Abstract

The invention relates to the field of biological control, in particular to a ralstonia solanacearum bacteriophage Mulvp3 with a wide host spectrum and application thereof. The bacteriophage Mulvp3 is preserved in the China Center for Type Culture Collection on November 6, 2024, and the preservation number of the bacteriophage Mulvp3 is CTCC M 20242438. The bacteriophage Mulvp3 has specificity to ralstonia solanacearum, is wide in host spectrum and wide in applicable pH range, does not have genes related to virulence functions, does not contain genes related to lysogenic-cleavage control, is a virulent bacteriophage, and has great advantages in biological control and safety application of mulberry bacterial wilt.
