Verticillium stripe — a disease first discovered in Western Canada in 2014 — appears to be taking advantage of the stress to canola plants caused by an old, familiar disease pathogen. While research to understand Verticillium longisporum in the Prairies is still in its early stages, there’s a hypothesis that its prevalence in a canola… Read More

It’s been six years since the disease we now call verticillium stripe was discovered in canola in North America. First identified on a research farm in Manitoba in 2014, a Canadian Food Inspection Agency (CFIA) survey the next year found the pathogen, which can cause striping symptoms on canola stems, in six provinces — from… Read More
There’s a new name for the canola disease that first showed up in Canada in a research plot in Manitoba in 2014. Caused by the fungus Verticillium longisporum, the disease was referred to by its common name in Europe: verticillium wilt. The problem is it doesn’t appear to cause wilting in canola. “The symptoms that we’re… Read More
Editor’s note: The Canadian verticillium stakeholders committee has decided to call the disease caused by Verticillium longisporum “verticillium stripe” instead of “verticillium wilt.” This story has been updated to reflect the new terminology. The canola industry is in the early stages of understanding what it’s up against with a new fungal disease. Verticillium stripe (previously… Read More
Now that Verticillium longisporum has been found in Canada, the Canadian Food Inspection Agency is working on getting a handle on the distribution of the new disease threat to canola. The verticillium wilt pathogen, which has caused significant economic losses in Europe’s rapeseed crop, was found in a canola trial plot at an undisclosed research location in… Read More
It’s too early to say how big a problem verticillium wilt could become for the Canadian canola industry, but it should be on the radar for growers, says the crop pathologist taking the lead on the new disease issue within Manitoba Agriculture. As reported by Real Ag last week, the first known case of Verticillium… Read More
It’s rare to find a western Canadian farmer who doesn’t have a tale to tell of the roaring comebacks canola has made in a growing season. Sure, there have been some wrecks — wicked windstorms that flip swaths or hail that leaves nothing but sticks — but the “Cinderella crop” (you’ve heard the song, right?)… Read More
Editor’s note: This story was updated on Thursday, January 8th with additional information from the CFIA about the location of the case of verticillium wilt in canola. The first North American case of a disease that has caused serious economic losses in Europe’s rapeseed crop has been found in a canola trial plot in Manitoba…. Read More
