N2  - Series of experiments were conducted during 1991-1997 at Nakhon Sawan Field Crops Research Center and at a merchant warehouse in Nakhon Sawan province. It was found that carbon dioxide fumigation of the wet grain bulk under plastic sheet could effectively control fungal infection and aflatoxin contamination. Two methods of fumigation were developed. In the first method, the sealed bulk was only fumigated by carbon dioxide at a rate of 0.5 kg/ton. In the second method, the sealed bulk was firstly vacuumed by a vacuum machine then fumigated by carbon dioxide at a rate of 0.3 kg/ton. These methods could preserve the quality of the wet maize with moisture content below 30 % within 48 hrs after shelling. The treated grain bulk could be protected from fungal infection and aflatoxin contamination for at least 10 days. After fumigation, the maize quality and appearance were not changed. The grain color remained bright and free flowing. The temperature in the grain bulk was not increased. However, an anaerobic fermentation in the bulk produced a sour-sweet smell that would disappear after sun drying
