Abstract: Antifungal efficacy for some oxides of metallic nanoparticles (NPs) e.g. magnesium (MgO), copper (CuO), silicon (SiO2) and zinc (ZnO) was evaluated against fungi, Sclerotinia sclerotioum on bean plants under different conditions. The examined NPs exhibited significant effect on hyphal morphology and fungal linear growth under field trail in the following order: MgONPs> SiO2NPs> ZnONPs> CuONPs compared with control group. However under storage condition, the disease severity along NPs-treated bean pods were in the order: MgONPs> SiO2NPs> ZnONPs> CuONPs compared with infected control which did not exceed 30.23% and non-infected (14.68%). Bean pods treated with NPs showed significantly increase in chlorophyll content, total phenols, and ascorbic acid compared with non-infected pods during storage period for 4 weeks. The examined NPs exhibited positive accumulation in pods tissues, except MgO was lower than non-infected group. The present findings may display the potential effect metal oxides in agricultural sector need more studies to achieve their adverse effects on consumers and environmental impacts.
