A Westinghouse condensing dehumidifier—the type 
we have found most effective. 
of dehumidifier seems preferable to the des- 
sicating type, as the latter produces consid- 
erable heat. 
WHAT ABOUT TEMPERATURE? A dry 
storage room can be made even more effec- 
tive by installing an air cooling unit. Sey- 
eral seedsmen in the South now have stor- 
age rooms that use both dehumidifiers and 
window-type air conditioners. 
Naturally, the storage room should be 
placed in the coolest part of the warehouse 
—usually the northeast corner—when pos- 
sible. 
According to Toole?, really good storage 
should have a relative humidity of not over 
45% at a temperature of 80° F. However, 
his experiments and our own show that vir- 
tually any reduction in temperature or hu- 
midity or both will help to some extent to 
preserve the germination of stored seed. 
We will be glad to consult with any of our 
customers on the planning of a seed storage 
room. If you contemplate building such a 
room, write to us for suggestions based on 
our own experiences and those of customers 
who have installed improved storage facili- 
ties.

HOW CAN INSECTS BE CONTROLLED? 
This subject is covered comprehensively in 
USDA Circular AMS-64 dated July 1955, 
“Protecting Stored Seed From Insect At- 
tack.”” We suggest that you write to the 
USDA Information Office, Washington 25, 
D. C., for a copy of this excellent reference. 
Generally, insect development in seed is re- 
tarded as temperature and humidity drop. 
Therefore, the conditions most desirable for 
preserving viability and vigor are also best 
for controlling grain insects. However, 
chemical controls are often required, and 
these are fully described in the circular 
mentioned above. 
As an important sidelight to the problem, 
hundreds of merchants and growers have 
solved their small seed storage problems 
with a special low cost premium package— 
the Keystone LIFEGARD tin can. For in- 
formation on this, see below.
