Diversity key to blackleg resistance stewardship

Key practice: Diversity of cultivar resistance, crop rotation and fungicide usage can prevent both infection and breakdown of blackleg resistance. Project title, Lead researcher: “Blackleg Resistance Stewardship: Improving our management of host resistance,” 2010-14, Dilantha Fernando, University of Manitoba Grower organization funder: ACPC, MCGA, SaskCanola Leptosphaeria maculans, the fungal pathogen that causes blackleg in canola,...

Straight combining: environment and timeliness matter more than variety

Key practice: This study found that most hybrids could be straight combined successfully with minimal harvest losses when harvested in a timely manner under reasonably average environmental conditions. When making a seed decision, balance pod shatter resistance with other selection factors including yield potential, herbicide system, days to maturity and other agronomic factors. Project title,...

Protect canola from early insect feeding

Key practice: Use seed treatments and early in-crop treatments, if scouting deems them necessary, to protect young plants from flea beetles. Key research: Hallett, Rebecca, University of Guelph. “Assessing the Impact of Swede Midge on Canola Production in the Prairies & Ontario.” Canola Agronomic Research Program (CARP 2005-14). Olfert, Owen and Elliott, Bob, Agriculture and...

Follow insect thresholds

Key practice: Follow insect thresholds to manage input costs against potential yield response. Conserve and protect natural enemies and beneficial insects by using economic thresholds to determine the need and timing for insecticidal controls. Key research: Bracken, G.K. and Bucher, G.E. “An Estimate of the Relation Between Density of Bertha Armyworm and Yield Loss on...

Apply enough nitrogen

Key practice: Use soil tests, ideally taken at consistent locations (GPS helps), and base rate decisions on soil test recommendations. Key research: S.A. Brandt, Agriculture and Agri-Food Canada (AAFC), et al.“Seeding rate, fertilizer level and disease management effects on hybrid versus open pollinated canola (Brassica napus L.)” Canadian Journal of Plant Science, 2007.
