Growing a business by farming more acres can mean more money in the bank. But, it also means enterprising farmers must carefully choose the best weed management program for their operations.

After all, managing more acres in a limited amount of time calls for an efficient, simple and effective program. As corn producers consider ways to increase profitability through higher crop yields and expanded profit margins, many turn to one-pass herbicide programs to control weeds early, and all season long.

“Farmers need two or more effective modes of action that have activity on their target weed species,” says Bryan Young, weed specialist at Southern Illinois University. “If they can do a one- pass at planting and [the fields are] weed-free for the rest of the season, that would be their greatest return on investment.”

Today, return on investment encompasses more than the bottom line. Farmers are weighing how much time, handling and effort it takes to apply their inputs. And given that many are trying to cover the most acres in the least amount of time, one-pass has become increasingly important.

Bryan Henrichs, St. Rose, Ill., dairy and grain producer, says dependable one-pass control is one of the first things he looks for in a corn weed management program. In addition to producing corn crops, he raises soybeans, wheat, alfalfa, canola and 200 head of dairy cows, so time is limited and he doesn’t want to “babysit [his] corn.”

“With the dairy and all the custom work, we usually don’t have time to be scouting our fields constantly,” Henrichs says. “With Corvus, we know that if we put that down we usually don’t have to go back and watch for weeds popping out again.”

A single-trip program, such as Corvus® pre-emergence corn herbicide from Bayer CropScience, offers farmers like Henrichs savings in time, labor and follow-up application costs.

“The most expensive weed control program is the one that doesn’t work,” Henrichs says. “Before we switched to our current weed control program, we looked at prices of the program and it was a little more expensive than what I was hoping. But, we’ve never had to come back and respray… because it’s pretty much taken care of all the weeds.”

Corvus controls more than 50 hard-to-kill grass and broadleaf weeds with just one pass. A tankmix of 5.6 fl oz/A of Corvus with atrazine offers rapid burndown, reactivation and residual control of weeds — such as Palmer amaranth, ragweed and waterhemp — that have become resistant to glyphosate-, ALS-, PPO- and triazine-based chemistries.

Resistant weeds cost farmers the utility of an entire class of herbicide chemistry in addition to time and money, according to Bruce Erickson, agronomic education manager for the American Society of Agronomy and adjunct assistant professor for the Purdue University Department of Agronomy.

“If you get these resistant weeds on your farm, then you’ve eliminated a whole group of pesticides that you may never use again on that farm,” Erickson says. “There is potentially a big economic cost to that by eliminating a whole suite of options. That to me is a big economic driver on resistance management.”

Corvus is flexible enough to be applied from pre-plant through the V2 growth stage in corn. It also can be applied on various soil types — including sandy loam and heavy clay — without injuring the crop, thanks to Bayer’s highly active Crop Safety Innovation (CSI™) Safener technology.

“Corvus helps farmers farm more efficiently by controlling weeds in one pass,” says Jeff Springsteen, herbicides manager for Bayer CropScience. “It has a wide window of application in the event weather keeps them out of the field. Plus, its reactivation properties continue to control weeds throughout the season with just a half-inch of rainfall. All in all, it’s a great option for farmers.”
