Glyphosate-resistant kochia has started showing up in more of Western Canada, and as with other cases of resistance, it’s becoming evident you can’t rely on a single tool for too long. Minimizing resistant weed populations requires an integrated or diverse approach. The crop itself must help make survival difficult for potentially resistant weed seedlings, explains Rob… 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

China imports about one-third of the canola grown in Canada. It’s critical Canadian canola meet the requirements for selling into the Chinese market. That’s why the Canola Council of Canada is advising against the use of quinclorac herbicide on canola in 2016, explains Brian Innes, vice president of government relations for the CCC, in this Canola School… Read More

According to speakers at last week’s Canola Galla in Penhold, AB, a single gram of soil (roughly the size of a Smartie) can contain hundreds — if not thousands or even millions — of resting clubroot spores. And, those resting spores can survive up to 20 years in the soil, spreading by catching rides on wind, water,… Read More

As a diverse set of volunteers in the agriculture industry, it’s hard to assign a worth to the work beneficial insects accomplish, but their absence can speak volumes, if you’re listening. To showcase that, Jim Broatch, pest management specialist with Alberta Agriculture and Rural Development, talks root maggots in this Canola School, and how an insecticide application… Read More

Unless it’s too late and you’ve already found clubroot symptoms in your canola, you won’t know whether you have it without getting tested. This Canola School episode focuses on testing for clubroot and how to go about determining whether clubroot spores are present in the soil. Finding the nasty soil-borne disease when spore loads are still low… Read More

Rotation is generally a critical part of mitigating any disease resistance problem. When it comes to preventing the breakdown of resistance in blackleg-resistant canola varieties, the first line of defence is an extended crop rotation with non-host crops. Beyond that, growers can also rotate the canola varieties they’re growing, suggests Anastasia Kubinec, oilseed specialist with Manitoba Agriculture,… Read More

Brassicogethes aeneus, commonly referred to as the pollen beetle and formerly known as Meligethes aeneus, is a major pest of canola in countries like Scandinavia, and, is now present in eastern Canada. And, though they are not yet a problem in western Canada, entomologists are suggesting we become familiar with what to look for. “One nice thing… Read More
