Prof. Murtfeldt, writing of this in
/ sect says:
The necessity of guarding against
I this insect and taking measures to
/ keep it in subsection cannot be too
strongly urged upon every grower of
fruit trees. whether in large CONNER
cial orchards or in the few trees that
the Vllager sets out in his back yard.
Like the codling moth il is a pest of
such wide dissemination that there is
reason to fear it will be always with
/ us" At present there seems TO be no
hope except in continual warfare
against it. Fortunately this can be
waged most effectively in winter dur
ing mild spells when the washes can
be applied without freezing and when
the operator can work in comfort.
Now that the leaves are off ii be-
hooVes every grower of a tree care
fully to scrutinize its tWigs and
branches to see whether there is any
of the gray scurf that indicates the
| presence of this pest.
There are many localities still free
from it and by combined vigilance and
proper precautions it may for years be
excluded from such spots. One Of
these precautions is to plant no trees
except from nurseries that have the
certificate Of the state entomologist of
absolute freedom from scale. Anoth
er is, if possible, TO ascertain the near
est point at which the scale prevails
and closely watch the trees fronting
/ tina. direction, as being most liable
to infection by means of the birds and
insects which are the means of con-
veyanCe in addition to, in some cases,
heavy gales of wind.
Tho minute 81 of this scale often
prevents it's discovery until it is thor
oughly established on, perhaps, a few
trees only, but if these are sprayed
with the two most approved remedies,
kerosene emulsion and the lime. salt
and sulphur wash, it may be kept from
spreading.
In making the oil emulsions ordina-
ry soft soap or a soft fish oil soap is
preferable to any brand of bar soap.
The best formula is as follows:
Two pounds soap, four gallons soft
water, eight gallons oil, weigh or
measure the ingredients exactly, pour
the oil into a barrel or tub at a dis
lance from the fire where the soap is
being dissolved and when the soap So
luton is boiling add ii to the oil and
use the force pump vigorously thor
oughly to combine the two into a thick.
creamy substance, which will remain
unchanged Tor weeks. 10 IIlS QudnllIy
of the emulsion add water, when ready
to spray, to make from forty to fifty
gallons-the former is not too strong
for winter treatment
In recent reports from several state
experiment stations the limesulphur-
salt wash has given the best results.
The formula for this is:
Thirty pounds unslaked lime, twenty
pounds sulphur, fifteen pounds salt
and sixty gallons water. The direc-
tions for preparing are thus given by
Prof. Wilmon Newell of Georgia:
place about one-fourth of the water
in an iron kettle of large size and
bring to a boil. Then add the lime and,
during the consequent violent boiling,
the sulphur previously mixed with wa
ter and keep the mixture we'll stirred.
Lastly put i'm the salt and continue
the boiling two hours. This wash is
very corrosive to brass and copper.
and pumps i'm which these metals are
used require careful washing with
clear water after each days spraying"
Iron is not injured by the wash. and
iron pumps with the Vermorel nozzle
are to be preferred when obtainable
For few trees a small knapsack
pump or tree syringe can be used in
making the application. Two treat
ments are recommended, one in De-
cember and another in February or
early March.
