Verticillium wilt – Verticillium longisporum

Verticillium longisporum

The Canadian Food Inspection Agency (CFIA) has completed a national survey to determine the distribution of Verticillium longisporum in canola-growing regions of Canada.

Verticillium longisporum is a plant pathogen that can cause early plant death and decreased yield. It infects a broad range of crops, but the most severe impact is on canola. It was first detected in Canada in 2014, and since then, the CFIA, along with several industry and provincial partners, has conducted extensive surveying to determine the extent of its distribution nationally.

Verticillium longisporum has been detected in varying levels in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario and Quebec.

Landowners are encouraged to have a biosecurity management plan in place to prevent the introduction and minimize the spread of plant pests. Learn more about the National Voluntary Farm-Level Biosecurity Standard for the grains and oilseeds industry.
