What issue results from the continued use of the same pesticide?

The continued use of the same pesticide can lead to pesticide resistance in pest populations. This occurs when individual pests survive exposure to a pesticide due to genetic variations that make them less susceptible. Over time, as the pesticide is applied repeatedly, these resistant pests reproduce, leading to a population that is increasingly difficult to control with the same chemical. This cycle can create a significant challenge for farmers and pest managers, as they may need to rely on stronger chemicals or different management strategies, which can be more costly and less environmentally friendly. As resistance develops, the effectiveness of the pesticide diminishes, and pests can become more of a problem, requiring a change in pest management tactics to maintain crop health and yields.
