CONTINUE THE SPRAYING.
Frequent Showers Make Additional
Spraying Necessary.

Owing to the many transforms during
the latter part of the month of May,
much of the effect of spraying has been
lost, and, consequently. the work
should be repeated at once. in order
to catch the first crop of codling moth.
The theory that the first brood of moth
matches only in the calyx of the apple
is now pretty thoroughly exploded.
Actual experience during the past five
years in Utah demonstrates very con-
clusively that there is well-nigh con-
tinuous Matching of codling moths
throughout the season after the
weather becomes warm at night-say
about So degrees. The cold rains that
washed off the SPRAY have also served
to retard the Matching of the worms,
thus giving the orchardiSt an even
chance with the insect enemy. The at
tention of fruitgrowerS is especially
called to these facts at present, to the
end that such work may be done as
TO accomplish results regardless of the
old-time theories and the very unfa-
vorable weather of the past month. a
thorough spraying of all apple, pear
and cherry trees about June 10 is de-
cidedly necessary, not only to combat
the codling moth, but especially to
catch the pear slug, which did such
disastrous work on pear and cherry
trees last year. Many orchards last
year that were almost defoiiated by the
pear slug are this year barren of fruit,
and the failure is attributed to the Sc
we're cold. while, in fact, the weakened
condition of the fruit buds because of
the ravages of the slugs last year rem
dered the tree unusually sensitive to
the cold, and thus the crop was easily
destroyed. Although the people were
warned last year OF the approach of the
pear slug, many claimed that the warn
ing came too late, and that there was
not time to prepare to fight the slugs.
There can be no such complaint this
year. Owing to the late season it is
not likely that the slugs will make
their appearance before June %, and in
some parts of the state even much later
than that. A thorough spraying with
Paris green and lime, as recommended
for the codling moth, will most effect
ually apnihilate the young slugs. Var
ious substitutes for spraying have from
time TO time been suggested in fighting
the slugs. Experience proves that,
while many of the slugs may be killed
by busting with lime, ashes, road dust,
etc, still there are many chances for
the insects to escape the dust, and,
upon the whole, these processes are less
certain than the spraying.
Without going into detail regarding
the habits of the army of insects that
Will invade the orchards during the
recommend that the spraying with
Paris green be repeated every fifteen
days throughout June, July and Au-
gust. The light fruit crop and the con-
sequent high prices that will most
likely obtain justifies extraordinary
measures TO produce the best possible
quality of fruit. Because of the light
loads on the trees, the fruit will I'M
doubtedly be of fine size, and if, in adj
dition, the ravages of the worms be
prevented, the prices obtained will go
far toward making UP for the shortage
in quantity. Never has there been
greater inducement for Utah orchard
lists to properly care for their fruit. and
with the light of experience to guide
them. there should be no hesitancy re-
garding the matter of spraying to COM
bat the insect foes. J. A. WRIGHT.
