A spray device includes a valve assembly, in inlet pipe, an extension tube, and a spray tip. The valve assembly includes an inlet, an outlet, and a seal between the inlet and the outlet. A force applied to an actuator pivotably connected to the valve assembly forces the seal away from a sealing position, and allows a pressurized fluid to move from the inlet to the outlet. The fluid exits the outlet, and enters a passage in the extension tube. The spray tip includes a substantially vertical slot that communicates with a passage. The passage of the extension tube further communicates with the passage of the spray tip, thereby forcing the fluid to exit the slot in a wide uniform spray. A second embodiment provides an extension tube including a bend for delivery of the pressurized fluid closer to a ground surface.
