What is the purpose of scouting in IPM?

• A. To Calibrate Irrigation
• B. To Monitor Pest Populations and Thresholds
• C. To Forecast Weather
• D. To Estimate Fertilizer Needs

Answer: (B)

In IPM, scouting means regularly checking crops to see what pests are present, how many there are, and where they are feeding. This information is then compared to economic thresholds—budgets for pest damage that justify control costs—to decide if and when action is needed. Scouting lets you detect problems early, identify the pest species and their life stages, and track how pest populations change over time, so decisions are based on actual pest pressure rather than guesses. If numbers stay below thresholds, you avoid unnecessary sprays and protect beneficial insects; if they exceed thresholds, you can target control measures at the right time to minimize damage and maximize effectiveness. The other tasks—calibrating irrigation, forecasting weather, or estimating fertilizer needs—address water, climate, or nutrition, not pest pressure and management decisions.
