Lac Ste Anne County Annual Clubroot Inspection
Clubroot of Canola was first discovered in Edmonton in 2007, and has rapidly spread throughout the province of Alberta at an unprecedented rate. This pathogen spreads through the movement of soil. This is mostly done via farm equipment, but many other methods such as ATVs, shoes, and wildlife can spread the pathogen as well.
The pathogen causing clubroot, Plasmodiophora brassicae, produces resting spores that are activated by the presence of host plants’ roots. These resting spores become zoospores, which infect the roots; this causes ‘clubbing’ or galls on the roots. When the plant dies, the galls decay, releasing the spores into the soil where they await another host plant to re-start the lifecycle.
Lac Ste. Anne County performs an annual inspection of all canola fields within the county, as per Policy 408 – Control of Clubroot Disease, found here. This is done to monitor the pathogen’s movement and reduce the spread throughout our County.
We offer a map that shows where the clubroot-susceptible crop restrictions are, for producers to make their own informed cropping decisions and reduce their risk. A copy is available for viewing at the County office.
We will be having another clubroot information session on Tuesday, November 20, 2018. We will be covering topics including: pathogen lifecycle, management strategies, and resistance breakdown. More details will be released later in the year.
