the larvae of the first, but some of the
second brood, since the poison remains
in position to intercept the larvae when
ever it does enter.
Eggs on Leaves.
A skillful orchardist does not spray
until after pollination has taken place
and the major portion of the petals
have fallen. In the Yakima district in
a favorable season, the rule is to begin
to spray when eight-tenths of the petals
have fallen. After the petals fall there
| is usually five to seven days time in
which to spray before the ealyx closes
so tightly as to prevent the lodgment
Of the poisonous spray. This first
calyx spray should be with high pres
sure, aiming to force the liquid into the
portion of the calyx cup. Since the
eggs Of the eodling moth have not yet
been deposited and may not be de-
posted for some weeks after this spray
ing, the object of this first spray is
to securely lodge this poisonous liquid
in the calyx of each apple on the tree.
Careful observers. like Mr.. Hurst,
note that most of the eggs of the cod
ling moth are deposited on the leaves,
and that the young larvae may feed
little on the leaf before seeking the
apple. This gives an opportunity to
Intercept the larvae by the second
spray, which this time should be
fine mist, coating the under and upper
sides of the leaf.
Moth Cage Is Aid.
To determine the best time for the
second spray is the object Of the moth
cage, the careful observation of which
ascertains when the moth will be ready
TO lay eggs and thus determine the time
for the second spray, which should coat
the leaves just in advance of the laying
of the eggs.
On the other hand the time of the
first spraying is determined by and
must be before the calyx closes. White

tween the earliest and latest closing Of

loss by frost, spray when eight tenths
of the bloom has fallen. If, on the
other hand, the season has been un
favorable, and the early bloom has
been destroyed, and the crop is depend
ent on the later bloom, then do not
spray until the latest bloom has shed its
petals. The orehardist, therefore, will
carefully study his own bloom, and will
spray with reference to that particular
portion of the bloom which in his case
will set fruit. This varies with
varieties
Study of Trees.
To determine when to spray against
the second brood, about the first of
June place burlap bands about the
trunks of the older trees preferably
in some old orchard, or in some orchard
sadly infested with worms. Under these
band traps the larvae Of the first brood
will hide to transform into adults
Place goodly number Of these
worms in the moth cage, study their
development, and spray for the second
brood when the moths are ready to lay
eggs. Tn the Boise basin that would
quite likely be in the neighborhood of
the first Of July. Since the broods over
lap, it might be necessary to spray
again in the early days Of August.
Careful observers believe that in the
Snake River and the Boise Valleys we
have first and second broods only, but
that these broods overlap and may con-
tisue their work even in September.
