Diseases

Canola plant disease can have a huge impact on canola yield and longevity, so effective scouting strategies, proper identification and accurate assessment of diseases is crucial to successful canola crops. In addition to blackleg, clubroot and sclerotinia stem rot, diseases such as alternaria, aster yellows, root rot, seedling disease complex and verticillium stripe (amongst others) should be understood in order to be properly managed for a healthy, productive canola crop.
