What is the third basic step of IPM?

• A. Detection
• B. Evaluation
• C. Economic, Functional, or Aesthetic Significance
• D. Method Selection

Answer: (C)

In IPM, you first consider whether a pest problem actually warrants action by judging how significant the pest is. The third step is to evaluate its significance in practical terms—economic impact, functional disruption, or aesthetic damage. This assessment answers whether the problem justifies intervention and helps set the level of control needed. By focusing on significance, you avoid unnecessary actions for minor issues and direct effort where it will make a real difference.

Detection happens earlier as you observe and identify pests, and method selection comes after you’ve determined significance, so you choose controls that fit the level of threat and the specific pest.
