Bayer CropScience has launched third generation GM cotton seed varieties FiberMax® in Brazil market for the 2014/2015 crop season. With the technology of GlyTol®-LibertyLink®-TwinLink® (GLT), FiberMax has three traits that promises a wide spectrum on controlling weeds and caterpillars.
According to Marcus Lawder, Strategic Marketing Manager of Cotton Seeds at Bayer CropScience, GLT® is the first integrated technology launched in Brazil with three important traits, which would bring more flexibility in preventive management, better plants development and better fiber yields.
GlyTol® brings tolerance of the cotton plant to herbicide glyphosate. It allows a big window of glyphosate application, offering more flexibility on herbicide application and reducing the number of applications needed.
LibertyLink® provides cotton plants tolerance to herbicides glufosinate ammonium (sold in Brazil under the brand Liberty®). LibertyLink® allows farmers apply glufosinate to control a wide spectrum of weeds, and provides non-selective chemical groups to combat weed resistance.
TwinLink® expresses two BT genes (Cry1Ab and Cry2Ae) for the control of lepidopteran caterpillars, cotton leafworm, tocacco budworm, fall armyworm, pink bollworm, and the looper.
The flexibility proposed by the technology enables that spraying are done at the best moment for weed management, instead of being limited to a specific stage of cotton growth, potentially reducing applications to efficiently control invasive weeds.
Lawder reported that the field experiments that took place in the last crop (2013/14) in Brazil with cotton GLT® demonstrated a 2% to 3% increase of fiber yields.
