From seedling issues to stand die-off, understanding the timing and symptoms of alfalfa diseases can help protect yield
Researchers scramble to understand verticillium in Canada
Disease is a relative newcomer to Canada and has been the subject of little research globally
Justine Cornelson of BrettYoung Seeds says verticillium is one reason Manitoba saw disappointing canola yields last year. The disease needs to be the subject of more research, since little has been done to date.
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
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
Four canola diseases to watch for
Is that canola crop afflicted by blackleg, root rot, both, or something else entirely? It’s a messy question farmers and agronomists encounter every year. Presenters tried to untangle those problems at CanoLAB in Vermilion this winter. Here are four diseases to watch for in canola fields this summer, and tips on diagnosing them.
No point in quarantine for verticillium wilt, CFIA says
Slapping federal quarantines on canola fields with verticillium wilt wouldn’t serve much purpose, since the yield-robbing fungi is already in all of Canada’s major canola-growing areas, the Canadian Food Inspection Agency says. While the agency itself is recommending against regulation, CFIA on Wednesday posted a draft of a risk management document on verticillium wilt, seeking […] Read more
Fungicide cleared to curb verticillium wilt in potatoes
A label expansion for Syngenta’s Aprovia fungicide, to cover additional soil-borne potato diseases, makes it the first fungicide in Canada approved to suppress verticillium wilt in potatoes. Fumigants have been potato growers’ only option against the crop disease until now, Eric Phillips, Syngenta Canada’s fungicides and insecticides product lead, said in a release Thursday. Verticillium […] Read more
Verticillium wilt found in Manitoba
Be on the lookout for this canola yield-stealer at the end of the season, when the plant begins to ripen
Verticillium wilt, caused by Verticillium longisporum, was detected in canola in Manitoba last summer. While verticillium wilt is common in northern Europe — it’s the number one disease in oilseed crops in Sweden — this was the first case of the disease in an oilseed crop in North America. What is verticillium wilt? Verticillium longisporum […] Read more
Manitoba canola pest lab backed for equipment, research
A new Manitoba lab with federal, provincial and canola industry backing has been opened with the goal of staying a step ahead of canola diseases such as clubroot and verticillium wilt. The federal and Manitoba governments on Thursday announced $969,000 for equipment, including a polymerase chain reaction (qPCR) machine, and $250,000 for research at the […] Read more
