Calibration is the practice of

• A. Estimating pest density
• B. Verifying and adjusting equipment to apply a predetermined amount per area
• C. Measuring pesticide residues in soil
• D. Determining economic injury level

Answer: (B)

Calibration is about making sure your spray equipment delivers the exact amount of pesticide for each unit of area as specified on the label. It involves measuring the actual output from your nozzles at the speed you’ll travel, then adjusting flow, nozzle sizes, pressure, or your pace until the target rate (for example gallons per acre) is achieved. This practice ensures uniform coverage, prevents under- or over-application, maximizes effectiveness, and protects crops, workers, and the environment while staying compliant with label requirements. The other ideas—estimating pest density, measuring residues in soil, or determining an economic injury level—are separate tasks: scouting, residue analysis, and decision thresholds, not calibration.
