9. Pesticides: Pesticides have made it possible to control and eliminate the plants and animals detrimental for humans and economy. Pesticides in many forms like attractants, insecticides, miticides, acaricides, molluscicides, nematocides, repellants, and rodenticides are used principally to reduce parasitism and disease transmission in domestic animals, the loss of crop plants, the destruction of processed food, textile, and wood products, and parasitism and disease transmission in humans.
