emulsion must be applied with a spray

ihe plant and the application is also
moi as thorough as when a regular
spayer Is used. Spray pumps throw
ile emulsion in such a fine. Goggy mist
.at Il penetrates INFO hooks, corners
and creyices which would not be
reached with a sprinkler The appii-
tailon must also be so thorough as to
reach the individual insects. for they
arc only killed when 1t comes into ac-
mal contact with their bodies.
The directions for preparing the
emulsion are as follows:
Shave one-half pound cf laundry
soap into thin pieces in one gallon Of
water and bring to boiling heat on
stove to dissolve the soap, Then re-
nave The soap water from the Are and
pour in two gallons Of Kerosene ana
churn the whole together violently I'm.
ii thoroughly mixed. This is best
done by pumping it through the pump
and back into itself again. This gives
ihne gallons of emulsion. which is SIX
G.siy per cent. OIL but as this is too
strong for most uses, it may be diluted
by this table:
To get ten per cent. oil add seven
teen gallons water.
To get fifteen per cent. oil add ten
and half gallons water.
To get twenty per cent oil add seven
stllOns water.
TO get twenty-five per cent oil add
five gallons water.
To get thirty per cent oil add four
gallons water.
To get forty per cent oil add two gal
Ions water.
TO get ffy per cent. oil add one gal
lon water.
The emulsion is not a poison and does
rot kill the insects by being eaten, like
Paris green. 1t is only fatal to those
insects that are wetted by the appli-
cation, so that great thoroughness is
needed in making the application, SO
that every individual will be touched.
On the other hand, only enough must
he applied to thoroughly wet the in
sects, and the emulsion must not run
down the plant and in at the roots.
That is why regular spray pump is
50 necessary, in order to make the APP
pllcatlOn so thoroughly as to reach all
the insects without an excess, which
would hurt the plants.
Some Of the more common trouble
some insects for which the kerosene
emulsion may. be used are;
Cotton Louse-Spray with fifteen per
cent. emulsion as soon as they appear
and before they get scattered through
out the field.
Rose Louse-Spray with fifteen per
cent. emulsion when they appear.
Cabbage Louise. Same, before leaves
get curled.
Green Apple Louse-same as cab.
bage louise.
Woody Aphis Of Apple--Use fifteen
rer cent, or twenty-five per cent in
winter.
Black Aphls Of Peach and Plum
Spray with fifteen per cent. before
leaves get curled.
Pea Louise. or Aphis-Use emulsion
Mt ten or fifteen per cent. or tobacco
dust. We have not yet fully settled
this question,
