ABSTRACT:
A sprayer has a sprayer outlet and a pressurizable reservoir adapted to contain a fluid. The reservoir has an air-pressure outlet and a reservoir outlet, the reservoir outlet being in fluid connection with the sprayer outlet. Detachable, pressurizable tanks are adapted to contain a chemical, each tank having a chemical outlet and an air-pressure inlet. Each air-pressure inlet is in fluid connection with the air-pressure outlet of the reservoir for equalizing air pressure between the reservoir and each tank. A switch is adjustable between a plurality of settings for causing at least one of the chemical outlets to be in fluid connection with the sprayer outlet. A ratio valve is provided for selecting a fluid flow rate out of the selected outlet. Fluids flowing into the sprayer outlet from the outlets are mixed together prior to discharge from the sprayer outlet.
