There are far too many advances in precision agriculture for improving crop production in today's world. Over 70% of rural populations in developing nations such as India rely on agricultural areas. Diseases have caused significant losses in agricultural areas. These diseases are caused by pests and insets, and they decrease crop yield. In order to improve crop quality, pesticides and fertilizers are used to kill insects and pests. WHO (World Health Organization) when spraying pesticides in the crop field manually, the organization projected that one million instances of illness occurred. The Vacant Position Aerial vehicle (UAV) - planes are used to spray insecticides to prevent human health concerns while spraying by hand. Where equipment and manpower are difficult to operate, UAVs may be utilized effortlessly. This article provides a short overview of the program's implementation. Crop monitoring and pesticide application using unmanned aerial vehicles (UAVs).
