THORONEss IN CALYx SPRAY
At the six demonstration meet
ings on various phases OF the ap-
plication of calyx spray conducted
by M. D. Armstrong. extension
specialist in horticulture, the fact
was brought out that a more thoro
job of spraying needs to be done.
At every meeting growers were
given opportunity to spray trees
i'm the orchard while the crowd
watched the job. After the grower
had SPRAYED the tree his work was
criticised by those watching and
the tree was carefully examined
| for dry spots. In nearly every IN
stance it was possible to find twigs
two or three feet long that had
not been covered by the spray and
sometimes even the county agent
and the specialist failed to hit all
of these branches with enough
spray to give them what many
growers would consider a thoro
application.
Before starting the spray DEM
onstration various growers were
asked their opinion as to the a
mount of spray required to cover
a certain tree and usually there
was quite wide variation and al
ways few growers who felt that
half to one-third of the amount ac-
tually required would be sufficient.
The main thing which Mr.. Arm
strong emphasized in the spray
work was thoroness in the appll-
cation of the calyx spray. This IS
of more Importance this year than
ever before. because of the spray
residue problem. Anything that
can be done to control the first
worms Matched or those of the en-
tire first brood will do much to
lesson the need of application OF
large amounts of lead later on.
Growers were found who had been
able to do away with the second
brood spray by thoro application
for the first brood during last
season. Mr.. Armstrong advises
very strongly the use of the codl-
ing moth traps at least a dozen to
each orchard to determine the
prevalence of moths in the orchard
and just their time of appearance
and as a check later to determine
whether the second brood spray
may be necessary. These traps
should be of granite ware or If
tin coated use parafine or an as
phalt paint so as to protect them
from the material used in the trap.
Traps should be at least five or
six inches deep and may be sup
ported in near the top of the tree
with a pole set up thru the center,
or from branch near the top of
the tree. When moths are flying
in abundance traps must be clean
ed out daily, but when few num-
bers are flying it may be possible
to visit them only once In three or
four days. 1t must be remembered,
however. that the surface must be
free enough of moths that other
moths can get to the liquid easy.
Brer Rabbit molasses which can
be secured in small lots at local
stores. is found to make good bait.
This can be diluted 1:20 and the
yeast added as with other bats.
Apple cider or Diamalt, the latter
manufactured by the Fleishman
Yeast Co. and secured in ten gal
lon lots at $3.50, are both good.
The size of the opening in the
gun is another matter of import
ance. With small openings one cam
not reach the tops of many of the
trees and Mr.. Armstrong recon-
mended nothing smaller than 1854
of an inch. The size of opening
will be guaged by the pressure
which one can maintain and this
should not be less than $50 to .450
pounds for best results. Many of
the old outfits cannot maintain this
pressure and then the number of

where you can maintain pressure
enough to reach the tops in good
shape. 1t is possible to do good
spraying with low pressure outfits
but you must be very particular
with the work in order to do so.
Do not be in a hurry to put on
calyx spray. Of course, you must
gauge the time of starting by the
amount of work to be done and the
size of the outfit and it is easier
to do thoro job after at leas.
go percent of the petals have fall

Application may be applied until
the calyx lobes are pointing pretty
well upward.
We believe it would be well for
each man spraying to turn one
gun over to the helper and then get
back Is or 100 feet if possible,
and watch him do the spraying,
and then take the gun himself and
have the helper do the same for
him. We believe that nearly every
one will find that the other party
can give them points on where they
are missing parts of the tree. Mr..
Armstrong recommended that the
