The purpose of this study was to evaluate Cu-chitosan NCPs for its antifungal activities against Fusarium verticillioids causing post flowering stalk rot (PFSR) disease of maize. Cu-chitosan NCPs were prepared based on the ionic gelation of chitosan with tripolyphosphate anions and Copper ions having particle size (295.4 nm), polydispersity index (0.28), zeta potential (+ 19.6 mV).Various concentrations of Cu-chitosan NCP was applied in pot and field experiments.Cu-chitosan NCPs at the concentration of 0.1% and 0.14% found effective in controlling PFSR in pot experiments. In Surya local (4 hrs treated seeds) PEDC was 48.1% at 0.1% Cu-chitosan NCP. In Surya local (8 hrs treated seeds) 49.6% PEDC was observed at 0.1 and 0.14% Cu-chitosan NCPs. In field experiments, Cu-chitosan NCP at the concentration of 0.06% found effective in controlling PFSR disease. Significant disease control of PFSR was observed (33.9%) at 0.06% Cu-chitosan NCPs in Surya local (4 hrs treated seeds). All together Cu-chitosan NCPs have remarkable potential and act as an effective antifungal agent against PFSR of maize in pot condition as well as in field condition for crop protection.
