“Syngenta receives EPA registration for 2 convenient refuge in a bag trait stacks featuring top performing insect control.” Agrisure Viptera® 3220 E-Z Refuge® ” trait stack offers dual modes of action for control of multiple above-ground lepidopteran pests and corn borer. Agrisure® 3122 E-Z Refuge trait stack is intended for use in areas where corn rootworm and lepidopteran pest management are primary concerns. Products feature 5 percent blended refuge in a bag for convenience and easy compliance. What the 2 traits have in common: glyphosate tolerance, and in cotton-growing regions, you will need to plant a supplemental 20 percent refuge. The 2 traits will be available from Syngenta’s Garst®, Golden Harvest® and NK® seed brands for the 2013 planting season.
