This study was conducted to evaluate the in vitro antibacterial activity of some medicinal plants against Ralstonia solanacearum. Bioactive chemicals were extracted from Burcea antidysenterica, Eucalyptus citriodora, Justicia schimperiana, Lantana camara, Melia azedarach and Ricinus communis leaves using maceration method. The bioassay was evaluated by disc diffusion method. The pathogen was isolated from infected Capsicum annuum plants using Casamino acid-Peptone-Glucose agar (CPG) medium. The isolate was identified using cultural, biochemical characteristics, pathogenicity test and found to be R. solanacearum. The methanol extracts had different composition, percentage extract yield, antibacterial activity and relative percentage inhibition. Unlike...
