Product Information
Sentry Trifluralin 4EC herbicide is a herbicide for the preemergence con trol of annual grasses and broadleaf weeds. Sentry
Trifluralin 4EC may be applied in liquid sprays of water or liquid fertilizer, or impregnated on dry bulk fertilizer. To reduce loss
of herbicidal activity, Sentry Trifluralin 4EC should be soil incorporated within 24 hours after application unless otherwise
specified in specific use directions or supplemental labeling. Sentry Trifluralin 4EC may be tank mixed or followed by overlay or 
postemergence treatments with other herbicides to improve the spectrum of weeds contro lled. Sentry Trifluralin 4EC controls
weeds by disrupting growth processes during germination. Sentry Trifl uralin 4EC does not control established weeds.
Product Use Precautions
Applied according to directions and under normal growing conditions, Se ntry Trifluralin 4EC will not harm the treated crop. 
Over application may result in crop injury or rotational crop damage from herbicide carryover. Uneven application or improper 
incorporation of Sentry Trifluralin 4EC 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 poss ibility of
damage from Sentry Trifluralin 4EC. Under these conditions, delayed cro p development or reduced yields may result.
Do not apply Sentry Trifluralin 4EC to soils that are wet or are subject to prolonged periods of flooding as poor weed control
may result.
Do not use Sentry Trifluralin 4EC on any crop grown in Pecos county or Reeves county, Texas.

Page 5 of 45 
 
In Montana, uses of Sentry Trifluralin 4EC are limited to those described in supplemental labeling. Refer to
supplemental labeling for crops and specific use directions.
Chemigation Sentry Trifluralin 4EG may be applied by chemigation on certain crops; See instructions for- ------
crops in the Crops section of this label.
Rotation Crop Restrictions
Sugar Beets, Red Beets, and Spinach.
In Arizona, Colorado, California, Idaho, Nevada, New Mexico, Oregon, Uta h, Washington, and Wyoming: Sugar
beets, red beets, or spinach should not be planted for 12 months after a spri ng application or 14 months after a fall
application of Sentry Trifluralin 4EC. Moldboard plowing to a depth of 12 inches prior to planting these crops will reduce
the possibility of crop injury. If land has not been irrigated, these cr ops should not be planted for 18 months after a
spring application or 20 months after a fall application of Sentry Trifluralin 4EC.
In all other areas: Sugar beets, red beets, and spinach should not be planted for 12 months afte r a spring application or
14 months after a fall application. Before planting sugar beets, moldbo ard plow to a depth of 12 inches to reduce the
possibility of crop injury.
Proso Millet, Corn, Sorghum {Milo), Oats, and Annual or Perennial Grass C rops or Grass Mixtures In Arizona,
Colorado, California, Idaho, Nevada, New Mexico, Oregon, Utah, Washingt on, and Wyoming: Unless crop injury is
acceptable, proso millet, corn, sorghum (milo), oats, and annual or per ennial grass crops or grass mixtures should not
be planted for 12 months after a spring application or 14 months after a fall application of Sentry Trifluralin 4EC to avoid
the possibility of crop injury. If land has not been irrigated, these crops should not be planted for 18 months after a
spring application or 20 months after a fall application. Moldboard plow ing to a depth of 12 inches before planting these
crops will reduce the possibility of crop injury.
In Minnesota, North Dakota, and South Dakota: Unless crop injury is acceptable, proso millet, sorghum (milo), oats,
and annual or perennial grass crops or grass mixtures should not be planted for 18 months after a spring application or 21
months after a fall application of Sentry Trifluralin 4EC.
In those portions of Kansas, Nebraska, Oklahoma, and Texas that receive l ess than 20 inches of rainfall and irrigation
to produce a crop: Unless crop injury is acceptable, do not plant proso millet, sorghum (milo), oats and annual or perennial
grass crops or grass mixtures for 18 months after an application of Sentry Trifluralin 4EC. In sorghum, cool, wet weather
conditions 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 Sentry Trifluralin 4EC.
Rotation Crops Other Than Those Specifically Addressed Above
Crops, other than those to which Sentry Trifluralin 4EC may be applied as a preplant soil incorporated treatment, should not be
planted within 5 months after an application of Sentry Trifluralin 4EC.
Soil Texture Guide for Application Rates
Rate specifications for incorporated treatments of Sentry Trifluralin 4 EC are based on Soil Texture Class (coarse, medium, or
fine) and soil organic matter content. A fine textured soil (e.g., clay lo am) 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 f ine) corresponding to the Soil Texture to be Treated. Choose the proper rate for each
application based on the Soil Texture Class and specific crop instructio ns. Do not exceed specified rates.
Soil Texture Class Soil Texture to be Treated
Coarse (Light) Soils Sand, loamy sand, sandy loam
Medium Soils Loam, silty clay loam 1, silt loam, silt, sandy clay
loam

