The window to control disease in canola is closed, so why scout? Well, because the period from podding to harvest is the easiest time to see diseases. And if you can identify which diseases are present, you can adjust your variety choice, crop rotation and fungicide use for subsequent years…

1. Have a plan to manage clubroot. Don't wait until clubroot manages you. Whether you're a farmer, agronomist, county/municipal staff, extension, or from the oil & gas industry, you need a clubroot management plan. A plan should include answers to the following: How will you quarantine a field? How will you plan your field work? When will you sanitize your…

Agronomists and other staff traveling from field to field are encouraged to use the following best management practices (BMPs) to avoid spreading clubroot-infested soil. 1. Park on the road or in a grassed approach. 2. Wear plastic or Tyvek disposable booties over existing footwear. 3. Rubber boots worn without booties must be cleaned before leaving the field…

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…
