What term describes checking whether a pesticide application achieved the intended effect?

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

Answer: (A)

Evaluating whether a pesticide application achieved the intended effect focuses on judging the actual outcome after treatment. It means looking at what happened—did pest levels drop, crop damage lessen, or disease incidence meet the target—and comparing that result to the goal set before spraying. This post-treatment judgment helps decide if the current approach worked and what to adjust next time.

Calibration is about getting the equipment to deliver the correct amount of product, not about the outcome itself. Verification checks that procedures and parameters were followed, such as applying at the right rate or using the right timing, but it doesn’t measure whether the pest control goal was reached. Assessment is a broader appraisal of performance or impact, which can include multiple factors beyond just the direct effect on pests. The question asks specifically about checking the actual achieved effect, which is best described as evaluation.
