What is the sustainable approach that reduces pests to a tolerable level using cultural, physical, biological, and chemical methods?

The sustainable approach that reduces pests to a tolerable level using a combination of cultural, physical, biological, and chemical methods is Integrated Pest Management (IPM). IPM is a comprehensive strategy that emphasizes understanding the pest life cycles and their interactions with the environment, allowing for targeted interventions.

Cultural methods can include crop rotation or changing planting times to disrupt pest life cycles. Physical methods might involve barriers or traps to prevent pest access. Biological methods use natural predators and parasites to control pest populations, while chemical methods utilize pesticides as a last resort, focusing on minimal application to achieve effectiveness while considering environmental and human safety.

This integrated approach ensures that pest management is not solely reliant on chemicals, promoting long-term sustainability and reducing the risk of developing pest resistance.
