Science Edition 2015—Key practice: Following a diverse rotation reduces soil pathogen populations and disease pressure. However, crop rotation should only be one part of your integrated approach to disease management. Project title, Lead researcher: “Effect of crop rotation on canola seedling blight and soil pathogen population dynamics,” 2006-07, Sheau-Fang Hwang, Alberta Agriculture and Forestry Grower organization funder:...
Read More Science Edition 2015—Clubroot is a soil-borne disease caused by Plasmodiophora brassicae. It’s an emerging threat to canola production. Results of this study show that effective clubroot management relies on cultivar resistance in combination with management practices that reduce viable resting spore populations. lubroot is a soil-borne disease caused by Plasmodiophora brassicae. It’s an emerging threat to canola...
Read More Science Edition 2015—Key practice: Predicting how much nitrogen is reserved in the soil is difficult. Given its high cost in canola production, conducting an annual soil test on each field to determine appropriate rates is a good idea. The wild card is moisture supply throughout the growing season. Project title, Lead Researcher: “Long-term effects of different soil...
Read More Science Edition 2015—Key practice: Rather than using genetically resistant varieties or the application of soil amendments and fungicides, this study is working to develop a new, alternative approach to clubroot resistance by silencing pathogen gene expression within the plant itself. Project title, Lead researcher: “Genomics of Clubroot disease development in canola and development of in-plant RNAi to...

Science Edition 2015—Key practice: P. brassicae can rapidly adapt to the selection pressure provided by currently available clubroot-resistant canola varieties. For durable clubroot resistance, it will be important to stack resistance genes and rotate them in clubroot-infested fields. Project title, Lead researcher: “Studies on the genetic and molecular basis for clubroot resistance in canola,” 2010-15, Stephen Strelkov,...
