Summary:[ Objectives] The paper was to study effects of different microbial agents on occurrence of tobacco bacterial wilt. [ Methods I Antagonistic strains against Ralstonia solanacearum were screened from in situ soil, and prepared into four different combinations. The number of soil microorganisms and incidence of bacterial wilt of four combinations were observed. [ Results] The incidence rate of bacterial wilt treated by microbial agent OR-1 was significantly lower than that in control, and the control efficacy against bacterial wilt reached 67%. [ Conclusions] Application of microbial agent OR-1 could effectively reduce the incidence rate and disease index of bacterial wilt, thus improving the quality of tobacco.
