Combining various management practices is essential for effectively reducing the chances of pest resistance. This approach, often referred to as integrated pest management (IPM), brings together a range of strategies, including cultural, biological, and chemical methods. By using a variety of practices, such as altering planting times, using resistant crop varieties, and applying different classes of pesticides, pests are less likely to develop resistance to any one control method. This strategy disrupts the life cycles of pests and can lead to more sustainable and long-term management of pest populations.

In contrast, relying solely on similar chemical structures or applying pesticides at maximum rates can lead to increased pest resistance due to the selective pressure they impose on pest populations. Furthermore, rotating crops without considering the pest history may not effectively disrupt pest populations, as pests can still thrive if suitable conditions exist. Therefore, employing a combination of diverse management strategies is the most effective way to combat pest resistance.
