This product is conditionally registered in accordance with
FIFRA sec. 3(c) (7) (A) provided that you:
1. Submit and/or cite all data required f'ororegistration of
your product under FIFRA sec. 3(c) (5) when the Agency requires all
registrants of similar products to submit such data; and submit
acceptable_responses required for reregistration of yourprcduct
under FIFR~ section 4.
2. Make the following label changes:
a. Revise the EPA Registration Number to read, "EPA Reg.
No. 33270-8".
b. On page 13, under the heading "Application Methods",
you must include the following spray drift language on
your product labeling:
E:PA :o!:':n a57~-6
"Avoiding spray drift at the application is the
responsibility of the applicator. The interaction of
many equipment-and-weather-related factors determined
the potential 'for spray drift. The applicator and the
grower are responsible for considering all these
factors when making decisions."

page 2
EPA Reg. No. 33270-8
In the same section as mentioned above, please
incorportate the Lollowing spray drift mangement
practices and the aerial drift reduction advisory
information to avoid off-target drift movement from
aerial applications on your product labeling:
"The distance from the outer most nozzles on the boom
must not exceed·3/4 the length of the wingspan or rotor."
"Nozzles must always point backword parallel with the
air stream and never be pointed downwards more than 45
degrees."
"Aerial Drift Reduction Advisory Information"
Infor.mation on Droplet Size
The most effective way to reduce drift potential is to
apply large droplets. The best drift strategy is to
management strategy to apply the large~t droplets that
provide sufficient coverage and control. Applying
larger droplets reduces drift potential, but will not
prevent drift if applications are made improperly, or
under unfavorable environmental conditions (see Wind,
Temperature and Humidity, and Temperature Inversions) .
Controlling Droplet Size
Volume - Use 3 high flow rate nozzles to apply the
highest practical spray volume. Nozzles with-higher rated
flows produce larger droplets.
Pressure - Do not exceed the nozzle manufacturer's
recommended pressures. For may nozzle types iower
pressure produced larger droplets. When higher flow rates
are needed, use higher flow rate nozzles instead-of
increasing pressure.
Number of noz~les - Use the minimum number of nozzles that
provide uniform coverage.
Nozzle Orientation - Orienting nozzles so that the spray is
released parallel to the airstream produces larger droplets
than other orientations and is the recommended praqtice.
Significant deflection from horizontal will reduce droplet
size and increase drift potential.
Nozzle Type -Use nozzle type that is designed for the
intended application. With most nozzle types, narrow
stray angles produce larger droplets. ,Consider using
low-drift nozzles. Solid stream nozzles oriented
straight back produce the largest.droplets and the
lowest drift.
Boom Length

(
page 3
EPA Reg. No. 33270-8
For some use patterns, reducing the effective boom
length to less than 3/4 of the wingspan or rotor
length may further reduce drift without reducing swath
width.
Application Height
Applications should not be made at a height greater
than 10 feet above the top of the largest plants
unless a greater height is required for. aircraft
safety. Making applications at the lowest height
that is safe reduces exposure of droplets to
evaporation and wind.
Swath Adjustment
When applications are made with a crosswind, the
swath will be displaced downward. Therefore, on
the up and downwind edges of the field, the
applicator must compensate for this displacement by
adjusting the path of the aircraft upwind. Swath
adjustment distance should increased, with
increasing drift potential (higher wind, smaller
drops, etc).
Wind
Drift potential is lowest between wind speeds of 2-
10 mph. However, many factors, including droplet
size ana equipment type determine drift potential
at any given speed. Application should be avoided
below 2 mph due to variable wind direction and high
inversion potential. NOTE: Local terrain can
influence wind patterns. Every applicator should
be familiar with local wind pat~erns and how they
affect spray drift.
Temperature and Humidity
When making applications in low relative humidity,
set up equipment to produce larger droplets to
compensate for evaporation. Droplet evaporation
is most severe when conditions are both hot and dry.
Temperature Inversions
Applications should not occur during a temperature
inversion because drift potential is high. Temperature
inversions restrict vertical air mixing, which causes small
suspended droplets to remain in a concentrated cloud. This
cloud can move in unpredictable directions due to the light
variable winds common during inversions. Temperature
inversions are characterized by increasing temperatures
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

page 4
EPA Reg. No. 33270--'8
can be indicated by ground fog; however, if fog is riot
present, inversions can also be identified by the
movement of smoke from a ground source-: or andaircraf::
smoke generator. Smoke thac. layers and moVes laterall".' in
a concentrated cloud (under low wind conditions)
indicates an inversion, while smoke that moves upward and
rapidly dissipates indicates goed vertical air mixing.
Sensitive Areas
The pesticide should only be applied wbenthe potential for
drift to adjacent sensitiVe areas (e.g, residential areas,
bodies of water; cknown habitat for threatened or endan~ered
species, non-target crops) is minimal (e.g. when wind id
blowing away from the sensitive areas)."
c. On pages 2 and 8, under the heading "Environmental Hazards",
you must delete the followi~g sentence:
"This pesticide is toxic to fis!:." Please incorporate t!::te
following sentence: "This pesticide is:extremely toxic::o
freshwater marine, and estu:::-arir:e fish and aquatic
invertebrates including shrimp a:J.doyster."
d. On page 14, under the headi:J.g "General Chemigation
Directions", there is a tYF:Jgra];:hical error in the firs::
paragraph. Please insert a comrr:a" between "lateral mO\;~"
and "end tow".
3. Submit two copies of the revised final printed label f:J:::- the
record.
If these conditions are not corr-plied with, the regist::::a::ion
will be subject to cancellation in acco:::-dance with FIFRA sec. 6(e).
Your release for shipment of the product constitutes accepta::ce of
these conditions.

