SPRAY FOR SAN JOSE SCALE
Description and Method Of Treating
This Orchard Pest.

One OF the most dangerous Of the
fruit tree pests in this state is the
San Jose scale 1t can be identified
by the tiny scales slightly raised in
the middle which are seen on the
branches Mr. w H. Chandler Of the
Department of Horticulture at the
University Of Missouri, gives the fol.
lowing description OF the pest and
the method Of treating It;
The insect OF the San Jose scale
inserts It's boak into the bark OF the
tree and cxcrctcs scale covering its
body. 1t mu!tiplies rapidly and may
completely cover the bark Of the
limbs in place When the limbs be.
come oncrusted with them, the tree
is likely to die.
San Jose scale can be readily con.
trolled by spraying with boiled lime.
sulphur or some of the misCible oils
Directions are given below for the
preparation of the various sprays.
The best time to spray is in the fall
soon after the leaves are of, or In
the spring when the trees are still
dormant. Spraying in mid-winter is
rot only very disagreeable, but has
been found to be less effective.
This insect attacks apple, peach,
currant, pear and many other com.
mon fruits Every orchardist who Is
interested in the welfare of the state
should strive to kill out this pest and

that are badly infested should be cut
down and burned. Nursery stock is
not likely to be infested, but II It
| should happen to be found So II
| should be burned also. The trees will
| be Of very little use II they are bad,
| ly infested
One of the treatments for San Jose
! scale Is a spray OF miscible oil. There
| are various kinds on the market
! They are oils so treated that they
will mix with any proportion Of wa
ter, generally giving white emul.
sion. They should not be used unless
| they cmulsify. Sometimes. under Ger.
tain conditions, the oil comes to the
top when they are put into water in.
stead OF making an emulsion. In this
condition 1t should not be used. I'm.
less the oil has been frozen often,
the company should be asked to make
II good.
Another effective spray for the San
Jose scale is the lime-sulphur which
can be made at home. It requires Il
pounds OF lime, Is pounds of sulphur
and 80 gallons of water. Shake the
lime TO thin, fine paste, add water
to the sulphur until It becomes a
paste, mix with the lime and stir
the entire mass until all are well
mixed. Add sufficient water to make
up to a thin white wash. Bring the
mass to the boiling Point and allow
TO boil vigorously for IS minutes. Add
enough water to bring up to fifty gal
Ions and strain as Il Ia poured into
the spray tank. Apply while hot. The
color will have changed in the boiling
to a deep yellowish or brownIsh
green. This mixture can not be used
while the foliage is on tho trees.
The appearance OF the home
grounds around the farm house should
be n matter OF more interest. The
problem OF keeping the boys at home
on the farm, which is a great problem
everywhere today. would not be sc
great II the surroundings were made
more pleasant There is very little
time or work involved in keeping Q
neat lawn about the house. 1t Is no
difficult nor expensive to set few
plots OF shrubbery In appropriate
places around the grounds. But the
results will be very striking. "Tht
chickens can not be allowed the range
OF the front yard" says Professor
Howard OF the University of Missouri
IF the bluegrass is kept in good con
dltion. But the chickens can fint
plenty OF other range. and the yart
