ENVIRONMENTAL CONDITIONS
AND BIOLOGICAL ACTIVITY
DIRECTIONS FOR USE
It is a violation of federal law to use this product in a manner
inconsistent with its labeling.
VELPAR L is absorbed through the roots and foliage.
Moisture is required to activate VELPAR L in the soil. Best
results are obtained when the soil is moist at the time of
application and 1/4–1/2" of rainfall occurs within 2 weeks
after application.
VELPAR L should be used only in accordance with recommen-
dations on this label, or in supplemental DuPont publications.
Do not apply this product in a way that will contact workers or
other persons, either directly or through drift. Only protected
handlers may be in the area during application. For any
requirements specific to your state or tribe, consult the agency
responsible for pesticide regulation.
Apply VELPAR L preemergence or postemergence when weeds
are less than 2" in height or diameter. Foliar activity is most
effective under conditions of high temperature (above 80 °F),
high humidity, and good soil moisture. Foliar activity may be
reduced when vegetation is dormant, semi-dormant, or under
stress.
The correct use rates by crop and geographical area,
specified on this label, and proper mixing/loading site
considerations and application procedures must be followed
to minimize potential for hexazinone movement into ground
water. Users are encouraged to consult with their state
Department of Agriculture, Extension Service, or other
pesticide lead agency for information regarding soil
permeability, aquifer vulnerability, and best management
practices for their area.
On herbaceous plants, symptoms usually appear within 2 weeks
after application under warm, humid conditions, while 4–6
weeks may be required when weather is cool or dry, or when
plants are under stress. If rainfall after application is inadequate
to activate VELPAR L in the soil, plants may recover from
contact effects and continue to grow.
On woody plants, symptoms usually appear within 3–6 weeks
after sufficient rainfall has carried the herbicide into the root
zone during periods of active growth. Defoliation and refoliation
may occur, but susceptible plants are killed.
AGRICULTURAL USES
AGRICULTURAL USE REQUIREMENTS
Use this product only in accordance with its labeling and
with the Worker Protection Standard, 40 CFR part 170.
This Standard contains requirements for the protection of
agricultural workers on farms, forests, nurseries, and
greenhouses, and handlers of agricultural pesticides. It
contains requirements for training, decontamination, notifi-
cation, and emergency assistance. It also contains specific
instructions and exceptions pertaining to the statements on
this label about personal protective equipment(PPE) and
restricted-entry interval. The requirements in this box only
apply to uses of this product that are covered by the Worker
Protection Standard.
The degree and duration of control may depend on the following:
• Use rate
• Weed spectrum and size at application
• Environmental conditions at and following treatment
Where a rate range is shown, use the higher levels of the dosage
range on hard-to-control species, fine-textured soils, or soils
containing greater than 5% organic matter or carbon. Use the
lower levels of the dosage range on coarse-textured soils and/or
on soils low in organic matter. Refer to specific uses for rate
ranges.
WEED RESISTANCE MANAGEMENT
Do not apply this product in a way that will contact workers
or other persons, either directly or through drift. Only
protected handlers may be in the area during application.
When herbicides with the same mode of action are used
repeatedly over several years to control the same weed species
in the same field, naturally occurring resistant weed biotypes
may survive a correctly applied herbicide treatment, propagate,
and become dominant in that field. These resistant weed
biotypes may not be adequately controlled. Cultural practices
such as tillage, preventing weed escapes from going to seed, and
using herbicides with different modes of action within and
between crop seasons can aid in delaying the proliferation and
possible dominance of herbicide resistant weed biotypes.
Do not enter or allow worker entry into treated areas during
the restricted entry interval(REI) of 24 hours.
PPE required for early entry to treated areas that is
permitted under the Worker Protection Standard and that
involves contact with anything that has been treated, such as
plants, soil, or water, is :
Coveralls
Waterproof gloves
Shoes plus socks
Protective eyewear
APPLICATION INFORMATION
VELPAR L may be applied by ground equipment and, where
permitted, aerial equipment. Use rates, minimum spray
gallonage, and other application information are described for
the various uses.

