DuPont™ VELPAR® DF herbicide is a water-dispersible
granule that is mixed in water and applied as a spray for
weed control in certain crops, Christmas trees, forestry site
preparation and release areas, and industrial areas. It may
also be applied as a basal soil treatment for brush control in
reforestation areas, rangeland, pastures and noncrop areas.
APPLICATION INFORMATION
VELPAR® DF is an effective general herbicide providing
both contact and residual control of many annual and
biennial weeds and woody plants. It is also effective for
control of most perennial weeds.
VELPAR® DF may be applied by ground equipment and,
where permitted, aerial equipment. Use rates, minimum spray
gallonage, and other application information are described for
various uses.
VELPAR® DF is noncorrosive to equipment.
Dispose of the equipment washwater by applying it to a use-
site listed on this label or in accordance with directions given
in the “Storage and Disposal” section of this label.
Caution should be exercised when applying VELPAR® DF
near desirable trees or shrubs as they can absorb VELPAR®
DF through roots extending in to treated areas.
Before spraying, calibrate equipment to determine the quantity
of water necessary to uniformly and thoroughly cover the
vegetation and soil in a measured area to be treated. Make sure
the volume of water is sufficient to completely suspend the
VELPAR® DF.
This product may be applied on conifer plantations and non-
crop sites that contain areas of temporary surface water
caused by collection of water between planting beds, in
equipment ruts, or in other depressions created by
management activities. It is permissible to treat intermittent
drainage, intermittently flooded low lying sites, seasonally
dry flood plains and transitional areas between upland and
lowland sites 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.
TANK MIXTURES
VELPAR® DF herbicide may be tank mixed with other
herbicides and /or adjuvants registered for the uses (crops)
specified in the label.
Refer to the label of the tank mix partner(s) for any additional
use instructions or restrictions.
RESISTANCE
ENVIRONMENTAL CONDITIONS
AND BIOLOGICAL ACTIVITY
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.
VELPAR® DF is absorbed through the roots and foliage.
Moisture is required to activate VELPAR® DF in the soil.
Best results are obtained when the soil is moist at the time
of application and 1/4–1/2 inches of rainfall occurs within 2
weeks after application.
For best results, apply VELPAR® DF preemergence or
postemergence when weeds are less than 2 inches in height or
diameter. Herbicidal activity is most effective under conditions
of high temperature (above 80 °F), high humidity, and good soil To better manage herbicide resistance through delaying the
moisture. Herbicidal activity may be reduced when vegetation is proliferation and possible dominance of herbicide resistant
dormant, semi-dormant, or under stress(e.g. temperature or
moisture).
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.
Herbicidal activity will usually appear within 2 weeks after
application to susceptible plants under warm, humid conditions;
while 4–6 weeks may be required when weather is cool or dry,
or when susceptible plants are under stress. If rainfall after
application is inadequate to activate VELPAR® DF in the soil,
plants may recover from contact effects and continue to grow.
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.
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
subsequent refoliation may occur, but susceptible plants are
killed.
The degree and duration of control will depend on the following:

MIXING INSTRUCTIONS
1. Fill the supply tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of VELPAR®
DF and continue agitation until the VELPAR® DF is
fully dispersed, at least 5 minutes.
3. Once the VELPAR® DF is fully dispersed, maintain
agitation and continue filling tank with water.
VELPAR® DF should be thoroughly mixed with water
before adding any other material.
4. As the tank is filling, add tank mix partners (if desired).
Follow use precautions and directions on the tank mix
partner label.
5 After thorough mixing, the agitation system can be
stopped to prevent excessive foaming in the tank. Once
thoroughly mixed the solution in the supply tank does not
require additional agitation unless specified on the
companion products label. If foaming occurs in the
injection supply tank, a defoaming agent (defoamer) may
be added.
turers or other experts.
A person knowledgeable of the chemigation system and
responsible for its operation, or under the supervision of the
responsible person, shall shut the system down and make
necessary adjustments should the need arise.
