Proceeding of A Symposium on Postharvest Handling and Marketing of Horticultural Crops
Ten kinds of postharvest diseases were occurred severe on the citrus cultivars when survey was done in the foreign country. They were green mold, blue mold, anthracnose, diplodia stem- end rot, phomopsis stem-end rot, fusarium rot, alternaria rot, brown rot, gray mold and cottony rot. Five kinds of postharvest diseases were occurred frequently in Taiwan, when surveyed continuously within recently three years. They are green mold, blue mold, anthracnose, fusarium rot and alternaria rot. The disease caused by Botryosphaeria sp. also occurred commonly. The gray mold and sclerotinia are found scarcely in Taiwan. The variety sweet orange( Citrus sinensis Osb.) was the most severe when different varieties were store and showed different degree of sensitivity to postharvest diseases. Both the cultural practice and methods of harvesting and transporting could influence the occurrence of postharvest diseases. The injury produced during the harvesting and handling period could induce the severity of postharvest diseases if the fruit were harvested in the raining days. The major reason is because of the high humidity for disease to development and the infection occurs commonly through injuries inflicted during harvesting and handling. The dipping method showed more effective than other methods when fungicides were used and high residue problem was remained. Another three factors could influence the occurrence of postharvest disease significantly. They were the sanitary of packinghouse, number of diseased fruits and cleaning of the packing material. The strategy for controlling postharvest disease followed step by step are good cultural practice, avoiding injury formation during harvesting, treatment of chemicals after postharvesting, and sanitary of packinghouse and packing material.
