GENERAL INFORMATION
DuPont™ VELPAR® L herbicide is a water-dispersible
liquid 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 undiluted as a basal soil treatment for brush
control in reforestation areas, rangeland, pastures and
noncrop areas, or by stem injection for brush control.
VELPAR® L is an effective general herbicide providing
both contact and residual control of many annual, biennial
and perennial weeds and woody plants.
VELPAR® L is noncorrosive to equipment.
Care should be exercised when applying VELPAR® L near
desirable trees or shrubs as they can absorb
VELPAR® L through roots extending into treated areas.

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.
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.

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.

TANK MIXTURES
VELPAR® L 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.
NOTE: When the air temperature is around 32oF, tank
mixtures of “Gramoxone Max” (paraquat dichloride) plus
VELPAR® L may form a hard sludge in the spray tank.
This effect is most likely to occur when the tank mixture
comes into contact with aluminum.

ENVIRONMENTAL CONDITIONS
AND BIOLOGICAL ACTIVITY

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.

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 inches of rainfall occurs within 2
weeks after application.
For best results, apply VELPAR® L preemergence or
postemergence when weeds are less than 2 inches 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.
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.

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.

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

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® L
and continue agitation.
3. Once the VELPAR® L is fully dispersed, maintain
agitation and continue filling tank with water.
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.
6. Apply VELPAR® L spray mixture within 48 hours of
mixing to avoid product degradation.

Apply this product only through center pivot sprinkler
irrigation systems. Do not apply this product through any
other type of irrigation system.
Crop injury, lack of effectiveness, or illegal pesticide
residues in the crop can result from nonuniform distribution
of treated water.
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 Rate 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® L at 1 pint per acre to stubble after
cutting, following hay removal, and before regrowth
exceeds 2” in height. Apply VELPAR® L 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 temperature
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
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.
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

USE PRECAUTIONS
CHEMIGATION
• 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.
• Do not permit run-off during chemigation.
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
such as residential areas, labor camps, businesses, daycare
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
chemigated area is open to the public such as golf courses or
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

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

Posting required for chemigation does not replace other
posting and reentry requirements for farm worker safety.

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
any desired crop. The results of this bioassay may require the
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.
In areas where irrigation is needed to produce the crop, the
crop rotation intervals listed may need to be extended if the
normal irrigation amount is reduced for any reason.

REPLANTING (FOLLOWING ALFALFA)

ALFALFA - IMPREGNATION ON
DRY BULK FERTILIZER (EXCEPT
CALIFORNIA AND ARIZONA)

• 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 3 pints per acre.

Dry bulk fertilizer may be impregnated or coated with
VELPAR® L for application to established alfalfa. All
recommendations and precautions 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.

• Root crops such as potatoes, sugarbeets, radish and carrots
may be planted 12 months after last treatment, provided the
use rate does not exceed 2 pints per acre. Sites with use
rates higher than 2 pints per acre should not be replanted to
any root crop within 2 years after application of DuPont™
VELPAR® L, or unacceptable crop injury may result.
In areas where irrigation is needed to produce the crop, the
crop rotation intervals listed may need to be extended if the
normal irrigation amount is reduced for any reason.

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.
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® L, direct the nozzles to deliver
a fine spray of this suspension toward 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” is the recommended
absorbent powder. When another herbicide is used with
VELPAR® L, mix and impregnate the fertilizer immediately.
Apply impregnated fertilizer as soon as possible after impregnation for optimum performance.
Select the rate of VELPAR® L to apply per acre from the
appropriate section of this label. Then refer to the rate chart
below to determine the amount of VELPAR® L that should be
impregnated on a ton of dry bulk fertilizer, based on the
amount of fertilizer to be distributed in one acre.

• Sugarcane may be planted any time following treatment.
• In California, do not replant seed alfalfa areas to any crop
within two years after treatment, as crop injury may result.

APPLICATION
Uniform application of VELPAR® L-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.

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.
• Do not add a surfactant to VELPAR® L when treating nondormant alfalfa.

USE PRECAUTIONS - ALFALFA

• 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 inch 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.

SEED ALFALFA (CALIFORNIA ONLY)
ADDITIONAL USE PRECAUTIONS
• Do not use VELPAR® L on fields with sandy loam or
loamy sand soils having less than 1% organic matter.
• Do not exceed 2 pints per acre on fields with sandy loam or
loamy sand soils having 1–2% organic matter.

• On soils high in organic matter (greater than 5%), the
effectiveness of VELPAR® L can be significantly reduced
and weed control may be unsatisfactory.

• Do not exceed 2 pints per acre on seed alfalfa that has been
established for only one growing season.

