What best defines Integrated Pest Management (IPM)?

• A. A single-method pesticide program
• B. Annual pesticide rotation
• C. A holistic, ecosystem-based approach combining multiple strategies
• D. Biological control alone

Answer: (C)

Integrated Pest Management focuses on treating pests with a mix of methods that fit the crop system and environment, guided by regular monitoring and action thresholds. It aims to manage pests in the least risky way by combining cultural, mechanical, biological, and, when needed, chemical controls in a coordinated plan, rather than relying on one tool. This holistic, ecosystem-based approach reduces economic damage while protecting people, beneficial organisms, and the environment. A single-method pesticide program centers on one tool and doesn’t capture the broad, integrated strategy. Annual pesticide rotation describes how pesticides might be used over time but doesn’t address the full system of monitoring, thresholds, and multiple control methods. Using biological control alone omits other important components like sanitation, resistant varieties, and habitat management. In practice, IPM starts with correct pest identification and ongoing monitoring, sets action thresholds, and then selects the least disruptive, most effective combination of strategies to keep pest levels under economic damage.
