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…

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…

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…

—All areas of the Prairies are at risk. Geography does not provide immunity to this disease. —Prevalence of sclerotinia stem rot has a direct correlation to above-average moisture. If a field has regular rains or high humidity or both from two weeks before flowering and through flowering, then infection will occur. If these conditions continue after flower, severity of the…

Most agronomists are also pressed for time, and may not be able to spend one to 2 hours a week scouting each canola field, but agronomists can supplement the time growers spend scouting, and provide experience and skills…
