Will smut destroy China connection?
Will a disease called TCK
smut destroy Pacific Nortl.
I west wheat growers' multimillion-dollar
China connect
ion? Yu Shan-Qian (pronounced
"ooh san chien") did not offer
many clues during a recent
interview conducted through
an interpreter at Oregon State
University.
Just the same, the soft-spo
ken, friendly Yu, a planl
pathologist from Fudan Uni
versity in Shanghai, may dc
the first to know.
He is the first representat
ive of mainland China's scien
tific community to come to the
Northwest for an extended
study of TCK smut, a fungus
disease that historically has
caused trade problems with
China and this winter sparked
a renewed Chinese ban on
importing wheat from the
Northwest.
The 44-year -old scientist
was invited by U.S. Wheat
Associates, a marketing or
ganization whose Asian office
is in Portland, to conduct two
y ears of cooperative research
all expenses paid-in the OSU
laboratory of Edward Trione,
a U.S. Department of Agricul
ture botanist who is a TCK
smut expert.
The hope of U.S. wheat, and
Northwest growers, is that
such joint research will help
the Chinese adopt the view
that TCK smut, which cuts
wheat yields by turning the
grain to a worthless black
powder, is severely limited by
terrain and weather condit
ions and poses no threat to
China, said Trione after Yu's
June arrival in Corvallis.
From his country's point of
view, Yu later explained in the
interview, China's scientists
"have no way to judge" the
danger of the disease, which, is
in virtually all wheat shipped
from the Northwest in the
form of microscopic spores.
Yu is the vanguard of an
effort to educate Chinese
scientists.
"We are starting our own
research program at Fudan to
study the possibility of TCK
problems starting in parts of
our country similar to here,"
he said. "We need this
research background to know
if what we are told is true or
""t."
Another incentive for study
ing TCK smut, said Yu, is that
China is beginning to detect
the disease in the millions of
tons of wheat imported from
areas other than the Pacific
Northwest.
Specifically, Yu's reason for
coming to Oregon is to learn
how TCK smut developes-to
verify under what conditions it
germinates, he said.
After he completes an
intensive, seven-days-a-week
language course intended to
overcome the communicat
ion? barrier, and takes an
intrHuctory tour of the
Northwest, Yu looks forward
to setting aside the inevitable
inquiries about his govern
ment's position on wheat
imports and moving into the
laboratory.
"I am a scientist," he said,
admitting through a polite
grin his discomfort with such
inquiries. "I cannot say what
my government will or will not
do."
He explained that his visit to
OSU was coordinated by the
chairman of his university
department, who headed a
Chinese delegation that visit-
' Northwest wheat growers
and scientists last year, and
not the Chinese government.:-
Still, he added, the head of
the Chinese Ministry of Agr
culture's plant quarantine
bureau met with him and his
department chairman befon
he left home and spok
encouragingly of his research
His very presence in th
Northwest may be cause for
optimism among wheat grow
ers, he pointed out.
"I believe such cooperative
research with Dr. Trione will
not only enhance science but
further the agriculture trade
between our two countries,"
he said.
Trione agrees.
The USDA botanist said
"the science is on our side" in
the debate over TCK smut.
Us holiovac fho Hnv ami it
spores enter China regularly
from several sources-including
contaminated cargo ships
from Japan-without causing
problems.
"The best way to counter
their fear, though" he said, "is
to keep talking to them and
encourage coiiaoorauve re
search. "It is not my intention to try
and convince Mr. Yu Shan
Qian of anything. I want to
give him the opportunity to
learn for himself about the
disease-in the laboratory and
in the field.
In Oregon the disease is
limited to a relatively small
area in the northeastern part
of the state, said Trione.
Mixing of wheat for export
at Columbia River ports
contaminates grain from the
Willamette Valley and else
where. After Yu completes his
language course in mid-Aug-gust,
Trione said he will
encourage him to spend a
month or so touring western
states including Oregon,
Washington, Idaho, Montana
and Utah and talking with
scientists, growers ami others
In the wheat industry to'
broaden his knowledge of TCK
smut.
The USDA researcher,
whose own research Includes
trying to improve methods of
detecting the disease and
trying to find a way to control
It, said It appears a second
Chinese scientist, a specialist
from the country ' plant
quarantine bureau, will travel
to OSU this fall to do TCK
smut research under the
sponsorship of U.S. Wheat
Associates.
