Abstract:Seven kinds of herbs were screened on the three plant pathogen Venturia inaequalis,Fusarium oxysporum f.sp. lycopeersici,Colletotrichum gloeosporioides.The results showed that the extract of Cnidium monnieri and Polygonum cuspidatum had strong antifungal activity on the Colletotrichum gloeosporioides and Fusarium oxysporum f.sp.lycopeersici,the EC 50 of which were 0.8046 g/L and 0.3877 g/L respectively on the Colletotrichum gloeosporioides in 72 h,but 0.8817 g/L and 0.44693 g/L on the Fusarium oxysporum f.sp.lycopeersici.
Keywords:herb  plant pathogen  antifungal activity
