Integrated management of bacterial wilt of brinjal incited by Ralstonia solanacearum

An experiment was conducted to find out the effective treatments for integrated management of Ralstonia solanacearum infecting brinjal Cv. Puneri Kateri. All the treatments found effective with reduction of mortality in the range of 46.38 to 75.23 per cent over untreated control. However, significantly highest reduction mortality was recorded with RDF + 66g Gypsum/kg soil + Copper oxychloride 2500 ppm + Streptocycline 300 ppm (75.23%), followed by Neem seed kernel extract 20% + Copper oxychloride + Streptocycline (73.84), Noni fruit extract 20% + Copper hydroxide + Streptocycline (72.68%), Vermicompost + Seed + root + soil treatment with Pseudomonas fluorescens (70.83%), Copper oxychloride + Streptocycline (69.67%), Seed + root + soil treatment with P. fluorescens (68.15%), root + soil treatment with P. fluorescens found similar (66.97%). Copper hydroxide + Streptocycline (66.66%), Vermicompost (65.47%), RDF + 66gm gypsum/kg soil (62.20%), Neem seed kernel extract 20% (56.51%) and Noni fruit extract 20% (46.38%) found effective in mortality reduction.
