GREEN SYNTHESIS OF Ag-DOPED CuO NANOPARTICLES AND THEIR ANTIBACTERIAL AND ANTIFUNGAL APPLICATIONS ON CAMELLIA CHRYSANTHA IN BA CHE COMMUNE, QUANG NINH PROVINCE
Overview
Abstract:
| This study successfully synthesized Ag-doped CuO nanoparticles using a green method with papaya leaf extract. The antibacterial and antifungal activities of the Ag-doped CuO nanoparticles, together with CuO and Ag control samples, were evaluated against two representative strains, the bacterium Pseudomonas syringae and the fungus Pestalotiopsis mucronatum. The Ag-doped CuO nanoformulation was sprayed onto golden camellia (Camellia chrysantha) plants infected with rust and leaf spot diseases in Ba Che commune, Quang Ninh province. The results indicated that the suspension containing Ag-doped CuO nanoparticles exhibited strong antibacterial and antifungal activities, in which the inhibitory effect against P. syringae was superior to that of the individual Ag and CuO nanoparticles; similar results were observed for P. mucronatum. After seven days of treatment, rust and leaf spot symptoms on golden camellia plants were markedly reduced. All plants in the experimental area showed healthy growth and development. |
