West Texas cotton farmers will have three new varieties with season-long in-plant tolerance to glyphosate herbicide available for 2011.

Bayer CropScience announced Thursday (Oct. 1) that final approval for their GlyTol varieties has been received and that three FiberMax varieties—FM 9101GT, FM 9103GT and an experimental variety not yet numbered—will be available next year.

“This is big for West Texas growers,” said Paul Callaghan, Global Cotton Traits Manager for Bayer CropScience. Callaghan said GlyTol varieties offer “optimal crop safety with a wide window of application. This allows farmers to decide what glyphosate product they want to use and what herbicide trait tolerance they prefer,” he said at a cotton production field day at the company’s Idalou, Texas, breeding station.

Bayer CropScience had planned to release these varieties for 2010 planting but delayed approval from Japan, a key trading partner for U.S. cotton, prevented a 2010 launch.

Callaghan said the 2011 release will be “a significant launch.”
