Pesticides are substances or mixtures of substances intended to prevent, destroy, repel, or mitigate any pest. Pests can include insects, weeds, rodents, fungi, and other organisms that pose a threat to crops, livestock, human health, or the environment. The term "pesticide" encompasses a broad range of chemical and biological agents used in agriculture, public health, and household settings.

The use of pesticides has a long history, with early forms like sulfur and arsenic compounds documented in ancient times. Modern pesticides are typically synthesized chemicals, although biological pesticides derived from natural materials such as animals, plants, bacteria, and certain minerals are also used. Pesticides are classified based on their target organism, such as insecticides for insects, herbicides for weeds, fungicides for fungi, and rodenticides for rodents.

While pesticides can be effective in controlling pests and preventing crop losses, their use also raises environmental and health concerns. Some pesticides can persist in the environment, potentially contaminating soil and water. Exposure to certain pesticides has been linked to adverse health effects in humans and wildlife. Regulatory agencies in many countries establish guidelines and restrictions on pesticide use to minimize risks. Integrated Pest Management (IPM) is a strategy that combines various pest control methods, including biological controls, cultural practices, and judicious pesticide application, to reduce reliance on chemical pesticides.
