Liu YuSheng

Open publisher page 2 citations

Abstract

In this paper,identification of species Bf-02 was studied.By observation of the morphological character,cultivation properties,measurement of the biochemistrical features,the strain was identified as Bacillus firmus.Through dual-culture,the inhibitory spectrums and inhibition efficacy were tested.The results showed that it had antifungal activity to all the pathogens tested except Sclerotium rolfsii.It had the better inhibitory effect to Colletotrichum gloeosporioides,Bipolaris sorokiniana,Alternaria alternata,Botrytis cinerea,Alternaria alternata,Fusarium oxysporum f.sp.vasinfectum,Physalospora piricola.The inhibitory rate could reach up to 70% or more.So,Bf-02 had the broad spectrums and was worth studying further for it's important potential to restrain the pathogens.
