Maple wilt
NEWARK, Del. Maples are
among the most loved shade trees,
but unfortunately, they’re not
problem-free. Maple wilt, also
called Verticillium wilt, is a
common and serious disease. The
destructive, soil-borne Ver
ticillium fungus kills many maples
in Delaware each year. University
of Delaware extension agricultural
agent Bob Hochmuth says he’s
seeing an unusual number of cases
this year due to the stresses caused
by unfavorable growng conditions
over thelast two summers.
Norway maples seem especially
susceptible to infection by Ver
ticillium, but silver, red, sugar and
Japanese maples are also
vulnerable.
The disease organism usually
enters a tree by way of its roots
and spreads through the sapwood
into the upper branches. Even
tually one or more large limbs or
even the entire crown may begin to
die back. Infected limbs produce
sparse, sickly looking leaves which
may wilt suddenly and die.
A diseased tree may die within
one season, or it may linger on,
dying slowly over several years.
Survival time depends on the size
and vigor of the tree, as well as on
general weather conditions.
Egg yield still down
HARRISBURG - April 1984 egg
production in Pennsylvania totaled
331 million, 14 percent below April
1983 production, according to the
Pennsylvania drop and Livestock
Reporting Service.
The average number of layers on
hand during April 1984 was 15.8
million compared with 17.8 million
on hand a year ago. Egg produc
tion per 100 layers was 2,098

is common
Olive-green streaks sometimes
appear in the sapwood of wilt
infected maples, usually in the
trunk and larger limbs. For a
definite diagnosis, take part of an
infected limb to a county extension
office.
Hochmuth says the disease is
hard to control after it becomes
established, so he recommends
cutting down and destroying
seriously infected trees. However,
a tree that’s in fairly good health,
with only a few limbs infected,
may be worth trying to save.
Rescue efforts involve removing
dead and dying branches, watering
during dry spells, and fertilizing
generously. If the tree was not
fertilized in early spring, apply a
10-6-4, 10-10-10, or other high
nitrogen fertilizer as soon as
possible.
As with many plant diseases, it’s
better to prevent maple wilt than
to attempt a cure, Hochmuth says.
So keep maples (and other trees)
in healthy, vigorous condition by
fertilizing properly (every other
year for maples), watering,
pruning, and repairing injuries. A
tree that receives proper care is
less likely to become diseased and
should thrive for many years.
compared with 2,207 for April 1983.
The nation’s laying flocks
produced 5.64 billion eggs during
April, fractionally above the 5.62
billion produced a year ago. The
total numer of layers during April
averaged 278 million, one percent
above the 275 million a year ago.
April egg production per 100 layers
was 2,030 compared with 2.045 eggs
for April 1983.

High tech food processing

by seasonal availability. Food
processors want a steady,
dependable flow of raw products
often year-round. This is seldom
possible in the mid-Atlantic, so
buyers prefer to deal with southern
or western suppliers.”
Nationally the trend is to locate
new food plants closer to raw
commodity sources. By
cooperating more closely, can food
processors, university research
and extension personnel, and
farmers in the mid-Atlantic
reverse this trend and stimulate
more regional production?
Primary food processors--
canners, driers, freezers, bottlers
and packers-deal directly with
farmers. Secondary processors
(those who take food ingredients
and further process them into such
things as TV-dinners, chicken
franks and health foods) are more
isolated from farmers, but Vaughn
says their decisons strongly in
fluence demand, cropping patterns
and farmer profits. HTFP would
be concentrated among the
secondary processors.

Vaughn says high tech food
processing and farm interests need
to work together to assure
processors the best possible supply
of local raw commodities while
strengthening regional agricul
ture. Many Delmarva farmers
are willing to consider growing
other crops for which there’s a
good market.
“Those who favor developing a
regional HTFP industry should
also consider the possibilities for
expanded international trade in
processed food products,” the
economist says. “Commodities
like sugar, tea, coffee, and cocoa
shipped into eastern ports offer
opportunities for mid-Atlantic
processors. Going the other way,
increased exports to affluent
foreign buyers might open up
markets for high quality foods

processed in this region.”
He says decisionmakers must
also take into account the en
vironmental concerns involved in
food processing. Questions about
water availability, waste disposal
and rising energy costs cannot be
ignored. '
“Since governments, businesses
and private individuals all in
fluence a region’s economic
development,” Vaughn concludes,
“high technology food processing
may warrant combined public and
private investment. But before
that can happen, the benefits and
costs involved as well as the
available resources-both raw
materials and support services for
research and development-should
be fully evaluated. Only sound
investment decisions can improve
the region’s economy.”
