Which of the following practices helps prevent pesticide resistance?

Rotating pesticides is a beneficial practice that helps prevent pesticide resistance. When the same pesticide is used repeatedly, pests can develop resistance, making the pesticide less effective over time. By rotating different classes of pesticides that have varying modes of action, the chances of resistance developing are significantly reduced. This is because rotating products can target pests in different ways, ensuring that they do not become accustomed to a single chemical or mode of action.

This strategy not only helps preserve the efficacy of existing pesticides but also supports sustainable pest management over the long term. Encouraging diversity in pesticide usage can lead to more effective pest control and decrease reliance on a limited number of chemical options, ultimately benefiting agriculture and the environment.

Other options, such as using the same pesticide repeatedly, ignoring label instructions, or applying larger doses, can contribute to resistance or negative outcomes in pest management, demonstrating why they are not effective strategies in preventing pesticide resistance.
