Abstract:
Potato (Solanum tuberosum L.) is one of the important food crops. Ralstonia solanacearum causing bacterial wilt of potato, considered as destructive disease of potato crops. It has an extensive host range of ~ 450 crop species across 54 families. In the present research work six antibacterial chemicals (3 antibiotics & 3 bactericides) were evaluated against R. solanacearum. Among the antibiotics Chloramphenicol showed highest antibacterial activity at 100ppm and 250ppm (15.96 and 19.60 mm inhibition zone respectively) whereas at 500ppm Streptocycline produced highest inhibition zone (28.03 mm). Among the bactericides Azoxystrobin showed highest antibacterial activity at all the three concentrations (0.1%, 0.2% and 0.3%) produced inhibition zone 10.10mm, 11mm and 12.26 mm respectively.
