Residual analysis of chitosan-based agronanofungicides as a sustainable alternative in oil palm disease management

Abstract The nanoformulations of pesticides have shown great interest from many parties due to their slow release capability and site-specific delivery. Hence, in this work, a new nanoformulation of a fungicide, namely chitosan-hexaconazole nanoparticles with a mean diameter size of 18 nm was subjec...
