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).
The route that brings a pesticide in contact with the target pest depends on the nature of the pesticide, how it is applied and the type of environment in which the pesticide is placed. Common application methods include spraying, fumigating and baiting. Many pesticides are 'contact' pesticides.
