GENERAL INFORMATION  
• Environmental conditions at and following treatment  
Where a rate range is shown, use the higher levels of the dosage  
range on hard-to-control species, fine-textured soils, or soils  
containing greater than 5% organic matter or carbon. Use the  
lower levels of the dosage range on coarse-textured soils and/or  
on soils low in organic matter. Refer to specific uses for rate

DuPont™ VELPAR® DF herbicide is a water-dispersible  
granule that is mixed in water and applied as a spray for  
weed control in certain crops, Christmas trees, forestry site  
preparation and release areas, and industrial areas. It may  
also be applied as a basal soil treatment for brush control in  
reforestation areas, rangeland, pastures and noncrop areas.  
APPLICATION INFORMATION  
VELPAR® DF is an effective general herbicide providing  
both contact and residual control of many annual and  
biennial weeds and woody plants. It is also effective for  
control of most perennial weeds.  
VELPAR® DF may be applied by ground equipment and,  
where permitted, aerial equipment. Use rates, minimum spray  
gallonage, and other application information are described for  
various uses.  
VELPAR® DF is noncorrosive to equipment.  
Dispose of the equipment washwater by applying it to a use-  
site listed on this label or in accordance with directions given  
in the “Storage and Disposal” section of this label.  
Caution should be exercised when applying VELPAR® DF  
near desirable trees or shrubs as they can absorb VELPAR®  
DF through roots extending in to treated areas.  
Before spraying, calibrate equipment to determine the quantity  
of water necessary to uniformly and thoroughly cover the  
vegetation and soil in a measured area to be treated. Make sure  
the volume of water is sufficient to completely suspend the  
VELPAR® DF.  
This product may be applied on conifer plantations and non-  
crop sites that contain areas of temporary surface water  
caused by collection of water between planting beds, in  
equipment ruts, or in other depressions created by  
management activities. It is permissible to treat intermittent  
drainage, intermittently flooded low lying sites, seasonally  
dry flood plains and transitional areas between upland and  
lowland sites when no water is present. It is also permissible  
to treat marshes, swamps and bogs after water has receded,  
as well as seasonally dry flood deltas. DO NOT make  
applications to natural or man-made bodies of water such as  
lakes, reservoirs, ponds, streams and canals.  
TANK MIXTURES  
VELPAR® DF herbicide may be tank mixed with other  
herbicides and /or adjuvants registered for the uses (crops)  
specified in the label.  
Refer to the label of the tank mix partner(s) for any additional  
use instructions or restrictions.  
RESISTANCE  
ENVIRONMENTAL CONDITIONS  
AND BIOLOGICAL ACTIVITY  
When herbicides that affect the same biological site of  
action are used repeatedly over several years to control the  
same weed species in the same field, naturally-occurring  
resistant biotypes may survive a correctly applied herbicide  
treatment, propagate, and become dominant in that field.  
Adequate control of these resistant weed biotypes cannot be  
expected. If weed control is unsatisfactory, it may be  
necessary to retreat the problem area using a product  
affecting a different site of action.  
VELPAR® DF is absorbed through the roots and foliage.  
Moisture is required to activate VELPAR® DF in the soil.  
Best results are obtained when the soil is moist at the time  
of application and 1/4–1/2 inches of rainfall occurs within 2  
weeks after application.  
For best results, apply VELPAR® DF preemergence or  
postemergence when weeds are less than 2 inches in height or  
diameter. Herbicidal activity is most effective under conditions  
of high temperature (above 80 °F), high humidity, and good soil To better manage herbicide resistance through delaying the  
moisture. Herbicidal activity may be reduced when vegetation is proliferation and possible dominance of herbicide resistant  
dormant, semi-dormant, or under stress(e.g. temperature or  
moisture).  
weed biotypes, it may be necessary to change cultural  
practices within and between crop seasons such as using a  
combination of tillage, retreatment, tank-mix partners  
and/or sequential herbicide applications that have a different  
site of action. Weed escapes that are allowed to go to seed  
will promote the spread of resistant biotypes.  
Herbicidal activity will usually appear within 2 weeks after  
application to susceptible plants under warm, humid conditions;  
while 4–6 weeks may be required when weather is cool or dry,  
or when susceptible plants are under stress. If rainfall after  
application is inadequate to activate VELPAR® DF in the soil,  
plants may recover from contact effects and continue to grow.  
It is advisable to keep accurate records of pesticides applied  
to individual fields to help obtain information on the spread  
and dispersal of resistant biotypes. Consult your  
agricultural dealer, consultant, applicator, and/or appropriate  
state agricultural extension service representative for  
specific alternative cultural practices or herbicide  
recommendations available in your area.  
On woody plants, symptoms usually appear within 3–6 weeks  
after sufficient rainfall has carried the herbicide into the root  
zone during periods of active growth. Defoliation and  
subsequent refoliation may occur, but susceptible plants are  
killed.  
The degree and duration of control will depend on the following:

