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.
