Several species of fungi, belonging to the genera Botrytis, Cladosporium, Alternaria, Pestalotiopsis, Fusarium, Penicillium, Stemphylium, Rhizopus and Aspergillus, were isolated from rotten grapes harvested from fields and markets in different localities in Japan. Inoculation of fresh grapes with these isolates indicated that all the isolates were pathogenic to injured grape berries. All, except for Cladosporium, Fusarium and Aspergillus spp., were capable of rotting uninjured fruits. Two species of Pestalotiopsis, frequently isolated from decayed fruits of different cultivars, were characterized morphologically and identified as P. menezesiana and P. uvicola. Upon inoculation, these 2 species caused the fruit rot observed in fields and markets. They were isolated not only from diseased and healthy looking fruits, but also from the air in grape orchards. It is concluded that latent infection or conidial attachment to the berries in fields could initiate postharvest disease of grape. This is the
first description of Pestalotiopsis spp. as the causal agent of a postharvest disease of grape.
