Delayed Spring Planting Puts Greater Emphasis on Postemergence Weed Control

RESEARCH TRIANGLE PARK, N.C. (June 4, 2009) — With more than 92 percent of corn planted, according to the USDA, sprayer booms are replacing planters in many fields. Because weather conditions delayed planting in almost every region this year, postemergence herbicides will get even more attention when it comes to managing weed competition to maximize yields.

“Weather can cause late planting, which in turn can reduce yields, but yields depend on a formula much more complicated than simply the planting date,” said Jeff Springsteen, Bayer CropScience corn and soybean selective herbicides product manager. “If weather has delayed planting, it also may have impacted other parts of the crop production equation. For example, weather may have prevented planned applications of pre-emergence herbicides, making postemergence herbicides that much more important for growers.”

Whether growers are making postemergence herbicide applications this year as part of a total post or planned two-pass herbicide program,

Laudis® herbicide can help them effectively take down tough grass and broadleaf weeds, such as shattercane, woolly cupgrass, barnyardgrass, waterhemp, giant ragweed, kochia and wild-proso millet.

Laudis is approved for use on field corn, white corn, seed corn, sweet corn and popcorn. It has a flexible application window from VE up to V8 growth stages in field corn and popcorn, and from VE up to V7 in sweet corn. Laudis combines a powerful herbicide active ingredient with a highly effective crop safener to deliver outstanding weed control in harmony with corn — and future cropping plans.

Retailers, applicators and growers saw the performance of Laudis exceed high expectations in 2008, the first year it was available.

“I applied Laudis to one grower’s 800-acre field and we saw great results. We used Laudis as a total post program with Steadfast® and a little bit of atrazine,” said Gerrit Thompson, applicator and crop consultant with Crop Production Service in Roachdale, Ind. “We compared Laudis to Callisto® and Laudis did a phenomenal job. In the past, we’ve seen a little bit of burn with a Steadfast and Callisto tankmix. But when we used Laudis we didn’t see any burn at all.”

Springsteen added that Laudis is rainfast in just one hour, so if the wet weather conditions that hovered over many regions in 2008 extend into 2009, growers need just a short window of clear weather for application.
