ABSTRACT:
An improved apparatus for spraying chemicals from a vehicle. Chemical concentrates from a separate supply tank are injected at a rate proportionate to the vehicle's land travel speed into water which is dispensed at a constant rate. A water pressure activated control means prevents injection of the chemical concentrate into the water line when the water pressure is not within the predetermined range which will assure nozzle spray pattern.
