Herbicide protects soybeans from early-season competition
Available for 2009, new LibertyLink soybeans combine top genetics with built-in tolerance to the broad-spectrum weed control of Ignite herbicide. Combined with the multi-faceted seed protection of the Trilex 6000 Soybean System, the LibertyLink soybean program provides growers a complete solution for limiting early season crop threats.
"LibertyLink soybean varieties feature elite germplasm and have no yield lag or drag," said Andy Hurst, product manager, herbicide tolerant traits and Ignite herbicide at Bayer CropScience. "To maximize yield potential, it's important for growers to implement best management practices, like early weed control and seed protection."
One way to boost profits is to control weeds before they impact soybean yields, according to Bob Hartzler, Extension weed specialist and professor of agronomy at Iowa State University (ISU).
"Fields may be weed-free at harvest yet suffer significant yield losses because weeds that emerged with the crop were allowed to grow until after the critical period was reached," explained Hartzler in a March 2007 article published in the Integrated Crop Management newsletter.
A Michigan State University study found that if growers allow weeds to grow 6 inches tall before applying a postemergence herbicide, they may experience a yield loss of up to 10 bu/A to 14 bu/A for soybeans planted in 15-inch and 7.5-inch rows, respectively.
Bayer CropScience promotes the use of pre-emergence residual herbicides, followed by a timely Ignite herbicide application, when weeds are 3 to 4 inches tall. This limits the time weeds compete with soybean plants for nutrients, water and sunlight, Hurst said.
Hurst reminds growers that another way to maximize soybean yields is to protect seeds before they hit the ground.
In 2009, all LibertyLink soybeans will feature the advanced protection of the Trilex 6000 Soybean System, which combines six powerful layers of protection, including two fungicides, a biological fungicide and an insecticide. All layers of Trilex 6000 combine to give growers increased crop vigor in their stands and yields.
"The Trilex 6000 Soybean System safeguards seed from a wide variety of early season insects and disease, protecting yield potential of top genetics, like those offered in LibertyLink varieties," Hurst said.