DORMANT APPLICATIONS
Select the appropriate rate (see Use Rates section) for soil
texture and organic matter content using 0.25” to 0.75” of
sprinkler irrigation as a continuous injection during the
application. Best results are obtained when soil is moist at
time of application, and when weeds have not germinated or
are less than 2” tall or across.
6. Apply VELPAR® DF spray mixture within 48 hours of
mixing to avoid product degradation.
APPLICATION AFTER CUTTING
USE PRECAUTIONS - CHEMIGATION
Apply DuPont™ VELPAR® DF at 5.3 ounces per acre to
stubble after cutting, following hay removal, and before
regrowth exceeds 2” in height. Apply VELPAR® DF using
0.25” to 0.75” of sprinkler irrigation as a continuous
injection during the application. Best results are obtained
when soil is moist at time of application and when weeds
have not germinated or are less than 2” tall or across.
NOTE: Making an application when daily temperatures are
forecast to be in the mid-to-high 90 degree range within 3 to
5 days after treatment may increase the potential for crop
injury.
•
Do not connect an irrigation system (including
greenhouse systems) used for pesticide application to a
public water system unless the pesticide label prescribed
safety devices for public water systems are in place.
•
Distributing treated water in an uneven manner can result
in crop injury, lack of effectiveness, or over-tolerance
pesticide residues in the crop. Therefore, to ensure that
the mixture is applied evenly at the recommended rate,
use sufficient water, apply the mixture for the proper
length of time and ensure sprinkler produces a uniform
water pattern.
SPRINKLER CHEMIGATION
•
Do not permit run-off during chemigation.
The system must contain a functional check valve, vacuum
relief valve, and low pressure drain appropriately located on
the irrigation pipeline to prevent water source contamination
from backflow.
The pesticide injection pipeline must contain a functional,
automatic, quick-closing check valve to prevent the flow of
fluid back toward the injection pump.
The pesticide injection pipeline must also contain a
functional, normally closed, solenoid-operated valve located
on the intake side of the injection pump and connected to
the system interlock to prevent fluid from being withdrawn
from the supply tank when the irrigation system is either
automatically or manually shut down.
The system must contain functional interlocking controls to
automatically shut off the pesticide injection pump when the
water pump motor stops.
POSTING OF AREAS TO BE TREATED

• Do not use VELPAR® DF in low desert valleys in
California or Arizona.
USE PRECAUTIONS - ALFALFA
• Best results are obtained when 1/2–1 inches 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 inches in
height or diameter. Heavy rainfall or excessive irrigation
after application may result in crop injury or poor
performance of the herbicide.
• Do not add a surfactant to VELPAR® DF when treating
nondormant alfalfa.
• Do not use VELPAR® DF on gravelly or rocky soils,
exposed subsoils, hardpan, sand, poorly drained soil, or
alkali soils.
• Do not graze or feed forage or hay to livestock within 30
days following application.
•
•
•
On soils high in organic matter (greater than 5%), the
effectiveness of DuPont™ VELPAR® DF can be signifi-
cantly reduced and weed control may be unsatisfactory.
SEED ALFALFA (CALIFORNIA ONLY)
ADDITIONAL USE PRECAUTIONS
• Do not use VELPAR® DF on fields with sandy loam or
loamy sand soils having less than 1% organic matter.
Crop injury, including mortality, may result in fields with
restricted root growth due to non-uniform soil profiles
such as gravel bases and clay lenses.
• Do not exceed 2/3 pound per acre on fields with sandy loam
or loamy sand soils having 1–2% organic matter.
Crop injury may result if hot weather, mid-to-high 90
degree range or higher, occurs within a few days after
application.
• Do not exceed 2/3 pound per acre on seed alfalfa that has
been established for only one growing season.
• Do not apply to snow-covered or frozen ground.
• Since the effect of VELPAR® DF on alfalfa varies with soil
conditions, uniformity of application, and environmental
conditions, growers should limit their first use to small
areas.
BLUEBERRY
HIGH BUSH BLUEBERRIES
VELPAR® DF is recommended for control of certain
herbaceous and woody weeds in established high bush
blueberry fields.
