Group 3 Demethylation inhibitors (DMI);
Group 7 Succinate dehydrogenase inhibitors (SDHI);
Group 7 + 3

Group 11


Quinone outside inhibitors (QoI);

Group 11+3 QoI + DMI; and
Group 11+7 QoI + SDHI.


Maximum recommended number of sprays which can contain Group:

  1. Do not apply consecutive sprays of products containing Group 7 or 11 if applied solo. Consecutive sprays include mixtures containing Group 7 or 11.
  2. If applying Group 7 or Group 11 fungicides in mixtures e.g. Group 11+7, consecutive application is allowed. Do not apply more than two consecutive sprays before changing to another group.
  3. If two consecutive sprays of Group 3 or Group 11+3 fungicides are used, then use the same number of sprays of an alternative group(s) before using another Group 3, including sprays in the following seasons.
  4. Rotate with products from Group M.
  5. No specific resistance management strategy has been developed for low-risk fungicides, including those in Group M and BM. These products should be included in a management strategy as per label recommendations.
  6. The spray program should be considered and the strategy applied on a whole-orchard basis.

CropLife Australia’s Resistance Management Strategies provide a guide for crop protection product rotation through product groups. The strategies are a useful tool that supports farmers’ adoption of resistance management. All crop protection products must be handled and applied strictly as specified on the product label or APVMA permits.

These Resistance Management Strategies do not replace product labels. They are a guide only and do not endorse particular products, groups of products or cultural methods in terms of their performance. It is important to check with the Australian regulator’s (APVMA) product database for contemporary information on products and active constituents. The database can be sourced through
