ROCK SPRINGS - Seed
treatment and fungicide spraying
are needed as vital management
tools to combat the increasing
threat of foliar diseases in Penn
sylvania cereal crops, such as the
mildew and Septoria prevalent this
year in wheat.
This was one of the messages
stressed by Penn State agronomy
researchers at a Cereals Field Day
held at the Rock Springs demon
stration plots west of State College
on Wednesday.
Herbert Cole Jr., Penn State
plant pathologist, called on
members of the audience who
represent chemical companies to
get more involved in seed treat
ment.
“Most companies are not really
involved in seed treatment
research,” Cole said.
“Any efforts that result are
usually spin-offs of other research.
• “I’d like to issue a plea that
companies start to get involved in

Lehigh seniors first in judging contest
NEW TRIPOLI - Lehigh
County’s senior 4-H Livestock
judging team kept top honors at
home as they took first place in the
Lehigh County 4-H Livestock
Judging Contest on Tuesday, here
at the Snyder-Lehigh Farm.
The top placing senior team
consisted of Diane Krause, Bonnie
Wessner and Jane Sikorski, who
held the first, second, and fourth
high scores for individuals in the
contest, respectively.
Diane Krause placed first in the
senior division for beef and sheep
judging and in presenting reasons
on the classes. Bonnie Wessner
held third place in placing beef

ments that are systemic.
“We need materials that not only
treat the surfaces of seeds, but also
help to eradicate the disease that
may be beneath the epidermis. We
need research on materials that
can be safely absorbed into the
tissue of the seed to attack these
diseases.”
Cole explained that the so-called
humid mid-Atlantic climate that is
conducive to mildew and Septoria
moved as far west this year as
Indiana and Illinois. He saw large
fields in these states that were
completely defoliated this yeai .>u ■
to mildew and Septoria.
He explained that heavy planting
rates contribute to the creation of a
very humid micro-climate beneath
the canopy of the crop that is ideal
for the development of Septoria.
Also, there is a relationship
between the date of wheat planting
and powdery mildew.
“The planting date and amount

fourth in sheep judging. Jane
Sikorski was the second ranking
individual in judging beef.
'Top individual in the senior
swine judging was Keith Bryan of
Chester County. Keith also placed
fourth in presenting reasons and
was third in judging sheep.
In the Junior competition, Berks
County’s team consisting of Glenn
Heffner, Kenianne Rarick, and
Greg Strieker took first place.
Kenianne placed fifth in sheep
judging and was fourth place in
dividual overall. Teammate Greg
Strieker placed third in beef
of fall growth can help dictate the
severity of mildew that develops in
the spring,” Cole said.
He explained that one plot of
wheat that had been planted on
Sept. 30 just before a shower that
caused germination and the start
of growth has a severe case of
mildew.
And, a plot that was planted a
week Jater and did not germinate
as quickly due to drier weather had
no mildew.
“Wheat production techniques
will become more complicated,”
Cole said.
“They will include planting date,
rate of planting, the rates of fall
fertility and spring nitrogen and
the variety. All will have an in
fluence on the amount of mildew
and Septoria.
“The application of fungicides
will become an important part of
wheat production. We need more

Cole also reported that no
progress has been made on short
rotation of wheat. He pointed to a
plot in its second year of wheat in
which soil-borne disease had cut
substantially into yields.
“A third year of wheat in the
same field in Pennsylvania is a
disaster,” he said.
James Frank, a USDA plant
pathologist, also discussed seed
treatment for wheat. He cited one
three-way combination of a seed
treatment that may hold some
promise for mildew.
In other tests, fungicide spraying
was evaluated and results showed
significant reductions in mildew.
In sprayed plots, mildew amounts
were one-sixth of the disease found
in the unsprayed control plots.

A number of experimental

And there are both early and mid
season variety tests.
Both lodging resistance and
yield are being studied.
State varieties being studied in
