Abstract :Investigations on alternative control methods to chemicals including usage of plant extract for plant fungal disease take important place in current researches. Plant extracts are generally deemed to be less hazardous than synthetic compounds and could be alternative to antifungal treatments. In this study, the purpose was screening of some plant extracts against Fusarium culmorum causing foot and root rot on different small-grain cereals, in particular wheat and barley. In total 6 plant species including levander (Lavandula angustifolia), common mullein (Verbascum thapsus), common sorrel (Rumex acetosa), wood avens (Geum urbanum), poison hemlock (Conium maculatum), henbane (Hyoscyamus niger) consisted the materials in the study. The antifungal effects of three different concentrations (20%, 40%, and 80%) of each extracted plant, obtained from dried plant parts in methanol, were evaluated on growth of F. culmorum by dual test technic on PDA (Potato Dextrose Agar). The maximum in vitro inhibitory efficiencies were obtained from common mullein (Verbascum thapsus) at concentrations of 80% and 40% with the ratios of 46.66% and 33.33% respectively, while no repressive activity exhibited by other plant extracts on pathogen growth on PDA.
