Abstract
Burkholderia glumae causes bacterial panicle blight (BPB) and bacterial seedling rot (BSR) which are difficult to control in rice plants. Seed disinfection using microbes and eco-friendly materials is an efficient alternative practice for managing BPB and BSR. In this study, we applied Cytobacillus firmus JBRS159 (JBRS159) in combination with silicon dioxide (SiO2) nanoparticle or potassium silicate (K2SiO3) solution to control BSR. JBRS159, SiO2 nanoparticle, and K2SiO3 independently suppressed the BSR disease and promoted growths of rice and Arabidopsis. Population of B. glumae in the treated rice seeds was suppressed by the application of JBRS159 via competitions for nutrients and niches. The mixture of JBRS159 and each Si compound (SiO2 nanoparticle or K2SiO3) was complementary for disease-suppressing and growth-promoting activities of individual treatment. The results of this study indicate that mixture of JBRS159 with each Si compound can be harnessed for disease control and growth promotion as efficient alternatives to chemical pesticides and synthetic fertilizers. The efficacy of JBRS159 and Si compounds in the control of BSR and BPB in the field remains to be evaluated.
