What are the fundamental steps of Integrated Pest Management (IPM)?

• A. Monitoring, accurate identification, economic thresholds, and selective control using biological, cultural, and chemical methods while minimizing environmental impact
• B. Spraying pesticides before detection
• C. Eliminating all pests using chemical controls
• D. Ignoring pest thresholds, acting after damage occurs

Answer: (A)

Integrated Pest Management relies on a proactive, evidence-based process: we start with regular monitoring to know what pests are present and in what numbers, and we identify them accurately to avoid misidentifying beneficial organisms as pests. Next, we use economic or action thresholds to decide if intervention is warranted—only when pest levels are likely to cause economic damage do we take action. When we do intervene, we use a mix of control methods (biological, cultural, and sometimes chemical) chosen to be effective while minimizing environmental impact and delaying or preventing pest resistance.

Monitoring keeps you informed about pest trends and helps catch problems early. Accurate identification ensures you target the right pest and choose the most appropriate control. Thresholds prevent unnecessary actions and reduce costs and environmental harm by signaling when control will provide a net benefit. The control methods are applied in a way that favors least-harmful options first and uses chemicals judiciously, often in rotation and as a last resort.

The other options skip essential IPM steps: spraying before detection is reactionary and wasteful, eliminating all pests with chemicals ignores environmental consequences and resistance, and acting after damage occurs without thresholds wastes opportunities to prevent losses.
