Summary:

A wilt disease previously unreported in North America was observed in the Peace River and north east regions of Alberta beginning in 1999. The disease induced chlorosis, stem necrosis, vascular discolouration and premature desiccation in Brassica napus and B. rapa. This disease could become a serious threat to canola production in Canada.
