Resistance management strategy for: 

Group 1  Benzimidazoles; 
Group 2  Dicarboxamides; 
Group 3  Demethylation inhibitors (DMI); 
Group 4  Phenylamides (PA); 
Group 7 (N3)  Succinate Dehydrogenase inhibitors (SDHI); 
Group 7 + 11  SDHI + Quinone outside inhibitors (QoI); 
Group 11  QoI; 
Group 11 + 2  QoI + dicarboxamides; 
Group 11 + 3  QoI + DMI; 
Group 12  Phenylpyrroles (PP); 
Group 14  Aromatic hydrocarbons (chlorophenyls and nitroanilines); 
Group 21  Quinone inside inhibitors (QiI); 
Group 28  Carbamates; and 
Group 33  Phosphonates. 

 

Guidelines 

  • Fungicide groups that are classified as medium to high risk for fungicide resistance development; Groups 1, 2, 4, 7 (N3), 11 and 21 should be rotated as a key feature to reduce the development of resistance. 
  • Do not apply consecutive sprays of fungicides from the same activity group, unless mixed with a registered fungicide from a different mode of action group with no known resistance. 
  • Group N3 nematicides are also classified as Group 7 fungicides and consecutive application should be avoided, even if targeting different pests/pathogens. 
  • If consecutive sprays are applied of fungicides from a high-risk fungicide group (i.e. Group 1, 2, 4, 7, 11 or 21) they must be followed by at least the same number of applications of fungicide(s) from a different group(s) before the same high-risk fungicide is used again.

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 26 June 2025. All previous versions of this strategy are now invalid.
