Abstract

Among various bacterial diseases, bacterial wilt of tomato caused by Ralstonia solanacearum is one of the devastating diseases of tomato (Lycopersicum esculentum) crop. Therefore, present study was undertaken to assess efficacy of six antibiotics and five fungicides against R. solanacearum, applying inhibition zone assay technique. The experiments was planned with CRD and all the treatments replicated thrice. Results revealed that among the antibiotics tested significantly highest zone of inhibition was recorded with Streptocycline (21.16 mm), followed by gentamycin (18.00 mm), tetracycline (16.85 mm), dicrystacine (16.16 mm) and cephalexin (15.15 mm). Among the fungicides tested alone and in combination with antibiotics, significantly highest zone of inhibition was recorded with copper oxychloride + streptocycline (15.16 mm), followed copper oxychloride + tetracycline ( 13.44mm), copper oxychloride (12.72mm) and copper hydroxide (11.83).
