Specifically, how do I calculate what setting to use (3,6,15,21 gallon)
On Bermudagrass, you will use 3.2 oz of Bio Advanced Season Long Weed Control for Lawn Concentrate in 2 gallons of water to treat 500 square feet. So for 7,500 sq ft, you would use 24 oz in at least 30 gallons of water. Since the Chapin 6005 sprayer only has a highest dial setting of 21 gallons, we recommend you treat half the yard at a time. To do this, put 12 oz of the herbicide concentrate into the sprayer reservoir, then add water in reservoir with water up to the red “15” line on the right side of the measurements. You will then set the top dial to the 15 gallon setting (15/57) and spray half the lawn evenly using this mixture. Repeat these steps for the other half of the lawn.
