fall colors appear. Applications in spring or early summer,
before  flowering, have been less effective. Repeat
applications may be needed. One application may merely
suppress Virginia Creeper. (See warnings in the "Tree
Fruit Herbicide Recommendations" section of this
bulletin.)
Broadcast:4 - 5 lb ai/A. Use 4 - 5 qt/A Roundup
Ultra 4SC.
Spot treatment:2 - 5% solution. Use 2 - 5 gal of
Roundup Ultra 4SC/100 gal spray solution. Wet weed
foliage as thoroughly as possible. Use the 2% solution
when 100 percent of the weed foliage can be wet. Use up
to a 5% solution when only partial wetting of the weed
foliage is possible. Wet a minimum of 50 percent of the
weed foliage for effective control.
Ropewick:Not recommended; creeping nature of plant
is difficult to wipe.
For newly planted (nonbearing) apples, peaches,
pears, plums, and cherries.
For established apples, peaches, pears, plums, and
cherries.
2,4-D - 1 lb ai/A. Use 1 qt/A Weedar 64. Apply in
July to weed foliage. Do not spray fruit tree foliage or
green bark. Will provide suppression only. May be
tank-mixed with residual herbicides. Do NOT tank-mix
with Paraquat/Gramoxone or control may be reduced.
For established (bearing) apples, pears, peaches,
plums and cherries.

Weeds are perennials that begin growth in April from
rosettes or rootstocks. Typically, blooms are about _
inch in diameter. The flowers have white or slightly
tinted purple petals with yellow centers. They appear in
late summer, set seed, and the stems die in the fall.
Some regrowth, as short stems or rosettes, often occurs
before winter. The weed spreads using underground
horizontal roots. Once established, control of this weed is
difficult since it is tolerant to most herbicides and the
roots can be spread by cultivation or other tillage
practices.
Roundup Ultra 4SC (glyphosate). Apply in May
or June after spring growth is at least 8 to 10 inches tall,
but before the shoots become too tall for good coverage
with the spray solution. Generally, broadcast sprays must
be applied in May, while spot treatments and ropewick
applications can be delayed until June. (See warnings in
the "Tree Fruit Herbicide Recommendations" section.)
Broadcast:2 - 4 lb ai/A. Use 2 - 4 qt/A Roundup
Ultra 4SC.
Spot Treatment: 2% solution. Use 2 gal Roundup
Ultra 4SC/100 gal spray solution. Apply to wet the
foliage to the drip point.
Ropewick Applicator:Wipe twice; travel in
opposite direction for each wipe.
For newly planted (nonbearing) apples, peaches,
pears, plums, and cherries.
For established (bearing) apples, peaches, pears,
plums, and cherries.
