BLOOMINGTON, 111. - Was
soybean cyst nematode a pi oblem
in your fields this year? Don’t be
too surprised—it may be the most
destructive soybean pest in the
United States.
And now is a good time to con
sider one of the control options
available to stay one step ahead of
SON in coming seasons, says
Charles Brim, manager of soybean
research at Funk Seeds In

“Nematodes are most often
spread to new areas on con
taminated equipment,” Brim says.

criteria for siting hazardous waste
facilities in Pennsylvania will be
discussed at a public meeting in
Room 31'of the Education Building,
333 Market Street, Harrisburg,
between 4 and 7 p.ra. Wednesday,
July 22.
Mary T. Weber, special deputy
secretary of the Pennsylvania
Department of Environmental
Resources and chairman of the
Commonwealth’s Hazardous
Waste Facilities Planning Ad
visory Committee, will preside.
She conducted similar meetings in
Pittsburgh on June 24 and
Norristown on July 9.
The proposed "Preliminary
Environmental, Social and
Economic Criteria and Standards
for Siting Hazardous Waste
Treatment and Disposal
Facihties," prepared by DER with
the cooperation of the 14-member
advisory committee, was
published in the Pennsylvania

ment period ending Thursday, July

“Rotation, resistant soybean
varieties and nematicides will all
help reduce SCN damage,” he
adds.
Resistant vaueties, used in a
well-managed rotation program,
are the most effective, least ex
pensive means of SCN control.
“Although public varieties such as
Forrest, Franklin and Bedford
have race-specific SCN resistance,

comments on the criteria,
prepared under a mandate of the
Solid Waste Management Act of
1980, should be sent to that ad
dress.
The committee has asked that,
where possible, those planning to
speak at the meeting register in
advance with the division.
Speakers are requested to bring
written summaries of their
comments.
The proposed criteria define the
environmental, social and
economic factors which must be
considered to assess the geologic,
hydrologic, sods, air and water
quality, natural, scemc, aesthetic
and economic impact of locating
each hazardous waste facility.
The criteria also define how the
effects of each facility should be
assessed in relation to tran
sportation, population, land use,
ownership and proximity and
possible compensation to the host
municipality.
varieties with both resistance and
yield advantages,” Brim adds.
He suggests growers first
determine it SCN is present in their
fields and the specific SCN race
before planting a resistant variety.
Local crop production specialists
or Extension plant pathologists
can test soil tor the presence of
SCN. "
“Resistant varieties are not
necessarily top . performers if
planted m non-mfested fields. For
example, Franklin will perform
better than Williams under
pressure from SCN, but will not do
as well as Williams if umntested
fields,” say s Brim.
Rotating susceptible soybean
varieties with nonhost crops and
resistant soybean varieties will
also contain the spread of SCN.
Nonhost crops include corn, oats,
small grains, sorghum, and
leguminous forage crops.
“Studies show that each year a
field is free of a host crop,
nematode populations are reduced
by 50 to 90 percent,” Brim points
out. But SCN populations may
increase enough to cause yield
damage m only one year of a
susceptible crop.

However, it Race 4 is a problem,
which it is for many soybean

cautions growers planting Race 4-
resistant Bedford continuously
could increase the chances of a
new race developing, jeopardizing
future resistance.
, Bedford is resistant to only a tew
of the 13 biotypes of Race 4 SCN
that have been identified. Suc
cessive plantings of Bedford could
result in development of
populations of those biotypes
which will attack Race 4-resistant
varieties, further reducing the
effectiveness of planting Bedford
in Race 4-mfested soils.

alternative when resistant soybean

protection in heavy SCN
populations or when rotations
aren’t feasible. Although they
represent the most expensive
treatment method, several ef
fective nematicides and preplant
soil fumigants are available. Brim
says.
But for chemical controls and
resistant varieties to produce full
yield benefits, both must be backed
up with adequate soil fertility, he
adds. Fields should be soil tested
regularly and adequate to high
potash and phosphorus levels
maintained to promote good
growth and reduce nematode
damage.
Finally, growers should pur
chase seed from a reliable source
to prevent field contamination.
"Nematodes may be present on
soil particles attached to seed that
hasn’t been thoroughly cleaned,
and growers- can be introducing
SCN to their fields at planting,”
Brim concludes.
