ENVIRONMENTAL HAZARDS
Groundwater Advisory: Chlorsulfuron and metsulfuron-methyl are known to leach through soil into
groundwater under certain conditions as a result of label use. This chemical may leach into groundwater if
used in areas where soils are permeable, particularly where the water table is shallow.
Surface Water Advisory: This product may impact surface water quality due to runoff of rain water. This
is especially true for poorly draining soils and soils with shallow ground water. This product is classified as
having high potential for reaching surface water vi a runoff for weeks after application. A level, well-
maintained vegetative buffer strip between areas to which this product is applied and surface water
features such as ponds, streams, and springs will reduce the potential loading of chlorsulfuron and
metsulfuron-methyl from runoff water and sediment. Runoff of this product will be greatly reduced by
avoiding applications when rainfall or irrigation is expected to occur within 48 hours.
Non-target Organism Advisory: This product is toxic to plants and may adversely impact the forage and
habitat of non-target organisms, in cluding pollinators, in areas adjace nt to the treated area. Protect the
forage and habitat of non-target organisms by minimizing spray drift. For further guidance and instructions
on how to minimize spray drift, refer to the Spray Drift Management section of this label.
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
Do not apply this product in a way that will contact wo rkers or other persons, either directly or through
drift. Only protected handlers may be in the area du ring application. For any requirements specific to
your State or Tribe, consult the agency responsible for pesticide regulation.
AGRICULTURAL USE REQUIREMENTS
Use this product only in accordance with its labeling and with the Worker Protection Standard 40 CFR
Part 170. This Standard contains requirements for the protection of agricultural workers on farms, forests,
nurseries, and greenhouses, and handlers of agricultur al pesticides. It contains requirements for training,
decontamination, notification, and emergency assistan ce. It also contains specific instructions and
exceptions pertaining to the statements on this la bel about personal protecti ve equipment (PPE), and

MANDATORY SPRAY DRIFT MANAGEMENT
Aerial Applications:
• Do not release spray at a height greater than 10 feet above the vegetative canopy, unless a greater
application height is necessary for pilot safety.
• For applications prior to the emergence of crops an d target weeds, applicators are required to use a
Coarse or coarser droplet size (ASABE S641).
• For all other applications, applic ators are required to use a Medium or coarser droplet size (ASABE
S641).
• The boom length must not exceed 65% of the wi ngspan for airplanes or 75% of the rotor blade
diameter for helicopters.
• Applicators must use ½ swath displacement upwind at the downwind edge of the field.
• Nozzles must be oriented so the spray is directed toward the back of the aircraft.
• Do not apply when wind speeds exceed 10 miles per hour at the application site.
• Do not apply during temperature inversions.
Ground Boom Applications:
• Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the
ground or crop canopy unless making a turf, pasture, or rangeland application, in which case
applicators may apply with a nozzle height no more than 4 feet above the ground.
• For applications prior to the emergence of crops an d target weeds, applicators are required to use a
Coarse or coarser droplet size (ASAE S572.3).
• For all other applications, applicators are requir ed to use a Medium or coarser droplet size ( ASAE
S572.3).
• Do not apply when wind speeds exceed 10 miles per hour at the application site.
• Do not apply during temperature inversions.
Boom-less Ground Applications:
• Applicators are required to use a Medium or coarser droplet size (ASAE S572.3) for all applications.
• Do not apply when wind speeds exceed 10 miles per hour at the application site.
• Do not apply during temperature inversions.
SPRAY DRIFT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF
NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
IMPORTANCE OF DROPLET SIZE
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide
target pest control. While applying larger droplets will reduce spray drift, the potential for drift will be
greater if applications are made improperly or under unfavorable environmental conditions.
Controlling Droplet Size Ground Boom
• Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use
the highest practical spray volume for the applicatio n. If a greater spray volume is needed, consider
using a nozzle with a higher flow rate.
• Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray
volume and droplet size.
• Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles
designed to reduce drift.
Controlling Droplet Size Aircraft
• Adjust Nozzles - Follow nozzle manufacturers recommendation s for setting up nozzles. Generally, to
reduce fine droplets, nozzles should be oriented parallel with the airflow in flight.
BOOM HEIGHT Ground Boom Use the lowest boom height that is compatible with the spray nozzles
5
that will provide uniform coverage. For ground equipm ent, the boom should remain level with the crop
and have minimal bounce.
RELEASE HEIGHT - Aircraft
Higher release heights increase the potential for spra y drift. When applying aerially to crops, do not
release spray at a height greater than 10 feet above the crop canopy, unless a greater application height
is necessary for pilot safety.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify
that the shields are not interfering with the uniform deposition of the spray on the target area.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.
TEMPERATURE INVERSIONS
Drift potential is high du ring a temperature inversion. Temperature inversions are characterized by
increasing temperature with altitude and are common on nights with limited cloud cover and light to no
wind. The presence of an inversion can be indicated by ground fog or 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 an inversion, while smoke that moves upward and rapidly
dissipates indicates good vertical air mixing. Avoid applications during temperature inversions.
WIND
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND
CONDITIONS.
Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.
Boom-less Ground Applications:
• Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.
Handheld Technology Applications:
• Take precautions to minimize spray drift.
ENVIRONMENTAL CONDITIONS AND ACTIVATION OF NUP-08136
NUP-08136 moves into plants by ab sorption through the roots and foliage and rapidly inhibits the growth
of susceptible weeds. Within one to three weeks af ter application, broadleaf weed growth slows, leaves
of susceptible plants become yellow to white in color, and growing points die. Within four to six weeks
after application, these effects are seen in annual weeds. Effects on perennial weeds and woody plants
are seen one season following the application.
For optimum preemergence control of target weeds, NUP-08136 needs to reach the weed roots.
