Resistance Management

For resistance management, Varro FX is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to Varro FX herbicide and other Group 2 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific to individual chemicals such as enhanced metabolism, may also exist. Appropriate resistance management strategies should be followed.

Contact your local Bayer representative at 1 888-283-6847 for any additional pesticide resistance management and/or integrated weed management recommendations for specific crops and weed biotypes.
