ABSTRACT
Nanoscience and nanotechnology are concerned with the understanding and rational manipulation of materials at the atomic and molecular levels, generally with structures of less than 100 nm in size. Nanotechnology has the potential to revolutionize the agricultural and food industry with new tools for the molecular treatment of diseases, rapid disease detection, and enhancing the ability of plants to absorb nutrients. Weeds are menace in agriculture. Herbicides are designed to control or kill the above ground part of the weed plants. Nanotechnology offers the potential of novel nanomaterials for the treatment of surface water, groundwater and wastewater contaminated by toxic metal ions, organic and inorganic solutes and microorganisms. Identity Preservation is a system that creates increased value by providing customers with information about practices and activities used to produce a particular crop or other agricultural products. One of the processes using nanoparticles is photocatalysis. Photocatalysis can be used for purification, decontamination and deodorization of air.
