GENERAL INFORMATION
MIXING: When using Sencor® DF, make sure the sprayer is completely clean, free of rust or corrosion which occurs from winter
storage. Examine strainers and screens to be sure the sprayer is clean from previously used pesticides.
Any tank mix containing Sencor® DF should be kept agitated and sprayed out immediately. Do not allow tank mixes to stand for
prolonged periods of time.
The proper mixing procedure for Sencor® DF alone or in tank mix combinations with other herbicides is:
1. Fill the spray tank 1/4 to 1/3 full with clean water. •
2. Add recommended rate of Sencor® DF while recirculating and with agitator running.
3. Follow the triple rinse procedure described under "STORAGE AND DISPOSAL" to insure that all product is removed from the
container.
4. Mix thoroughly and add clean water to fill spray tank to desired level.
5. Add the other herbicide to tank last and agitate thoroughly.
6. Continue agitation during application and until sprayer tank is empty.
SOIL TEXTURE: As used on this label, "Coarse soils" are loamy sand or sandy loam soils. "Medium soils" are loam, silt loam, silt,
sandy clay, or sandy clay loam. "Fine soils" are silty clay, silty clay loam, clay, or clay loam. Silty clay loam soils are transitional soils
and may be classified as medium-textured soils in some regions of the U.S.
GENERAL PRECAUTIONS AND RESTRICTIONS
• Do not allow sprays to drift on to adjacent desirable plants.
• Apply this product only as specified on this label.
• Do not use on other crops grown for food or forage. Observe all cautions and limitations on labeling of all products used in mixtures.
• Do not rotate any crop not listed on this label for 18 months following application of Sencor DF.
• For all uses: Low-pressure and high-volume hand-wand equipment is prohibited.
CHEMIGATION
Sencor® DF is recommended for application through sprinkler irrigation equipment to potatoes, soybeans, tomatoes, and asparagus as
directed on this label. Refer to the crop sections of this label for recommended rates, weeds controlled or suppressed, restrictions, and
special precautions.
Apply this product only through sprinkler (including center pivot, lateral move, or solid set) irrigation systems. Do not apply this product
through any other type of irrigation system.
Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from nonuniform distribution of treated water.
Calibration: (Center Pivot and Self-Propelled Lateral Move Systems): Sprinkler irrigation systems must be accurately calibrated for
application of Sencor® DF. Greater accuracy in calibration (and distribution) will be achieved by injecting a larger volume of a more
dilute mixture of product and water per hour. Follow the steps below to calibrate center p'ivot and lateral move systems:
1. Determine number of minutes required to make one complete revolution while applying 1/4 to 3/4 inch of water per acre.
2. With the system at operating pressure determine the exact number of minutes required to inject one gallon of water.
3. Divide the time required for one revolution (step 1) by the time required to inject one gallon (step 2). This gives total gallons of
product-water mixture to be added to nurse tank.
4. Add required amount of water to nurse tank and start the agitation system. Then add sufficient Sencor® DF at the recommended
rate (See RECOMMENDED BROADCAST APPLICATIONS) to the nurse tank.
EXAMPLE: If 20 hours (1200 minutes) were required for one revolution and if 2 minutes were required to inject one gallon, then a total
of 600 gallons of product-water mixture are required (1200/2 = 600); to treat 135 acres at 2/3 Ib/acre, 90.5 Ib of Sencor® DF are
required.
If you have questions about calibration, you should contact State Extension Service Specialists, equipment manufacturers or other
experts.
Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system unless the
pesticide label-prescribed safety devices for public water systems are in place.
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.
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 backflow.
The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back toward
the injection pump.
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.
The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump
motor stops.
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 where pesticide distribution is adversely affected.
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.
Do not apply when wind speed favors drift beyond the area intended for treatment.
Maintain continuous agitation in the injection nurse tanks during the herbicide application, sufficient to keep herbicide in suspension.
Apply specified dosage in 1/4 to 3/4 inch of water (1/4 to 1/2 inch of water on sandy soils) per acre as a continuous injection in center
pivot and lateral move systems or in the last 15 to 30 minutes of set in permanent solid set sprinkler systems. Application of more than
the quantity of irrigation water recommended on this label may result in decreased product performance by removing the chemical from
the zone of effectiveness. Where sprinkler distribution patterns do not overlap sufficiently unacceptable weed control may result.
Where sprinkler distribution patterns overlap excessively crop injury may result. Allow sufficient time for pesticide to be flushed through
all lines and all nozzles before turning off irrigation water. To ensure that lines are flushed and free of remaining pesticide, an indicator
dye may be injected into the lines to mark the end of the application period.
