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.
