Biological Control Efficacy and Action Mechanism of Klebsiella pneumoniae JCK-2201 Producing Meso-2,3-Butanediol Against Tomato Bacterial Wilt.

ABSTRACT: Bacterial wilt caused by Ralstonia solanacearum is a fatal disease that affects the production of tomatoes and many other crops worldwide. As an effective strategy to manage bacterial wilt, biological control agents using plant growth-promoting rhizobacteria (PGPR) are being developed. In this study, we screened 2,3-butanediol (BDO)-producing PGPR to control tomato bacterial wilt and investigated the action mechanism of the disease control agent. Of the 943 strains isolated from soil, Klebsiella pneumoniae strain JCK-2201 produced the highest concentration of 2,3-BDO. The culture broth of K. pneumoniae JCK-2201 did not show any direct activity on R. solanacearum in vitro, but a 100-fold dilution effectively controlled tomato bacterial wilt with a control value o
