APPLICATION INFORMATION  
GENERAL INFORMATION  
VELPAR® DF may be applied by ground equipment and,  
where permitted, aerial equipment. Use rates, minimum spray  
gallonage, and other application information are described for  
various uses.  
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.  
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® 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.  
MIXING  
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.  
VELPAR® DF is noncorrosive to equipment.  
Caution should be exercised when applying VELPAR® DF  
near desirable trees or shrubs as they can absorb VELPAR®  
DF through roots extending in to treated areas.  
RESISTANCE  
Refer to supplemental labeling entitled “VELPAR® DF  
Herbicide Chemigation Use on Alfalfa” for use directions  
for chemigation. Do not apply this product through any  
irrigation system unless the supplemental labeling on  
chemigation is followed.  
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.  
ENVIRONMENTAL CONDITIONS  
AND BIOLOGICAL ACTIVITY  
VELPAR® DF is absorbed through the roots and foliage.  
Moisture is required to activate VELPAR® DF in the soil.  
Best results are obtained when the soil is moist at the time  
of application and 1/4–1/2 inches of rainfall occurs within 2  
weeks after application.  
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.  
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  
moisture. Herbicidal activity may be reduced when vegetation is  
dormant, semi-dormant, or under stress(e.g. temperature or  
moisture).  
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.  
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.  
INTEGRATED PEST MANAGEMENT  
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.  
This product may be used as part of an Integrated Pest  
Management (IPM) program that can include biological,  
cultural, and genetic practices aimed at preventing  
economic pest damage. IPM principles and practices  
include field scouting or other detection methods, correct  
target pest identification, population monitoring, and  
treating when target pest populations reach locally  
determined action thresholds. Consult your state cooperative  
extension service, professional consultants or other qualified  
authorities to determine appropriate action treatment  
threshold levels for treating specific pest/crop systems in  
your area.  
The degree and duration of control will depend on the following:  
• Use rate  
Weed spectrum and size at time of application  
• 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  
ranges.

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.  
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, cautions and special precautions on this label  
must be followed along with state regulations relating to dry  
bulk fertilizer blending, impregnating and labeling.  
CHRISTMAS TREES  
VELPAR® DF is recommended for control of certain weeds  
where the following species are grown:  
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.  
Austrian pine  
Douglas fir  
Noble fir  
Ponderosa pine  
Scotch pine  
Sitka spruce  
(western US only)  
Grand fir  
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.  
Loblolly pine  
Do not use VELPAR® DF on Christmas trees in the following  
states:  
Alabama  
Arkansas  
Louisiana  
Maine  
New Jersey  
New York  
Texas  
Vermont  
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  
immediately.

per 100 gal of water. Apply a sufficient volume to wet the weed  
foliage. Do not exceed 100 gal of spray per treated acre. Use the  
lower concentration on coarse-textured soils and the higher  
concentration on fine-textured soils.  
APPLICATION TIMING  
- USE RATES - MIXING INSTRUCTIONS  
Apply a single treatment of VELPAR® DF per year using a  
fixed-boom sprayer and a minimum of 25 gal per acre  
unless otherwise directed.  
Note: Since it is difficult to calibrate “spot” knapsack  
applications, extra care must be taken not to exceed the rate  
equivalent of the maximum of 2/3 lb VELPAR® DF per acre.

Temporary crop chlorosis may result from postemergence  
applications to emerged sugarcane.  
Do not apply more than 2 1/3 lb of DuPont™ VELPAR® DF  
per acre per season.  
The tank mix combination may also be used as a post-  
directed/layby application. For best weed control, post-  
directed/layby applications should be made prior to weed  
germination. Post-directed/layby applications are required  
when the sugarcane plants reach or exceed a height of 18  
inches. Post-directed/layby applications should be directed  
at the base of the sugarcane plants so the spray does not  
contact green leaves or the plant whorl.

TANK MIXTURES (LOUISIANA AND TEXAS)  
A tank mixture of VELPAR® DF at 0.67 pounds per acre  
plus diuron (“Karmex” DF or “Direx” DF) at 2.25 lbs per  
acre may be applied to newly planted sugarcane prior to  
crop emergence or to rattoon (stubble) sugarcane following  
harvest for improved control of annual sedge, cutleaf  
eveningprimrose, red morningglory, pitted morningglory,  
Texas panicum, smellmelon, swinecress, toadflax and also  
provide additional suppression of itchgrass.  
• Do not use VELPAR® DF on gravelly or rocky soils,  
thinly covered subsoils, or coarse-textured soils (sands to  
sandy loams) with less than 1% organic matter.  
• Temporary chlorosis of the crop may result from  
application over emerged cane. Applications during active  
cane growth should be directed to cover the weeds and  
soil while minimizing crop contact.  
• Do not use VELPAR® DF on varieties known to be  
susceptible to weed killers.  
An early Spring application of the tank mix combination  
may be used postemergence (over the top) of sugarcane  
until it reaches a height of 18 inches. If weeds are present at  
the time of application, a non-ionic surfactant at the use rate  
of 0.25% V/V or a crop oil concentrate at the use rate of 1%  
V/V is recommended. If a tank mix partner is being used,  
Extremely heavy rainfall after application may result in  
poor weed control and/or crop injury, especially if the  
application is made to dry soil.

