ning noxious weeds through the

Pesticides Herbicides and
insecticides work well when ap
plied correctly and in the proper
concentration. However, there are
times when performance is not up
to expectations. Again, use your
rating system to evaluate each
product used. Rate control as: 1-
excellent; 2-good; 3-fair and 4-
poor. Let the numbers aid you in
selecting herbicides based on
performace. Other factors that
might have a bearing on per
formance are soil type, rainfall
and drought.
Insecticides are important in
controlling soil insects, especially
in com after com rotations.
Rootworm build-up should be
monitored and kept under control
for two reasons. One, rootworm
larvae feed on the roots of com
plants and contribute to root

lodging. Two, rootworm beetles
will feed on com silks and, if
concentration is dense before
pollination is complete, they can
impact seed set. Changing in
secticides from time to time should
be considered, since scientists are
reporting rootworm resistance
where the same product is used
continuously for control.
Drainage Poorly drained
areas should be mapped and
corrections made depending on the
size of the general area. Sitting
high atop a combine gives a fresh
vantage point to the size of the
affected area and the effect of
those areas on yields.
Harvest is an excellent time to
evaluate performance of all inputs
used in a cropping enterprise. An
unbiased systematic evaluation
must be recorded, so that when the
harvest season is completed the
dust settles, you can objectively
evaluate harvest performance.

NEWARK, Del. - University of
Delaware extension horticulturist
Charles W. Dunham retired Sept. 1
after 30 years of service as a
teacher and researcher. For the
last 10 of those years he also served
as extension horticulturist.
Dunham, who joined the
university in 1954, was largely
responsible for developing the
College of Agriculture Sciences’
undergraduate program in or
namental horticulture a major
attraction for students majoring in
plant science.
A specialist in plant nutrition,
during his early years at the
university Dunham conducted
considerable research on
greenhouse crops of the type then
grown in commercial nurseries in
Delaware. He also studied holly
nutrition and culture with the
partial assistance of grants from
the Holly Society of America as
well as federal Mclntyre-Stenms
forestry funds. Later, he studied

tomologists from the University of
Delaware will be conducting a
European com borer (ECB) fall
abundance survey throughout the
month of September as part of
their plant pest survey and
detection program.
The ECB survey has been
conducted in Delaware cornfields
every fall since 1936. At that tune

problems related to the production
and propagation of rhododendrons,
azaleas and dogwoods.
In cooperation with Richard W.
Lighty, former coordinator of the
Longwood graduate program in
botanical garden management,
Dunham helped plan and establish
the college’s Clark Garden. Made
possible by a gift from Emily Clark
Dieffenbach, this features an
extensive collection of woody
landscape plants well adapted to
Delaware growing conditions. The
garden was dedicated in 1973 and
today is used primarily as a
teaching tool for ornamental
horticulture students.
30 sites were selected, 10 in each
county. Each year University
entomologists examine the corn
field nearest each original site for
borer infestation.
This survey is useful because it
provides an estimate of the
overwintering corn borer
population. Growers can then use
this information in planning the
next year’s cropping activities.
Results of the 1984 survey will be
available later this fall.
