| Abstract: | The fungistasis of six herbal extracts were tested in vitro with C.capsici and B.cinerea by growth rate method to provide references for disease control of green vegetable.The results showed that the extracts from Scutellaria against two pathogenic fungi got the highest inhibitory activities in six herbs,the EC50 values were minimum,8.56 mL/L and 8.65 mL/L respectively.The extracts of Rheum palmatum had the lowest inhibitory activities,the EC50 values were 104.32 and 269.43 respectively.Compared with the extracts of Scutellaria,the extracts of Sophora flavescens,Lonicera japonica,isatis root and Psoralea corylifolia had medium inhibitory activities. |
