The book discusses nanomaterial interactions with plants and their potential benefits for agriculture. It stands as an authoritative resource for a broad community, describing how Nano formulations of various types of agrochemicals in agriculture are rapidly expanding among the scientific and non-scientific community. The purpose of this book is to provide comprehensive information about the development of synthesis and scaling-up, future scope, current challenges, potential risks assessment and the legal requirements for regulating nanomaterial-based agrochemicals for agricultural sustainability. The book includes the application of Nano chemicals as Nano primers for seed germination, Nano fertilizers to increase crop yields, Nano pesticides for insect pest management, Nano fungicides, Nano herbicides, Nano nutrient, and Nano sensors for tracking crop and soil health conditions, including detecting agrochemicals. In addition, the authors discuss Nano enabled agrochemicals in relation to their toxicological implications in agroecosystems, as well as risk assessment and registration policies for ensuring the safety of nanomaterials used in farming.
