Resistance Management Strategy for:

  • Group 2 (Dicarboximide) fungicides; and

  • Group 9 (Anilinopyrimidine)

  1. If three or fewer Botrytis fungicide sprays are applied per crop, use only one spray containing a Group 9 fungicide.  If four to six sprays are applied per crop, use a maximum of two sprays containing Group 9 fungicides.  If seven or more sprays are applied per crop use a maximum of three sprays containing Group 9 fungicides.

    Avoid applying more than two successive sprays of a Group 9 fungicide, including from the end of one season to the next.

  2. DO NOT apply more than two consecutive sprays of a Group 2 fungicide.

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
