Phage therapy for plant disease control with a focus on fire blight

Abstract

AbstractThe concept of using bacteriophages (bacterial viruses) as biocontrol agents in pest management emerged shortly after their discovery. Although research on phage-based biopesticides temporarily stopped with the advent of antibiotics, the appearance of antibiotic resistant bacterial strains led to a renewed interest in phage therapy for control of plant diseases. In the past twenty years numerous successful experiments have been reported on bacteriophage-based biocontrol measures, and several comprehensive studies have recently been published discussing detailed results of phage application practices in pest management, mainly from North American authors. The present review focuses on bacteriophage-mediated control of fire blight (caused by Erwinia amylovora (Burill) Winslow et al.), the most devastating bacterial disease of pome fruits. Research results from North America are discussed along with recent data from European laboratories.
