Study aims to mitigate risk of Verticillium stripe and blackleg in Western Canada

February 8, 2023  By Top Crop Manager


To help with 2023 disease studies, Alberta, Saskatchewan and Manitoba growers are now able to volunteer their fields for monitoring of Verticillium stripe, as it has been on the rise, particularly in the eastern Prairies.

The Canola Council of Canada grower survey in late 2022 asked growers to list the pests that represent the greatest economic risk to their canola production. Blackleg and Verticillium stripe both rose up the list since the 2020 survey. Notably, 24 per cent of Manitoba farmers included verticillium stripe in the 2022 survey, compared to less than 10 per cent in 2020.

Research shows an interaction between the blackleg and Verticillium stripe pathogens, and both can be present in the same plant. But these diseases are distinctly different and accurate identification helps with management.
