The highest risk operation to introduce and spread clubroot is the one that moves the greatest amount of soil throughout the farm and across the countryside. Field equipment carries a lot of soil, which is why equipment sanitation is an important way to contain the disease. Others common ways to move soil include utilities companies working from field to field,…

These photos from canola plots grown in clubroot-infested soils in Quebec show how rotation, especially for MS and S varieties, improves yield. Rotation also plays an important role for growers relying on R varieties in clubroot infested fields. Short rotations using resistant varieties will select quickly for clubroot pathotypes that are not controlled by the genetic resistance. This can rapidly…

Two Manitoba fields surveyed in the canola disease survey in 2012 have been confirmed to have clubroot. This is no reason to panic. Clubroot is a manageable disease. Clubroot is expected to spread across the Prairies eventually, and clubroot was first detected in Manitoba vegetable crops in 1925. It is not a surprise to find it in canola fields. The…

Give the brand new online Canola Diagnostic Tool a pre-season test drive at www.canoladiagnostictool.ca. Start with a problem scenario that you encountered in a canola field in 2012, and work through the tool to see what potential causes it provides. Read the cause descriptions and “ways to confirm” to determine which cause is most likely…
