Changes to canola disease labeling systems, protocols and cultivar screening – which all work toward ensuring high quality canola can be produced with minimized disease pressure – are covered by the pathology sub-committee of the Western Canada Canola/Rapeseed Recommending Committee (WCC/RRC). A recent sub-committee meeting on February 2 included discussion and changes on blackleg, clubroot and verticillium stripe…

The fungal pathogen Verticillium longisporum causes stem cross-section discolouration that can look somewhat like blackleg and bleaching of the stem that can look somewhat like sclerotinia stem rot. But these diseases are all quite different in terms of yield risk and management, so it’s important to be able to tell them apart… -
If whitened canola stems are peeling and have black spots under the peeled layer, the cause is likely verticillium. Seeing this? Please get it checked out and let us know. We're trying to find out how widespread the disease is… -
Disease scouting long after swathing is not usually the most accurate, as saprophytic organisms — those that feed on and break down dead material — move in fast and cloud the identification process. Verticillium is one disease that can be more obvious and easier to identify after cutting a canola crop… -
Verticillium wilt of canola has been renamed verticillium stripe. Why? The pathogen in question, Verticillium longisporum, does not appear to produce wilt symptoms in canola, so the “wilt” name used to describe the potato and sunflower disease caused by the related fungus V. dahliae infection does not apply.
