Abstract:
Tomato (Solanum lycopersicum L.) is one of the most prevalent vegetable food crops in the world, Ralstonia solanacearum causing vegetable bacterial wilt in tomato is the most destructive pathogen across the world, in the present investigation five antibacterial chemicals (three antibiotics, one fungicide and one plant derived antibacterial chemical) were evaluated for their efficacy against bacterial wilt pathogen in vitro condition. Among all the treatments at different concentrations streptocycline 500 ppm produced highest inhibition zone of 20.00 mm, followed by 2 Bromo – 2 Nitropropane – 1, 3 – diol (bacterinash) 500 ppm showed 18.40 mm inhibition zone whereas streptocycline 300 and 150 ppm produced inhibition zone of 17.60 and 15.80 mm respectively, after that 2 Bromo – 2 Nitropropane – 1, 3 – diol produce a moderate effect with 15.40 and 13.40 mm at 300 and 150 ppm concentrations respectively, followed by copper oxychloride produce 8.80 mm and bacterisan produce 7.40 mm inhibition zone at 500 ppm concentrations. However at 150 and 300 ppm concentrations, both bacterisan and copper oxychloride and all concentrations of validamycin did not form any inhibition zone.
