Moist conditions in 2016 may have helped to fuel an aggressive advancement of clubroot pathotypes, many of which can quickly overcome current clubroot resistance traits, warns the Alberta Canola Producers Commission.

Since new data indicates some forms of clubroot resistance are no longer functioning well against new clubroot pathotypes in some of the heavily infested fields, the Alberta Canola Producers Commission encourages growers to consider a comprehensive management plan that includes crop rotation, sanitation and the use of clubroot resistance varieties.
