Mixing of liquid or dry product should be in accordance to manufacturers labels. Remember this is designed for low volume spraying so the mix will be more concentrated

Remember that your machine is factory set to put down 1/3 gallon of liquid per 1,000 sq.(at 5MPH and 40PSI ).
For instance, some products call for 1.1 to 1.5 oz per 1,000 sq. We would recommend using 1.3 (median value of 1.1 to 1.5). Since you are using a 1/3 gallon, you need to multiply by 3, then multiply that amount by the number of gallons your put in your tank 1.3 (median value of 1.1 to 1.5) X 3 (1.3 gallon) X gallons of water needed.
If you were filling a 30 gallon tank your equation would look like this: 1.3 X 3 X 30 = 117 ounces in 30 gallons of water.
