The Q4 Plus Herbicide Product Label states: Broadcast Treatments for Cool Season Turfgrass (kentucky bluegrass, perennial ryegrass, fescues, annual bluegrass, rough bluegrass, annual ryegrass)- Use rate per Application is 7 to 8 pints per acre or 2.6 to 3.0 fl oz/1000 sq/ft. When broadcasting your water volume may change so while the concentration of product per area is the same as the spot treatment, if your turf is very dense you may need 2-4 gallons of water over 1000 sq/ft, vs the only 1 gallon needed for spot treatments.
