The stinking smut of wheat is a disease so common as to be very familiar to the farmers of South Dakota. Its presence can be easily detected by the characteristic smutted kernels in the threshed grain and by the disagreeable odor. So much has been written upon the details of the growth of the parasite which causes the disease that the facts with not be taken up or discussed in this bulletin. . . . In view of these facts the writer in the winter of 1903-04 began a series of experiments to secure a treatment for smut which would not necessitate the wetting of the seed grain. The experiments were begun before any search of the literature upon the subject was made to determine whether similar experiments had been conducted previous to this time. Later upon investigati.ng the literature it was found that various botanists had conducted experiments with this object in view but in no case had these progressed beyond the first stages of experimentation. Some of the experiments recorded here are therefore to a certain extent a repetition of the experiments of others. It was also discovered that a powder commercially known as “Ozonet gas powder" had been offered for sale to be mixed with seed grain for the prevention of smut.
