Applying Calcium Arsenate to Cotto
BY DIR. ANDREW M. SOULE

Applying Calcium Arsenate to Cotton
L. j. S., Commerce, Ga, writes:
What Is the most economical
way of applying calcium arsenate
for one-horse tenants that have
to furnish everything for them
selves? How does the soy bean
compare with peas as a forage
and fertilizer?
The most economical way for you
to employ the calcium arsenate
which you have purchased in pow
dered form is as follows: Secure an
old gallon fruit can CT sSsGe other
such cclltai1er and hasten IT to
stick of proper length. Punch hole
not too large in the bottom OF the
can. Then. tie securely over the bot
tom of it d piece of fine cheese clotn'
AS soon as the Weevil makes It's ,ap-
pearance, begin busting. A very
small application should be eHectlVe
as you only need to get llttle OF
the calcium arsenate i'm the BUD Oh
the plant. 1t is to this part OF the
cotton plant that he goes upon
emerging from his winter quarters
You should have no trouble IN locat-
ing him at that time. When the cot
ton begins to square. and the WeeVl
shows I'D in considerable numbers,
dust again. For this purpose, we De-
lieye if would be best to have mana
machine. 1t will probably cost you
$40 or SIS to buy it, and 1t Will 90
the work satisfactorily. If you take
good care of it, it should last for
more than one season. In using cal
cium arsenate, spray it on the plants
about three times at intervals OF
three to four days. This should help
to eliminate one generation OF
weevils. You may have to make
later spraying when a new crop
matches out. Ordinarily, three APP
plications should go far toward con-
trolling this pest. In some seasons,
YOU may have to make as many as
five applications. Rain is one OF the
difficulties with which we have to
contend in the use of calcium arsen-
ate spray. Remember, the spray
should be put OH when the dew is
on the plant and on a relatively quiet
day. The finer the spray of dust, the
better.
The soy bean does very well in
north Georgia. There are a good
MANY varieties which can be grown
with success in this section OF the
state. We believe you will find the
Laredo the best for forage and grain.
Next will be the O-too-tan, though 1t
is a long-season variety and prob
ably a little better adapted for
growth in south Georgia on that
account. The Biloxi is also a good
strain. We have had good results
with the Haberlandt. For grain
growing alone, the Mammoth yell
low is among the best varieties. Soy
beans should be planted in drills
about three feet apart and should be
fortified with a formula containing
10 per cent phosphoric acid and
per cent potash. Use from two to
three hundred pounds of such mix
ture-at the time the seed is put
down. The Laredo soy bean SEED
are very small. Hence small guam
tity of them will be sufficient to
plant a relatively large area. The
hay obtained from this variety is
very fine in quality.
Controlling Smut in the Corn Field
T. 10. T., Nicholson, Ga,
writes: Please give me torm'
ula for treating seed corn to pre-
vent the growth of smut.
One of the few smuts attacking
cereals for which no specific method
of control has been discovered is the
corn smut. A great many methods
looking toward it's control have been
tried out, such as disinfecting the
seed, but all of them have failed.
This is due to the fact that the para
site which produces corn smut lives
through the winter in the soil or in
the manure rather than on the seed
itself. During the growing season,
the germs of this disease may be car
ried by the wind from one area of
growing corn to another. When they
fall upon the leaves or tender parts
of young corn plants, they develop
and produce the disease known as
corn smut. The most practicable
method of combating it is to go
through the field from time to time
and cut out and burn the infected
stalks. A rotation Of crops is advis-
able as the continuous cultivation of
corn on the same land tends to in
tensify the losses from this disease.
