Manitoba Agriculture, Food and Rural Development (MAFRD) has identified Verticillium wilt (Verticillium longisporum) in canola (Brassica napus) in Manitoba. This is the first time this disease has been detected in Canada.

The disease was visually identified by the MAFRD Crop Diagnostic Centre on a canola sample submitted because patches of wilted canola were observed in a field. The pathogen culture was sent to the National Fungal Identification Service in Ottawa for molecular identification, which confirmed it as Verticillium longisporum. MAFRD is working with the Canadian Food Inspection Agency (CFIA) to implement biosecurity risk mitigation measures where this pest was detected. The CFIA will conduct further surveying in spring 2015 to determine the spread of the pathogen.
