Diversity key to blackleg resistance stewardship

Science Edition 2015—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,...

Ensure all crop inputs are working together

Science Edition 2014—Key practice: Recommended fertilizer rates and seeding rates that provide for a competitive stand will make canola more resilient against weeds, insect damage and disease. Key research: Brandt, S.A., 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.).” Effective pest...

Genetics will reduce harvest losses

A recent study by Andrea Cavalieri with the University of Manitoba found that pod shatter is primarily impacted by genotype, while environment is the dominant driver for pod drop.

Science Edition 2014—Key practice: Canola varieties with pod shatter tolerance have arrived. Pod shatter tolerance adds more flexibility for harvest timing, allowing crops to stand longer with fewer losses. Key research: Cavalieri, A., University of Manitoba, et al. “Pod Drop and Pod Shatter Are Not Closely Related in Canola.” Crop Science (2014). Gan, Y., Agriculture and Agri-Food...

Target seven to 10 plants per square foot

Science Edition 2014—Key practice: Target a population of at least seven plants per square foot to maintain yield potential for canola. This target will allow for some plant mortality due to post- seeding stresses without dropping below the minimum five plants per square foot required for canola yield potential. Key research: Leeson, Julia, Agriculture and Agri-Food Canada...

Rotate crops for blackleg and clubroot management

Science Edition 2014—Key practice: Increasing the number of years between canola crops in the rotation reduces incidence and severity of blackleg and clubroot in fields.
