According to the Monterey 70% Neem Oil RTS Product Label, each pint size bottle should cover roughly 2500 sq/ft of area and a 32 oz container would cover roughly 5000 sq/ft. That comes out to roughly 6.4 oz per 1000 sq/ft and it will likely disperse several ounces per gallon of water that runs through the hose attachment. If you have any other questions about the device on the bottle we would recommend you contact the manufacturer directly at (559) 499-2100.
