EXAMINING THE DIFFERENCE between the yield produced
by three hills of Netted Gem potatoes from a plot of
ground infected by early maturing disease which was
treated with Vapam and three other hills which had not
been treated Is Clarence Hill of Henley. The tests were
run for two years and the results indicate a much higher
yield from treated land even under the most severe infes
tations. - -
Results Announced
On Disease Tests
Dr. Hoy A. Young, plant path
ologist at Oregon State College.
reported today on the results of
tests which his department has
been conducting in this area in
regard to the control of a disease
of potatoes called the "early
dying or early maturity' di
sease which is caused by Verticil-
hum.
The fungus which causes the
disease invades the roots and
moves up into the stems, result-,
ing in progressive yellowing, wilt
ing and dying of the plants. Dr.
Young estimated that several
thousand acres of land are af
fected by this fungus in the Klam
ath B.isin area greatly reducing
the annual yield. Loss in yield,
he siid, defends upon how early
the disease becomes severe. Sym
tonis u.tually become apparent
first around the middle of August,
and in severe cases may res'ili
in the total loss of the crop be
cause the tubers will be too
small to mnrket. j
In defining the tests Dr. Young
stated that the Netted Gem potato
is especially susceptible to the
disease and at present no satis
factory resistant netted potato of
good baking quality is available
as a substitute. Crop rotations
with coreals or grasses help to
reduce the severity of flic will
but have not been sufficient to
offset the great losses from the
disease, the report stated.
A new experimental soil fungi
cide, manufactured by the SUtufier
Chemical Company, called Vapam
was tested in 1955 for its effec
tiveness against the early matur
ity disease by Oregon Stale Col
lefv on the Henley ranch of Clar-1
once Hill where the disease has
been established for nearly 27
years and has been becoming an
increasingly bad problem.

by II. J. Jensen and G. K. Page
of OSC. The soil was then I
packed with a cultipacker and j
ten days later potatoes were
planted. A very striking reduction I
in the severity of the disease was)
noted. Dr. Young stated.'
The same area was again ,
planted to potatoes this year to
determine whether or not there
would be any residual effects
from the l.5 treatments. Again,
the report indicates, there was a
marked increase in yield. The
treated areas produced approxi
the untreated sections. This In
dicates that the good effects in
control of the disease may be
carried over from one year to
another. Young believes.
In the 1936 experiments Vapam
was applied at rates of 40 and
165 pounds per acre. The 40
pound .treat "it resulted in yield
increases of approximately 40
sacks per acre while the K5 pound
per acre application resulted in
an increase of over 100 sacks
per acre. The yield from un
treated plots was 245 sacks per
acre while plots given 40 pounds
per acre yielded about 286 sacks
per acre and areas where Vapam
was- applied at the rate of
lb$ pounds per acre produced 344
sacks per acre, the report an
nounced. Hill reports that in addition to
increasing his yield the chemical'
has also greatly reduced the in-!
cidence of weeds in his fields, i

plied either by subsoil injection i

Potato Chip Industry Grows
In Pacific Northwest Area
Oregonians are making potato
chips one of the state's largest
industries. t
Henry Willis of Tacoma, chair
man of the Northwest Potato Chip
Industry said in. Portland yester
day that Oregonians consumed
3,500,000 pounds of potato chips
in 1955, an eating capacity which
has proved a boon to Northwest
farmers as well as to the potato
chip industry.
Announcing the month of Octo
ber, 1956 as Potato Chip Month in
Oregon, Willis said that farmers
sold 43,200,000 pounds of potatoes
for processing into potato chips
last year.
Willis predicts the market for
polaio chips will double by 1957.
The larger market will be due to
a concentrated advertising cam
paign now being planned by the
Northwest Potato Chip Industry to
increase the sale of chips. The
Northwest consumption of chips is
about half of the national average. !
Some 1500 carloads weighing
36,000 pounds each of potatoes ,
from Washington's annual crop
and 1200 carloads from Oregon's
annual potato crop go directly for
local production of po'ato chips.;
The industry -sponsored campaign
would double the present market.
