing with weeds for nutrients and sunlight.”

He adds: “Corvus is a true one-pass because it provides burndown, reactivation and residual through crop canopy. There’s no other product like it on the market.”

In addition to controlling a broad spectrum of weeds, Corvus is perfect for any tillage program and has no interactions with other crop protection products.
