DIRECTIONS FOR USE
It is a violation of federal law to use this product in a
manner inconsistent with its labeling.
DuPontrm LANDMARK(! XP should be used only in
accordance with recommendations on this label or in
separately published DuPont recommendations.
DuPont will not be responsible for losses or damages
resulting from the use of this product in any manner not
specifically recommended by DuPont. User assumes all
risks associated with such nonrecommended use.
GENERAL INFORMATION
LANDMARK , A) XP herbicide is a dispersible granule that is
mixed in water and applied as a spray.
LANDMARKR) XP controls many annual and perennial
grasses and broadleaf weeds in non -crop sites.
LANDMARKR? XP may be used for general weed control
on terrestrial non -crop sites and for selective weed control
in certain types of unimproved turf grasses on these same
sites. LANDMARKA) XP can be tank mixed with other
herbicides registered for use in non -crop sites; when tank
mixing. use the most restrictive limitations from the labeling
of both products.
Do not apply more than 6.0 ounces active ingredient
sulfometuron methyl per acre per year when using this
product or any other product containing sulfometuron
methyl.
Do not apply more than 2.25 ounces active ingredient
chlorsulfuron per acre per year when using this product or
any other product containing chlorsulfuron.
LANDMARK0 XP controls weeds by both preemergence
and postemergence activity. 'The best results are obtained
when the application is made at or before the early stages of
weed growth, before weeds develop an established root
system. Moisture is required to move LANDMARKH) XP
into the root zone of weeds for preemergence control.
This product may be applied on non -crop sites that contain
areas of temporary surface water caused by collection of
water in equipment ruts, or in other depressions created by
management activities. It is permissible to treat intermit-
tently flooded low lying areas, seasonal dry Flood plains and
transitional areas between upland and lowland areas when
no water is present. It is also permissible to treat marshes,
swamps and bogs after water has receded, as well as
seasonally dry flood deltas. DO NOT make applications to
natural or man -made bodies of water such as lakes,
reservoirs, ponds, streams and canals.
A drift control agent may be used at the manufacturer's
recommended rate in the application of LAN DMARK:R; XP.
LANDMARK0 XP is noncorrosive, nonflammable,
nonvolatile and does not freeze.
For best postemergence results, apply LANDMARK:k XP
to young, actively growing weeds. The degree and duration
of control may depend on the following:
• weed spectrum and infestation intensity
• weed size at application
• environmental conditions at and following treatment
• soil pH, soil moisture, and soil organic matter
Note:
Do not exceed a rate of 9.0 ounces of LANDMARK(R) XP
per acre per year.
Do not use on food or feed crops.
Do not enter or allow others to enter the treated area until
sprays have dried.
ENVIRONMENTAL CONDITIONS
AND BIOLOGICAL ACTIVITY
When applied as a spray, LANDMARKK? XP is absorbed
by both the roots and foliage of plants, rapidly inhibiting the
growth of susceptible weeds. When applied on dry fertilizer,
LANDMARKR) XP is absorbed primarily by the roots. Two
to three weeks after application to weeds, plant growth
slows, and the growing points turn reddish - purple. Within 4
to 6 weeks of application, leaf veins and leaves become
discolored, and the growing points subsequently die.
Warm, moist conditions following application accelerate the
herbicidal activity of LAN DMARK0 XP; cold, dry
conditions delay the herbicidal activity. In addition, weeds
hardened -off by drought stress are less susceptible to
LANDMARKO XP. Moisture is needed to move
LANDMARKR> XP into the soil for preemergence weed
control.
RESISTANCE
When herbicides that affect the same biological site of
action are used repeatedly over several years to control the
same weed species in the same field, naturally- occurring
resistant biotypes may survive a correctly applied herbicide
treatment, propagate, and become dominant in that field.
Adequate control of these resistant weed biotypes cannot be
expected. If weed control is unsatisfactory, it may be
necessary to retreat the problem area using a product
affecting a different site of action.
To better manage herbicide resistance through delaying the
proliferation and possible dominance of herbicide resistant
weed biotypes, it may be necessary to change cultural
practices within and between crop seasons such as using a
combination of tillage, retreatment, tank -mix partners
and/or sequential herbicide applications that have a different
site of action. Weed escapes that are allowed to go to seed
will promote the spread of resistant biotypes.
It is advisable to keep accurate records of pesticides applied
to individual fields to help obtain information on the spread
and dispersal of resistant biotypes. Consult your
agricultural dealer, consultant, applicator, and/or appropriate
state agricultural extension service representative for
specific alternative cultural practices or herbicide
recommendations available in your area.
