| Abstract: | 127 bacterial strains were isolated from rhizosphere soils.The result of plate test showed that six strains had antagonistic activity against the tobacco wildfire disease.In pot experiment,strain S_1 had a protective efficiency of 85.98% and therapeutic efficiency of 76.95% against the tobacco wildfire disease.In addition,strain S_1 appeared promoting effect on the tobacco growth.This strain was identified as Bacillus subtilis. |
