TESTS PROVE IT PAYS... 
Even though your seed is smut-free, it will pay you to 
treat it with New Improved Ceresan to control other seed- 
borne disease organisms. The results of nearly 150 farm 
tests in a dozen states have proved this! 
3.2 Bushels of Oats for 5 Cents 
Eighteen tests conducted in Illinois, Kansas, North 
Dakota and South Dakota in 1932 and 1933 showed that 
Nero Improved Ceresan had increased the yield of oats over 
untreated seed by nearly 4 bushels per acre or about 
11 per cent. 
In 1934 New Improved Ceresan used in 47 tests in 
Georgia, Illinois, Kansas, Minnesota, Nebraska, North 
Carolina and North Dakota increased the yield nearly 3 
bushels per acre or almost 21 per cent. Thus in 65 tests 
over a three-year period New Improved Ceresan treated 
seed oats have outyielded untreated seed by 3.2 bushels 
an acre or over 18 per cent. 
Smut control plus over 3 extra bushels of oats per acre! 
And at a cost of about 5 cents! How much extra would 
that add to your next oats crop profits? 
Barley Yield Increased 6 Per Cent 
Thirty tests on barley during 1932, 1933 and 1934 in 
Illinois, Kansas, Minnesota, Nebraska and North Dakota 
showed that New Improved Ceresan increased the yield 
over untreated seed by nearly 6 per cent. 
To control barley covered smut, black loose smut, stripe 
and seedling blight, U. S. Dept, of Agriculture in Misc. 
Publication No. 199 recommends, among other products, 
ethyl mercury phosphate dust, which is the chemical name 
for New Improved Ceresan. 
Get Your Extra Bushels of Wheat! 
Tests on winter wheat in Georgia and Kansas, as well as 
spring wheat in Minnesota, North Dakota and South 
Dakota—38 tests in all—prove that New Improved Ceresan 
increases the yield even from apparently smut-free or 
clean seed. The average increase in yield was more than a 
bushel per acre or nearly 6 per cent. 
How many extra bushels and dollars would that add to 
your wheat crop? And it takes only 3 cents worth of 
New Improved Ceresan per acre to do it. That’s why we 
say: “ New Improved Ceresan does more than control smut. 
It also frequently increases the yield.”
