Pesticides are substances or mixtures used to control, repel, or eliminate pests, which can include insects, weeds, fungi, rodents, and other organisms that can harm crops, animals, humans, or the environment. Pesticides are widely used in agriculture, public health, and other industries to manage various pest-related problems

Pesticides can be classified based on their chemical composition and mode of action. They can be synthetic (human-made) or natural (derived from natural sources). While pesticides have significantly contributed to increased crop yields and disease control, there are also concerns about their potential negative impacts on human health, non-target species, and the environment. Misuse or overuse of pesticides can lead to pesticide resistance in target pests, environmental pollution, and unintended harm to beneficial organisms.