• If abnormally dry conditions exist following application,
restrict the first irrigation to no more than 1/2 acre inch of
water.
APPLICATION INFORMATION
• Temporary yellowing of alfalfa may occur following
VELPAR® DF applications.
VELPAR® DF may be applied to high bush blueberries that
have been established for 3 or more years. Apply
VELPAR® DF in the spring before blueberry leaf
emergence. Direct the spray solution towards the soil and
weeds.
• Treat only stands of alfalfa established for one year or for
one growing season (except in California), provided:
–The alfalfa stand has a well developed tap root structure
that is at least 10 inches in length (0.25 inch diameter
below the crown) throughout the field and the crop is
healthy, vigorous, and not under stress from weather
conditions, low fertility, insects or disease damage.
Using calibrated ground spray equipment, make the
application in sufficient water to provide thorough and
uniform coverage to the treated area (usually 20 gallons per
acre). Shut off spray booms when starting, turning, slowing
or stopping, or injury to the crop may result.
–In areas with shorter growing seasons, such as, higher
elevations, adequate alfalfa tap root growth may not occur
and especially when alfalfa is grown together with a cover
or nurse crop. If an adequate tap root is not present, delay
application of VELPAR® DF until the alfalfa has gone
through a minimum of two growing seasons.
USE PRECAUTIONS
• Do not apply through any type of irrigation system.
• Do not apply within 90 days of harvest.
• Do not apply to flooded field with standing water.
• Application to blueberry foliage will result in crop injury.
• In California, fall planted alfalfa may be treated in the
following winter months with VELPAR® DF at 1/3 to 2/3
pounds per acre (use higher rate for fine textured soils)
provided:
• Since the effect of VELPAR® DF on blueberries varies
with soil type, plant vigor, uniformity of applications and
amount of rainfall, it is suggested that growers limit their
first use to small areas.
- alfalfa root growth exceeds 6 inches in length
- vegetative top growth of alfalfa has lateral development of
secondary growth
LOW BUSH BLUEBERRIES
VELPAR® DF may be used for the control of certain weeds
in low bush blueberries.
- alfalfa is healthy and vigorous, not growing under stress
from insect, disease, winter injury or other types of stress.
Injury may result to alfalfa plants that fail to meet these
growth criterion listed above.
• Do not use VELPAR® DF on seedling alfalfa, alfalfa-grass
mixtures, or other mixed stands as injury may result to the
seedling alfalfa or companion crop.

• Extremely heavy rainfall after application may result in
poor weed control and/or crop injury, especially if the
application is made to dry soil.
In areas where other conifer species may be mixed in with the
conifers listed above, VELPAR® DF may be applied if the user
has prior experience with VELPAR® DF on the other conifer
species. With no prior experience, it is recommended that either
a small area of plantings be tested for conifer safety prior to
treating larger areas, or make no application of VELPAR® DF
in these areas within the site preparation area. Conifer species
that are sensitive to VELPAR® (hexazinone) DF, such as, sugar
pine and western larch, require 18 months before interplanting
on treated sites.

Suppression is a visible reduction in plant competition (reduced
population and/or vigor) as compared to an untreated area. Degree
of suppression will vary with rate applied, size of plants at
application and environmental conditions following treatment.
Species indicated above, especially resprouts of these species, may
require a follow up treatment for acceptable control. Burning, as a
follow up treatment, will enhance control of resprouts.
Within several weeks after VELPAR® DF activation by
rainfall, affected vegetation may be burned, if desired. This
burn may further enhance control of vegetation. Burn the

For multi-stemmed and low-growing brush that have stem
diameters that are difficult to determine, apply the
DuPont™ VELPAR® DF suspension at the rate of 2 to 4 ml
per 3 feet of canopy width. For tall, slender (columnar)
brush types, apply 4 to 8 ml per 3 feet of height. Base the
rate on whichever canopy dimension is greater (width or
height). Apply the lower volumes for coarse textured soils
or soils with low organic matter soils and the higher
volumes for fine textured soils or soils with high organic
matter.
