Which item is commonly used in pest management strategies?

Pesticides are commonly used in pest management strategies due to their primary function, which is to eliminate or control pests that can damage crops, harm livestock, or threaten public health. They are formulated to target specific types of pests, including insects, weeds, fungi, and rodents, thereby playing a crucial role in maintaining agricultural productivity and protecting ecosystems.

In pest management, the use of pesticides is often a critical component of an integrated pest management (IPM) approach. This strategy emphasizes the importance of combining various methods of pest control to minimize environmental impact and promote sustainable practices. While other options such as fertilizers, herbals, and nutrients are important in agriculture, they do not directly address pest control in the way that pesticides do. Fertilizers enhance plant growth, herbals might be used for certain natural remedies, and nutrients are essential for plant health, but none of these items serve the specific purpose of managing pest populations like pesticides do.
