摘要

Management to control bacterial wilt of potato caused by Ralstonia solanacearum (RS) (Syn. Pseudomonas solanacearum) race 3, biovar Ⅱ was carried out by amending infested soils with stable bleaching powder (SBP) and a mixture of urea and lime (urea-lime) at different concentrations and combinations under glasshouse and field conditions of Nepal. Soils infested with RS were treated with either SBP or urea-lime mix two weeks before planting with the highly susceptible and healthy potato seeds cultivar Kufri Jyoti.
