There is perhaps no phase of or
eharding that is being perfected and
modernized as rapidly as is the proc
ess of spraying. The change which
naturally comes from climatic varia-
tons, together with the age and
growth of the orchard industry, and
results in appearance Of new troubles
and the increased severity of old
ones, has made the question of spray
ing vital one to apple growers.
Consequent to these conditions to-
gether with the increasing demand
for fruit OF fine appearance, comes
the necessity and the imperative de-
mand for safe and effective treat
ments. Conditions vary in different
localities and even in different or
chards in the same locality, con-
sequently it is difficult to outline a
treatment that is applicable to all
sections and all conditions. There
are effective remedies and preventives
Cor the more important insects and
diseases that directly attack orchard
fruits but their efficiency depends
largely upon the intelligence with
which they are applied. The success
with which spraying operations are
carried on depends more upon the
good Judgment exercised by the
grower in doing the work than upon
the remedies used; that is to say,
work that is poorly done or done too
late, will not accomplish the intended
purpose.
In the eastern states, spraying of
the apple has been more or less ex-
tensively carried on for years There
the development of the process has
been governed almost entirely by re-
quirements necessary to control fun
gous diseases This has resulted in
the adoption and use of apparatus that
will produce fine mistlike sprays which
may be evenly distributed. over the
surface of the fruit and foliage, thus
affording the most complete protection
by the most economical use of mix
lures possible.
In certain western states, however.
where orcharding as an industry is
newer, where through the practice of
intensified methods it has been devel-
oped to a higher state of perfection
than in other sections of the country
and where spraying operations have
been directed chiefly against cooling
moth. the tendency in recent years has
been to adopt appliances that produce
a scoarse spray which may be forced
under high pressure into the calyx
cavities of the young fruits with view
to protect for the entire season that
portion of the fruits against the inva-
sion of worms
In the middle West, where spraying
Is done at all, the tendency has been
to follow the lead of the East. 1t
seems. however. that in this section of
the country, where is is frequently
necessary to protect fruit against both
fungous diseases and insects, the logi-
cal and most practical mode of pro-
cedure to be followed is to adopt
modification or a combination of the
methods in vogue in the East and in
the West by using the western method
for the first spraying for the cooling
moth. reducing the fungicide, where
necessary to use it, to one-half or
even to one-fourth the customary
strength because of the greater amount
of liquid required for a drenching
spraying and adhering to the estab-
lished method for all other sprayings.
