3. Do NOT apply to grasses suffering from drought,
   heat, cold, or any other stress condition.
   For newly planted (nonbearing) apples, peaches,
   pears, plums, and cherries.For established
   (bearing) peaches, nectarines, cherries, and plums.

Kerb (pronamide)--2 - 4 lb ai/A.Use 4 - 8 lb/A
Kerb 50WP. Apply in November when soil temperatures
are between 35^oand 55^oF (1.67^oand 12.8⁰C). Primarily
controls perennial grasses, including quackgrass,
bluegrass, ryegrass sp., fescue sp., and also provides early
control of annual grasses the following spring.
Apply Surflan, Prowl, Solicam, or Sinbar the
following May or June for full season annual grass
control. Tank-mix Kerb with 2, 4-D and Princep for
postemergence and residual broadleaf weed control.
For established (bearing) apples, peaches, pears,
plums, and cherries.

Poast (sethoxydim)--0.2 - 0.5 lb ai/A. Apply 1 -
2.5 pt/A Poast 1.53EC. Add 2 pints crop oil concentrate
per acre. Use the lower rate to control annual grasses less
than 6 inches tall. Use the higher rate to control annual
grass 6 to 12 inches tall and to control perennial grasses.
Do NOT tank-mix Poast with any other pesticide.
Do NOT apply within 1 hour of rainfall.
Do NOT apply to grasses suffering from drought,
heat, cold, or any other stress condition.
Poast is currently LABELED for NONBEARING
FRUIT TREES only. Do NOT apply within 12 months
of harvest.
For newly planted (nonbearing) apples, peach, pears,
plums, and cherries.
For established (bearing) apples and pears

Nonselective

Gramoxone Extra (paraquat)--0.5 lb ai/A.Use
0.8 qt/A Gramoxone Extra 2.5SC. Contact killer only; no
translocation or residual activity. Best results occur when
weeds are 6 inches tall or less. Regrowth may occur from
the root systems of established weeds. Use a surfactantto
be 0.25% of the spray solution (1 qt. per 100 gallons of
spray solution). Combine with recommended
preemergence herbicide(s) for residual weed control. Do
not allow spray or drift to contact green bark, leaves, or
fruit. Crop damage may result. DANGER; Do not
breathe spray mist. Read safety precautions on the
label.
For newly planted (nonbearing) apples, peaches,
pears, plums, and cherries.
For established (bearing) apples, peaches, pears,
plums, and cherries.

Roundup Ultra 4SC(glyphosate)will control many
serious annual and perennial weeds in orchards. It is a
translocated slow-acting herbicide with no soil or residual
activity. Results will become evident 1 to 3 weeks after
application. Optimum rate and time of application depend
on weed species and growth stage. Weeds should be

growing vigorously when treated. Do not treat weeds that
are under stress from drought, extreme heat , cold, or
other adverse growing conditions.
Broadcast:0.75-5 lb ai/A. Use 0.75-5 qt/A
Roundup Ultra 4SC. Apply lower rates, 0.75-1 qt/A, to
control seedlings and annual weeds and to suppress
established perennial weeds. See warnings below.
Labeled for peach and plum in New Jersey only.
Spot treatment: 1-2% solution. Use 1-2 gal Roundup
Ultra 4SC/100 gal water. Wet weed foliage thoroughly.
See warnings below. Labeled for peach and plum in New
Jersey only.
Ropewick applicator:Mix Roundup Ultra 4SC and
water at a 1:2 ratio (1 part Roundup Ultra 4SC to 2 parts
water) and fill pipe only one-half full to prevent excessive
dripping. One gallon of Roundup Ultra 4SC will wipe 10
to 100 acres, depending on weed density. Repeated
wiping may be needed to provide control equal to
broadcast or spot applications. TheRopewick applicator
offers significant herbicide cost savings. See paper on
Ropewick applicator construction and use warnings
below.
WARNINGS
1.Do NOT allow Roundup Ultra 4SC to contact the
leaves, young green bark, fresh trunk wounds, or
root suckers, or severe crop injury may occur.
2.Do NOT allow Roundup Ultra 4SC to contact
ANY IMMATURE PART of PEACH or PLUM
trees.
3.Do NOT use GALVANIZED containers.
Roundup Ultra 4SC will react with the container
to produce explosive hydrogen gas.
For newly planted (nonbearing) apples, peaches,
pears, plums, and cherries.
For established (bearing) apples, peaches, pears,
plums, and cherries.

Problem Weeds

less than 2 full years. The plant often grows vegetatively
during the first year, then flowers and dies during the
second year.
Perennial.A weed that lives longer than 2 full years,
often reproducing vegetatively by horizontal shoots, roots,
or rhizomes, as well as by seed.
Complete weed control (eradication) of any weed is
difficult or impossible. Established perennial weeds are
among the most difficult to kill. One application of an
herbicide recommended below may not provide complete
control, but regrowth should be limited and competitive
ability reduced. Follow-up spot treatments will improve
the long-term result of the initial herbicide application.