Mixing Directions
Sentry Trifluralin 4EC - Alone
Sentry Trifluralin 4EC may be mixed with water or most liquid fertilizer ma terials. Prior to mixing Sentry Trifluralin 4EC in liquid
fertilizer, 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 Sentry Trifluralin 4EC 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. Star t agitation. Add correct amount of Sentry Trifluralin 4EC
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.
Sentry Trifluralin 4EC in Tank Mix
For broader spectrum weed control, Sentry Trifluralin 4EC may be applied i n 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 specified rate of Sentry Trifluralin 4EC. 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.
Sentry Trifluralin 4EC may be tank mixed with other products and applied with water or most liquid fertilizer materials. Prior to
mixing Sentry Trifluralin 4EC with other pesticides or liquid fertilizers, refer to the Compatibility Testing for Tank Mix Partners
Including Liquid Fertilizers section below.
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 a gitation. 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 (WP); aqueous suspensions (AS),
flowables (F) and liquids (L).
Maintain agitation and fill spray tank to 3/4 of total spray volume. Add S entry Trifluralin 4EC and other emulsifiable
concentrates (EC) and any solutions (S).
Finish filling the spray tank. Maintain continuous agitation during mi xing, 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 par ticularly 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 t o 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 ad ded to the spray tank through a 20
to 35 mesh screen. This procedure assures good initial dispersion of the se products in liquid fertilizer or water. Line
screens in the spray tank should be no finer than 50 mesh (100 mesh is finer than 50 mesh).
Compatibility Testing for Tank Mix Partners Including Liquid Fertilizers
A jar test is directed prior to tank mixing this product with other pesticid es or liquid fertilizer to ensure compatibility. Use a
clear glass quart jar with lid and mix the tank mix ingredients in their rela tive proportions and in the order indicated in the
tank mixing section above. Invert the jar containing the mixture several times and observe the mixture for approximately
1/2 hour. If components of the mixture separate readily, a compatibility agent may be helpful in maintaining the stability of
the spray mixture. If the mixture balls-up, forms flakes, sludges, jels, oily films or layers , or other precipitates, the
components of the mixture are not compatible and full-scale tank mixing should not be a ttempted.

Page 7 of 45 
 
Note: Compliance with state regulations for liquid fertilizer mixing, registration, labeling, and application are the
responsibility of the individual and/or company offering the fertilizer or chemical mixture for sale.
Application Methods
General: As spray volume decreases, the importance of accurate calibration and un iform application increases. Check
calibration and uniformity of spray application daily. To avoid spray dr ift, do not apply when winds are gusting or when wind
speed is greater than 15 mph.
Ground Broadcast Application
Apply Sentry Trifluralin 4EC 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 car rier may be water or liquid fertilizer as specified for the
crop to be treated in the 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 Sentry Trifluralin 4EC in 5 to 10 gallons of water per acre. Adjust pum p pressure, nozzle arrangements, speed, and
application height to provide uniform application to the soil surface. U se swath markers or flaggers to assure proper swath
width interval.
Avoiding Spray Drift: Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many
equipment-and-weather related factors determine the potential for spra y drift. The applicator and the grower are responsible
for considering all these factors when making decisions.
The following spray drift management practices are specified to avoid of f-target movement of sprays:
x The distance from the outer most nozzles on the spray boom must not exceed 3/ 4 the length of the wingspan or
rotor.·
x Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45
degrees.
Information On Droplet Size: The most effective way to reduce drift p otential is to apply large droplet s. The best drift
management strategy is to apply the largest droplets that provide suffi cient 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).
x Volume - Use high flow rate nozzles to apply the highest practical spray volume. No zzles with higher rated flows
produce larger droplets.
x Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For man y nozzle types lower 
pressure produces larger droplets. When higher flow rates are needed, us e higher flow rate nozzles instead of
increasing pressure.
x Number of Nozzles - Use the minimum number of nozzles that provide uniform coverage.
x Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the air stream p roduces larger droplets
than other orientations and is the recommended practice. Significant def lection from horizontal will reduce droplet size
and increase drift potential.
x Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray
angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back produce
the largest droplets and the lowest drift.
Boom Length: 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 to p of the largest plants
unless a greater height is required for aircraft safety. Making applica tions 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 increase, with increasing drift potential (higher wind, smaller drops, etc.).
Wind: Drift potential is lowest between wind speeds of 2 to 10 mph. However, man y factors, including droplet size and
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 fa miliar

