Background Clubroot, caused by Plasmodiophora brassicae, is an important disease of crucifier crops. Since its discovery near Edmonton in 2003, clubroot has spread rapidly in Alberta, and is becoming a serious threat to canola production in Western Canada. The disease produces a range of symptoms, but early infection on the main root has the biggest impact on plant development and yield. Current canola cultivars are highly susceptible [1], and developing cultivars with lasting resistance may prove to be a challenge. Good agronomic practices may reduce disease spread, but their impact is generally insufficient for disease control especially when used alone.
