What Causes Clubroot in Canola?

Clubroot in canola is caused by Plasmodiophora brassicae, a parasite that infects the roots of host plants and produces club-shaped galls that restrict the flow of water and nutrients. Plasmodiophora brassicae is an obligate parasite, meaning it cannot survive without a living host.

What is a Fusarium DNA Test?

A fusarium DNA test, otherwise known as a molecular diagnostic, is a test that detects the presence of Fusarium graminearum through DNA.

Why Do a DNA Test?

F. graminearum causes fusarium head blight (FHB) in cereal crops, reducing yields and producing a mycotoxin that prevents or limits grain sales into food and feed markets.

While fungicide treatments can limit the extent of infection, they cannot prevent FHB from happening, and there are no effective means of rehabilitating fields once infected.
