Abstract
Silver nanoparticles (AgNPs) are gaining significant attention in agriculture due to their potent antifungal properties. This study focuses on evaluating the antifungal effects of green synthesized AgNPs derived from Aloe vera leaf extract against the pathogenic fungus Aspergillus niger. The results indicate that the synthesized nanoparticles exhibited a strong absorption maximum at 550 nm, indicative of surface plasmon resonance. UV-Vis spectroscopy was used to analyze the nanoparticles, and the solution exhibited faint red color characteristics. The synthesized AgNPs demonstrated significant antifungal activity against Aspergillus niger. To assess this, silver nanoparticle solution was mixed with PDA media and poured into petri plates, onto which fungal discs were placed. After incubating for 24-48 hours, it was observed that the fungus did not grow on the media containing the silver nanoparticle solution. These findings suggest that Aloe vera leaf extract-based silver nanoparticles have a promising potential for controlling pathogenic fungi. Additionally, the application of AgNPs was found to enhance morpho-physiological attributes in wheat and reduce nanoenzymatic compounds and antioxidant enzyme levels. This study underscores the potential of green synthesized AgNPs not only as a biological control agent for various fungal species but also as a means to improve agricultural productivity. Further research is needed to explore the size-dependent efficacy of AgNPs on different fungal species and to fully understand their impact on crop health and yield.
