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
Raising the profile of verticillium stripe
Identifying the new-ish fungal threat on the block can be tricky because it resembles blackleg
Reading Time: 4 minutes Conditions weren’t ideal for verticillium stripe this year but the Canola Council of Canada says growers should stay alert when it comes to the disease. “Verticillium stripe is a soil-borne pathogen and it overwinters in the soil,” said Courtney Boyachek, agronomy specialist and verticillium stripe lead with the council. “Last year was a bad year […] 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[...]

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[...]

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[...]

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[...]

Verticillium wilt makes jump to Canadian canola
A Manitoba canola field has been confirmed as the first in North America with Verticillium wilt, a fungal disease well known to northern Europe’s canola and vegetable growers. With no seed treatments or foliar fungicides yet registered against it — and with no resistant canola varieties available — the disease, if here to stay, may[...]

Plant diseases to look for in 2014
Provincial officials say the story for 2013 was of extremely localized disease outbreaks and the one for this coming year could be the arrival of new threats
Reading Time: 4 minutes Last year underscored the need for timely scouting for crop diseases. “Disease patterns matched the weather,” provincial pathology researcher Mike Harding said at last month’s 2014 Irrigation Update conference. “Different conditions led to serious disease issues in one area and virtually none just 20 miles away.” For example, cereal leaf spot diseases were widespread especially[...]
