摘要

[Objective] The paper was to identify strain HN-1 against banana wilt disease and to determine its antagonism.[Method] The strain HN-1 was obtained from the soil in fields heavily infected by Fusarium oxysporum f.sp.cubense( FOC).Antagonism of the strain against F.oxysporum was tested via dual-culture and inhibition test on spore germination.[Result] HN-1 effectively inhibited mycelial growth and spore germination of F.oxysporum.Strain HN-1 was identified as Brevibacillus brevis according to its characteristics in morphology,physiology and biochemistry and its 16S rDNA sequence.The strain showed high inhibition effect on 15 species of fungal pathogens in the dual-culture trials with fungal pathogens.[Conclusion] The study provides theoretical basis for application of strain HN-1in agricultural fields.
