Plant growth promoting fungi (PGPF)-based nanoparticles (NPs) have emerged as promising tools in agricultural practices due to their multifaceted benefits for plant growth and health. These nanoparticles, derived from beneficial fungi, serve as carriers for various bioactive compounds and metabolites that stimulate plant growth and enhance their resilience against environmental stresses. One of the principal benefits of PGPF-based nanoparticles is their capacity to improve nutrient uptake in plants by solubilizing essential nutrients such as phosphorus and iron present in the soil, thus making them more readily available to plant roots. Additionally, PGPF nanoparticles can produce phytohormones and other growth promoting substances that regulate plant growth and development processes, leading to improved crop yields. Furthermore, PGPF-based nanoparticles exhibit biocontrol properties against phytopathogens by producing antifungal and antibacterial compounds, thereby reducing the incidence of plant diseases and minimizing the need for chemical pesticides. The utilization of PGPF-based nanoparticles represents a promising approach to improving agricultural productivity while minimizing the environmental impact of conventional farming practices.
