Abstract:
Brinjal (Solanum melongena) is considered as the second most important vegetable crop in India. Bacterial wilt caused by Ralstonia solanacearum was the major constraint in brinjal. The antibacterial activity of 24 ethanol phytoextracts were investigated against the bacterial wilt pathogen Ralstonia solanacearum under in vitro by agar well diffusion method at 10% and 20% concentrations. Among all the 24 botanicals tested, Allium sativum, showed maximum inhibition zone of 10.62 mm followed by Allium cepa showed 10.32 mm respectively at 20% concentration. At 10% concentration, maximum inhibition zone was observed in Ocimum sanctum 3.93 mm followed by Zingiber officinale showed 3.29 mm respectively.
