A larger amount of carbon disulfide is needed for the treatment of unshucked corn than in treating an equal volume of shucked or shelled corn. The amount of liquid to use for each thousand cubic feet of space in a bin of shelled corn is from 10 to 20 pounds if the crib is very tight and the weather warm.

Since these fumes are heavier than air, the liquid may be placed in shallow vessels near the top of the pile of grain; or it may be poured directly on the top of the pile of corn. It is best to cover the pile while under treatment with grain sheets or other heavy cloth, leaving it thus tightly covered for twenty-four hours.
