Abstract

Phage-based biocontrol is emerging as a promising alternative to chemical pesticides for managing bacterial pathogens in agriculture. This review offers a comprehensive analysis of the mechanisms through which bacteriophages, viruses that infect bacteria, exert biocontrol effects, with a particular emphasis on their lytic cycle and the complex interplay of phagehost interactions. Target bacterial pathogens such as Pseudomonas syringae, Xanthomonas spp., and Ralstonia solanacearum, which pose significant threats to crop health and yields, are identified. The review further elaborates on the strategies for the selection and characterization of phages, including isolation methods, host range determination, and the assessment of efficacy and stability. Insights from field trials and case studies that evaluate the real-world effectiveness of phage-based biocontrol are discussed, encompassing disease control efficacy, crop yield improvements, and economic considerations. Despite the promise, challenges such as phage stability, narrow host range, bacterial resistance, and regulatory hurdles are acknowledged. The review concludes with an overview of future perspectives, highlighting the potential of engineered phages, development of phage cocktails, and integration with other sustainable agricultural practices. Through multidisciplinary research and innovation, phage-based biocontrol holds the potential to revolutionize crop protection, contributing to more sustainable agriculture and enhanced global food security.
