Which control methods are commonly included in IPM?

• A. Only chemical controls
• B. Cultural, mechanical, biological, and chemical controls
• C. Biological controls only
• D. Mechanical controls only

Answer: (B)

Integrated Pest Management relies on using a mix of strategies together, not just one. In practice this means combining cultural, mechanical, biological, and chemical controls to manage pests. Cultural controls involve practices that reduce pest establishment and spread, like crop rotation, sanitation, selecting resistant varieties, proper spacing, and good timing. Mechanical controls are physical actions or devices that prevent or remove pests, such as hand-pulling weeds, traps, row covers, or barriers. Biological controls use natural enemies or biological agents to suppress pests, including predators, parasitoids, and microbial products. Chemical controls are pesticides used judiciously, chosen and applied in ways that minimize harm to non-target organisms and the environment, often as a last resort or part of an overall plan with monitoring and thresholds. Seeing IPM as an integration of these tools helps explain why this approach is preferred: it reduces pest pressure with a combination of methods, lowers the risk of resistance, and minimizes environmental impacts compared to relying on a single method. Relying only on chemicals, or only on one other method, does not reflect the multi-tool, preventative, and monitoring-oriented nature of IPM.
