Resistance Management Strategy for:
Group 11 + 3 fungicide mixture products
- Treat as a Group 11 fungicide for resistance management purposes.
- Apply only as a protectant treatment.
- Do not apply more than three sprays, or one third of the total sprays (whichever is the lower).
- Do not apply more than two consecutive sprays.
- Follow consecutive applications with two applications of fungicides from a different Mode of Action group(s) before using the product again in the current or following season.
Group 3 (triadimenol) fungicide
- Apply before disease becomes established.
- Tank mix or alternate with a product that has a different Mode of Action.
- Do not apply more than 4 sprays of triadimenol per crop.
Group 7 SDHI (Succinate dehydrogenase inhibitors)
- If applying Group 7 fungicides, DO NOT apply more than two consecutive sprays before changing to another group. DO NOT apply more than three Group 7 sprays per season. If consecutive sprays are used, then use the same number of sprays of an alternative group before using another Group 7, including sprays in consecutive seasons.
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
