Canadian Flag Detection of Verticillium wilt of canola (Verticillium longisporum) in Manitoba

In November 2014, the Canadian Food Inspection Agency (CFIA) confirmed the presence of Verticillium longisporum (Verticillium wilt) in canola at a single location in Manitoba. This detection is limited to a trial plot which is not being used for commercial seed production. Prior to this detection, V. longisporum had not been reported from Canada.

V. longisporum is a plant pathogen that can cause early senescence and decreased yield. It can infect a broad range of crops, primarily within the Brassicaceae, but the most severe impact is on canola.

Consistent with the International Plant Protection Convention (IPPC) and its international standards for phytosanitary measures (ISPMs), the CFIA has implemented provisional measures to contain the pest while the regulatory status of V. longisporum is being determined. Over the next few months, the CFIA will continue sampling, survey and surveillance activities in order to confirm if this is an isolated occurrence (i.e., “transient” as per ISPM 8: Determination of pest status in an area) or if there is any further distribution of this pest.
