What’s your biggest disease threat this year?

The weather will tell the tale, but there’s one crop disease 
‘producers should be thinking about and preparing for’

Predicting crop disease problems is like taking a shot in the dark at a moving target. “For disease to develop, we need certain weather, certain hosts, and certain pathogens, so it can really be like looking into a crystal ball,” said Stephen Strelkov, a professor and researcher at the University of Alberta. “As a result, […] Read more

These clubroot galls are small but this is exactly what you should be looking for when scouting because your best chance to manage an infestation is to detect it in its early stages.

It’s been perfect conditions for clubroot

Wet conditions not only increase spore counts but may also favour development of strains able to overcome resistant varieties

This year’s wet conditions may leave a nasty legacy — more clubroot infestation and more strains of the pathogen able to overcome resistant varieties. “In the years where there is more wet weather, we expect to have more severe symptoms and more widespread infestation,” said Stephen Strelkov, a University of Alberta professor of plant pathology […] Read more


Extreme infestation may require extreme treatment

In really bad cases, putting a few acres into grass or forages may be the best way to contain clubroot pathogen 


Growers with extreme clubroot infestation are being told that the best option might not be to just stop growing canola for a while, but all annual crops in parts of a field. Seeding patches of heavily infested ground to grass or forages is now on the list of clubroot management practices recommended by the Canola […] Read more

Canola growers in the red, blue, and yellow counties are being urged to institute a “comprehensive management plan” to contain the spread of clubroot.

Canola growers get grim warning on clubroot threat

No varieties have strong resistance to new pathotypes, longer rotations are ‘the best management option left’

The Alberta Canola Producers Commission is urging producers to step up their efforts to contain clubroot in the province. “Since new data indicates some forms of clubroot resistance are no longer functioning well against new clubroot pathotypes in some of the heavily infested fields, we encourage you to consider a comprehensive management plan that includes all […] Read more
