Antifungal activity of silver nanoparticles against Rhizoctonia solani Kühn
Abstract
Sheath Blight caused by Rhizoctonia solani Kühn is the second most devastating disease in rice. Managing the causal agent becomes difficult as it produces sclerotia that survive even in adverse environmental conditions. Silver nanoparticles (AgNPs) are increasingly recognized for their strong antimicrobial properties. The study aimed to assess the antifungal effect of silver nanoparticles at different concentrations against R. solani Kühn under in vitro condition using poisoned food technique. The statistical analysis revealed a high significant variation among treatment means from 3 days until 7 days of incubation. Based on the results, the ability of AgNPs to suppress the growth of R. solani Kühn improves with increasing nanoparticle concentrations, indicating a concentration-dependent inhibitory effect.
