Abstract

Compared to conventional or other contaminants, nanoparticles pose some new environmental challenges for scientists and environmentalists worldwide. Nanotechnology will leave no field untouched including agriculture by its ground breaking scientific innovations. So far, the use of nanotechnology in agriculture has been mostly theoretical, but it has begun to have a significant effect in the main areas of the food industry. Nanoparticles finding great potential as delivery systems to specific targets in living organisms and is being used in medical sciences. In plants, the same principles can be applied for a broad range of uses, particularly to tackle phytopathological infections, nutrition supplement and as growth adjuvant. Nanoparticles can be tagged to agrochemicals or other substances as delivery agent to plant system and tissues for controlled release of chemicals. Doing so, the negative effects of nanomaterials must not be overlooked, such as toxicity generated by free radicals leading to lipid peroxidation and DNA damage. Under this scenario, there is a need to predict the environmental effect of these nanoparticles in the foreseeable future. Key focus of the discussion will particularly relate the nanoparticles as adjuvant for agricultural crops, which may be toxic to plants and microbes naturally present in soil and generation of nanowaste in agroecosystem.