REPLANTING (FOLLOWING ALFALFA)
• Do not replant treated areas to any crop except corn, root
crops or sugarcane within two years after treatment, as crop
injury may result.
Injury may result to alfalfa plants that fail to meet these
growth criterion listed above.
• Do not use VELPAR L on seedling alfalfa, alfalfa-grass
mixtures, or other mixed stands as injury may result to the
seedling alfalfa or companion crop.
• Corn may be planted 12 months after the last treatment,
provided the use rate did not exceed 3 pt per acre, except in
areas of low rainfall (20" or less).
• At elevations above 4,000 ft, do not use VELPAR L on
alfalfa that has been established with a cover or nurse crop
until the alfalfa has gone through two summer growing
seasons.
• Root crops such as potatoes, sugarbeets, radish and carrots
may be planted 12 months after last treatment, provided the
use rate not exceed 2 pt per acre. Sites with use rates
higher than 2 pt per acre should not be replanted to any
crop within 2 years of application, or unacceptable crop
injury may result.
• Do not use VELPAR L in low desert valleys in California
or Arizona.
• Sugarcane may be planted any time following treatment.
• Do not exceed 3 pt per acre on alfalfa less than one year
old.
• In California, do not replant seed alfalfa areas to any crop
within two years after treatment, as crop injury may result.
• Do not add a surfactant to VELPAR L when treating
nondormant alfalfa varieties.
IMPORTANT PRECAUTIONS - ALFALFA ONLY
• Do not use VELPAR L on gravelly or rocky soils, exposed
subsoils, hardpan, sand, poorly drained soil, or alkali soils.
Best results are obtained when 1/2–1" of rainfall or sprinkler
irrigation occurs within two weeks after application, when
soil is moist at time of application, and when weeds have not
germinated or are less than 2" in height or diameter. Heavy
rainfall or excessive irrigation after application may result in
crop injury or poor performance of the herbicide.
• Crop injury, including mortality, may result in fields with
restricted root growth due to nonuniform soil profiles
such as gravel bases and clay lenses.
• Do not graze or feed forage or hay to livestock within 30
days following application.
• Do not apply to snow-covered or frozen ground.
• On soils high in organic matter (greater than 5%), the
effectiveness of VELPAR L can be significantly reduced
and weed control may be unsatisfactory.
SEED ALFALFA (CALIFORNIA ONLY) -
ADDITIONAL PRECAUTIONS
• Do not use VELPAR L on fields with sandy loam or
loamy sand soils having less than 1% organic matter.
• Since the effect of VELPAR L on alfalfa varies with soil
conditions, uniformity of application, and environmental
conditions, growers should limit their first use to small
areas.
• Do not exceed 2 pt per acre on fields with sandy loam or
loamy sand soils having 1–2% organic matter.
• Do not exceed 2 pt per acre on seed alfalfa that has been
established for only one growing season.
• If abnormally dry conditions exist following application,
restrict the first irrigation to no more than 1/2 acre inch of
water.
ALFALFA - IMPREGNATION ON
DRY BULK FERTILIZER (EXCEPT
CALIFORNIA AND ARIZONA)
• Temporary yellowing of alfalfa may occur following
VELPAR L applications.
• Treat only stands of alfalfa established for one year or for
one growing season(except in California), provided the
following conditions are met:
Dry bulk fertilizer may be impregnated or coated with
VELPAR L for application to established alfalfa. All
recommendations, cautions and special precautions on this
label must be followed along with state regulations relating to
dry bulk fertilizer blending, impregnating and labeling. Keep
VELPAR L from heat, sparks, and open flame. (Refer to the
material safety data sheet [MSDS] for VELPAR L.)
–The alfalfa root system must be well established.
