^Reduces Seed Rotting 
Every corn grower knows 
the imports nee of securing 
a good stand of vigorous 
plants. But good stands, 
especially for early plantings 
or when the soil is cold and 
wet, are hard to get. Too 
many missing hills and too 
many hills with only one stalk 
usually leave a stand that is 
only fair. That’s what cuts 
into your corn income year 
after year. 
Seed decay and seedling blights seriously handi¬ 
cap the grower in securing good stands. Such fungi 
or molds as Diplodia, Gibberella, and others attack 
the germinating seed or the young seedling causing the 
seed to rot or the seedling to be stunted and weak, 
resulting in poor stands. These destructive fungi live on 
most seed and in most soils. The University of Illinois 
says: “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.’’

New Improved Semesan Jr. helps to protect the 
seed from rotting. This efficient chemical disinfec¬ 
tant, dusted on the seed before planting, generally 
destroys the disease germs (spores) on the surface of 
the seed and protects it from those in the soil. Treated 
seed are less likely to rot even in cold, wet soils. 
X Improves Stands 
New Improved Semesan Jr. usually increases 
stands. Its disinfecting action helps to protect the 
seed from rotting and the seedling from blighting. 
Fifty-one farm demonstrations in the Corn Belt showed 
Treated 
Treatment increases stands from root-rot infected seed 
that New Improved Semesan Jr. increased the 
stands by 5% to 15%. 
Seed treatment with New Improved Semesan 
Jr. reduces the number of weak plants. While 
riding the cultivator, have you ever noticed how many 
plants were only a foot high when the others were 
twice as tall ? There’s a reason for those small plants. 
Most of them have been stunted during the seedling 
stage by the attacks of certain fungi (molds) carried 
on the seed and in the soil. At harvest time most of 
those stunted plants will be barren or will produce 
only nubbins. No seed treatment can grow a big ear 
on every stalk, but New Improved Semesan Jr. can 
reduce the number of these weak, stunted plants. 
Iowa State College 
says: “In most cases 
good treatment will 
give a more uniform 
stand and also result 
in an increase in yield 
ranging from 1 to 15 
bushels per acre, de¬ 
pending on (1) season¬ 
al conditions, (2) time 
of planting, and (3) 
condition of the seed 
used.”
