Either rods and MOBILES o. spray
guns may be used in spraying for
,ue cooling moth. Good results
" III lie obtained with either if they
a-'e properly used. Bordeaux or disk
I.ozzles. with an angle, may be used,
the latter being perhaps the most
satisfactory. as they do not catch in
lne trees and need little adjustment.
With most outfits two nozzles may
lie put on one rod by using q. Y.
Spray guns are lighter than rods,
and the spraying can be done some
what more rapidly. but careless work
is more likely to be done than with
the rods. The guns have the advan-
tage of being adjustable. so that a
wide cone Of spray may be used for
close-range work, or a long stream
for greater distances. This adjust
able feature should be utilized the
aim being at all times to Just reach
the fruit to be sprayed. The tops OF
high trees are often only Indifferent
ly sprayed G.'om the ground and
should be reached from the tank or
from q tower.
The disks for guns or nozzles come
with different sized holes, and the
size to be. used will depend on the
amount Of pressure supplied by the
rump. New disks should be substi-
tuted when the holes in the old ones
wear too large.

erial to use in spraying Tor the cod
ling moth. Its chief fault Isl that 1t Is
a rather slow acting poison, and as
the worm burrows into the fruit in
short tins,,. sting Is usually pro-
duced before the worm dies. NO
poison has been found that will kill
the worms so quickly that they are
unable to produce stings. The only
way to decrease the number of stings
ia to reduce tho number of worms to
a minimum.
Either powdered or paste arsen-
ale of lead may be used, the former
being the mo..a convenient For the
codling moth sprays use the powder
ut the rate Of i pound to SO gallons
OF water, or the paste at the rate OF
pounds to SO gallons Larger
amounts are unnecessary and small
err amounts may be ineffective
1ime-sulphur. as used for the pow
derry mildew, may be combined
with areenatn of lead. Dilute the
lime-sulphur in the spray tank first,
and do not add the arsenate of lead
until the tank is full This COM
bined spray should be used al once,
before much chemical reaction has
taken place.
1t appears to be desirable to uae
a spreader with the arsenate of lead
spray. This ovarcomes the formation
OF drops on the fruit, and results In
n more thorough wetting OF the sur
face. Many tests have shown that
the cooling moth may be controlled
lust as thoroughly without a spread
or as with it, but it is somewhat cas-
Ter 10 coat the fruit completely by
using q spreader, thus leaving few
or unprotected areas. The sprcader
does not seem to make the spray
go any farther, nor will 1t cause the
e,ray to spread around to the oppo-
site side of a f.ult. 1t has the adVan-
tage Of eliminating the white blot
ches of spray which interfere with
the proper coloring Of the fruit ana
sometimes make 1t Objectionable to
prospective purchasers.

1t is Of the utmost Importance tina
the various cooling moth sprays
applied at the proper time, since
spray applied at the wrong time ma
be largely wasted. and the fruit ma
be left unprotected when large mum
bers Of worms are Matching; Sine
the time for making the summe
spray applications differs each veal
it is more difficult to ascertain tn
lroper time for applying these spray
than 1t is for any of the other spray
used by the fruit growers OF Wash
fngton.
The calyx spray is applied for tn
rurpose of poisoning the large mum
bers of worms that enter the caly
cup, and is the most important spra
of all. 1t should be applied YER
thoroughly, every calyx cup bein
filed In order to do this. som
growers consider 1t advisable to up
ply two calyx sprays, one right afte
the other. The calyx spray must b
applied between the time the petal
fall and the time the calyx cups close
No time should be wasted, as this in
terval is short, never more than 10 O
IL days.
The cover sprays are applied Il

number necessary will vary with tn
locality and the degree of wormines
OF the orchard. In the majority o
cases four cover sprays should b.
used, two for the first brood and tw'
for the second brood, following spra,
schedule. 4. Every effort should b.
made to eliminate as far as possibl
the first brood OF worms, and tn
spraying for this brood should be un
usually thorough. even though bu
few wornly apples are seen. Th
second brood of worms are all thu
progeny of the first brood. and tn,
