PRODUCT INFORMATION
DuPont™ DPX-121 herbicide must be used only in accordance with instructions on this label or in supplemental DuPont
publications. DuPont will not be responsible for losses or damage resulting from use of this product in any maijqerjif^
specifically specified by DuPont. c
DPX-121 herbicide is a water soluble granule containing 33.4% active ingredient by weight. DPX-Ol K a selective
herbicide for burndown and residual control of certain annual grass and broadleaf weeds when aprjlied p(replantor- c ^ <-
preemergence to field corn. Residual weed control is dependent on rainfall or sprinkler irrigation "for* herbicide activation.
DPX-121 herbicide may be applied in tank mixtures with other herbicides labeled for use in the intended crop. However,J ^^ C C C C C ^OGUO
in the case of tank mixes with other herbicides, the most restrictive label must be followed. o c G C C C C C
DPX-121 is absorbed through the roots and leaf tissue of plants, rapidly inhibiting the growth of susceptible weeds, <•.
Rainfall or sprinkler irrigation is needed to move DPX-121 into the soil. Susceptible weeds will generally not emerge irom
preemergence application. In some cases susceptible weeds may germinate and emerge a few days after application, but
growth then ceases and leaves become chlorotic three to five days after emergence. Death of leaf tissue and growing <pbint
will follow in some species, while others will remain green but stunted and noncompetitive.
The herbicidal action of DPX-121 may be less effective on weeds stressed from adverse environmental conditions (such as
extreme temperatures or moisture), abnormal soil conditions, or cultural practices.

RESTRICTIONS
• Do not-apply the organophosphate insecticide "Counter" within 60 days of a preplan! or preemerge application of '
DuPont™ DPX-121 since crop injury may result. > - . "•',.„
• Do not apply more than a total'of 1.6 oz active ingredient rimsulfuron p'er acre per crop year to field corn from all -
sources. This includes combinations,of preplan! and preemergence applications of DPX-121 and DiiPon!™ "
PREQUEL®, as well as rimsulfuron from postemergence application(s) of products such as DuPont™ REALM® Q,
• DuPont™ STEADFAST® .Q or DuPont™ RESOLVE® Q. , . , -
• Do not plant any other crop besides corn, potatoes or soybeans the following season if applying DPX-121 and
following with PREQUEL®, .REALM® Q, RESOLVE® Q or STEADFAST® Q.
• Do not apply preemergence on com when planted to coarse textured soils (sand, loamy sand or sandy loam) with '
less than 1% organic matter. •' - „ -/ ,
• Do not apply postemergence to any crop. . " , " ' - , • '
• Do not graze, feed forage, grain or fodder (stover) from treated areas to livestock within 30 days of DPX-121-
application. -1 " . -.. ^ •
-Injury or loss of-desirable trees'or vegetation may result from failure to observe the following: - •''",'',
• Do not apply DPX-121 or drain or flush,application equipment on or.near desirable.trees or other plants, or on areas
where their roots may extend,' or in locations where the chemical may be washed or moved into contact with their -
-roots/ - '. _ '
• Do not use on lawns, walks, driveways^ tennis courts, or similar areas. ^ '
• Do not contaminate any body of water. \ •
PRECAUTIONS
• Allow at least 3 weeks between preemergence applications of DPX-121 and postemergence applications of rimsulfuron
containing products, such as REALM® Q, STEADFAST® Q, or RESOLVE® Q.
• DPX-121 may interact with certain insecticides applied to soybean, cotton, or corn. Crop'response varies with field crop,
insecticide used, insecticide application method, and soil type.
• DPX-121 may be applied to crops previously treated with "Fortress", "Aztec", or "Force" insecticides or other
nonorganophosphate (OP) soil insecticides regardless of soil type.
• Preplant/Preemergence applications of DPX-121 to corn where an application of "Lorsban", or "Thimet" is planned may
cause unacceptable crop injury, especially on soils of less than 4% organic matter.
• Crop injury may occur following an application of DPX-121 if there is a prolonged period of cold weather and/or in
conjunction with wet soils.
• Prevent drift or spray to desirable plants.
• Thoroughly clean application equipment immediately after use. It is recommended to flush the sprayer system and recharge
with clean water when there are extended periods belween DPX-121 applications. (See Sprayer Cleanup section of this label
for instructions).
APPLICATION INFORMATION
Field Corn - Burndown-Preplant-Preemergence
Rate
Apply DPX-121 at 1.5 ounces per acre.
See cumulative rimsulfuron rate limitations noted in this label.