APPLICATION INFORMATION
EASTERN US
Apply VELPAR® DF from early spring to early summer
after hardwoods have broken bud and before full leaf
expansion.
Applications made over the top of pines may result in
excessive pine injury under conditions of high humidity and
temperature (80 degrees F).
WESTERN US
When treating brush that requires more than a single
delivery of the VELPAR® DF suspension, apply subsequent
deliveries equally spaced around the target plant. If treating
brush on sloping sites, apply most of the suspension on the
uphill side of the stem. If treating resprouts from brush
disturbed by cutting or other mechanical methods, the rate
of application should be proportional to the original tree
size, not just the size of sprout regrowth.
Rainbelt (areas of high spring rainfall): For best results,
apply in late winter or spring when brush is actively
growing, but prior to conifer budbreak. If application is
made after bud break, use directional spray equipment to
prevent contact with conifer foliage, as injury may result.
Snowbelt (areas of low spring rainfall): For best results,
apply 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. Brush control results
from spring treatments will be dependent on sufficient
rainfall following application to activate VELPAR® DF.
USE PRECAUTIONS
SITE PREPARATION
Where burning is desired, burn the vegetation only after any
residual brush has completely defoliated, at least twice,
allowing for sufficient root uptake of VELPAR® DF.
USE RATES
The rates listed below are for broadcast application. Do not
use more than one application of VELPAR® DF per year.
Use the higher rate range for the harder to control*
(suppression) species in the PLANTS CONTROLLED
listings of the Site Prep and Release sections.
Following harvest, allow sufficient time for stumps and
injured trees to adequately resprout before applying
VELPAR® DF.

FORESTRY
IMPREGNATION ON DRY BULK
FERTILIZER
DuPont™ VELPAR® DF is recommended for impregnating
or coating dry bulk fertilizer to be applied on forested sites
for the establishment or release of conifer plantations
(except longleaf pine) as specified on this label.
• The dry fertilizer must be properly impregnated and
uniformly applied to avoid pine injury/mortality and poor
weed and brush control.
• Uniform and precise application of the impregnated
fertilizer is essential for satisfactory weed and brush
control and to minimize pine injury. Overlaps or skips
between adjoining swaths or non-uniform distribution of
impregnated fertilizer within the swath will deliver poor
results and may result in pine injury or mortality.
PLANTS CONTROLLED
Fertilizer impregnated with VELPAR® DF is recommended
for the control and suppression of the weeds and brush
identified for the specific applications on this label. Consult
the appropriate segment of this label to determine the
appropriate rate of VELPAR® DF to be applied per acre.
Apply this amount of VELPAR® DF to the volume of
fertilizer to be applied per acre.
• Do not impregnate potassium nitrate, sodium nitrate or
triple super phosphate fertilizers with VELPAR® DF as
herbicidal action will be lost.
USE PRECAUTIONS
FORESTRY
IMPREGNATION EQUIPMENT
• Do not use VELPAR® DF in nurseries, seedbeds, or
ornamental plantings.
To impregnate or coat the fertilizer use a system consisting
of conveyor or closed drum used to blend dry bulk fertilizer.
• On tracts of land where various soil types are present and
VELPAR® DF rate selection is difficult, conifer damage
or less-than-expected vegetation suppression may occur
due to the different rates required for various soil types.
IMPREGNATION INSTRUCTIONS
To impregnate dry bulk fertilizer with VELPAR® DF, mix
the amount as prescribed above in a sufficient quantity of
water to uniformly coat the desired amount of fertilizer.
Suspensions of VELPAR® DF will require thorough
agitation.
• Poor weed and brush control may result from the
following:
–Heavy duff or slash present at time of application
–Use on poorly drained sites
Direct the spray nozzles of the impregnation equipment to
deliver a fine spray of the mixture toward the fertilizer for
thorough coverage while avoiding contact with mixing
equipment. The use of a spray pattern indicator may be
beneficial to visually determine the uniformity of impreg-
nation.
