Plant diseases are still the main problem for reduction in crop yield and a threat to global food security. Additionally, excessive usage of chemical inputs such as pesticides fungicides control plant have created another serious human environmental health. In view this, application growth-promoting rhizobacteria (PGPR) controlling disease incidences has been identified an eco-friendly approach coping with security issue. this review, we different ways by which PGPRs capable reducing phytopathogenic infestations enhancing yield. PGPR suppresses diseases, both directly indirectly, mediated microbial metabolites signaling components. Microbial synthesized anti-pathogenic siderophores, antibiotics, lytic enzymes, hydrogen cyanide, several others act on phytopathogens. The indirect mechanisms infestation caused stimulation immune responses known initiation systemic resistance (ISR) is triggering elicited through pathogen-associated molecular patterns (PAMPs). ISR triggered infected region leads development acquired (SAR) throughout making resistant wide range pathogens. A number including Pseudomonas Bacillus genera proven their ability stimulate ISR. However, there some challenges large-scale acceptance pest management. Further, discuss newly formulated inoculants possessing activities suppression holistic sustaining health productivity.
