Understanding sclerotinia in canola locations

To provide information relating to managing sclerotinia stem rot in canola.

Key messages

(i) An outbreak of sclerotinia stem rot is highly dependent on the season. Prolonged wet or humid conditions during flowering favour the disease. (ii) Consider past outbreaks of the disease as a guide to potential yield loss. (iii) Avoid growing canola in paddocks with a history of sclerotinia stem rot over the past four years, or in adjacent paddocks. (iv) Well-timed fungicide treatments – when canola crops are at 20 to 30 per cent flowering stage – can be highly effective in reducing the level of infection.
