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).
1 The herbicides kill weeds as they grow through the herbicide treated zone. 2  Volatile herbicides have to be incorporated into the soil before planting the pasture. 3  Agricultural crops grown in soil treated with a preplant herbicide include tomatoes, corn, soybeans and strawberries. Non-selective herbicides: These herbicides are not specific in acting against certain plant species and kill all plant material with which they come into contact. 2  They are used to clear industrial sites, waste ground, railways and railway embankments.
