A spraying device for deploying liquids for agricultural purposes. The spraying device includes at least one spray nozzle for spraying the liquid and at least one mixing device, which includes at least one mixing chamber, at least one first inflow for a carrier liquid, at least two second inflows for different active agent liquids, and at least one outflow connected to the spray nozzle, connecting to the mixing chamber. It is provided that an actuatable valve is associated with each of the inflows. A device is also provided which actuates the valves during intended use in such a way that a constant volume flow results in the outflow regardless of the actuation of the valves/switching of the inflows.
