  • 1. THE LIBERTYLINK TRAIT Liberty is a nonselective contact herbicide that IN CANOLA provides postemergence control of broadleaf weeds and grasses, including weeds resistant InVigor hybrids carry the LibertyLink trait, to glyphosate and multiple herbicide classes. which provides built-in tolerance to Liberty herbicide. Liberty kills weeds in days vs. weeks. InVigor canola hybrids with the LibertyLink Liberty herbicide with the LibertyLink trait trait are top performers, known for outstanding keeps weed management simple and allows yield and strong early season growth. They growers to continue farming efficiently. consistently deliver superior crop establishment, Liberty herbicide with the LibertyLink trait is uniform maturity and greater harvestability over the only nonselective alternative to glyphosate- many other hybrids. tolerant systems. InVigor LibertyLink canola hybrids are developed in high-yielding, strong-performing, WHERE TO FIND INVIGOR elite germplasm, which results in stable and LIBERTYLINK CANOLA consistent performance in the field, without LibertyLink trait technology is available in yield drag or lag. high-yielding, high-quality InVigor hybrids.
