Which of the following materials should not be classified as pesticides?

Fertilizers should not be classified as pesticides because they serve a fundamentally different purpose. While pesticides are substances specifically formulated to control, repel, or destroy pests, fertilizers are designed to enhance plant growth by providing essential nutrients. The primary function of fertilizers is to improve soil quality and plant health, rather than to manage pest populations.

Understanding the distinction between these categories is crucial for anyone in the field, as it influences the regulatory requirements, handling practices, and application methods associated with each type of product. Recognizing that fertilizers do not have pesticide properties helps ensure that users apply the correct products for their intended purposes, thereby promoting effective pest management practices and supporting plant health.
