UNIVERSITY PARK (Centre
Co.) Spring is a lime when
many people enjoy the blooms of
ornamental trees and shrubs. But
one popular flowering tree is dis
appearing from many landscapes.
Since the late 19705, dogwood
trees native to the eastern United
States have suffered from stress
and disease. The resulting decline
in dogwood health and popula
tions has made the plant’s specta
cular white floral display a rare
sight in some areas.
“Scientists believe the primary
cause is a fungus called Discula,”
says Dr. Gary Moorman, associate
professor of plant pathology in
Penn State’s College of Agricul
tural Sciences.
“It’s thought that the fungus
was inadvertently brought to the
U.S. in the 19705,” he says. “It
since has spread throughout the
range of the native dogwoods. Be
cause these trees have never be
fore been exposed to the fungus,
they are especially susceptible to
attack.”
The area affected by the decline
ranges from southern Maine to
northern Alabama. Trees in ex
posed sites seem most susceptible,
but forest dogwoods also are dy
ing.
Several symptoms are charac
teristic of dogwood decline.

502 T Pull-Type Sprayer
Establishing quality standards in pull-type sprayers began over 20 years ago
with the Ag Chem Modef 402 sprayer, and today the Model 502 T is carrying
on the tradition. With a formed steel channel frame for extra durability and a
tongue that attaches directly to the axle for maximum pulling strength, the
chassis of the 502 T is a rugged performer Axle choices include the single
configuration or, for maximum stability, the tandem axle design. Axles are row
crop adjustable from 60 inches to 80 inches and wheel hubs are the 6-bolt type.
Wheel rims (I0”x 15”) and tires (11 Lx 15,6-ply) are also available.
Standard features for this sprayer include a loading platform and a 2,000 lb
rated longue jack. Boom Options: • 45' Hydraulic Fold & Level Boom
SK4OO Skid-Mount Sprayer
The Ag Chem SK4OO Skid-Mounted Sprayer is an ideal system for a custom
operator who wants to cover acres fast and efficiently It easily slides in and out
of a standard pickup bed and is recommended for use with 3/4 ton or larger
vehicles. When the unit is not being used, it rests on four conveniently built-in
leg stands.
Our 4TA foot suspension boom features our unique 3 section quick-fold
system (manually operated) and breakaway boom arms that automatically
return to the spraying position after striking an obstruction. The boom is crop
height adjustable, and its arms fold forward to rack along the side of the pickup
bed. Hydraulic options include boom leveling and our new boom fold system.

Dogwoods Disappearing From Landscapes
Twigs and lower branches die.
Cankers, or abnormally roughen
ed areas, form on twigs, branches
and trunks. Dogwood borers at
tack the weakened tree. Water spr
outs develop at the tree’s base,
then die. Tree growth sloWs.
Eventually, the tree may die.
Discula is one of several fungi
that cause a disease known as an
thracnose. “It can produce brown
spots up to one-fourth-inch in dia
meter on leaves,” Moorman says.
“Smaller, reddish-brown spots
may pepper portions of the leaf or
extend along veins.
“Large brown blotches of dead
tissue may appear on leaf tips,
along the margin of leaves or be
tween the veins,” he says. “Leaves
on branch tips may be completely
blighted and stay attached over
winter. Lower twigs and branches
may die.”
The fungus overwinters in in
fected twigs and leaves that re
main on the tree and in infected
fallen leaves.
“This fungus also has been
found on dogwood seeds,” says
Moorman. “Studies are under way
to determine whether migrating
songbirds are eating infected
seeds, then spreading the fungus
along their migration routes. Re
searchers also are looking at pos
sible insect transmission of the
