Why is resistance in pests a significant concern for pesticide application?

Resistance in pests is a significant concern for pesticide application because it directly affects the effectiveness of pest control strategies. When pests develop resistance to certain pesticides, they are able to survive and reproduce despite previous applications that were once effective at controlling their populations. This survival can lead to a situation where the pesticide no longer manages the pest population effectively, resulting in greater challenges for farmers and pest managers. Consequently, the effectiveness of pest management diminishes, leading to potential economic losses and an increased need for higher doses or more frequent applications of pesticides, which can further escalate the issue of resistance over time. Addressing pest resistance is crucial for maintaining effective pest management practices and ensuring sustainable agricultural production.