/ General Information
/ US Sentry Trifluralin is a selective herbicide for the preemergence control of annual grasses and
broadleaf weeds. US Sentry Trifluralin may be applied in liquid sprays of water or liquid fertilizer,
or impregnated on dry bulk fertilizer. To reduce loss of herbicidal activity, US Sentry Trifluralin
should be soil incorporated within 24 hours after application unless otherwise specified in specific
use directions or supplemental labeling. US Sentry TrifluraJin may be tank mixed or followed by
overlay or postemergence treatments with other herbicides to improve the spectrum of weeds
controlled. US Sentry TrifJuralin controls weeds by disrupting growth processes during
germination. US Sentry Trifluralin does not control established weeds.

US Sentry TrifluralinJdraftl09-18197 Page 10
/General Use Precautions
Applied according to directions and under normal growing conditions, US Sentry Trifluralin will not
harm the treated crop. Over-application may resuH in crop injury or rotational crop damage from
herbicide carryover. Uneven application or improper incorporation of US Sentry Trifluralin can
result in erratic weed control or crop injury. Seedling disease, cold weather, deep planting,
excessive moisture, high salt concentration, or drought may weaken crop seedlings and increase
the possibility of damage from US Sentry Trifluralin .. Under these conditions, delayed crop
development or reduced yields may resuH.
Do not apply US Sentry Trifluralin to soils that are wet or are subject to prolonged periods of
flooding as poor weed control may resutt
Do not use US Sentry Trifluralin on any crop grown in Pecos county or Reeves county, Texas.
In Montana, uses of US Sentry Trifluralin are limited to those described in supplemental labeling.
Refer to supplemental labeling for crops and specific use directions.
Chemigation: US Sentry Trifluralin may be appli€d by chemigation on certain crops. See
instructions for chemigation in the "Application Methods" section of this label. Also, see specific
instructions for certain crops in the "Approved Crops' section of this label.

during early growth stages may increase the possibility of crop injury.
All other areas receiving more than 20 inches of rainfall and irrigation: Unless crop injury is
acceptable, do not plant proso millet, sorghum (milo), oats, and annual or perennial grass crops or
grass mixtures for 12 months after a spring application or 14 months after a fall application of US
Sentry Trifluralin.
Other Crops
Vegetable crops, other than those to which US Sentry Trifluralin may be applied as a preplant soil
incorporated treatment, should not be planted within 5 months after an application of US Sentry
Trifluralin.
/SOil Texture Guide for Application Rates
Rate recommendations for incorporated treatments of US Sentry Trifluralin are based on "Soil
Texture Class· (coarse, medium, or fine) and soil organic matter content. A fine textured soil
(e.g., clay loam) will require a higher application rate than a coarse textured soil (e.g., loamy
sand). In the table below, find the 'Soil Texture Class" (coarse, medium, or fine) corresponding to
the "Soil Texture to be Treated". Choose the proper rate for each application based on the 'Soil
Texture Class" and specific crop recommendations. Do not exceed recommended rates.
Soil Texture Class Soil Texture to be Treated
Coarse (Light) Soils Sand, loam1 sand, sanl:!Y loam
Medium Soils Loam, silty clay loamt , silt loam, silt, sandy
clay loamt
Fine (Heavy) Soils Clay, clay loam, silty clay loamt , silty clay,
sandy clay, sandy clay loamt
tSiity clay loam and sandy clay loam soils are transitional soils and may be classified as either
medium or fine textured soils. If silty clay loam or sandy clay loam soils are predominantly sand
or silt, they are usually classified as medium textured soils. If they are predominantly clay, they
are usually classified as fine textured soils.
I Mixing Directions
us Sentry Trifluralin - Alone
US Sentry Tritluralin may be mixed with water or most liquid fertilizer materials. Prior to mixing US
Sentry Trifluralin in liquid fertilizE!l'", refer to the label section entitled "Testing for Compatibility in
Liquid Fertilizers' for testing procedures to determine compatibility with the liquid fertilizer product
to be used. The combination of US Sentry Trifluralin with solution and suspension-type fertilizers
provides weed and grass control equal to water sprays.
Fill spray tank 1/3 to 1/2 full with clean water or liquid fertilizer. Start agitation. Add correct
amount of US Sentry Trifluralin and continue agitation while filling tank to required spray volume.
Precaution: Do not allow water or spray mixture to back-siphon into a water source.
US Sentry Trifluralin in Tank Mix
For broader spectrum weed control, US Sentry Trifluralin may be applied in tank mix combination
with other products registered for use on crops listed in this label unless tank mixing with Treflan
(trifluralin) is prohibited by the manufacturer's label. When tank mixing, use the recommended
rate of US Sentry Trifluralin. Follow the label "Directions for Use" of each tank mix partner for
applicable use instructions including application rate, application timing, weeds controlled, and
specific precautions and restrictions of product use.