Not all field com varieties have been tested; nor does DuPont have access to all seed company data. Consequently; EJuPont
is not responsible for any crop injury arising from the use of DPX-121 on field corn. When tank mixing check [tfectank: mix
partner label for tolerances and instructions for use. In addition; consult with your local DuPont representative or th,e
DuPont Label Web Site (http://cropprotection.dupont.com/) for any additional supplemental labe^ing'infprmatific relative to
potential corn hybrid sensitivity to DPX-121. cccccc c Lcc1' U C
Timing to Crop cccccc
DPX-121 may be applied preplan! in early spring up to planting, whenever the ground is not froz£u£tbccpntrol efh'efged
weeds and to provide limited residual control of early-emerging weeds. octet, c •
Additionally, DPX-121 may be applied anytime after planting, but before corn emergence. 'j c u 11 <_
Do not apply postemergence to corn. c .
Control of emerged weeds will require the addition of spray adjuvants as noted in this label. c t t L L 'c
Additional Control of Grasses and Broadleaves
DPX-121 may be tank mixed with full or reduced rates of labeled preplant/preemergence grass and broadleaf herbicides
such as atrazine, DuPont™ CINCH® brands and DuPont™ BREAKFREE® brands to provide added residual activity or
additional burndown activity on emerged weeds. Sequential applications of PREQUEL™, CINCH® brands and

r cDuPont™ BREAKFREE® brands may also be made following preplan! applications of DuPont™ DPX-121. Consult tank
mix partner labeling for rate and soil-type restrictions.
Sequential Application
DPX-121 may be used in a sequential herbicide program for corn. Apply DPX - 121 for burndown and residual weed
control, followed by a post, in-crop application of DuPont™ REALM™ Q, DuPont™ RESOLVE® Q or DuPont™
STEADFAST® Q herbicides. Refer to the appropriate product label for use restrictions, appb'cation information, rotational
crop guidelines, and cautionary statements prior to application.
If following DPX 121 with another rimsulfuron containing product such as DuPont™ PREQUEL®, REALM® Q,
RESOLVE® Q or STEADFAST®, only plant corn, potatoes or soybeans the following season.
SPRAY ADJUVANTS
For control of emerged weeds, application of DPX-121 must contain an appropriate adjuvant. When applied in tank mix
combination with a glyphosate (such as ABUNDIT® Extra) or glufosinate herbicide that contains a built-in adjuvant
system, no additional surfactant needs to be added. Consult local DuPont fact sheets, technical bulletins, and service
.policies prior to using other adjuvant systems. Products must contain only EPA-exempt ingredients.
Petroleum Crop Oil Concentrate (COC) or Modified Seed Oil (MSO)
•• Apply at 1% v/v (1 gallon per 100 gallons spray solution) or 2% under arid conditions.
• MSO adjuvants may be used at 0.5% v/v (0.5 gallon per 100 gallons spray solution) if specifically noted on adjuvant
product labeling.
• Oil adjuvants must contain at least 80% high quality, petroleum (mineral) or modified vegetable seed oil with at least
15% surfactant emulsifiers.
Nonionic Surfactant (NIS)
• Apply at 0.25% v/v (1 qt per 100 gal spray solution).
• Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance (HLB) greater
than 12.
Ammonium Nitrogen Fertilizer
In addition to a spray adjuvant, an ammonium nitrogen fertilizer may be used.
• Use 2 qt/acre of a high-quality urea ammonium nitrate (UAN) such as 28%N or 32%N, or 2 Ib/acre of a spray-grade
ammonium sulfate (AMS).
Special Adjuvant Types

Mixing Instructions
Fertilizer Carrier Instructions
DPX-121 may be dissolved in water and added to liquid fertilizer for preemergence application. When using liquid fertilizer as
the carrier, always dissolve DPX-121 in clean water before adding fertilizer solutions. Add the dissolved DPX-121 solution to
the final complete liquid fertilizer mixture - do not add DPX-121 during the fertilizer mixing process.
Always use good agitation while adding the dissolved DPX-121 solution to liquid fertilizers and maintain good agitation until
sprayed. When using liquid fertilizer as the carrier, conduct a compatibility test with all components prior to mixing.
Do not use with spray additives or liquid fertilizer carriers that alter the pH of the spray solution below pH 5.0 or above pH 9.0
as rapid product degradation can occur. Spray solutions of pH 6.0 -8.0 allow for optimum stability of DPX-121.
