Effective delivery of agricultural chemicals is accomplished by the utilization of nanopesticides, which are distinguished by their nanostructures that range from 1 to 200 nanometers. In comparison to conventional insecticides, nanoparticles that contain active ingredients have a number of beneficial characteristics. There is, however, a new category of environmental contaminants that have emerged as a result of the rapid development of nanoparticles that are specialized for the purpose of pest management. A discussion of the negative effects that pesticide exposure has on both the environment and human health is included in this present article, which also examines the history of nanopesticides. In addition to this, it investigates the possible advantages of nanoparticles in terms of increasing agricultural output and issues regarding the environment. According to existing literature, there exist many approaches for achieving controlled dispersal and stimuli-responsive systems that can distribute agricultural chemicals and genetic material in a slow and targeted manner on a specific target. The study places an emphasis on the numerous sources of nanoparticles, the environmental consequences that they have in crop habitats, and the recent advancements in nanopesticides research that are based on the findings of experiments. Furthermore, this chapter covers concerns relating to the development, formulation, and toxicity of pesticide products within the framework of environmentally conscious and sustainable farming practices.
