The Agricultural College at Pullman
has issued bulletin describing the
manner Of spraying for the codling
moth and the value to the fruit grow
er, to be derived by proper care of
the orchard. The bulletin contains
much valuable information and will be
sent free to anyone on application to
the college. The following extracts
are reproduced:
1t is asserted that 1900 carloads Of
apples, valued at 100000, were carried
by rail last year from the inland en-
pire. This was less than One-half Of
the total amount grown, yet the re-
mainder was not shipped. Why? Be-
cause it was wormy. and was left to rot
or to be consumed at home. If these APP
pies had not been wormy, those that
were left to rot would have been sold
and the income Of the people would
have had an increase of $4,000. The
rest would have had better taste
at home. and the cider mill could have
produced a cleaner beverage. 100000
is a big tax to pay to a worm can
the farmer afford it? Many fruit
growers are unwilling to believe that
the cooling moth is the cause of their
wormy apples. Their apples are
wormy but are made worthless by a
borer or maggot, they assert, but no
Cooling moth car be found in their
orchard. In nearly all cases they are
mistaken, and the blame for the dam
age almost always falls to the Cod
| ling mOth-not the moth itself. but the
larva, or worm form of the insect.
The object of spraying is to coat
the food Of the newly Matched worm
with poison. SO that its first meal will
be its last also. Inasmuch as the worms
of the first brood attack the apple gen.
orally at the calyx end it is the aim
of the first spraying to place the poi
son there. This best effected after
the blossoms have fallen but before the
calyx cup has closed. But as the bios.
SONS of the apple fall about two weeks
| before the majority of the worms enter
the apple, it is necessary to spray q
second time two weeks after the frs
treatment
Paris green Is almost universally
used against the Cooling worm. This
Is mixed with lime to prevent scald
ing the foliage. The formula for ap.
pie and pear trees stands:
Paris green one pound; lime one t.
two pounds; water $50 gallons. II
an arid climate but little lime is nee
essary. Many fruit growers use NJ
lime. Too much lime hinders the ac
ton of the Paris green. The mixture
should be we'll agitated while spraying
to keep the liquid uniform. Arsenic
lime and soda is equally effective ant
costs one third as much. Its formul;
is:
White arsenic one quarter pound
washing soda one pound water on
quart Dissolve by boilinf Add t
100 gallons of water and eight pound
Of freshly slaked lime. This clusters o
apples to one fruit while the majorit,
Of the first brood are still within tn
apple. (about the middle Of June) ant
bury the infested fruit. II the worm
apples are not thinned they will dro
off anyway after the worms ar
through with them. The more Of tn
first generation destroyed the less o
the second there will be to make tn
apples wormy. Keep the orchard clear
Rubbish assists the Cooling moth il
it's transformations. The more tn
worms in the ground are disturbed b
cultivation the less chance they hav
of surviving. Scrape loose bark fror
; the trees to deprive the worms of
safe cocooning place. Birds arI chick
ems, ants and other insects. hogs, mois
ture, cold. hot sunshine. and sicknes
kill many worms.
Especially should birds be protecte
as the benefit derived from them
great.
