Abstract In South Asia, bacterial wilt pathogens in the Ralstonia solanacearum species complex (RSSC) impose major constraints on eggplant, tomato, and pepper production. To improve the efficacy of bacterial wilt management, the goals of this study were to (1) conduct a survey of RSSC pathogens in Bangladesh and Nepal, (2) characterize the genetic diversity of these isolates, and (3) screen 37 tomato, eggplant, and pepper accessions for resistance to six representative isolates from South Asia.
