| ACT A Commercial product of Copper oxide nanoparticles (CuONPs) that chemically synthesis showed spherical plats with size (11.4-16nm) was concerned in this study singly or combined with peroxy acetic acid (PAA) to explore a proper control approached towards sesame wilting fungus Fusarium oxysporum f. sp. sesame. Using CuONPs as seed socking gave somewhat toxic effect toward sesame seed germination specially at100 mg/L CuONPs concentration more than PAA. However, CuONPs when it applied singly, improved seed germinations under Fusarium oxysporum infection more than PAA alone. A synergistic effect was provided when CuONPs was combined with PAA in this respect. As for fungal growth, a substantial antifungal activity was more addressed by CuONPs than PAA. Meanwhile, combining CuONPs with PAA explored the most inhibitory effect toward mycelial dry weight of the pathogen. Furthermore, F. oxysporum f. sp. sesame infectivity was strongly suppressed by CuONPs compared with PAA, but its infectivity was the most suppressed by combining treatments and considered as additional values for use low CuONPs concentrations that save environmental clean and human health. | ||||
