摘  要:
The crude extracts of Sophora flavescens Ait and flavone and alkaloid were bioassayed by using growth rate and pendant-drop methods for antifungal activity of Capsicum blight at different concentrations.The results showed that crude extracts performed significant antifungal activity.The inhibition rate was 94.48% on mycelium growth and the inhibition rate on the spore germination was 89.01% as the concentration was 40 g/L.And the antifungal activity of flavone were more active than alkaloid.
