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.

Researchers scramble to understand verticillium in Canada
Disease is a relative newcomer to Canada and has been the subject of little research globally
Early bird may dodge verticillium woes in potatoes
Pushing a problem field to the front of the planting queue may help limit infection
Verticillium wilt is a problem for a lot of crops in Manitoba, including canola, sunflowers and alfalfa. In potatoes, the fungus Verticillium dahlia is the main cause of potato early die complex. In a 2021 interview with the Co-operator, Mario Tenuta, University of Manitoba soil scientist and main investigator with the Canadian Potato Early Dying Network, suggested the condition
Fall field scouting can highlight diseases
Verticillium and Goss’s wilt are both easily spotted near or after harvest
Field scouting doesn’t stop with the combine, but it does become more specific, according to Dr. Vikram Bisht, pathologist with Manitoba Agriculture. “Usually, to scout for soil-borne pathogens is not an easy thing because you have to do a lot of laboratory work, but if you have the pathogens which survive in the crop residue
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
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
A canola disease that still lingers
More than 90 per cent of surveyed canola fields had blackleg
While many canola growers are worrying about new diseases like verticillium wilt or the growing threat of clubroot, it may be an old threat that causes them the most problems in the coming seasons — blackleg. “We’ve seen a continued trend of increased prevalence,” said Angela Brackenreed, speaking at Brandon’s Keystone Centre during Ag Days.
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
Disease a North American first
Where it came from isn’t as important as how it will be contained when it comes to verticillium wilt in canola
Manitoba prides itself on welcoming newcomers, but the canola sector won’t be rolling out the welcome mat for this one — verticillium longisporum. The disease was discovered in a Manitoba canola field late last fall and visually identified at Manitoba Agriculture’s Crop Diagnostic Centre. That determination was later confirmed by molecular analysis at the National
Seed, equipment quarantined at wilt-stricken Man. farm
Seed and equipment are now under federal quarantine at a Manitoba farm where a crop pathogen never before seen in Canada made its first-ever appearance in North American canola. Without giving the farm’s specific or general location, the Canadian Food Inspection Agency said Friday it’s placed a quarantine order on seed from the farm at
