Abstract: Nanoencapsulated herbicide materials were synthesized using direct and indirect encapsulation techniques at the Department of Nano Science and Technology, Tamil Nadu Agricultural University, Coimbatore. Ammonium bi carbonate was mixed with manganese sulphate monohydrate solution and ethanol solution the MnCO₃ microcapsules are prepared by altering layer by layer (LbL) adsorption of opposite charge polyelectrolyte. Thus direct and indirect nano encapsulated herbicide particles were analysed using various instruments. The porous rough surface characteristic of MnCO₃ core particles aided in loading of herbicides due to the physical adsorption and also by covalent bonding. The remarkable size, shape, physico-chemical properties of nanoparticles have fascinated and inspired research activity in this direction.