US Sentry TrifluralinldrafV09·18/97
US Sentry Trifluralin may be tank mixed with other products and applied with water or most liquid
fertilizer materials. Prior to mixing tank mixes containing US Sentry Trifluralin with liquid fertilizer,
refer to label section entitled "Testing for Compatibility in Liquid Fertilizers" for testing procedures
to determine tank mix compatibility with the liquid fertilizer product to be used.
Vigorous, continuous agitation during mixing, filling, and throughout application is required for all
tank mixes. Sparger pipe agitators generally provide the most effective agitation in spray tanks.
To prevent foaming in the spray tank, avoid stirring or splashing air into the spray mixture. To
prevent foaming during filling, keep end of fill pipe below the surface of the liquid in the spray tank.
Mixing Order: Fill the spray tank to 1/4 to 1/3 of the total spray volume required. Start agitation.
Add different formulation types in the order indicated below, allowing time for complete mixing and
dispersion after addition of each product. Allow extra mixing and dispersion time for dry flowable
products.
Add different formulation types in the following order: Dry flowables (OF); wettable powders 0NP);
aqueous suspensions (AS), flowables (F) and liquids (L).
Maintain agitation and fill spray tank to 3/4 of total spray volume. Add US Sentry Trifluralin and
other emulsifiable concentrates (EC) and any solutions (S).
Finish filling the spray tank. Maintain continuous agitation during mixing, final filling. and
throughout application. If spraying/agitation must be stopped before the spray tank is empty. the
materials may settle to the bottom. Settled materials must be resuspended before spraying is
resumed. A sparger agitator is particularly useful for this purpose. Settled material may be more
difficult to resuspend than when originally mixed.
Precautions:
Read and carefully follow all label instructions for each material added to the spray tank.
Do not allow water or spray mixture to back-siphon into a water source.
Premixing: Dry and flowable formulations may be premixed with water (slurried) and added to
the spray tank through a 20 to 35 mesh screen. This procedure assures good initial dispersion of
these products in liquid fertilizer or water.
Lint? screens in the spray tank should be no finer than 50 mesh (100 mesh is finer than 50 mesh).
/ Testing for Compatibility in Liquid Fertilizers
US Sentry Trifluralin alone or in tank mix combination with dry flowables (OF). wettable powders
(WP), aqueous suspensions (AS), flowables (F), liquids (L), or solutions (S) may not combine
properly with some liquid fertilizer materials. Small quantities should always be tested before full
scale mixing. Follow the testing procedure below to determine if a compatibility agent is needed.
If required, use only a phosphate esler-type surfactant designed for use with liquid fertilizers.
Such compatibility agents can be mixed at rates as low as 1.5 to 2.0 pints per ton of liquid
fertilizer. Add the compatibility agent just before adding pesticides.
Testing Procedure
1. Add 1 pint of the liquid fertilizer to a quart jar.
2. Add 1 to 4 teaspoons of the OF, WP, AS, F, or L formulation (depending on mixing ratio
required) to the liquid fertilizer. Close the jar and agitate until the materials are evenly
dispersed in the liquid fertilizer. If the materials do not disperse well, it may be necessary to
slurry the chemicals in water before adding to the fertilizer.
3. After dispersing the materials (step 2) add 3 to 4 teaspoons of US Sentry Trifluralin and other
EC formulations to the jar and shake well. Add solution herbicides to the mixture last and
agitate. Observe the jar for about 10 minutes. If materials rise to the surface and form a thick
layer (oily curds) that will not redisperse when agitated, a compatibility agent is needed. If the

US Sentry Trifluralinldraftl09·18/97 Page 13
mixture is easily redispersed with slight agitation, a compatibility agent is not required. Good
agitation, however, must be provided to maintain dispersion in the spray tank.
4. If the need for a compatibility agent is demonstrated (step 3) the following procedure is
recommended: Using a clean quart jar repeat step 1 above and add 1/2 teaspoon of the
compatibility agent to the liquid fertilizer. Mix well and then repeat steps 2 and 3.
An effective compatibility agent will cause the mixture to remain uniformly dispersed with little or
no separation (oil rising to the surface) for 1/2 hour or longer. If slight separation occurs, 2 to 3
inversions of the jar should be sufficient to uniformly redisperse the mixture. If oily curds form and
will not redisperse, additional compatibility agent or an alternative compatibility agent should be
tried.
Use a clean jar for each test. A compatible mixture will have a uniform appearance and will be
relatively easy to redisperse with gentle agitation of the jar.
Note: Compliance with state regulations for liquid fertilizer mixing, registration, labeling, and
application are the responsibility of the individual andlor company offering the fertilizer or chemical
mixture for sale.
/ Application Methods
General
As spray volume decreases, the importance of accurate calibration and uniform application
increases. Check calibration and uniformity of spray application daily. To avoid spray drift, do not
apply when winds are gusting or when wind speed is greater than 15 mph.
Ground Broadcast Application
Apply US Sentry Trifluralin in 5 to 40 gallons of liquid carrier per acre (broadcast basis), using any
properly calibrated, low pressure herbicide sprayer that will apply the spray uniformly. The carrier
may be water or liquid fertilizer as specified for the crop to be treated in the "Approved Crops"
section of this label. For band application, adjust herbicide rate and spray volume in proportion to
the band width and row width treated.
Aerial Broadcast Application
Apply US Sentry Trifluralin in 5 to 10 gallons of water per acre. Adjust pump pressure, nozzle
arrangements, speed, and application height to provide uniform application to the soil surface.
Use swath markers or flaggers to assure proper swath width interval.
Application with Dry Bulk Fertilizer
Dry bulk fertilizers impregnated or coated with US Sentry Trifluralin may be applied as a preplant
incorporated treatment on approved crops. All label recommendations for US Sentry Trifluralin
regarding application rates, incorporation directions, special instructions, and precautions should
be followed. Read and follow alllab~1 instructions below concerning use of US Sentry Trifluralin
with dry bulk fertilizer. Properly applied dry bulk fertilizers impregnated with US Sentry Trifluralin
provides weed and grass control equal to water sprays.
Use the following formula to calculate the amount of US Sentry Trifluralin required to impregnate a
ton of dry bulk fertilizer.

limestone. These materials will not absorb the herbicide. Blends containing mixtures of these
materials can be impregnated.
Impregnation: Use any closed drum, belt, ribbon, or other commonly used dry bulk fertilizer
blender. Nozzles used to apply US Sentry Trifluralin to dry bulk fertilizer should be placed to
provide uniform spray coverage.
Application and Incorporation: Spread the fertilizer/chemical mixture with properly calibrated
application equipment. Be certain the material is applied uniformly to the soil surface. Dry bulk
fertilizer impregnated with US Sentry Trifluralin must be incorporated 2 times. The first
incorporation should occur within 24 hours after application. The second incorporation should be
delayed a minimum of 5 days after the first and be completed prior to planting.
Compliance with State Regulations: Compliance with state regulations relating to dry bulk
fertilizer blending, registration, labeling, and application are the responsibility of the individual
and/or company offering the fertilizer or chemical mixture for sale.
Application by Chemigation
US Sentry Trifluralin may be applied through properly equipped chemigation systems for weed
control in certain crops as specified in "Approved Crops· section of this label. Read and follow all
label instructions outlined below concerning chemigation before applying US Sentry Trifluralin by
this method.
General Chemigation Directions:
Apply this product only through continuously moving center pivot, lateral move end tow, solid set,
or hand move irrigation systems, or certain other systems described in EPA-accepted
supplemental labeling. .
Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from
nonuniform distribution of chemigation treated water.
If you have questions about calibration you should contact state extension specialists, equipment
manufacturers, or other experts.
Do not connect an irrigation system (including greenhouse systems) used for pesticide application
to a public water system.
A person knowledgeable of the chemigation system and responsible for its operation, or under the
supervision of the responsible person, shall shut the system down and make necessary
adjustments should the need arise.
Sprinkler Chemigation Directions:
The following directions must be followed for all recommended sprinkler irrigation systems (center
pivot, lateral move, or end tow):
1. The system must contain a functional check valve, vacuum relief valve, and low pressure
drain appropriately located on the irrigation pipeline to prevent water source contamination
from back-flow.
2. The pesticide injection pipeline must contain a functional, automatic, quick-closing check
valve to prevent the flow of fluid back toward the injection pump.
3. The pesticide injection pipeline must also contain a functional, normally closed, solenoid
operated valve located on the intake side of the injection pump and connected to the system
interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system
is either automatically or manually shut down.
4. The system must contain functional interlocking controls to automatically shut off the pesticide
injection pump when the water pump motor stops.

