What is the primary purpose of a pesticide?

The primary purpose of a pesticide is to control or eliminate pests that harm crops, plants, or human health. Pesticides are specifically formulated to target organisms that negatively impact agricultural productivity, such as insects, weeds, fungi, and pathogens. By managing these pests, pesticides help protect plants and ensure healthy growth, thereby supporting food production and safety for humans.

While some of the other options touch on aspects related to plant health and gardening, they do not accurately represent the fundamental function of pesticides. Enhancing plant growth, fertilizing the soil, and improving aesthetic appeal are important aspects of horticulture and agriculture, but they are not the primary purpose of pesticides. Instead, those functions are typically addressed through different agricultural practices, such as the use of fertilizers and soil amendments.
