How to protect clubroot resistance

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...

Annual soil tests improve nitrogen returns

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...

Understanding the cellular mechanisms of clubroot disease and developing a new form of clubroot resistance

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...

Mapping a route to clubroot resistance

Twelve molecular markers were identified that will be useful in breeding programs including gene pyramiding for durable clubroot resistance.
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,...

Manure-sourced P fertilizer increases crop safety

Science Edition 2015—Key Practice: Struvite shows promise as a phosphorus-fertilizer source. This study shows that struvite recovered from hog manure can match yields compared to monoammonium phosphate and provides higher seed-placed safety. Project title, Lead Researcher: “Can slow-release monoammonium phosphate and struvite improve phosphorus use efficiency and reduce seedling toxicity in canola?” Francis Zvomuya, University of Manitoba...
