Bayer CropScience
Bayer CropScience is evaluating four Bollgard II/Flex and four LibertyLink/Bollgard II varieties for 2010 release. According to Jeff Brehmer, the LibertyLink technology can address the growing glyphosate-resistance issue in cotton fields east of Texas. “We look to enhance or expand what we’ve found in FM 1845LLB2 and FM 1735LLB2. The LibertyLink system with Ignite herbicide has proven to be very successful. One of the key things we see is that farmers spraying the right rate at the right time are highly satisfied with the results.”
