The activities of extracts from Orostachys fimbriatus, Euphoribia helioscopia and a prescription of some Chinese traditional Herbs against three Fusarium and two Erwinia were tested. The results indicated that extracts from Orostachys fimbriatus exhibited strong antifungal and antibacterial activities.The antifungal activities of Orostachys fimbriatus was from 91.39% to 100% when 5mL extracts was added to 50mL media.While inhibition rates of the other two extracts against three Fusarium were less than the Orostachys fimbriatus. In addition, inhibition rates soon declined when the volume of added extracts was reduced to 2mL, 1mL and 0.5mL.On the other hand, inhibiting effects of extracts against Erwinia chrysanthemi pv. chrysanthemi and Erwinia carotovora pv. carotovora have the same trend as their antifungal activities.
