Ceresan 
Barley — Stripe and covered 
smut are usually eliminated by 
the use of this simple dust treat¬ 
ment. Ceresan is the first satis¬ 
factory dust disinfectant avail¬

ley diseases. 
Oats — Excellent control of 
loose and covered smuts may 
generally be obtained by seed 
treatment with Ceresan. 
Wheat—Ceresan is very effective in the con¬ 
trol of bunt or stinking smut and is recom¬ 
mended for the control of seed-borne flag smut.

diversified variety of 
parasitic diseases and 
fungoid growths borne 
by seeds, plants, grafts 
and soil. Semesan is 
harmless to seed and 
plant life but extreme¬

Semesan 
For most flower and vegetable seeds use one 
ounce of Semesan to each 15 pounds, but to dust 
field crops use two ounces per bushel for the 
In six farm tests Semesan Bel gave an average 
yield increase of 35.4 bushels. The untreated av¬ 
eraged 259.9 bushels, the treated 295.3 bushels. 
Disease steals your potato profits by decreas¬ 
ing the yield and lowering the market value. 
Your profits can be greatly increased by using 
Improved Semesan Bel. Thirty-five and four- 
tenth bushels of potatoes an acre is the average 
increase in yield secured in demonstrations with 
Improved Semesan Bel on six practical farms in 
Maine, Minnesota, Ohio, Pennsylvania, and New 
York. 
An illustration of Semesan Bel’s effectiveness 
in seed-piece preservation: Untreated—38% rot¬ 
ted and 62% sound seed pieces. Semesan Bel 
treated—7% rotted and 93% sound seed pieces. 
Rhizoctonia and seed rotting are responsible 
for a large portion of yield losses, while Rhizoc¬ 
tonia and scab account for lowering of market 
value. These needless losses can be largely pre¬ 
vented by treating the seed, before planting, with 
Improved Semesan Bel. In addition to killing 
seed-borne diseases Improved Semesan Bel pro¬ 
tects the seed pieces from rotting under cold, wet
