Summary

The escalating threats posed by plant pathogens and the environmental repercussions of conventional agrochemicals necessitate sustainable agricultural solutions. This review focuses on plant growth-promoting microorganisms (PGPMs) such as bacteria, filamentous fungi, and yeasts, which play a pivotal role as biocontrol agents. These organisms enhance plant growth and resilience through nutrient solubilization, phytohormone production, and antagonistic activities against pathogens, offering a dual benefit of disease suppression and growth enhancement. However, the effective application of PGPMs faces challenges, including variability in field performance, survival and colonization under field conditions, and regulatory hurdles. This paper discusses these challenges and explores recent advanc
