Antifungal Effects of Silver Phytonanoparticles from <i>Yucca shilerifera</i> Against Strawberry Soil-Borne Pathogens: <i>Fusarium solani</i> and <i>Macrophomina phaseolina</i>

Abstract

In the present study, the characterization and properties of silver nanoparticles from <i>Yucca shilerifera</i> leaf extract (AgNPs) were investigated using UV-visible spectroscopic techniques, zeta potential, and dynamic light scattering. The UV-visible spectroscopic analysis showed the absorbance peaked at 460 nm, which indicated the synthesis of silver nanoparticles. The experimental results showed silver nanoparticles had <i>Z</i>-average diameter of 729 nm with lower stability (195.1 mV). Additionally, our dates revealed that AgNPs showed broad spectrum antagonism (<i>p</i> ≤ .05) against <i>Fusarium solani</i> (83.05%) and <i>Macrophomina phaseolina</i> (67.05%) when compared to the control after nine days of incubation. Finally, AgNPs from leaf extracts of <i>Y. shilerifera</i> may be used as an agent of biocontrol of microorganism of importance. However, further studies will be needed to fully understand the agronanotechnological potentialities of AgNPs from <i>Yucca schidigera</i>.