Irrigationrainfall or sprinkler irrigation after an application (1-2 inches) moves the NUP-08136 into the
top few inches of the soil and into the weed root zone. As the amount of crop or weed residue increases
or if soils are fine in texture, an increased the amount of moisture is required for activation. When little or
no rainfall or irrigation is receiv ed after an application, weeds that germinate will not be controlled
because the NUP-08136 was not moved into the weed root zone by the moisture.
Optimum control of weeds shaded by rapidly growing crops or grasses is achieved with NUP-08136.
Ineffective control of weeds may be seen where grass stands are thin. If the canopy of the grasses
completely intercepts the spray solution, weed control will be reduced.
Under normal conditions, NUP-08136 will not harm desirable grasses. Injury to grasses may result from
application of NUP-08136 to grasses that are growing under stress (due to extreme temperatures or
moisture, abnormal soil conditions, or cultural practices) or to certain sensitive grass varieties.
6
Poor weed and brush control may be observed if rainfa ll, sprinkler irrigation, or snowfall occurs shortly
after application. Under cold, dry conditions moveme nt of NUP-08136 into the root zone of weeds and
brush will be delayed. NUP-08136 is less effective to weeds and brush hardened off by cold weather or
under stress from lack of water.
WEED RESISTANCE MANAGEMENT
For resistance management, this produc t contains two Group 2 herbicides chlorsulfuron and
metsulfuron-methyl. Any weed population may contain or develop plants naturally resistant to this product
and other Group 2 herbicides. The resistant biotyp es may dominate the weed population if these
herbicides are used repeatedly in the same field. Appropriate resistance mana gement strategies should
be 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 be come 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.
To delay herbicide resistance take one or more of the following steps:
• Rotate the use of this product or other Group 2 herbicides wi thin a growing season sequence or among
growing seasons with different herbicide groups that control the same weeds in a field.
• Use tank mixtures with herbicides from a different group if such use is permitted; where information on
resistance in target weed species is available, use the less resistance-prone partner at a rate that will
control the target weed(s) equally as well as the more resistance -prone partner. Consult your local
extension service or certified crop advisor if you are un sure as to which active ingredient is currently less
prone to resistance.
• Adopt an integrated weed -management program for herbicide use that includes scouting and uses
historical information related to herbicide use and cr op rotation, and that considers tillage ( or other
mechanical control methods), cultural ( e.g., higher crop seeding rates; precision fertilizer application
method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties)
and other management practices.
• Scout before and after herbicide application to monitor weed populations for early signs of resistance
development. Indicators of possible herbicide resistan ce include: (1) failure to control a weed species
normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent
weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) surviving plants
mixed with controlled individuals of the same specie s. If resistance is suspec ted, prevent weed seed
production in the affected area by an alternative he rbicide from a different group or by a mechanical
method such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning
harvesting and tillage equipment when moving between fields, and planting clean seed.
• If a weed pest population continues to progress after treatment with this product, discontinue use of this
product, and switch to another management strategy or herbicide with a different mode of action, if
available.
• Contact your local extension specialist or certifie d crop advisors for additional pesticide resistance -
management and/or integrated weed-management recommendations for specific crops and weed
biotypes.
• [For further information or to report suspected resistance, contact [Nufarm contact] at [one of][any of] the
following] [[[X]-XXX-XXX-XXXX] [[,][or]] 1-800-345-3330 [[,][or]] [Nufarm e-mail address] [][,][or]] [Nufarm
website] [[,][or]][XXXX]].]
It is advisable to keep accurate records of pesticides ap plied to individual fields to help obtain information
on the spread and dispersal of resistant biotypes. Contact your local sales representative, crop advisor, or
extension agent to find out if suspected resistant weeds to this MOA have been found in your region. Do
not assume that each listed weed is being controlled by this mechanisms of action. Co-formulated active
7
ingredients are intended to broaden the spectrum of weeds that are controlled. Some weeds may be
controlled by only one of the active ingredient in this product.
Suspected herbicide-resistant weeds may be identified by these indicators:
 Failure to control a weed species normally cont rolled by the herbicide at the dose applied,
especially if control is achieved on adjacent weeds;
 A spreading patch of non-controlled plants of a particular weed species; and
 Surviving plants mixed with controlled individuals of the same species.
INTEGRATED PEST MANAGEMENT
NUP-08136 may be used as part of an Integrated Pe st Management (IPM) program. This program relies
on tillage (or other mechanical), biological, cultural , and chemical control practices to prevent economic
pest damage. IPM principles and practices include field monitoring, historical information related to
herbicide use and crop rotation, correct identification of target pests, population monitoring, and treatment
when target pest populations reach a locally-deter mined action thresholds. Consult your state
cooperative extension service, prof essional consultants or other qualified authorities to determine the
action treatment threshold levels for treating specific pest/crop systems in your area.
WINDBLOWN SOIL PARTICLES
This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion
usually have a high silt and/or fine to very fine sand fractions and low or ganic matter content. Other
factors which can affects the movement of windblown soil include the intensity and direction of prevailing
winds, vegetative cover, site slope, rainfall, and drainage patterns. Avoid applying this product if
prevailing local conditions may be expected to result in off-site movement.
PASTURES, RANGELANDS AND GRASSES IN CRP
Use NUP-08136 on lands primarily dedicated to the pr oduction of pasture, rangeland, or established
grasses in the Conservation Reserve Program (CRP), and in uncultivated areas (fence rows, farmyards,
and rights-of-way) that are next to , or which transect or pass through, treated pastures, rangeland, or
CRP, where grazing or harvesting for animal feed of those uncultivated areas may occur.
NUP-08136 is a dispersible granule that is applied in water or in liquid nitrogen carriers for control or
suppression of broadleaf weeds and brush in past ure, rangeland and CRP. Apply NUP-08136 as a
uniform broadcast spray and always add a spray adjuvant unless otherwise specified on this label.