• Crop injury, including mortality, may result in fields with
restricted root growth due to nonuniform soil profiles
such as gravel bases and clay lenses.

BLUEBERRY

• Crop injury may result if hot weather, mid-to-high 90
degree range or higher, occurs within a few days after
application.

HIGH BUSH BLUEBERRIES
VELPAR® L is recommended for control of certain
herbaceous and woody weeds in established high bush
blueberry fields.
APPLICATION INFORMATION
VELPAR® L may be applied to high bush blueberries that
have been established for 3 or more years. Apply
VELPAR® L in the spring before blueberry leaf emergence.
Direct the spray solution towards the soil and weeds.
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.

• Do not apply to snow-covered or frozen ground.
• 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.
• If abnormally dry conditions exist following application,
restrict the first irrigation to no more than 1/2 acre inch of
water.
• 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 alfalfa stand has a well developed tap root structure
that is at least 10 inches in length (0.25 inch diameter

In areas where other conifer species may be mixed in with the
conifers listed above, VELPAR® L may be applied if the user
has prior experience with VELPAR® L 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® L in
these areas within the site preparation area. Conifer species that
are sensitive to VELPAR® (hexazinone) L, 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® L activation by rainfall,
affected vegetation may be burned, if desired. This burn may
further enhance control of vegetation. Burn the vegetation
only after any residual stand is completely defoliated, at least

cutting or shredding, the rate of application should be
proportional to the original tree size, not just the small
regrowth of sprouts.

VELPAR® L. In the West, results may take one to two years
in areas of low rainfall.

SPRAY EQUIPMENT

INJECTION

When applied as a liquid spray using water as the carrier,
VELPAR® L may be applied by ground equipment or by air
(helicopter only).

No Worker Protection Standard worker entry
restrictions or worker notification requirements apply
when this product is directly injected into agricultural
plants.

For ground application, use enough water for thorough
coverage, usually a minimum of 25 gallons per acre. For
aerial applications, use at least 5 gallons of water per acre and
at least 5 gallons of water for every 1 gallon of VELPAR® L.

Inject 1 ml of undiluted VELPAR® L through the bark of
undesirable trees. Injections should be made at 4 inch
intervals around the circumference of the tree. When using
tubular injection equipment, inject near the ground level.
When using the “Hypo-Hatchet” Tree Injector or a similar
devise, inject at waist height. Treatment should be made in
the summer. Woody species controlled include black cherry,
oaks, and sweetgum.

GRID APPLICATION
Apply undiluted VELPAR® L directly to the soil surface in
a grid pattern using an exact delivery handgun applicator.
This equipment delivers a thin stream of a predetermined
volume. VELPAR® L should be applied during the period
from hardwood bud break to early summer.

USE PRECAUTIONS
SITE PREPARATION

Selection of the rate per acre and grid pattern will depend on
soil texture and woody plant composition. Use the lower
rates on coarse textured soils and when the major
component of the hardwoods are susceptible species. Use
the high rates on fine-textured soils and where weeds
identified in the label as “partial control or suppression”
predominate.

BASAL (SOIL)
SINGLE STEM TREATMENT
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 feet 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.
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 feet of canopy width. For tall,
slender (columnar) brush types, apply 4–8 ml per 3 feet of
height. Base the rate on whichever canopy dimension is
greater (width or height).
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

APPLICATION INFORMATION
EASTERN US
Apply DuPont™ VELPAR® L 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
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® L.

For first year plantings using bare root stock, treat only
transplant stock that is 2 years old (2-0, 1-1) or more, except
(1-0) for Ponderosa and Jeffrey pines. Apply VELPAR® L
only if rainfall has settled the soil around the base and root
systems of the transplants.

APPLICATION TIMING

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 feet 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.
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 feet of canopy width. For tall, slender
(columnar) brush types, apply 4–8 ml per 3 feet of height. Base
rate on whichever canopy dimension is greater (width or height).
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.

EASTERN US
Apply VELPAR® L as a broadcast or banded spray in the spring
prior to conifer bud break to lessen conifer injury potential.
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.
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.

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-foot band where row spacing
is 6 feet.

INJECTION
No Worker Protection Standard worker entry restrictions or
worker notification requirements apply when this product is
directly injected into agricultural plants.
Inject 1 ml of undiluted VELPAR® L through the bark of

• 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
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.

* Suppression – a visible reduction in plant population and/or plant
vigor as compared to an untreated area and generally not accepted
as 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 nonuniform distribution of
impregnated fertilizer within the swath will deliver poor
results and may result in pine injury or mortality.

