PURPOSE: A spray control device of a snow-removing agent sprayer is provided to efficiently regulate the amount of solid and liquid snow-removing agent sprayed and allow additional manual operation by a user. CONSTITUTION: A spray control device of a snow-removing agent sprayer comprises a controller(30), a solenoid valve(42) which supplies hydraulic pressure to a conveyor, a spreader, and three driving units according to control signals from the controller, a first connection path(420) which delivers hydraulic pressure from the solenoid valve simultaneously to the three driving units, and a second connection path(422) which delivers hydraulic pressure to one of the three driving units, separately from the first connection path.