Applications made to shelter wood sites may also result in  
mortality to over-story conifers. Factors that may influence  
conifer sensitivity in these sites could include application rate,  
conifer species, soil characteristics, uniformity of spray distri-  
bution across the treatment swath and environmental stress.

*
Partial Control or Suppression - Specie suppression or partial  
control 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.  
In areas where other conifer species may be mixed in with the  
conifers listed above, VELPAR® DF may be applied if the user  
has prior experience with VELPAR® DF on the other conifer  
species. With no prior experience, it is recommended that either  
a small area of plantings be tested for conifer safety prior to  
treating larger areas, or make no application of VELPAR® DF  
in these areas within the site preparation area. Conifer species  
that are sensitive to VELPAR® (hexazinone) DF, such as, sugar  
pine and western larch, require 18 months before interplanting  
on treated sites.  
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  
vegetation only after any residual stand is completely  
defoliated, at least twice, allowing for sufficient root uptake of  
VELPAR® DF. In the West, results may take one to two years  
in areas of low rainfall.

only after brush has completely defoliated at least once,  
allowing sufficient root uptake of VELPAR® DF (usually  
60-90 days after adequate rainfall).  
SPRAY EQUIPMENT  
When applied as a liquid spray using water as the carrier,  
DuPont™ VELPAR® DF may be applied by ground  
equipment or by air (helicopter only).  
• Before using “Tordon 101” Mixture, read and carefully  
observe the cautionary statements and all other information  
appearing on the product label. “Tordon 101” Mixture is a  
restricted use pesticide, for retail sale to and use only by  
certified applicators or persons under their direct  
supervision and only for those uses covered by certified  
applicator’s certification.  
MIXING INSTRUCTIONS

MIXING INSTRUCTIONS  
SINGLE STEM (BASAL SOIL)  
For ground application, use enough water for thorough  
coverage, usually a minimum of 25 gal per acre. For aerial  
applications, use at least 5 gal of water per acre. For best  
results, full foliar coverage is required.  
Mix 2 2/3 pounds of VELPAR® DF with sufficient water to  
make one gallon of suspension and thoroughly agitate.  
Apply the VELPAR® DF suspension with an exact-delivery  
handgun applicator. This equipment delivers a thin stream  
of predetermined volume when triggered. Apply the  
VELPAR® DF suspension at the rate of 2 to 4 ml for each  
inch of stem diameter at breast height. Direct the treatment  
to the soil within 3 feet of the root collar of woody plants to  
be controlled.  
USE PRECAUTIONS  
- VELPAR® DF + “Tordon 101” Mixture  
• To avoid injury, do not plant pine before the following  
intervals following application with “Tordon 101” Mixture:  
–Southern states - 6 months  
–Lake states - 9 months  
–Northeastern states - 9 months  
• Burning treated sites after initial contact (browning) effect  
on foliage may result in poor control. Burn the vegetation

For multi-stemmed and low-growing brush that have stem  
diameters that are difficult to determine, apply the  
DuPont™ VELPAR® DF suspension at the rate of 2 to 4 ml  
per 3 feet of canopy width. For tall, slender (columnar)  
brush types, apply 4 to 8 ml per 3 feet of height. Base the  
rate on whichever canopy dimension is greater (width or  
height).  
made after bud break, use directional spray equipment to  
prevent contact with conifer foliage, as injury may result.  
Snowbelt (areas of low spring rainfall): For best results,  
apply in the fall before soil freezes and after the final resting  
bud has hardened on the conifers. Or, spring applications  
may be made after snow cover melts in anticipation of  
rainfall prior to conifer budbreak. Brush control results  
from spring treatments will be dependent on sufficient  
rainfall following application to activate VELPAR® DF.  
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.

FORESTRY—IMPREGNATION ON DRY BULK  
FERTILIZER  
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.  
VELPAR® DF is recommended for impregnating or coating  
dry bulk fertilizer to be applied on forested sites for the  
establishment or release of conifer plantations (except  
longleaf pine) as specified on this label.  
PLANTS CONTROLLED  
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 DuPont™ VELPAR®  
DF.  
Fertilizer impregnated with VELPAR® DF is recommended  
for the control and suppression of the weeds and brush  
identified for the specific applications on this label. Consult  
the appropriate segment of this label to determine the  
appropriate rate of VELPAR® DF to be applied per acre.  
Apply this amount of VELPAR® DF to the volume of  
fertilizer to be applied per acre.  
USE RATES  
IMPREGNATION EQUIPMENT  
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.  
To impregnate or coat the fertilizer use a system consisting  
of conveyor or closed drum used to blend dry bulk fertilizer.  
IMPREGNATION INSTRUCTIONS  
To impregnate dry bulk fertilizer with VELPAR® DF, mix  
the amount as prescribed above in a sufficient quantity of  
water to uniformly coat the desired amount of fertilizer.  
Suspensions of VELPAR® DF will require thorough  
agitation.

