Laudis postemergence corn herbicide proves powerful in controlling tough weeds and grasses in Minnesota

ROCHESTER, Minn. (January 9, 2009) — Combines made a clean sweep across Minnesota corn fields this season, as growers achieved outstanding postemergence broadleaf weed and grass control, with Laudis® herbicide from Bayer CropScience.

Laudis consistently took down tough broadleaf weeds, including giant ragweeds, lambsquarters and pigweeds, as well as those commonly found to be resistant to glyphosate, ALS- and triazine-based herbicides. In addition, Laudis provided application flexibility when used in traditional herbicide programs.

“Laudis fit really well into our program,” says Ryan Bushman, a certified crop adviser from Hutchinson, Minn. “It took care of our broadleaves and grasses where we normally haven’t been able to do that with other products out there.”

The herbicide provides growers with application freedom — without reducing the efficacy of other products. Specifically, it has no interactions with insecticides, fungicides or seed treatments.

When measured against similar herbicides, Laudis provided exceptional control over broadleaf weeds, including velvetleaf, waterhemp and giant foxtail, according to a 2007 evaluation of HPPD weed management systems in field corn conducted by researchers at the University of Minnesota–Rochester.

“Tankmixing 3 fl oz/A of Laudis, MSO and 0.5 lb ai/A of atrazine will increase performance on weed competition and residual control,” says Jeff Springsteen, Bayer CropScience corn herbicides marketing manager.

With its safener technology, Laudis is designed to optimize herbicide performance while minimizing crop response, which gives growers the freedom to manage weeds in all corn crop types, including: field corn, sweet corn, popcorn and even inbreds used in seed production.

Additionally, he says, Laudis is an outstanding tankmix partner with Ignite® herbicide for application on LibertyLink® hybrids and with glyphosate in Roundup Ready® corn.

“Because Laudis is flexible enough to fit the needs of both traditional and nonselective programs, it was able to provide growers with stellar performance even though we faced major obstacles with rainfall this year,” Springsteen says.
