The present invention provides a virulent Pseudomonas fluorescens (P. fluorescens) phage ΦPf1901, and a phage ΦPf1901 preparation and an application thereof, and relates to the technical field of phage. The virulent P. fluorescens phage ΦPf1901 has an accession number of CCTCC M2019447. The virulent phage ΦPf1901 has a titer of (1.4-3)×1010 PFU/mL. The virulent phage ΦPf1901 has an optimal multiplicity of infection (MOI) value of 0.0001. The virulent P. fluorescens phage ΦPf1901 provided by the present invention exhibits very high specificity and lytic ability to P. fluorescens, which can be used to control P. fluorescens, with strong lytic and scavenging effects on a host.
A method for inhibiting P. fluorescens, comprising the step of contacting P. fluorescens phage ΦPf1901 with a virulent P. fluorescens phage at a temperature of 20-50° C. and at a pH value of 5 to 11;
