Which of the following is NOT a benefit of pest monitoring?

• A. Observing seasonal changes in pest populations
• B. Proper timing of pesticide applications
• C. Assessing the effectiveness of pest control measures
• D. Reducing crop yield by delaying harvest

Answer: (D)

Pest monitoring is about tracking pest populations over time so you can act when it matters. By watching how pest numbers change with the seasons, you can anticipate when pressure will be highest and plan actions accordingly. It also helps you time pesticide applications so they are effective and economical, and it provides feedback on whether your control measures are working, allowing you to adjust as needed to protect yield and quality. Delaying harvest to wait for pest levels to drop is not a benefit of monitoring; delaying harvest generally reduces yield and can hurt quality and market value, defeating the purpose of monitoring, which is to prevent losses and protect the crop.