"'-
(
US Sentry Trifluralinldraftl09-18/97 Page 15
5. The irrigation line or water pump must include a functional pressure switch which will stop the
water pump motor when the water pressure decreases to the point that pesticide distribution
is adversely affected.
6. Systems must use a metering pump, such as a positive displacement injection pump (e.g.,
diaphragm pump) effectively designed and constructed of materials that are compatible with
pesticides and capable of being fitted with a system interlock.
7. Do not apply when wind speed favors drift beyond the area intended for treatment.
8. US Sentry Trifluralin should be injected continuously throughout the chemigation period. The
chemigation metering pump should be checked periodically during application to insure proper
operation.
9. The injection metering pump must be calibrated as specified by the manufacturer.
10. Pesticide injection hoses which connect chemigation metering equipment to the sprinkler
irrigation system should be of braided reinforced construction with an internal tube made of
nylon, cross-linked polyethylene, or high density polyethylene.
11. US Sentry Trifluralin may cause staining of plastic hoses and tanks.
12. Apply US Sentry Trifluralin in sprinkler irrigation equal to 1/2 to 1 inch of water.
13. During chemigation, maintain agitation in supply tank at all times.
Chemigation System Calibration:
Sample calculation for use of US Sentry Trifluralin in a chemigation system:
• Assume, in this example, 133 acres are to be covered by a chemigation treatment.
• Product required, assuming 1.5 pints per acre is 199.5 pints
(133 acres X 1.5 ptlacre = 199.5 pt = 25 gallons)
• Add 25 gallons of product directly to the injection supply tank.
• Adjust the injection system to deliver 25 gallons during the time required to apply 1 inch of water
to 133 acres.
If the irrigation system requires 20 hours to apply 1 inch of water to 133 acres, the injection rate is
1.25 gallhr and is calculated as follOWS:
• 25 gal .;. 20 hr = 1.25 gallhr
1.25 gal/hr = 160 fI ozlhr
Proper calibration requires the injection pump to be adjusted to deliver 2.7 fl ozlmin and is
calculated as follows:
• 160 fl ozlhr .;. 60 min.lhr = 2.7 fl 02 per min.
Chemigation Mixing Directions:
Undiluted US Sentry TrifluraliA: When used alone, the injection of undiluted US Sentry
Trifluralin is recommended in chemigation systems. For undiluted use, the metering pump, supply
tank, and any associated equipment must be thoroughly clean and dry before US Sentry Trifluralin
is added to the system for injection. ''When injecting undiluted US Sentry Trifluralin, maintain
continuous agitation in the supply tank.
Diluted US Sentry Trifluralin: US Sentry Trifluralin may be diluted if required to achieve
accurate calibration for existing equipment. Partially fill the injection supply tank with a volume of
water equal to the amount of US Sentry Trifluralin required (Do not add water to US Sentry
Trifluralin). Start agitation. Add the required amount of US Sentry Trifluralin to water in the supply
tank and continue mixing while filling the tank to the final volume required by the injection pump
calibration. When injecting diluted US Sentry Trifluralin, maintain continuous agitation in supply
tank.
Application Timing

US Sentry Trifluralinidraftl09-18/97 Page 16
~pring Application
Apply and incorporate US Sentry Trifluralin any time after January 1 when soil can be worked and
is in a condition which allows thorough mixing to insure uniform incorporation. See "Approved
Crops" section for application timing recommendations for specific crops.
Fall Application
Fall application can be used for all crops for which US Sentry Trifluralin is recommended as a
preplant incorporated treatment. Refer to "Approved Crops" section for any crop specific fall
application instructions.
In the states of California, North Dakota, South Dakota and Minnesota, apply and incorporate US
Sentry Trifluralin any time between September 1 and December 31. In all other states, fall apply
US Sentry Trifluralin between October 15 and December 31.
Ground may be bedded up over winter. On bedded ground, reduce beds to desired height before
planting, by moving some treated soil from beds into furrows. Where soil is left flat over winter,
care should be taken not to turn up untreated soil during spring bedding operations. Destroy
established weeds during seedbed preparation. Weeds established in furrows as a result of
exposing untreated soil should be destroyed before planting. Fall application of US Sentry
Trifluralin is not recommended on fields which remain wet or are subject to periods of flooding.
Preemergence Application Immediately After Planting
Apply and incorporate US Sentry Trifluralin immediately after planting and prior to crop
germination. Adjust incorporation equipment so as to not disturb planted seed. Refer to the
"Approved Crops' section of this label for crop specific instructions.
Postemergence and Layby Application
Apply and incorporate US Sentry Trifluralin at the recommended rate to the established crop at or
before the last cultivation. Required preharvest intervals for treatments with US Sentry Trifluralin
for certain crops are specified in the· Approved Crops· section of this label. Crop cover may
prevent uniform soil coverage from over-the-top sprays. To avoid this problem, use drop nozzles
or directed sprays to achieve uniform soil coverage.
/ Incorporation Directions
Soil Preparation and Incorporation
Ground cover or existing weeds, can interfere with uniform soil incorporation of US Sentry
Trifluralin. A manageable level of ground cover will allow uniform incorporation into the top 2 to 3
inches of the final seedbed. Ground cover and crop residues, if excessive, should be reduced by
appropriate soil tillage prior to application.
US Sentry Trifluralin must be incorporated within 24 hours after application unless otherwise
specified on supplemental labeling. Non-uniform application may result in erratic weed control or
crop injury. With most equipment and methods of application, a second incorporation is required
and may occur any time before planting. The second incorporation should be in a different
direction, and to avoid bringing untreated soil to the surface, should not be deeper than the first.
Note: Two-pass incorporation is required for all special use programs unless otherwise
specified.
General Soil Conditions: The soil surface should be smooth enough to allow for uniform
application and efficient incorporation of US Sentry Trifluralin. Break up clods using tillage
equipment prior to application of US Sentry Trifluralin. Apply when soil moisture is sufficient to
allow the breakup of large clods and uniform mixing during the incorporation process. Soil
compaction and/or non-uniform incorporation may occur if soil is excessively moist.

