The loss from smut on Oats and Barley runs into millions of dollars 
annually, being estimated by one authority at $16,000,000. It is not 
uncommon for Smut to cause as high as 25% loss of a farmer’s entire 
crop. 
Smut is caused by a fungus which enters the plant soon after the 
grain germinates. The seeds or spores of Oat and Barley smut adhere 
to the roughened surfaces of the grain and in the crevices of the 
hulls. They germinate along with the grain and soon enter the young 
tender plants where the fungus continues to grow and develop as a 
parasite until it matures. 
Dry Dusts, which contain penetrating gases are rapidly replacing 
the wet grain treatments formerly recommended as the best control. 
The cost per acre is comparatively small, not exceeding 12c. Formo- 
Dust is rapidly and easily applied. It liberates the gas rapidly enough 
to kill smut spores without injuring the grain in the process of germi¬ 
nation. Grain should be treated at least 12 hours before sowing. It 
is not injurious to stock and treated grain, if left over after sowing, 
may be fed with safety. It requires 2 1 /j> to 3 ounces of Dust per 
bushel of grain. A 5 lb. can will treat 25 to 30 bushels. Price, per 
5 lb. can, $1.50.
