ABSTRACT
Pesticides are chemical substances used for controlling pests. The Environmental Protection Agency (EPA), which is the primary regulator of pesticides in the United States, denes a pesticide more precisely: A pesticide is any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest. Pesticides include insecticides, nematicides, rodenticides, herbicides, and fungicides. They are the largest group of poisonous substances that are widely broadcast today. There are approximately 1,200 active ingredients approved for use by the EPA from which over 20,000 pesticides products are formulated and are being marketed in the United States.
