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).
They are a class of biocide. The most common use of pesticides is as plant protection products (also known as crop protection products), which in general protect plants from damaging influences such as weeds, plant diseases or insects.esticides can be classified by target organism (e.g., herbicides, insecticides, fungicides, rodenticides, and pediculicides-see table), chemical structure (e.g., organic, inorganic, synthetic, or biological (biopesticide) , although the distinction can sometimes blur), and physical state (e.g. gaseous (fumigant)).
