Groups 1, 4, 11 and 12 fungicides
For resistance management, please note that Maxim Quattro seed treatment contains Groups 1, 4, 11 and 12 fungicides. Any fungal population may contain individuals naturally resistant to Maxim Quattro seed treatment and other Group 1, 4, 11 or 12 fungicides. A gradual or total loss of pest control may occur over time if these fungicides are used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.
