Plant Pathology, Microbial Biotechnology, and Rhizosphere Engineering for Sustainable Disease Management

Abstract

Plant diseases continue to pose a major threat to global agricultural productivity, food security, and environmental sustainability, necessitating innovative and eco-friendly approaches for disease management. The integration of plant pathology, microbial biotechnology, and rhizosphere engineering has emerged as a promising strategy for developing sustainable crop protection systems that reduce reliance on chemical pesticides while enhancing plant health and resilience. This review paper examines recent advances in plant pathology, microbial biotechnology, and rhizosphere engineering for sustainable disease management. The study explores the interactions among plants, pathogens, and beneficial microorganisms within the rhizosphere, emphasizing the roles of plant growth-promoting rhizobacteria (PGPR), endophytic microorganisms, mycorrhizal fungi, biocontrol agents, and microbial consortia in suppressing soil-borne and foliar pathogens. Furthermore, the review discusses the application of microbial biotechnology, including microbial inoculants, biofertilizers, biopesticides, synthetic microbial communities, metagenomics, and genome-editing technologies, for improving disease resistance and maintaining rhizosphere health. Recent advances in microbiome engineering, multi-omics technologies, artificial intelligence, precision agriculture, and biosensor-based monitoring are also evaluated for their potential to optimize rhizosphere functions and enable climate-smart disease management. Despite significant progress, challenges related to microbial establishment, environmental variability, field-level consistency, regulatory frameworks, and commercialization continue to limit large-scale adoption. This review synthesizes current developments and highlights the transformative potential of integrating plant pathology, microbial biotechnology, and rhizosphere engineering to promote sustainable disease management, enhance crop productivity, and strengthen agricultural resilience.
