Attenuation of pesticidal residues on seeds, individuals. Because at this period one cannot predict weather, infestation, disease, or epidemic conditions with certainty each year much more seed has to be treated than is used. Despite our relative sophistication, second and third plantings are common. It, therefore, becomes necessary each year

Effects of processing on pesticides in foods,n’s environment. The length of time they will remain in the environment and find their way into biological systems is not known. As a result of this persistence they are translocated in water, soil, plants, and animals throughout the food chain until they reach man’s food supply. M. (1965) summarize
