The rapid spread of the San Jose
scale in the eastern states has fully
demonstrated the necessity for a con-
tinued and greatly increased use OF
contact ms eticides in our fruit or
chards. As natural consequence of
the wide interest taken by experiment
stations, orchard owners, and others,
in finding ways and means for suppress
ing this insect, many private companies
havetaken up the manufacture of con-
centrated materials of various kinds,
to be used as sprays upon infested
trees. The processes of manufacture
of these sprays are secrets, protect
ed by patents, and are sold under sig
nificant trade names. At present
they are being advertised widely by
the agricultural press and in other
ways, and the fruit grower in look
ing about for spraying material is
likely to have his attention directed
to them Crude petroleum, and the
lime-sulphur sprays have been used
extensively against the scale for many
years in certain parts of the country,
but the proprietary sprays are OF
Comparatively recent appearance and
introduce a new element into the war
fare against this most serious orchard
enemy. Tests of these concentrated
mixtures have been made in several
states but the results have not al
ways been uniformly good The for
mula for preparing some of the mix
lures are evidently being improved
and new brands are constantly being
introduced With such an abundance
of material on the market, the selec-
ton of the most effective and econom-
ical spray becomes quite problem to
the orchardist who has to contend
with the San Jose scale. For the
purpose of obtaining information along
this line, which would be Of value to
the fruit growers, the Experiment Sta
ton made test of several of these
sprays in the winter 1866
The Spray Material Used.
In making the test the following
brands of concentrated scale destroy
ers were used at strength OF one
gallon to twenty gallons Of water ac-
cording to the directions of the man
Target Brand Scale Destroyer, man
ufactured by the American Horticul
tural Distributing Co, Martinsburg,
West Virginia. Scalecide, manufactur-
ed by B. G. Pratt Co., New York; Kill
o-scale. sold by Griffith G Turner. Bal
timore, and Horicum, manufactured
by Hammond's Paint and Slug Shot
Works, Fish-kill-on-H Hudson, New York
Horicum is a lime-sulphur prepare
ton and the others are oils SO treat
ed as to make them readily soluble in
any quantity of water. They are put
up in large or small packages to suit
the convenience of the user. The
price Of the materials named are as
follows: Target Brand Scale Destroy
err, so cents per gallon by the barrel;
per single gallon. $1,00. Scalecide, so
cents per gallon by the barrel; per
single gallon, Sl.OO. kll-o-Scale, $l.OO
per gallon by the barrel; per single
gallon, $3.50 Horicum, 50 cents per
gallon by the barred; per single gal
Ion, $f00
Orchard Used In Making the Test.
The trees selected for the expert
ment. were in young apple orchard
near Tablers, W. Va. and belonged
TO Hon. Alexander Clohan. On De-
ember IS, 1905, fifty trees were chosen
all more or less infested with the
San Jose scale. These trees were di-
vided into blocks OF ten each, after
