Farmers: One-pass weed control program economical

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 to 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.”

Breese, Ill., grain and livestock producer Bryan Henrichs says Corvus® one-pass pre-emergence corn herbicide from Bayer CropScience has brought multiple savings to his operation.

“You only have one application cost and you’re not coming back in and running through the crops with a sprayer,” Henrichs says. “It saves you a lot of time. It might cost a little more money up front, but we don’t have to spray a second time. I don’t think we have ever had to come back and respray a Corvus field for weeds.”

Gary Timpner, Pinckneyville, Ill., corn and soybean producer, says overall profit potential was most important when he switched from a two-pass program to Corvus last year: “It comes down to the bottom line at the end of the year. If you don’t have to run over acres twice, it makes quite a difference.”

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.”
