ing. A little wind may be an advantage,
but q high wind wastes material and
renderes it difficult to do a good job
However, when time is very limited. one
must 90 on in spite of the wind and do
the best he can increasing the pressure,
( if possible. If rain comes before the
solution had dried, it will probably wash
it all or nearly all off If the solution

In spraying for scale problem is much
the same in both peach anda apple orchards.
The idea is to apply a solution which
will penetrate through or under the wadly
covering which protects the delicate body
/ OF the insect and kill the scale Lime
sulphur solution does this by virtue of
Its causticity; the oil mixtures do it by
reasons of their penetrating properties.
Men have not yet agreed as to which is
best TO use
1t is said that lnjudiciOus use OF the
su phur does not iujure tine trees. Either
may do serious harm if the application
be DELAYED until the buds have opened in
spring. The writer has seen peach trees
scotched a. by fire. and limbs killed back
to one half inch diameter bv spraying for
scale after the blossoms had opened. I'll
is we'll 70 spray in tine fall after the leaves
have fallen, il possible,
The aim should he to cover on all sides
all the iwig- and branches Good results
cannot ba expected from spraying merely
one haf or two thirds of the surface OF
the bark. Il Is very good plau in spray
ing for scale to spray with the wind -
That is do not attempt to cover both sides |
OF tie tree the same DAY out only the
winwaTd side, while light brpeze is |
blowing In this way. the wind carries /
the spray though the tree so that the 1
windward side is covered thoroughly |
Then when the wind is in the opposite |
direction, he other SIDE NAV be SPRAYED.
Ordii arilv this method results in much
more thorough work probably requires
less sonlti0n, and Is very much more
pleasant than when one tries to spray
O0th siCes of good SIZED trees the same

Of course, in calm weather, (are in some
localities. especially in sprug, and in
treating small trees these statements alr
lot so applicable.
Spraying for scale should not be neglect.

II Is not always convenient for the
afmer to do summer spraying. Hence
I is necessary that the number of appli-
ations be reduced to those that are most
ssential and yet be sufficient to give
ood results. Fer the apple two applica-
ious will give good results, tbongh three
viii give better. There are usually
dvised for the peach.
For summer spraying the apple a
spray is used, an insecticide
nd funglcide, thus preventing diseases
I the same time, as il poisOns the codling
loth and other bling insects. Bordeaux
fixture was formerly the standard
lngicide for the apple. but lime sulphur $
as 10 a considerable extent supersedt
Commercial line sulphur solution
iluted ] to 40 combined with arsenate
lead in the proportion of , pounds to
} gallons, has given good results IN
Iany localities.
In spraying Winesap the past season, I
le writer used the lime sulphur solution !
I'D secured 80 per cent of perfect fruit, I
ith / per cent wormy and 2 per cent
tier rot; while the apples not sprayed
n 20 per cent, 81 per cent wormy and .
bitter rot Over half the {
lsprayed apples dropped premanturely, !.
bile hardly any of the sprayed apples
opped before picking time. Three
lplications were given. The crop was I
uch larger from the sprayed trees.
It is frequently recommended to give [
rec applications, as follows:
l. Within 10 days after the falling of =
e petals, for codling moth aud diseases;
2. Two weeks later the petals fall;
3. About the first of July, for second =
oOd of codling moth and bitter rot and \
ler diseases.
IN the first application is made thorough Z
the second may be omitted and good ;
Glts obtained, nevertheless. The first =
d third, however, are both important, Q
: third, especially in the south, where
ter rot and other diseases and the late
)od of colding moth are serious factors
e first application is the mostimportant I
2, and special effort should be made to 1
t it on thoroughly and before the
ssoms ends of the apples close, which T
urs usually within ten days after the I
ssoms fall. The reason is that the ma .
ity of the codling moth larvae enter
apple by way of the calyx, or bios.
O end. The aim is to get some of the p
sons solution in each calyx, so that
larvae may be killed before harming
