Disease(s): Powdery Mildew
Resistance Management Strategy for:
Group 3 Demethylation inhibitor (DMI);
Group 11 + 3 Quinone outside inhibitors (QoI) + DMI;
Group 7 Succinate dehydrogenase inhibitors (SDHI); and
Group 13 aza-napthalenes.
- Apply fungicides before disease becomes established.
- DO NOT apply more than four sprays of a Group 3 containing fungicide per crop.
- If applying a Group 7, 11 (or 11+3) or 13 containing fungicide, DO NOT apply more than two consecutive sprays before changing to another group. DO NOT apply more than three applications containing a Group 7, 11 (or 11+3) or 13 fungicide per season. If consecutive sprays are used, then use the same number of sprays of an alternative group before using another Group 7, 11 (or 11+3) or 13, which includes sprays from consecutive seasons.