–Applications made when the soil is saturated with water
and rain is imminent within 24 hours
–Applications to soils high in organic matter (greater
than 5%)
Uniform impregnation of dry bulk fertilizer may vary. If
absorption of the spray is not adequate, the use of an
absorptive powder or additive, such as “Microcel E” or
“HiSil 233”, may be required to produce a dry, free flowing
mixture.
• Following harvest, allow stumps and injured trees
sufficient time to adequately resprout before applying
VELPAR® DF.
• Where burning is desired, burn vegetation after any brush
has completely defoliated, at least twice, allowing for
sufficient root uptake of VELPAR® DF.
Apply the fertilizer as soon as possible after impregnation
for optimum performance. Impregnated fertilizer may
become lumpy and difficult to apply following storage.
• Do not use VELPAR® DF on frozen soils; use in spring
after snow melt.
Diammonium phosphate, potassium chloride, 16-16-16 and
24-4-4 have been successfully impregnated.
• Do not add a surfactant in applications over the top of
conifers.
APPLICATION EQUIPMENT
• Weed control results from spring applications depend on
sufficient moisture to activate VELPAR® DF.
Applications of impregnated fertilizer may be made by
ground equipment or by air (helicopter or fixed wing).
Accurate calibration and patterning of the equipment is
essential for uniform distribution of the impregnated
fertilizer on the soil surface.
• When applying VELPAR® DF after transplanting, wait
until rainfall has settled the soil around the base and root
systems of the transplants before making the treatment.
• Crop injury may occur when VELPAR® DF is used:
USE PRECAUTIONS
IMPREGNATED FERTILIZER FOR
FORESTRY
• If fertilizer materials are excessively dusty, use a suitable
additive to reduce dust prior to impregnation. Application
of dusty fertilizer which has been impregnated may result
in off-target drift and injury to desirable vegetation. Such
–On trees that show poor vigor, insect damage, disease,
winter injury, or other stress conditions
–On any soil containing less than 1% organic matter
–On loamy sand or sandy loam with less than 2% organic
matter, except Jeffrey pine and Ponderosa pine
–On conifer foliage after conifer bud break
17
–On gravelly or rocky soils, exposed subsoils, clay knobs,
sand, or sandy soil with 85% or more sand.
APPLICATION INFORMATION
Make a single application of VELPAR® DF per year when
weeds are actively growing.
• Do not cut treated vegetation for forage or hay nor graze
domestic animals on treated areas for 60 days following
application.
WEEDS CONTROLLED - USE RATES
VELPAR® DF effectively controls the following weeds at the
rates shown in pastures. Use a lower rate on coarse-textured
soils (sand to sandy loam). Use the higher rate on fine-textured
soils (clay loam to clay) and on soils high in organic matter.
YELLOW POPLAR PLANTINGS
DuPont™ VELPAR® DF is recommended for the control of
herbaceous weeds in the establishment of yellow poplar
plantations. Applications may be made over the top of
planted seedlings after the soil has settled around the root
systems but before the seedlings have broken dormancy
(bud break). A subsequent application may be made before
dormancy break in the Spring of the second year. USE

VELPAR® DF and DuPont™ ESCORT® XP made to
yellow poplar seedlings that are suffering from loss of
vigor caused by insects, disease, drought, winter damage,
animal damage, excessive soil moisture, planting shock
or other stresses may injure or kill the seedlings.
USE PRECAUTIONS - PASTURE
• Use VELPAR® DF only in stands of bermudagrass and
bahiagrass established for at least one year. Do not treat
newly sprigged or sodded areas.
• Some temporary discoloration of the bermudagrass or
bahiagrass may occur after application.
• Applications of VELPAR® DF and tank mixes of
VELPAR® DF and ESCORT® XP should only be made
after adequate rainfall has closed the planting slit and
settled the soil around the roots following transplanting.
• Treatment of mixed pastures containing forage species
other than bermudagrass or bahiagrass may result in
injury or mortality to the other forage species.
• The use of surfactant with VELPAR® DF is not
recommended for applications made over the tops of
seedlings.
