While evaluating plants at two locations in North Central SK, Cargill plant scientists observed nodules on certain canola plants. There were no above ground symptoms, and the nodules were observed only because the plants were pulled from the ground for whole-plant observation.
Plant root tissue and soil samples from this site were sent by Cargill to an independent lab for analysis. An analysis of plant tissue samples, using a DNA test, were positive for the presence of the clubroot pathogen.
In accordance with the Saskatchewan Pest Control Act, Cargill has restricted access to the location where the affected plants were found.
Lorin DeBonte, assistant vice president, Cargill Specialty Canola, said: “Upon discovering the presence of clubroot, we notified grain growers and owners of lands around the disease observation nurseries and provided them with the guidance and resources they required to manage the issue in a timely and cautious manner.”
In an abundance of caution, Cargill is working with the Ministry of Agriculture, the Canola Council of Canada and the impacted grain growers and landowners to manage the confirmed sites in accordance with the Saskatchewan clubroot management plan, the company said.
