Corn herbicide offers options despite weather conditions


RESEARCH TRIANGLE PARK, N.C. — Farmers across the Corn Belt plant diverse corn hybrids in multiple soil types at various times, but the one thing that remains consistent on nearly every farm is unpredictable weather.

Over the last few years, unusually wet weather delayed timely herbicide applications, leading many custom applicators to suggest one-pass programs to their customers.

“With products like Capreno coming out on the market, I think we will see a switch into one pass with the weather we have had the past three years,” says Beau Morris, a Stewardson, Ill. retailer and corn and soybean producer. “People get tired of driving through four-foot-tall corn and making tracks with sprayers just to apply Roundup®.”

Though the last several years have been exceptionally wet in many regions, farmers know they can’t predict if the wet weather will continue, or if 2011 will deliver average or below normal rainfall. With Capreno® postemergence corn herbicide from Bayer CropScience, growers get the advantage of end-of-season clean despite weather conditions.

The herbicide’s flexible application timing was handy for Taylorville, Ill., corn and soybean producer Bryan Sharp, when he couldn’t get into the field to apply a pre-emergence herbicide to all his corn acres.

“If I’m not as timely at getting the herbicide applications made in my window of opportunity, we generally have a fall back,” Sharp says. “Corn was over four collars and we had to jump to a different product. Capreno was that this year. It opened up another window for me to get something accomplished.”

Capreno offers the longest-lasting residual of any post and can be applied from V1 up to the V5 corn growth stage to control more than 65 grass and broadleaf weeds. At just 3 fl oz/A, the postemergence corn herbicide is strong enough to control glyphosate-, ALS-, PPO-, dicamba and triazine-resistant weeds in one pass.

Jeff Springsteen, Bayer CropScience marketing manager for selective corn and soybean herbicides, reminds growers that Capreno is an effective option in all weather conditions.

“Many growers have switched to total post programs to ensure weed control because weather is so unreliable,” Springsteen says. “Whether growers experience a dry, normal or wet season, Capreno is a herbicide they won’t have to worry about because it provides the efficacy they need through crop canopy.”

For clean fields at the end of the season, Springsteen recommends growers apply Capreno early with atrazine and/or glyphosate or Ignite® herbicide, Crop Oil Concentrate (COC) and a nitrogen source, such as UAN or AMS, when weeds are less than 4 inches tall. There is no need for additional COC if the glyphosate already includes a surfactant. Capreno offers the flexibility of application on LibertyLink®, Roundup Ready® or conventional corn acres.
