Research on Antifungal Activities of Extracts from 13 Plants on Phytopathogenic Fungi

The antifungal activities of acetone crude extracts from 13medicinal plants in Yunnan Simao on Rhizoctonia solani,Alternaria solani,Fusarium solani,and Colletotrichum musae were determined by grow rate methods.The results indicated that acetone extracts with different concentration(0.1,0.01g/mL and 0.005g/mL)from the 13medicinal plants showed inhibition activities on the mycelia growth of 4sampled phytopathogenic fungi,and the inhibition rate were from 1.0%to 90.2%.The inhibition rates of Glochidion puberum,Euodia leptaand Polygonumh ydropiper on 4fungi were from 11.7% to 90.2%,so the G.puberum,E.lepta and P.hydropiper had values for further research and development.
