(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.
