Application of fumigants to ships and warehouses. VI. Fumigation of dried fruit with methyl bromide in chambers

These experiments are the first of a series designed to provide safe and efficient fumigation of dried fruit with methyl bromide. Bituminous felt chambers can be used with safety if they are well made and kept in good condition, but loss of methyl bromide exceeds the unavoidable loss by sorption in the fruit and wooden. boxes. With the usual open stacking, distribution and penetration arc satisfactory and only slight improvement is produced by Slow circulation. In these experiments airing for two hours was sufficient to permit unloading. Residues in fruit are extremely small.
