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...

Key practice: Managing cabbage seedpod weevils (when they reach thresholds) with a single insecticide application at early flower stage can reduce pod-stage abundance of lygus bugs and may increase yield by an average of 1.5 bu./ac. Project title, Lead researcher: “Management of lygus bugs and seedpod weevil in canola at the farm level,” 2010-14, Hector...
Read More 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...

Key practice: Where swede midge is a concern, seed as early as possible. Where swede midge can cause significant losses, consider B. juncea or S. alba varieties over B. napus. Project title, Lead researcher: “Assessing the impact of swede midge on canola production in the Prairies and Ontario,” 2005-08, Rebecca Hallett, University of Guelph Grower...
