"Close spacing: The more stalks
on an acre of land working at the
| job of setting fruit, the greater will
| be the early or bottom crop. 1t is
over this part of the crop that the
farmer does not have to contend
with the weevi.
practical close spacing is three
to three and a half feet between
rows and eight to nine inches be-
tween hills in the row. Two stalks
to the hill is desired if the space be-
tween hills is greater. On land that
| grows very high stalks more room
| between rows and between hills is
| advised, four feet between rows and
twelve to fourteen inches between
hills being preferred.
"Cultivation: weekly cultivation
until bolls begin to form, then as
often as necessary to keep down
weeds and grass. Alternate middle
cultivation in July is preferred for
the purpose of reducing shedding.

Direct Attack on Weevil
"Boll weeyils pass the winter in
the adult form. When the winter is
over 95 per cent or more Of them
have frozen or starved. The sur
vivors are those that wintered i'm
dry, we'll protected places, such as
hay stacks, houses, stumps, grassy
terraces and ditch banks.
at is practical to kill the weevils
wintering in grass in the fence cor
ners, on ditch banks and in stumps
| by applying fire. But it is not ad-
visable to burn cotton stalks. They
should be turned under to improve
the soil. If any weevils are in old
| burs or unpicked locks they will be
plowed under and in their weak con-
dition will never emerge.
Kill weeVils before they lay eggs.
Until squares are formed on the cot
ton plants, the wintered-Over WeeVlls
have no place to lay eggs, and as a
until that time. The egg the weeVil

a worm, and when the worm begins
to feed inside the square, real dam
age begins.
Many Wintered-over Weevils that
come into the cotton fields early die
a. natural death before squares are
! formed, hence they have no chance
to lay eggs. 1t would, of course, not
pay to kill weevils that will die be-
fore they can do any harm.
The logical time then to poison
wintered-over weevils so as to kill
them before they lay eggs, is just
before squares form or before the
first squares are half developed.
Poisoning
early poison: One or two appli-
cations of calcium arsenate dust OF
liquid poison at that time is recon-
mended. If the dust poison is used
| it may be applied for this early
treatment with a dust bag by shak-
ing into the tops of the small plants
, one to two pounds per acre, or with
q machine choked down to put out
that amount. If liquid poison is pre-
| ferred, a home mixture of one pound
| of calcium arsenate, one gallon of
| syrup and one gallon of water thor
Oughly stirred may be mOpped on
the tops of the plants at the rate of
a gallon to a gallon and a half to
the acre.
authorities advise pre-square
poisoning if there seems to be about
| twenty weevils to the acre. If, how
| ever, a farmer can not take time to
make close investigation, but sees
| signs of weevils, it will be wise for
| him to apply the poison. If there
are no signs of weevils after the
first application of the regular pre-
square poison, it will not be neces-
sarv to repeat it. But if a second
application is needed, it should be
| put on about five days after the
first.
Gather Fallen Squares
Gather infested squares after the
pre.square poisoning described; II
will be- useless to apply poison until
time for new weevils to hatch out,
for if any of the wintered-over
weevils escaped poison and succeed
ed in laying eggs in squares they
soon die natural death. so that 1T
is almost impossible to find weevils
! in the cotton field between the time
cotton begins squaring freely and
the time blooms begin to appear.
When blooms begin to appear the
! eggs laid in the first squares will

During the time between the pre-
! square poisoning and blooming OF
! cotton it is advised that the farmer
| gather and destroy the infested
( squares. These contain the eggs or
! immature WeeVils.
Once a week for three weeks
/ ahead of the plow, the infested
| squares should be collected whether
| they are on the ground or are still
attached to the stalk Very few in
| tested squares will be found during
| this period, but they are easily de
( tected and by looking sharp very
! few need escape notice.
