AGRICULTURAL COLLEGE
ISSUES SPRAYING CALENDAR
Formula for Fruit Trees and Full
Instructions as to How Ii Should
BE Applied.

The State Agricultural college al
Pullman has issued the new spraying
calendar, which has been received by
Orlando Beck. county fruit inspector. 1t
will be mailed to anyone by addressing
that instituti ion. The formulae given
for spraying fruit trees is as follows:
Bordeaux Mixture Bluestone, lbs i;
good lime, lbs; water 50 gallons.
Dissolve the bluestone by suspending
it i'll % gallons of water in barrel
Stake the lime in another vessel. adding
water slowly TO make % gallons of lime
milk. Pour this slowly into the blue
stone water. stirring constantly. Many
orchardists now only use lbs blucstone
to make the above solution.
If there is not enough lime in the
mixture it will burn the foliage To test
this, take n saucer full of the mixture
and add a few drops of a solution of
cyanide of potash tone ounce to p

pears, more lime must be added until
no change takes place when the test is
applied.
Double Strength-Use only half as
much water.
Arsenic of Lime with Soda-White
Arsenic l ID; sal soda (crystaD, 4 lbs;
water, gallon.
Boil the above ingredients for Is or 90
minutes when the arsenic should be dis.
solved, leaving only a little sediment.
The stock solution may be kept indcf
nitely, but should be labelled POISON.
TO prepare the spraying mixture, use
/ pounds of lime to 80 gallons of water.
Add to this one pint of the stock solu
ion, stir thoroughly, and the mixture
is ready for use. In using this formula
use great care. The pots and utensils
used in preparing the solution should
not be employed for other purposes. The
arsenic should be plainly labelled lest
it be mistaken for something else.
Sulphur-Lime Wash-Sulphur, ID;
Lime, ID; water gallons.
First slake The lime in the cooking vat
When slaked add the sulphur and enough
extra water SO that the mixture will
stir easily. Keep it we'll stirred till
boiling begins. After one hours boiling
the mixture should be completely dis
solved Except for impurities in the
lime) and of an amber color. Then add
the requisite amount of water, and the
mixture is ready to spray. 1t should be
poured into the spraying tank through
strainer At present it is customary
to keep the mixture boiling, and to
spray it hot. 1t is advantageous to use
Il small amount of water at first so that
the mixture may be more thoroughly
and quickly boiled.
Salt, which was formerly added to this
mixture, is wholly unnecessary. Ordi.
narily. the gallons of water should be
used, but if a gasoline sprayer is used
we commend the stronger wash, as such
7praycrs throw Il finer spray.
Kerosene Emulsion-Kerosene, . gal
Ions; Whale oil soap, tor qt soft soap
la-lb; water, / gallon.
Dissolve the soap in the water by boil.
ing. and add the suds boiling hot to the
kerosene, away from the fire. The mix.
ture is then to be agitated violently
preferably by pumping it back on itself
with a force pump. After four or five
minutes the mixture suddenly becomes
creamy in consistence. If well made
the cream will stand for a long time
without free oil rising to the surface
Unless otherwise stated, use l gallon OF
the emulsion to Is OF 20 gallons of water
in spraying.
Cupram-Copper carbonate, ounces
ammonia Ito test &c degrees Baume)
3 pints; water to make, 45 gallons.
Make a thin paste of the copper car.
Donate in a pint and a half of water
Add the ammonia slowly, the result be.
ing a clear, deep blue liquid, if the am.
monia is of proper strength. Pour this
into the barrel of water, and the solu.
ton is ready for use.
Whale Oil and Quassia-Quassia chips
s lbs; Whale oil soap, lbs.
Soak the chips twelve hours in eight
gallons of water. Dissolve the soap in
boiling water. Strain the quassia ex'
tract to remove the chips, and add the
soap solution. Stir thoroughly, and di.
lutte to make 100 gallons.
This solution is used almost exclu.
sively for the hop aphis. 1t is quite
as effective against other species of
aphis. The whale oil soap without quas
