Bio-control of Post-harvest Fungi of Some Fruits

The present study aimed to bio-control the loss of fruits after harvest due to fungal infection . A trail was carried out to limit the use of chemical synthetic fungicides which impose serious health problems on human severe pollution of the environment and even the decrease in the national economy.Ten different spoiled fruits showing fungal infection were collected from different markets from Damietta Governorate were namely: apple banana grapes guajava mandarin mango orange plum pomegranate and strawberry. Ten pathogenic fungal species were isolated and identified viz; Aspergillus niger A. flavus A. ochraceous A. nidulans Penicillium expansum P. Chrysogenum Alternaria alternata Fusarium oxysporum Rhizopus stolonifer and Cladosporium herbarum. By determination of the percentage of fungal occurance Alternaria alternata and Fusarium oxysporum were the most prevelant species and selected for the further study.
