Pulse Crops – Grey mould (𝘉𝘰𝘵𝘳𝘺𝘵𝘪𝘴)

Crop(s):          Pulse crops

Disease(s):     Grey mould (Botrytis) and ascochyta

Resistance Management Strategy for:

Group 1                  Methyl benzimidazole carbamates;
Group 2                  Dicarboximide;
Group 3 + 11         Demethylaion inhibitors (DMI) + Quinone outside inhibitor (QoI);
Group 7*                Succinate dehydrongenase inhibitors (SDHI);
Group 7 + 3           SDHI + DMI; and
Group 7+12           SDHI + phenylpyrroles (PP).

  1. Do not apply more than two Group 1, 2, 3+11, 7+3 or 7+12 sprays in one season (including seed treatment).
  2. Do not apply more than two consecutive Group 1, 2 or 7 sprays, including from season to season and seed treatments. The final foliar spray of the previous season should be considered when planning which fungicide group to use in seed treatments and the first foliar application. Group 7 containing sprays should not make up more than one in every three of the spray program.
  3. If a Group 7 containing fungicide is used as a seed treatment, the first foliar fungicide used must not contain a Group 7 fungicide.
  4. 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.

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 14 July 2023. All previous versions of this strategy are now invalid.
