Clubroot (Plasmodiophora brassicae) is an important disease of organic brassica crops. Organic soil amendments were added at realistic rates and times to infested organic soil in pot trials in order to evaluate their effect on the disease. Both chitin and straw amendments reduced disease incidence compared to other amendments but straw also reduced plant vigour.
