SUMMARY
In current context, there is an imperative need to conduct rigorous research on biopolymerderived substances. In this study, we evaluated the effect of Cu-chitosan nanoparticles against Post Flowering Stalk Rot (PFSR) under field condition in maize. Cu-chitosan nanoparticles were prepared using ionic gelation technique. After disease inoculation inhibition effect of nanoparticles were analyzed to determine antifungal activities against PFSR. In field experiments it is proved that Cuchitosan nanoparticles at the concentration of 0.06% expressed strong antifungal activity in controlling PFSR disease in 4hrs treated surya local variety. Thus, our study shows that Cu-chitosan nanoparticles could be a new generation for disease control in field condition.
Key words:Cu-Chitosan nanoparticles, Maize, PFSR, ionic gelation
