INTRODUCTION: Bacterial wilt (BW) caused by Ralstonia pseudosolanacearum is a devastating soil-borne disease. Bacteriophages are important biocontrol resources that rapidly and specifically lyse host bacteria, showing good application potential in agricultural production. METHODS: This study isolated nine phages (YL1-YL9) and, using host range and pot experiments, identified two broader host range phages (YL1 and YL4) and two higher control efficacy phages (YL2 and YL3), which were combined to obtain five cocktails (BPC-1-BPC-5). RESULTS: Pot experiments showed that BPC-1 (YL3 and YL4) had the...
