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).
Active ingredients are used to kill, control or repel the pest. Other ingredients may do a variety of jobs, like attracting the pest, spreading the active ingredients around, and/or reducing drift. In order to know the risk associated with a pesticide, both toxicity and exposure must be considered.
