ABSTRACT:
A method of applying a chemical material, such as a pesticide, to a surface utilizes a wheel mounted spraying assembly. The wheel mounted spraying assembly includes: a rod having a wheel rotatably mounted on its lower end portion for supporting the spraying assembly on a generally horizontal surface and enabling the spraying assembly to be moved over the surface; a spray nozzle mounted on the spraying assembly adjacent the wheel; a supply line for supplying a chemical material under pressure to the spray nozzle; and a control for controlling the flow of the chemical material to and through the spray nozzle. The spray nozzle is oriented to spray the chemical material in an expanding pattern in an outward direction to one side of the lower portion of the spraying assembly to apply the chemical material to a generally vertical and/or generally horizontal surface.
