ble powder to 100 gallons of water. 
For small quantities, add 24 ounce 
(approximately 16 level tablespoon- 
fuls) of a 50-percent powder or 114 
ounces (about 32 level tablespoon- 
fuls) of a 25-percent powder to 5 
gallons of water. Mix the DDT 
owder thoroughly with the water. 
DT is a poison and should be 
handled carefully in accordance 
with manufacturer’s directions. 
If harvested nuts are found to be 
infested with weevil eggs or larvae, 
these should be killed by immersing 
the nuts in water held at a constant 
temperature of 120° F. for 30 to 45 
minutes, depending on the size of 
the nuts. 
Japanese beetles feed on the flow- 
ers and leaves and often cause seri- 
ous injury to the trees. These 
beetles can be controlled by spray- 
ing with a mixture of 2 pounds of a 
50-percent or 4 pounds of a 25-per- 
cent DDT wettable powder to 100 
gallons of water. 
Certain bacteria and fungi may 
attack the nuts, causing them to 
spoil or decay. Spoilage is more 
common in the Southeast than else- 
where, perhaps partly because of

the higher temperatures and humid- 
ity that usually prevail there when 
the nuts are maturing. Nuts of the 
Kuling, Meiling, and Nanking va- 
rieties of the Chinese chestnut have 
good keeping qualities, and these 
varieties are recommended for or- 
chard planting in the South, where 
nut decay is a serious problem. 
Ornamentals 
Blight-resistant chestnut trees 
make beautiful shade trees for the 
lawn or farmyard. They have at- 
tractive form and foliage. Most 
people enjoy the sight of a chestnut 
tree full of catkins in the spring and 
early summer or loaded with nuts in 
the fall. Chestnuts should not be 
planted where the branches would 
eventually overhang a roof from 
which water is collected for a cis- 
tern; the flowers and leaves have a 
disagreeable effect on the taste, 
odor, and color of water. A few 
trees, in full sunlight, will produce 
an abundant supply of nuts for 
family use, and, if properly stored, 
these can be enjoyed throughout the 
winter.
