Popis: Increasingly global there is an interest to develop a new method by replacing fungicides in packaging fresh fruit by using environment-friendly bio-pesti-cides, such as use of botanicals or biological control. Five ethanol extracts (concentrations 500 - 5000 ppm) of Cerbera odollam L. (Pong-pong), Capsicum frutescence L. (Chili), Azadirachta indica L. (Neem), Cymbopogon nardus L. (Lemon grass), Zingiber officinale L. (Ginger), were tested for their anti-fungal activity for citrus green mold, black and brown rot, compared with the control fungicide (Guazatine). Efficacy of the selected plant extract in cooperated with biodegradable materials wrappers (Polylactic acid, Pectin and Newspaper) was determined during storage at room temperature (±25℃) to control fruit-pathogen decay under modified atmosphere packaging (MAP) to increase shelf life and improve the fruit quality. Crude extracts from pong-pong and chili showed fungal inhibition zone at 3000 ppm (c.100%), and increased shelf life and decreased weigh loss for fruits wrapped and stored at room temperature compared with untreated fruit.
