BENEFITS OF 
New Improved SEMESAN JR. 
Seed corn treatment, although a comparatively new 
farm practice, is now recognized as one of the necessary 
operations in successful corn production. 
ITS PURPOSE —The purpose of treating field or sweet 
seed corn with New Improved Semesan Jr. is to de¬ 
stroy the root-rot organisms living on the seed and to 
protect it from decaying under unfavorable soil con¬ 
ditions. It usually increases stands and yields. It will 
not control corn smut, wire worms, grubs, crows, moles, 
gophers or similar pests. 
NEW LOW COST iy 2 c PER ACRE —One pound of 
New Improved Semesan Jr. treats 8 bushels of seed 
and costs one dollar. At the usual planting rate the cost 
of treatment per acre is 1 J^c. 
HOW IT IS USED — New Improved Semesan Jr. is 
a dust which is used at the rate of 2 ounces for each 
bushel of seed. After testing, culling, grading, and 
cleaning, the seed and New Improved Semesan Jr. 
are mixed together in a treater for 2 to 3 minutes, then 
the seed is ready to plant. 
PRACTICALLY FRICTIONLESS— 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. Seed treated with i t i s dropped by 
the planter just as uniformly and accurately as un¬ 
treated seed. It can’t cause any planter trouble. 
HOW IT WORKS— As soon as the seed is planted, 
New Improved Semesan Jr. throws around it a tiny, 
protecting cloud of gas or vapor. This vapor is harmless 
to the seed and seedling, but it helps to prevent the dis¬ 
ease germs (spores) on the seed and in the soil from at¬ 
tacking the germinating seed and seedling. It maintains 
this protecting cloud of vapor until the young plant is 
well started. No wonder it usually increases stands 
and yields! 
TREATING EQUIPMENT 
The only treating equipment required for small quan¬ 
tities of seed is a discarded 40-quart milk can, an old 
butter-churn or similar container. Larger quantities 
can be treated in a rotary drum such as illustrated below. 
This effective duster can be made from a 30-gallon oil drum at a 
cost of $2 to $5
