Ultra Dawn was mixed at a rate of 4 oz/1 gallon water, and then drenched onto circular areas 10 inches in diameter at three different application volumes: 40, 80 and 160 gallons per 1000 sq ft. Note that efficacy was best at the higher applications volumes (80 and 160 ga/1000 sq ft). See this research report for more detail.
