Online Published on 30 March, 2022. Abstract Background Management of bacterial wilt of tomato in Ralstonia solanacearum affected soils is a major issue in tomato cultivation in different agro-ecological regions in Kerala state which affects the production and productivity of the crop. To develop a suitable management protocol for this disease, the field experiments were conducted during 2019 and 2020 in a bacterial wilt-sick field at Kerala Agricultural University, Thrissur, Kerala, India. Methods Twelve different treatments viz. soil application of bleaching powder, soil test based lime application, streptocycline root dip, drenching of copper hydroxide and copper oxychloride at different doses, seed treatment and seedling dip with Pseudomonas fluorescens, drenching of Pseudomonas fluorescens, planting grafted seedlings and different integrations and combinations of the above treatments were assessed for the management of bacterial wilt. Result The majority of integrations were superior over individual treatments. The higher yield with less disease incidence was obtained from the integration of soil treatment of bleaching powder (15 kg/ha) + soil test based lime application + streptocycline (@ 2 g/10 L) root dip + drenching of copper oxychloride (@ 0.3%) and therefore, this integration protocol is recommended for management of bacterial wilt of tomato in wilt affected soils in Kerala state.
