Any illusions that Saskatchewan had some sort of secret immunity to clubroot should be put to rest with new findings just announced by SaskCanola. According to a press release, 37 fields in the province have been confirmed to have had clubroot symptoms.
Up until this time there have been relatively few fields with clubroot identified in Saskatchewan, even though Alberta has been dealing with very high levels for several years. This may have led to a certain amount of complacency among some Saskatchewan and Manitoba canola growers.
Saskatchewan initiated an ambitious 1,800-field survey this past summer in order to get a better handle on clubroot levels and distribution. Some of the new clubroot findings came out of this survey and others from farmers and agrologist as they scouted fields this past summer, according to SaskCanola.
The Clubroot Survey results are still being compiled, and soil samples are being analyzed at the province’s pathology lab. Once the results are confirmed the full report and distribution map should be released in late 2018 or early 2019.
There’s one clear message in all of this surveying and testing — Saskatchewan fields have clubroot; there is no such thing as immunity. Farmers need to take additional measures to protect their farms and their livelihoods from this disease.