–The crop must be healthy, vigorous and not under stress
from adverse weather conditions, insect or disease
damage.
–The alfalfa crop must be free of excessive winter injury
from freezing and thawing.
If fertilizer materials are excessively dusty, use a suitable
additive to reduce dust prior to impregnation, as dusty
fertilizer will result in poor distribution during application.
The dry fertilizer must be properly impregnated and
uniformly applied to the alfalfa to avoid crop injury and/or
poor weed control.
• In California, fall planted alfalfa may be treated in the
following winter months with VELPAR L at 1 to 2 pts per
acre to suppress or control Black Mustard, Common
groundsel, London rocket, Shepard’s-purse, Common
chickweed, Fiddleneck or Filaree, provided:
To impregnate the fertilizer, use a system consisting of a
conveyor or closed drum used to blend dry bulk fertilizer. Any
commonly used fertilizer can be impregnated with VELPAR
L, except potassium nitrate or sodium nitrate. Do not use
VELPAR L on limestone.
- alfalfa root growth exceeds 6 inches in length
- vegetative top growth of alfalfa has lateral development of
secondary growth
4
Use a minimum of 250 lb dry bulk fertilizer per acre and up to Do not use VELPAR L on Christmas trees in the following
a maximum of 450 lb per acre. To impregnate or coat the dry
bulk fertilizer with VELPAR L, direct the nozzles to deliver a
fine spray towards the fertilizer for thorough coverage while
avoiding spray contact with mixing equipment. Uniform
impregnation of VELPAR L to dry bulk fertilizer will vary,
and if the absorptivity is not adequate, the use of an
absorptive powder may be required to produce a dry, free-
flowing mixture. Microcel E (Johns Manville Product
Corporation) is the recommended absorbent powder. When
another herbicide is used with VELPAR L, mix and
impregnate the fertilizer immediately.

• Within 180 days of harvest in Hawaii.
• Within 234 days of harvest in Louisiana.
• Within 288 days of harvest in Puerto Rico.
• Within 234 days of harvest in Texas.
Snowbelt (areas of low spring rainfall): For best results, apply
in the fall before soil freezes, or in the spring after snow cover
melts in anticipation of rainfall. Weed and brush control results
from spring applications will be dependent on sufficient rainfall
following application to activate VELPAR L.
To avoid injury to sugarcane, observe the following precautions:
USE RATES
• Do not use VELPAR L on cane that shows poor vigor because
of insect damage, disease, or winter injury, or shows
symptoms of other stress conditions such as drought stress.
Use the lower rates on coarse-textured soils and soils low in
organic matter; use the higher rates on fine-textured soils and on
soils high in organic matter. Use the higher rates where hard-to-
kill species predominate.
• Do not add a surfactant in applications unless otherwise
specified or allowed.
The rates listed below are for broadcast application.

Apply VELPAR L plus GARLON 4 from late spring to early
summer after the trees have reached full leaf, but before leaf
tissue hardens.
SINGLE STEM (BASAL SOIL)
Apply undiluted VELPAR L to the soil with an exact
delivery handgun applicator. Apply at the rate of 2–4 ml for
each inch of stem diameter at breast height. Direct the
treatment to the soil within 3 ft of the root collar of woody
plants to be controlled. When treating large stems and when
more than one delivery of VELPAR L is needed per stem,
make application on opposite sides of the stem.
USE RATES
Refer to the use rate table in the Site Preparation section of
this label for recommended rates of VELPAR L based on
soil texture. Mix the recommended rate of VELPAR L with
4–8 qt of GARLON 4 per acre.
SPRAY EQUIPMENT
For multi-stemmed and low-growing brush that have stem
diameters that are difficult to determine, apply VELPAR L
at the rate of 2–4 ml per 3" of canopy width. For tall,
slender (columnar) brush types, apply 4–8 ml per 3" of
height. Base the rate on whichever canopy dimension is
greater (width or height).
