BULLETIN 79. 
SUMMARY. 
I. The results obtained in these experiments are re¬ 
markable because the seed used was so badly diseased. No 
one would think of using such grain for seed. With ordi¬ 
nary seed the treatments that gave the best results, would 
insure a crop entirely free from smut. 
II. The sprinkling method proves to be as effective as 
the soaking method. 
III. Copper sulphate, corrosive sublimate and forma¬ 
lin prove to be efficient remedies. 
IV. Copper sulphate in a weak solution will not do 
good work even when allowed to soak a long time, twelve 
hours for instance. 
V. Potassium sulphide is a very poor remedy for smut 
besides being expensive. 
VI. Sprinkling with copper sulphate is recommended to 
be the best remedy. Solution, one pound of copper sul¬ 
phate to four gallons of water. It is the cheapest, the 
handiest to use and gives as good results as any treatment 
tried. 
VII. The smut is planted with the grain and germi¬ 
nates at the same time. If the seed is free from smut then 
the crop will be unless volunteer grain comes up in 
the field. 
VIII. To treat the grain by the sprinkling method, 
place the grain in a bin large enough so the grain can be 
shoveled from one side to the other. Sprinkle the solution 
on with a common watering pot and at the same time keep 
shoveling the grain over and over. When the kernels are 
all wet the treatment is finished, but great pains must be 
taken to see that the work is thoroughly done. 
IX. Because the grain is clean one year do not run the 
risk of its being free from smut the next, but treat every 
year. 
X. The grain should not*be treated very long before 
it is planted because it will start growing. After treatment 
it should be allowed free circulation of air so that it will dry 
quickly. 
XI. The sprinkling method is by far the quickest and 
easiest method. If the user does not have a floor to spread 
the grain out while treating, a canvass, or any large cloth 
can be used.
