Since the beginning of the 1939–45 war, changes in storage, transport and processing of foodstuffs have demanded new methods of pest control. The methods then available in this country were derived either from the Imperial College investigations, e.g. the use of pyrethrum sprays in warehouses or fumigation with ethylene oxide, or from work carried out mainly by commercial interests in U.S.A. or Germany. Such procedures were the use of liquid and of absorbed hydrogen cyanide which were employed here by commercial servicing companies who did not maintain research or development sections in Great Britain. It is now evident that the techniques available here, and their practical application, were considerably behind those in various foreign countries; we now know, for example, that there were many grain silos in Germany already equipped with gas circulation apparatus in 1939, whereas in this country there were none.
