Antagonistic Features of Plant Growth Promoting Rhizobacteria PGPRA Sustainable Alternative to Chemical Pesticides

Introduction

Plant growth-promoting rhizobacteria (PGPR) are beneficial soil bacteria that enhance plant growth while protecting against harmful pathogens. These bacteria, residing in the rhizosphere, utilize antagonistic mechanisms such as producing antibiotics, lytic enzymes, and siderophores to suppress plant diseases. As the agricultural industry seeks sustainable alternatives to chemical pesticides, PGPR-based biopesticides emerge as a promising solution.

How PGPR Protect Plants

PGPR exhibit antagonistic behavior through multiple mechanisms, including:

• Antibiotic Production – Certain PGPR strains, such as Pseudomonas fluorescens, produce antibiotics like 2,4-DAPG, which inhibit fungal pathogens.
• Siderophores – These iron-chelating molecules, produced by Bacillus and Pseudomonas species, deprive pathogens of essential nutrients.
• Lytic Enzymes – Enzymes such as chitinases and glucanases break down pathogen cell walls.
• Bacteriocins – Protein-based toxins specifically target harmful bacteria while sparing beneficial microbes.

The Need for Biopesticides

Chemical pesticides, while effective, contribute to environmental pollution and disrupt beneficial microbial populations. The American Society of Agronomy emphasizes the importance of biological control methods to ensure sustainable agriculture. PGPR-based biopesticides offer targeted pathogen suppression without harming the surrounding ecosystem.
