ABSTRACT:
A relatively small sprayer for liquid fertilizers, weed killers, herbicides or the like is mounted on a small frame and is attachable to a three-point hitch of a tractor or may be pulled by hand. A tank is mounted on the frame and a ground engaging roller is journalled transversely across the rear of the frame. An open based enclosure encloses the roller and shields the spray nozzle boom which extends transversely adjacent the front of the enclosure. The nozzles spray the liquid downwardly and rearwardly so that it strikes the plants on the front and top side thereof. It also maintains the roller in a wet condition so that the roller engages the rear of the plants as it passes over same thus ensuring a complete treatment of the vegetation. Flexible skirts extend downwardly from the front and side edges of the enclosure to prevent any spray escaping from around the perimeter of the enclosure.
