The invention belongs to the technical field of prevention and treatment of plant diseases and relates to a bacillus amyloliquefaciens strain capable of preventing and treating wheat scab and application thereof. The preservation number of the separated bacillus amyloliquefaciens S76-3 is CCTCC NO:M2014315, and nucleotide of 16S rDNA of the separated bacillus amyloliquefaciens S76-3 is shown in SEQ ID NO:1. The invention discloses separation, identification and broad-spectrum bacteriostasis of the bacillus amyloliquefaciens, spore yield fermentation optimization of the bacillus amyloliquefaciens and field application of the bacillus amyloliquefaciens in prevention and treatment of wheat scab. The liquid inoculant of the bacillus amyloliquefaciens fermentation diluent can be used for effectively inhibiting the wheat scab and harm in the field and reducing toxins in wheat ears. The bacillus amyloliquefaciens strain has strong stress resistance and does less harm to the environment, so that the bacillus amyloliquefaciens strain can be taken as an efficient antibiological inoculant; and the bacillus amyloliquefaciens is broad in antibacterial spectrum and can be used for inhibiting growth of ten plant pathogenic fungi including fusarium graminearum, so that the bacillus amyloliquefaciens strain has a good development and application prospect.