Apply VELPAR L plus GARLON 4 by ground equipment
or by air (helicopter only).
MIXING INSTRUCTIONS
For ground application, use enough water for thorough
coverage, usually a minimum of 25 gal per acre. For aerial
applications, use at least 12 gal of water per acre.
When treating brush that requires more than a single 4 ml
application of VELPAR L, apply subsequent applications
equally spaced around the plant. If treating brush on sloped
sites, apply most of the VELPAR L on the uphill side of the
stem. If treating resprouts from brush disturbed by cutting
or shredding, the rate of application should be proportional
to the original tree size, not just the small regrowth of
sprouts.
For best results, full foliar coverage is required.
IMPORTANT PRECAUTIONS
- VELPAR L + GARLON 4
• Conifers planted sooner than two months after treatment
with GARLON 4 at 1–2 gal per acre may be injured.
• Burning treated sites after initial contact (browning) effect
on foliage may result in poor control. Burn the vegetation
only after brush has completely defoliated at least once,
allowing sufficient root uptake of VELPAR L (usually 60-
90 days after adequate rainfall).
INJECTION
No Worker Protection Standard worker entry
restrictions or worker notification requirements apply
when this product is directly injected into agricultural
plants.
• Before using GARLON 4, read and carefully observe the

APPLICATION TIMING
IMPORTANT PRECAUTIONS - FORESTRY
• Do not use VELPAR L in nurseries, seedbeds, or ornamental
plantings.
EASTERN US
Apply VELPAR L as a broadcast or banded spray in the spring
prior to conifer bud break to lessen conifer injury potential.
• On tracts of land where various soil types are present and
VELPAR L rate selection is difficult, conifer damage or less-
than-expected vegetation suppression may occur due to the
different rates required for various soil types.
WESTERN US
Rainbelt (areas of high spring rainfall): For best results, apply
as a broadcast or banded spray in the late winter or spring when
weeds are actively growing, but prior to conifer budbreak.. If
application is made after conifer bud break, use directional spray
equipment to prevent contact with conifer foliage, as injury may
result.
• Poor weed and brush control may result from the following:
–Heavy duff or slash present at time of application
–Use on poorly drained sites
–Applications made when the soil is saturated with water and
rain is imminent within 24 hours.
Snowbelt (areas of low spring rainfall): For best results, apply
as a broadcast or banded spray in the fall before soil freezes and
after the final resting bud has hardened on the conifers. Or,
spring applications may be made after snow cover melts in
anticipation of rainfall prior to conifer budbreak. Weed control
results from spring treatments will be dependent on sufficient
rainfall following application to activate VELPAR L.
–Applications to soils high in organic matter (greater
than 5%).
• Following harvest, allow stumps and injured trees sufficient
time to adequately resprout before applying VELPAR L.
• Where burning is desired, burn vegetation only after any
brush has completely defoliated, at least twice, allowing for
sufficient root uptake of VELPAR L
USE RATES
The rates listed below are for broadcast application. For band
application, use proportionately less. For example, use 1/2 of the
broadcast rates when treating a 3-ft band where row spacing is 6
ft.
• Do not use VELPAR L on frozen soils; use in spring after
snow melt.
• Do not add a surfactant in applications over the top of
conifers.

IMPORTANT PRECAUTIONS
- INDUSTRIAL UNIMPROVED TURF
• Use VELPAR L only in stands of bermudagrass and
bahiagrass established for at least one year. Do not treat newly
sprigged or sodded areas.
Undiluted - Apply VELPAR L undiluted with an exact-
delivery handgun applicator. This equipment delivers a thin
stream of a predetermined volume when triggered. Apply
VELPAR L at the rate of 2–4 ml for each inch of stem
diameter at breast height. Do not exceed 4 gal of VELPAR L
per acre per year. Direct the treatment to the soil within 3 ft of
the root collar of woody plants to be controlled. When treating
large stems and when more than one delivery of VELPAR L is
needed per stem, make applications on opposite sides of the
stem.
