SEMESAN 
BEL 
Low-Cost Treatment for 
INCREASING 
POTATO YIELDS 
Dip-treat your seed potatoes 
with New Unproved Seme- 
san Bel this season . . . and 
look forward to a bigger yield 
of better potatoes — at less 
cost! It’s so easy—just dip 
and plant! 
In actual farm tests, this quick 
dip treatment has given yield in¬ 
creases, averaging 13.6 per cent. 
It checks seed-piece decay, im¬ 
proves stands, and reduces or prevents crop damage from seed-borne Rhizoc- 
tonia and scab. Some gains have been reported as high as 25 per cent. 
Disease steals your potato profits by decreasing the yield and lowering the 
market value. A loss in yield of only 10 per cent frequently may represent 
the profit on your entire planting. Seed-rotting is another big loss in many 
sections. These two needless losses can be largely prevented by treating the 
seed, before planting, with Improved Semesan Bel potato dip. 
Treat only uncertified seed? No . . . treat certified or apparently disease-free 
seed, too. It may carry even a small trace of disease that the treatment will 
overcome. And the certified seed will rot just as quickly in cold, wet soils as 
any other seed—therefore treating it is a paying operation. 
COSTS SO LITTLE—2 to 3 CENTS PER BUSHEL 
Because it costs such a trifling sum, compared to everything else you spend 
to put out a potato crop ... is why you should apply Semesan Bel to all seed. 
35.4 MORE BUSHELS PER ACRE BY TREATING 
On six practical farms in Pennsylvania, Minnesota, Maine, Ohio and New 
York, careful records were kept—in actual field demonstrations, where seed 
potatoes were treated with Semesan Bel, and where they were not. . . . The 
average increase in yield on all six farms was exactly 35.4 bushels per acre 
—thus proving the wisdom of 
this quick one-minute dip. 
No question remains — it 
pays beyond all doubt to treat 
Seed Potatoes with improved 
Semesan Bel. . . . Prices: 4- 
ounce tin costs you 45 cents; 
1-pound tin, $1.50; 5-pound 
tin, $6.75; 25-pound pail, 
$31.00.
