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.  
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.  
VELPAR® L is an effective general herbicide providing  
both contact and residual control of many annual, biennial  
and perennial weeds and woody plants.  
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.  
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.  
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 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® 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.  
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.  
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.  
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 refoliation  
may occur, but susceptible plants are killed.  
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

CHEMIGATION  
ALFALFA  
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 manufac-  
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.  
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.  
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.  
6. Apply VELPAR® L spray mixture within 48 hours of  
mixing to avoid product degradation.  
USE PRECAUTIONS  
CHEMIGATION  
Do not connect an irrigation system (including  
APPLICATION AFTER CUTTING  
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.  
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.  
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  
SPRINKLER CHEMIGATION  
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.  
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 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  
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  
5
 
indefinitely as long as they are composed of materials to  
prevent deterioration and maintain legibility for the  
duration of the posting period.  
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  
any desired crop. The results of this bioassay may require the  
rotation intervals listed above to be extended.  
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”.  
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.  
Posting required for chemigation does not replace other  
posting and reentry requirements for farm worker safety.  
REPLANTING (FOLLOWING ALFALFA)  
ALFALFA - IMPREGNATION ON  
DRY BULK FERTILIZER (EXCEPT  
CALIFORNIA AND ARIZONA)  
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.  
• 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.  
• 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.  
If fertilizer materials are excessively dusty, use a suitable  
additive to reduce dust prior to impregnation, as dusty fertilizer  
will result in poor distribution during application. The dry  
fertilizer must be properly impregnated and uniformly applied to  
the alfalfa to avoid crop injury and/or poor weed control.  
In 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.  
• 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.  
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 impreg-  
nation 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.

- alfalfa is healthy and vigorous, not growing under stress  
from insect, disease, winter injury or other types of stress.  
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 non-  
dormant 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.  
• 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.  
APPLICATION INFORMATION  
VELPAR® L may be applied to high bush blueberries that  
have been established for 3 or more years. Apply  
• If abnormally dry conditions exist following application,  
restrict the first irrigation to no more than 1/2 acre inch of  
water.  
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.  
• 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

pints per 100 gallons of water as a spot treatment.  
• Do not cut treated vegetation for forage or hay nor graze  
domestic animals on treated areas for 60 days following  
application.  
• Poor weed and brush control may result from the following:  
–Heavy duff or slash present at the time of application.  
–Use on poorly drained sites.  
Treatments to field edges and roadsides - Apply VELPAR®

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  
13  
 
twice, allowing for sufficient root uptake of DuPont™  
VELPAR® L. In the West, results may take one to two years  
in areas of low rainfall.  
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.  
SPRAY EQUIPMENT  
When applied as a liquid spray using water as the carrier,  
VELPAR® L may be applied by ground equipment or by air  
(helicopter only).  
INJECTION  
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  
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® L.  
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.  
Following harvest, allow sufficient time for stumps and  
injured trees to adequately resprout before applying  
VELPAR® L.

hardwood bud break to early summer.  
RELEASE UNDILUTED APPLICATIONS  
• Application of VELPAR® L spots closer than 36 inches to  
conifer seedlings in their first season or directly up slope from  
these seedlings may result in injury or mortality.  
Selection of the rate per acre and grid pattern depends 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 this label as “partial  
control or suppression” predominate.  
• Use VELPAR® L on seedlings in their first or fourth year and  
older. Injury may result from use on two and three year old  
seedlings where root growth is extensive but hardiness is  
lacking.

IMPREGNATION INSTRUCTIONS  
VELPAR® L may be used undiluted or mixed with a  
sufficient quantity of water to ensure thorough coverage of  
the fertilizer.  
Red pine only - Refer to recommended rates in the  
APPLICATION INFORMATION - Eastern US table  
on page 13.  
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 colorant or dye may be beneficial  
to visually determine the uniformity of impregnation.  
WESTERN US  
Refer to recommended rates in the APPLICATION  
INFORMATION - Western US table on page 13.  
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.

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.  
FORESTRY—IMPREGNATION ON DRY  
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.  
Do not impregnate potassium nitrate, sodium nitrate or  
triple super phosphate fertilizers with VELPAR® L as  
herbicidal action will be lost.

• Do not use DuPont™ VELPAR® L in nurseries, seedbeds, or  
ornamental plantings.  
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.  
• 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.  
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.  
–Applications made when the soil is saturated with water and  
rain is imminent within 24 hours.  
USE PRECAUTIONS  
YELLOW POPLAR PLANTINGS  
–Applications to soils high in organic matter (greater  
than 5%).  
• Following harvest, allow stumps and injured trees sufficient  
time to adequately resprout before applying VELPAR® L.  
• 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  
• Refer to package labels for information regarding spray  
drift management.  
–On loamy sand or sandy loam with less than 2% organic

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  
 
• Following mechanical cutting or clearing, allow stumps and  
injured trees sufficient time to adequately resprout before  
applying VELPAR® L.  
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.  
• 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.  
Boom Height (aircraft) - Application more than 10 feet  
above the canopy increases the potential for spray drift.  
Weed and brush control results from spring applications  
depend on sufficient moisture to activate VELPAR® L.  
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.  
• 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.  
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.  
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.  
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  
IMPORTANCE OF DROPLET SIZE  
When making applications in hot and dry conditions, set up  
equipment to produce larger droplets to reduce effects of  
evaporation.  
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.  
SURFACE TEMPERATURE INVERSIONS  
Drift potential is high during a surface temperature inversion.  
Surface inversions restrict vertical air mixing, which causes  
small suspended droplets to remain close to the ground and  
move laterally in a concentrated cloud. Surface inversions are  
characterized by increasing temperature with altitude and are  
common on nights with limited cloud cover and light to no  
wind. They begin to form as the sun sets and often continue  
into the morning. Their presence can be indicated by ground  
fog; however, if fog is not present, inversions can also be  
identified by the movement of smoke from a ground source or  
an aircraft smoke generator. Smoke that layers and moves  
laterally in a concentrated cloud (under low wind conditions)  
indicates a surface inversion, while smoke that moves upward  
and rapidly dissipates indicates good vertical air mixing.  
CONTROLLING DROPLET SIZE  
GENERAL TECHNIQUES  
Volume - Use high flow rate nozzles to apply the highest  
practical spray volume. Nozzles with higher rated flows  
produce larger droplets.  
Pressure - Use the lower spray pressures recommended for  
the nozzle. Higher pressure reduces droplet size and does not  
improve canopy penetration. When higher flow rates are  
needed, use a higher-capacity nozzle instead of increasing  
pressure.  
SHIELDED SPRAYERS  
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 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.  
SENSITIVE AREAS  
CONTROLLING DROPLET SIZE - AIRCRAFT  
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).  
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.
