Switch to longer rotations, reduce soil movement, grow resistant varieties — the list of keys to managing against clubroot disease has become familiar for many canola growers in Western Canada, but an Alberta farmer with years of experience farming with high clubroot concentrations has another piece of advice: don’t be afraid to talk about it….

When we think of canola, we think Western Canada. And there’s no doubt that the prairies are the canola capital, but Meghan Moran, canola and edible bean specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs, reminds us that there are still canola growers in Ontario, too. While the all-time high of 90,000… Read More

As farmers finalize and consider their crop decisions for 2018 with a lot more detail, there are some developing conversations that are creating a bit of a stir among farmers, agronomists and industry. The debate over soybean acres is exciting, but the real concern is canola acres. Canola acres were a record 22.8 million acres… Read More

As clubroot disease spreads in Western Canadian soil, growers who have yet to see symptoms in their fields have a decision to make: when should they start growing varieties that are marketed as resistant to clubroot? “From the Canola Council’s perspective, ideally, we all start growing clubroot-resistant varieties early. We take a proactive approach and… Read More

SaskCanola is letting canola growers in the northwest part of the province know clubroot disease has been found at high levels in the region. “We’ve been advised that one new field in the northwest region of the province is heavily infested with clubroot,” says Janice Tranberg, executive director, in a statement issued Monday. “In response… Read More

Alberta’s Peace region has taken flack over the years for its tight canola rotations. The snow-canola-snow rotation was once a laughing matter, but after today’s announcement the joke is no longer funny. The Canola Council of Canada has announced that clubroot has been discovered in the southeast corner of the northern Alberta region. This changes… 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

Crop Production Services is releasing a canola variety it says offers the “first true” multigenic resistance to clubroot disease, including the new 5X pathotype found in Alberta. The Proven Seed-brand variety PV 580 GC was formally registered on October 23. “The CPS Canadian Research and Development team has invested heavily in discovering and breeding new… 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

After ramping up efforts to test for clubroot disease over the last year, Manitoba Agriculture, Food and Rural Development has confirmed the presence of the nasty soil-borne pest in 48 fields within the province. The provincial ag department has released an updated map showing positive clubroot cases by rural municipality (see below), while noting “positive findings… 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

Resistance to clubroot disease in canola is deteriorating across Alberta, according to research conducted by Alberta Agriculture and the University of Alberta. Multiple pathotypes are now suspected to be responsible for infecting canola varieties that were previously deemed resistant to the soil-borne disease. The presence of a different clubroot pathotype that could infect resistant varieties… Read More
