Clubroot (Plasmodiophora brassicae) is a critical disease in canola that threatens a crop that contributed $12.9 billion (2022) in exports to Canada’s economy [AB $4 billion]. By infecting the plant’s root, clubroot disrupts water and nutrient uptake, resulting in stunted growth, reduced seed quality, and significant yield losses of up to 50%.

RDAR, the Alberta Canola Producers Commission, and the Saskatchewan Canola Development Commission (SaskCanola) awarded $1.25 million to Dr. Stephen Strelkov, Professor of Plant Pathology at the University of Alberta, to lead an expert team in:

  • Breeding resistance into new crop varieties.
  • Developing new ways to control the pathogen.
  • Identifying clubroot resistance genes.

Which fields are good candidates for this test? Corn fields that have a history of manure, as well as fields that maybe have a previous legume, and it's a great tool for the cover crops to be able to detect if nitrogen is going to be immobilized. When should we be taking these samples? You could think about four to six weeks after planting, and you could think about your vegetative stages from V3 to V5.
