In order to find the plant extracts with antifungal activity, 18 plant species were screened. In this study, distilled water, methanol, chloroform, aceton and ethanol were employed to obtain crude extract from plant samples. The extracts were tested against sugar beet root rot agents, Rhizoctonia solani and Phytophthora drechsleri. The inhibitory effect of different extracts was investigated by paper disc method. The most effective antifungal compounds belonged to Carum copticum, Zataria multiflora and Pinus halepensis extracts, so that they showed high inhibitory activity in 1 mg/paper disc. The results of this research revealed the high potential of using natural plant extracts for controlling of plant pathogens.
