FIG. xx-A spRAYrn AT WORK


lilo. The curculio beetle lays its eggs
in the young fruit shortly after it sets.
In doing so 1t leaves a half moon
shaped scar. which is its trademark.
One of the surest ways of getting rid
of this insect Is to jar the beetles
! from the tree at this time.
| Spraying is also an effective remedy.
| The bordeaux-paris green mixture
may be used, but arsenate of lead is
better, since it is less liable to iniure
the leaves. 1t is applied at the rate of
three pounds to fifty gallons of water.
The spray should be applied just be.
fore the blossoms open, just after they
fall and again about fifteen days later.
Poisonous sprays should never be ap-
Piled to fruit trees while they are in
| blossom. 1t is not necessary in order
to destroy the insects and will kill
many of the honeybees, upon which
the blossoms are so dependent for pol
lination.
The insects that have been men
toned so far live by eating the leaves
and fruit and In doing so take up
enough of the poison to put al end to
their destructive work. There is an
other class of insects, however. for
which such remedies are not effective.
These are the sucking insects. of
which plant lice are the most common
examples. Insects of this kind feed
by drilling through the outer LAYER of
the leaf or bark and sucking the plant
juices They thus escape damage
from any poison which may be on the
surface.
To get rid of sucking insects some
substance which will kill by coming in
contact with them must be used.
There is nothing better for this pur
pose than kerosene emulsion. This is
made by dissolving half pound of
fo2p In gallon of boiling rainwater.
This mixture is then taken from the
stove and two gallons of kerosene add
eu. 1he compound should be churned
Violently for few moments by pump
ing 1t up with the spray pump and
back into the pail This causes the
oil TO mix thoroughly with the water
BEFORE using this original mixture is
diluted with six to ten parts of wa
ter.
a common insect affecting garden
crops and one that is hard to handle
Is the striped cucumber beetle. This
Is serious enemy of cucumbers
souashes, melons and other plants of
Ike nature. Spraying does little good |
ana is liable to injure the tender plants
as well. Where but a few hills arc
raised, covering them for the first |
TWO weeks with small box with mos (
quito bar stretched across the ton is n
good preventive measure. Another ef
1ective plan Is TO go over the natcb
In the morning while the dew is on
and the beetles cannot fly, knock them
10 the ground by giving the plant
slight blow and put drop of kerosene
on each one.
Where any of these crops are raised
On large scale the most efPaotivo
remedy Is the use of trap plants /"
rant the field to squashes a week or
ten DAYS before time to plant the main
crop. The beetles are especially fond
Oh squash plants and will gather ON
Ihem In large numbers as soon nc tbo,,
come up. just about the time the oth
y plants begin to peep through the
ground the squashes can be SPRAYED
with very strong kerosene emuIsion
