CORN DISEASE ORGANISMS that cause 
seed rotting, missing hills and reduced 
yields may lie in wait on the seed you plant. 
Harmful fungi (molds) such as Diplodia and 
Gibberella are often present on the seed and 
in the soil. They attack the unprotected 
seed, and weaken or stunt the seedling.

TREAT YOUR SEED CORN—To check 
seed rotting and certain seed-borne diseases, 
experiment stations and the United States 
Department of Agriculture recommend 
treatment of seed corn with an ethyl mer- 
cury phosphate dry disinfectant such as 
Semesan Jr. 
MAKES EARLY PLANTING SAFER— 
This low-cost treatment kills most harmful 
organisms on the seed coat, and helps pro- 
tect it from decay by soil-borne organisms. 
Treating seed with Semesan Jr. may save 
replanting, especially in a cold wet spring.

Semesan Jr. increases stands from diseased seed. 
Cold, wet weather at planting time cannot 
now be forecast. Seed treatment with Sem- 
esan Jr. is inexpensive insurance against 
many seedling diseases and seed rotting 
which cause missing hills and hills with only 
one stalk. Fifty-one farm demonstrations 
in the Corn Belt extending over 3 years 
showed that Semesan Jr. increased stands 
5 to 15%. 
The U. S. Dept. of Agriculture says: “... 
treatments usually improve stands and 
yields of field and sweet corn... .” 
HIGHER YIELDS are often secured with 
Semesan Jr. In 9 years’ tests by the Iowa 
Experiment Station, treatment increased 
the yield an average of 4.0 bushels per acre. 
The Illinois Station reported an average 
increase in yield of about 3 bushels an acre. 
Under similar conditions Semesan Jr. may 
help add 4 extra bushels to your acre yield 
—and you can “buy” this increase for 
only 9/10¢ an acre! 


EVERYTHING YOU WANT IN A 
| SEED CORN TREATMENT las 
Treat when Convenient—Dry seed to be 
stored in a dry building may be treated as 
directed with Semesan Jr. at any conven- 
ient time. 




No Clogging in Planter—Semesan Jr. does 
not reduce the planting rate. 
Practically Dustless—Semesan Jr. is prac- 
tically dustless—little flying dust during 
treating and none during planting. 
Safe on Seed—Semesan Jr. when properly 
applied is harmless to seed. Years of use 
prove this! 
Low Cost—One pound of Semesan Jr. treats 
10.7 bushels of seed at a cost of 75¢—only 
9/10¢ an acre! 
Easy to Apply—Mix the correct amount of 
dry Semesan Jr. and seed in a suitable con- 
tainer (see last page). For large quanti- 
ties use a power treater.

Immediate Action— When Sen ee, ‘ 
san Jr. is applied to seed corn, part 
of the active ingredient slowly 
changes to a gas or vapor. This 
vapor is highly effective in killing _ 
the germs and spores in every crack _ 
and cranny on the seed coat, but 
relatively harmless to the seed it-— 
self. This disinfecting action begins 
at once after the seed is treated. 
g 

Long-Lasting Protection—An- 
other part of the active ingredient 
of Semesan Jr. dissolves and is tak- 
en up or adsorbed by the seed coat. 
It rapidly forms on the seed a pro- 
tective film—an armor plate against 
soil-borne organisms—which can- 
not be removed by rains or any 
other natural means. Seed treated 
with Semesan Jr. keeps this pro- 
tective coating almost indefinitely.