BULK FERTILIZER
VELPAR® L 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.
PLANTS CONTROLLED
Fertilizer impregnated with VELPAR® L is recommended
for the control and suppression of the weeds and brush
identified for the specific applications on this label. Consult

• Do not impregnate potassium nitrate, sodium nitrate or
triple super phosphate fertilizers with VELPAR® L as
herbicidal action will be lost.

USE PRECAUTIONS
FORESTRY

Apply 4 to 6 pints per acre of VELPAR® L as
recommended on the package label for "RELEASE—
HERBACEOUS WEED CONTROL" in pine plantations in
the eastern U.S. Follow the label recommendations
regarding varying the application rate by soil texture.

• Do not use DuPont™ VELPAR® L in nurseries, seedbeds, or
ornamental plantings.
• 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.

For ground application, use enough water for thorough
coverage, usually a minimum of 25 gallons per acre. For
aerial applications, use at least 5 gallons of water per acre
and at least 5 gallons of water for every 1 gallon of
VELPAR® L.

• 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%).

For broader spectrum control VELPAR® L may be tank
mixed with DuPont™ ESCORT® herbicide. Add
ESCORT® at a rate of 1/2 ounce per acre to a tank mix with
the prescribed rate of VELPAR® L.

USE PRECAUTIONS
YELLOW POPLAR PLANTINGS

• Following harvest, allow stumps and injured trees sufficient
time to adequately resprout before applying VELPAR® L.

• Applications of VELPAR® L and tank mixes of
VELPAR® L and ESCORT® 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.

• Where burning is desired, burn vegetation only after any
brush has completely defoliated, at least twice, allowing for
sufficient root uptake of VELPAR® L
• Do not use VELPAR® L on frozen soils; use in spring after
snow melt.

• Applications of VELPAR® L and tank mixes of
VELPAR® L and ESCORT® should only be made after
adequate rainfall has closed the planting slit and settled
the soil around the roots following transplanting.

• Do not add a surfactant in applications over the top of
conifers.
• Weed control results from spring applications depend on
sufficient moisture to activate VELPAR® L.

• The use of surfactant with VELPAR® L is not
recommended for applications made over the tops of
seedlings.

• When applying VELPAR® L after transplanting, wait until
rainfall has settled the soil around the base and root systems
of the transplants before making the treatment.

• 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.

• Crop injury may occur when VELPAR® L is used:
–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

• Refer to package labels for information regarding spray
drift management.

YELLOW POPLAR PLANTINGS

APPLICATION INFORMATION

VELPAR® L 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.

Make a single application of VELPAR® L per year when weeds
are actively growing.
WEEDS CONTROLLED - USE RATES
VELPAR® L effectively controls the following weeds at the
rates shown. Use a lower rate on coarse-textured soils (sand to

BASAL (SOIL)
Undiluted - Apply VELPAR® L undiluted with an exactdelivery handgun applicator. This equipment delivers a thin
stream of a predetermined volume when triggered. Apply
VELPAR® L at the rate of 2 to 4 ml for each inch of stem
diameter at breast height. Do not exceed 4 gallons of
VELPAR® L per acre per year. Direct the treatment to the soil
within 3 feet 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.
For multi-stemmed and low-growing brush that have stem
diameters that are difficult to determine, apply VELPAR® L
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).
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.
Diluted - Mix one gallon of VELPAR® L with 5 or more
gallons of water. Apply 2 to 4 gallons of VELPAR® L per
acre. Direct the spray to the soil in a serpentine pattern so that
the swath on the soil is 6 to 12 inches wide at the base of the
brush. Swaths should be 2 to 4 feet apart.

USE PRECAUTIONS
NON-CROP
• 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
roots may extend, or in locations where the chemical may be
washed or moved into contact with their roots.
• 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%).
22

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

• Following mechanical cutting or clearing, allow stumps and
injured trees sufficient time to adequately resprout before
applying VELPAR® L.
• Do not use VELPAR® L on frozen soils.
• Do not use DuPont™ VELPAR® L on lawns, driveways,
tennis courts, or other residential or recreational areas.
• Weed and brush control results from spring applications
depend on sufficient moisture to activate VELPAR® L.
• Do not cut treated vegetation for forage or hay nor graze
domestic animals on treated areas for 60 days following
application. For rates above 3 gallons per acre, do not cut
treated vegetation for forage or hay nor graze domestic
animals for 1 year.

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.

ADDITIONAL USE INFORMATION
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.

TEMPERATURE AND HUMIDITY

IMPORTANCE OF DROPLET SIZE
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.
• 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.

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.
SENSITIVE AREAS
The pesticide should only be applied when the potential for
drift to adjacent sensitive areas (e.g., residential areas,
bodies of water, known habitat for threatened or endangered
species, non-target crops) is minimal (e.g, when wind is
blowing away from the sensitive areas).

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.
