Black-spot symptoms, caused by Alternaria alternata, develop in 'Triumph' persimmon fruit during prolonged storage at -1 degree C. Preharvest dip treatment in the organic chlorine compound Troclosene sodium extended the storage life of the fruit by delaying development of black-spot disease (BSD). Troclosene sodium was more stable and efficient for the control of A. alternata than calcium hypochlorite. At 500 microgram ml(-1) Troclosene sodium significantly reduced the development of BSD in persimmon fruit sampled in 15 orchards in different growing regions of Israel. Following commercial dipping and storage at -1 degree C, the percentage of marketable fruit after 4 months of storage was 15-40% higher than in untreated fruit. Present results suggest that the BSD can be controlled by a simple dip treatment with chlorine disinfectant.