US Sentry T rifluralinJdraftl09-18197
'i1!
Page 17 /-f Ct.!'
Incorporation in Bedded Culture: In bedded culture, WS Sentry Trifluralin should be
incorporated to a depth of 2 to 3 inches in the final seedbed.
Application Prior to Bedding: Apply US Sentry Trifluralin and incorporate 1 time with
recommended equipment. The bedding operation serves as the second incorporation. Do not
expose untreated soil during post-bedding operations such as planting since removal of treated
soil during planting can allow weed germination and establishment in the drill row.
Application After Bedding: Knock off beds to planting height before applying US Sentry
Trifluralin. Apply and incorporate US Sentry Trifluralin with recommended equipment that will
conform to the shape of the bed. Do not expose untreated soil.
Cultivation After Planting: Treated crops may be shallowly CUltivated without reducing the weed
control activity of US Sentry Trifluralin. Limit depth of cultivation to the zone of treated soil to
avoid moving untreated soil to the surface. Exposure of untreated soil may cause loss of weed
control.
Incorporation Equipment
Use incorporation equipment capable of mixing US Sentry Trifluralin uniformly into the top 2 to 3
inches of the final seedbed. Use of inappropriate equipment or improper use of recommended
equipment may result in erratic weed control and/or crop injury. Incorporation equipment such as
a tandem disc will mix US Sentry Trifluralin approximately half as deep as the equipment is set to
operate. For example, a disc set to cut 4 inches deep will mix most of the US Sentry Trifluralin
within the top 2 inches of soil. Any recommended incorporation implement may be used alone or
in combination with any other recommended implement. Two incorporation passes are required
when using the following incorporation implements (for single pass incorporation, refer to soil
conditions and equipment listed under Single Pass Incorporation Option below):
Tandem Disc: Set equipment to cut 4 to 6 inches deep and operate at 4 to 6 mph.
Rolling Cultivator: Set equipment to cut 2 to 4 inches deep and operate at 6 to 8 mph.
Bed Conditioner (DO-All): Set equipment to cut 2 to 4 inches deep and operate at 4 to 6 mph.
One incorporation pass is adequate in bedded culture, while 2 incorporation passes are required
in flat planted culture. The Do-All should be used only on coarse and medium textured soils.
Mulch Treader and other similar disc-type implements: Set equipment to cut 3 to 4 inches
deep and operate at 5 to 8 mph.
Other Equipment: Other implements including the flexible tine-tooth harrow (Flextine or Melroe),
are recommended, but only for certain uses defined in the' Approved Crops" section of this label.
Conservation Tillage Practices: In reduced or minimum tillage situations, fall or spring
application and incorporation of US Sentry Triffuralin may be combined with tillage operations.
The first incorporation may utilize equipment such as a tandem disc, combination implement or
bedding equipment that provides gobd soil mixing but leaves a maximum amount of crop residue
on the soil surface. The second incorporation may be accomplished with tillage equipment that
provides uniform soil mixing used in conjunction with no-till planters (See specific
recommendations for reduced or conservation tillage situations for cotton and soybeans in the
"Approved Crops' section).
Single Pass Incorporation Option
US Sentry Trifluralin may be incorporated in a single pass if incorporation conditions allow for
thorough and uniform mixing into the top 2 to 3 inches of the final seedbed. Thorough and
uniform incorporation may be achieved if the soil at the time of incorporation is of good tilth with
moderate moisture, and is relatively free of clods and crop residue. The following types of
equipment can be used to obtain thorough and uniform soil mixing from a single
incorporation pass:

US Sentry Trifluralinidraftl09-18/97
Finishing Disc with disc blades no greater than 22 inches in diameter, spaced no more than 7
1/2 inches apart. Operate at 4 to 6 mph. Best results are obtained when the disc is equipped with
harrow, reel, or basket attachments.
Field Cultivator: Set equipment to cut 3 to 4 inches deep and operate at a minimum of 5 mph. A
field cUltivator is defined as an implement with 3 to 4 rows of sweeps, spaced at intervals of 7
inches or less with sweeps on successive rows staggered so that no scil is left untumed. Chisel
points should not be used. Best results are obtained when the field cultivator is equipped with
harrow, reel, or basket attachments.
Combination Implements: These implements are defined as 2 or more tillage devices combined
to operate as a single tillage unit. For example, 2 to 3 rows of field cultivator C- or S-shaped
shanks with successive rows of sweeps staggered so that no soil is left unturned, followed by a
spike-tooth or flextine harrow, followed by ground driven reel, basket or incorporator wheels.
Combination implements should be set to cut 3 to 4 inches deep and operated at a minimum of 6
mph. Two incorporations are recommended under conditions which prevent optimum soil mixing
such as excessive surface residue, roughness, high clay content or soil is too wet or too dry.
Combination tools can also be composed of 2 rows of wide crown sweeps that overlap so that the
roots of all weeds and plants are severed. This should be followed by 2 gangs of rotating spoked
wheels that thoroughly mix US Sentry Trifluralin into the top 2 to 3 inches of the final seedbed.
P.T.O.-Driven Equipment (tillers, cultivators, hoes): Adjust equipment to incorporate US
Sentry Trifluralin into the top 2 to 3 inches of the final seedbed with rotors spaced to provide a
clean sweep of the soil. P.T.O. equipment should not be operated more than 4 mph.

