Evaluation of positive and negative effects of essential oil samples of Ferula gummosa Boiss. on two plant phytopathogenic fungi

In this research antifungal activities of the essential oils of Ferula gummosa Boiss.from three localities (Kashan, Ilam and Semnan) against two plant phytopathogenic fungi (B. cinereaandRhizopus stolonifer) were evaluated. The antifungal activities of essential oils against B. cinereashowed that the essential oil of all samples were effective against the growth of this fungus. As the control with 0 ppm concentration of the essential oil showed the highest and the 1200 ppm the lowest growth of B. cinerea. In contrast, the effect of the essential oils on the growth of Rhizopus stolonifer revealed a relatively positive effect on the higher concentrations. Our results showed that the increasing amount of the essential oils of F. gummosa can conclude different effects on different fungi.
