The effectiveness of hot water immersion as a disease control on ‘Keitt’ mangoes was carried out in this study. In this experiment individual fruits were treated with hot water at varied temperature and times and evaluated over a 21 day storage period, at room temperatures of 25-31oC with a relative humidity of 70-80%. The internal qualities such as pH, TTA and TSS of the fruits were not affected by the treatment. However, most fruits were in best condition for eating with minimal disease incidence and ready-to-eat firmness when stored for about 14days. Hot water treatment at 52oC for 5 minutes could keep the fruits wholesome and free from anthracnose for the 21 days storage period.
