How to protect clubroot resistance

November 13, 2015

KEY PRACTICE: Use an integrated approach to clubroot management that includes a resistant cultivar, proper rotations and sanitation of seed and equipment.

PROJECT TITLE, LEAD RESEARCHER: “Effects of clubroot resistant canola lines on soils infested by Plasmodiophora brassicae,” 2010-14, Sheau-Fang Hwang, Alberta Agriculture and Rural Development (AARD) and Stephen Strelkov, University of Alberta

GROWER ORGANIZATION FUNDER: Alberta Canola, MCGA, SaskCanola


Clubroot is a soil-borne disease caused by Plasmodiophora brassicae. It’s an emerging threat to canola production. Results of this study show that effective clubroot management relies on cultivar resistance in combination with management practices that reduce viable resting spore populations.

Originally identified near Edmonton in 2003, clubroot has since spread to nearly 2,000 fields across Alberta. It has been detected in Saskatchewan and has been confirmed through soil testing in several municipalities in Manitoba. Yield losses in severely diseased fields have ranged from 30 to 100 percent.
