by 20 to 25 revolutions of the seed treater, or, by 3 
turnings with a shovel. Seed should be treated 24 
hours before planting. No disagreeable, nauseating 
dust to be breathed—no swollen or injured seed—no 
drill damage for the user of New Improved Ceresan.

TREATMENT OF SEED 
POTATOES PAYS

invested of 9830% 
Seed potato treatment will bring you more profit 
than ever before. New Improved Semesan Bel—the 
quick dip treatment—has cut treating costs to 1/^c. 
to 3c. per bushel of seed and gives equal or better 
control of seed-borne Rhizoctonia and scab than the 
old soak treatments. It protects seed pieces against 
rotting, insuring maximum stands; gives more con¬ 
sistent increases in yield and consequently larger profits. 
It costs less in time and labor than the old treatments. 
It is easily and quickly applied. Just mix one pound 
of Improved Semesan Bel with 7^2 gallons of water, 
dip your seed potatoes, drain, and plant. One pound

DISEASE PROTECTION FOR 
Vi TO lc PER POUND OF SEED 
Prevent the many damaging diseases of flowers and 
vegetables that are carried on the seed, by disinfection 
of the seed with Semesan. It destroys the destructive 
diseases on the seed and protects them from the rots in 
the soil, which results in increased stands of more 
vigorous, healthy plants that yield larger, quality crops. 
Sprinkling of the seedling beds with Semesan solution 
effectively prevents damping-off. Recommended espe¬ 
cially for seeds, bulbs, gladiolus corms, dahlia tubers, 
and rose bushes. Easily applied as a liquid or dust. 
One ounce treats 15 to 30 pounds of seed.

New Improved SEMESAN JR. 
INCREASES STANDS AND YIELDS 
Semesan Jr. increased the yield of field corn 21.3 bushels pe 
acre over the untreated seed planted in the same fieldr 
Four bushels more corn per acre can reasonably be 
expected by any farmer that treats his seed corn 
before planting, Illinois Experiment Station tests show. 
Field or sweet corn dusted with New Improved 
Semesan Jr. is protected from destructive Diplodia 
and Gibberella root rot carried by the seed, and from 
rotting in the cold, wet soil. New Improved Semesan 
Jr. insures better stands and yields of corn. In 26 out 
of 28 tests, it increased the yield as high as 22 %, and 
gave an average increase of nearly 10%. It does not 
reduce the rate of planting The cost of treating field 
corn is only approximately 2 to 3c. per acre. 
Prices: 4 oz., 50c.; 1 lb., $1.50; 5 lb., $7.00;
