Factsheet of the month: January 2015 – Management of clubroot disease in crucifers

20147801509-page-0

Clubroot is a serious disease of crucifers. It is found in many countries across the world (see the Plantwise distribution map).  It is caused by the fungus Plasmodiophora brassicae, whose spores can live for many years in the soil. This makes the disease difficult to control once a field has been infected.
