SAN JOSE SCALE.
About Sprays and Spraying-Ditfcr-
cnt Mixtures Described.

Clal. ne season Is So lar auNdlCSu
that II one who wishes to spray
for San Jose scale must make prepa-
rations Immediately, because the
winter l~ime-sulphur wash, or my of
the other sprays used to kill scale,
are too strong to use on trees after
the buds have started. The wash
most com.Ionly used in this State is
the concentrated l~ime-sulphur wash.
This may be made at home accord
ing to n detailed formula furnished
by the Division of Entomology Of
Clemson College upon request. 1t is
not necessary to repeat 1T here be-
cause it has been printed in these
columns several times. With the
improvements in the commercial
washes, however, in recent years, as
we'll as the reduction in price, we
prefer to recommend the use Of the
commercial wash over the home
made wash. The commercial wash
is more uniform. 1t must be boil e
in mind, however, that in purchas-
ing such a wash it should be bought
from a house of reliable standing.
The winter wash at present costs 10
cents per gallon in lots of so gallons
OF over, SO that a so gallon barrel
of concentrated wash can be deliv-
cred at points in South Carolina for
between $40 and $11. These
washes are used at the rate Of one
gallon Of commercial wash to nine
gallons Of water. The water may be
rain water or we'll water and used
cold. This spray should be given
just rs soon as possible, as it cannot
be applied after the buds have start
ed, and in hat case it is practically
necessary to let the trees go %untreat-
ed as far as scale is concerned until
next fall, after the leaves have fallen.
In badly infested orchards where one
spray was applied last fall, it is we'll
to repeat it in February before the
buds start, and in applying the spray
it cannot be Over-emphasized that it
must be applied thoroughly and
every part OF the tree covered. 1t is
practically impossible to spray a
peach tree before it Is pruned. AS
n peach orchard requires attention
every winter in the way Of pruning,
this should be done before the wash
is applied.
The wash alone is not sufficient. 1t
must be applied with a proper equip
ment. For the spraying Of fruit
trees we discourage the use IF bucket
or knapsack pumps, AMI we also dis
courage the use OF small barrel
pumps. 1t is immGterial what shaped
pump one may prefer, but the fol-
lowing e%sSentia,s are necessary to a
good equipment in the way Of a bar
rel pump: A cylinder PA to 2h
inches in diameter and an air cham
Der having a capacity represented by
a tube 30 inches long and 3 inches
in diameter. This air chamber may
have almost IN kind of shape, but
in the terraced orchards Of South
Carolina it is well to purchase a
pump where the air chamber Is down
fin the barrel. This will prevent the
pump from being top-heavy, and it
cannot so easily be thrown off Of the
wagon when moving across terraces
or turning at the ends OF tho rows.
one should purchase % feet Of half
men @-ply hose, a leakleSs stop-cock
at the end Of the hose, an extension
rod OF desired length, usually six TO
eight feet for peach orchards, made
or one-rourth inch iron pipe with
threads made at each end, and an
angle nozzle which enables one to
spray, even in a breeze without get
ting into the way Of the spray. A
Sood barrel equipment without bar
rel costs about SIS. Any coal oil,
Whiskey or mOlasses barrel will DO
for a spray barrel on which these
pumps can be fitted, because most
pumps have the heads adjustable.
and for a very simple barrel ton an,
one writing to the Division Of Ento-
mology will receive an illustration
as to how this can be made. With
e pump there comes a paper disk
having a drawing showing exactly
now the hole Is to be cut to mount
the pump perfectly into the barrel.
The manufacturers generally charge
about $3.50 for the barrel.
