Postharvest diseases of domestic and imported fruits and vegetables were surveyed once a week at Kyoto municipal central market and at small stores in Osaka and Kobe cities, Japan from May to Nov. 1990. The fungi were isolated on potato-dextrose agar medium, and the spores formed by the isolates were compared with illustrations and descriptions in books on classification. Of the 63 isolates, most had already been found on citrus fruit, stone fruits, pome fruits, berries, root vegetables and fruit vegetables. New findings were of Geotrichum sp. on Japanese apricot, Pestalotia sp. on plum, Aspergillus niger on apple, Monilia fructigena on Chinese quince, Trichothecium roseum on grape, Geotrichum candidum on carrot, Penicillium sp. on Chinese yam, Alternaria alternata on Japanese Capsicum, A. alternata, Fusarium sp. and Penicillium sp. on malabar spinach, Penicillium spp. on spinach, A. alternata, Cladosporium sp., Penicillium italicum and Penicillium digitatum on maize and Alternaria sp. and Fusarium sp. on globe artichoke. Fruit and leaf vegetables often had Penicillium spp. (12 isolates), Fusarium spp. (12 isolates) and Alternaria spp. (11 isolates), but Monilia spp., Rhizopus spp. and Aspergillus spp. were only recognized on fruits and Cladosporium spp. and Geotrichum spp. were found on both fruit and root vegetables. Some isolates of the former 3 genera have not yet been identified to the level of species. It is concluded that these fungi are important organisms in the study of postharvest diseases, as they probably produce mycotoxins that cause serious problems in animal and human health.
