Abstract: A system for applying a liquid chemical mixture to an area. The system comprises: a liquid conduit for supplying a flow of pressurized liquid to the system, which pressurized liquid enters the conduit through an inlet valve; a container for a liquid chemical composition, which container is in fluid communication with the conduit so that the composition contacts the pressurized liquid in the conduit to form the mixture; a reservoir in fluid communication with the conduit, which reservoir is configured to receive and store the mixture, at least one spray nozzle, through which spray nozzle, the mixture is dispensed to the area; a pump in fluid communication with the reservoir and with the spray nozzle, which pump forces the mixture through the spray nozzle; and an automated controller which is configured to at least (i) control operation of the inlet valve and (ii) control operation of the pump. Methods for dispensing a liquid chemical mixture to an area are also described.
