Assessing Efficacy of Some Egyptian Medicinal Plants Extract against Postharvest Fungi cause Spoilage of Fruits.

[摘要] Considerable losses of fruits during handling, packaging, transportation, and storage. Five infectedfruits were collected [apple, grapes, mandarin, peach, and plums] from the local market of DamiettaGovernorate, Egypt for surveying the fungal pathogens on these fruits. Ten fungal species were isolated andidentified, among them, Alternaria alternata and Fusarium oxysporum exhibited the most dominant fungalspecies were isolated from apples and peaches, respectively. Results indicated that the aqueous extracts ofthree medicinal plants [Eucalyptus citriodora ĽHér, Inula crithmoides L., Launaea nudicaulis [L.] collected fromthe area around were tested against the two dominant fungi at four concentrations [0.0, 0.25, 0.5, 1%; w/v].The greater relative inhibition of fungal growth was recorded at the concentration of 1% of both plants, but theextract of Eucalyptus citriodora was more effective against tested fungi than that of other plants. So, the use ofEucalyptus citriodora extracts as potential antifungal preservatives for fruits against fungal spoilage instead ofsynthetic fungicides because they are available, safe, inexpensive, and ecofriendly.