• Injury may result when desirable grasses are under stress
from drought, insects, disease, cold temperature, or poor
fertility.
• Careful consideration must be given by an experienced
and knowledgeable forester to ensure the specific growth
requirements of yellow poplar will be provided by the
selected planting site. Treatment of yellow poplar
planted on a site inadequate to meet its requirements may
injure or kill the seedlings.
• Injury to or loss of desirable trees or other plants may
result if VELPAR® DF is applied or if equipment is
drained or flushed on or near desirable trees or other
plants, on areas where their roots may extend, or in
locations where the chemical may be washed or moved
into contact with their roots.
• Severe crop injury may occur if applications are made on
gravelly or rocky soils, thinly covered subsoils, or soils
with less than 1% organic matter.
PASTURE / RANGELAND
VELPAR® DF is recommended for control of brush and

SPECIFIC WEED PROBLEMS
USE PRECAUTIONS
INDUSTRIAL UNIMPROVED TURF
• Use VELPAR® DF only in stands of bermudagrass and
bahiagrass established for at least one year. Do not treat newly
sprigged or sodded areas.
Control of Canada Thistle in Crown Vetch - DuPont™
VELPAR® DF is recommended for control of Canada thistle in
established stands of crown vetch on noncrop sites. Make a
single application of 1 - 1 2/3 lb of VELPAR® DF from late
spring through mid-summer, when thistle is actively growing
prior to flowering. Do not use a surfactant. Some discoloration
of the crown vetch foliage may occur after application.
• 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.
SPRAY EQUIPMENT
• 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.
Apply VELPAR® DF uniformly over the desired area using
ground equipment or helicopter. Do not apply more than 8 lbs
per acre by air.
NON-CROP
BRUSH CONTROL
VELPAR® DF is recommended for the control of
undesirable brush in non-crop sites.
Use enough water for thorough coverage. For ground
application this is usually a minimum of 25 gallons per acre.
Higher application volumes may be needed to obtain uniform
application with handgun equipment. For aerial applications
(helicopter only) this is usually a minimum of 5 gallons per
acre. Higher volumes of water may be needed when water
temperatures are cold or the higher rates of VELPAR DF are
used.
APPLICATION INFORMATION
Apply VELPAR® DF from late winter through summer,
prebud break until new growth hardens off.
INDUSTRIAL TURF
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.
(UNIMPROVED ONLY)
VELPAR® DF is recommended for selective weed control in
established stands of bermudagrass and/or bahiagrass in noncrop
areas.
BROADCAST
Apply 5 1/3 to 10 2/3 lb of VELPAR® DF per acre as a
coarse spray by ground equipment or 5 1/3 to 8 lb per acre by
air (helicopter only). Use enough water for thorough
coverage. For ground equipment, usually a minimum of 25
gallons per acre. For aerial equipment, usually a minimum of
10 gallons per acre. Higher volumes of water may be needed
when water temperatures are cold or the higher rates of
VELPAR® DF are used.
APPLICATION TIMING
Make a single application of VELPAR® DF per year when
weeds are actively growing.
WEEDS CONTROLLED - USE RATE
VELPAR® DF effectively controls the following weeds at the
rates shown in industrial turf (unimproved only). Use a lower
rate on coarse-textured soils (sand to sandy loam). Use the
higher rate on fine-textured soils (clay loam to clay) and on soils
high in organic matter.
BASAL (SOIL)
SINGLE STEM TREATMENT
9/10 - 1 1/2 Lb/Acre
Mix 2 2/3 pounds of VELPAR® DF with sufficient water to
make one gallon of suspension and thoroughly agitate. Apply
the VELPAR® DF suspension with an exact-delivery
handgun applicator. This equipment delivers a thin stream of
predetermined volume when triggered. Apply the VELPAR®
DF suspension at the rate of 2 to 4 ml for each inch of stem
diameter at breast height.

* Suppression may result with some of the giant (larger) smutgrass
species.
