The aim of this study was to isolate endophytic bacteria from different tissues of commercial rice varieties and to test in vitro their antibacterial activity against Burkholderia glumae causing bacterial blast disease of rice. The results of this study report a high diversity of culturable endophytic bacteria with the ability to produce secondary metabolite type extracts with the capacity to inhibit in vitro the growth of B. glumae. The results obtained from the extracts at different extraction times have similar effects to that shown by the chemical control with oxolinic acid. Further studies will identify the groups of metabolites produced by these bacteria and their possible use for field management of B. glumae.