Surface Applications Activated by Rainfall or Irrigation
Broadcast surface applications of US Sentry Trifl.lralin to established alfalfa may be activated by
rainfall, sprinkler, flood, or furrow irrigation. Rairrall or a single overhead sprinkler irrigation of 0.5
acre inch or more is required to activate US Sen:ry Trifluralin. If activated by furrow irrigation,
care should be taken to thorougtJly wet beds between furrows. If rainfall or irrigation has not
occurred within 3 days after application, US Semry Trifluralin may be mechanically incorporated.
If mechanically incorporated, use equipment that will insure thorough soil mixing with minimum
damage to the established alfalfa..
Application Timing and Weeds Controlled
Applications to established alfalfa for annual grass control can be made during dormancy or semi
dormancy, or during the growing season immed~tely after a cutting. Because US Sentry
Trifluralin does not control established weeds, ap:llication must be made prior to the expected
time of weed germination. Bromegrass and cheat begin to germinate in the fall with the onset of .
cooler weather. To control these weeds, apply US Sentry Trifluralin immediately after a Gutting
between August 1 and October 1, but prior to weed germination. When fall applied, US Sentry
Trifluralin controls bromegrass and cheat in addlfon to other labeled weeds that germinate after
application.

Postemergence Incorporated Treatment
Apply US Sentry Trifluralin as a postemergence treatment following cultivation and/or use of a
preemergence herbicide. US Sentry Trifluralin does not control established weeds. Apply when
crop is well established (2 true 'leaf stage or taller). Apply as an over-the-top spray or as a
directed spray using drop nozzles if foliage prevents uniform coverage of the soil surface.
Incorporation Directions
Applications of US Sentry Trifluralin must be mechanically incorporated within 24 hours.
Mechanical incorporation may be accomplished with 1 pass of a sweep-type cultivator or properly
adjusted rolling cultivator. The sweep-type cultivator should have 3 to 5 sweeps per row middle
and be operated at a speed that will provide vigorous soil mixing. Set middle sweeps so as to
avoid exposing untreated soil. Adjust incorporation equipment so as to avoid mechanical injury to
the crop.
Water In Option for Coarse and Medium Textured Soils: On coarse and medium textured
soils, US Sentry Trifluralin may be incorporated by continuous rainfall or sprinkler irrigation

amounting to at least 1/2 to 1 inch of water. Best results are obtained if application is made
immediately after a cUltivation when the soil surface is open and porous. Rainfall or sprinkler
irrigation prior to application will tend to consolidate and seal the soil surface and prevent the
downward moment of US Sentry Trifluralin that is expected under porous, open, recently tilled
conditions. Supplemental irrigation can be applied through a center pivot, solid set, or hand
moved sprinkler system. Do not use furrow irrigation. Mechanically incorporate as described

Tank Mixing or Sequential Treatments
For broader spectrum weed control, other products registered for use in cotton may be applied in
tank mix combination with US Sentry Trifluralin or as a sequential treatment following application
of US Sentry Trifluralin. When tank mixing, use the recommended rate of US Sentry Trifluralin.
Follow the label "Directions for Use" of each tank mix partner for applicable use instructions
including application rate, application timing, weeds controlled, and specific precautions and
restrictions of product use. See detailed information for tank mixing in the "General Information"
section of this label.
/ Special Use Programs
1. Cotton - Chemigation
US Sentry Trifluralin may be applied through properly equipped chemigation systems for weed
control in cotton. Refer to "Application by Chemigation" in the "General Information" section of this
label for use directions for chemigation. Do not apply US Sentry Trifluralin through any type of
irrigation sysfem unless these directions are carefully followed.
Apply US Sentry Trifluralin in overhead sprinkler irrigation equal to 1/2 to 1 inch of water. Planting
and application should occur as soon as possible after the last tillage operation. US Sentry
Trifluralin must be applied within 2 days after planting prior to crop emergence. US Sentry
Trifluralin does not control established weeds. Soil incorporation is not required when US Sentry
Trifluralin is applied through chemigation systems.
Broadcast Application Rates/Acre for Chemigation Application Where Conventional Tillage
Practices are Used: See rates for cotton "US Sentry Trifluralin - Alone" above. Apply at the
maximum recommended rate for spring application for each soil texture class to be treated.
Cultivation: Soil treated by chemigation with US Sentry Trifluralin may be shallow cultivated
without reducing weed control activity.

Use the lower rate in the rate rantle when additional sequential applications of US Sentry
Trifluralin are anticipated. Use the higher rate in the rate range when high crop residue levels are
present, where dense weed populations are anticipated, or where no additional sequential
applications of US Sentry Trifluralin are to be made.
Rotational Crop Restrictions
• Conventional Tillage: Refer to the rotational crop restrictions in the "General Use Precautions"
section of this label.
• Minimum Tillage: In addition to the rotational crop restrictions listed in the General Use
Precautions section of this label, do not plant grain sorghum in the year following the application
of US Sentry T rifluralin.
2. Cotton - Weed Control in Conservation Tillage
This section describes application methods and techniques for weed control with US Sentry
Trifluralin in conservation tillage cotton. US Sentry Trifluralin may be applied and incorporated in

