[Synopsis] The causal agents of postharvest berry rot during transportation, storage and marketing were investgated in the major grape producing areas of Xinjiang of China. Some filamentous phytopathogenic fungi were isolated and identified as Rhizopus stolonifer, Aspergillus niger, Penicillium spp., Guignardia bidwelli and Trichotecium roseum. R. stolonifer and A. niger were found to be most common fungi causing berry shutter and putrefaction dunring the normal temperature transportation and marketing process. Penicillium spp., B. einerea, Alternaria spp., Cladpsporum sp. and Sternphylium sp. also caused frequent dropping and putrefaction of berries during the low temperature transportation and storage. Furthermore, conditions for the outbreak of postharvest phytopathogenic fungi in the grape cultivars grown in Xinjiang were clarified in this study, providing an important clue for the control of these pathogens.
