Bayer's Laudis herbicide receives registration for use in corn

Agriculture.com Staff 12/06/2007 @ 9:20am

Now, corn growers can control broadleaf weeds and tough grasses with just one product: Laudis postemergence corn herbicide.

The U.S. Environmental Protection Agency (EPA) has approved Laudis for use in all corn crops, including field corn, sweet corn, popcorn and inbreds used in seed production.

Laudis is a systemic herbicide that consistently eliminates tough broadleaf weeds such as pigweeds, tall and common waterhemp, giant and common ragweed, common lambsquarters, velvetleaf, sunflower, nightshade and cocklebur.

"We also have seen Laudis outperform other postemergence herbicides, when it comes to control of stubborn grass weeds," says Jeff Springsteen, Bayer CropScience corn herbicides marketing manager.

"In field trials last summer, we observed that other herbicides did not completely eliminate the grasses; at best, they simply suppressed many of them," Springsteen adds.

He notes that Laudis has a proven, effective defense against grasses including giant and yellow foxtail, woolly cupgrass, barnyardgrass, shattercane, large crabgrass, broadleaf signalgrass and seedling Johnsongrass. Laudis, which can work in any traditional herbicide program, can be tankmixed with Liberty herbicide for application on LibertyLink hybrids. Plus, studies show adding Laudis to every tank of glyphosate applied to Roundup Ready corn provides extended control to canopy on both broadleaves and grasses, including those with proven resistance. Laudis also enhances control in other postemergence programs, company officials say.

In addition, Laudis is an excellent solution to help corn growers break herbicide resistance problems, such as glyphosate resistance, because it introduces a unique chemistry and new mode-of-action into corn growers' fields, officials add.

Once applied, Laudis provides continued control, as it stays active in the soil during the growing season, until the crop canopy forms. However, the herbicide does not limit growers' ability to rotate to soybeans the following season. Laudis provides growers with more freedom, because it has no hybrid restrictions or interactions with any insecticides, fungicides or seed treatments.

Brent Philbrook notes that Laudis is just one of six new products Bayer CropScience anticipates introducing in the next three years.

"No other company in the industry has placed the emphasis on research and development that Bayer CropScience has underway to provide agronomic solutions for growers' weed-control needs," says Philbrook, Bayer CropScience product development manager.

Laudis can be applied in corn from crop emergence up to the V-7 growth stage. To avoid any negative impact on crop yield potential from weed competition, Philbrook recommends that growers apply the herbicide at three fluid ounces per acre, before weeds reach or exceed four inches in height.

Now, corn growers can control broadleaf weeds and tough grasses with just one product: Laudis postemergence corn herbicide.