Use a minimum of 1 part water to 1 part herbicide for injection. The use of a larger volume of water will insure greater accuracy and
more uniform distribution.
AERIAL DRIFT REDUCTION ADVISORY INFORMATION
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 spray drift. The applicator and the grower are responsible for considering all these factors when
making decisions.
The following drift management requirements must be followed to avoid off-target drift movement from aerial applications to agricultural
field crops. These requirements do not apply to forestry applications, public health uses or to applications using dry formulations.
1 The distance of the outer most nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor.
2.Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees.
3.Where states have more stringent regulations, they should be observed.
4.The applicator should be familiar with and take into account the information covered in the Aerial Drift Reduction Advisory Information.
INFORMATION ON DROPLET SIZE: The most effective way to reduce drift potential is to apply large droplets. The best drift
management strategy is to apply the largest 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 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 many nozzle types lower pressure produces
larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure.
• Number of nozzles - 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 practice. Significant deflection from horizontal will reduce droplet size and increase drift
potential.
• 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 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 downwind. 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, many 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 familiar with local wind patterns 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 can be indicated by ground fog; however, if fog is not
present, inversions can also be identified by the movement of smoke from a ground source or an aircraft smoke generator. Smoke that
layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward
and rapidly dissipates indicates good vertical air mixing.
SENSITIVE AREAS: Sencor® DF should only be applied when the potential for drift to adjacent sensitive areas (e.g. residential areas,
bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal (e.g. when wind is blowing away
from the sensitive areas).
APPLICATION OF SENCOR® DF WITH HERBICIDE SPRAY EQUIPMENT
Use a standard low-pressure (20 to 40 psi.) herbicide boom sprayer equipped with suitable nozzles and screens no finer than 50-mesh
in-nozzle and in-line strainers. Agitate thoroughly before and during application with bypass agitation.
GROUND APPLICATION: Apply the proper rate of Sencor® DF in a minimum of 10 to 40 gallons of spray mixture per acre broadcast.
Banded Application: Use proportionally less Sencor® DF per acre in a band versus a broadcast application. For band application use
1/4 to 1 gallon of spray mix per inch of band width regardless of row spacing.
EXAMPLES: (1) To treat a 15-inch band on rows 30 inches apart, use one-half of the broadcast rate of Sencor®. (2) To treat a 14-inch
band on rows 42 inches apart, use one-third of the broadcast rate of Sencor®.
AERIAL APPLICATION: Where permitted, apply specified rate in a minimum of 2 to 10 gallons of spray mixture per acre. Do not apply
aerially when wind speed is greater than 10 mph.
NOTE: Do not apply aerially when Sencor® is tank mixed with Lasso®.
For All Applications of Sencor® DF: Sprayer must be accurately calibrated before applying Sencor® DF. Check sprayer during
application to be sure it is working properly and delivering a uniform spray pattern. As the volume of spray mixture decreases per acre,
the importance of accurate calibration and uniform application increases. Avoid over application, misapplication, and boom and spray
swath overlapping that will increase spray dosage. (Crop injury may occur as a result). Avoid spray skips and gaps which allow weeds
to grow in untreated soil. Do not apply when weather conditions favor spray drift and/or when sensitive or cool season crops, such as
cole crops, onions, peas, or strawberries are present in adjacent fields or in areas where wheat is growing in coarse textured soils.
SPRAYER CLEANUP: Spray equipment must be thoroughly cleaned to remove remaining traces of herbicide that might injure other
crops to be sprayed. Drain any remaining spray solution of Sencor® from the spray tank and dispose of according to label disposal
instructions. Rinse the spray tank and refill with water, adding a heavy-duty detergent at the rate of one cup per 20 gallons of water.
Recycle this mixture through the equipment for 5 minutes and spray out. Repeat this procedure twice. Fill the spray tank with clean
water, recycle for 5 minutes, and spray out. Clean pump and nozzle screens thoroughly. Wash away any spray mixture from the
outside of spray tank, nozzles or spray rig. All rinse water must be disposed of in compliance with local, state, and Federal guidelines.
APPLICATION OF SENCOR® DF IN FLUID FERTILIZERS
Sencor® DF may be applied in fluid fertilizer solutions to alfalfa and soybeans by following the appropriate mixing procedures and
compatibility check. When using tank mix combinations, be sure all components are compatible.
Compatibility checks of Sencor® DF and tank mix combinations which include Sencor® should be made for each batch of fluid fertilizer
because of the variability of these fertilizers.