Water Carrier Instructions
1. Fill the tank 1/3 to 1/2 full of clean water. c c c c c c o
2. While agitating, add the required amount of DPX-121. tccc«-i. c
3. Continue agitation until the DPX-121 is fully dissolved, at least 5 minutes. When the water temperature ir Adf E or
less, it is important to allow agitation and mixing to occur for the full S minutes to ensure ttie^riodrjct is completely
dissolved. i. c c c«.- c
4. Once the DPX-121 is fully dissolved, maintain agitation and continue filling tank with water.l!>;PXt121 sh'ouitf be
thoroughly mixed and dissolved with clean water before adding any other material such as Wk'cer^conditionerS or
other additives. c t c c L ^
5. As the tank is filling, add tank mix partners (if desired) in the proper mixing order.
6. Maintain agitation throughout mixing and application. If the mixture is not continuously agitated, settling could'o^curi 'if
settling occurs, thoroughly re-agitate before using.
7. At the end of the day, or for extended periods of time between DPX-121 applications, it is recommended to flush the boom
hoses and lines of spray solution and recharge with clean water. This will aid in proper sprayer cleanout when concluding
DPX-121 applications before moving on to spray other products /crops.
8. Apply DPX-121 spray mixture within 48 hours of mixing to avoid product degradation.

c cIf the selected companion herbicide has a ground or surface water advisory, consider this advisory when using the companion
herbicide.
Tank Mix Compatibility Testing
Perform ajar test prior to tank mixing to ensure compatibility of DuPont™ DPX-121 and other pesticides. Use a clear quart jar
with lid and mix the tank mix ingredients in their relative proportions. Invert the jar containing the mixture several times and
observe the mixture for approximately 1/2 hour. If the mixture balls-ups, forms flakes, sludge, gel, oily film or layers, or other
precipitates, it is not compatible and the tank mix combination should not be used.
Ground Application
When DPX-121 is used alone, use a minimum of 15 gallons of water per acre (GPA) to ensure thorough coverage of the weeds
and the best performance. When tank mixed with glyphosate, use a minimum of 5 to 10 GPA. For best performance, select
nozzles and pressure that deliver MEDIUM spray droplets, as indicated, for example, by AS ABE Standard S572.1. Nozzles
that deliver COARSE spray droplets may be used to reduce drift, provided spray volume is increased to maintain coverage on
small weeds.
For optimal product performance and minimal spray drift, adjust the spray boom to the lowest possible spray height
recommended in manufacturers' specifications
Aerial Application
Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage at a minimum of 5
GPA.
Do not apply during a temperature inversion, when winds are gusty, or when conditions favor poor coverage and/or offtarget
spray movement.

Notes:
1. Always start with a clean spray tank, hoses, boom and nozzles. Ensure boom sections between end nozzles and the end
of the boom are clean of deposits (it is recommended to remove end caps and visually inspect). If needed, thoroughly
flush rinse water through the boom sections with the end caps removed to ensure booms are clean and free of any residue
or deposits.
2. A steam-cleaning aerial spray tank is recommended to facilitate the removal of any caked deposits.
3. When DuPont™ DPX-121 is tank mixed with other pesticides, all cleanout procedures for each product should be
examined and the most rigorous procedure should be followed.
4. Follow any pre-cleanout guidelines recommended on other product labels.
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
The most effective drift management strategy is to apply the largest droplets which are consistent with pest control
objectives. 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.
A droplet size classification system describes the range of droplet sizes produced by spray nozzles. The American Society
of Agricultural and Biological Engineers (ASABE) provide a Standard that describes droplet size spectrum categories
defined by a number of reference nozzles (fine, coarse, etc.). Droplet spectra resulting from the use of a specific nozzle
may also be described in terms of volume mean diameter (VMD). Coarser droplet size spectra have larger VMD's and
lower drift potential
CONTROLLING DROPLET SIZE - GROUND APPLICATION
• Nozzle Type - Select a nozzle type that is designed for the intended application. With most nozzle types, narrower spray
angles produce larger droplets. The use of low-drift nozzles will reduce drift potential.
• Pressure - The lowest spray pressures recommended for the nozzle produce the largest droplets. Higher pressure reduces
droplet size and does not improve canopy penetration. When higher flow rates are needed, using a higher-capacity nozzle
instead of increasing pressure results in the coarsest droplet spectrum.
• Flow Rate/Orifice Size - Using the highest flow rate nozzles (largest orifice) that are consistent with pest control
objectives reduces the potential for spray drift. Nozzles with higher rated flows produce coarser droplet spectra.
CONTROLLING DROPLET SIZE - AIRCRAFT
• Nozzle Type - Solid stream, or other low drift nozzles produce the coarsest droplet spectra.
