An experiment was conducted to find out the effective antibacterial chemicals and bioagents against the growth of Ralstonia solanacearum under in vitro conditions. Average inhibition was ranged from 6.2 mm (Copper hydroxide) to 20.05 mm (Streptocycline). However, significantly highest average inhibition was recorded in the antibiotic Streptocycline (20.05 mm). This was followed by the antibiotics viz., Gentamycin (17.5 mm), Tetracycline (16.5 mm) and Copper oxychloride + Streptocycline (11.95 mm). All the bioagents evaluated exhibited antibacterial activity against R. solanacearum. The antagonistic microorganism Pseudomonas fluorescens resulted in maximum inhibition of the Ralstonia solanacearum with an inhibition zone of 24.33 mm which was found significantly superior over other treatments. The second and third best antagonists found were Trichoderma viride and Bacillus subtilis with an inhibition zone of 21.17 mm and 19.33 mm, respectively.
