sation with him I asked his opinion

| OF the one spray theory.
HE said that under certain condi-
tons good results can be obtained
with the one spray method, but that
he had never considered it safe to
recomemnd for general use.
so then l would lay a good deal
! of the responsibility of the wormy
apple situation to the one spraying
idea and the improper application of
that one spraying
Among other conditions which
have tended to increase the wormy
apple situation are: The irregular
blOssOming period and thus the i'm
possibility of filling all the calices at
the same tine. Then there were a
large number of new growers in the
valley this spring, many of whom
knew little or nothing of the orchard
business.
Il am inclined to believe thai the
trouble was with the poison. How
ever, it would be well enough to in
sist on the different dealers having
the different brands analysed before
another season.
SO far / have expressed my ideas
as to wherein we fell short this year.
Now the question is, how shall we
spray next year?
Il have expressed a disapproval of
the one spraying idea, but l would
say right here that | believe thor
oughly in Professor Melander's the
DRY. That is, go after the first brood
hard and get all of them if possible
and then there will be no second
brood. And I also agree that the
first spraying is far the most effective
if properly applied. But We have
seen that it can not be depended
upon to give satisfactory results
alone
The time of the first spraying is
not determined by the condition of
the insect, but is determined entirely
by the condition of the blossom, or
more accurately speaking, by the
condition of the calyx. At the time
the petals are falling the calyx is
wide open, and by the use of high
pressure $50 to 200 pounds and a
Bordeaux nozzle, which throws
course spray, the liquid spray can be
forced down between the stamens
and deposited in the calyx cup.
"A few days later this calyx closes.
If it were not for the closing of this
calyX it would not be necessary to
spray for about a month later for
the first time. For there are no
moths Matching until the later part
of May or the first of June, accord
ing to the weather. Then the only
object in the first spraying is to get
the poison in the calyx cup while you
have the opportunity.
But between the time of the first
spray and the Matching of the first
moths the apple expands to the size
of the end of your finger or larger
and large surface is left unprotect-
ed. While the majority of the first
brood enter the calyx. they do not
all enter there
Therefore, / consider is necessary
to apply another spraying Just before
the little worms of the first brood en-
ter the apple. This is about the first
Of June here. but the time can be
determined more accurately by the
use of the breeding cage.
This second spray should not be
applied just as the first. For the
second spray the vermorel nozzle
should be used and such high pres
sure is not necessary. The idea in
the second spray is to make a fine
mist and thoroughly cover the sur.
face of the apples.
IF, after these two sprayings there !
IS any showing at all of the first
brood. that is if any wormv ann}es
are found between the first of Juno
and the twenty-fifth of July. then I
would apply third spraying about
the time the second brood of worm;
start to hatch, which can be deter
mined by the breeding cage A fourth
spraying should not be necessary. :
The keynote of spraying is thor
oushness and accuracy. Poor spray
ing is money thrown away.
L can not go further into detail
IN this paper, but hope that those
who are uniformed or are in doubt
next spring will feel free to call on
the inspection service for anv assist
ance along this line that we NAV be
able to give
This year We have learned valu
able lesson by costly experience. Next
year We will profit by our experience.
| predict that there will be more good
and effective spraying done than ever
before. And the prospects now are
Tor the biggest, the best and the
PrOD OF fruit that VIC have !
