Comparison of volatile and contact effect of essential oils on growth of Fusarium graminearum

Cilj ovog istraživanja bio je utvrditi kontaktni i volatilni utjecaj šest eteričnih ulja na porast micelija gljive Fusarium gramineaerum. Korištena su eterična ulja timijana, anisa, limuna, bora, ružmarina i naranče. Ulja su primijenjena u količinama 10, 30 i 50 μL. Porast micelija mjeren je nakon 48, 120 i 168 sati. Najjači antifungalni učinak imalo je eterično ulje timijana i pri kontaktnoj i pri volatilnoj primjeni. Eterična ulja limuna i anisa su imala značajno bolje antifungalno djelovanje pri kontaktnoj primjeni u odnosu na volatilnu primjenu. Ulja naranče i bora bolje su djelovala pri volatilnoj primjeni.The aim of this study was to determine volatile and contact effect of six essential oils on the growth of mycelium of the fungus Fusarium graminearum. Essential oils of thyme, anise, lemon, pine, rosemary and orange were used. The oils were applied in three quanttities: 10, 30 and 50 μL. Mycelial growth was measured after 48, 120 and 168 hours. Essential oil of thyme had the strongest antifungal effect, both in contact and volatile application. Essential oils of lemon and anise had better antifungal effect in contact application than in volatile. Orange and pine essential oils had better antifungal effect in volatile application
