Bacteriophages in preventing bacterial wilt on marigold caused by Ralstonia solanacearum
View through CrossRef
Bacterial wilt caused by Ralstonia solanacearum is a severe disease in many vegetable and ornamental plants. This research was conducted to screen promising bacteriophages for controlling bacterial wilt in marigold under laboratory and greenhouse conditions. The lytic capability of twenty bacteriophages parasited nine strains of R. solanacearum causing bacterial wilt in marigolds and other crops. The results showed that all bacteriophages were able to parasitize all bacterial strains examined. A lytic ability assessment of the twenty bacteriophages lysis on R. solanacearum on marigolds revealed that three phages ФOM, Ф1G, and ФĐT3 gave strong bacterial lysis through high titer multiplication. Additionally, phage Ф2D and ФOM observed large plaque diameter compared to others. The three phages ФOM, Ф1G, and ФĐT3 were selected for further evaluation of their effectiveness in controlling bacterial wilt caused by R. solanacearum in marigold under greenhouse conditions. In which, phage ФOM provided the most effective disease control and showed a significantly lower disease incidence compared to other treatments.
