Effects of Sophera flavescens extracts were studied on spore germination and mycelium growth of eggplant Verlicilium dahliae. Extracts of S. flavescens inhibited the Verticillium dahliae allelopathically, owing to its active substances flavonoids and alkaloids. At the same concentration, the flavonoids are less inhibitory. Increase in S. flavescens extracts concentration decreased the mycelium dry weight and the activities of extracellular enzymes. The inhibitory effects were significant compared to the control. The allelopathic inhibition of Verticillium dahliae by S. flavescens extracts can be attributed to decreased mycelium growth, lower dry weight and less activity of extracellular enzymes.