Page 8 of 45 
 
with local wind patterns and how they affect spray drift.
Temperature and Humidity: When making applications in low relative humidity, set up equipment to pro duce larger droplets
to compensate for evaporation. Droplet evaporation is most severe whe n conditions are both hot and dry.
Temperature Inversions: Applications should not occur during a local, low-level temperature inv ersion because drift potential
is high. Temperature inversions restrict vertical air mixing, which caus es small- suspended droplets to remain in a
concentrated cloud. This cloud ca n 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 limi ted
cloud cover and light to no wind. They begin to form as the sun sets and often continue into the morning . Their presence can
be indicated by ground fog; however, if fog is not present, inversions can also be identified by the movement of the smoke from
a ground source or an aircraft smoke generator. Smoke that layers and move s 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.
Sensitive Areas: The pesticide should only be applied when the potential for drift to adjac ent sensitive areas (e.g., residential
areas, bodies of water, known habitat for threatened or endangered specie s, non- target crops) is minimal (e.g., when wind is
blowing away from the sensitive areas).
Application with Dry Bulk Fertilizer
Dry bulk fertilizers impregnated or coated with Sentry Trifluralin 4EC ma y be applied as a preplant incorporated treatment on
crops. All label instructions for Sentry Trifluralin 4EC regarding appl ication rates, incorporation directions, special instructions,
and precautions must be followed. Read and follow all label instruction s below concerning use of Sentry Trifluralin 4EC with 
dry bulk fertilizer. Properly applied dry bulk fertilizers impregnated with Sentry Trifluralin 4EC provides weed and grass control 
equal to water sprays.

