Which practice does not align with delaying resistance?

• A. Rotating pesticides to prevent resistance
• B. Using products with different modes of action over time
• C. Monitoring pest populations
• D. Reapplying the same pesticide repeatedly

Answer: (D)

Delaying resistance relies on reducing the consistent pressure that favors pests with resistance traits. Rotating pesticides to use different modes of action over time helps prevent any one resistance mechanism from taking over, and monitoring pest populations allows you to catch changes in susceptibility early and adjust strategies before resistance spreads. Reapplying the same pesticide repeatedly keeps selecting for the same resistance trait every time, giving resistant individuals a steady advantage and accelerating the loss of control. So the practice that reuses the same chemical over and over is the one that does not align with delaying resistance.
