Verticillium may undermine canola blackleg resistance
Verticillium stripe may compromise blackleg resistance protection in canola, new research out of Manitoba suggests
Researchers scramble to understand verticillium in Canada
While research into verticillium stripe is still in its infancy, agronomists are recommending crop rotation and better field practices
Verticillium is a newcomer among Canadian crop diseases, and according to Justine Cornelsen, agronomic and regulatory services manager with BrettYoung Seeds, researchers still have much to learn about it. “It was first identified on a farm south of Winnipeg in 2014, but it has now been identified in many other production regions,” she says. As […] Read more
A crash course on verticillium stripe
It’s important to know how to identify this newcomer to western Canadian canola crops and distinguish it from other diseases
Verticillium stripe of canola is causing yield loss in Manitoba and probably other areas of the Prairies. And it’s getting worse. The disease, caused by the Verticillium longisporum pathogen, was first reported in Manitoba in 2014. In 2015, Canadian Food Inspection Agency surveyors found the pathogen in six provinces, including all three Prairie provinces. The […] Read more
Keep verticillium stripe in focus this year
Practical Research: Don't let the fungi hitchhike between fields on your equipment -- or anyone else's
Where did such a destructive disease come from? Verticillium stripe was first reported in Manitoba in 2014, some 10 years ago. The fungus, Verticillium longisporum, has now been confirmed present in six provinces: British Columbia, Alberta, Saskatchewan, Manitoba, Ontario and Quebec. In a survey in 2023 across Manitoba, verticillium stripe was found in 38 per […] Read more
Canola’s least wanted
Experts discuss pests and pathogens canola growers will want to watch for in 2024
Flea beetles pose one of the greatest risks to yields for canola growers in Western Canada. A 2022 survey conducted on behalf of the Canola Council of Canada bore that out. Some 91 per cent of growers who participated in the survey identified flea beetles as the greatest economic risk to their crops. That’s likely […] Read more
Researchers to put numbers to verticillium yield loss
The team behind blackleg and clubroot yield loss models tackles the newer canola disease
Glacier FarmMedia — Canola industry leaders have been worried about verticillium stripe and its impact on crop yields for several years. Reports out of Europe suggest the fungal disease could cause losses of 10 to 50 per cent on oilseed rape. However, extreme losses are usually confined to a small number of fields in England […] Read more
Disease testing uptake low despite benefits
Canola disease tests help growers better manage their fields
Canola disease testing is available free of charge in much of the Prairies, but uptake among growers and agronomists remains relatively low, according to industry officials. In Manitoba, the Pest Surveillance Initiative (PSI) lab has been offering free clubroot testing since 2014. The Manitoba Canola Growers Association lab also offers free blackleg and verticillium stripe […] Read more
SaskCanola expands disease testing program
Verticillium stripe added to the lineup of free initiative
A program that offers free canola disease testing to producers in Saskatchewan has widened its scope. The disease monitoring program, offered by SaskCanola in conjunction with the Saskatchewan agriculture department, is free to producers across the province. Blackleg and clubroot testing have been available through the program for the past few years but this is […] Read more
Take verticillium stripe in canola seriously
A Manitoba farmer warns others about the threat this disease poses to canola production
Last year, Collin Shirtliff knew the threat to his canola crops posed by verticillium stripe but he wasn’t overly concerned. However, that changed late in the summer when he began harvesting the crop on the 3,600-acre farm he and his family operate near Starbuck, Man. What looked like an extremely promising crop weeks earlier suddenly […] Read more