broadcast rate per acre. Any commonly used dry fertilizer can be used for im pregnation with Sentry Trifluralin 4EC except
coated ammonium nitrate and pure limes tone. These materials will not abso rb the herbicide. Blends containing mixtures of
these materials can be impregnated.
Impregnation: Use any closed drum, belt, ribbon, or other commonly used dry bulk fertili zer blender. Nozzles used to apply
Sentry Trifluralin 4EC to dry bulk fertilizer should be placed to provide uniform spray coverage.
Application and Incorporation: Spread the fertilizer/chemical mixt ure with properly calibrated applic ation equipment. Be
certain the material is applied uniformly to the soil surface. Dry bulk f ertilizer impregnated with Sentry Trifluralin 4EC must be
incorporated two times. The first in corporation 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 rela ting to dry bulk fertilizer blendi ng, registration,
labeling, and application are the res ponsibility of the individual and/o r company offering the fertilizer or chemical mixture for
sale.
Application by Chemigation
Sentry Trifluralin 4EC may be applied through properly equipped chemigat ion systems for weed control in certain crops as
specified in the Crops section of this label. Read and follow all label ins tructions outlined below concerning chemigation before
applying Sentry Trifluralin 4EC by this method.
General Chemigation Directions:
Apply this product only through continuously moving center pivot, later al move end tow, solid set, or hand move irrigation
systems, or certain other systems des cribed in EPA-accepted supplemental labeling.
Crop injury, lack of effectiveness, or illegal pesticide residues in the c rop 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 f or pesticide application to a public water system.
A person knowledgeable of the chemigation system and responsible for its o peration, or under the supervision of the
responsible person, shall shut the system down and make necessary adjustm ents should the need arise.
Sprinkler Chemigation Directions:
The following directions must be followed for all specified 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.
5. The irrigation line or water pump must include a functional pressure switc h which will stop the water pump motor when the
water pressure decreases to the point that pesticide distribution is ad versely affected.
6. Systems must use a metering pump, such as a positive displacement injectio n 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. Sentry Trifluralin 4EC should be injected continuously throughout the ch emigation period. The chemigation-metering
pump should be checked periodically during application to insure prope r operation.
9. The injection-metering pump must be calibrated as specified by the manufa cturer.
10. Pesticide injection hoses which connect chemigation-metering equipmen t to the sprinkler irrigation system should be of
braided reinforced construction with an internal tube made of nylon, cros s-linked polyethylene, or high-density polyethylene.
11. Sentry Trifluralin 4EC may cause staining of plastic hoses and tanks.
12. Apply Sentry Trifluralin 4EC 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 Sentry Trifluralin 4EC in a chemigation system:
x Assume, in this example, 133 acres are to be covered by a chemigation treatm ent.
x Product required, assuming 1.5 pints per acre, is 199.5 pints
x (133 acres X 1.5 pt/acre = 199.5 pt = 25 Gallons)
x Add 25 gallons of product directly to the injection supply tank.
x Adjust the injection system to deliver 25 gallons during the time require d 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 gal/hr and is calculated
as follows:
• 25 gal + 20 hr = 1.25 gal/hr
1.25 gal/hr = 160 fl oz/hr
Proper calibration requires the injection pump to be adjusted to deliver 2 .7 fl oz/min and is calculated as follows:
• 160 fl oz/hr + 60 min./hr = 2.7 fl oz per min.
Chemigation Mixing Directions:
Undiluted Sentry Trifluralin 4EC: When used alone, the injection of undiluted Sentry Trifluralin 4EC is dir ected in
chemigation systems. For undiluted use, the metering pump, supply tank, and any associated equipment must be thoroughly
clean and dry before Sentry Trifluralin 4EC is added to the system for
Injection. When injecting undiluted Sentry Trifluralin 4EC, maintain continuous agitation in the supply tank.
Diluted Sentry Trifluralin 4EC: Sentry Trifluralin 4EC may be diluted if required to achieve accurate calibration for existing
equipment. Partially fill the injection supply tank with a volume of wat er equal to the amount of Sentry Trifluralin 4EC
required (do not add water to Sentry Trifluralin 4EC). Start agitation. Add the required amount of Sentry Trifluralin 4EC 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 dilu ted Sentry Trifluralin 4EC, maintain continuous agitation in supply tank.
Application Timing
Preplant Incorporated Application
Sentry Trifluralin 4EC may be applied and incorporated prior to planting w hen soil can be worked and is in a condition that
allows thorough mixing to insure uniform incorporation. See Crops sec tion for application timing instructions for specific crops.
Preemergence Application Immediately After Planting
Apply and incorporate Sentry Trifluralin 4EC immediately after planting·and prior to crop germination. Adjust incorporation
equipment so as to avoid disturbance of planted seed. Refer to the Crops s ection of this label for crop specific instructions.
Postemergence and Layby Application
Apply and incorporate Sentry Trifluralin 4EC at the specified rate to the e stablished crop at or before the last cultivation. 
Required preharvest intervals for treatments with Sentry Trifluralin 4EC for certain crops are specified in the 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.
Fall Application
Sentry Trifluralin 4EC may be applied in the fall for weed control in the cro p of the following growing season in all crops for
which Sentry Trifluralin 4EC is specified as a preplant incorporated treatment. Refer to the Crops section for any crop specific 
fall application instructions. In the states of California, North Dakota, South Dakota and Minnesota, apply and incorporate
Sentry Trifluralin 4EC any time between September 1 and December 31. In al l other states, fall apply Sentry Trifluralin 4EC
between October 15 and December 31.
Fall application of Sentry Trifluralin 4EC is not specified on fields which remain wet or are subject to periods of flooding. 
Ground may be bedded up over winter. On bedded ground, reduce beds to desir ed height before planting, by moving some
treated soil from beds into furrows. Where soil is left flat over winter, care must be taken not to turn up untreated soil during
spring bedding operations. Destroy established weeds during seedbed preparation. Weeds established in furr ows as a result
of exposing untreated soil must be destroyed before planting.
Incorporation Directions
Soil Preparation and Incorporation
Ground cover or existing weeds can interfere with uniform soil incorporation of Sentry Trifluralin 4EC. A manageable level of
ground cover will allow uniform incorporation into the top 2 to 3 inches o f the final seedbed. Ground cover and crop residues, if
excessive, should be reduced by appropriate soil tillage prior to application.
Sentry Trifluralin 4EC must be incorporated within 24 hours after application unless otherwise specified on supplemental
labeling. Non-uniform appl ication 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 bef ore 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 a nd efficient
incorporation of Sentry Trifluralin 4EC. Break up clods using tillage eq uipment prior to application of Sentry Trifluralin 4EC. 
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 ex cessively moist.
Incorporation in Bedded Culture: In bedded culture, Sentry Trifluralin 4EC should be incorporated to a depth of 2 to 3 inches
in the final seedbed.
Application Prior to Bedding: Apply Sentry Trifluralin 4EC and incorporate one time with specified equipment. The bedding
operation serves as the second incor poration. Do not expose untreated so il 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 Sentry Trifluralin 4EC. Apply and incorporate
Sentry Trifluralin 4EC with specified equipment that will conform to the s hape of the bed. Do not expose untreated soil.
Cultivation After Planting: Treated crops may be shallowly cultivated without reducing the weed control activity of Sentry
Trifluralin 4EC. 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.

