Abstract: In this paper our work was to study the application and the uses of unmanned aerial vechicle insecticide spraying. Indian agriculture needed production and protection materials to achieve high productivity. Indian farmers are not rich to buy costly equipment for spraying pesticides or insecticides in their farm. Use of pesticides plays important role in agricultural fields for a better crop yielding. A quadcopter, also called a quad rotor helicopter or quad rotor, is a multirotor helicopter that is lifted and propelled by four rotors. Quadcopters are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by a set of rotors (vertically oriented propellers). The paper proposes a new strategy to replace humans in various agricultural operations like detection of presence of pests, spraying of pesticides, spraying of fertilizers, etc.Quadcopter Drone is working principle on aviation, It means airborne, airplane, etc.This research focused on develops a remotely operated Quadcopter system. . The paper proposes a new strategy to replace humans in various agricultural operations like detection of presence of pests, spraying of pesticides, spraying of fertilizers, etc.The Quadcopter is controlled through Graphical User Interface (GUI). Communication between GUI and Quadcopter is done by using wireless communication system. The Quadcopter balancing condition is sensed by KK2 multi controller. For smooth landing, Quadcopter is equipped with ultrasonic sensor.All Signals from sensors are processed by KK2 Circuit board.The experiment shows that Quadcopter can hover with maintain it balancing and stability. Quadcopter can accept load disturbance up to 250g during it Hover condition. Maximum operated time of Quadcopter is six minutes using 3200mAh Lipo battery and operate time can be increase by using largest battery Capacity. This project is to mainly overcome the ill-effects of pesticides on human beings.
