In order to control this bacterium, a biological control approach has been considered by evaluating the efficacy of the NECO biopesticide against this bacteriosis<em>. In vitro</em> confrontations were carried out using a range of five concentrations of the biopesticide. <em>In vivo</em>, NECO solutions of 5 and 10 mL/L were incorporated into soil previously infested with <em>R. solanacearum</em> before transplanting tomato plants.</p><p>Zones of bacterial growth inhibition were observed after the application of the NECO biopesticide. Results showed that the 20 mL/L concentration resulted in a higher inhibition rate. The biopesticide at the 10 mL/L concentration significantly reduced the incidence of bacterial wilt (54.05%) under in vivo conditions. The NECO biopesticide could be used as a control agent for <em>Ralstonia solanacearum</em>.</p> ER -
