Clostridium Soft Rot (Clostridium spp.)

Pathogen. Clostridium bacteria are present in most soils.

Disease development. The bacteria probably infects tubers at harvest. The disease is favoured by the presence of a film of water on the tuber surface, which decreases the oxygen concentration in the internal tissues. Usually, in tubers infected with clostridium soft rot, the decay is caused by more than one bacterial species.
