Results Are Promising

While the results so far secured
from busting with calcium arsenate
are very promising, the work is still
! in the experimental stage The ma
chinery for applying the dust has not
been perfected as it should be The
amount to apply per acre, the time Of
application, number of applications
and the interval between the applica-
tions will all have to be worked out
more completely than they are at
present.
Another of the questions that will
require much work is whether the
| calcium arsenate had better be used
alone or mixed with some carrier,
such as lime or sulphur or both. At
/ present it is apparently advisable to
use the straight calcium arsenate, ap-
plying it at the rate of to pounds
/ per acre, and make to applications,
at intervals of one week. The dust
/ ing should not be begun until at least
! 10 to Is per cent of the squares are
/ infested This should be determined
/ by actual count of at least 100 or
/ 200 squares in different sections Of
the field
| Anyone desiring to experiment with
busting for the control of the boil wee
vii this season should bear in mind
that high grade of calcium arsenate
must be used. 1t should conform to
the following specifications. 1t should
contain:
Not less than 400 Arsenic Pentox-
ide,
Not more than O75q5 water solu-
BILE Arsenic PentOXide,
Density not less than 80, or more
than 100 Gu in. per pound.
They have found that the calcium
arsenate must come up to this stand
ard in order to give satisfactory con-
troll of the weevil and not injure the
plants. Hence, anyone who purchases
calcium arsenete should determine
that it meets the above specifications,
Advice Is to Go Slow
The State EntomolQgist advises the
farmers to 60 slow with this work this
year and carry on only experimental
work on a small scale, using a hand
gun to apply the poison. 1t is diff
cult to secure calcium arsenate of the
proper specifications, and it is also
almost impossible to secure power ma
I chimes. By conducting the work on
small scale this year they can de-
termine for themselves whether it will
! pay to dust for the boil Weevil in
/ Georgia or not Dust the heaviest
! infested field and leave check plot
of one acre so that you can determine
when the cotton is gathered whether
you have controlled the weevil and in
creased the yield enough to pay for
the cost incurred
The same effective control Of the
boil weevil from busting may not be
same material and method of apply
ing are used Another important fac
| tor to be determined before the work
is conducted very extensively by the
average farmer, is whether enough in
crease in yield can be secured under
Georgia conditions to make a profit
by busting for the control of the
boil weevil.
The Board of Entomology will con
duct extensive experiments this sea
son to determine what methods and
materials will give the best results
in Georgia They are in hopes that
by another year some definite recon-
mendations can be made in regard to
controlling the boil weevG by busting
The machinery will also be tested out
this season and no doubt many i'm
provements made so that more effect
i've machines for applying the dust
may be secured.

weevil, and other insects, address A
