The Hood River glacier. (Hood River, Or.) 1889-1933, 1916-03-02

This program does not include spray
ing for sphis, leaf roller. red spider.
leaf hopper and other insects and pests.
but Is confined to suggestions only for
San Jose scale, fungus, codling moth,
powdeiy mildew and antbrscnose. which
are the insects and diseases that have
caused the severest losses in Hood Riv-
er valley.
Your attention is especially called to
this fact. that these observations and
results and recommendation have been
made after careful investigation of
fungus control IN SO orchards. They
are classified and show very conclusive
ly that by certain spraying programs
used by number Of growers. that the
best results have been obtained.
Therefore, feel justified in suggest
ing that the grower would be better off
to follow these recommendations than
to take the advice Of some single indi.
vidual grower who has had limited
experience. but inasmuch as you are to
spray your own orchard and must nec-
essarily assume the responsibility OF
the method adopted and depend on
yourself for clean crops, do not feel
justified in urging you to adopt these
suggestions, especially If there is any
doubt in your own mind, or ii these
recommendation are entirely new to
you, and want to say that ! want you
to feel, and even advise you to submit
these programs to the Experient Sta
tion in Hood River, or any of the path
ologists connected with the Experiment
Station at Corvallis. l do not believe
you will find a single suggestion or
recommendation in these programs
which they will consider unwise. al
though 1t may be possible that these
programs may include greater num-
ber of sprays than the Experiment Sta
tion in Hood River or other patholo-
gists may consider necessary, but you
must remember that the scab in Hood
River valley has been exceedigly prev
alent during the last several years. and
you must admit that we have local
condition to meet with which seems
different in reference to fungus than
most other districts. The right kind
of spraying program is absolutely
necessary in order to obtain satisfac-
tory results in the way OF scab control,

how valuable the fungicides used, no
grower can expect to obtain clean
crop unless the different sprays are ap-
piled thoroughly at the right times,
without being too late or too early,
with power at pressure of approxi-
ately 200 pounds, and particularly dur
ing early sprayings the growers cannot
expect to obtain the best possible re.
suit unless every branch, every limb,
every twig and all Of the leaves are
thoroughly and fairly evenly coated
with the fungicides in the early sprays
particularly, inasmuch as it is gener-
ally. considered that the first infesta-
tions are caused from last years leaves
on the ground attacking this years
foliage on the under side. and it is abb
solutely necessary that the spraying
should be up a we'll as down so that the
under side may he coated as we'll as the
upper side.
IL any grower will follow, and do his
work properly. in the suggestions made
in this spraying program. in my mind
there is no doubt but that he can obtain
a crop of apples in Hood River valley
where the percentage of fungus will
not exceed to 10 per cent at the most.
