day intervals until four applica-
lions of calcium arsenate have |
been made.
In this manner, Dr. DeLoach |
claims, the weevils are practically
destroyed before the squares begin
! to form, and therefore the weeyilj
cannot destroy the first squares.
While a new crop of weevils is
being Matched out, the first squares
mature and the cotton thus maze is
safe from ravages Of the weevil.
In addition, there is the vast
reduction in numbers secured
through the early poisoning of the
weevil.
A field infested as few as
twenty-five weevils-a number SO
small as to usually escape detec-
ton even by the most keen-eyed of
inspectors have. easily $500
weevils within twenty days, unless
these first twenty-five are poison
ed, and the $500 will multiply
themselves thre hundred times,
within an even shorter time than
twenty days during the hot sea-
son that follows the first Matching
period, according to DR.. DeLoach
/ This illustrates the necessity for
| destroying the first weevils, or
rather the advantage to be secured
by their destruction, for all along
it has been recognized that the
sooner the weevil is poisoned the
less damage the insect is capable
of doing
As to picking up squares, DR..
DeLoach asserts this is most impor-
tant throughout the poisoning sea-
son. Between the time the frs
square begin to form and the end
of the first poisoning period,
twenty days later every square that
falls to the ground probably con
tains a grub that will hatch out into
a weevil unless it is destroyed, and
! Dr.. DeLoach believes all of these
should be picked up and burned.
Flowing under isn't certain |
method, he says, no uncertainty |
can be permitted in the fight on |
the boil weevil. If uncertainties |
are dealt in, he believes, the one
certain thing is that the weevil will |
destroy the cotton crop.
Nothing should be permitted to |
interfere with the poisoning oper-
ations," says DR.. DeLoach. This !
is more important even than chop
ping out cotton. If choice must
be made between chopping or
poisoning ones cotton, let the
chopping go" he says. And speak
ing along this line DR.. DeLoach
cited one or more instances where |
In farmers who ommitted choppirg
their cotton in order to get pois-
on into their plants succeeded in !
producing more than bale to an
acre, this experience being con
firmed by L. G. Council, who
was present and recalled having
read an authoritative article bear
ing upon the subject in which
similar experience was related.
Eight hours is enough time in
which to poison the weevil, and
with calm, dry weather over such
a period, DIR. DeLoach says the
weevil can be effectually poison
ed through the use of dry calcium
arensate. 1t makes no difference
whether the poison be applied dur
ing the day or night, in his opinion
the essential thing is to poison the
weevil, and if the poison covers
the cotton plants thoroughly, one
is very apt to secure 100 per cent
results through the dry calcium
arsenate poisoning method, he saws.
Whenever rain interferes with
poisoning, or descends within 81
hours in quantities sufficient to !
wash the poison from the plant
then the poisoning process should |
be repeated Immediately
As to the analysis of calcium
arsenate to be used. Dir. DeLoacb
said this is covered by Georgia
law.
Poison to be effective must con
tain at least 40 or cent arsenius
pent-oxide, with a filler of some |
sort of calcium properly ground
absorption by the weevl.
The law on this point, he ex-
planned, could properly be amend
ed to provide the fineness to |
which the calcium should be ground
and also so as to prescribe the exac,
filters that may be used in the
manufacture of calcium arsenate in
tended for sale for agricultural
uses
As is well known, white arsenic
is the active poisonous element in
all calcium arSenate OY neJ oac,
