San Jose Scale
An Earnest Appeal To The Appar
emily Negligent Orchardlsts
of Our State,

The season is at hand when every orchardist
must give his trees attention. Go among your
trees and examine them closely to ascertain
whether they are infested with San Jose scale.
If you cannot determine this fact send twigs
to the State Entomologist, College Park. Md.
and he will determine it for you free of charge.
Ifthe pest exist in your orchard resolve to con-
troll it and your trees. It needless to cite
that this pest is very injurious one, and 1t re-
produces very rapidly. It winters as partially
mature insect and must be treated when trees are
in dormant state, from the fact that an insecti
eide cannot be applied when trees are in foliage
strong enough to kill the insect without ipjuring
the tree. Weak solutions are applied in summer
to hold the pest in the check until winter when
full strength can be used with deleterious effect
on the scale. Treatment should be applied early
this spring before the buds begin to swell.
The most efficient and inexpensive treatment as
yet employed is the lime. sulphur and salt wash,
and it is strongly urged that each orchardist who
has this pest among his trees, will apply IL during
the later part of February or the first of March.
The materials needed for making the lime,
sulphur and salt wash are, good fresh stone lime
flowers of sulphur and common salt In the follow.
ing proportions: Fresh stone lime, 80 pounds;
Flowers of sulphur. 15 pounds Common salt, IL
pounds; Water to make so gallons.
The amount of lime may be reduced to 20
pounds if one desires, as 1t is stated that it is
equally as effective.
Method of making: Place Is to 20 gallons of
water in iron kettle, boiler or barrel the later
In using steaml 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) keep we'll
stirred. In short time add the amount of salt
and continue the boiling for at least "a of An hour
or until all the sulphur has been dissolved. and
you have an amber colored solution. 1t may be
necessary to add water from time to time to make
up for evaporation and to prevent burning. When
boiled sufficiently add water to make so gallons
and strain through mesh strainer 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 better
through the pump.
This wash has provenwholly effective all over
the State in controlling the San Jose scale; and
In addition to being an excellent insecticide. 1t
is stated to have beneficial effect upon the
early appearing 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
rs it will not only prove benefit to themselves
but also to their neighbors in preventing the
further spread of the insect 1t may be mention
ed 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
