Pedicels near the stem end of mango fruits (1 cm from stem end) were infected with many microorganisms. Within this group of microorganisms, Lasiodiplodia theobromae, Dothiorella dominicana and Phomopsis mangiferae were the cause of stem-end rot. Mango fruits harvested with pedicels and detached before ripening at 25 deg. C had less L. theobromae infection than the fruits harvested without pedicel and desapped on the ground in the orchard. This phenomenon was not found in the case of D. dominicana and Phomopsis mangiferae. Storage temperature (13 deg. C, 25 deg. C) had no effect on the incidence of Dothiorella and Lasiodiplodia rot but Phomopsis rot incidence was increased as the temperature was decreased. Surface disinfection with 1 percent sodium hypochlorite before storage also had no effect on the stem-end rot incidence.
