Verticillium update

Canola infected with Verticillium longisporum was discovered in Manitoba in 2014. This prompted follow up soil surveys by the CFIA in 2015, which did find V. longisporum in Alberta, British Columbia, Manitoba, Ontario, Quebec and Saskatchewan.
V. longisporum is related to V. dahliae, which causes wilt disease of potatoes and sunflowers, but V. longisporum symptoms in canola do not seem to cause yield loss at this time. 
This soil-borne fungal pathogen has been found in Brassica crops in parts of Europe and the U.S.
