Which statement best aligns with maintaining long-term pesticide effectiveness?

• A. Rotate pesticides to prevent resistance
• B. Use the same pesticide repeatedly
• C. Increase the dose indiscriminately
• D. Ignore resistance concerns

Answer: (A)

Pesticide resistance management is the goal here: to keep chemicals working over time by limiting how quickly pests adapt. Using the same pesticide repeatedly creates strong selection pressure for resistant individuals, so the survivors pass their resistance to the next generation and effectiveness drops. Rotating pesticides with different modes of action spreads that selection pressure across different pest biology, making it harder for the population to become resistant to all products. This delay in resistance helps maintain control longer. Increasing the dose indiscriminately can harm beneficial organisms and the environment and still selects for resistance, while ignoring resistance concerns speeds up loss of effectiveness. So rotating pesticides to prevent resistance best supports long-term pesticide performance.
