Pest monitoring helps determine when to apply control measures.

• A. True
• B. False
• C. Not sure
• D. Always

Answer: (A)

Monitoring pests provides the data you need to decide when to treat. By regularly scouting, counting pests, and using established action thresholds, you determine whether pest levels justify control. This timing is crucial because applying a pesticide at the right moment—often when pests are most vulnerable or before damage becomes severe—improves effectiveness and reduces unnecessary applications. It also helps protect beneficial organisms, lowers costs, and helps prevent resistance. If monitoring shows numbers are below the threshold, you hold off; when they exceed the threshold, you apply in the most appropriate window. So the statement is true.