Strip Planting into Small Grain Cover Crops
Fall planted cover crops may be utilized to control wind erosion and protect developing crop
seedlings from wind damage. Prior to planting cotton, the cover crop may be treated with a
contact herbicide to prevent continued growth and development and prevent competition with crop
seedlings for water and soil nutrients. The standing cover crop (now dead) continues to control
wind erosion and provide protection to the developing crop until it is well established.
Strip Planting: In strip planting, cotton is seeded into competition-free bands established in the
cover crop. Competition-free bands may be established by leaving unseeded drill rows when
seeding the cover crop, by tillage, or by use of a contact herbicide to prepare competition-free
bands prior to planting.
Fall Application Before Establishing a Cover Crop
Small grain cover crops (wheat, barley or rye) may be established following a preplant
incorporated application of US Sentry Trifluralin. Apply US Sentry Trifluralin to flat ground at a
broadcast rate of 2.0 to 3.0 pints per acre and incorporate once within 24 hours using
incorporation implements that can be set to cut no more than 2 to 3 inches deep, such as a
springtooth harrow. Do not incorporate with a tandem disc. Form beds with disc bedders or
other bedding implements that will mix and move most of the treated soil from the furrows to the
beds. Phosphate and other fertilizer may be applied as appropriate during incorporation
operations. Plant 2 to 4 rows of the small grain cover crop 2 inches deep in the furrows between
the beds. To avoid injury to small grain seedlings, place seed below the treated layer of soil.
Sarley is usually less susceptible to injury than wheat or rye. Soil moisture must be adequate to
establish and maintain the cover crop. In late winter (February), apply 2,4-0 if necessary for
broadleaf weed control.
Spring Application Before or After Planting (Within Competition-Free Bands)
Apply US Sentry Trifluralin using low pressure ground equipment as a band (within the weed free
zone) or as a broadcast treatment. Application and incorporation may occur before planting or
after planting prior to crop emergence. If applied after planting, set incorporation equipment so as
to not disturb the planted seed (~ee incorporation instructions).
Incorporation: Equipment should be adapted to the width of the competition-free band. Use
equipment that will uniformly mix US Sentry Trifluralin into the weed germination zone. Weed
control resulting from single pass incorporation or with incorporation equipment that does not
result in thorough mixing of soil treated with US Sentry Trifluralin may be reduced compared to
conventional double pass incorporation. Implements used to incorporate US Sentry Trifluralin
after planting should be operated so that they do not disturb the planted seed or growing crop.
Use the lower rate in the rate range when additional sequential applications of US Sentry
Trifluralin are anticipated. Use the higher rate in the rate range where high crop residues are
present, and where dense weed populations are anticipated.
For band treatments, reduce the application rate in proportion to the row spacing and band width
treated. For example, treating a 12-inch band where the row spacing is 36 inches would require
1/3 of the recommended broadcast rate per acre (12 inches divided by 36 inches = 1/3).
Layby Applications

US Sentry Trifluralin/draW09-18/97 Page 31
Layby applications may be made in established cotton from the 4 true leaf stage of growth up to
layby, but not less than 90 days before harvest. Apply US Sentry Trifluralin uniformly to the soil
surface using drop nozzles if necessary. Soil incorporate using 1 pass of a sweep-type CUltivator
or properly adjusted rolling cultivator. Operate CUltivation equipment at speeds sufficient to
provide vigorous soil mixing and exercise care to avoid mechanical injury to the crop. CU,mulative
layby application rate may not exceed the layby application rate shown for each soil texture.

/ SMALL GRAINS - BARLEY, DURUM, AND WHEAT
.
Special Precautions for Use of US Sentry Trifluralin on Small Grains
Carefully follow directions for use of US Sentry Trifluralin on small grains to minimize potential
crop stress. Under certain conditions, delayed crop emergence and or stand reduction may occur
when US Sentry Trifluralin is applied to barley, durum, or wheat. The combined effect of certain
cultural practices and unfavorable soil or environmental conditions may cause excessive crop
seedling stress resulting in retarded crop growth, stand reduction, and possibly reduced yield.
For best results, observe the following cultural practices or precautions:
Use tillage methods that provide a uniformly firm seedbed and time tillage operations to conserve
moisture.
Irrigate prior to planting or after germination and emergence. Moisture received between planting
and emergence may cause crusting, especially on loose seedbeds.

US Sentry Trifluralinidraftl09-18/97 Page 44
Do not exceed recommended application rates for US Sentry Trifluralin. This is particularly
important on coarse textured or low organic matter soils.
Carefully follow incorporation directions. When applying preplant incorporated treatments,
operate equipment at recommended depth and speed to place US Sentry Trifluralin into the upper
1 to 1 1/2 inches of soil. If applied after planting, set equipment so as to not disturb planted seed.
Set drills to place seed at a the depth specified in use directions. A planting depth greater than 2
1/2 inches for spring wheat or durum will result in increased seedling stress 1:ind decreased
emergence.
Use only high quality seed where US Sentry Trifluralin is to be applied (avoid use of small seed
with low starch reserves).
If seed treatments are used, apply at the correct rate and uniformly across all seeds.
Misapplication may result in reduced germination and/or seedling vigor.
Avoid use of seed varieties known to have poor seedling (emergence) vigor.
Soil characteristics and environmental conditions which may contribute to crop seedling
stress that may be accentuated by use of US Sentry Trifluralin include:
Soil related: High salinity, eroded knolls/hilltops, loose dry soils and compaction.
Weather related: Cold and/or wet soils, excessively hot soils, excessive moisture, drought, and
soil crusting from heavy rainfall.
Note: Do not apply US Sentry Trifluralin on small grains where a dinitroaniline herbicide
such as US Sentry Trifluralin or Sonalan- herbicide was applied at a rate greater than 0.5 Ib
ai per acre the previous growing season.

