Which sequence best outlines integrated pest management (IPM) for a home garden?

• A. Identify the pest and damage; monitor and assess population levels; determine economic thresholds; implement the least-toxic effective management method; monitor and evaluate results
• B. Apply pesticides, monitor pests, identify damage, evaluate results, select controls
• C. Use only chemical controls, then observe results
• D. Identify the pest and damage, monitor and assess population levels, determine economic thresholds, choose the least-toxic effective management method, implement, and evaluate results

Answer: (D)

Integrated pest management in a home garden is a stepwise, decision-based approach that starts with correctly identifying the pest and the damage it’s causing. Next, you monitor and assess population levels over time to understand the pest pressure you’re dealing with. Then you determine the economic threshold—the pest density at which the expected damage justifies taking action. After that, you choose the least-toxic method that will actually be effective, aiming to minimize harm to people, beneficial insects, and the environment. You implement the control and then continue to monitor and evaluate the results to see if the action worked and to adjust if needed. This sequence ensures actions are based on accurate information, justified by potential damage, and aligned with safety and sustainability principles.
