<p>One of the factors affected production of tomato is the incidence of bacterial wilt disease caused by <em>Ralstonia solanacearum</em>. An alternative control to manage the disease which is environmentally friendly is the use of biocontrol agents. Application of endophytic bacteria (<em>Staphylococcus epidermidis</em> BC4) and plant growth promoting rhizobacteria (<em>Pseudomonas fluorescens</em> RH4003 and <em>Bacillus subtilis</em> AB89) as biocontrol of tomato bacterial wilt was expected to be an alternative method. The objective of this study is to evaluate the interaction among endophytic bacteria and PGPR to suppress the development of bacterial wilt disease (<em>R. solanacearum</em>) and promoting the growth of tomato. Bacterial treatment which caused the highest suppression on disease incidence was single application of <em>P. fluorescens</em> RH4003. Disease index caused by <em>S. epidermidis </em>BC4 and <em>P. fluorescens</em> RH4003 applied individually was up to 41.18 dan 45.88%, respectively. Interaction between the endophytic bacteria and both of the PGPRs were antagonistic.</p>
