LIME, SALT AND SULPHUR.

For San Jose Scale Will Be Made as
Summer Treatment.
The need of an effective remedy for
the San Jose scale for summer use
has long been felt and although many
substances have been tried, nothing
has given anything like satisfaction.
For the past two years l have been
experimenting with the lime, sulphur
and salt wash as a winter treatment
for scale and the results have been
quite satisfactory as set forth in bull
letins and 3 of the Georgia State
Board Of Entomology.
During the present season 1 am max
Ing careful tests with this prepare
ton as a summer treatment for scale
and SO far the results have been very
encouraging. While the mature in
sects are not Immediately killed by
applications of this wash the breed
ing is not only quickly checked but
the young perish soon after they is
sue. The presence of the wash pre-
vents the young insects from establish
ing themselves and they are either
killed by the caustic action Of the
substance or perish from lack of food
Just what takes place is not yet well
understood, but the fact remains that
the young die and the parent insects
soon follow their example. And that
Is just what is desired. Instead of
increasing at an incredible ratio, as
on untreated trees, the number of
scales dwindle in the presence of this
wash until the trees become compare
lively clean.
1t should not be understood, how
ever that this means eradication. At
present it seems that no wash can be
SO thoroughly applied as to complete
ly destroy this pest The object is to
control and not to eradicate.
Application Of the Wash.
The principal difficulty in the way
Of applying summer washes is the
presence Of the foliage which is likely
to be injured by preparations Of suf-
fcient strength to be effective against
the San Jose scale. A thorough spray
ing Of tree is, therefore, not prac-
teal and the application must be made
by hand, The trunk and larger limbs
can be thoroughly painted by means
of brush or cloth mop and on young
trees, where the treatment is most
needed, the application can be extended
to within few inches of the tips of
the twigs This may seem impracti-
cal, but in the tests l found it not
difficult to quite thoroughly coat four
year old peach trees. In our CONNER
cial peach orchards the trees are
headed low and the limbs are in easy
reach.
A spray pump can be used to apply
the wash to the trunk and the lower
portion Of the limbs and in this man.
ner large orchard can be gone over.
However, the pump should be followed
by the brush in order to extend the
application higher up the limbs. Con-
tact of the wash with the foliage
should be avoided, although the de.
struction of some leaves will neces.
sarily result.
The time to make the application is
when living scales are found on the
trees. The San Jose scale will be
breeding quite rapidly during the
month of May, and an application dur
ing this month would effectively check
It's progress. AS a general statement,
I would say that the greatest benefit
from any one application might be
expected in August or soon after the
fruit crop is harvested. During the
fall months the accumulation Of scale
Is greatest, as Is also the consequent
damage to the trees.
This treatment is especially recon.
mended for application to badly infest.
ed trees likely to die If left untreated
until winter washes can be applied,
and for family orchards.
Preparation of the Wash.
The same formula, but with greater
dilution, as used for winter work, has
been found satisfactory for summer
applications with the brush. This
formula may be stated as follows:
Lime (unslaled) 80 lbs.
Sulphur (ground) .20fbs e.
Salt NEUTRALITY-SUSPICIOUS.. .15tbs.
Water to make 100 gals.
For winter work only 60 gallons OF
water are used with this formula, but
in the summer tests it was found that
a much weaker solution gave salts.