For multi-stemmed and low-growing brush that have stem
diameters that are difficult to determine, apply the VELPAR®
DF suspension at the rate of 2 to 4 ml per 3 feet of canopy
width. For tall, slender (columnar) brush types, apply 4 to 8
ml per 3 feet of height. Base the rate on whichever canopy
dimension is greater (width or height).
Suppression – a visible reduction in plant population and/or plant vigor
as compared to an untreated area and generally not accepted as control.
SPRAY EQUIPMENT
Apply VELPAR® DF uniformly over the desired area using
ground equipment only.
For ground application, use enough water for thorough
coverage usually a minimum of 25 gallons per acre. The use
of a surfactant is not recommended.
21
*Suppression – a visible reduction in plant population and/or plant vigor
as compared to an untreated area and generally not accepted as control.
When treating brush that requires more than a single delivery
of the DuPont™ VELPAR® DF suspension, apply subsequent
deliveries equally spaced around the target plant. If treating
brush on sloping sites, apply most of the suspension on the
uphill side of the stem. If treating resprouts from brush
disturbed by cutting or other mechanical methods, the rate of
application should be proportional to the original tree size, not
just the size of sprout regrowth.
USE PRECAUTIONS
NON-CROP
• Injury to or loss of desirable trees or other plants may result if
VELPAR® DF is applied or if equipment is drained or
flushed on or near desirable trees or other plants, on areas
where their roots may extend, or in locations where the
chemical may be washed or moved into contact with their
roots.
LACING/STREAKING - Mix VELPAR® DF with water to
form a concentrated suspension. Apply 5 1/3 to 10 2/3 lbs of
VELPAR® DF per acre. Adjust the application equipment to
deliver a narrow or straight stream spray pattern such that the
swath width on the soil surface is 6 to 12 inches wide. Direct
the spray at the base of the brush. Swaths or treated bands
should be 2 to 4 feet apart. Apply the lower volumes for
coarse textured soils or soils with low organic matter and the
higher volumes for fine textured soils or soils with high
organic matter.
• Application spray drift may injure desirable plants.
• Poor weed and brush control may result from the following:
–Use on poorly drained sites
–Applications made when the soil is saturated with water and
rain is imminent within 24 hours.
–Applications to soils high in organic matter (greater
than 5%).
USE RATES
• Following mechanical cutting or clearing, allow stumps and
injured trees sufficient time to adequately resprout before
applying VELPAR® DF.
VELPAR® DF is recommended for the control or
suppression of the following species in non-crop sites. Use
lower rate on coarse-textured soils (sand to sandy loam).
Use the higher rate on fine-textured soils(clay loam to clay)
and on soils high in organic matter.
• Do not use VELPAR® DF on frozen soils.
• Do not use VELPAR® DF on lawns, driveways, tennis courts,
or other residential or recreational areas.
5 1/3 to 10 2/3 Lb/Acre

IMPORTANCE OF DROPLET SIZE
Prosopis glandulosa
Morus spp
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,

CONTROLLING DROPLET SIZE
- GENERAL TECHNIQUES
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.
• 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.
• 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.
CONTROLLING DROPLET SIZE - AIRCRAFT
SHIELDED SPRAYERS
• Number of Nozzles - Use the minimum number of
nozzles with the highest flow rate that provide uniform
coverage.
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.
• Nozzle Orientation - Orienting nozzles so that the spray is
emitted backwards, parallel to the airstream will produce
larger droplets than other orientations.
SPRAY TANK CLEAN OUT
Thoroughly clean all traces of DuPont™ VELPAR® DF
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). Dispose of the equipment wash water by
applying it to a use-site listed on this label.
• Nozzle Type - Solid stream nozzles (such as disc and core
with swirl plate removed) oriented straight back produce
larger droplets than other nozzle types.
BOOM LENGTH AND HEIGHT
• 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.
• Boom Height (aircraft) - Application more than 10 feet
above the canopy increases the potential for spray drift.
• 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.
WIND
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.
Note: Local terrain can influence wind patterns. Every
applicator should be familiar with local wind patterns and how
they effect spray drift.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, set up
equipment to produce larger droplets to reduce effects of
evaporation.