SPRINKLER CHEMIGATION  
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-  
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  
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.  
turers or other experts.  
A person knowledgeable of the chemigation system and  
responsible for its operation, or under the supervision of the  
responsible person, shall shut the system down and make  
necessary adjustments should the need arise.  
DORMANT APPLICATIONS  
Select the appropriate rate (see Use Rates section) for soil  
texture and organic matter content using 0.25” to 0.75” of  
sprinkler irrigation as a continuous injection during the  
application. Best results are obtained when soil is moist at  
time of application, and when weeds have not germinated or  
are less than 2” tall or across.  
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.  
MIXING INSTRUCTIONS  
1. Fill the supply tank 1/4 to 1/3 full of water.  
2. While agitating, add the required amount of VELPAR®  
DF and continue agitation until the VELPAR® DF is  
fully dispersed, at least 5 minutes.  
3. Once the VELPAR® DF is fully dispersed, maintain  
agitation and continue filling tank with water.  
VELPAR® DF should be thoroughly mixed with water  
before adding any other material.  
4. As the tank is filling, add tank mix partners (if desired).  
Follow use precautions and directions on the tank mix  
partner label.  
5 After thorough mixing, the agitation system can be  
stopped to prevent excessive foaming in the tank. Once  
thoroughly mixed the solution in the supply tank does not  
require additional agitation unless specified on the  
companion products label. If foaming occurs in the  
injection supply tank, a defoaming agent (defoamer) may  
be added.  
6. Apply VELPAR® DF spray mixture within 48 hours of  
mixing to avoid product degradation.  
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.

FLOOD IRRIGATED ALFALFA  
POSTING OF AREAS TO BE TREATED  
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.  
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 indefinitely as long as they are composed of  
materials to prevent deterioration and maintain legibility  
for the duration of the posting period.  
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, impreg-  
nating 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.  
• 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.  
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  
equipment. Uniform impregnation of VELPAR® DF 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® DF, mix and impregnate the fertilizer  
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  
use rate does not exceed 2/3 lb per acre. Sites with use  
rates higher than 2/3 lb per acre should not be replanted to  
any root crop within 2 years after application of DuPont™  
VELPAR® DF, or unacceptable crop injury may result.  
immediately.  
Apply impregnated fertilizer as soon as possible after impreg-  
nation for optimum performance.  
Select the rate of VELPAR® DF to apply per acre from the  
appropriate section of this label. Then refer to the rate chart  
below to determine the amount of VELPAR® DF that should  
be impregnated on a ton of dry bulk fertilizer, based on the  
amount of fertilizer to be distributed in one acre.  
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.  
• 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.

- vegetative top growth of alfalfa has lateral development of  
secondary growth  
- alfalfa is healthy and vigorous, not growing under stress  
from insect, disease, winter injury or other types of stress.  
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.  
Injury may result to alfalfa plants that fail to meet these  
growth criterion listed above.  
• Do not use VELPAR® DF on seedling alfalfa, alfalfa-grass  
mixtures, or other mixed stands as injury may result to the  
seedling alfalfa or companion crop.  
• Do not use a surfactant with VELPAR® DF when treating  
non-dormant alfalfa.  
USE PRECAUTIONS - ALFALFA  
• Best results are obtained when 1/2–1 inches of rainfall or  
sprinkler irrigation occurs within two weeks after  
application, when soil is moist at time of application, and  
when weeds have not germinated or are less than 2 inches in  
height or diameter. Heavy rainfall or excessive irrigation  
after application may result in crop injury or poor  
performance of the herbicide.  
• Do not use VELPAR® DF on gravelly or rocky soils,  
exposed subsoils, hardpan, sand, poorly drained soil, or  
alkali soils.  
SEED ALFALFA (CALIFORNIA ONLY)  
ADDITIONAL USE PRECAUTIONS  
• Do not use VELPAR® DF on fields with sandy loam or  
loamy sand soils having less than 1% organic matter.  
On soils high in organic matter (greater than 5%), the  
effectiveness of VELPAR® DF can be significantly  
reduced and weed control may be unsatisfactory.  
• Do not exceed 2/3 pound per acre on fields with sandy loam  
or loamy sand soils having 1–2% organic matter.  
Crop injury, including mortality, may result in fields with  
restricted root growth due to non-uniform soil profiles  
such as gravel bases and clay lenses.  
• Do not exceed 2/3 pound per acre on seed alfalfa that has  
been established for only one growing season.  
Crop injury may result if hot weather, mid-to-high 90  
degree range or higher, occurs within a few days after  
application.  
BLUEBERRY  
HIGH BUSH BLUEBERRIES  
• Do not apply to snow-covered or frozen ground.  
VELPAR® DF is recommended for control of certain  
herbaceous and woody weeds in established high bush  
blueberry fields.  
• Since the effect of VELPAR® DF on alfalfa varies with soil  
conditions, uniformity of application, and environmental  
conditions, growers should limit their first use to small  
areas.  
APPLICATION INFORMATION  
VELPAR® DF may be applied to high bush blueberries that  
have been established for 3 or more years. Apply  
VELPAR® DF in the spring before blueberry leaf  
emergence. Direct the spray solution towards the soil and  
weeds.  
• 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® DF applications.  
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.  
• 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