• Some discoloration of the bermudagrass or bahiagrass may
occur after application.
• Injury may result when desirable grasses are under stress from
drought, insects, disease, cold temperature, or poor fertility.
• Severe turf injury may occur if applications are made on
gravelly or rocky soils, thinly covered subsoils, or soils with
less than 1% organic matter.
For multi-stemmed and low-growing brush that have stem
diameters that are difficult to determine, apply VELPAR L at
the rate of 2–4 ml per 3" of canopy width. For tall, slender
(columnar) brush types, apply 4–8 ml per 3" of height. Base
the rate on whichever canopy dimension is greater (width or
height).
BRUSH CONTROL
VELPAR L is recommended for the control of undesirable
woody plants in noncrop sites.
APPLICATION TIMING
Apply VELPAR L from late winter through summer, prebud
break until new growth hardens off.
When treating brush that requires more than a single 4 ml
application of VELPAR L, apply subsequent applications
equally spaced around the plant. If treating brush on sloped
sites, apply most of the VELPAR L on the uphill side of the
stem. If treating resprouts from brush disturbed by cutting or
shredding, the rate of application should be proportional to the
original tree size, not just the small regrowth of sprouts.
In areas where the soil remains frozen during the winter and
spring rains are usually inadequate for soil activation, a fall
or winter treatment may be applied before the soil freezes.
WOODY PLANTS CONTROLLED - USE RATE

IMPORTANT PRECAUTIONS - PASTURE
SPRAY EQUIPMENT
AND APPLICATION TECHNIQUES
• Use VELPAR L only in stands of bermudagrass and
bahiagrass established for at least one year. Do not treat newly
sprigged or sodded areas.
Basal (Soil) Undiluted - Apply VELPAR L undiluted with an
exact-delivery handgun applicator. This equipment delivers a
thin stream of a predetermined volume when triggered. Apply
VELPAR L at the rate of 2–4 ml for each inch of stem
diameter at breast height. Do not exceed 1/3 gal of VELPAR L
per acre per year. Direct the treatment to the soil within 3” of
the root collar of woody plants to be controlled. When treating
large stems and when more than one delivery of VELPAR L is
needed per stem, make applications on opposite sides of the
stem.
• Some temporary discoloration of the bermudagrass or
bahiagrass may occur after application.
• Treatment of mixed pastures containing forage species other
than bermudagrass or bahiagrass may result in injury or
mortality to the other forage species.
• Injury may result when desirable grasses are under stress from
drought, insects, disease, cold temperature, or poor fertility.
• Injury to or loss of desirable trees or other plants may result if
VELPAR L is applied or if equipment is drained or flushed
on or near desirable trees or other plants, on areas where their

CONTROLLING DROPLET SIZE - AIRCRAFT
• Number of Nozzles - Use the minimum number of nozzles
with the highest flow rate that provide uniform coverage.
• Nozzle Orientation - Orienting nozzles so that the spray is
emitted backwards, parallel to the airstream will produce
larger droplets than other orientations.
• Nozzle Type - Solid stream nozzles (such as disc and core
with swirl plate removed) oriented straight back produce
larger droplets than other nozzle types.
• Poor weed and brush control may result from the following:
–Use on poorly drained sites
BOOM LENGTH AND HEIGHT
–Applications made when the soil is saturated with water and
rain is imminent within 24 hours
• Boom Length (aircraft) - The boom length should not
exceed 3/4 of the wing length, using shorter booms decreases
drift potential. For helicopters use a boom length and position
that prevents droplets from entering the rotor vortices.
–Applications to soils high in organic matter (greater
than 5%)
• Following mechanical cutting or clearing, allow stumps and
injured trees sufficient time to adequately resprout before
applying VELPAR L.
