[Problem] To provide a new strain not pathogenic to plants which exhibits a stable bacterial plant disease control effect at real crop production sites and which can be safely used as a biological pesticide, and to provide a bacterial plant disease control agent using said strain. [Solution] By using, as an active component, live bacteria, or a culture containing said live bacteria, of the Ralstonia pickettii TCR 112 strain (NITE BP-02446), it is possible to provide a bacterial plant disease control agent such as a vegetable wilt disease control agent or a surface rot control agent.