space application - Apply VELPAR® DF as a directed  
spray 3–10 months after planting in 50–200 gallons of water  
per acre (broadcast basis) at the rate of 1/3 - 2 1/3 pounds  
per acre (broadcast basis) using a stroller boom or knapsack.  
• 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® DF.  
• Do not cut treated vegetation for forage or hay nor graze  
domestic animals on treated areas for 60 days following  
application.  
Directed spot treatments for perennial grasses before  
floral induction - Spray perennial grasses postemergence to  
wet (50–200 gallons per acre depending on size) with  
1 1/3 - 2 1/3 pounds per 100 gallons of water as a spot  
treatment.  
• 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® DF at 2 1/3 - 4 8/10 pounds per acre in 100–400

has prior experience with VELPAR® DF on the other conifer  
species. With no prior experience, it is recommended that either  
a small area of plantings be tested for conifer safety prior to  
treating larger areas, or make no application of VELPAR® DF  
in these areas within the site preparation area. Conifer species  
that are sensitive to VELPAR® (hexazinone) DF, such as, sugar  
pine and western larch, require 18 months before interplanting  
on treated sites.

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

For multi-stemmed and low-growing brush that have stem  
defoliated, at least twice, allowing for sufficient root uptake of diameters that are difficult to determine, apply the

of canopy width. For tall, slender (columnar) brush types,  
apply 4 to 8 ml per 3 feet of height. Base the rate on  
whichever canopy dimension is greater (width or height).  
Apply the lower volumes for coarse textured soils or soils  
with low organic matter soils and the higher volumes for  
fine textured soils or soils with high organic matter.  
SPRAY EQUIPMENT  
When applied as a liquid spray using water as the carrier,  
VELPAR® DF may be applied by ground equipment or by air  
(helicopter only).  
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.  
When treating brush that requires more than a single  
delivery of the VELPAR® DF suspension, apply subsequent  
deliveries equally spaced around the target plant. If treating  
brush on sloping sites, apply most of the suspension on the  
uphill side of the stem. If treating resprouts from brush  
disturbed by cutting or other mechanical methods, the rate  
of application should be proportional to the original tree  
size, not just the size of sprout regrowth.  
GRID APPLICATION  
Mix 2 2/3 pounds of VELPAR® DF with sufficient water to  
make one gallon of suspension and thoroughly agitate.  
Intermittent agitation may be required to maintain the  
VELPAR® DF in suspension.  
USE PRECAUTIONS  
SITE PREPARATION  
Where burning is desired, burn the vegetation only after any  
residual brush has completely defoliated, at least twice,  
allowing for sufficient root uptake of VELPAR® DF.  
Apply the VELPAR® DF suspension directly to the soil  
surface in a grid pattern using an exact delivery handgun  
applicator. This equipment delivers a thin stream of  
predetermined volume. VELPAR® DF should be applied  
during the period from hardwood bud break to early  
summer.  
Following harvest, allow sufficient time for stumps and  
injured trees to adequately resprout before applying  
VELPAR® DF.  
Application rate 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 this label  
as “partial control or suppression” predominate.