Page 11 of 45 
 
Incorporation Equipment
Use incorporation equipment capable of mixing Sentry Trifluralin 4EC uni formly into the top 2 to 3 inches of the final seedbed. 
Use of inappropriate equipment or improper use of specified equipment m ay result in erratic weed control and/or crop injury. 
Incorporation equipment such as a tandem disc will mix Sentry Trifluralin 4EC approximately half as deep as the equipment is
set to operate. For example, a disc set to cut 4 inches deep will mix most o f the Sentry Trifluralin 4EC within the top 2 inches
of soil. Any specified incorporation implement may be used alone or in combination with any other specified implement. Two
incorporation passes are required when using the following incorporation implements (for single pass incorporation, refer to soil
conditions and equipment listed under Si ngle 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 incorpo ration 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 3to 4 inchesdeep and operate at 5 to 8
mph.·
Other Equipment: Other implements including the flexible tine-tooth harrow (Flextine or M elroe) are specified, but only for
certain uses defined in the Crops section of this label.
Conservation Tillage Practices: In reduced or minimum tillage situations, fall or spring application and incorporation of
Sentry Trifluralin 4EC may be combined with tillage operations. The first incorporation may utilize equipment such as a
tandem disc, combination implement or bedding equipment that provides good 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 u niform
soil mixing used in conjunction with no-till planters (see specific ins tructions for reduced or conservation tillage situations for
cotton and soybeans in the Crops section).
Single Pass Incorporation Option
Sentry Trifluralin 4EC 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 incorp oration 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:
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, r eel, 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 le ss with sweeps on successive rows staggered so
that no soil is left unturned. 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 two or more tillage devices combined to operate as a single
tillage unit. For example, two to three rows of field cultivator C- or S-s haped 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 directed 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 t ools can also be composed of two 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 Sentry Trifluralin 4EC into the top 2 to 3 inches of the final seedbed.
P.T.O.-Driven Equipment (Tillers, Cultivators, Hoes): Adjust equipment to incorporate Sentry Trifluralin 4EC 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 Sentry Trifluralin 4EC to established alfalfa may be activated by rainfall, sprinkler,
flood, or furrow irrigation. Rainfall or a single overhead sprinkler irr igation of 0.5 acre inch or more is required to
activate Sentry Trifluralin 4EC. If activated by furrow irrigation, car e should be taken to thoroughly wet beds between
furrows. If rainfall or irrigation has not occurred within three days af ter application, SentryTrifluralin4EC maybe
mechanicallyincorporated. Ifmechanicallyincorporated, 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 d uring dormancy or semi- dormancy, or
during the growing season immediately after a cutting. Because Sentry Tr ifluralin 4EC does not control established
weeds, application 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 Sentry Trifluralin 4EC
immediately after a cutting between August 1and October 1, but prior to we ed germination. When fall applied, Sentry
Trifluralin 4EC controls bromegrass and cheat in addition to other labeled weeds that germinate after application.
The following weeds are controlled when Sentry Trifluralin 4EC is applied by chemigation or surface applied
and incorporated by rainfall or irrigation:
barnyardgrass
bromegrass

