Nano enabled plant protectant is an advancement approach to deal with the difficulties of dosedependent toxicity, solubility, degradation, leaching and health issues of conventional pesticides. The main idea behind incorporation of nanoformulation is their controlled delivery and release to prevent premature degradation of active ingredient under the influence of changing environment conditions. Nanocarriers (nanocapsules, nanospheres, micelles, nanogels, nanoemulsions, nanodispersion and inorganic material) alters the properties of active ingredients and provide controlled release kinetics with, better dissolvability, low dose, enhanced stability and long lasting pest-control efficiency. This review critically assesses the incredible potential of various nanocarriers, their methods of preparation and biological effectiveness. It additionally features the potential and issues with nanoformulations of botanical insecticides and essential oils. The study also accounts performances of nano-enabled products, their challenges with respect to field application and assessment of new environmental risks.
