(1) Calibrate sprayer for gallonage output of spray per unit time or unit area and convert to gallons per acre (1 acre = 43,560 square feet). Amounts per gallon, for other gallonages than those shown, can be easily calculated using the 10 gallon per acre as a base, i.e., to mix a spray for 35 gallons per acre of a formulation having 3 pounds active per gallon, use 126.18 divided by 3.5 = 36 ml of formulation per gallon of spray; or to mix a spray for 7 gallons per acre from the same formulation, use 126.18 divided by 0.7 = 180 ml of formulation per gallon of spray.
