An Earnest Appeal to the APP
parently Negligent Orchardists
of Our State.

State EntOmOlOglSt, has sent out the IOl.
lowing circular calling attention to the
presence of the San Jose scale in the
orchards Of the State:
The season is at hand when every Or
chardist must give his trees attention. Go
among your trees and examine them close
ly to ascertain whether they are infested
with San Jose scale. If you cannot de-
termine this fact send twigs to the State
Entomologist, College Park. Md, and he
will determine it for you free of Charge.
If the pest exists in your orchard re,
solve to control it and save your trees.
1t is needless to cite that this pest is a
very injurious one, and that it reproduces
very rapidly. 1t winters as partially
mature insect and must be treated when
trees are in a dormant state, from the
facts that an insecticide cannot be ap.
piled when trees are ia foliage strong
enough to kill the insect without injuring
the tree. Weak solutions are applied in
summer to hold the pest in check until
winter, when full strength can be used
with a deleterious effect on the scale.
Treatment should be applied early this
spring before the buds begin to swell.
The most efficient anddnexpensive treat
ment as yet employed is the lime, sulphur
and salt wash, and it is strongly urged that
each orchardist who has this pes. among
his trees, will apply it during the later
part of this month or the first Of next.
The materials needed for making the
lime, sulphur and salt wash are good
fresh stone lime, flowers Of sulphur and
common salt in the following propro-
tions: Fresh stone lime, 80 pounds;
flowers of sulphur, Is pounds; common
salt, IL pounds; water to make so gallons.
The amount Of lime may be reduced to
20 pounds II one desires, as it is stated
that it is equally as effective.
Method of making: Place about Is to
20 gallons Of water In an iron kettle,
boiler or barrel, (the later is using steam).
and bring to boil. When the boiling
point is reached, add the amount Of un-
Stacked lime and during the consequent
violent boiling add the sulphur, (Which
should have previously been mixed with
water) and keep well stirred. In short
time add the amount of salt and con-
tinue the boiling for at least of an hour
or until all the sulphur has been dissolv-
ed and you have an amber colored solu
ton. 1t may be necessary to add water
from time to time to make up for evapora
ton and to prevent burning. When boil
ed sufficiently add water to make so gal
ions aud strain through a fine mesh
straincr into the spray barrel and apply
warm. Hot or cold water may be added
to make up the amount but hot water is
preferable as the solution will spray bet.
ter through the pump.
This wash has proven wholly effective
all over the State in controlling the San
Jose scale; and in addition to being an
excellent insecticide, it is stated to have
beneficial effect upon the early appear
ing fungi. Especially is it effective in
controlling the peach leaf curl.
1t is strongly urged again that all
OrchardistS who have the San Jose scale
to combat, treat the infested trees as it
will not only prove benefit to them
selves but also to their neighbor in pre-
venting the further spread Of the insect.
1t may be mentioned in this connection
that our law requires that all infestations
should be treated.
Any further information as regards the
lime, sulphur and salt wash and also as
to the means of controlling the ravages
of this or other injurious insects, will be
gladly given by writing the State Ento-
mologist, College Park, Md.
