Abstract: In this study, the catalyst for the synthesis of AgNPs was the supernatant of the soil-borne pathogen Bacillus mn14. S. viridans and R. solani showed susceptibility to the antibacterial and antifungal activity of Bs-AgNPs at concentrations of 70 L and 100 L. According to minimal inhibitory action and a growth-stimulating hormone-indole acetic acid (IAA) study of the isolates, the enzyme properties of the isolates were expressed in TLC as a purple color with an Rf value of 0.7. Small-sized AgNPs with a surface plasmon resonance (SPR) peak at 450 nm were detected using UV/VIS spectroscopy. The particle size analyzer determined that the particles’ average diameter was 40.2 nm. The face-centered cubic type and crystalline nature of the silver nanoparticle were confirmed by the X-ray diffraction study. The silver nanoparticle’s globular, tiny, round shape was identified by scanning electron microscopy. The silver nanoparticle’s two-dimensional topology was revealed by AFM, and its typical size is in the range of 50 nm. Confocal microscopy revealed that S. viridans treated with Bs-AgNPs had their cell walls disrupted. R. solani’s mycelia were found to have been destroyed after being exposed to Bs- AgNPs by high-content screening and compound microscopy. Additionally, the Bs-AgNPs improved the root and shoot length of Oryza sativa seeds and reduced the length of lesion in the treatment of sheath blight disease. This method of synthesizing AgNPs using the soil-borne pathogen Bacillus appears to be economical, environmentally friendly, and farmer-friendly, and it offers a simple way to produce valuable, nutrient-dense foods in the future.