USE PRECAUTIONS  
IMPREGNATED FERTILIZER FOR

• 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.  
–On gravelly or rocky soils, exposed subsoils, clay knobs,  
sand, or sandy soil with 85% or more sand.  
• The dry fertilizer must be properly impregnated and  
uniformly applied to avoid pine injury/mortality and poor  
weed and brush control.  
• Do not cut treated vegetation for forage or hay nor graze  
domestic animals on treated areas for 60 days following  
application.  
• Uniform and precise application of the impregnated  
fertilizer is essential for satisfactory weed and brush  
control and to minimize pine injury. Overlaps or skips  
between adjoining swaths or non-uniform distribution of  
impregnated fertilizer within the swath will deliver poor  
results and may result in pine injury or mortality.  
YELLOW POPLAR PLANTINGS  
VELPAR® DF is recommended for the control of  
herbaceous weeds in the establishment of yellow poplar  
plantations. Applications may be made over the top of  
planted seedlings after the soil has settled around the root  
systems but before the seedlings have broken dormancy  
(bud break). A subsequent application may be made before  
dormancy break in the Spring of the second year. USE  
RATES: Use the rate range specified in the "RELEASE-  
HERBACEOUS WEED CONTROL" section for pine  
plantations - eastern US.  
• 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.  
For ground application, use sufficient spray volume for  
uniform and thorough coverage of the site to be sprayed,  
usually a minimum of 25 gallons per acre. For aerial  
applications, use a minimum of 5 gallons of water per acre.  
For broader spectrum control VELPAR® DF may be tank  
mixed with DuPont™ ESCORT® XP herbicide. Add  
ESCORT® XP at a rate of 1/2 ounce per acre with the  
prescribed rate of VELPAR® DF.  
• 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:  
USE PRECAUTIONS  
YELLOW POPLAR PLANTINGS  
• Applications of VELPAR® DF and tank mixes of  
VELPAR® DF and DuPont™ ESCORT® XP made to  
yellow poplar seedlings that are suffering from loss of  
vigor caused by insects, disease, drought, winter damage,  
animal damage, excessive soil moisture, planting shock or  
other stresses may injure or kill the seedlings.  
–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%)  
• Following harvest, allow stumps and injured trees  
sufficient time to adequately resprout before applying  
VELPAR® DF.  
• Applications of VELPAR® DF and tank mixes of  
VELPAR® DF and ESCORT® XP should only be made  
after adequate rainfall has closed the planting slit and  
settled the soil around the roots following transplanting.  
• Where burning is desired, burn vegetation after any brush  
has completely defoliated, at least twice, allowing for  
sufficient root uptake of VELPAR® DF.  
• The use of surfactant with VELPAR® DF is not  
recommended for applications made over the tops of  
seedlings.  
• Do not use VELPAR® DF on frozen soils; use in spring  
after snow melt.  
• 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.  
• 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® DF.  
• When applying VELPAR® DF after transplanting, wait  
until rainfall has settled the soil around the base and root  
systems of the transplants before making the treatment.  
PASTURE / RANGELAND  
• Crop injury may occur when VELPAR® DF is used:  
VELPAR® DF is recommended for control of brush and  
weeds in pasture.  
–On trees that show poor vigor, insect damage, disease,  
winter injury, or other stress conditions  
–On any soil containing less than 1% organic matter  
BERMUDAGRASS / BAHIAGRASS  
–On loamy sand or sandy loam with less than 2% organic  
matter, except Jeffrey pine and Ponderosa pine  
VELPAR® DF is recommended for control of smutgrass and  
other weeds in established stands of bermudagrass and  
bahiagrass.  
–On conifer foliage after conifer bud break

CONTROLLING DROPLET SIZE  
- GENERAL TECHNIQUES  
USE PRECAUTIONS  
NON-CROP  
• Injury to or loss of desirable trees or other plants may result if  
DuPont™ VELPAR® DF is applied or if equipment is  
drained or flushed on or near desirable trees or other plants,  
on areas where their roots may extend, or in locations where  
the chemical may be washed or moved into contact with their  
roots.  
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.  
• Application spray drift may injure desirable plants.  
• Poor weed and brush control may result from the following:  
–Use on poorly drained sites  
• 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.  
–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%).  
CONTROLLING DROPLET SIZE - AIRCRAFT  
• Number of Nozzles - Use the minimum number of  
nozzles with the highest flow rate that provide uniform  
coverage.  
• Following mechanical cutting or clearing, allow stumps and  
injured trees sufficient time to adequately resprout before  
applying VELPAR® DF.  
• Nozzle Orientation - Orienting nozzles so that the spray is  
emitted backwards, parallel to the airstream will produce  
larger droplets than other orientations.  
• Do not use VELPAR® DF on frozen soils.  
• Do not use VELPAR® DF on lawns, driveways, tennis courts,  
or other residential or recreational areas.  
• Nozzle Type - Solid stream nozzles (such as disc and core  
with swirl plate removed) oriented straight back produce  
larger droplets than other nozzle types.  
Weed and brush control results from spring applications  
depend on sufficient moisture to activate VELPAR® DF.  
BOOM LENGTH AND HEIGHT  
• Do not cut treated vegetation for forage or hay nor graze  
domestic animals on treated areas for 60 days following  
application. For rates above 8 lb per acre, do not cut treated  
vegetation for forage or hay nor graze domestic animals for 1  
year.  
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.  
ADDITIONAL USE INFORMATION  
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.  
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.  
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.  
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.  
Note: Local terrain can influence wind patterns. Every  
applicator should be familiar with local wind patterns and how  
they effect spray drift.  
TEMPERATURE AND HUMIDITY  
When making applications in hot and dry conditions, set up  
equipment to produce larger droplets to reduce effects of  
evaporation.  
23  
Download from Www.Somanuals.com. All Manuals Search And Download.  
SURFACE TEMPERATURE INVERSIONS  
STORAGE AND DISPOSAL  
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