Although NUP-08136 is registered for use most states, check with your state extension or Department of
Agriculture before applying to be certain NUP-08136 is registered in your state. The use of NUP-08136 is
prohibited in these Colorado counties: Alamosa, Conejos, Costilla, Rio Grande, and Saguache.
Both preemergent and postemergent applications of NUP-08136 will control weeds. This control is
optimized when NUP-08136 is applied when weeds ar e young and actively growing. Several factors
(including use rate, weed growth stage and degree of infestation at the time of application, and post-
application weather conditions) will affect the range of weeds controlled and the length of residual activity.
Use of NUP-08136 is permitted in floodplains where su rface water is not present, in terrestrial areas of
deltas, and in low lying areas where water is drained bu t may be found in isolated pockets due to uneven
or unlevel conditions.

PRECAUTIONS AND RESTRICTIONS
Read the following restrictions and precautions to avoi d injury to or loss of desirable trees or other
desirable plants or vegetation. NUP -08136 will affect growing plants whose roots, stems or foliage come
in contact with NUP-08136. FOLLOW THE USE PRECAUTIONS ON THIS LABEL.
x To avoid severe injury or death, do not drain or flush equipment rinses on or near desirable trees or
other plants, on areas where their roots may extend, or in areas where the product may be washed or
moved into contact with desirable plant roots. Do not use this product on areas such as athletic fields,
commercial sod farms (including high-maintenance fine turfgrass areas), driveways, golf courses,
lawns, tennis courts, walks, or similar areas.
x Do not apply to grasses grown for seed.
x Do not contaminate irrigation ditches or water used for domestic purposes.
x Do not apply to irrigated land if the tail water will be used to irrigate crops.
x To avoid the possibility of surface runoff, do not apply to frozen ground or to snow-covered ground.
x Before using NUP-08136, consult your state experime nt station, university, or extension agent as to
sensitivity of grass species or varieties to various herbicides. If the sensitivity of the grass variety is
unknown, test NUP-08136 on a small area. Tolerance of grass seed mixtures to NUP-08136 varies
and the resulting stand may not reflect the seed ratio.
x NUP-08136 will discolor and/or cause injury to gras ses when certain conditions exist either before or
after the application, including heavy rainfall, high soil pH, extended cold weather, or wide fluctuations
in day/night temperatures. To avoid injury, do not apply NUP-08136 to grass growing under
conditions of stress as a result of severe weathe r conditions (such as drought, low fertility, water-
saturated soils, disease, or insect damage). Injury to grasses is possible if application is followed by
severe winter stress from drought, disease, or insect damage.
x To avoid injury to legumes, do not apply NUP-08136 to pastures, rangeland or CRP which are
undersown with legume crops. Severe injury or de ath may occur to legumes in seedling mixtures as
a result of NUP-08136 application.
x To minimize off-site movement of product on treated soils which can lead to damage of susceptible
crops, do not apply if soils are powdery, dry or ligh t, or sandy. Treated soil particles may move off-
site to non-target crop sites through wind or water. Low levels of NUP-08136 may injure or kill crops,
especially if crops are irrigated.
x Injury to agricultural crops may occur if runoff water from applications flows onto non-target
agricultural lands.
x Do not apply NUP-08136 under the following conditio ns: during heavy rainfall, if soils are water-
logged, if soils will not allow penetration of irrigation water which could result in off-site movement of
NUP-08136. Do not disturb treated soil to minimize off-site movement of NUP-08136 by soil erosion
due to wind or water.
x Weeds in wheel tracks may not be completely controll ed from ground applications if dry, dusty field
conditions exist.
x Maximum amount of chlorsulfuron per year: 1 ounce per acre.
x Maximum amount of metsulfuron-methyl per year: 1 ounce per acre.
x Leave treated areas undisturbed from cultivating or mowing for at least 7 days after application.

the surfactant.
x Delay application until later in th e spring when the new growth is 5 to 6 inches tall, or wait until the
fall.
x Seedhead suppression from NUP-08136 application ma y result in reduced yields in the first cutting.
Other Pasture and Rangeland Grasses Precautions: The sensitivity of grass species or varieties to
NUP-08136 may vary. If the sensitivity of the grass is unknown, test NUP-08136 on a small area. If the
grass is uninjured throughout the season, then larger areas may be treated the next season. Severe
injury and/or stunting of sensitive broadleaf spec ies (such as alfalfa and clover) will result from
applications of NUP-08136.
APPLICATION DIRECTIONS FOR CONSERVATION RESERVE PROGRAM (CRP)
Use NUP-08136 to control or suppress broadleaf weeds in established stands (pla nted previous year or
earlier) of the following perennial native or improved grasses grown on land enrolled in the Conservation
Reserve Program (CRP):
Blue Grama Indiangrass Sideoats grama
Bluestems (big, little, plains,
sand, WW spar)
Kleingrass Switchgrass (Blackwell)
Buffalograss Lovegrasses (atherstone,
sand, weeping, wilman)
Wheatgrasses (crested,
intermediate, pubescent,
slender, streambank, tall,
thickspike, western)
Green sprangletop Orchardgrass Wildrye grass- (Russian)
Satisfactory control by NUP-08136 may not be achi eved if newly planted CRP grass stands do not
sufficiently compete with weeds, or if weed pressure in CRP fields is severe. Follow up treatments such
as another herbicide application or mowing may be required.
Application Timing and Use Rates for CRP: Apply NUP-08136 postemergence at 0.125 to 0.25
ounces NUP-08136 per acre to the grasses list ed in the table above that were planted the
previous season and are fully tillered.
