Investigation effect of separate and combined essential oil of lavender) Lavandula angustifolia) and Savory (Satureja hortensis) on the Fusarium solani fungus

Most essential oil extraction from medicine plant have shown the properties of antimicrobial of parasites, bacteria, fungi and viruses. The fungus from genus of Fusarium is one of the prevalent crop disease that infect a wide range of crops. Fusarium solani is one of the species of this fungus genus that various crops are host for it. A lab experiment was conducted to investigate the effect of alone and in combination applied of essential oils of medicine plants, lavender) Lavandula angustifolia) and Savory (Satureja hortensis) on control growth of the fungus. The experiment was completely randomized factorial design with two factors, different essential oils (essential oil of lavender and Savory) and various concentration of essential oils (0, 50, 75 and 100 ppm). Treatments were replicated in five. Result showed that essential oil extracted from Savory is more effective in inhibitory growth of F. solani than essential oil of lavender. Using both essential oil and applied at the various levels of their concentrations did not completely inhibit growth of the fungus F. solani. But using mixed essential oil of both plants and at the highest concentration level (100 ppm) completely inhibited the growth of F. Solani.
