Canola School: Reporting New Clubroot Infestations in the Fight Against the Disease


It’s certainly not a disease you want to find in your fields, but if you do, there are good reasons to talk about it — specifically, report it — says Michael Harding, research scientist with Alberta Agriculture and Forestry.

“If it’s the first time clubroot’s been found in the field, by reporting it, you can get help. You can get aid or assistance,” Harding says, in the following interview, referring to both equipment and advice. “It [also] gives us a better idea of where clubroot is, and where we need to be actively scouting for new infestations.”

Reporting instances of disease can also help provinces in surveillance efforts and education regarding clubroot resistance breakdown.

“Now that we’ve started to see the new variants of clubroot that are virulent on our formerly-resistant cultivars, it’s a really good idea to report those so that we’re aware of how quickly that’s happening, and can be putting management recommendations in place,” says Harding.

This is the first of two videos we filmed with Harding this month, surrounding clubroot. In this episode, we talk about the best time of the year to scout for the disease, what weeds might give us hints of disease development in non-canola years, how environmental conditions impact symptom development and — as mentioned above — why reporting first-time sightings might be a good idea.
