Resistance Management Recommendations for Modes of Action not covered by FRAC Working Groups

This section contains FRAC approved company resistance management recommendations for fungicide MoAs not covered by an active working group. Please refer to the FRAC Code List for important comments on resistance management.

• Which Fungicides belong to the same FRAC MoA Group. Fungicides of the same FRAC MoA Group are expected to demonstrate a degree of cross resistance once field resistance arises. They are thus not seen as suitable mixing or alternating partners for resistance management purposes.
• The intrinsic risk of the MoA group, to be used for resistance risk analysis of fungicides (‘low’, ‘medium’ or ‘high’); which defines the need for resistance management.
• Comments on known (molecular) resistance mechanisms and resistant pathogens.

For some Mode of Action Groups the manufacturers provided FRAC with recommendations:
