YU Dong-po et al(Henan Agriculture University,Zhengzhou,Henan 45002)  
[Objective]The aim of the research was to develop the perfect botanical fungicide.[Method] In lab test,with Botrytis cinerea and Alternaria solani as tested epiphyte strains,the antifungal activities of alcohol extracts from 21 Chinese medicinal herbs were tested through plate growth rate method.[Result] In the primary screening test with the extracts at 0.02 g/ml,7 extracts from the plants such as Syzygium aromaticum and Pharbitis nil expressed significant inhibitory effects against the mycelium growth of A.solani and B.cinerea, with the inhibitory effect over 70% and 50% resp.In the secondary screening test with the extracts at 0.01 g/ml,the inhibitory rate of 4 extracts from the plants of S.aromaticum,Asarum heterotropoides,Magnolia liliflora and Sophora flavesceus against A.solani were 100%,69.67 %,62.52% and 62.21%,being quite to that of carbendazim;the inhibitory rate of 5 extracts from the plants of S.aromaticum,Coptis chinensis,S.flavesceus,Alpinia officinarum and A.heterotropoides against B.cinerea were 100%,72.60%,67.30%,63.90%and 54.30%,being obviously higher than that of carbendazim(6.90%).[Conclusion] The inhibitory effects of S.aromaticum,S.flavesceus and A.heterotropoides were obvious against the mycelium growth of two epiphytes.