• Boom Height (aircraft) - Application more than 10 ft above
the canopy increases the potential for spray drift.
• Do not use VELPAR L on frozen soils.
• Boom Height (ground) Setting the boom at the lowest
labeled height (if specified) which provides uniform coverage
reduces the exposure of droplets to evaporation and wind.
The boom should remain level with the crop and have
minimal bounce.
• Weed and brush control results depend on sufficient moisture
to activate VELPAR L.
• When VELPAR L is applied as a basal soil treatment, there is
no restriction on grazing by domestic animals nor on cutting
surrounding vegetation for forage or hay.
WIND
• For broadcast pasture applications of VELPAR L, do not cut
treated vegetation for forage or hay nor graze domestic
animals on treated areas for 60 days.
Drift potential increases at wind speeds of less than 3 mph
(due to variable direction and inversion potential) or more
than 10 mph. However, many factors, including droplet size
and equipment type determine drift potential at any given
wind speed. AVOID GUSTY OR WINDLESS
CONDITIONS.
SPRAY DRIFT MANAGEMENT
The interaction of many equipment- and weather-related factors
determines the potential for spray drift. The applicator is
responsible for considering all these factors when making
application decisions. Avoiding spray drift is the responsibility
of the applicator.
Note: Local terrain can influence wind patterns. Every
applicator should be familiar with local wind patterns and
how they effect spray drift.
IMPORTANCE OF DROPLET SIZE
TEMPERATURE AND HUMIDITY
The most effective way to reduce drift potential is to apply large
droplets (greater than 150–200 microns). The best drift
management strategy is to apply the largest droplets that provide
sufficient coverage and control. The presence of sensitive
species nearby, the environmental conditions, and pest pressure
may affect how an applicator balances drift control and
coverage. Applying larger droplets reduces drift potential, but
will not prevent drift if applications are made improperly or
under unfavorable environmental conditions! See the Wind,
Temperature and Humidity, and Temperature Inversions sections
below.
When making applications in hot and dry conditions, set up
equipment to produce larger droplets to reduce effects of
evaporation.
SURFACE TEMPERATURE INVERSIONS
Drift potential is high during a surface temperature inversion.
Surface inversions restrict vertical air mixing, which causes
small suspended droplets to remain close to the ground and
move laterally in a concentrated cloud. Surface inversions are
characterized by increasing temperature with altitude and are
common on nights with limited cloud cover and light to no
wind. They begin to form as the sun sets and often continue
into the morning. Their presence can be indicated by ground
fog; however, if fog is not present, inversions can also be
identified by the movement of smoke from a ground source or
an aircraft smoke generator. Smoke that layers and moves
laterally in a concentrated cloud (under low wind conditions)
indicates a surface inversion, while smoke that moves upward
and rapidly dissipates indicates good vertical air mixing.
CONTROLLING DROPLET SIZE
- GENERAL TECHNIQUES
• Volume - Use high flow rate nozzles to apply the highest
practical spray volume. Nozzles with higher rated flows
produce larger droplets.
• Pressure - Use the lower spray pressures recommended for the
nozzle. Higher pressure reduces droplet size and does not
improve canopy penetration. When higher flow rates are
needed, use a higher-capacity nozzle instead of increasing
pressure.
SHIELDED SPRAYERS
• Nozzle Type - Use a nozzle type that is designed for the
intended application. With most nozzle types, narrower spray
angles produce larger droplets. Consider using low-drift
nozzles.
Shielding the boom or individual nozzles can reduce the
effects of wind. However, it is the responsibility of the
applicator to verify that the shields are preventing drift, and
not interfering with uniform deposition of the product.

SPRAY TANK CLEANOUT
LIMITATION OF
Thoroughly clean all traces of VELPAR L from application
equipment immediately after use. Flush the tank, pump,
hoses, and boom with several changes of water after
removing nozzle tips and screens (clean these parts
separately).
