INSPECTOR ADVISES
SPRAYING OF SHRUBS
BY Prof. W. II. Lawrence.

AhS pitoCICC VI oO many Sduly me-
elected, diseased and oftentimes par
italy dead fruit trees, standing in
vacant lots and in the lawns, has a
very depressing effect upon visitors
and prospective purchasers OF orchard
tracts. In fact it is not until one has
made a trip through some portion of
the valley and has actually viewed the
well kept orchards that he RECEIVERS
from the shock received in passing
along the streets of this city. Con-
current with the neglect of these trees
orchard pests and especially the San
Jose Scale has become very abundant
and have in many cases so badly in
jured trees and shrubs that it is advis-
able to destroy the plants. Now is the
time for the property owners to CO.
operate in destroying all useless and
diseased plant and to spray the ones
which they desire to save. In remov-
ing all plants, especially fruit trees.
it is advised to dig them out in order
to destroy the roots and prevent the
formation of suckers at a later date.
All the rubbish must be destroyed by
burning as soon as possible Green
apple wood will burn as readily as
when dry. Start a hot fire by using
some good dry kindling. Destroying
all plants useless for fruit or shade is
by far the easiest. cheapest and most
effectual method of cleaning up.
After the destruction of the undesir-
able plants attention should be directed
to the proper pruning and spraying of
the plants such as are worthy of a
place in the lawn, garden, or vacant
lot. Pruning should precede spraying.
The one consideration in pruning is to
so shape the plant that it is possible to
spray it, and spray effectively.
Since lime-sulphur wash has the con-
fined properties of both an insecticide
and fungicide, this material is the only
one recommended for early spring
spraying, unless the spraying is being
done to control specific trouble. The
winter strength Il part lime-sulpbur
to to 10 parts water) should be used
and the application made before the
buds begin to open. In case late
spraying becomes necessary there is
some danger of injury to the fruit and
foliage of some plants.
While spraying there are several
points to bear in mind: Use a pump
that will develop IT'S to 200 pounds of
pressure; begin spraying in the most
difficult places to reach; spray thor
oughly so that every surface is coated
and all the croches, checks and spaces
behind the buds are splashed full of
the spray. This can only be done
when an extension rod to feet long
with as per cent crook equipped with
a nozzle which will give a driving
spray is used. The Bordeaux nozzle is
the best type for this work. In spray
ing tall trees it is necessary to spray
from a tower, unless one climbs up in
the tree, in order that the upper sur
faces of limbs, buds and the angles
between the branches and stems may
be filled.
Since it will be necessary to spray a
majority of the plants in the city it is
suggested that all persons desiring the
advice of an inspector, do so. 1t is
hoped that all of the diseased fruit
trees and other plants infested with
pests will have been destroyed or thor
oughly sprayed within the next six
weeks. Later as the time permits a
careful inspection throughout the town
will be made and additional work
necessary to secure complete results
will be done.
The recommendations given below
by Prof. Lawrence as to spraying and
other remedies should not be followed
until the trees have begun to bud.

/. Pests controlled by methods
other than spraying: CROWN GALL
OR HAIRY ROOT. Do not plant
trees infested with this disease. You
will not make a success of the orchard
business if you do. FIRE BLIGHT.
Prune out all hold-over cankers. Cut
several inches below each canker.
Keep the pruning tools wet with cor
rosive sublimate Il part to 1000 parts
of water) also saturate every cut.
Burn all prunings at once.
2. Pests controlled by spraying.
Use power sprayers giving pressure
of $50 to 200 pounds. Splash the spray
beneath every flake of dead bark,
behind every bud and in the angles OF
every branch. Use an extension rod 8

crook equipped with Bordeaux nozzle.
Do not use a nozzle throwing mist
spray. Take plenty of time to do
thorough work. Thorough work gives
the results.
SAN JOSE SCALE. Spray infested
trees with winter strength lime-sulphur
before the buds open. Coat every
portion of the tree. Remember to
spray the upper side of each branch.
Drive the spray around the scales SO
that they are thoroughly saturated.
RED SPIDER. Scrape the trunks
of the trees to remove the scales OF
bark beneath which the spiders hiber-
nate. Remove the dirt around the
crown of each tree to depth of 4 to >
inches. Spray the crown and trunk
thoroughly with lime-sulphur. Also be
careful to fill the angles between the
large branches with spray. Red spiders
are only killed when thoroughly soaked
with the spray.
GREEN AND BROWN APHlS.
Coat the eggs thoroughly with lime
sulphur. Spraying while the buds are
swelling gives the best results.

ing with $3.50 Bordeaux mixture Is
