Glucosinolates in canola residue could influence nitrogen release

Science Edition: Fertility Management
Science Edition 2019—KEY RESULT: This study confirms there is significant potential for canola residues to enhance N2O emissions relative to those associated with wheat, flax and pea residues. This potential appears to be associated with the release and subsequent transformation of glucosinolates into a variety of bioactive compounds during crop residue decomposition. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Identifying...

Tips for a more integrated approach to flea beetle control

Science Edition: Integrated Pest Management
Science Edition 2019—KEY RESULT: This study validated the nominal economic threshold of 25 per cent defoliation. It also determined significant associations between landscape structure and flea beetle abundance, weather and flea beetle abundance, and plant density and flea beetle damage. As well, two flea beetle predators were confirmed. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Integrated approaches for flea beetle...

Pollinators increase yield and mitigate drought impacts

Science Edition: Integrated Pest Management
Science Edition 2019—KEY RESULT: Pollinators increased canola yield by promoting earlier flowering and reducing loss associated with drought. However, pollinators were unable to compensate for suboptimal seeding rate or low nitrogen fertility. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Getting more bang for your buzz: Does pollination compensate for canola yield lost under sub-optimal soil moisture, nitrogen fertilization and/or seeding...

New tool forecasts Sclerotinia risk

Science Edition: Integrated Pest Management
Science Edition 2019—KEY RESULT: The canola growth stage prediction model and sclerotinia stem rot risk index deployed on www.canoladst.ca are useful tools for managing the disease. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Operational models to forecast canola growth stage, Sclerotinia risk, and yield in Western Canada,” Rishi Burlakoti, Agriculture and Agri-Food Canada FUNDING: Growing Forward 2 The major objectives...

Tests to improve Sclerotinia sclerotiorum control

Science Edition: Integrated Pest Management
Science Edition 2019—KEY RESULT: Heads Up, a resistance activator applied to seed, was found to enhance resistance against Sclerotinia sclerotiorum causing white mould in dry bean, but showed no benefit for canola. Adding a micronutrient to a foliar fungicide improved control of S. sclerotiorum for two of the six fungicides tested. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Improving Sclerotinia...
