A fumigant made by mixing 40 parts of ethyl acetate and 60 parts of carbon tetrachloride has been recommended for the fumigation of grain in grain cars when used at the rate of 40 to 50 pounds per thousand cubic feet of space (U. S. Department of Agriculture Bul1etin 1313). Experiments reported upon here with indicate that good results may fol1ow its use in very tight containers in household fumigation and in wel1 constructed covered grain bins on the farm. Fumigation of slip shuck corn during October in South Georgia proved a failure when conducted in well constructed wooden cribs in which carbon disulphid has been used succcssful1y. It would seem that the ethyl acetate-carbon tetrachloride mixture requires a tighter container than carbon disulphid and possibly a higher minimum temperature. The new mixture must be made of pure or very nearly pure chemicals since the odoriferous constituents will taint grain and flour. The new fumigant is more expensive than carbon disulphid (costing f. o. b. Baltimore, from 12 to 15 cents per pound) has not injured the viability of seeds tested and produces a gas that is non-explosive and noninflammable at ordinary temperatures.
