The fate of pesticide in the environment.
Pesticides are an essential element of agriculture production. Increased use of pesticides has greatly aided agricultural production, decreased losses of stored grains, and has generally improved man’s welfare. However, pesticide usage may lead to undesirable residues as trace contaminats of food, the environment and living tissues. Pesticides are known to move from treated agricultural areas into the broader environment, then they can reach to the non-target organisms. Once pesticides enter the atmosphere, they may be transported long distances. The escape of these chemicals into the atmosphere represents an economic loss to the user, inefficient control of pests, and introduction of possible environmental contamination. With the basis of update references, this article deals with; movement of pesticides from the site of application, environmental behaviour of pesticide and fate of pesticide in the soil-plant system.
