Identification of Antagonistic Fungus against Sphaerotheca fuliginea and Evaluation of Its Biocontrol Efficacy
摘要
Abstract
The antagonistic fungus against the pathogen Sphaerothecafuliginea were isolated and assessed in this paper.The resulted showed that 21 strains of antagonistic fungus were isolated from the edge of cucumber tissue infected by S.fuliginea.Among all the isolated strains,the strain JK-13 presented the highest control efficacy in vitro and greenhouse experiments.The inhibitory rate on S.fuliginea spores germination was 83.93％ after treated by strain JK-13 fermentation broth for 48 h.The control efficacy of strain JK-13 fermentation broth on S.fuliginea were 88.02％ and 76.34％ after treated for 7 d by leaf disc and pot experiments,respectively.Based on the morphological characteristic and molecular identification,the strain JK-13 was identified as Fusarium solani.关键词
