Increase Your Farm Profits by Lowering 
Production Costs With 
DUBAY SEED DISINFECTANTS 
Ceresan treatment repays its low cost many times over in 
extra profit. Four pounds of cotton out of 294 pounds 
increase in yield paid for the Ceresan.

CERESAN for Cotton 
(ALSO FOR SEED GRAINS) 
Lower Acre Costs of Cotton and Grains by 
Increasing Stands and Yields with CERESAN 
With this new seed treatment, Ceresan, you can now plant cotton earlier 
because Ceresan, which is applied to the seed as a dust, protects the seed against 
rotting. Early planted cotton also is less susceptible to attacks by boll weevil. 
The use of Ceresan as a seed treatment prevents heavy plant losses caused by 
damping off and results in a uniform stand of vigorous plants. 
Ceresan is easily applied as a dust at the rate of 2 to 3 ounces to the bushel. 
Since Ceresan produces a uniformly better stand of plants, the quantity of seed 
sown per acre may be reduced. 
In one test with cotton, Ceresan-treated seed showed an improvement of 76% 
in stand over the untreated. The saving in seed, the better stand, freedom from 
disease and increased yield more than repay the small cost of this remarkable 
treatment. 
Ceresan should also be used to treat your seed, wheat, oats, barley and 
sorghums. Prevents smuts and barley stripe. Use 2 ounces per bushel of 
sorghum, 3 ounces per bushel of wheat, rye and sorghum, 3 ounces per bushel of 
oats and barley. Results show Ceresan controlled smut on oats and increased 
yields. Costs less than three cents per acre. I bu. tin, 75c; 5 lb. tin, $3.00; 25

One and a half billion dollars—an average of over $200 per farmer— 
is the annual tax levied by plant diseases on America’s crops, according 
to estimates of the U. S. Department of Agriculture. Truly a staggering 
economic waste which makes diseases one of the most important risks in 
crop production. 
Du Bay Seed Disinfectants pay large profits by destroying disease organ¬ 
isms before they can do damage; by preventing seed rotting in cold, wet 
soils ; by reducing damping-off of emerging seedlings ; by producing better 
stands of more vigorous plants; by-increasing yields; and by improving 
crop quality. 
Semesan Bel 
For Seed Potatoes 
Instead of using chemicals for treating 
seed potatoes which require tedious soak¬ 
ing and which sometimes injure the seed 
piece, use the quick, easy, time-saving Seme¬ 
san Bel treatment. Simply mix, dip, drain, 
dry and the potatoes are ready for planting. 
No hot water necessary. By controlling these 
diseases, germination is generally increased, 
stand improved and the resultant crop of 
potatoes is bigger and of better quality. Crop 
increases of from 10% to 15% are common. 
One pound treats 70 to 80 bushels of seed.

For Cotton 
1— Controls damping-off, caused ; 
by seed-borne and certain soil- 
borne organisms and seed rot¬ 
ting. ' 
2— Reduces damage caused by 
angular leaf spot, anthracnose 
and boll rots. 
3— Makes possible earlier planting 
and produces heavier stands. 
4— Generally produces heavier 
yields of better quality. 
For Seed Grains 
Controls wheat stink smut and 
stripe and covered smut or barley 
without injuring the seed.

Semesan 
For Vegetable and Flower Seeds 
Semesan should be applied in dust or 
liquid form to flower or vegetable seeds be¬ 
fore planting. It is harmless to the seed, 
but deadly to any disease organisms that 
may be on the seed. One ounce treats 15 to 30 
lbs. of seed. Effective in controlling damp¬ 
ing-off, many seed-borne diseases and such 
devasting gladiolus diseases as hard rot 
and scab.

Semesan Jr., New Improved 
For Seed Corn 
Applied by the simple dusting method at 
the rate of 2 ounces to each bushel of seed 
field or sweet corn, Semesan Jr. offers the 
cheapest and most effective form of disease 
insurance. U. S. Government tests show 
Semesan Jr. increased the yield of disease- 
free seed as much as 1.9 bushels an acre. 
Its use protects the seed from rotting in 
the ground and makes possible earlier plant¬ 
ing which generally results in increased 
yields. 
Costs less 
than three cents per acre.
