Which of the following is one of the strategies that can be employed in IPM?

1. Biological control

2. Restricting pesticide use

3. Planting only resistant crops

4. Using pesticides exclusively

The correct answer is: Biological control

Biological control is a foundational strategy in Integrated Pest Management (IPM) that involves using natural predators, parasites, or pathogens to manage pest populations. This strategy promotes ecological balance and reduces reliance on synthetic pesticides. By harnessing the natural enemies of pests, biological control can help maintain pest levels below the threshold that would cause economic harm, making it a sustainable choice that aligns with the principles of IPM. The focus of IPM is to employ a diverse array of practices to manage pests in a way that is economically viable and environmentally sound. While other strategies, such as restricting pesticide use or planting resistant crops, can also play important roles in an effective IPM program, biological control specifically leverages natural systems to help control pest populations, thus reducing the need for chemical interventions. This multifaceted approach enhances crop resilience and promotes biodiversity, which are critical components of sustainable agriculture.
