Pesticides are chemicals used to eliminate or control a variety of agricultural pests that can damage crops and livestock and reduce farm productivity. The most commonly applied pesticides are insecticides (to kill insects), herbicides (to kill weeds), rodenticides (to kill rodents), and fungicides (to control fungi, mold, and mildew).
Pesticide chemicals and their metabolites may be stored or accumulated within an organism or be eliminated as waste. Metabolism can be induced based on exposure. Because pesticide residues may accumulate within organisms, special precautions in harvest or slaughter must be observed with the treated commodities.
