University of Manitoba research finds verticillium stripe in canola can break down blackleg resistance, creating challenges for disease management and yield protection on the Prairies.

Verticillium may undermine canola blackleg resistance
Verticillium stripe may compromise blackleg resistance protection in canola, new research out of Manitoba suggests
Producers weigh pros and cons of blackleg test
Race identification offers canola growers a precision-level guide to the exact resistance that they need, but will it work?
By now many canola producers have heard about race-testing blackleg samples. It’s a precision testing practice that recommends the canola variety needed to fend off different “races” of blackleg, the fungal crop disease costing Canadian canola producers hundreds of millions of dollars a year. One might look at it as another tool to integrate into […] Read more
Blackleg was brutal this year
WINNIPEG — The wet spring on the Prairies provided nearly “perfect” conditions for blackleg to develop in canola crops. That’s why 2024 will likely become the worst year on record for the disease in Saskatchewan. “Ninety-two percent of crops we surveyed in Saskatchewan in 2024 had at least trace levels of blackleg,” said Alireza Akhavan, […] Read more
Blackleg gene tests questioned
Glacier FarmMedia – Genetics are the tools of choice to minimize losses from blackleg, but there are signs that tried and true resistance genes might not be packing the same punch in every infected field. The fungal disease remains one of the most prevalent threats for canola, and gained particular traction this year after a […] Read more
Scout for fungal diseases in the fall
Harvest is a good time for producers to see how much sclerotinia slipped through the control cracks during the season
Glacier FarmMedia – Canola growers can evaluate levels of sclerotinia in their fields when it’s time to swath the crop, and the Canola Council of Canada says that’s the ideal time to scout. Sclerotinia is typically one of the top canola diseases on the Prairies, although disease surveys found few infections in Manitoba last year. […] Read more
Research gets a leg up on blackleg
Glacier FarmMedia – Results of a recent study by researchers in Manitoba and Alberta could help growers fight blackleg disease in canola more effectively. The study was done by a team of researchers at the University of Manitoba led by Dilantha Fernando, a professor in the school’s plant science department. They were joined by Michael […] Read more
It’s time to scout for blackleg and verticillium stripe
Diseases that are present in fields today will determine how long the crop rotation should be, as well as which canola hybrid to use
Canola farmers need to tackle fungal diseases head on by walking through their fields and learning firsthand the extent of the problem, said an expert. The idea behind scouting isn’t to protect this year’s crop from blackleg and verticillium stripe, said Courtney Boyachek, an agronomy specialist with the Canola Council of Canada. “But it does […] Read more
Blackleg’s genetic secrets revealed
Agriculture Canada researchers have made a breakthrough likely to help canola growers manage one of their biggest disease threats. Researchers have sequenced 162 races of the blackleg pathogen that are prevalent in Western Canada and with that knowledge they hope to provide growers with new tools for better managing the disease. Blackleg was first detected […] Read more
