Controlled
Solution to Quality
Controlled atmosphere stor
age may be the most logical
solution to the problem of
maintaining the quality of
D'Anjou pears in storage and
to meet any late season for
eign competition, according to
Professor Henry Hartman,
horticulturist with Oregon
State college. .
As it is now, the professor
told the audience at the an
nual pear. meeting here, the
quality of the pears after
March 15 In storage cannot
be guaranteed.
Competition comes from a
number of foreign sources.
One of those presenting the
most serious threat is Argen
tina. Since their seasons are
the reverse of ours their fresh
pears hit the peak of the qual
ity in late March and April
The main problem in Argen
tina has been lack of cold
storage. However, the county
now has a half a million box
capacity and cold storage fa
cilities are now under con
struction to provide a total
capacity of 1,188,000 boxes,
the professor said.
Consider Angles
"We cannot rush into this
- controlled atmosphere stor
age pell mell," Professor
Hartman said. "A number of
angles must be considered
A common practice in this
type of storage is to line the
packing house room with
sheet metal to provide an air
tight storage, .Hartman ex
plained. However, this costly
method may be replaced with
a plastic material.
"We don't have all the
angles or the exact procedure
worked out. It takes about
five yeas to be sure of recom
mendations for the carbon
dioxide content for this type
of storage," he added. "We
still don't know what the fi
nal recommendations will be
even though we have been
working on this type of thing
a little over three years."
Net Sit Idle
"Meanwhile, I do think we
have to go into this form of
storage in self-defense," the
professor commented. "While
we are waiting for the final
recommenda tions to be
worked out we should not sit
idle. We should push all ex
periments along this line. A
pilot plant also is needed so
the costs can be figured out
for the adoption of this type
of storage on a commercial
basis."
The professor indicated the
present experiment being con
ducted at Root Brothers pack

be constructed so they can be
converted to atmospheric
storage."
The professor pointed out
that the pear industry should
not expect to see the same
striking results from the new
type of storage as experienced
in the eastern apple industry.
There the marketability of
the Macintosh apple was
greatly increased by prolong
ing the shelf life of the fruit
and maintaining a high level
of quality late in the season.
Drainage Problem
Marvin Shearer, irrigation
specialist, Oregon State col
lege, told the audience of
growers and shippers, "Most
of you have a long ways to
go in applying water effici
ently. The drainage problem
you now have is very small
compared with what you are
going to have."
Shearer said something can
be done about it. Proper irri
gation also depends on how
a neighbor uses water. Na
turally, Shearer said, a
grower must first become
aware of what the problem
means to him financially be
fore he starts to do something
about it.
Shearer related how dry
and wet plot experiments
were set up and the results
from each. The wet plot re
sulted in 26 per cent increase
in the dry matter and 43 per
cent increase in the amount
of water in the fruit, he said
Reports Good Control
L. G. Gentner, entomologist
at the Southern Oregon
branch experiment station,
reported good control of San
Jose scale in the dormant
period with a combination of
either lime sulphur and oil
or Poly Sulphide compund
and oil emulsion. Parathion
applied at the rate of one
pound per 100 gallons of wa
ter also give good control of
scale in the pink stage or
later.
San Jose scale consists of a
tiny circular blackish to gray
ish scale found on the wood,
the entomologist explained.
Underneath the insect remains
stationary and continues to
suck the sap from the branch
es to devitalize the tree and
kill some of the smaller
branches. This means a loss of
fruit. The young may settle
on the., fruit and cause red
spots which also may cause It
to be culled.
The young appear about the
LOT
Problem
first part of June. Lately In
this area another brood has
appeared about the last of
September up to the middle of
October.
Disease Abundant
This tree disease has been
abundant recently because the
natural enemies have apparnt
ly disappeared. This is main
lythe parasytic wasp which
lays eggs in the scale.
A delayed dormant applica
tion of a combination of lime
sulphur or Poly Sulphide
compound and oil has given
good control of the psylla
adults and killed most of the
numphs as they were crawl
ing, Gentner stated.
He also pointed out that
the wet plot in 1932 showed
a 30 per cent increase in vol
ume of it and 1936 showed
a 32 per cent Increase in fruit
volume. Of course, these ex
perimental results depended
on the type of weather hot
or cold and good root de
velopment. Shearer suggested growers
smooth their orchards so wa
ter will not stand in pockets.
Use of cross ditches is valu
able to proper drainage, he
said. There is no such thing
as partially wetting the soil,
he added.
Pear Blight
C. B. Cory, county horti
cultural agent, discussed pear
blight and its control.
The blight has become a
problem in this area during
the last two years, he com
mented. During the winter it
lives in cankers. Oozing of the
sap or sugar from the cankers
in the spring draws ants, beet
les and flies who spread it
through the tree.
Bees spread it from blos
som, to blossom. However, af
ter. they go back to their hive
they will not bring it back
out again.
First thing to do is to cut
the hold-over cankers before
the trees go Into bloom, the
horticulturist advised.
A hundred per cent of the
continued infection results
from short cuts, Cordy said.
Bacteria in about 50 per cent
of the small cankers winter
over.
A solution of streptomycene
and copper should be applied
to the trees in spray form
when 30 per cent of the blos
soms are open, he said. Spray
should be applied again when
the blossoms are in full
bloom. Also, trees should be
sprayed again if there are any
late clutches of blossoms.

Assessors Have Meeting
On Commission Rules
Salem (ffl An advisory
committee of county assessors
met with the State Tax com
mission valuation division
here Friday to talk over com
mission regulations.
Chief Valuation Engineer
Harry Loggan said the asses
sors had 'some complaints
about the commission's log
valuation regulations, especi
ally in eastern Oregon.
Some eastern Oregon asses
sors feel that log values
should be lowered about $5
from last year due to the de
cline in the lumber market.
The commission has ordered
the log values kept up.
Loggan said there might be
some appeals from the log
regulations which were mail
ed out last week.
The advisory committee
suggested that the state's
three tax commissioners
should meet with county as
sessors at least once a year
to iron out differences of
opinion.
Loggan said some minor
changes in log regulations
suggested by the . advisory
committee would be studied.
Present for the meeting
were John Gault, Harney

dent of the County Assessor's

Equipment for the new den

house has arrived and will be
installed in a room which was
vacated last week, Dr. Silly
Blackstone, Kiwanis club den

nounced. The clinic will open about
March 1 and will operate on a
permanent basis during the
school for needy youngsters.
School nurses will determine
youngsters eligible.
Income from the Kiwanis
Kapers on Feb. 26, 27 and 28
and March 1 will be used to
finance the countywide clinic.
Dentists in the county will
serve without fee for the
project.
