Research summary
Objective To determine the distribution and pathotypes (subspecies) of clubroot in cabbage and canola fields across Ontario. Subsequently, cabbage and canola cultivars in Ontario will be screened for resistance to specific pathotypes; best management practices to reduce clubroot potency will be evaluated; and effective treatment methods for small infestations will be developed. 
Benefit to Agri-food Clubroot is a devastating disease that has affected Ontario cabbage and canola crops for decades. It can result in up to 100% yield losses. This research will provide alternative management practices and treatment options for this persistent disease.
