A Treatment for Cotton and Other Major Crops 
Bigger cotton yields and more profit with 
2% CEBESAN. Cotton States Authorities 
report big profit increases with 2% Ceresan 
cotton seed treatment — North Carolina, 
$13.08 an acre; South Carolina, $9.08 an 
acre; Texas, $6.30 an acre. Dusted on seed, 
2% Ceresan reduces seed rotting and damp¬ 
ing-off, gives growers more uniform stands 
with less seed. In 40 recent tests, 2% Cere¬ 
san increased the average stand 59.8% be¬ 
fore chopping; 30.8% even after chopping— 
and increased the average yield 16.4%. 
Saving in seed and replanting expense alone 
easily pays the small cost of 2% Ceresan. 
One pound treats 5 to 6 bushels. Prices: 
1 lb., 70c; 5 lbs., $3.00. Postpaid, 1 lb., 80c; 5 lbs., $3.20. 
Not prepaid, 25-lb. pail, $12.75; 100-lb. drum, $47.60; 300-lb. 
drum, $130.05. 
Reduce grain disease losses and in¬ 
crease yields with NEW IMPROVED 
CERESAN. Use this dust treatment on 
seed wheat, oats and barley to reduce 
seed-borne disease, step-up your yield, 
increase your profit. Tests by Experiment 
Stations in most important grain states 
prove its power against covered smut, 
black loose smut and stripe of barley; 
loose and covered smuts of oats; stinking 
smut of wheat; and seedling blight of all 
three. Increased yields repay its small 
cost many times. Easily dusted on seed 
grain as directed may be applied as long 
as 3 months before sowing. No dust in 
drilling, no drill damage, no change in drilling rate, apd 
only about half the cost of other dust treatments. One 
pound treats 32 bushels of seed grain. Prices: 1 lb., 70c; 
5 lbs., $3.00; 25-lb. pail, $12.75. Postpaid, 1 lb., 80c; 5 lbs., 
$3.20. 
Dower costs and better potato yields 
with IMPROVED SEMESAN BED. Close¬ 
ly checked tests in 15 states have proved 
that any potato grower can usually ex¬ 
pect better returns from his seed if he 
treats it with Semesan Bel before plant¬ 
ing. At an average cost of 21 cents an 
acre, this quick-dip treatment—by reduc¬ 
ing seed piece decay and seed-borne scab 
and Rhizoctonia—increased the average 
yield 13.6%. Result—lower growing cost 
and more profit! No mussy soaking. 
Treat your seed as fast as you can dip it. 
One pound treats 60 to 80 bushels of seed 
—easily, quickly, inexpensively. Prices: 
4 ozs., 45c; I lb., $1.50; 5 lbs., $6.75. Postpaid, 4 ozs., 50c; 
1 lb., $1.60; 5 lbs., $6.95. 
Make sure of a better corn yield by 
treating seed with SEMESAN JR. Seed 
corn treatment with Semesan Jr. amounts 
to real crop insurance. At the extremely 
low cost of 1% cents an acre, it reduces 
seed rotting, checks seedling blight and 
certain seed-borne rots of root and stalk 
—gives corn the healthy start necessary 
for a big yield. Circular 444, Illinois, 
where the average yield increase has been 
about 3 bushels an acre, says Semesan Jr., 
is “one of the best disinfectants for seed 
corn now on the market. . . .”. Treats both 
seed field and sweet corn by the quick, 
easy dusting method. Only 2 ounces needed 
per bushel. Prices: 4 ozs., 30c; 1 lb., 75c; 5 lbs., $3.25. 
Postpaid, 4 ozs., 35c; l lb., 85c; 5 lbs., $3.45. 
Disease control—better stands—stur¬ 
dier plants with SEMESAN. Don’t trust 
to luck for success with vegetables and 
flowers. Do what you can to control con¬ 
ditions. Treat your seeds, conns, bulbs, 
and seedlings with Semesan! Used as a 
dust or in solutions with water, Semesan 
reduces seed rotting and damping-off, is 
highly effective against many seed-borne 
diseases, even prevents contamination of 
the soil by certain seed-borne diseases. 
One ounce treats 15 to 30 pounds of 
seeds at a cost of % cent to 1 cent a 
pound of seed. Prices: 2 ozs., 35c; 1 lb., 
$2.25; 5 lbs., $9.90. Postpaid, 2 ozs., 40c;
