Corn growers can count on one-pass, full-season grass and broadleaf weed control with Corvus herbicide

5.6-ounce rate locks out weed competition early and reactivates for long-lasting control

RESEARCH TRIANGLE PARK, N.C. (March 29, 2010) — With one application of Corvus® herbicide this spring, corn growers can count on superior weed control that starts early and keeps on working all season long.

The 5.6 fl oz/A application rate is key to gaining season-long control with the one-pass strategy, says Jeff Springsteen, Bayer CropScience marketing manager for selective corn and soybean herbicides. He notes that corn growers in the Midwest achieved dependable control with that application rate repeatedly in 2009, the product’s first year of use.

“Last year was challenging for many herbicides, and what we saw repeatedly was that Corvus stepped up and got the job done in a single pass, even under adverse weather conditions,” he says. Springsteen adds: “Corvus is unique because you get burndown, residual and reactivation control of grass and broadleaf weeds all in a single pre-emergence product; there’s nothing else like it in the marketplace.”

Part of what makes the herbicide unique and so reliable is its Crop Safety Innovation (CSI™) Safener technology, which enhances the natural ability of corn plants to tolerate herbicide activity.

Ohio corn grower, John Dovin, says he values the outstanding weed control, safety and application flexibility that Corvus offers.

“We’ve used other one-pass programs in the past, but I wasn’t nearly as satisfied with the crop safety as I am with Corvus,” says Dovin of Oberlin, Ohio. “Corvus is a real step up from its competitors. Its safener technology works extremely well. It offers complete weed control throughout the season and the flexibility to be applied early post, which is a nice benefit because weather is so sporadic in this part of Ohio.”

Dovin adds: “It brought to my fields superior weed control power, nice cost savings of a one-pass program and excellent crop safety. You couldn’t ask for anything more in a herbicide.”

Corvus offers two modes of action to control weeds: one inhibits the production of HPPD enzymes in plants, and the other prevents certain amino acids from blocking plant growth and development.

That combination enables Corvus to effectively control more than 50 different weeds, many of which are resistant to glyphosate, ALS or triazine herbicides, including Palmer amaranth, waterhemp and marestail, plus tough grasses like woolly cupgrass, yellow foxtail and fall panicum.

“We have a major problem with horseweed, and typically a one-pass product doesn’t work, but Corvus seemed to take down horseweed with no problem,” says Steve Magner, a grower and salesman with Crop Production Services in Willbanon, Ind.

In addition to controlling a diverse spectrum of grass and broadleaf weeds, Corvus is perfect for any tillage program, including no-till and minimum till.
