What is the most important principle of IPM?

• A. Eradication
• B. Immediate chemical use
• C. Waiting for infestation
• D. Prevention

Answer: (D)

Prevention sits at the foundation of Integrated Pest Management. By stopping pests from entering, establishing, or thriving in the greenhouse, you reduce damage and make any later controls smaller, more targeted, and less disruptive to beneficial organisms. Prevention actions include sealing entry points and using screens, keeping the facility clean and free of crop residues that harbor pests, managing humidity and air flow to discourage pest reproduction, and choosing resistant varieties or using good sanitation and crop rotation to interrupt life cycles. When pest pressure is kept low through prevention, monitoring and thresholds can guide only necessary, targeted actions, often with biological controls or minimal chemical inputs. Reacting by eradicating pests, spraying immediately, or waiting for an infestation runs counter to IPM because it increases chemical use, disrupts beneficials, and allows problems to escalate. So prevention is the best and most important principle because it reduces the need for interventions and supports a balanced, sustainable approach.
