LibertyLink Liberty Integrated Pest Management_2013 Seed Trait Technology Manual Part 5


Published on

LibertyLink cotton is equipped with LiberyLink trait that provides effective weed management and enables nonselective herbicide rotation. With GLyToL LibertyLink technology in cotton, it brings the ability for growers to make applications of either Liberty Herbicide or glyphosate. TwinLink paired with LibertyLink offers two-gene protection against worm pests.
