WASHINGTON, D.C. - A
$242,500 U.S. Department of
Agriculture grant may help
scientists solve a genetic
riddle to cut down on
Widespread damages cyst
nematodes do to soybeans.
Anson R. Bertrand,
director of science and
education for the USDA, said
the special cooperative
grant will support the on
going anti-nematode
research at the University of
Missouri agriculture ex
periment station for three
years, '
An answer to the genetic
riddle may come from
breeding multiple
resistances into soybean
varieties, said C. H. Bald
win, Jr., soybean pathologist
and principal investigator
for the project. That way, he
said, the soybean plant
might be able to ward off the
nematode as it switches
from one genetic “race” to
another.
Nematodes are classified
under four “races.” Baldwin
and other researchers
believe there may be a need
to add more “races” as was
indicated in studies by
Robert D. Briggs, University
of Arkansas nematologist,
and colleagues in the plant
disease sciences.

sponsors research to cut soybean cyst damage
A larger number of
“races,” said Baldwin,
would widen the number of
possibilities for isolating and
then crossbreeding
nematode-resistant genes
into soybean varieties.
As things stand, farmers
face a dilemma in planting
soybeans that are supposed
to be resistant to the cyst
nematode. What happens is
that the nematode reacts to
the genetically-bred
resistance and a different
“race” simply ac
commodates itself to the
crop, making it susceptible
to damage.
University researchers
will plant special soybean
germplasm to build up cyst
nematode populations.
Studies of these will follow
basic work already un
derway and partly funded by
the USDA.
Scientists will grow
soybean plants susceptible
to the cyst nematode in field
plots at the experiment
station farms or at the Delta
Research Center in Por
tageville, Mo. Out of these
plants, plus those of
resistant varieties, they
hope to find clues to
developing strains that
resist various populations of

Baldwin.
At the same time, other
scientists will analyze plant
tissue m soybean varieties to
identify the biochemical
pathways by which the
nematode attacks the plants.
These and other findings are

In part of the detective
work on cyst nematodes,
low-level aerial photography
is used to locate areas of

southeastern Missouri, near
the Delta Research Center.
Soil samples now will be

soil characteristics, fertility
and drainage patterns affect

said, all oak and chestnut
lumber from the United
States will have to be ac
companied by a federal
phytosanitary certificate
declaring that it is free of
bark.
In addition, it must be
squared edged so that no
natural rounded surface
tissues remain, or have a
moisture content of less than
28 percent.
If one or the other of these
two conditions is not met, it
must undergo one of the
following treatments: Hot
air or hot-water treatment at
109 degrees Fahrenheit for
48 hours; hot-air treatment
at 129 degrees F. for 24
hours; or hot water treat
ment at 109 degrees F. for 12
hours. Special provisions are
made for oak veneer logs
with bark, since removal of
the bark tends to damage the
logs for veneer production
purposes.
Beginning June 1, these
logs may be imported into
the Netherlands, Belgium,
Luxembourg, Italy and West
Germany; provided APHIS
or state plant regulatory
officials certify that the logs
originated in a country free
of oak wilt—including
allowance for a 6.2 mile
buffer zone around any in
fected counties.
Oak veneer logs harvested
before June 1 will have until
October 1 to reach their final
destination under present
export regulations.

Oak wilt is caused by a
fungus which invades vital
fluid-conducting tissues in
the tree, stunting growth,
weaking the tree and
eventually causing its death.
