The present utility model relates to a joystick that allows manual control of its basic functions for safe and correct operation (to the operator and the environment) of motorized backpack sprayers—equipment used for spraying/atomizing liquids for pest and disease control in agriculture, as well as for vectors of endemic diseases in public health. The joystick basically consists of a body (1), which has a lower end adapted to couple an air discharge pipe (9) of the motorized backpack sprayer, a spike of fluid inlet (3) to couple a hose connected to the reservoir of chemicals, and a spike of fluid outlet (2) with the purpose of coupling a hose connected to the atomizer nozzle.
