SEED CORN TREATMENT PAYS 
REDUCES SEED ROTTING 
Seed rotting—one of the most 
frequent causes of missing 
hills and hills with only one 
stalk—means lower yields, 
less profits. Regardless of the 
care taken in selecting your 
seed corn, or the price paid 
for it, the seed may rot in the 
ground. No one can predict 
the weather, especially early 
in the season, with sufficient 
Diplodia root-rot growing accuracy to be certain that 
on seed com they can plant untreated seed 
corn with assurance that it will not rot. 
Seed corn, besides being exposed to rot organisms 
living in the soil, carries on itself root-rot fungi such as 
Diplodia and Gibberella, which also cause seed decay 
and seedling blight. The Illinois Experiment Station 
reports: “No seed corn of which there is enough for 
farm use is entirely free from diseases .... The average 
farmer’s seed is rather badly diseased. This causes a big 
decrease in yield which the farmer can ill afford.”

The cheapest and surest method of protecting the 
seed corn from rotting and the seedling from blighting is 
to treat the seed before planting with New Improved 
Semesan Jr. A little time spent in testing the seed for 
germination, and a small investment of 1Jtjc an acre for 
New Improved Semesan Jr. you will find profitable. 
IMPROVES STANDS 
Every grower knows the importance of securing good 
stands of healthy plants. But good stands, especially 
from early plantings when the soil is cold and wet, are 
hard to get. 
Treatment increases stands from root-rot infected seed 
New Improved Semesan Jr. helps to give you better 
stands by generally protecting the seed from rotting and 
the seedlings from blights and certain root-rots. This 
has been demonstrated by 51 farm tests in the Corn-Belt 
states, where New Improved Semesan Jr. increased 
the stands over untreated seed by 5% to 15%. 
Treatment also largely eliminates the small, weak 
plants which are stunted in the seedling stage by attacks 
of certain fungi (mold) carried on the seed or living in 
the soil. At harvest, many of these stunted plants are 
barren or produce only nubbins. It doesn’t pay to 
gamble on getting a 
stand, because treat¬ 
ing seed corn with 
New Improved Sem¬ 
esan Jr. is such an easy 
job—so easy on the 
pocketbook, too, be¬ 
cause it costs only 1 J^c 
an acre. Even if its 
price were higher, the 
better stands would 
amply repay you for 
using it.

BIG PROFITS! 
INCREASES YIELDS 
Treatment of heavily diseased seed increases yields as much as 
21 bushels per acre 
The better stands and more vigorous plants produced 
by New Improved Semesan Jr. treated seed give 
greater yields. In tests on 17 farms, New Improved 
Semesan Jr. increased the yield on 15 of them. On 6 of 
these farms the increase ranged from 5 to 8 bushels an 
acre. The next year, on 26 out of 28 farms in 20 counties 
scattered over 4 of the largest corn-growing states, 
New Improved Semesan Jr. increased the yield 1M to 
New Improved Semesan Jr. generally will add 
about ten per cent more yield 
6bushels per acre. Treating seed corn usually in¬ 
creases the yield about 10% on the average good Corn- 
Belt farm. If your seed, soil and weather make 50 bushels 
per acre. New Improved Semesan Jr. under most con¬ 
ditions generally will add about 5 extra bushels to each 
acre. That’s why it is profitable to treat seed corn 
with New Improved Semesan Jr.
