With the cooler soil temperatures we’ve been seeing across Western Canada, unwanted pests are beginning to show up in some fields. Alberta Agriculture and Forestry Insect Management Specialist Scott Meers says that early on in the season we should be keeping our eyes out for stand establishment insects such as cutworms and wireworms. There have been a… Read More

Canola seed in Canada could soon come with a label describing the variety’s blackleg disease resistance package, similar to the labeling system used in Australia. After around four years of discussions between seed companies, researchers, and growers, an agreement-in-principle has been reached on blackleg resistance labeling, says Clint Jurke, agronomy director with the Canola Council of Canada,… Read More

Seed companies are turning to new sources of resistance to protect canola against blackleg disease, as the pathogen population in Western Canada has adapted over the years. Until recently, most of the varieties marketed as “blackleg resistant” relied on what’s known as the Rlm3 gene, explains Sakaria Liban, pathologist with DL Seeds, in this episode of… Read More

The clubroot story in Western Canada continues to be written as researchers are finding additional strains of the pathogen that are capable of overcoming genetic resistance. So far, 13 new variants have been identified since the breakdown of resistance was first confirmed in 2013, explains Stephen Strelkov, plant pathology researcher at the University of Alberta. “We think resistance… Read More

There’s no long-term trend talk of any agriculture commodity sector, it seems, that doesn’t include at least some reference to China. After all, it’s not just a populous country, it’s a huge economic driver and consumer of Canadian agriculture products. Imagine, then, what it would mean to have the Chinese market closed, a market worth… Read More

Canola seed companies are releasing more varieties with claims they have reduced susceptibility to sclerotinia, but how do they determine those ratings? Coming off a season with high sclerotinia pressure, what does it mean if a variety is labelled as ‘partially resistant’? In 2011, the Western Canadian Canola/Rapeseed Recommending Committee started searching for a test that… Read More

With a smartphone in their pocket, every farmer, farm employee, or agronomist is now also a photographer. The ability to share pictures from the field has dramatically improved how farmers and agronomists communicate and diagnose issues. However, the information gleaned from a cellphone photo can only be as good as the original picture. A poor photo won’t tell… Read More

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
