TREATMENT OF STINKING SMUT IN WHEAT. 7 
Plat No. II, planted with grain sprinkled with copper 
sulphate in proportion of one pound copper sulphate to four 
gallons of water; this gave the solution a dark blue color. 
One-half of one per cent, was the result. This result is 
much better than could be expected from the seed used. 
Plat No. III. Planted with grain soaked ten minutes 
in a solution of corrosive sublimate in the proportion of one 
pound to fifty gallons of water. This gave one-half of one 
per cent, of the grain diseased. 
Plat No. IV. Planted with grain sprinkled with corros¬ 
ive sublimate in the proportion of one pound to fifty gallons 
of water, this gave the results of one-half of one per cent, 
of the grain diseased. These results prove that sprinkling 
is as good a method of treating as soaking. 
Plat No. V. Planted with grain soaked two minutes in 
a solution of copper sulphate, in proportion of one pound 
copper sulphate to four gallons of water, giving results of 
one-half of one per cent, of the grain diseased. 
Plat No. VI. Planted with grain sprinkled with a solu¬ 
tion of formalin in proportion of one pound formalin to 
forty-five gallons of water. Scarcely a smutted head could 
be found in the plat. This result not only shows that for¬ 
malin is a good remedy, but it also shows that the sprink¬ 
ling method can be depended upon. 
Plat No. VII. Planted with grain sprinkled with a 
solution of potassium sulphide in proportion of one pound 
to eight gallons of water. This gave very poor results, 
seventy-five per cent. smut. The solution was probably a 
little weak, but the result obtained shows that it could hard¬ 
ly be made strong enough to be a complete prevention. 
Plat No. VIII. Grain soaked 12 hours in a^weak solu¬ 
tion of copper sulphate, one pound to twenty-four gallons 
of water. Result five per cent, of diseased wheat. 
Plat No. IX. Planted with|]grain mixed with slaked 
lime in proportion of one-fourth pound lime to twenty 
pounds of grain, this gave poor results, fifty per 'cent. smut. 
With the use of any more lime the grain could not be sown 
evenly. 
Plat No. X. Planted with untreated grain, the results 
of eighty per cent, of the grain diseased.
