What is a key recommendation to reduce pest resistance?

Using the same pesticide repeatedly
Only using chemical controls
Employing varying modes of action and other control methods
Applying pesticides during peak pest seasons

The correct answer is: Employing varying modes of action and other control methods

Employing varying modes of action and other control methods is essential in reducing pest resistance because it disrupts the pests' ability to adapt to a specific pesticide. When a single pesticide is used repeatedly, especially if it operates through the same mechanism of action, it creates selection pressure on the pest population. Over time, pests that are susceptible to that pesticide are eliminated, while those with some level of resistance survive and reproduce. By using a variety of modes of action—different chemicals that target various physiological processes in pests—along with integrating non-chemical control strategies like biological control, cultural practices, and mechanical methods, it becomes more challenging for pests to develop resistance. This diverse approach not only helps in prolonging the effectiveness of the pesticides but also promotes sustainable pest management practices.
