Scout early for anthracnose signs
BLOOMINGTON, m. -
Periods of extended rainy
weather in the spring and
fall are the most likely times
for anthracnose to strike. It
stands to reason that those
are also the best times to be
in your com fields checking
for the presence of the
disease.
Anthracnose is becoming
an increasingly significant
disease in the eastern Com
Belt. It has been identified in
states east of the Mississippi
River, the central Com Belt

Caused by the fungus,
Coletotricum gramimcola,
anthracnose ranks along
with Diplodia and Gibberella
stalk rot as some of the most
economically important of
the reoccurnng corn
diseases.
The anthracnose fungus
may first attack seedlings in
the spring; when the plants
are about six inches tall,

manager of pathology and

entomology research for
Funk Seeds International.
This leaf-blighting stage of
anthracnose appears as
yellow or yellow-bordered
lesions of one-quarter to one
half inch m diameter,
generally on the lower
leaves.
“These early lesions do not
cause much economic
damage,” says Turner,
“because they are not as
important to photosynthate
production. However, if wet
weather persists throughout
the summer, anthracnose
can also persist, causing
some decrease in yield. ”
This does not occur very
frequently, he adds.
But the presence of earlier
lesions can spell trouble
later in the season as they
create a stress on the plant.
When the weather turns
damp again in the early fall,
anthracnose sometimes
manifests itself through top
lodging. Often confused with
com borer feeding, an
thracnose can be
distinguished by the narrow,
vertical or oval lesions on
the stalk rind.
These lesions are tan to
reddish-brown, turning dark
brown or black with age. The
lesions can grow together,
producing large blotchy
areas.
According to Turner, an
early infection of an
thracnose often weakens the
plant, opening it to other

stalk rot organisms which
can choke off the plant’s
ability to translocate
nutrients to the ear.
The disease, when com
bined with other diseases in
the stalk rot complex, can
also cause serious lodging
problems.
The disease is fast-acting,
says Turner, who points out
the importance of frequent
scouting for the disease in
the fall.
The most effective control
for anthracnose is planting
resistant hybrids, according
to Turner.
“We inoculate our
breeding lines with an
thracnose, and those which
appeal particularly
susceptible are eliminated
from further hybrid con
sideration,” he says.
Funk conducts an
thracnose screening
programs at several
locations in the areas where
the disease is most
troublesome.
“While we have some
hybrids that are more
resistant than others, I’m
not aware of anyone who has
a hybrid that is totally im
mune,” he says. Turner
suggests that growers
consult theu- seed dealers for
recommendations on
resistant hybrids adapted to
their area.
Turner adds that clean fall
plowing provides insurance
against the disease because
the fungus can overwinter on
crop debris. Crop rotation
may also reduce the seventy
of the disease if reduced
tillage practices are em
ployed for rolling or hilly
topography.
If the disease is identified
early in the fall, quick
harvest may help minimize
losses due to lodging, says
Turner.
But he reiterates that
resistant hybrids are the
best protection against the
disease.
“With the testing
procedures we use, I feel
optimistic about getting
ahead of these organisms.”
