Canola Verticillium Wilt

Verticillium Wilt is a common disease found predominately in Northern Europe, but in 2014, it was found in Manitoba. This is the first time the disease has been detected in Canada. The plant pathogen is a soil-borne, fungal disease that initially infects the root system at the seedling stage. The results of the infection are early death of the plant and reduced crop yield in canola.
