LIME, SULPHUR AND
SALT SPRAY IS BEST

Below will be found an article call
ing attention to the necessity of
spraying either for or to prevent San
Jose scale and fungus diseases of
fruit trees. The article Is by Prof.
Cordeley, who calls attention TO the
fact that in recent experiments car
ried ON by the Oregon Experiment
Station, the lime, sulphur and salt
compound has proved more efiica-
cious than the lime. sulphur COM
pound to fully justify the use Of the
salt. In this connection it is well to
remember that the lime, sulphur and
salt compound was originated in Cali
fornia and was the result of great
amount of very thorough experiment
tai work. At the experiment stations
in Idaho aud Eastern Washington the
addition of the salt has not apparent
ly added to the effectiveness of the
spray. The climatic conditions at
Pullman, Wash. and Moscow, Idaho,
are quite different in winter from
those OF Western Oregon. We have
therefore always recommended the use
of the salt in the compound for the
region west Of the Cascades, where
the rainy winters make it necessary
that the compound be such as will
stick to the trees 1t is believed that
che salt makes the lime sulphur, salt
compound better than lime e-suIphur
compound At any rate for the pres
ent the evidence Is strongly in favor
of using the old reliable formula west
OF the Cascades. This is the very best
time Of the year to apply this spray.
1t Is the nearest to cuTe-all spray of
any known. As Prof. Cordley says,
it kills the San Jose scale, destroys
such germs of fungus diseases as it
reaches, cleans the moss off the trees
and kills to a large extent the woolly
aphis, and other insect pests which
may be on the trees.
In the second edition of lnsecti-
cides and Fungicides, by Prof. Cord
ley, just issued by the Oregon Exper-
iment Station, what is known as the
"Oregon formula" il recommended
as the best for this climate. This re-
quires.
Quick lime-50 pounds.
Sulphur--50 pounds
Salt-25 to 50 pounds
"Slake the lime thoroughly, add the
sulphur, cover with water and boil
briskly for at least an hour. Then
add the salt and boil Is or 20 minutes
Longer, or until the mixture is deep
blood. red color. Add water to make
l50 gallons. Apply with considerable
force through coarse nozzle while
still warm"
The reason the spray should be ap-
piled while still warm is that 1t is
hard to make it work when it gets
cool. 1t is not desirable to use it
boiling hot, as il then Injuries the
hose. Dunne's solid spray is made
according to the above formula and
should also be applied warm. lnspec-
tor Reid says that he has found that
the Dunno sold spray is effective
when properly applied.
1t should be remembered that the
lime, sulphur and salt spray applied
before the trees blossom will In most
seasons prevent the curl leaf Of the
peach. 1t also takes the place of
spraying with Bordeaux mixture be-
fore the blossoms open on apple and
pear trees for the prevention of fcab.
The scab is what makes blotcbes and
hard, cracked places on the fruit and
one of the causes of black spots on
the leaves of apples and pears.
President Fremont Wood of the
Idaho State Horticultural association
called attention to the fact that on
October IL, 1904, 100 boxes of pears,
grown and shipped by H. g. Myers Of
Boise, Idaho, sold in New York for
1872 so, or an average of 1872 per box,
thus surprising the remarkable high
price of Sc. So per box obtained for a
carload of Southern Oregon pears.
