GENERAL INFORMATION
DuPont™ VELPAR® DF herbicide is a water-dispersible
ranule that is mixed in water and applied as a spray for
g
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.
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 is noncorrosive to equipment.
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.
This product may be applied on conifer plantations and noncrop 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.
• Weed spectrum and size at time of application

•
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
ower levels of the dosage range on coarse-textured soils and/or
l
on soils low in organic matter. Refer to specific uses for rate
ranges.
APPLICATION INFORMATION
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.
Dispose of the equipment washwater by applying it to a usesite listed on this label or in accordance with directions given
in the “Storage and Disposal” section of this label.
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.
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.
ENVIRONMENTAL CONDITIONS
AND BIOLOGICAL ACTIVITY
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
ture (above 80 °F), high humidity, and good soil
of high temper
moisture
dormant, semi-dormant, or under stress(e.g. temperature or
moisture).
Herbicidal activity will usually appear within 2 weeks after
application to susceptible plants under warm, humid conditions;
hile 4–6 weeks may be required when weather is cool or dry,
w
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.
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:

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.

Severe alfalfa injury may result following application after
cutting if either the regrowth is more than 2” high or
significant stubble is left after alfalfa cutting.
If you have questions about calibration, you should contact
State Extension Service specialists, equipment manufacturers 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.
APPLICATION AFTER CUTTING
Apply 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.
SPRINKLER CHEMIGATION
The system must contain a functional check valve, vacuum
elief valve, and low pressure drain appropriately located on
r
the irrigation pipeline to prevent water source contamination
rom backflow.
f
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.
The irrigation line or water pump must include a functional
pressure switch which will stop the water pump motor when
the water pressure decreases to the point where pesticide
distribution is adversely affected.
Systems must use a metering pump, such as a positive
displacement injection pump (e.g., diaphragm pump)
effectively designed and constructed of materials that are
compatible with pesticides and capable of being fitted with
a system interlock.
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.
After thorough mixing, the agitation system can be
5
stopped to prevent excessive foaming in the tank. Once
thoroughly mixed the solution in the supply tank does not
equire additional agitation unless specified on the

POSTING OF AREAS TO BE TREATED
Posting of areas to be chemigated is required when 1) any
part of a treated area is within 300 feet of sensitive areas
uch as residential areas, labor camps, businesses, daycare
s
centers, hospitals, in-patient clinics, nursing homes, or any
public areas such as schools, parks, playgrounds, or other
public facilities not including public roads, or 2) when the
hemigated area is open to the public such as golf courses or
c
retail greenhouses.
Posting must conform to all the following requirements:
• Treated areas shall be posted with signs at all usual points
of entry and along likely routes of approach from the
listed sensitive areas. When there are no usual points of
entry, signs must be posted in the corners of the treated
areas and in any other location affording maximum
visibility to sensitive areas.
• The printed side of the sign should face away from the
treated area towards the sensitive area. The signs shall be
printed in English. Signs must be posted prior to
application and must remain posted until foliage has dried
and soil surface water has disappeared. Signs may remain
in place indefinitely as long as they are composed of
materials to prevent deterioration and maintain legibility
for the duration of the posting period.
• All words shall consist of letters at least 2 1/2 inches tall,
and all letters and the symbol shall be a color which
sharply contrasts with their immediate background. At
the top of the sign shall be the words “KEEP OUT”,
followed by an octagonal stop sign symbol at least 8
inches in diameter containing the word “STOP”. Below
the symbol shall be the words “PESTICIDE IN
IRRIGATION WATER”.
• Posting required for chemigation does not replace other
posting and reentry requirements for farm worker safety.
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.
• Corn may be planted 12 months after the last treatment in
areas of moderate to high rainfall (greater than 20 inches),
provided the use rate did not exceed 1 lb per acre.
• Root crops such as potatoes, sugarbeets, radish and carrots
may be planted 12 months after last treatment, provided the
te does not exceed 2/3 lb per acre. Sites with use

FLOOD IRRIGATED ALFALFA
In arid climates (10 inches of rainfall or less per year) or areas
where drought conditions have prevailed for one or more
years, a field bioassay should be completed prior to planting
ny desired crop. The results of this bioassay may require the
a
rotation intervals listed above to be extended.
A successful bioassay means growing to maturity a test strip
of the crop(s) intended for production. The test crop(s) strip
should cross the entire field including knolls, low areas, and
areas where any berms were located.
ALFALFA - IMPREGNATION ON
DRY BULK FERTILIZER (EXCEPT
CALIFORNIA AND ARIZONA)
Dry bulk fertilizer may be impregnated or coated with
VELPAR® DF for application to established alfalfa. All
recommendations on this label must be followed along with
state regulations relating to dry bulk fertilizer blending, impregnating and labeling.
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.
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®
DF, except potassium nitrate or sodium nitrate. Do not use
VELPAR® DF on limestone.
Use a minimum of 250 lb dry bulk fertilizer per acre and up to
a maximum of 450 lb per acre. To impregnate or coat the dry
bulk fertilizer with VELPAR® DF, mix 2 2/3 pounds of
VELPAR® DF with sufficient water to make one gallon of
suspension and thoroughly agitate. Direct the nozzles to
deliver a fine spray of this suspension toward the fertilizer for
thorough coverage while avoiding spray contact with mixing