BROADCAST  
Apply 5 1/3 to 10 2/3 lb of DuPont™ VELPAR® DF per acre  
as a coarse spray by ground equipment or 5 1/3 to 8 lb per  
acre by air (helicopter only). Use enough water for thorough  
coverage. For ground equipment, usually a minimum of 25  
gal per acre. For aerial equipment, usually a minimum of 10  
gal per acre. Higher volumes of water may be needed when  
water temperatures are cold or the higher rates of VELPAR®  
DF are used.  
• Do not use VELPAR® DF on frozen soils.  
• Do not use VELPAR® DF 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® DF.  
• 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.  
BASAL (SOIL)  
SINGLE STEM - Mix 2 2/3 pounds of VELPAR® DF with  
sufficient water to make one gallon of suspension and  
thoroughly agitate. Apply the VELPAR® DF suspension with  
an exact-delivery handgun applicator. This equipment  
delivers a thin stream of predetermined volume when  
triggered. Apply the VELPAR® DF suspension at the rate of  
2 to 4 ml for each inch of stem diameter at breast height.  
Direct the treatment to the soil within 3 feet of the root collar  
of woody plants to be controlled.  
PASTURE  
VELPAR® DF is recommended for control of brush and  
weeds in pasture.  
BERMUDAGRASS/BAHIAGRASS PASTURES  
VELPAR® DF is recommended for control of smutgrass and  
other weeds in established stands of bermudagrass and  
bahiagrass.  
For multi-stemmed and low-growing brush that have stem  
diameters that are difficult to determine, apply the VELPAR®  
DF suspension at the rate of 2 to 4 ml per 3 feet of canopy  
width. For tall, slender (columnar) brush types, apply 4 to 8  
ml per 3 feet of height. Base the rate on whichever canopy  
dimension is greater (width or height).  
APPLICATION TIMING  
Make a single application of VELPAR® DF per year when  
weeds are actively growing.  
WEEDS CONTROLLED - USE RATES  
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.  
VELPAR® DF effectively controls the following weeds at the  
rates shown. Use a lower rate on coarse-textured soils (sand to  
sandy loam). Use the higher rate on fine-textured soils (clay  
loam to clay) and on soils high in organic matter.

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.

IMPORTANCE OF DROPLET SIZE  
Locust  
Yellow poplar  
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

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  
• 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.  
not interfering with uniform deposition of the product.  
SPRAY TANK CLEAN OUT  
CONTROLLING DROPLET SIZE - AIRCRAFT  
Thoroughly clean all traces of DuPont™ VELPAR® DF  
from application equipment immediately after use. Flush the  
tank, pump, hoses, and boom with several changes of water  
after removing nozzle tips and screens (clean these parts  
separately). Dispose of the equipment wash water by  
applying it to a use-site listed on this label.  
• 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.  
STORAGE AND DISPOSAL  
Do not contaminate water, food, or feed by storage or  
disposal.  
BOOM LENGTH AND HEIGHT  
Pesticide Storage: Store product in original container  
only. Store in a cool, dry place.  
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.  
Pesticide Disposal: Waste resulting from the use of  
this product may be disposed of on site or at an  
approved waste disposal facility.  
Boom Height (aircraft) - Application more than 10 feet

sack by shaking and tapping sides and bottom to  
loosen clinging particles. Empty residue into manufac-  
turing or application equipment. Then dispose of sack  
in a sanitary landfill or by incineration if allowed by

above the canopy increases the potential for spray drift.  
Boom Height (ground) Setting the boom at the lowest  
labeled height (if specified) which provides uniform coverage  
reduces the exposure of droplets to evaporation and wind.  
The boom should remain level with the crop and have  
minimal bounce.  
WIND  
Drift potential increases at wind speeds of less than 3 mph (due  
to variable direction and inversion potential) or more than 10  
mph. However, many factors, including droplet size and  
equipment type determine drift potential at any given wind  
speed. AVOID GUSTY OR WINDLESS CONDITIONS.  
Note: Local terrain can influence wind patterns. Every  
applicator should be familiar with local wind patterns and how  
they effect spray drift.

SURFACE TEMPERATURE INVERSIONS  
NOTICE TO BUYER: Purchase of this material does not  
confer any rights under patents of countries outside of the  
United States.  
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
