Laudis herbicide proves safe for specialty corn hybrids

Its powerful postemergence weed control chemistry and gentle safener work together to protect sensitive corn from yield-robbing competition.

RESEARCH TRIANGLE PARK, N.C. (April 5, 2010) — Crop injury due to herbicide treatment is one of the more difficult aspects of raising specialty corn hybrids, like seed corn, according to one Michigan retailer.

“There aren’t many products that seed corn companies allow to be used on certain corn,” says Jon Silsby, owner of TH Agri-Chemicals Inc. in Union City, Mich. “So, some of our challenge is the type of products we’re actually allowed to use. Plus, we have weed control challenges.”

Silsby says Laudis® postemergence corn herbicide from Bayer CropScience works “extremely well” against those challenges because seed companies like its crop safety feature and growers like its broad-spectrum weed control.

Laudis has proven to be tough on weeds, yet gentle on all corn hybrids since its 2008 introductory year, says Jeff Springsteen, Bayer CropScience marketing manager for selective corn and soybean herbicides.

“The residual weed control power and crop safety feature in Laudis offer growers a combination not often seen in selective herbicides,” Springsteen says. “Crop tolerance to Laudis surpasses that of other herbicides within the same chemical family, as well as those in traditional herbicide classes, like SU chemistries. Plus, its proprietary safener makes it safe enough to be used on specialty corn types with no risk of crop injury.”

Henry Farms LLC in Dane, Wis., experimented with Laudis on a small scale in 2008, and then applied it at the V4 growth stage on all their seed corn acres in 2009.

“Our seed corn did not experience crop injury at all,” says Dale Gretebeck, production manager for Henry Farms LLC. “We began seeing weeds die within five to seven days. We don’t usually apply atrazine to our seed corn, but we experimented with a Laudis plus atrazine tankmix on one field and saw weeds start to brown in the first few days.”

Laudis is safe to use on all corn types, including field corn, seed corn, sweet corn, white corn, popcorn and corn grown for silage, and controls more than 65 grass and broadleaf weeds, including those resistant to glyphosate-, ALS-, PPO- and dicamba-based chemistries. The herbicide also has a flexible application window, as it can be applied from VE up to V8 growth stages in field corn and popcorn, or up to the V7 growth stage in sweet corn.

“Our scout encouraged us to use Laudis back in 2008. His consultation and my research say Laudis provides safety in seed corn,” Gretebeck says. “We are a conservative operation, and I can say that we’ve finally found a herbicide that works even beyond our expectations.”
