Seed Corn Treatment 
Facts 
F or many years, farmers have treated wheat and other 
grain seeds to control smut. The treatment of seed corn, 
however, is a comparatively new farm practise; and many 
corn growers are not yet entirely familiar with its purpose. 
What You May Expect 
New Improved Semesan Jr. usually will improve the 
stand and increase the yield of field and sweet corn. The 
average increase in yield in a large number of tests has 
been about 10%. Whether your increase will be 5 or 25% 
depends upon many factors, such as the quality of your 
seed, its freedom from disease, and the soil conditions at 
planting time. 
What You Should Not Expect 
New Improved Semesan Jr. will not control corn smut, 
w ire worms, and grubs. Neither will it prevent damage by 
gophers, ground squirrels, moles, crows, or similar pests. 
It is not designed for those purposes. 
Practically Friction-less 
Rub a pinch of New Improved Semesan Jr. between your 
thumb and finger, and note how smooth it is — practically 
friction-less, smooth as silk. Treated seed is dropped by 
the planter just as uniformly and accurately as untreated 
seed. And, of course, it can’t cause any planter trouble. 
A Tiny Cloud of Gas 
As soon as the seed is planted, New Improved Semesan 
Jr. jumps to its task, throwing around the seed a tiny, 
protecting cloud of gas or vapor. This vapor is harmless 
to the seed and seedling, but it helps to prevent the disease 
germs (spores) on the seed and in the soil from attacking 
the germinating seed and seedling. It maintains this pro¬ 
tecting cloud of vapor until the young plant is well started. 
No wonder it often increases stands and yields!
