Key points

• ––An outbreak of sclerotinia stem rot is highly dependent on the season.
• Prolonged wet or humid conditions during flowering favour the disease.
• ––Consider past outbreaks of the disease as a guide to potential yield loss.
• ––Avoid growing canola in paddocks with a history of sclerotinia stem rot over the past four years, or in adjacent paddocks.
• ––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.
