Effect of essential oils in control of plant diseases.
In this study, antifungal activity of some essential oils, extracted from Syzygium aromoticum, Foeniculum vulgare, Cuminum cyminum and Mentha piperita were investigated against grey mould of apple. The essential oils of S. aromaticum and F. vulgare showed considerable antifungal activities on PDA medium against Botrytis cinerea. Results indicated that the increasing of dosage of the essential oils caused to the more antifungal activity against B. cinerea in vitro condition. After 10 days, results showed that the essential oil of F. vulgare in both of the concentrations (750 and 1000 microL/L) was more effective than the essential oil of S. aromaticum against grey mould of apple and decrease the disease up to 15.5% in comparison with the check treatment (100%). After 20 days, biocontrol potential of the essential oils of S. aromaticum and F. vulgare at 1000 microL/L were more effective than the other treatments and the percentage of disease was evaluated 41.6% and 50.8%, respectively, in comparison with the check treatment (100%).