10
WEEDS AND BRUSH CONTROLLED OR SUPPRESSED IN PASTURES, RANGELAND OR CRP
Apply when weeds are no taller or wider in diameter than 4 inches and are actively growing (unless
specified otherwise in the Additional Directions for Specific Weeds section of this label). Before using
NUP-08136, carefully consider your crop rotation pl ans and options. Do not treat all acres (pasture,
rangeland, CRP) at the same time if rotational crop plant back flexibility is desired.

gg These weeds are suppressed and/or controlled. Evidence of suppression includes a visual reduction in numbers
of weeds as well as a significant loss of vigor. The extent that weeds are suppressed will depend on the use
rate, weed size at application and post-application environmental conditions.
ADDITIONAL DIRECTIONS FOR SPECIFIC WEEDS PASTURES, RANGELANDS AND CRP
Additional directions for certain weed species is list ed below. For optimum results, a thorough, uniform
spray is necessary to ensure coverage of all weeds.
Blue/Purple Mustard,
Flixweed, and
Tansymustard
For optimum results, apply NUP-08136 postemergence as a tank mix with another
herbicide (such as 2,4-D or MCPA which also controls these weeds). Apply prior to
bloom.
Broom Snakeweed For optimum results, apply 0.625 ounces per acre NUP-08136 in the fall. NUP-
08136 provides suppression only from spring applications.
Canada Thistle For suppression, time the application of NUP-08136, or NUP-08136 as a tank mix
with 2,4-D or MCPA, to occur in the spring after the majority of thistles emerge, are
small (rosette stage to 6” stems) and are actively growing. Emerged thistles treated
with NUP-08136 will be unable to compete with grass. Spot applications to fully-
leafed weeds, applied as a foliar spray, also suppress this weed.
Corn Gromwell, Cutleaf
Eveningprimrose and
Prostrate Knotweed
Time the application of NUP-08136, or NUP-08136 as a tank mix with 2,4-D or
MCPA, to occur when weeds are actively growing (2” or less in height) and when
thorough coverage of the spray onto the weeds through the grass canopy is ensured.
Kochia, Russian thistle,
Prickly lettuce
These weeds are known to have naturally occurring resistant biotypes which can be
best controlled from application of NUP -08136 in a tank mix with dicamba (such as
Banvel/Banvel SGF/Clarity) and/or 2, 4- D. Apply in the spring when weeds are
actively growing but 2” or less in height or 2” across. Refer to the Tank Mix section
for additional details.
Multiflora Rose Apply NUP-08136 as a broadcast application in the spring to multiflora rose that is
fully leafed and is no taller than 3 feet.
Musk Thistle, Scotch
Thistle
For optimum results, apply 0.25 ounces per acre NUP-08136 in the spring or early
summer before flowering, or in the fall (before soil becomes frozen) after newly
emerged plants are at the rosette growth stag e. Not all biotypes of musk and scotch
thistles will be controlled by NUP-08136. Additional information on use rates and tank
mixes for your area can be obtained from y our local Nufarm representative, dealer or
applicator.
Pensacola bahiagrass
control in established
Bermudag
rass pasture
For optimum results, apply 0.375 ounces NUP-08136 per acre. Apply in the spring
after greenup but prior to formation of bahiagrass seedhead. Make application only if
there is sufficient moisture to ensure growth of grass.
Bahiagrass can be successfully removed from Bermudagrass pastures using NUP-
08136. Use NUP
-08136 in areas with high Bahiagrass infestations to completely
clear the area of useful forage; the Bermudagrass will slowly recover. Make the
applications of NUP-08136 to different sections of an entire ranch or farm every year
and do not apply to the entire farm or ranch in one year since there will be no useful
forage available. To speed the reesta blishment of the Bermudagrass, fertilize
(particularly with nitrogen and potassium) and/or replant. Bahiagrass may regrow if
the bahiagrass infestation is severe, the treated areas are under grazing pressure, or
the weather conditions are not optimum. To avoid poor weed control and/or
reqrowth, do not apply NUP
-08136 in liquid fertilizer solutions for Pensacola
bahiagrass control.
Do not use NUP-08136 to control common or Argentine bahiagrass.
Plumeless Thistle For optimum results, apply 0.625 ounces NUP-08136 per acre. Apply in the early
spring or early summer. Weeds should be newly emerged and at the rosette growth
stage. If a fall application is made, do not apply if the soil becomes frozen.
Rush skeletonweed Apply 1.25 ounces NUP-08136 per acre in a tank mix with dicamba (8 fluid ounces of
products such as Banvel or Clarity per acre) and 2,4-D (16 fluid ounces per acre).
Sericea lespedeza For optimum results, apply 0.625 ounces NUP-08136 per acre from flower bud
initiation through the full bloom stage of growth. Delay applications if drought
conditions exist at the time of application.
Spotted Knapweed For optimum results, apply 0.625 ounces NUP-08136 per acre with dicamba (8 fluid
ounces of products such as Banvel or Clarity) and 2,4-D (16 fluid ounces per acre).
13
Snowberry (Western,
Common, Mountain)
Time applications of NUP-08136 (1.25 ounces per acre) to begin when plants are
actively growing continuing throughout the growing season up until fall defoliation.
Improved control is achieved with a tank mixture with 2,4 -D (ester formulation; refer
to Tank Mixtures section of this label for additional information).
Sunflower (wild or
volunteer)
Apply NUP-08136 as a tank mix with 2,4-D or MCPA by ground (in a minimum spray
volume of 10 gal per acre) or air (in a minimum spray volume of 3 gal per acre). Wait
until most of the sunflowers have emerged, are actively growing and are between 2
and 4 inches in height.
Wild Buckwheat Time application of NUP-08136 plus 2,4-D or MCPA to occur only when conditions
allow weeds to actively grow. Treat when plants have no more than 3 true leaves
(not counting the cotyledons).
Wild Garlic For optimum results, apply 0.125 to 0.25 ounces NUP-08136 per acre. Wild garlic is
best controlled in the early spring when plants are no taller than 12 inches and no
more than 2 to 4 inches of new growth.
