Clubroot in Brassica
Abstract: Clubroot is a very serious disease of Brassicaceae species worldwide, affecting especially B. oleracea (cabbage), B. napus (oilseed rape) and B. rapa (turnip). Plants with clubroot show wilting, stunting, yellowing and premature senescence. In some cases, the field can be destroyed entirely. This paper summarises some of the research that is being undertaken on this disease in Europe.
