Changes to canola disease labeling systems, protocols and cultivar screening – which all work toward ensuring high quality canola can be produced with minimized disease pressure – are covered by the pathology sub-committee of the Western Canada Canola/Rapeseed Recommending Committee (WCC/RRC). A recent sub-committee meeting on February 2 included discussion and changes on blackleg, clubroot and verticillium stripe…

Scientific research in Western Canada shows lower yields for canola in short rotations. Blackleg (shown above), clubroot and many other factors can cause this yield loss…

Soil sample the fall after canola harvest or the spring immediately following. This gives galls time to break down and release spores. If sampling this fall, target fields that are going into canola next year…not fields that were in canola this year…

Canola grower organizations in Saskatchewan, Manitoba and Alberta encourage farmers and agronomists to do more field testing… -
This article runs through a series of questions and scenarios, a bit like "choose your own adventure", to help farmers and agronomists come up with an appropriate management plan for each situation… -
You have been actively scouting and found clubroot early. The disease is confined to “patches” or small areas in your field, typically around field entrances, drainage paths or low spots in the field. Here’s what to do with them… -

That is why hybrids with clubroot resistance (CR) can still have clubroot galls…