Woolly Croton For optimum results, apply 0.125 to 0.25 ounces NUP-08136. Weeds are best
controlled in the late spring or early summer when plants are in the cotyledon through
2 true leaf stage.
Yucca For best results, apply 0.625 to 1 ounce NUP-08136. Tank mixes with 2,4-D,
dicamba, dicamba plus 2,4 -D, or Remedy ® provide additional control when applied
two weeks before bloom to two weeks post-bloom.
SPRAY ADJUVANTS PASTURES, RANGELANDS AND CRP
Always include a crop oil concentrate or nonionic su rfactant when applying NUP-08136 unless otherwise
directed. Your Nufarm representative can provide additional information if other adjuvant systems are
used. Only use adjuvants that are permitted for use with the combination herbicide products to be tank-
mixed with NUP-08136. Only product that are EPA- exempt (40 CFR 180) must be used. Additional
details can be found in the table below. Do not use low rates of liquid fertilizer as a substitute for
spray adjuvants.
Additive Instructions
Nonionic Surfactant (NIS) Apply at a rate (concentration) of 0.25 (1 qt. per 100 gal spray solution). If arid
conditions exist, apply at a rate of 0.5%. The surfactant must contain a
minimum of 60% nonionic surfactant that has a hydrophilic/lipophilic balance
(HLB) not less than 12.
Exceptions: On Fescue pastures, do not more than ½ to 1 pint non- ionic
surfactant per 100 gallons.
Crop Oil Concentrate (COC)
Petroleum or Modified Seed Oil
(MSO)
Apply at a rate of 1 gal. Per 100 gal. Of spray solution (1%) (use 2 gal per 100
gal spray solution if arid conditions exist). Use only oil adjuvants that have
80% high quality petroleum (mineral) or modified vegetable
-seed oil containing
at least 15% surfactant emulsifiers.
Special Types of Adjuvants To achieve required amounts of NIS, COS, MSO and/or ammonium nitrogen
fertilizer, use of a combination of adjuv ants are permitted as long as the use
rates and restrictions on the product labels are followed. Other specialty
adjuvants may be used providing they have similar functionality as the other
adjuvants listed on this label, and have been approved for use by Nufarm.
Consult Nufarm representatives prior to using adjuvants not specified on this
label.
Ammonium Nitrogen Fertilizer Apply at a rate of 2% (v/v). Use only high quality urea ammonium nitrates
(UANs; 28% N or 32% N). Another option is to apply no more than 17 lb per
acre of a sprayable ammonium sulfate (AMS).
Antifoaming agents Use these products if needed.
TANK MIXES WITH OTHER PRODUCTS PASTURES, RANGELANDS, AND CRP
Before making tank mix applications of NUP-08136 and other registered herbicides, insecticides,
fungicides, or liquid nitrogen fertil izers, read the table below for specific directions for tank mixes with
other products. Read and follow all manufacturers label reco mmendations for the tank mix partner. If
the recommendations conflict with this label, do not tank mix the product with NUP-08136. Before mixing
the tank mix product with NUP-08136, be sure all reco mmendations on the product labels do not conflict
with those on this label. Read the section Instructions for Preparing Tank Mixes of NUP-08136 ,
above, regarding preparation of pre-slurries of NUP-08136 before adding tank mix partners.
14
Tank-Mix Partner Application Directions
Insecticides or
Fungicides
Tank mixes of NUP-08136 with insecticides and fungicides registered for use on pastures,
rangelands or CRP are permitted as directed in the table below. NUP -08136 may also be
used sequentially with insecticides and fungicides on pastures, rangeland or CRP. Drought,
stress or cold weather may affect tank mixes or sequential applications of NUP
-08136 with
organophosphate insecticides (such as methyl parathion) producing temporary yellowing
and/or severe injury of grasses. These symptoms are most prevalent during periods when
day and night temperatures vary greatly immediately before or soon after the application.
Before large areas are treated, test NUP
-08136 in small test plots. Do not use NUP- 08136 in
tank mixes with 14alathion as this tank mix will result in grass injury.
Liquid Nitrogen
Fertilizers for CRP
Liquid nitrogen fertilizers (such as 28-0-0 or 32-0-0) may replace water as the carrier in spray
solutions. Check for physical compatibility before mixing NUP -08136 in liquid fertilizers.
Follow the directions in the sections Instructions for Preparing Tank Mixes of NUP- 08136
and Tank Mixes, especially regarding preparing a pre-slurry of NUP- 08136 with water before
adding the liquid nitrogen fertilizer. This tank -mix may cause temporary crop yellowing and
stunting.
Always add a non -ionic surfactant (1/4 pint per 100 gal spray solution; 0.03% v/v) when using
low rates of liquid nitrogen fertilizers (between 5% and 50% of spray solution by volume).
Only use non -ionic surfactants. The use of low rates of liquid fertilizers may not be used in
place of a spray adjuvant. Grass injury may result when liquid nitrogen fertilizer solutions are
greater than 5% of the spray solution by volume and the NUP
-08136 rate is more than 0.25
ounces,
Grass injury may occur if a surfactant is used when using higher rates of liquid nitrogen
fertilizers (greater than 50% of the spra y solution by volume). Obtain specific
recommendations from your agricultural dealer, consultant, or your Nufarm representative
prior to adding adjuvants to these tank mixes.
Do not use NUP-08136 with liquid fertilizers that have a pH of 3.0 or less.
When tank mixing NUP -08136 with 2,4-D or MCPA, the ester formulations are recommended
for increased compatibility. Increased chances of grass injury may occur when surfactants are
added to liquid fertilizer tank mixes of NUP -08136 plus 2,4- D ester or MCPA ester: do not
include a surfactant to these tank mixes when the liquid nitrogen fertilizer is greater than 5% of
the spray solution by volume.
