QIU Qi et al(College of Natural Resource and Environment,South China Agricultural University,Guangzhou,Guangdong 510642)  
[Objective] The aim of this paper was to provide the theoretic references for further exploition plant fungicides.[Method] Mycelial growth rate method was adopted to determine and analyse antibacterial activity of methanol extracts from 21 species plants against 3 species fungi which contained Alternaria solani,Cladosporium fulvum and Ceratocystis paradoxa.[Result] The results indicated that the inhibition rates of extracts of Camellia sinensis and Solanum torvum against Alternaria solani was 76.67% and 78.08% when the concentration was 10 mg/ml,while,the inhibition rates of extracts of Cymbopogon citrates and Michelia maudiae against Cladosporium fulvum was 100 % and 69.20%.The inhibition rates of extracts of Camellia oleifera and Glycyrrhiza uralensis against Ceratocystis paradoxa was 100% and 74.02% at the same concentration.[Conclusion] The antibacterial activity of methanol extracts from Camellia sinensis and Glycyrrhiza uralensis against 3 species fungi of fruit or vegetable were superior to other methanol extracts.
