Abstract
Rhizopus rot of mango, atemoya and white sapote fruits occurred on Chichijima in Ogasawara (Bonin) Islands in 2012 and 2013. Fungi isolated from the disease plants were identified as Rhizopus stolonifer var. stolonifer. Inoculation tests confirmed that this fungus was the causal agent of the diseases. This is the first report of these diseases in Japan.
