Since the past few years, dimple rot has become one of the most serious diseases affecting Actinidia chinensis var. chinensis ‘Zesy002’ kiwifruit in Korea, leading to a low quality and subsequent losses of income. In the current study, the causal pathogen of side rot on ‘Zesy002’ kiwifruit was identified to be Botryosphaeria dothi- dea, a widespread pathogen that could penetrate the fruit directly without wounding. Diaporthe sp., another pathogen causing dimple rot, was isolated from...
