It pays to dust-treat seed 
corn with New Improved 
Semesan, Jr. It assures a 
better yield. The reasons: It checks seed-rotting in the ground; improves 
the stand; and reduces losses from seed-borne root and stalk rots. 
In 51 tests made over a wide area of the country, careful checks were 
made. Certain parts of the plantings had been treated with New Im¬ 
proved Semesan, Jr.—other parts had not. The result of these 51 tests 
showed an average of 3^ bushels gain per acre in favor of the treated 
seed acreages. One very noticeable gain was 6]/ 4 bushels per acre. . . . 
How else could 3^ or more bushels of corn be gotten so easy? A trifling 
bit of work to apply the dust to the seed—and about 2^/ 2 cents spent on 
enough Semesan, Jr., to treat an acre of seed corn! 
There’s nothing mysterious about this whole idea increasing corn crops. It’s 
simple as can be. This modern dust method usually produces a better stand 
of healthier plants. Why wouldn’t that increase the yield? It’s just exactly 
what you would expect. 
Semesan, Jr., will not control corn smut, wire worms, and grubs. Neither 
will it prevent damage by animals or birds. It is not designed for such pur¬ 
poses. It does help protect the seed from decaying, and the seedlings from 
blights and root rots caused by various fungi. You’ve often noticed when 
riding the cultivator how some plants were much higher than others. Ofttimes 
those small plants have been stunted by attacks of certain fungi or molds. 
They cannot then be expected to produce as well as if they grew up to be 
strong healthy plants. 
Semesan, Jr., won’t cause any planter trouble. ... It is very finely ground— 
literally smooth as silk, no friction. Is dropped easily by the planter. 
This treatment will pay its 
cost many times over. . . . 
It certainly has. been doing just 
that, year after year. Two 
ounces of New Improved 
Semesan, Jr., treats 1 bu. seed. 
Four-ounce can costs you 35 
cents; 1-pound can, $1.00; 
5-pound can, $4.75; 25-pound 
pail, $23.25.
