[Objective] The research aimed to study the biological control ability of Bacillus cereus63305. [ Method ] The effects of growth-promoting and insecticidal of Bacillus cereus CMCC63305 were studied through the germination, antimicrobial and leaf disc method. [Result] B.cereus CMCC63305 could stimulate root growth, increased wheat dry weight of fresh material accumulation, compared with the control, fresh weight increased by 9.08%-13.00%, dry weight increased by 9.22%-12.90%, plant height increased by 1.24%-5.57%. 10~6 cfu/ml broth had the capability of antagonism against Rhizoctonia cerealis, the inhibition rate on mycelial growth reached to 86.07%, a bit lower than that of carbendazol. The inhibition rate on gray mold was 63.73%, higher than that of check sample.1.83×10~(10) cfu/ml Bacillus cereus killed 84.3% of the third instar larvae in 48 h. It was a bit lower than that of 1.14×10~(10) cfu/ml Bacillus thuringiensis Bt0601 which killed 96.7% of the third instar larvae in 48 h. [ Conclusion ] Bacillus cereus 63305 had the ability of plant-growth promotion, antagonism against some disease and kill the third instar larvae.
