Example 2:
You need to spray only one acre and your equipment is calibrated to spray
60 gallons per acre. The label calls for 2 pounds of formulation per 100 gal-
lons of water. How many pounds of formulation should be added to the tank
to make 60 gallons of finished spray?
Gallons in tank (60) x Ibs.
per 100 gallons (2) = 1.2 lbs. (19 oz.) in tank
100 gallons
2.
Pounds Per Acre
The label may list the recommended dosage as pounds per acre. If the job
requires a full tank, you must know how many gallons your equipment ap-
plies per acre and the spray tank capacity. Use these formulas:
Gallons in tank = Acres sprayed per tankful
Gallons applied per acre
Acres sprayed per tank x Pounds formulation per acre = Pounds formulation needed
in tank
Example: 3
Your sprayer applies 15 gallons per acre and your tank holds 400 gallons.
The label rate is 3 pounds of formulation per acre.
Gallons in tank (400) = 26.7 acres sprayed per tankful
Gallons per acre (15)
400 ÷ 15 = 26.7
Acres sprayed per tankful (26.7) x Pounds formulation per acre (3) = Pounds
needed in tank (80.1)
26.7 × 3 = 80.1
Add 80 pounds of pesticide formulation to the tank.
