Inert dusts have been used traditionally as stored grain protectants. The Aztecs of ancient Mexico are said to have mixed maize with lime to preserve their grain (Quintana, R, pers. comm.). It is, however, only in the last fifty years that specific attempts have been made to commercialise these materials for use in modern grain protection technology.
These dusts primarily exert their effects on insects through physical means and, although they do not affect metabolic pathways by chemical action, they may well be chemically active under some circumstances. There are five groups of inert dusts which can be differentiated by their chemical composition or by their level of activity.
