Almonds – Rust

Crop(s):          Almonds

Disease(s):     Rust

Resistance Management Strategy for:

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

1. Do not apply consecutive sprays of solo products containing Group 7 or 11 if applied solo. Consecutive sprays include mixtures containing Group 7 or 11. If applying Group 7 7 or Group 11 fungicides in mixtures e.g. Group 11+7, consecutive application is allowed. Do not apply more than two consecutive sprays before changing to another group.
2. If two consecutive sprays of Group 3 or Group 11+3 fungicides are used, then use the same number of sprays of an alternative group(s) before using another Group 3, including sprays in the following seasons.
3. If applying Group 7 or Group 11 fungicides in mixtures e.g. Group 11+7. Do not apply more than two consecutive sprays before changing to another group.
4. Rotate with products from Groups M.
5. 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.
6. The spray program should be considered and the strategy applied on a whole-orchard basis.
