Last year, verticillium stripe was found in 40 percent of canola fields in Manitoba.
That’s a huge number, considering the first detected case in Canada was found in 2014 at a farm south of Winnipeg.
The fungal disease has also moved into eastern Saskatchewan and is becoming a common problem in that region.
Verticillium is obviously spreading at a rapid rate, and a former Canola Council of Canada agronomist believes that straight cutting of canola is partly responsible.
