Manure-sourced P fertilizer increases crop safety

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...

Seed early to reduce swede midge damage

Swede midge on a canola flower
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...

Blackleg metabolites do not add risk to canola products for export

Key Practice: L. maculans, the fungal pathogen that causes blackleg in canola, can produce a mycotoxin called sirodesmin PL, but this study found none of it in Alberta canola samples. Project Title, Lead Researcher: “Evaluation of the toxicity of the secondary metabolites produced by Leptosphaeria maculans,” 2012-14, Xiujie (Susie) Li, Alberta Innovates — Technology Futures...

Biocontrol of canola cutworms

Insecticide application is the most common control option for cutworms in canola but it is very difficult to manage.
Key practice: The key to minimizing damage from cutworms is early detection through frequent field scouting. Proper identification of cutworm species can be important in the protection of beneficial insects and implementation of other biocontrols. Project title, Lead researcher: “Biocontrol of canola cutworms: Identification and attraction of parasitoids,” 2012-15, Barbara Sharanowski, University of Manitoba Grower organization...
