MeSSrS. Editors 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

If the pest exists in your orchard resolve to
control it and save your trees. 1t Is needless to
cite that this pest is a very injurious one, and
that it reprOduceS very rapidly. IL winters as
partially mature insect and must be treated
when trees are in dormant state, from the
fact that an insectide cannot be applied when
trees are in foliage strong enough to kill the in
sect without ipjuring the tree. Weak solutions
are applied in summer to hold the pest in check
until winter, when full strength can be used
with deleterious effect on the scale. Treat
ment should be applied early this spring be-
fore the buds begin to swell.
The most efficient and inexpensive treatment
as yet employed is the lime, sulphur and salt
wash, and 1t is strongly urged that each orchard
ist who has this pest among his trees will apply
it during the latter part of this month or the
s,,lnSnr and salt wash are good fresh stone lime.

(which should have previously been mixed with
water), and keep well stirred. In short time
add the quantity of salt and continue the boil
ing for at least three-quarters of an hour, OF
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 burn

so gallons and strain through fine mesh strainer
into the spray barrel and apply warm: Hot or
cold water may be added to make up the guam
tity but hot water is preferable as the solution
will spray better through the pump.
This wash has proven wholly enective ali over
the State in controlling the San Jose scale. In
addition to being an excellent 1nsecticide 1t Is
stated to have q beneficial effect upon the ap-
pearing fungi. Especially Is 1t effective in con-
| trolling the peach-leaf curl.
1t is strongly urged again that all orchardists

infected trees, as it will not only prove bene-

Any further information as regards the lime

furious insects, will be gladly given by writing
