LATE BLIGHT “ALERT”
This is the second in a series of
articles on diagnosing and reduc
ing pests in the garden. Serious
disease and insect pests problems
require quick identification and
treatments.
During the growing season,
check your garden weekly for dis
eases. On potatoes and tomatoes
check weekly especially in wet
weather.
Why? A disease known as late
blight can affect the foliage, fruits
and tubers of tomato and potato.
The first occurrence of late blight
in any area will be very important
to other areas where late blight has
not appeared. Please contact your
County Extension Office, if you
suspect the presence of late blight
The “alert” is also for commer
cial growers of both potato and to
mato. There is a strong chance that
potato seed pieces in cull piles
could be carrying the blight fun
gus (Phytophthora infestans).
Tomatoes and potatoes are sus
ceptible to late blight at any time
during the growing season. If the
growing season continues wetter
than the usual, late blight occur
rence is likely.

If you find late blight, begin
fungicide applications. Or inten
sify your fungicide applications
by increasing application frequen
cy or rate. Be sure to keep within
the guidelines on the pesticide la
bel.
The only fungicides now ef
fective against late blight and
available to home gardeners are
protectant materials. These pro
ducts protect foliage from infec
tion but they cannot cure plants
once they are infected. Continu
ous fungicide coverage is neces
sary to protect plants from infec
tion.
Protectant fungicides available
to manage the disease include
mancozeb, maneb, chlorothalonil,
and copper. See the label direc
tions for specific information on
application rates and frequency of
application.
If late blight becomes severe,
remove diseased plants by digging
them up. Destroy these plants im
mediately by burying in an area
away from the garden, or discard
ing in a plastic bag. Lastly, harvest
all potato tubers in the garden. If
late blight occurs when the tubers
have already “sized up,” harvest

Governor’s School For Ag
Sciences Marks 10th Year
UNIVERSITY PARK (Centre
Co.) —The Pennsylvania Gover
nor’s School for the Agricultural
Sciences at Penn State, held on the
University Park Campus July 2 to
August 5, celebrates its 10th
anniversary this year.
Each summer. 64 of the state’s
leading high school juniors and
seniors spend five weeks at Penn
State, learning about the agricul
tural sciences. They conduct
research with professors and have
access to college facilities, includ
ing specialized libraries and
laboratories.
Over the past 10 years, about
600 students have attended the
the crop as soon as possible to
avoid post-harvest tuber rot.
Again, destroy diseased foliage
and stems.
Watering practices that help re
duce foliage diseases will help
prevent late blight On potatoes
and tomatoes avoid wetting the
leaves when you water. How?
Soak the ground around each plant
instead of spraying the foliage
with water. Consider using a trick
le irrigation system or water your
garden mid-day so that the foliage
dries off quickly. Eliminate weeds
around the garden so as to maxi
mize air circulation around the
plants. Additionally for potatoes,
hill up the soil around the plants to
provide a more substantial barrier
against tuber infection from
spores washing down through the
soil.

projects.
They also take field trips to
agricultural agencies and busines
