Abstract : Two experiments were conducted to investigate the effects of soyabean oil in the control of postharvest anthracnose (Colletotrichum gloeosporioides) infecting mango cv. Palmer fruits. Mango fruits were harvested at the third and fourth ripening stages and were subjected to the following treatments: immersion for 5 minutes in water (control), benomyl at 100 g/100 litre water, thiabendazole at 240 g/100 litre water at 22, 40 or 45°C; and in different concentrations of soyabean oil alone or in mixture with benomyl, thiabendazole and ethanolic extract of sucupira fruit (Pterodon pubescens). After treatment, fruits were maintained at room temperature 27±1°C and 72-85% relative humidity, and at 17°C and 85-100% relative humidity. Evaluation of control efficacy was at 15 and 30 days after treatment. The percentage of the fruit area with lesions; the percentage of ripe, half-ripe and unripe fruits; Brix percentage; and texture, were investigated. Soyabean oil applied alone of with benomyl or thiabendazole at 22 or 40°C increased the shelf life of mango and efficiently controlled anthracnose.