Herbicides for
tank mixes in
Pasture or
Rangeland
Tank mixes of NUP-08136 with other registered herbicides may be applied to pasture and
rangelands to control or suppress weeds listed in the Weeds Controlled or Suppressed
table, weeds which are resistant to NUP -08136, or other weeds not listed on this label. Read
and follow all manufacturers label recommendations for the tank mix partner. Before mixing
the tank mix product with NUP
-08136, be sure all recommendations on the herbicide labels do
not conflict with those on this label. Refer to the other registered herbicide labels to confirm
that the product is labeled for control of the weeds listed above and is registered for use in
your state.
NUP-08136 can be applied in a tank mix with one of the following products.
8-32 oz. Grazon® P+D/A
4-16 oz. Tordon® 22/A

Preplant
Applications
Apply tank mixes of NUP-08136 and glyphosate (such as GLYFOS ® X-TRA or Roundup
UltraMax™) pre-plant (before planting CRP grasses) for control of broadleaf and grass weeds.
Do not plant grasses for at least 7 days after this NUP -08136 plus glyphosate tank mix
application. Read all product labeling and fact sheets for glyphosate before use.
15
Herbicides for
tank mixes in CRP
Postemergence
Applications
A tank mix of NUP-08136 plus 2,4-D (ester formulation is recommended) or dicamba (such as
Banvel or Clarity) will provide the best weed control performance in CRP,
Apply the tank mix of NUP-08136 using ¼ lb A.I. 2,4- D per Acre if labeled grasses exceed the
5-leaf stage. Use rates of ½ lb. A.I. 2,4- D per Acre when stands are fully tillered. Although
addition of a spray adjuvant is permitted, the chances for injury to grasses will increase.
Apply the tank mix of NUP-08136 using between 1/8 and ¼ lb A.I. dicamba per Acre if labeled
grasses exceed the 3 -leaf stage. Use rates of ¼ to ½ lb. A.I. dicamba per Acre when stands
are fully established (2 year stands). Although addition of a spray adjuvant is permitted, the
chances for injury to grasses will increase.

BROADLEAF WEED CONTROL IN WHEAT AND BARLEY
COLORADO, KANSAS, NEW MEXICO, OKLAHOMA AND TEXAS
NUP-08136 is a dispersible granule that is applied in water or in liquid nitrogen carriers for control or
suppression of broadleaf weeds in wheat and barley. Apply NUP-08136 as a uniform broadcast spray at
rates of 0.125 ounces per acre alone to control or suppress emerged broadleaf weeds postemergence, or
combine NUP-08136 with other herbicides registered for use on wheat and barl ey. Read and follow all
manufacturers label recommendations for the tank mix partner. Before mixing the tank mix product with
NUP-08136, be sure all recommendations on the herbicide labels do not conflict with those on this label.
Refer to the other registered herbicide labels to co nfirm that the product is labeled for control of the
weeds listed above and is registered for use in your state.
NUP-08136 is registered for use on wheat and barl ey only in the states of Colorado, Kansas, New
Mexico, Oklahoma and Texas.
Refer to the section below on Spray Adjuvants. Always include a nonionic surfactant, petroleum based
crop oil concentrate, or vegetable-seed oil-base d product (methylated seed oils are considered a
vegetable seed-based oil) in spray tanks unless othe rwise directed on this label. When applying NUP-
08136 with other herbicides, choose the adjuvants ba sed on the partner herbicide products limitations
regarding adjuvants.
APPLICATION DIRECTIONS FOR WHEAT AND BARLEY
Apply 0.125 ounces NUP-08136 per acre to wheat and barley to control or suppress broadleaf weeds that
are actively growing and are no more than 4 inches in height or in diameter. Crop injury may occur if
applications are made during boot and early heading. To prevent reduced weed control, do not apply if

ADDITIONAL DIRECTIONS FOR SPECIFIC WEEDS WHEAT AND BARLEY
Additional directions for certain weed species is list ed below. For optimum results, a thorough, uniform
spray is necessary to ensure coverage of all weeds.
Blue Mustard, Treacle
mustard, Flixweed, Small
seeded falseflax, and
Tansymustard
For optimum results, apply NUP-08136 postemergence to mustards as a tank mix
with another herbicide (such as 2,4-D or MCPA) which also controls these weeds.
Apply prior to bloom.
Tansy mustard, Flixweed, Treacle must ard and Small seeded falseflax : use 0.1
ounce NUP-08136 plus ¼ pound A.I. 2,4-D ester for control of these weeds.
Tansy mustard, Flixweed or Treacle mustard only: use 0.083 ounces NUP-08136
plus ¼ pound active 2,4-D ester for control of these weeds.
Canada Thistle and
Sowthistle:
Apply in the spring using NUP-08136 plus surfactant or NUP-08136 plus 2,4-D or
MCPA. Time applications to occur after most of the thistles have emerged, are small
(rosette stage to 6” stems) and are actively growing. Emerged thistles treated with
NUP-08136 will be unable to compete with the crop.
Corn gromwell and
Prostrate knotweed:
Time the application of NUP-08136 plus su rfactant to occur when weeds are actively
growing (2” or less in height) and when thorough coverage of the spray onto the
weeds through the grass canopy is ensured. Results may be improved using a tank
mix of NUP
-08136 plus 2,4-D or MCPA.
Kochia, Russian thistle,
Prickly lettuce
These weeds are known to have naturally occurring resistant biotypes which can be
best controlled from application of NUP -08136 in a tank mix with dicamba plus 2, 4-
D, or with bromoxynil plus 2,4 -D. Apply in the spring when weeds are actively
growing but 2” or less in height or diameter. Refer to the Tank Mix section for
additional details.