Precautions:
x Do not cut or graze alfalfa within 21 days after application of Sentry Trifluralin 4EC.
x Apply no more than 4 pints of Sentry Trifluralin 4EC during any growing sea son. In the growing season
following application of 4 pints of Sentry Trifluralin 4EC to alfalfa, plant only those crops for which Sentry
Trifluralin 4EC is registered as a preplant treatment or crop injury may occur.
Tank Mixing
Other products registered for use on established alfalfa may be applied in tank mix combination with
Sentry Trifluralin 4EC or applied as sequential treatments following application of Sentry Trifluralin 4EC.
Tank mixes containing Sentry Trifluralin 4EC must be applied by ground bro adcast when alfalfa is
dormant or semi-dormant, or immediately after a cutting.
Precautions: 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

Incorporation Directions
Applications of Sentry Trifluralin 4EC must be mechanically incorporat ed within 24 hours. Mechanical incorporation
may be accomplished with one 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, Sentry Trifluralin
4EC may be incorporated by continuous rainfall or sprinkler irrigation amounting to at least ½ to 1 inch of water. Best
results are obtained if application is made immediately after a cultivati on 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 movement of Sentry Trifluralin 4EC 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 desc ribed above if the required amount of
rainfall or sprinkler irrigation does not occur within 24 hours after application.

days before harvest.
Application Directions
Sentry Trifluralin 4EC may be applied and soil incorporated or it may be applied through chemigation (see
directions for chemigation in Chemigation section below).
Follow specified soil preparation, application, and incorporation pro cedures in the Product Information section of this
label. For fall application, in additi on to the directions below, refer to instructions in the Application Timing section
under Product Information. For layby application, refer to instructions in the Layby Application section below.
If incorporating after planting, incorporate Sentry Trifluralin 4EC soon after planting and set equipment so
as to avoid disturbing planted cottonseed.
For band applications, reduce the application rate in proportion to the row spacing and bandwidth treated. For
example, treating a 12-inch band where the row spacing is 36 inches would re quire 1/3 of the specified
broadcast rate per acre (12 inches divided by 36 inches = 1/3).
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 Sentry Trifluralin 4EC o r as a sequential treatment 
following application of Sentry Trifluralin 4EC. When tank mixing, use the specified rate ofSentry Trifluralin

Minimum Tillage Cotton (Conservation Tillage Cotton) Fall Applicatio n Prior to Establishing a Cover Crop
Apply Sentry Trifluralin 4EC to flat ground at a broadcast rate of 2 to 3 pint s per acre. Use the 3 pint per acre rate
where crop residues are present or where dense weed populations are antici pated. Incorporate once within 24
hours using incorporation implements, such as a springtooth harrow, set to cut no more than 2 to 3 inches deep. 
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 furrow area to the beds.
Fertilizer may be applied as appropriate during incorporation operation s. Plant 2 to 4 rows of a small
grain cover crop, such as barley, rye or wheat, 2 inches deep in the furrow area be tween the beds. To 
avoid injury to small grain seedlings, place seed below the treated layer of soil . Barley is more tolerant to
injury than wheat or rye. Existing soil moisture must be present to establish and maintain the cover crop. 
In late winter (February), apply 2,4-D if necessary for broadleaf weed control.
Spring Application Before or After Planting
Apply Sentry Trifluralin 4EC as a broadcast treatment or as a band to bare g round or standing dead
cover following burndown with a postemergence herbicide. Sentry Trifluralin 4EC may be applied and 
incorporated either before planting or after planting. If applied after p lanting, incorporate immediately and
set incorporation equipment to operate at a depth that will not disturb the planted seed. I f Sentry
Trifluralin 4EC is applied as a band, adapt incorporation equipment to the width of the t reated band and
use equipment that that will uniformly mix Sentry Trifluralin 4EC into the top 1 inch of soil. Be aware that
compared to double-pass incorporation, weed control may be reduced when u sing single pass 
incorporation; or, if using equipment that does not provide thorough soil mixing.

