Q4 Plus Turf Herbicide is labeled for green, yellow, and giant foxtail. The mixing ratio of Q4 really depends on what and where you are treating. The product label suggests using 1.8-2.6 fl oz on warm season turf (cool season-2.6 - 3 oz. per 1,000 sq. ft.) per one gallon to treat 1000 sq.ft. A follow up application may be required for this weed species.
Once areas that have been treated with Q4 Plus Turf Herbicide are dry, it would be safe for animals to return.
Q4 Plus is applied at the rate of 7 - 8 pints per acre if treating weeds in cool season grasses, or 5 - 7 pints per acre for warm season grasses. If you need to treat 4 acres, you will need one gallon.
Your 2 gallon hand pump sprayer falls under the category of low volume spray equipment that the Q4 Plus Turf Herbicide label is referring to.
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.
Q4 Plus Turf Herbicide if applied to St Augustine may suppress it, but may not kill it. Roundup would be a better option to spot treat.

Q4 Plus Turf Herbicide can safely be applied to established Tall Fescue to treat for listed weeds when applied during the cooler times of the days when temps are below 80 degrees.

Q4 Plus Turf Herbicide is labeled to be safely used on tall fescue and will not control it. There is not a selective product that would remove one cool season turf such as Tall Fescue from another like Kentucky Bluegrass. We suggest spot treating with a non-selective like GlyPhoSel Pro and then reseeding after 2 weeks.
