What is a common consequence of over-reliance on chemical pesticides?

Over-reliance on chemical pesticides commonly leads to increased resistance in pest populations and potential loss of efficacy. When a specific pesticide is used repeatedly, pests can develop survival strategies or genetic mutations that make them less susceptible to the chemical. This resistance can escalate over time, resulting in a scenario where pests no longer respond to the treatment that was once effective, necessitating the use of higher doses or different, potentially more toxic chemicals to manage the pest population.

This phenomenon poses significant challenges for pest management, as it can lead to a cycle of increased pesticide use, higher costs, and greater environmental impact. Integrated Pest Management (IPM) practices encourage a diversified approach to pest control, incorporating biological, cultural, and mechanical methods alongside chemical applications to minimize resistance development and maintain pest control effectiveness.
