Postharvest fungal diseases is one ofthe main reasons for extensive losses of mangoes. In northeast Brazil,Lasiodiplodia theobromae, Colletotrichum gloeosporioides andAlternaria alternata are the major causes of postharvest decay inmangoes. For exportation, a non-chemical postharvest treatment isessentiaI to ensure adequate contraI of postharvest pathologicaldeterioration. This study was undertaken to determine the effects ofhot water treatment to contraI postharvest decay of mango. Fruits ofmango cv. Tommy Atkins were artificially inoculated with L.theobromae or C. gloeosporioides. After 48 h of incubation, the fruitswere immersed in hot water at 53°C for L. theobromae and 50°C forC. gloeosporioides for times of upto 20 minutes. The treated fruitsthen were cooIed to room temperature and stored at lO±l°C for twoweeks. After storing, the fruits were maintained at 20±1°C andevaluated for decay controI. The results showed that hot watertreatment reduced postharvest decay 54.4% for L. theobromae and70.5% for C. gloeosporioides during 20 minutes.Program and Abstracts 304
