During this research, the effect of post-harvest treatments on reducing orange blight loss of Sutgolinella cultivar was studied. One of the aims of this study was to investigate the effect of plant essential oils and salicylic acid on growth of two species of fungi under in vitro conditions. This experiment was conducted as factorial in a completely randomized design with four replications. The experimental factors included antifungal (fennel, cumin, clove, eucalyptus, Ziryazia and salicylic acid), 700 and 1000 ?l fungi species for 400 and concentrations of 0 (Pencillium italicum and Pencillium digitatum) 2.5 and 4 mM for salicylic acid). The results showed that essential oils of Clove, Thymus, 1, Essential oil and 0 Shirazi and Cumin seeds at the same concentration of 1000 ?l / L had the most effect on reducing fungal growth, while Salicylic acid and Eucalyptus and Fennel essential oils had a negligible effect. Based on the results of this experiment, the essential oils and salicylic acid treatments were selected at concentrations of 1000 ?l / L and 4 mM, respectively, to determine the antifungal activity on inoculated fruits. The experiment was carried out in split plot based on completely randomized design with four types of distilled water (sterilized distilled water, acid, P. Italicum and P. digitatum). Treatments included salicylic fungi, essential oil of cumin, clove and thyme Shirazi) and the time of storage (Hifth, Twenty-Fourth, Thirty-Five, Thirty-Five, Eighth, Fourth, and Fifth). The results showed that the highest control of caries was on fungus inoculated fruits. Italicum was obtained in treatments of Zataria multiflora essential oils and clove and on fruits cultivated with digitatum fungus in treatments of essential oils of cumin and clove. These treatments caused a significant reduction in caries compared to P treatment
