What does the term pesticide refer to?

The term "pesticide" specifically refers to a chemical agent used to kill pests. This encompasses a broad range of substances intended for controlling various unwanted organisms, including insects, weeds, rodents, and other pests that can harm crops, livestock, and human health. Pesticides can come in different forms, such as herbicides (for weeds), insecticides (for insects), and fungicides (for fungi).

Understanding the function of pesticides is crucial in various industries, including agriculture, where they play a significant role in protecting food production and quality. While other options include terms related to pest management and agriculture, they do not define pesticides or encompass the chemical nature and intended use of pesticides accurately. For example, while a plant used for natural pest control reflects a form of pest management, it does not fit the definition of a pesticide, which is a specific chemical agent. Similarly, a method for organic farming does not involve synthetic pesticides, and food safety certification pertains to the safety standards related to food production and handling, not pest control.
