Inhibition effects of Zataria multiflora, Eucalyptus camaldulensis and Myrtus communis essential oil on mycelial growth of green mold of Orange

Abstract

In this study, <em>Penicillium digitatum</em>, the causes of green mould disease of orange fruits, were isolated from infected fruit in Bam city. Antifungal activity of three different plant essential oils <em>Eucalyptus camaldulensis, Zataria multiflora, Myrtus communis </em>at 50, 100, 150 and 200 ppm concentration, have been evaluated. MIC (minimum inhibitory concentration) and growth inhibition zone diameters analyzed as factorial experiment with 3 replications in a completely randomized design by MSTATc software. <em>Essential oil Zataria multiflora Due to having </em>Thymol and carvacrol as the main component has an important role in the antifungal properties.The essential oil of <em>Myrtus </em>has been shown the weakest antimicrobial effect.
