Which method does IPM combine for effective pest control?

Integrated Pest Management (IPM) is a holistic approach that combines several pest control tactics to manage pest populations in an environmentally sensitive and effective manner. This approach involves the integration of various strategies, which can include biological control methods (such as the use of natural predators), cultural practices (like crop rotation), physical controls (such as traps), and the judicious use of chemical treatments when necessary.

By utilizing multiple tactics, IPM aims to reduce reliance on any single method, minimizing the risk of pesticide resistance and environmental impact. It emphasizes monitoring pest populations and making informed decisions based on the specific context and severity of the pest issue. This comprehensive strategy is key to sustainable pest management and is why the correct answer emphasizes the combination of several pest control tactics.
