Abstract
A pesticide is defined as any substance or a mixture of substances intended for preventing, destroying, repelling or mitigating a pest. Pesticide is a general classification and include a variety of chemicals with different uses. Pesticidal chemicals have the capability of destroying life of some form. The organisms against which they are directed are deemed to be undesirable by the person or society that applies them. â€کThere is a great difference in pesticides types of action and primary target tissues as there is diversity in their chemistry and physicochemical properties (Murphy, 1980).
