What do I need to know about blackleg branch canker?

Unusual blackleg symptoms were observed on canola stems and branches across southern Australia in 2014. Early-sown canola is more likely to be flowering and elongating during the peak blackleg infection window and suffer stem and branch cankers as a result.

Sowing time and variety resistance ratings in the Blackleg Management Guide can be used to minimise the impact of blackleg.

The article, Curious cankers confirmed as blackleg (PDF 1.6Mb), has more information about the outbreak and management options.
