Update regarding COVID-19
The Alliance is committed to ensuring the health and safety of staff, animals, researchers and the community. We are following guidance set out by the University of Guelph’s Office of Research with respect to biosecurity [4] and research activities during COVID-19. Please keep in mind the status of projects may change as the response to this pandemic evolves.

| 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. |