Sunflower
(common/volunteer):
Apply NUP-08136 plus surfactant or NUP-08136 as a tank mix with 2,4-D or MCPA
by ground (in a minimum spray volume of 10 gal per acre) or air (in a minimum spray
volume of 3 gal per acre). Wait until most of the sunflowers have emerged, are
actively growing and are between 2 and 4 inches in height.
Wild buckwheat Time application of NUP-08136 plus 2,4-D or MCPA to occur only when conditions
allow weeds to actively grow. Treat when plants have no more than 3 true leaves
(not counting the cotyledons).
SPRAY ADJUVANTS Nonionic Surfactant (NIS) WHEAT AND BARLEY
Always include a nonionic surfactant, petroleum based crop oil concentrate, or vegetable-seed oil-based
product (methylated seed oils are considered a vegetable seed-based oil) in spray tanks unless otherwise
directed on this label. When applying NUP-08136 with other herbicides, choose the adjuvants based on
the partner herbicide products limitations regarding adjuvants. Additional details can be found in the table
below.
Additive Instructions
Nonionic Surfactant (NIS) Apply at a rate (concentration) of 0.25-0.5% v/v (1-2 qt. per 100 gal spray
solution). If hot and arid conditions exist, apply at a rate of 0.5%.
Crop Oil Concentrate (COC)
Petroleum or Modified Seed Oil
(MSO)
Replace the NIS with a COC if desired when arid conditions or cool weather
conditions exist. Apply at a rate of 1 -2 gal. Per 100 gal. Of spray solution (1-
2% v/v). Use only petroleum based COCs that have 80% high quality
petroleum (mineral) or modified vegetable -seed oil containing at least 15%
surfactant/emulsifiers.
18
Ammonium Nitrogen Fertilizer To enhance weed control, add an ammonium nitrogen fertilizer to the
surfactant or COC. Another option is to use a high quality, sprayable grade of
ammonium sulfate (AMS; 21-0-0).
GROUND APPLICATION PASTURES, RANGELANDS, CRP, WHEAT AND BARLEY
The use of flat-fan or low-volume flood nozzles will provide optimum spray distribution and thorough
coverage of spray solution. Use the following spray volumes for the type of nozzle selected:
x flat-fan nozzles minimum 10 gal. Per Acre (GPA) broadcast;
x flood jet on 30 inch spacings minimum 10 GPA (flood nozzles are TK10, or equivalent with a
minimum of 30 psi);
x flood jet on 40 inch spacings minimum 13 GPA;
x flood jet on 60-inch spacings minimum 20 GPA.
It is essential to overlap the nozzles 100% for all sp acings. Use Raindrop RA nozzles with at least 30
GPA and ensure that nozzle spray patterns overlap 100%. Screens must be 50-mesh or larger.
AERIAL APPLICATION PASTURES, RANGELANDS, CRP, WHEAT AND BARLEY
Apply NUP-08136 in a minimum of 3 gallons per Acre using spray nozzle types and arrangements that
optimizes spray distribution and provides maximum coverage.
To prevent drift into adjacent areas or onto sensit ive crops, apply NUP-08136 by air using solid stream
nozzles oriented straight back. To minimize spray drift, supplement aerial applications of NUP-08136 with
ground applications to borders and edges of fiel ds. See additional precautions in the section Spray Drift
Management.
DIRECTIONS FOR CROP ROTATION PASTURES, RANGELANDS, CRP, WHEAT AND BARLEY
Do not treat all acres (pasture, range, CRP, wheat or barley) at the same time with NUP-08136 if
rotational crop plant back flexibility is desired. Before using NUP-08136, plan your application and
rotation crop strategy.
Follow the rotation crop intervals specified in the tables below. Minimum rotation crop intervals are
defined as the amount of time that must elapse from the last application to the anticipated date of the next
planting. These intervals have been established based on how quickly NUP-08136 breaks down in the
soil. Factors that influence the rate of breakdown include soil pH, soil temperature, soil microbes, and soil
moisture. Soils that have a low pH (less than 7.0), high moisture (regions that receive over 20” of annual
rainfall), and high soil temperatures (greater than 40° F) facilitate the breakdown of NUP-08136 in soil.
Conversely, soils with high soil pH, low moisture an d low soil temperatures tend to break down NUP-
08136 more slowly. Because soil temperatures and soil moisture can vary from season to season,
monitor this information when considering crop rotations.
SOIL PH LIMITATIONS: If soils have a pH above 7.9, do not apply NUP-08136 to these fields or
residues of NUP-08136 may persist for 34 months or longer. This residual activity may require crop
rotation intervals longer than the timi ng listed in the table below in order to avoid injury to sensitive crops
(wheat, barley and other sensitive crops) or grasses.
Testing Soil pH: Do not apply NUP-08136 until you have test ed the soil pH in areas where treatment is
planned. To determine the pH of the soil, sample soils taken from different, representative areas at
depths of between 0 and 4 inches. Send the samples to a laboratory for individual pH determinations.
Additional information on soil sampling can be obtained from local extension publications.
BIOASSAY: Before planting crops (other than wheat, barley) or grass species/varieties not listed in the
table for Rotation Crop Intervals into areas previously treated with NUP-08136, a field bioassay test is
required. A bioassay is also needed if the soil pH is outside the specified range or use rate is not listed in
the table. Test the crop(s) or grass(es) intended to be planted the year following a treatment with NUP-
08136 by growing the crop in small plots which received the NUP-08136 treatment. The crop or grass
response will determine the feasibility of rotating this crop or grass to large areas which had been treated
19
with NUP-08136. Additional information on the procedures for carrying out field bioassays can be
obtained from your local dealer or Nufarm representative.

GRAZING RESTRICTIONS PASTURES, RANGELANDS, CRP, WHEAT AND BARLEY
There are no grazing restrictions when using NUP-08136 on range, past ure, CRP or other uncultivated
areas (fence rows, farmyards, and ri ghts-of-way) that are next to, or which transect or pass through,
treated areas. There are no grazing restrictions when using NUP-08136 in wheat and barley.
