buy poison. The demand was 90 great that the
supply Of Paris green and powdered arsenate Of
lead was soon exhausted.
RESULTS IN 1911 AT EXPERIMENT STATION.
Last year experiments were carried on to de-
termine the value Of poisoning for this insect. The
poison was applied twice August 10th and i30th.
The cotton that was poisoned averaged only 1414
pounds Of seed cotton per acre. The cotton that
was not poisoned averaged only 767 pounds per
acre.
PoISoNs TO USE.
The two poisons to use are Paris green and
powdered arsenate of lead. Paris green is an old
poison and is well known. It is more poisonous
than powdered arsenate of lead and one pound is
usually enough for an acre of cotton. It is likely
to burn the foliage if applied too strong. Each
pound should be mixed with at least two pounds of
-four to make it stick better and to get it more
evenly distributed over the plants. Last year the
persons in charge Of poisoning the cotton worms
at the Experiment Station thought the Paris green
was more satisfactory than the powdered arsenate
of lead. Experiments in other states have shown
that Paris green will materially check the fruiting
of the cotton and is therefore not recommended as
the powdered arsenate Of lead. The powdered ar
senate of lead is a new poison that rapidly replac-
ing Paris green as an insecticide. It does not in
lure the plants and it is therefore not necessary to
mix with flour or lime. It is necessary to apply at
least three pounds per acre. but there is no danger
Of getting it on too thick as there is with Paris
green.
HOW TO APPLY POISON.
The quickest method of applying the poison is
to dust it through sacks carried at the ends of a
or narrow strip of board by a man on a mule.
The poles should be at least 18 inches longer than
the rows are wide. The sacks should be attached
to the ends of the poles. Holes are bored through
the pole or board through which the poison is
poured in filling the sacks. These holes are closed
with shoppers when the bags are filled to prevent
the poison from being wasted, Several kinds of
cloth have been used for thefe bags: two or three
tkicknesses of cheese cloth makes a very satisfac
tory bag, s or. Oznaburg is sometime used, old
-four bags will probably do very we'll. The amount
Of poison that is used will depend upoh the tight
ness of the cloth and the force with which the pole
is Jared. Care should be taken not to apply too
much per acre. One man ought to poison at least
tel acres a day. We have reports of thirty acres
a day being poisoned per man.
WHAT TO DO NOW.
Be sure that enough poles and SACKS are ready
for immediate use. Be sure that you have enough
poison on hand to go over your entire crop. That
is for each acre of cotton you should have one
.'dv1d of Paris green or three pounds of arsenate
lAf]ad. If you are to use Paris green be sure that
XIX have plenty Of -four or lime on hand to mix
~ s--..saada definite arrangements to get a
frrsgsh supply Of poison. Order a new supply as
soon as you find that it is necessary to use the poi
son that is on hand. Keep on the constant lookout
for the worms. Do not poison until the worms APP
pear and then no time should be lost in applying
it. If rains wash the poison off fresh applications
should be made. Local dealers should have large
supplies on hand so as to supply the needs of the
customers. The greatest loss from this pest last
year was due to the fact that planters could not
get the poisons when needed.