• Number of Nozzles - Using the minimum number of nozzles with the highest flow rate that provide uniform coverage
will produce a coarser droplet spectrum
• Nozzle Orientation - Orienting nozzles in a manner that minimizes the effects of air shear will produce the coarsest
droplet spectra. For some nozzles such as solid stream, pointing the nozzles straight back parallel to the airstream will
produce a coarser droplet spectrum than other orientations.
• Pressure - Selecting the pressure that produces the coarsest droplet spectrum for a particular nozzle and airspeed reduces
spray drift potential. For some nozzle types such as solid streams, lower pressures can produce finer droplet spectra and
increase drift potential
BOOM LENGTH (AIRCRAFT), AND APPLICATION HEIGHT , <, c c c c c c
Boom Length (aircraft) - Using shorter booms decreases drift potential. Boom lengths are expressed as a percentage of an
aircraft's wingspan or a helicopter's rotor blade diameter. Shorter boom length and proper positioriih£(c<in minimize drift
caused by wingtip or rotor vortices. L L i;c c ' ,. b ('. C O C C C C (.,
Application Height (aircraft) - Applications made at the lowest height that are consistent with pest control objectives pnd
the safe operation of the aircraft will reduce the potential for spray drift. cocci, c c o c
Application Height (ground) - Applications made at the lowest height consistent with pest controtebj&fctives, and that allow
the applicator to keep the boom level with the application site and minimize bounce, will reduce the exposure of spras^
droplets to evaporation and wind, and reduce spray drift potential. L
WIND L e c (.-
Drift potential is lowest when applications are made in light to gentle sustained winds (2-10 mph), which are blowing in a
constant direction. Many factors, including droplet size and equipment type also determine drift potential at any given
wind speed. AVOID GUSTY OR WINDLESS CONDITIONS.
Local terrain can also influence wind patterns. Every applicator is expected to be familiar with local wind patterns and how
they affect spray drift.
8

cTEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, set up equipment to produce larger droplets to reduce effects of
evaporation.
SURFACE TEMPERATURE INVERSIONS
Drift potential is high during a surface temperature inversion. Surface temperature inversions restrict vertical air mixing,
which may cause small suspended droplets to remain close to the ground and move laterally in a concentrated cloud.
Surface temperature inversions are characterized by increasing temperature with altitude and are common on nights with
limited cloud cover and light to ho wind. They begin to form as the sun sets and often continue into the morning. Mist or fog
may indicate the presence of an inversion in humid areas.
Inversions may also be identified by producing smoke and observing its behavior. Smoke that remains close to the ground, or
moves laterally in a concentrated cloud under low wind conditions indicates a surface inversion. Smoke that moves upward and
rapidly dissipates indicates good vertical air mixing.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the responsibility of the applicator to
verify that the shields are preventing drift and not interfering with uniform deposition of the product.
AIR-ASSISTED (AIR BLAST) FIELD CROP SPRAYERS
Air-assisted field crop sprayers carry droplets to the target via a downward-directed airstream. Some may reduce the potential
for drift, but if a sprayer is unsuitable for the application and/or set up improperly, high drift potential can result. It is the
responsibility of the applicator to determine that a sprayer is suitable for the intended application and is configured properly,
and that drift is not occurring.
SENSITIVE AREAS
Making applications when there is a sustained wind moving away from adjacent sensitive areas (e.g., residential areas, bodies
of water, known habitat for threatened or endangered species, non-target crops) is an effective way to minimize the effect of
spray drift.
DRIFT CONTROL ADDITIVIES
Using product compatible drift control additives can reduce drift potential. When a drift control additive is used, read and
carefully observe cautionary statements and allother information on the additive's label. If using an additive that increases
viscosity, ensure that the nozzles and other application equipment will function properly with a viscous spray solution.
Preferred drift control additives have been certified by the Chemical Producers and Distributors Association (CPDA).
INTEGRATED PEST MANAGEMENT
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.
RESISTANCE
DuPont™ DPX-121, which contains the active ingredients rimsulfuron and thifensulfuron -methyl, is a Group 2 herbicide
based on the mode of action classification system of the Weed Science Society of America.
When herbicides with mode of action classifications that affect the same biological sites of action are used repeatedly over
several years to control the same weed species in the same treatment area, naturally-occurring resistant biotypes may
survive a correctly applied herbicide treatment, propagate, and become dominant in that area. 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 biological site of action.
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 affect a different site of
action. Weed escapes that are allowed to go to seed, and movement of plant material between treatment areas on equipment
will promote the spread of resistant biotypes.
It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread
and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate state
agricultural extension service representative to determine appropriate actions for treating specific resistant weed biotypes in
your area. <-
