University of Alberta researcher Victor Manoli tours International Clubroot Workshop delegates through his research work at Alberta’s Crop 
Diversification Centre North. Manoli has infected these plants with clubroot spores to enable future study.

No silver bullet for international disease

Scientists from around the globe met in Edmonton to discuss the latest on clubroot

The world’s top canola researchers and agronomists met in Edmonton in early August to talk about their work on the pathogen that’s lowering canola yields throughout Alberta and spreading to the rest of the Prairies. While researchers at the International Clubroot Workshop discussed the scientific research underway, farmer delegates were disappointed to hear there is […] Read more



Six steps to help prevent clubroot in canola

Six steps to help prevent clubroot in canola

Back in 2013, John Guelly discovered some dead canola plants with ominous-looking root galls at his Westlock-area farm. But even though clubroot was already known to be in his area, he hadn’t seen it himself, and he wasn’t sure what it looked like. People were secretive about the disease, he told farmers, agronomists and other […] Read more

Herbicide resistance continues to grow on the Prairies, but so will the list of management techniques to keep weeds such as wild oats at bay.

Reporter’s Notebook: How will we be farming in 20 years?

Lisa Guenther points to two agronomic problems shaping our future cropping plans

Agriculture has undergone big changes in the last century. Yesterday’s farmers would be amazed by the technology contained in a tractor and seeder these days, or by the vaccines that protect livestock from disease. Or even by the phones we tuck into our back pockets, and occasionally drop in the muck. It’s an interesting exercise […] Read more


When scouting for clubroot, one area to check is downwind of grain bins, Dan Orchard says.

Clubroot is coming to a field near you

The stakes are high, as clubroot has defeated resistant canola varieties and continues to spread

Dan Orchard has a blunt message for Saskatchewan canola producers. “I’m quite convinced that clubroot will come to your farm. It’s just too hard to keep it away,” said Orchard, agronomy specialist for central Alberta for the Canola Council of Canada. Orchard was speaking at the Saskatchewan Oilseed Producers meeting, organized by SaskCanola, SaskFlax, and the Sask. […] Read more

Reporter’s Notebook: Removing the stigma of clubroot

Reporter’s Notebook: Removing the stigma of clubroot

If we’re going to deal with clubroot, we need to consider the psychological issues

Back in 2015, I was in Australia, talking to farmers and others in agriculture about how they were handling herbicide resistance. Australian farmers have the unenviable task of dealing with weeds that are resistant to several modes of action. The country ranks number two globally for the number of herbicide-resistant weeds. During that trip, Brad […] Read more


Clubroot can damage more than just the bottom line

Clubroot can damage more than just the bottom line

Along with economic and agronomic problems, clubroot causes emotional damage

Clubroot is a potentially devastating disease for canola growers in Western Canada. Severely infested fields may not be able to grow canola in the foreseeable future. Less-severe fields may see yield drops without a change in farming practices. That adds up to a financial hit for affected farmers. But while the economic and agronomic realities […] Read more

Tips to help manage clubroot proactively, not reactively

Tips to help manage clubroot proactively, not reactively

Clubroot continues to spread. Don’t be too sure it won’t happen to you

Clubroot is rapidly spreading across Western Canada. Whether or not it’s in your fields, all canola growers need to be concerned about clubroot. Once a field is infected, clubroot will always be present, so preventing the spread of the disease is critical. A clubroot infection, in good environmental conditions, can devastate a canola field and […] Read more


Managing fungicide resistance

Managing fungicide resistance

Your risk of resistance will depend on the disease you have and the fungicide you spray

Should western Canadian farmers be concerned about fungicide resistance? And if so, how should they manage it? Fungicide resistance shares some fundamentals with herbicides, says Jared Veness, field marketing manager at Bayer Crop Science. By applying fungicide, farmers are applying selection pressure to a pest. Within that pest’s population, there are likely individuals with mutations […] Read more
