How much Q4 Plus Turf Herbicide you use per 4 gallon tank will depend on what size area you cover with 4 gallons (i.e. 4,000 sq ft, 500 sq ft) as well as what kind of turfgrass you are treating. You may also view the full application rates on the product label here.
Keep in mind that Q4 Plus is not safe to use on many warm season grasses such as St. Augustine and Centipede.