HARVESTING OF HAY PASTURES, RANGELANDS, CRP, WHEAT AND BARLEY
There are no restrictions on harves ting hay when NUP-08136 is applied to wheat, barley, range, pasture,
CRP, and/or undesirable vegetation in uncultivated areas (fence rows, farmyards, and rights-of-way)
which are adjacent to, or pass through or transect, tr eated areas. Wear coveralls and shoes plus socks if
cutting occurs within 4 hours of treatment.
INSTRUCTIONS FOR PREPARING TANK MIXES OF NUP-08136
1. Using clean fresh water, fill the spray tank ¼ to 1/3 full. If a liquid nitrogen fertilizer solution is used in
place of water, refer to the Tank Mixtures section for additional details.
2. Begin agitation and then add the required amount of NU-08136.
3. Allow the solution to agitate for 5 minutes to completely disperse the NU-08136.
4. Continue agitation and fill the spray tank with th e remaining water. Do no t add any other material
until the NU-08136 is thoroughly mixed with the water.
5. As the tank is filling with the remaining amount of water, add any tank mix partners followed by the
necessary volume of spray adjuvant. Always add th e spray adjuvant last. Do not mix NU-08136 with
spray additives that reduce the pH of the spray solution below 3.0.
6. NOTE: Continuous agitation is required or settling will occur. Before spraying, reagitate the solution
to ensure a uniform solution is sprayed.
7. Make only a sufficient amount of NU-08136 spray mi xture that can be used within 24 hours of mixing.
The product may degrade if allowed to sit unused.
8. For application of multiple loads of NU-08136 and a tank mix partner, make a pre-slurry of NUP-
08136 in clean water and then add to the spray tank. This pre-mix helps to prevent the tank mix
partner from interfering with the dissolution of the NUP-08136.
23
SPRAY EQUIPMENT FOR APPLICATION OF NUP-08136
Refer to the manufacturers recommendations for addi tional information on GPA, pressure, speed, nozzle
types and arrangements, nozzle heights above the targ et canopy, etc. Use calibrated air or ground
equipment and apply using a spray volume and delivery system to ensure a thorough, uniform spray
coverage of weed pests. Use precautions to minimi ze drift. Higher spray volumes will produce better
coverage to dense canopies of weeds. Do not overlap sprays. To avoid injury to desirable species, turn
off spray booms while starting, turning, slowing, or stopping. Do not make ap plications using equipment
and/or spray volumes or under weather conditions th at might cause spray drift onto nontarget sites.
Additional information is provided in the section on Spray Drift Management. Use application equipment
that will ensure constant agitation of NUP-08136 spray solutions.
HOW TO CLEAN SPRAYER EQUIPMENT
Clean all spray equipment before making an applicatio n of NUP-08136. Immediately after an application
or multiple applications of NUP-08136, clean all spray equipment using the cleanup procedures described
on the labels of previously applied products. If ther e are no cleanup directions, use the following cleanup
procedures. After spraying is completed at the end of the day, rinse the interior of the tank with fresh
water. Partially refill the tank with fresh water and flush the boom and hoses. These rinses will prevent
deposits of dried pesticide residues that can remain in the application equipment.
Residues of NUP-08136 that remain in the spray equi pment may injure desirable crops if the equipment
is used to make applications to crops other than wheat, barley, pasture, rangeland or CRP. Use the
following steps to clean all mixing and spray equipment immediately following applications of NUP-08136:
1. Drain the spray tank and then use fresh water to rinse the interior surfaces of the tank. Then
flush the tank, boom, and hoses with water for at least 5 minutes. Physically remove any solid
deposits that are found around the equipment.
2. Use fresh clean water to fill the tank and add one gallon of household ammonia (3%)
† per 100
gallons of water. Flush the boom, hoses, and nozzles with this cleaning solution. Completely fill
the tank with fresh water and circulate the solution through the tank and hoses for 15 minutes.
Flush the boom, hoses, and nozzles, and then drain the tank.
3. Remove and clean the nozzles and screens separately. Use a bucket filled with the cleaning
solution.
4. Repeat step 2.
5. Use clean water to rinse the tank, boom and hoses.
6. If the cleaner used is only ammonia, the rinsate solution may be discarded by being applied to the
crop(s) recommended on this label. Do not exceed the maximum labeled use rate. If other
cleaners are used, consult the cleaner label for rinsate disposal instructions. If no instructions are
given, dispose of the rinsate on-site or at an approved waste disposal facility.
† Other Nufarm-approved cleaning solutions or different stre ngths of ammonia solution can also be used
as cleaning agents. Use the same amounts as noted in step 2, above. Carefully follow the directions for
use on the labels of the individual cleaner. Consul t your Agricultural dealer, applicator, or Nufarm
representative for a listing of approved cleaners.
Notes for Sprayer Equipment Cleaning:
x Do not use chlorine bleach with ammonia as dang erous gases will form. Clean equipment in well-
ventilated areas.
x Before following the above cleanout procedure for ae rial spray tanks, steam-clean the tanks to aid in
removing caked deposits.
x Follow the most rigorous cleanout procedure for all pesticides which are tank-mixed with NUP-08136.
x After completing the above cleanout procedure an d before using the sprayer equipment to make the
next pesticide application, clean out the sprayer fo llowing the procedures on the pesticide product label
that will be applied.
x It is recommended that a dedicated sprayer be ke pt for NUP-08136 applications during the growing
season. Dedicated equipment for NUP-08136 applications will help to minimize the potential for injury
to NUP-08136-sensitive crops if routine sprayi ng practices include equipment shared between
applications of NUP-08136 and applications of other pesticides during the same spray season.
