Although it’s been proven that high pH soil will not stop the spread of clubroot disease, liming has been used as a tool to curb the disease in other parts of the world. Early results from a research project underway in Alberta show raising the pH of acidic fields with lime could potentially aid in… Read More

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
Visible clubroot symptoms were first identified in a canola field in Alberta in 2003. It has since spread through much of the province, and by the end of 2014, it was present in 30 municipalities and into neighbouring provinces. It was also that year, that a pathotype of the disease observed the year earlier was confirmed… Read More
