Avocado and Mango – Anthracnose

Crop(s):              Avocado and Mango
Disease(s):         Anthracnose (Colletotrichum spp.)

Resistance Management Strategy for:

*Group 3       Demethylation inhibitors (DMI);
Group 7+11  Succinate dehydrogenase inhibitors (SDHI) + Quinone outside inhibitor (QoI);
Group 11       Quinone outside inhibitor (QoI).

  1. If applying Group 11 (including 7+11) fungicides, do not apply more than two consecutive sprays before changing to another group. Do not apply more than three Group 11 sprays per season within the field. If consecutive sprays are used, then use the same number of sprays of an alternative group before using another Group 11.
  2. *Do not apply more than four Group 3 sprays in a season. Apply no more than two consecutive sprays of a Group 3 fungicide alone.
  3. 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.

*Appropriate in mangoes only.

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 www.apvma.gov.au

The information given in this strategy is provided in good faith and without any liability for loss or damage suffered as a result of its application and use. Advice given in this strategy is valid as at 16 July 2021. All previous versions of this strategy are now invalid.
