ABSTRACT

A pesticide is any substance used to avoid pests in plants and animals. During the 1970s and 1980s, public and regulatory attention to these compounds increased, resulting in banned many traditional pesticides. Despite that, new groups of pesticides have appeared. They are called “currently used” or “modern” pesticides, a general term to describe a diverse group of chemicals. Pesticides are classified in different ways: One division is based on the chemical family they belong to, such as organophosphorus, triazines, carbamates, triazoles; another grouping approach is based on the type of organism they control, for instance herbicides (plants), insecticides (insects), and fungicides (fungi), etc. [1].
