Sweet Potato Treatment Pays Too! 
Seed sweet potatoes carry on their surfa-ce the organ¬ 
isms that cause stem rot, black rot and scurf. These 
diseases take a heavy toll from your yields of market¬ 
able roots! 
As the stem rot and scurf are transmitted from the seed 
to the sprouts, and also from the soil of the seed bed to 
the sprouts, it pays to disinfect the seed potatoes before 
planting. The sprouts too should be disinfected after 
they are drawn and before transplanting. 
Carefully conducted tests in several states proved con¬ 
clusively that the Improved Semesan Bel treatment of 
seed potatoes and sprouts increases stands and yields. 
Add to your profit by dipping your seed sweet potatoes 
and the sprouts in Improved Semesan Bel.
