Canola – Sclerotinia

Crop(s):  Canola

Pest(s): Sclerotinia

Resistance Management Strategy for:
Group 2               (Dicarboximide);
Group 3               DMI (Demethylation Inhibitor);
Group 7               SDHI (Succinate dehydrogenase Inhibitors);
Group 7+3          (SDHI + DMI); and
Group 11+3        (Quinone outside Inhibitor + DMI).

  1. Fungicides should be used as protectant treatments, applied during flowering of the crop, prior to an infection period.
  2. DO NOT apply more than two applications per flowering period of Group 11 (or 11+3) or Group 7 (or 7+3) containing products for the control of sclerotinia in canola.
  3. DO NOT apply more than three applications containing Group 2 or Group 3 (or 11+3 or 7+3) fungicides per flowering period for the control of sclerotinia in canola.

Note: An application in the flowering period for the control of upper canopy infection (UCI) of blackleg should also be counted as an application for the control of sclerotinia, if conditions are conducive for sclerotinia infection or sclerotinia infection is already present.

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
