Alberta Canola on Wednesday announced the Peace region has reported a case of clubroot in canola, in Big Lakes County, which surrounds much of Lesser Slave Lake in the region’s southeast. The disease has […] Read more
Clubroot climbs up into Peace region
High moisture levels could drive up canola diseases across province
Sclerotinia can reduce canola yields by up to 50 per cent — but a well-timed fungicide application can prevent some of those losses
