Which statement best describes why pesticide rotation is recommended?

• A. Rotation helps prevent resistance by varying modes of action
• B. Rotation is optional and rarely effective in pest control
• C. Rotation guarantees zero pests
• D. Rotation eliminates the need for monitoring

Answer: (B)

Pesticide rotation is recommended to manage resistance by changing the mode of action used against pests over time. By rotating products that attack pests in different ways, you prevent any one pest population from being continually exposed to the same target. This makes it harder for pests to develop resistance, because individuals that survive one mode of action are less likely to survive against another. Rotation helps keep chemical tools effective longer and supports a more reliable level of control when used alongside monitoring and other integrated pest management practices. It does not guarantee zero pests, and it doesn’t replace the need to monitor pest levels and adjust tactics accordingly.