tFali Application Rates for States Including: Alabama, Arkansas, northem Florida, Georgia,
Louisiana, Mississippi, southeastern Missouri (Bootheel), North Carolina, Oklahoma, South
Carolina, Tennessee, and Texas.
For soybeans grown in states other than those listed above, fall apply US Sentry Trifluralin at
broadcast rates recommended for spring preplant incorporated treatment.
Precautions: Soybeans should be planted after early season adverse weather conditions have
passed, especially when using higher rate programs. Cool, wet weather early in the growth cycle
causes additional stress on soybean plants which may result in reduced stand, delayed maturity
and reduced yield.
Tank Mix Overlay and Postemergence Recommendations
For broader spectrum weed control"other products registered for use in soybeans may be applied
in tank mix combination with US Sentry Tritluralin or as a sequential treatment following
application of US Sentry Trifluralin. When tank mixing, use the recommended rate of US Sentry
Trifluralin. Follow the label "Directions for Use" of each tank mix partner for applicable use
instructions including application rate, application timing, weeds controlled, and specific
precautions and restrictions of product use. See detailed information for tank mixing in the
"General Information" section of this label.
/ Special Use Programs
1. Soybeans - Chemigation
US Sentry Trifluralin may be applied through properly equipped chemigation systems for weed
control in soybeans. Refer to "Application by Chemigation" in the "General Information" section of

I?,/
US Sentry Trifluralin/draft/09-1 8/97 I (;~ page4/ .
this label for use directions for chemigation. Do not apply US Sentry Trifluralin through any
irrigation system unless these directions are carefully followed.
Apply US Sentry Tritluralin in sprinkler irrigation equal to 1/2 to 1 inch of water. Planting and
application should occur as soon as possible after the last tillage operation. US Sentry Trifluralin
must be applied within 2 days after planting and prior to crop emergence. US Sentry Trifluralin
does not control established weeds. Soil incorporation is not required when US Sentry Trifluralin
is applied through chemigation systems.

• Soils with 5% to 10% organic matter - 2.0 to 2.5 pints
Cultivation: Soil treated by chemigation with US Sentry Trifluralin may be shallow cultivated
without reducing weed control activity.
2. Soybeans - Weed Control Under Reduced or Conservation Tillage
US Sentry Trifluralin can be applied either in the fall or in the spring as a preplant incorporated
treatment for weed control in soybeans grown under reduced or conservation tillage conditions.
Make only 1 application per crop cycle.
Apply to tilled land or standing or chopped stubble from the previous season's crop. The first
incorporation of US Sentry Trifluralin must occur within 24 hours. For the first incorporation, a
tandem disc or combination tool that can thoroughly mix US Sentry Tritluralin into the top 2 to 3
inches of the final seedbed while leaving the desired amount of plant residue on the soil surface is
recommended. For fall or spring application, the second incorporation can occur anytime prior to
planting or at planting with tillage equipment that provides uniform soil mixing used in conjunction
with no-till planters.
Application With Dry Bulk Fertilizers
Dry bulk fertilizers impregnated or coated with US Sentry Tritluralin may be applied as a preplant
incorporated treatment. See instructions for "Application with Dry Bulk Fertilizer' in the "General
Information" section of this labe/. Under reduced or conservation tillage conditions, uniformly
applied dry bulk fertilizers impregnated with US Sentry Trifluralin provide weed and grass control
equal to or better than US Sentry Trifluralin applied in liquid sprays. Two incorporation passes are
required when US Sentry Trifluralin is applied with dry bulk fertilizer. For best results with spring
applications, incorporate once withirt 24 hours after application and a second time at least 5 days
later.

7. Soybeans - Charcoal Soils in Arkansas, Louisiana, and Mississippi
Newly cleared land often contains high organic matter (5-10%) and charcoal from burning debris.
Charcoal and organic matter tends to bind US Sentry Trifluralin and reduce weed control activity.
Under these conditions, higher rates of US Sentry TrifluraJin are necessary for weed control.
Increased rates, however, can cause crop injury if charcoal or organic matter is not present to
bind some of the US Sentry Trifluralin. In the bum row a high level of charcoal is usually present.
Consequently, poor weed control may result, even if an increased rate of US Sentry Trifluralin is
used. Follow recommended application and incorporation procedures for US Sentry Trifluralin.

Directions for Use
US Sentry Trifluralin herbicide may be spring applied as a preplant incorporated treatment for foxtail (pigeongrass)
control in spring seeded barley grown under irrigated conditions in Montana. US Sentry T rifluralin may be applied to
ground that has a manageable trash level or has been fallowed or pretilled. The first incorporation is required within
24 hours after application. The second incorporation is required prior to planting to destroy emerged weeds and to
ensure even distribution of US Sentry Trifluralin in treated soil .
Broadcast Application Rate: Apply US Sentry Trifluralin, at a rate of 1 pint per acre regardless of soil texture or soil
organiC matter content. Do not exceed this application rate as crop injury may occur.
Incorporation Directions
The following tools are recommended for soil incorporation:
1. Chisel Plow alone or Chisel Plow with a Rod Weeder attached: A chisel plow alone should be used for the
first incorporation pass only. With rod weeder attached, the chisel plow may be used for both incorporation
passes. Operate 4 to 5 inches deep and at 4 to 6 mph. A chisel plow is defined as having three rows of up to 18
inch sweeps on no greater than 12 inch centers. Stagger successive rows of sweeps to ensure that no soil is left
unturned.
2. Tandem Disc: Operate 3 to 4 inches deep and at 4 to 6 mph.
3. Field Cultivator: Operate 3 to 4 inches deep and at 5 or more mph. A field cultivator is defined as having 3 to 4
rows of sweeps with 'C" or ·S· shaped shanks spaced at intervals of 7 inches or less. Stagger successive rows
of sweeps to ensure that no soil is ~ft untumed.
Planting Directions
Plant barley 1 to 2 inches deep. Planting greater than 2 inches deep will result in increased seedling stress and
decreased emergence.
Irrigation Directions
Irrigate prior to planting, or after crop emergence only. Irrigation between planting and emergence may cause
reduced crop stands or delayed emergence because of soil crusting, especially on loose friable seedbeds.
Use Precautions: Carefully follow Special Use Precautions for Small Grains in main product label.
Rotational Crop Planting Restrictions
Plant only barley (grown under irrigated conditions), rapeseed, safflower or sunflower as a rotational crop in the year
following the crop treated with US Sentry Trifluralin. If one of the specified rotational crops is not planted, the land
should be left idle or fallow for the entire crop year following the crop treated with US Sentry Trifluralin.