APPLICATION
Uniform application of VELPAR® DF-impregnated dry
fertilizer is essential for satisfactory weed control. Accurate
calibration of the application equipment is essential for
uniform distribution to the surface. The recommended
method of application is to apply 1/2 the recommended rate
and overlap 50%. This results in the best distribution
pattern.
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

PUERTO RICO
For preemergence treatments, apply 1/3 - 2/3 pound of
VELPAR® DF per acre.
For postemergence treatments, apply 1/3 - 2/3 pound of
VELPAR® DF per acre to weeds after they have emerged. Use
the lower rates on coarse-textured soils and the higher rates on
fine-textured soils (high in clay or organic matter). Each ratoon
may receive up to 2/3 pound of VELPAR® DF per acre.
For spot treatment of emerged weeds, VELPAR® DF may be
applied with a knapsack sprayer in concentrations of 1/3 - 2/3
pound per 100 gallons of water. Apply a sufficient volume to
wet the weed foliage. Do not exceed 100 gallons of spray per
treated acre. Use the lower concentration on coarse-textured
soils and the higher concentration on fine-textured soils.
Note: Since it is difficult to calibrate “spot” knapsack
applications, extra care must be taken not to exceed the rate
equivalent of the maximum of 2/3 pound VELPAR® DF per
acre.
Do not apply more than 1 1/3 pound of VELPAR® DF per acre
per crop season.
TEXAS
Apply 2/3 - 2 1/3 pound of VELPAR® DF per acre. On plant

The rates listed are for broadcast application. Use the lower rates on
se textured soils and soils low in organic matter. Use the higher
coar
rates on fine textured soils and soils high in organic matter. Use the
higher rates where weeds identified with an * in the Weeds

WESTERN US
For SITE PREPARATION, VELPAR® DF may be applied
at 1.3 to 4 pounds per acre. Use the lower rates on coarse
textured soils and soils low in organic matter. Use the higher
rates on fine textured soils and soils high in organic matter.
Use the higher rates where weeds identified in this label as
“suppression” predominate.
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.
Applications made to shelter wood sites may also result in
mortality to over-story conifers. Factors that may influence
conifer sensitivity in these sites could include application rate,
conifer species, soil characteristics, uniformity of spray distribution across the treatment swath and environmental stress.

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

IMPREGNATION ON DRY BULK
FERTILIZER
ELPAR® DF is recommended for impregnating or coating
V
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.
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.
IMPREGNATION EQUIPMENT
To impregnate or coat the fertilizer use a system consisting
of conveyor or closed drum used to blend dry bulk fertilizer.
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.
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 impregnation.
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.

USE PRECAUTIONS
IMPREGNATED FERTILIZER FOR
FORESTRY
• If fertilizer materials are excessively dusty, use a suitable
educe dust prior to impregnation. Application
e to r
v
diti
ad
of dusty fertilizer which has been impregnated may result
in off-target drift and injury to desirable vegetation. Such
17
drift and associated injury may be aggravated by high
wind conditions.
• 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
ertilizer is essential for satisfactory weed and brush
f
ontrol and to minimize pine injury. Overlaps or skips
c
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.
• Do not impregnate potassium nitrate, sodium nitrate or
triple super phosphate fertilizers with DuPont™
VELPAR® DF as herbicidal action will be lost.
USE PRECAUTIONS
FORESTRY
• Do not use VELPAR® DF in nurseries, seedbeds, or
ornamental plantings.
• 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.
• 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
–Applications to soils high in organic matter (greater
than 5%)

ADDITIONAL USE INFORMATION
SPRAY DRIFT MANAGEMENT
The interaction of many equipment- and weather-related factors
determines the potential for spray drift. The applicator is
esponsible for consider
r
application decisions. Avoiding spray drift is the responsibility
pplicator.
of the a
IMPOR
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.
TANCE OF DROPLET SIZE
ing all these f
actors when making
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
ozzle. Higher pressure reduces droplet size and does not
n
mprove canopy penetration. When higher flow rates are
i
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
• 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.
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

SURFACE TEMPERATURE INVERSIONS
rift potential is high during a surface temperature inversion.
D
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.
SHIELDED SPRAYERS
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 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
