WEEVIL POISONING
IN SOUTH CAROLINA
WILL RAPIDLY DEVELOP INTO A
VERY IMPORTANT FACTOR.
In Experimental Stage.
Conservatively Recommended In
Coast and Near Coast
Counties This Year.
In Experimental Stage.

Clemson College, May 15.-In view
of the great interest in the possibili-
ties of calcium-arsenate poisoning to
reduce boil weevil damage, especially
in the lower half of the state, Prof.
A. F. Conrad, entomologist for the
state crop pest commission, has pre-
pared the following list of timely
questions and brief answers:
Do experiments so far conducted
indicate the successful developemnt
of boil weevil poisoning?
Present indications are that boil
weevil poisoning will rapidly develop
into a very important factor in boil
weevil control in heavily infested
fields.
Is it expected that boil weevil pois-
oning will take the place of diversi-
fed agriculture in boil Weevil con-
troll?
Soil building will continue as the
fundamental operation in South Caro-
lima agriculture and it will always be
necessary in boil weevil control.
What is the poison expected to do?
To safeguard the cotton crop in ia
vorable weevil seasons against ruin
Gus damage, just as orchard sprays
safeguard the crop against insects
and diseases, but do not take the
place of orchard culture.
May poisoning be expected to be
profitable on poor soils?
Mr.. Conrad says: 1T seems mad
visable to attempt poisoning on land
which is not capable of making at
least half bale OF cottor per acre
in the absence of weevil injury
Is poisoning recommended in South
Carolina in 1920?
1t is conservatively recommended in
those coast and near-coast counties
where the weevil is entering on its
third or fourth year, including the
year when it first appeared.
Territory is named.
Approximately what territory is
this?
Beaufort, Jasper, Hampton, Char
lesion, Colleton, Barnwell, Allendale
and 'Bamberg counties. If the season
is very favorable severe damage may
be expected in Orangeburg and CAL
houn counties and also in Dorchester,
Berkeley, Williamsburg, Georgetown
and Horny counties where the Weevil
made it's first appearance last season,
the weevil as a rule does not be-
come very serious the year following
the season of it's first appearance.
In what sections is poisoning not
recommended in 1920?
In the middle, eastern and northern
parts of the state, because the injury
in 1920 is not expected to be sufti-
ciently severe to worrant poisoning
What is the poison recommended?
ed?
Calcium arsenate, also known as
calarsenate and arsenate Of lime.
Where can calcium arsenate be pur-
chased?
From any reliable source; but it
should not be used until full assur-
ance has been obtained that it con-
forms to the government specifica-
tions. The United States government
analysis samples free, and instruc-
tfons for sending samples are furnish
ed upon request.
What kind of dusting machine
may be used.
No dusting machine is recommend
ed for South Carolina that has not
the approval of the United States
Delta Laboratory, Tallulah, La. That
laboratory has had the most expert
ence and is in the best position to ad-
wise. The three types of busting ma
chimes are hand busters, wheel trac-
ton or cart busters, and power dust
ers. The hand duster, while a valu-
able tool on the farm for dusting pois-
on a small scale for potato beetle and
other leaf-eating insects, is very la
borious to operate for a continuous
period and its use on any scale in boil
weevil poisoning is attended with con-
siderable difficulty. The power dust
ers have proved undesirable and will
probably be entirely supplanted by
the wheel traction machine. The
wheel traction machine seems to to be
the most satisfactory type.
When Poisoning Should Begin.
When should poisoning begin and
when and how often should it be re-
peated?