Chemigation
Apply Sentry Trifluralin 4EC in overhead sprinkler irrigation equal to 1 /2 to 1 inch of water in either
conventional or minimum tillage cotton. Sentry Trifluralin 4EC must be ap plied within two days after
planting and prior to crop emergence. Because Sentry Trifluralin 4EC do es not control established weeds,
planting and application should occur as soon as possible after the last tillage operation. Soil incorporation
is not required when Sentry Trifluralin 4EC is applied through chemigations y s t e m s .
Cultivation: Soil treated by chemigation with Sentry Trifluralin 4EC may be shallow cul tivated without
reducing weed control activity.
Refer to Application by Chemigation in the Product Information section of this label for use directions for

Rhizome johnsongrass control with Sentry Trifluralin 4EC requires maxim um application rates for two
consecutive years (see Broadcast Application Rates per Acre for Rhizome J ohnsongrass Control below).
Commercially acceptable control cannot be obtained with only one year of applying the maximum use
rate of Sentry Trifluralin 4EC. Carefully follow all special use direct ions.
Soil Preparation: Satisfactory results are dependent upon proper preparation of soil prior to application.
Chisel plow to bring rhizomes to the soil surface. Disc twice before appl ication to chop rhizomes into small
(2 to 3 inch) pieces and destroy any recently emerged johnsongrass plants.

Spring Application: Apply Sentry Trifluralin 4EC any time before planting in the spring for two years
in succession.
Fall Application: Apply Sentry Trifluralin 4EC between October 15 and December 31 for two yea rs in 
succession.
Incorporation: Deep incorporation with a tandem disc is essential for good results. Set d isc to
operate 4 to 6 inches deep and operate at 4 to 6 mph. Two incorporation passe s are necessary; the
second should be in a different direction than the first.
Cultivation: Some johnsongrass plants will not be controlled. Timely cultivation dur ing the crop season is 
necessary to remove escaped plants and maintain commercially acceptable control.
Precautions: In the season following a maximum rate treatment, plant only rice or crops f or which Sentry
Trifluralin 4EC is labeled as a preplant incorporated treatment, or crop injury may occur.
Restrictions and Use Precautions
Precautions: To avoid crop injury, cotton should be planted after early season adverse w eather conditions
have passed, especially when using high rates. Cool, wet weather early in the growth cycle causes stress
to the cotton plant. The added stress may result in reduced stand, delayed m aturity, and reduced yields.
Maximum Crop Year Use Rates: For full season weed control, Sentry Trifluralin 4EC may be applied one
or moretimes sequentially during the crop year observing the rates, methods of application, and a 90-day
preharvest interval. The maximum dosage must not exceed the rates given, and the maximum cumulative
amount of Sentry Trifluralin 4EC that may be applied within the same crop year (includes fall
application or spring application plus layby application) must not excee d 4 pints per acre (2 lb active
ingredient per acre).
Rotation Crop Restrictions: Refer to Rotation Crop Restrictions section under Product Information fo r
specific rotational crop restrictions. When the cumulative amount of Se ntry Trifluralin 4EC in one crop year
(fall or spring plus layby) exceeds the rates in the table below, plant only those crops for which Sentry
Trifluralin 4EC is labeled as a preplant incorporated treatment in the season following the application of
Sentry Trifluralin 4EC, or crop injury may result.

