A substantial part of the annual grain crop is destroyed during storage through the action of insects, mainly of the two grain weevil species, Sitophilus (Calandra) granaria L. and S. oryzae L. In modern granaries and silos specially constructed to facilitate fumigation the control of these insects no longer constitutes a problem. Risk of contamination, however, still exists in the open storage sheds of farms, where the highly poisonous fumigants, like methyl bromide, cannot be applied without certain drawbacks. The newer synthetic insecticides applied in dust form to various stored products have given outstanding results. For the use in grain, which is destined for human or animal consumption, however, only those compounds can be applied that are potent insecticides at very low concentrations, and which at the same time do not create any hazards for future consumers taking small quantities regularly in their daily diet.
