Abstract: A sprayer control system and method for using same includes a pump for directing a mixture of chemical and fluid carrier to a flow control valve. The flow control valve includes an intake port, a bypass port, and a regulated outlet port. A valve member is rotatable to direct fluid from the intake port either to the bypass port or the regulated output port. Fluid from the bypass port is sent through a bypass line back to the intake opening of the fluid pump. Various chemical tanks are connected to the bypass line for injecting metered amounts of chemical into the bypass line.

Abstract: The chemical tank of the present invention comprises a plastic container having a plurality of walls including a top wall, side walls, and an inclined bottom wall. The lower end of the inclined bottom wall includes a low point for receiving the last portions of the chemical. A suction tube is mounted within the container and extends downwardly where its lower end is adjacent the low point of the container. A heel bracket is used to mount the container to a spray wagon in such a manner that the container is oriented so the chemical will drain downwardly to the lower point of the container. The container can be quickly and easily attached and detached from the spray wagon.
