GlyTol LibertyLink Stack Revolutionizes Mid-South, Southeast Cotton

GlyTol and GlyTol LibertyLink technologies demonstrate success in Southwest during first season

For the first time, cotton farmers can use a variety stacked with GlyTol and LibertyLink to choose the best in-season herbicide application for their farm, and they can rotate nonselective chemistries to fight weed resistance.

Farmers across the eastern Cotton Belt now have the opportunity to benefit from using a herbicide trait package from Bayer CropScience that is unlike anything else available on the market today. In a first for the Mid-South and Southeast, cotton farmers have a multiple herbicide trait package that allows them to make full-label rate applications of either Ignite® herbicide* or glyphosate to control a broad spectrum of weeds in their cotton.

For the 2012 season, Bayer CropScience announces the release of its newest FiberMax® variety, FM 1944GLB2, which contains both the GlyTol® and LibertyLink® traits. GlyTol is a glyphosate-tolerant trait that allows over-the-top, season-long use of any brand of glyphosate labeled for cotton. LibertyLink gives farmers the ability to spray Ignite herbicide over the top of cotton all season long to fight broadleaf weeds and grasses. Farmers fighting resistant and hard-to-kill weeds have a new competitive edge in their management programs.

“Cotton farmers need every advantage they can get when it comes to controlling these noxious weeds,” said Paul Callaghan, global cotton traits manager for Bayer CropScience. “For the first time, cotton farmers can use a variety stacked with GlyTol and LibertyLink to choose the best in-season herbicide application for their farm, and they can rotate nonselective chemistries to fight weed resistance. They will have confidence to use full-labeled rates to fight the toughest weeds and keep fields clean.”

FM 1944GLB2 is a proven performer across the Cotton Belt, from the Carolinas to Texas. The variety has an especially good agronomic fit in the Mid-South and Southeast, where glyphosate- resistant pigweed has caused the most problems for farmers. The variety is also an excellent fit in the southern and coastal regions of Texas. FM 1944GLB2 has similar agronomic characteristics to FM 1740B2F, with a slightly later maturity and improved yield potential and fiber quality.
FM 1944GLB2 has shown strong results in many trials in the geography, including in Bayer CropScience Cotton Agronomic Performance (CAP) trials, which are managed locally by farmers using their own preferred management practices, for real-world results.

Proven Technology
In 2011, cotton farmers in the Southwest planted three FiberMax GlyTol varieties – FM 2011GT, FM 9101GT, and FM 9103GT; and two FiberMax GlyTol LibertyLink varieties – FM 9250GL and FM 2989GLB2. Callaghan said that GlyTol and GlyTol LibertyLink traits demonstrated excellent crop tolerance with no plant injury to labeled rates of glyphosate approved for use over the top of cotton.

Jason Poole, of Quanah, Texas, planted the FM 2989GLB2 in 2011 so that he could use both Ignite and glyphosate to control problem weeds. Poole said the FiberMax variety with the GlyTol LibertyLink stacked trait offered a great solution for one of his fields that was heavily infested with morningglories. He experienced excellent weed control with the GlyTol LibertyLink system, with no crop injury in the field.

“We had so many morningglories in the field, it seemed like they were pushing the ground up,” Poole said. “We used both glyphosate and Ignite, and it cleaned everything up. The Ignite fried everything in the field but the cotton – it worked great. When we stripped the field, we didn’t see one morningglory.”

Farmers like Poole who plant the new FiberMax varieties with GlyTol and LibertyLink traits in 2012 can have confidence in the trait and variety performance because of extensive testing in trials and in the field. Callaghan said that Bayer CropScience developed these new traits and trait packages with the farmer in mind and offers the tools and resources to help maximize their efficiency.

“As the industry leader in bringing new cotton traits and trait packages to the market, Bayer CropScience understands that these solutions must help meet needs and solve problems for U.S. farmers,” Callaghan said. “These technologies have been tested repeatedly and demonstrate complete tolerance to glyphosate and Ignite herbicides, and the varieties give farmers the high yield potential they expect from Bayer CropScience.”
