Ifo1troIIing The Apple Worm
:, came parts of the U. s., at a
10 . st from 50 to IS per cent
low We ss$ annIes are infested with what
q .. ' csn nno called The he. Apple 5s
5 .o -, and with those that have
Ho5 nad during the growing period
dfOp aronortion is even greater.
tn g5 G.O insect is the larva form of
lI rodlin Moth, which appears IN
l .ss SDring soon after the fruit has
Y. Y nd Il deposits its eggs either on
s ~ or young fruits.
'D o. sometime it was thought that
~ pogs were all deposited in the
W. .lnT Or blossom end of the apple,
!. S t.' the fact that when the eggs
t LItl. the worms made their way
into tbe apples at this point, but the
f e Is. a large per cent of the eggs
40 deposited upon the leaves.
After the worms have Matched
bor make their way to the calyx of
t5o fruit, in the meantime feeding
nnon the leaves and skin Of the
fruit
This is one of the insects for
mich fruit trees were first sprayed,
ond now that the life and history of
H. insect is so we'll understood it
has become a simple matter to con-
troI t BY means Of arsenate of lead,
Paris Green and other arsenicals.
The first spraying should be done
Immediately after the petals fall.
The secret of success in all spraying
. is thoroughness.
The first spraying should be so
thorough as to fill every calyx cup
with the poisonous solution.
. If the spraying is DELAYED much
more than a week, the calyx lobes
upon many varieties will close and
the fruits turn down, making it i'm
possible to deposit the poison within
the caIyx.
The fact that the ca yx lobes close,
and the flowers turn down serves
tohold the poison and thus makes it
impossible for the worms to eat into
the apples without getting a poison
Gus dose
The experienced fruit grower
thinks that his trees are sufficiently
sprayed when the work is not more
tllaIl nall completed.
! For this reason the best results are
usually obtained with the power
! outfit, although effectual work can
be done with the barrel outfit pro-
vIded sufficient muscle is used upon
the pump handle.
The best results cannot be obtain
edunIesS a uniform high pressure of
not less than one hundred pounds is
maintained because with this the
poison will be driven INTO the calyx
cup.
Whether using the hand pump or
we power outfit it is a good plan to
put as much on as is thought neces-
afy and then put on nearly as much |
more So as to be sure Of a thorough
job.
IN the valleys where the winds
@e prevalent, wnen the first appli-
S''lon Is put, spray with the wind is
possible as this will carry the
allst through the trees, and then
S"eA the wind is favorable spray
Us o'her side. If the wind does not
o Dsgome favorable spray anyhow
i"lner than leave the trees I'M
sprayed.
lAe frst spray should consist of
. 'vo pounds Of Arsenate of lead to so
gallons Of water.
7 there has been any trace Of
:, appe scab IN the orchard it is adj
''o.e 70 use the Bordeaux Mixture.
- - 4, @olch add two pounds of arsenate
ol \. to fifty gallons.
-. I ne weather is rainy and the
a o(a" mas been prevalent in the or
s s"aIa n about three weeks it is ad-
Of fa au. TO use about Il to 2 pounds
R !. a5Se&at4 Of lead to 81 gallons Of
o n.uSauz !. for a second spraying.
a. l. appllcation thoroughly done
