| Abstract:
A fungus Penicillium cyclopium was isolated from ripe spoiled mango. Ripe fruits were more susceptible to infection by this mould as compared to unripe fruits. Various physical and chemical agents have been examined in an attempt to control spoilage by this organism. In-vitro studies revealed that bavistin exerted a greater inhibitory effect on the growth of Penicillium cyclopium as compared to aureofungin. Aureofungin (1–100 mg/l concentration) was unable to control natural infection in mangoes. A combination of 10 mg/l of bavistin and 100 mg/l aureofungin also failed to protect the mangoes against natural infection. However, bavistin at 100 mg/l concentration lowered the degree of spoilage considerably. Gamma radiation alone was not able to control spoilage effectively. Irradiation alongwith fungicide treatment succeeded in lowering the degree of infection, although not to the same extent as did the fungicide alone. Low temperature could also inhibit the growth of the mould. Artificially infected fruits, when stored between 10 and 20°C did not show any signs of spoilage. The study indicates that low temperature storage and treatment with fungicide can be exploited for the control of spoilage by Penicillium cyclopium. | |
