Abstract: |
In this study, the antifungal effects of four species of plant essential oils, including Thymus vulgaris, Eucalyptus camaldulensis, Lavandula angustifolia and Cuminum cyminum, were studied on mycelial growth inhibition of F. oxysporum and F. culmorum isolates. The effect of essential oils was carried out in a factorial experiment in a completely randomized design with four concentrations for each essence and three replicates in 25 °C on PDA medium. The results showed that the essential oils of these plants has a significant effect on inhibition of the mentioned pathogenic isolates fungal mycelial growth. The required concentrations for the maximum mycelial growth inhibition of F. oxysporum isolate in 250 ppm for essential oils Cumin, Eucalyptus, Thyme and Lavender were 100, 96, 93 and 89 percent, and for F. culmorum isolates were 99, 96, 92 and 77, respectively. The minimum inhibitory concentrations of the cumin, Eucalyptus, thyme and lavender on F. oxysporum in 50 ppm were 48.8, 29.4, 44 and 38 respectively and for F. culmorum these concentrations were 38.8, 29.4, 44 and 18 percent respectively. The highest and lowest mycelial inhibitory growth was showed by cumin essence in 250 ppm and lavender and eucalyptus essences in 50 ppm, respectively. In all four essential oils, the growth of the fungi decreased by increasing the essential oil concentration. Regarding the antifungal and inhibitory effects of the essential oils of the plants and their low risk for humans and the environment, it seems that plant essence can be used to control plant pathogenic fungi or at least as substitution for the production of new fungicides.
