One-Pass Weed Control Program Economical for Farmers

Corvus users save costs by not making second trip over corn fields.

RESEARCH TRIANGLE PARK, N.C. (February 28, 2011) — Farmers across the Corn Belt continually look for ways to save money, increase yields and boost profit margins. As such, many corn growers have turned to one-pass herbicide programs to save time, labor and follow-up application costs.

Bruce Erickson, director of cropping systems management with Purdue University Department of Agricultural Economics, advises growers consider cost savings as well as weed control efficacy when choosing one-pass systems.

“Every pass across the field adds an expense, and the expense comes in terms of the operator’s time involved, the fuel to manage the equipment and the cost of the equipment. So, anytime you’re reducing a pass across the field, you’re reducing expenses,” Erickson says. “That needs to be balanced with the effectiveness of the one pass versus the additional pass across the field. If you can control [weeds] with one pass, then you’ve cut your application expenses in half.”

Kansas corn and soybean producer Kevin Lingenfelter says he likes the cost savings that one-pass programs bring to his operation: “I like doing one pass as much as I can just for the economics of it. Anytime I can save a little money, that’s the route I want to take.”

Corn and soybean producer Spencer West agrees with Lingenfelter, as he says one-pass programs, like Corvus® pre-emergence corn herbicide from Bayer CropScience, are more economical than what some growers might think.

“A two-pass program is not any cheaper than a one-pass program,” says the LeRoy, Kan. farmer. “With the one-pass program, you save an application trip, so you might as well get it in one pass. Everybody thinks that one pass is higher, but when you figure out the price of a second pass, it’s not.”

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.

“Farmers know the one-pass weed control of Corvus is consistent, as they’ve seen its efficacy, whether the season is hot and dry or cool and wet,” says Jeff Springsteen, Bayer CropScience marketing manager for selective corn and soybean herbicides. “Since its introduction, more and more growers have found that the unique herbicide creates a one-pass zone that helps them to save time, labor and costs that they weren’t able to save with previous herbicide programs.”
