The process of measuring and adjusting the amount of pesticide a piece of equipment applies to a target is called what?

• A. Calibration
• B. Registration
• C. Evaluation
• D. Monitoring

Answer: (A)

Calibrating is the process of measuring how much pesticide your application equipment actually delivers and adjusting it to meet the target rate from the label. You set a desired rate (like gallons per acre) and test the sprayer over a known area, using catch cups or a flow meter to determine the actual output. If the measured rate is off, you fine-tune by changing nozzle type or size, adjusting the spray pressure, or altering travel speed until the output matches the intended rate. This ensures uniform coverage, correct active ingredient amounts, and compliance with label directions, while reducing waste and minimizing drift or environmental impact.
