| Summary: | The inhibitory effects of Silver oxide nanoparticles (Ag NPs), Zinc oxide nanoparticles (Zn NPs) as well as Chitosan nanoparticles (Ch NPs) against the causal pathogens of kidney bean root rot comparing with fungicide Topsin-70® Wp were evaluated under greenhouse and laboratory during the summer season of 2023. In the pathogenicity test under greenhouse, based on infection of damping-off or root rot, the isolates No 5 of Sclerotium genus, No 4 of Rhizoctonia, No 1 of Pythium and No 2 of Fusarium were the most aggressive isolates, respectively. In vitro experiment, both fungicide and high level of any of nanoparticles used (30 ppm) entirely suppressed the linear spread of four examined fungal genera (Fusarium solani, Sclerotium rolfsii, Rhizoctonia solani as well as Pythium ultimum). Zn NPs was the most effective followed by Ag NPs. In greenhouse experiment, under artificially contaminated soil with a diverse range of pathogenic fungi, Topsin-70® Wp and all tested nanoparticles as seed soaking treatments led to protecting bean plants against damping-off or root rot infection. The fungicide Topsin-70® Wp was more efficient accompanied by Zn NPs then Ag NPs. This study clearly demonstrated that, there are no statistically important differences among the leverage of nanoparticles as well as fungicide against bean root rot pathogens. |
