Information on Spraying For the
Codline Moth of Value to
Fruit Growers.

At CnlS season OF tne year IL becomes
the duty of the fruit grower for his
own protection to guard against the
ravages of insect pests that are so in
furious to fruit. It is q time when
that dreaded and busy little insect, the
codling moth, requires extinction, and
about the surest way Of eliminating
the pest is by spraying. Washington
fruit has won its reputation to q large
extent because Of its perfect condition,
which cannot continue If insects COM
mon to older fruit growing districts
secure possession Of the orchards of this
county. We publish the following in
formation and instructions At this time
as it is issued by the State Commission
er of Horticulture and written by A. L.
Melander, who has thorough knowl-
edge Of the subject treated:
"The codling moth is a brownish
miller about one-half inch in length,
which lays eggs on or near apples. In
little over q week the eggs hatch into
codling worms. In nearly all localities
two distinct broods of worms occur each
year. After feeding within the apple
for several weeks the worms leave the
fruit to cocoon. Most worms make
their cocoons in the ground, many can
be found beneath the rough bark The
cocoon stage is completed in from two
weeks to = month during the summer
Worms leaving apples late In the SUM-
mer remain in the cocoons over winter.
When the cocoon stage is completed
the codling worm has changed to the
codling moth, and is ready to lay its
eggs. -
The only remedy for the codling moth
is spraying. Other measures are use-
full but can not be depended on alone.
Clean culture, especially stirring up
the ground beneath the trees, is of
great Importance as it destroys the
worms In their cocoons. Banding trees
with burlap will trap 40 per cent. of
the worms. Apples should be thinned
so that no two touch. Trees should be
pruned SO that they can be easily
sprayed and cultivated. A new or
chard should be set with trees 30 feet
apart to allow for passage for the spray
ing outfit in the future.
After the codling moth has entered
the apple spraying does no good. The

ing of poison through which the worm
enter where apples touch. II the fruit
is thinned so that no two apples touch
the worm is more likely to get poisoned.
Most of the early worms enter apples
at the blossom end. In order to place
poison in the blossom end . spraying
must be given just after the petals fall
and before the calyx cup closes. This
will be several weeks before the first
worms are Matching, but must be given
1t is the most important spraying of
all. The other spraying should be CIV
en- just as the first worms of each brood
are Matching.
The time for the first spraying is
definitely fixed. But there Is more
doubt as to when the other sprayings
should be given. The best time for
spraying can be easily ascertSined by
the following simple method. In
quart glass jar place a number of CO.
coons obtained from the trunk of an in
tested tree. This jar should have
cloth cover, and should be placed in
the shade in the orchard. Add ten
days to the date when the moths first
appeared in the jar, to allow for the
Matching of the egg and the date for
the second spraying is obtained. OBJ
tain some new cOcOons q month or 80
later and rear the moths of the second
brood in the same way. The date for
the third spraying is thus found. A
fourth spraying should be given one
month after the third In the warmer
localities.
Lead arsenate is giving better salts
faction than any other substance. Lead
arsenate can be obtained on the mar
ket most economically as Swift's arsen-
ate of lead, or as disparene. Mix two
pounds of lead arsenate paste with so
gallon of water. Give three or four
sprayings, which are necessary. One
spraying alone will do no good"
