Boli Weevil Poisoning in South Car
olina in 1920.

culture and it will always be neces-
sary in boil weevil control.
What is the poison expected to do!
To safeguard the cotton crop in
favorable 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.. Coad says: 1T seems inadvis-
able to attempt poisoning on land
which Is not capable of making at
least half a bale Of cotton per acre
in the absence of weevil injury
Is poisoning recommended in South
Carolina in 1920?
It Is conservatively recommended
in those coast and near-coast coun-
ties where the weevil is entering on
its third or fourth year including the
year when it first appeared.
approximately what territory is
this?
Beaufort. Jasper, Hampton, Char
lesion, Colleton, Barnwell Allendale,
and Bamberg Counties. If the sea-
son is very favorable severe damage
may be expected in Orangeburg and
Calhoun Counties and also i'll Dor
chester, Berkeley. Williamsburg,
Georgetown and Horny Counties
where the weevil made its first ap-
pearance last season. The weeSil as
q rule does not become very serious
the season of its first appearance.
| In what sections is poisoning not
recommended in 1920?
In the middle, eastern and north
ern parts of the State, because the
injury in 1920 is not expected to be
sufficiently severe to warrant IT,
What is the poison recommended"
Calcium arsenate, also known as
cal-arsenate and arsenate of lime.
Where can calcium arsenate be
purchased?
From any reliable source; but it
should not be used until full assur-
ance has been obtained that it con-
forms 10 the Government specifica-
tions. The U. S. Government analy-
zes samples free. and instructions for
sending samples are furnished upon
request.
What kind of busting machine may
be used?
No busting machine is recommend
ed for South Carolina that has not
the approval of the U. s. Delta Lab
oratory, Tallulah, La. That labora-
tory has had the most experience ana
is in the best position to advise.
The three types of dusting ma

uable tool on the farm for dusting
poison on a small scale for potato
beetle and other leaf-eating insects,
is very laborious to operate for con-
tinuous period and its use on any
scale in boil weeyil poisoning is at
Itended with considerable difficulty.
THE power busters have proved un-
desirable and will probably be en-
itirely supplanted by the wheel trac-
ton machine. The wheel traction ma
lchine seems to be the most satisfac-
tory type.
When should poisoning begin and
when and how often repeated?
AS a starting point in this state in
1920, it is recommended that poison
ling begin when the infestation has
reached Is per cent or 20 per cent.
Poison three times, five days apart.
If necessary make further applica-
tions to hold infestation to 25 per
cent. The infestation count should
Be made according to the standard
method directions for which will be
sent upon request. Beginners will
require about seven pounds OF cal
lcium arsenate TO cover an acre, eX-
perienced men about five pounds.
Has the boil weevil poisoning meth
cd yet passed the experimental stage
in South Carolina?
No. Whoever poisons in South
Carolina in 1920 must remember
that he is experimenting, and should
bad results be secured he should not
become discouraged, because many
mistakes will undoubtedly be made.
After this season we will know more
about it.
What are the most important pre-
cautions to be observed in poisoning?
Poisoning should not be undertak-
ell in 1920 except on heavily infested
land which would produce hall pale
per acre in the entire absence Of wee
vii injury.
Before you use your calcium ar
senate be sure that it conforms to the
Government specifications.
Be sure that you have an approved
busting machine. Some dusting ma
chimes are not satisfactory for this
work.
Do not undertake more than you
are absolutely sure you can handle
thoroughly. Do not miss or handle
haphazardly a single step in the rec
concentrations or you may court ell
tire failure.
Where approved hand busting ma
chimes are used, it is suggested that
the beginner plan on five acres per
machine unless he has plenty of good
labor so that he can rotate several
good men On one machine.
