Hot water treatment for disease control and extension of shelf life of Kesar mango (Mangifera indica L.) fruits.
The present investigation was undertaken to study the effect of post harvest hot water treatment for disease control and extension of shelf life of Kesar mango fruits grown under arid zone.For this purpose, the mango fruits were harvested at proper stage of maturity and given hot water treatments at 52 °C for 10 minutes either alone or in combination with fungicidal dips viz., Bavistin (0.1%) and Captan (0.2%).The mango fruits were then packed in corrugated fibre board box and then stored in two storage environments viz., at room temperature (28.12 to 36.18 degree centrigrade temperature and 46.18 to 71.25% RH) and in zero energy cool chamber (21.47 to 27.10 °C temperature and 91 to 95%).It was observed that hot water treatment combined with Bavistin (0.1%) was found to be the best in controlling the incidence of anthracnose and stem-end rot.It was also found that shelf life of mango fruits could be extended for more than 28 days when given hot water treatment coupled with fungicides and stored in cool chamber.On the contrary, the shelf life of fruits was found to be 21 days when given same set of treatments and hardly 17 days when untreated and stored at room temperature.It was also observed that hot water treatment coupled with fungicide to mango fruits recorded lower physiological loss in weight and high organoliptic score when stored in cool chamber as compared to room temperature storage.The untreated (control) fruits were found to have infected with Colletotrichum goeosporioides and Diploidia natalensis.
