Abstract

The invention discloses a biopesticide composition for tobacco bacterial leaf blight. The biopesticide composition is composed of pyrisoxazole tetramycin, Zhongshengmycin and oligosaccharins. By compounding and mixing pyrisoxazole tetramycin, Zhongshengmycin and oligosaccharins with the concentration ratio being 3:4:2, the tobacco bacterial leaf blight field control effect of the composition can reach 83% or above, and the prevention effect is remarkable. The composition has the advantages of being efficient, environmentally friendly, safe, low in cost and the like.
