able. For small orchards it will be
found convenient to purchase these
materials rather than to cook the
lime-sulphur at home. When using
commercial products dilute as direct

Se1f-Boiled Lime-Su1phur. The self
boiled lime-sulphur is much weak
er. It's special use is for summer
spray for peaches.
The formula for self-bolled lime
sulphur follows:
Lime, fresh and unslaked, lbs;
! Sulphur, flowers or flour, lbs.
Wafer, so gallons.
Smaller quantities than given IN
this formula should not be used,
but the amounts may be changed
any other quantities larger than the
above when the same proportions
are adhered to.
Use a barrel that holds so gal
Ions. Place the lime in the, bottom
of the barrel Pour into the lime
enough hot water to start the slak-
ing. AS soon as the shaking starts,
pour in the sulphur which should
be previously mixed with enough
water to make it run. Keep adding
enough water to prevent the lime
from becoming dry but not enough
to cool off the shaking process. Per
nit this to continue for five min
utes, then Immediately fill the bar
rel with cold water.
Some practice is needed to make
the best self-boiled lime-sulphur. 1t
is not desirable to have a mixture
that is underheated, for then the
sulphur settles and is difficult to
use On the other hand, it is neces-
sary to stop the heating before the
lime and sulphur become too strong
solution. If reddish streaks ap-
pear through the mixture, the sui
nh1Ir has haln 0Ver-he4ted.
Bordeaux Mixture. This is fungi
eide Of exceptional value for gen.
eral use, although in late years it
has been supplanted by the sum-
mer strength lime-sulphur solution
for the apple scab and by the self
boiled lime-sulphur for peach spray
ing.
Bluestone Cooper sulphate) to
lbs.
Lime, fresh and unslaked. to 6
pounds.
Water, SO gallons.
Dissolve the bluestone in 25 gal
Ions of water. Since a solution of
bluestone is heavier than water, the
copper sulphate should be suspend
ed at the surface of the water,
deep enough to be covered. Stake
the lime and mix with 25 gallons
of water. Pour bluestone solution
and the lime solution at the same
large quantity of Bordeaux is need
ed, stock solutions can be made up,
using one pound of bluestone to a
gallon of water and the same ratio
with lime and water.
To improve the spreading and
sticking qualities of Bordeaux mix
ture it is advisable to dissolve from
two to three cakes of hard soap in
each fifty gallons.
For making small quantities use
q -
lime and 1 gallon of water.
Kerosene Emu1ion. Kerosene emul-
sion is especially effective in kill
ing plant lice on apples. 1t should
be made and used with the great
est care.
Water, gallon.
Hard, soft or whale soap, IL lb.
Kerosene, / at.
To get an emulsion the water
must be soft. Use rain water If
possible If the water is hard use
boraX to soften. Heat the water and
dissolve the soap we'll. Pour in the
kerosene and either churn with a
broad hoe or pump the mixture
through pump back into itself.
The mixture should be churned I'M
til the oil, upon standing, does not
separate from the water. This re-
quires twenty to thirty minutes. The
above formula will give a 20 per
cent emulsion. To get a 10 per cent
emulsion add 1 IA gallons of water;
an per cent, gallons; and a
per cent, 1-2 gallons. The 7 per
cent emulsion is the one to use on
trees in foliage.
