What is the process of determining whether an insecticide application was successful called?

• A. Evaluation
• B. Calibration
• C. Inspection
• D. Verification

Answer: (A)

Evaluating post-application outcomes is about assessing whether the insecticide achieved the intended control. After an application, you measure pest levels or damage and compare them to the goals you set before treatment. If the pest population is reduced as expected or damage falls below an acceptable threshold, the treatment is considered successful; if not, you analyze factors like timing, coverage, resistance, or environmental conditions and decide on next steps. This focus on measuring outcomes against objectives is what makes evaluation the right term.

Calibration isn’t about judging effectiveness—it’s about setting equipment to apply the correct amount. Inspection refers to checking equipment, conditions, or procedures, not the actual results of pest control. Verification involves confirming that procedures or records meet requirements, not whether pest control goals were reached.
