Evaluation of antifungal effect and non-growth diameter, of Persian oak’s Jaft extract on Penicillium digitatum and Penicillium italicum molds (indicator of mold spoilage after citrus fruits harvest)
The usage of plant extraction such as tannins, flavonoids & et. as an alternative to fungicidal effects. The aim of this study was to evaluate of the antifungal effect of Iranian oak Jaft extract after extraction by different methods on Penicillium italicum and (Penicillium digitatum as an indicator of citrus fruit mold spoilage. molds were expossered by different concentrations of oak Jaft extract. The investigated factors including minimum inhibitory concentration (MIC) (mg/ml), minimum lethal concentration (MFC) (mg/ml) and non-growth diameter (mm) were determined by the methods of tube dilution, surface culture and diffusion in agar well (WD). The results showed that different concentrations of aqueous extract had significantly effect (p<0.05) on the non-growth diameter of molds. The antifungal effect was significantly (p<0.05)increased in concentrations of 40 and 80 mg/ml aqueous extract. In this research, Fludioxionil 25% poison as a control group showed a significant difference(p<0.05) in molds growth. In general, the extract of Iranian oak Jaft can be used to control the fungal spoilage of citrus fruits.