Small Grains – Barley, Durum and Wheat
Special Precautions for Use of Sentry Trifluralin 4EC on Small Grains
Carefully follow directions for use of Sentry Trifluralin 4EC on small gra ins to minimize potential crop stress. 
Under certain conditions, delayed crop emergence and or stand reduction m ay occur when Sentry Trifluralin
4EC is applied to barley, durum, or wheat. The combined effect of certain c ultural practices and unfavorable
soil or environmental conditions may cause excessive crop seedling stre ss 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.
Do not exceed specified application rates for Sentry Trifluralin 4EC. Thi s is particularly important on coarse
textured or low organic matter soils.
Carefully follow incorporation directions. When applying preplant inc orporated treatments, operate
equipment at specified depth and speed to place Sentry Trifluralin 4EC i nto the upper 1 to 1 1/2
inches of soil. If applied after planting, set incorporation equipment s o as to avoid disturbance of
planted seed.
Set drills to place seed at a the depth specified in use directions. A plan ting depth greater than 2
1/2 inches for spring wheat or durum will result in increased seedling stress and decreased
emergence.

Page 31 of 45 
 
 
Use only high quality seed where Sentry Trifluralin 4EC is to be applied (av oid 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 Sentry Trifluralin 4EC 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, droug ht, and soil
crusting from heavy rainfall.
Note: Do not apply Sentry Trifluralin 4EC on small grains where a dinitroaniline herbicide
such as Treflan or Sonalan® herbicide was applied at a rate greater than 0.5 lb ai per acre the
previous growing season.

2. Soybeans - Weed Control Under Reduced or Conservation Tillage
Sentry Trifluralin 4EC 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 one application per crop cycle.
Apply to tilled land or standing or chopped stubble from the previous seaso n's crop. The first 
incorporation of Sentry Trifluralin 4EC must occur within 24 hours. For t he first incorporation, a
tandem disc or combination tool that can thoroughly mix Sentry Triflural in 4EC into the top 2 to 3
inches of the final seedbed while leaving the desired amount of plant residue on the soil sur face
is specified. 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 Sentry Trifluralin 4EC ma y be applied as a preplant
incorporated treatment. See instructions for Application with Dry Bulk Fertilizer in the Product
Information section of this label. Under reduced or conservation tillage conditions, uniformly applied
dry bulk fertilizers impregnated with Sentry Trifluralin 4EC provide weed and grass control e qual to

6. Soybeans - Charcoal Soils in Arkansas, Louisiana, and Mississippi
Newly cleared land often contains high organic matter (5 to 10%) and charco al from burning
debris. Charcoal and organic matter tends to bind Sentry Trifluralin 4EC and reduce weed
control activity. Under these conditions, higher rates of Sentry Trifluralin 4EC are necessary fo r
weed control. Increased rates, however, can cause crop injury if charcoa lo ro r g a n i cm a t t e ri s 
not present to bind some of the Sentry Trifluralin 4EC. In the burn row a hi gh level of charcoal
is usually present. Consequently, poor weed control may result, even if an increased rate of
Sentry Trifluralin 4EC is used. Follow specified application and incorporation procedures for
Sentry Trifluralin 4EC.

commercially acceptable control. Commercially acceptable control can not be obtained with only a
single year use of Sentry Trifluralin 4EC.
Precautions: Do not use the 4 pint rate on new plantings or crop injury may result. Do not i nterplant
orchards or vineyards with other crops. If treated vineyards and orchard s are diverted to other crop
uses, then in the next cropping season plant only those crops for which Sentry Tr ifluralin 4EC has
been registered as a preplant incorporated treatment.

soil tillage before applying Sentry Trifluralin 4EC to prevent interference with operation of the spray
blade.
Equipment: Application requires a spray blade capable of operation at 4 to 6 inches bel ow the soil
surface. The blade should be equipped with nozzles located under the blad e and directed so as to

Precautions: Some soils may develop cracks as they dry after rainfall or irrigation. F ield bindweed
may emerge if the cracks extend through the layer of Sentry Trifluralin 4EC. Prevent or eliminate
cracks by shallow discing or other tillage. Avoid deep tillage which disturbs the s ubsurface layer.
Cultivation or tillage also aids the control of germinating seeds.
