Which statement about pesticide rotation is true?

• A. Rotating pesticides is an effective way to slow resistance
• B. Rotating pesticides increases pest resistance
• C. Rotating pesticides has no effect on resistance
• D. Rotating pesticides guarantees complete pest elimination

Answer: (A)

Rotating pesticides helps manage resistance by changing the way pests are attacked across different generations. When the same pesticide is used repeatedly, pests that carry resistance traits survive and reproduce, gradually making that chemical ineffective. Introducing pesticides with different modes of action interrupts that consistent selection pressure, making it harder for resistance traits to spread through the population and slowing the evolution of resistance. This approach keeps pesticides effective longer and is a key part of resistance management in greenhouseIntegrated Pest Management. It’s not a guarantee of complete pest elimination, and rotations should be planned with awareness of cross-resistance and in combination with monitoring and other control practices.
