Study on pesticide residue in fruits and vegetables

Abstract

The term pesticides includes insecticides, fungicides and herbicides together with rodenticides, nomaticides, molluscides, and acarides. Those are agrochemicals designed to control the various attacks of pests in agriculture and horticulture. Modern pesticides exert a systemic mode of action. They enter the plant's vascular system via its cuticle. Man's fight against pests dates back to ancient times, and we note various land marks in history when pesticides were introduced. The introduction of Paris green and Bordeaux Mixture in 1800s to control the Colorado Beetle and other pests I diseases led to the enactment of first law, in the USA in 1900, about pesticides. However it was not until the second world war that the revolutionary DDT was introduced. It was one of the first synthetic organochlorine. Later on a new generation organophosphates based on nerve gasses came into being. In 1959 both the FAO and the WHO then started to issue regular studies and regulations regarding pesticide use and their effects on man, animal and environment. Later on both organizations complied the concepts of ADI, MRL and GAP .
