Reduce grain-disease losses and 
increase 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 prove its 
power against smut 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.. One pound treats 32 
bushels. 
Lb. 70 cts., 5 lbs. $3, 25 lbs. $12.75.

Lower costs and better potato yields with 
Prevent Brown-Patch with 
Du Bay Fungicides 
Regular applications of Special 
Semesan, Semesan, or Nu-Green 
prevent or control the develop¬ 
ment of brown-patch and assist 
normal, healthy turf-growth. 
Special Semesan, giving tremen¬ 
dous coverage (6,000 square feet 
per pound), greatly reduces the 
cost of treatment. Semesan is recom¬ 
mended where soil-fertility is high; Nu- 
green where fertility is lower. Free Turf 
Disease Pamphlet gives full details. 
Special Semesan: 5 lbs. $7, 25 lbs. $33, 
100 lbs. $122.85.

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 1cents 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. Treats both seed 
field and sweet corn by the quick, easy 
dusting method. Only 2 ounces needed 
per bushel. 
2 ozs. 15 cts., 4 ozs. 30 cts., lb. 75 cts.,

Improved Semesan Bel 
Closely checked tests have proved that 
any potato grower can usually expect 
better returns from his seed if he treats it 
with Semesan Bel before planting. At an 
average cost of 21 cents an acre this quick 
dip treatment—by reducing seed piece 
decay and seed-borne scab and rhizoc- 
tonia—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.

Semesan reduces seed rotting and damp¬ 
ing-off, is highly effective against many
