Is it required by law that pesticide application equipment be calibrated?

• A. True
• B. False
• C. Sometimes
• D. Not at all.

Answer: (A)

Calibrating pesticide application equipment is required by law because the rules mandate that the product be applied at the labeled rate. Calibration translates that label rate into the actual spray output you deliver under real field conditions, taking into account nozzle type, pressure, and your speed. This ensures the amount applied per area is accurate, protecting people, non-target organisms, and the environment while also ensuring the pesticide works as intended. If you can’t demonstrate a calibrated setup, you can’t prove you’re applying at the legal rate, which can lead to regulatory violations and liability. For these reasons, calibration is treated as a legal compliance step in pesticide practice.
