In this process, GPA is defined as what?

• A. Total gallons sprayed divided by the test strip acreage.
• B. Gallons sprayed in the strip divided by the test strip acreage.
• C. GPA equals gallons sprayed per acre.
• D. Gallons sprayed in the strip times the test strip acreage.

Answer: (B)

GPA is about the application rate—how many gallons are applied per acre on the calibration test strip. To get that rate, you take the gallons sprayed inside the test strip and divide by the strip’s acreage. This yields gallons per acre, the standard way to express how much product would be applied over one acre under calibration conditions. Using the total gallons sprayed for the whole area would not reflect the per-acre rate, and multiplying instead of dividing wouldn’t give a rate. So the definition is the gallons sprayed in the strip divided by the test strip acreage.
