Study on the effect of nano-silver synthesized by gamma radiation in combination with zinc-EDTA on chrysanthemum white rust caused by Puccinia spp. in chrysanthemum

Abstract

Antifungal effects of nano-silver synthesized by gamma radiation in combination with zinc-EDTA on Puccinia spp., the causal agent of the chrysanthemum white rust disease, were investigated. The effect of nanosilver in combination with zinc-EDTA on the growth of chrysanthemum plant and the chrysanthemum white rust control was experimented in vitro and under greenhouse condition. The results showed that nano-silver with zincEDTA strongly inhibited the chrysanthemum white rust causal pathogen Puccini spp. When nano-silver with zinc-EDTA was applied as a fungicide, the chrysanthemum white rust incidence in chrysanthemum reduced by 100%, and growth parameters of chrysanthemum plants significantly increased as compared to the corresponding control. The objective of this study was to evaluate the effect of nano-silver synthesized by gamma radiation in combination with zinc-EDTA on the chrysanthemum plant growth promotion and control of the chrysanthemum white rust disease in chrysanthemum.
