Given a label rate of 3 pounds per acre and a spray rate of 10 gallons per acre, how many pounds of product are needed per gallon of spray mixture?

Given a label rate of 3 pounds per acre and a spray rate of 10 gallons per acre, how many pounds of product are needed per gallon of spray mixture?

• A. 0.1 lb/gal
• B. 0.2 lb/gal
• C. 0.3 lb/gal
• D. 0.4 lb/gal

Answer: (C)

Dividing the rate per area by the spray volume per area converts a per-acre rate into a per-gallon rate. With 3 pounds per acre and 10 gallons per acre, 3 lb/acre ÷ 10 gal/acre = 0.3 lb/gal. So, each gallon of spray mixture should contain 0.3 pounds of product to achieve the label rate per acre. This keeps the application consistent with the label and ensures the correct amount is delivered based on how much spray is applied. If the spray volume per acre were different, the pounds per gallon would change accordingly (e.g., more gallons per acre means fewer pounds per gallon).
