Why is it important to rotate the use of pesticides with different modes of action?

• A. To prevent negative environmental effects
• B. To increase the cost of pesticide usage
• C. To prevent the development of resistance among pest populations
• D. To maintain continuous pest presence

Answer: (C)

Rotating the use of pesticides with different modes of action is crucial because it helps prevent the development of resistance among pest populations. When pests are repeatedly exposed to the same pesticide or those with similar action modes, they can adapt over time, leading to a situation where the pesticide becomes ineffective against them. This resistance can significantly reduce the efficacy of pest management strategies, making it more difficult to control pest populations. By using pesticides with different modes of action, it disrupts the pests' adaptation mechanisms. This strategy helps maintain a reliable level of pest control, reducing the likelihood of resistance development and prolonging the effectiveness of the available pesticides. It also supports integrated pest management practices, promoting healthy ecosystems and more sustainable agricultural practices.
