Fruit – Post-harvest diseases

Crop(s):          Fruit (post-harvest treatment)

Disease(s):      Post-harvest diseases

Resistance Management Strategy for:

Group 2                Dicarboximides;  
Group 3                Demethylation inhibitors (DMI);
Group 3 + 12       DMI + phenylpyrroles (PP);
Group 9                Anilinopyrimidines (AP);
Group 11 + 12     Quinone outside inhibitors (QoI) + PP; and
Group 12              PP.

  1. For the last pre-harvest spray, use a fungicide with a different activity group to the fungicide planned for use as a post-harvest treatment.
  2. Where alternatives are available, rotate to use as many different activity groups as possible.
  3. Do not dispose of unused dip solutions as a spray to crops or orchards.
  4. Do not dispose of unused dip solutions within or near the crop or orchard area.

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
