Plant disease clinic aids
PENN STATE A disease clinic
for plants, the only one ot its kinds
m Pennsylvania, operates within
the College of Agriculture at The
Pennsylvania State University.
What’s more, the services are free.
The Plant Disease Clinic at Penn
State can diagnose all sorts of
problems—those caused by fungi,
bacteria, nematodes, viruses, and
air pollutants. Clinic personnel
diagnose problems not handled by
the regular soil and forage testmg
laboratories at University Park.
Managing the clinic is John D.
Peplmski, senior research aide.
The diagnostic staff includes all
Extension specialists within the
Department of Plant Pathology.
Peplmski indicated the analysis ot
plant problems is available to
anyone needing such help.
“Ot all specimens received, 35
percent are referred to us by
county Extension agents,”
Peplmski commented. “The
remaining 65 percent are either
submitted directly by mail, are
brought in personally, or come to
us through faculty and staff
members.”
Many plant specimens are
received from other/states. The
Penn Staters also cooperate with
workers in several other university
clinics of the Northeast to help
understand and solve plant
problems. About 1800 specimens
are processed at University Park
in a year. Of these, some 50 percent

provides valuable information to
aid clinic personnel in diagnosing
plant disease problems.
Clinic facilities include a
laboratory for microscopic
examination of diseased plants.
Lab personnel can also isolate and
grow plant pathogens—disease
organisms. Moreover, virus
analysis is earned out using
certain plants called “indicator
plants” that readily show disease
symptoms. Viruses are also
detected with a technique known
as ELISA, an acronym for the
scientific name of enzyme-linked
immunosorbent assay.
If the plant pathology staff finds
that diseases and air pollutants are
not involved in a problem, then
Extension specialists are con
sulted m other departments—
entomology, agronomy, hor
ticulture and forestry.
“Listings of specimen records
can be produced,” Peplmski said,
