BOIL WEEv|l CONTROL IL
EARLY SUMMER
WeeviI Picking.

Clemson COlleSo, May - ue COl-
ton boil weevn requires a long time to
come from its winter quarters In the
spring and early summer. These pests
begin to emerge usually during the
latter part Of March and while nearly
all of them will be out by the first
week in June, yet there are stragglers
that will not come out until the first
week in July. They feed upon the
tender leaves and the tips Of the buds
until the squares begin to form.
Whenever weevils are present in no.
iiceable numbers on the young cot
ton, 1t will pay to 60 over the field
carefully once or twice and collect
these overwintered weevils from the
buds, says Prof. A. F. Conrad, entomo-
logist. This can be done most econom-
ically and effectively just before the
time with the utmost care, the ma
jority Of the weeviis may be gathered
before any eggs have been laid. The
weevils may be killed by crushing
them when caught or by putting them
IN a vessel containing water with &
fllm Of kerosene over It. The collec-
ton OF weevils before the squares are
formed, 1t is estimated, will not pay
where upon thorough search less than
50 weevils per acre are found: To
catch weevils from tie plants, the fol-
lowing method is generally used: One
hand is held horizontally under the
tip Of the plant so thet when this tip
is bent over with the other hand 1t
may be readily caught This method
is based on the fact that the Wseyil
plays possum" and will drop to the
ground like dead when disturbed. The
operator will soon learn this. A great
many weeyils will escape by dropping
to the ground so quickly that they are
not even noticed BY the collector.
Square Piekins.- e.
Where an attempt at square pick
iAe 10 contemplated, the following
should receive careful consideration.
First, collecting should be begun
about ten days after the frst bloom is
seen II the field. Second, unless the
work is done thoroughly it is not pro.
fitabls, and this means not only that
,uuares must be picked from the
ground, but also those that have dried
On the plants, as we'll Is those that
show by their unnatural pale or yel-
low color, or by fiaring, that they are
injured so that those squares hang
ing on the plants may not give the We
evil sufficient time to come out be-
fore tho next collection. This means
that collection should be made about
every fifth day. Fourth. the collec.
-tion of squares should be continued
for at least six weeks. Filth, the col
lection of squares is generally advised
during the first few weeks Of the
square forming period where weevils
have lived through the winter In large
numbers. Sixth, it must not be Tor
gotten that under boil weevil condi.
tons much depends upon cultivation
The chief object is to urge the growtf
and fruiting Of the plants as rapidly
rs possible. Seventh, it is estimated
that 1t will not pay to pick weevils OF
squares unless low priced labor is
available. Frequently this can be
secured by the employment Of women
and children who have an interest in
the crop.
Those who are planning to use the
calcium arsenate poisoning method
for controlling the boil weevil are d.

in the fewest words possible.
