Which approach is NOT beneficial for managing pesticide resistance?

The consistent use of the same pesticide is not beneficial for managing pesticide resistance because it can lead to the development of resistant pest populations. When a specific pesticide is applied repeatedly, pest species that are naturally resistant to that chemical survive and reproduce, passing their resistance traits to the next generation. This selective pressure reinforces resistance, making the pesticide less effective over time.

In contrast, the other approaches help mitigate resistance. Strategic application of various pesticide types can disrupt resistance development by alternating modes of action, while regular monitoring of pest populations allows for timely interventions and adjustments to management strategies. Integrated pest management practices incorporate a variety of methods, including cultural, biological, and chemical tactics, to manage pest pressures effectively and sustainably, thus minimizing the risk of resistance. By diversifying control methods, the likelihood of pests developing resistance is significantly reduced.