Compatibility Check'.
1. Pre-mix 2 teaspoonfuls of Sencor® DF with 8 teaspoonfuls of water (1:4 ratio) in a quart jar by adding the water first and follow with
Sencor® DF. Mix thoroughly. If a second herbicide is to be used, double the amount of water (1:8 ratio) and add the second'
herbicide after mixing Sencor® DF first.
2. Then pour 1 pint of fluid fertilizer into the quart jar and shake well.
3. Allow to stand for 5 minutes.
THIS COMPATIBILITY CHECK SHOULD ONLY BE USED WHEN MIXING WITH FLUID FERTILIZERS.
Interpretation of Results: If the solution in the jar appears to be uniform, without signs of agglomeration, or without a separation of an
oily film on top of the fertilizer, the mixture may be used. If not, repeat the compatibility check using twice the amount of water or add a
compatibility agent to the water. If separation occurs, but the mixture can be resuspended by shaking, then application is possible with
good agitation in the spray tank.
Tank mixing Guidelines:
1. Add the required amount of water and compatibility agent (if required) to the tank. Start agitation system while adding Sencor® DF
and follow by adding the fluid fertilizer and agitate.
2. If a second herbicide is to be used, follow as above in 1, but use twice the amount of water. Start agitation and add Sencor® DF
and follow by adding the second herbicide, and then continue filling the tank with fluid fertilizer.
3. Maintain continuous agitation to assure uniform spray mixture until the tank is emptied.
COMMERCIAL IMPREGNATION AND APPLICATION OF SENCOR® DF ON DRY BULK FERTILIZER
Dry bulk fertilizer may be impregnated or coated with Sencor® DF for application to established alfalfa and to soybeans. All
recommendations, cautions, and special precautions on this label must be followed along with state regulations relating to dry bulk
fertilizer blending, impregnating and labeling.
Impregnation: To impregnate, use a system consisting of a belt, conveyor, or closed drum which is used for dry bulk fertilizer blending.
Any commonly used fertilizer can be impregnated with Sencor® except ammonium nitrate, or fertilizers containing ammonium nitrate,
potassium nitrate, or sodium nitrate. Do not use on powder limestone.
Apply using a minimum of 200 Ib dry bulk fertilizer per acre and up to a maximum of 450 Ib per acre. To impregnate or coat dry bulk
fertilizer, mix Sencor® DF with sufficient water to form a sprayable slurry. The delivery nozzles must be directed to deliver a fine spray
toward the fertilizer for thorough coverage while avoiding spray contact with mixing equipment. Uniform impregnation of Sencor® DFto
dry bulk fertilizer will vary and if the absorptivity is not adequate, an absorptive powder may be added to produce a dry, free-flowing
mixture. Micro-Cel E (Johns-Manville Product Corporation) is the recommended absorbent powder. When another herbicide is used
with Sencor® DF, mix and impregnate immediately.
Apply immediately after impregnation unless experience has shown that impregnated fertilizer can be stored without becoming lumpy
and difficult to spread.
Rates: Select the recommended rate of Sencor® DF per acre from the appropriate section of this label and refer to the formula below to
determine the amount of Sencor® DF which is to be impregnated on a ton of dry bulk fertilizer based on the amount of fertilizer which
will be distributed on one acre.
Lb Sencor® DF X 2000 Lb Fertilizer = Lb Sencor® DF
Acre Acre Ton of Fertilizer
Application: Uniform application is essential for satisfactory weed control. Accurate calibration of fertilizer application equipment is
essential for uniform distribution to the soil surface. The recommended method of application is to apply 1/2 the recommended rate and
overlap 50 percent or to double apply by splitting the middles to obtain the best distribution pattern.
If fertilizer materials are excessively dusty, use diesel oil or other suitable additive to reduce dust prior to impregnation as dusty fertilizer
will result in poor distribution during application. Crop injury and/or poor weed control may occur where the impregnated fertilizer is not
uniformly applied.
INCORPORATION AND COMBINATION USES: When Sencor® DF is to be used in combination with another herbicide, follow
directions on this label for combinations, rates, crops, incorporation, and special precautions.
SOYBEANS
(EXCEPT CALIFORNIA)
Sencor® DF herbicide tank mix combinations are recommended for preplant incorporated applications, preemergence surface
applications, Split-Shot application and Extended Split-Shot application. Sencor® DF is also recommended as an overlay application
following a preplant incorporated application of a recommended grass herbicide and alone as a preemergence surface application. All
these applications can be applied with ground equipment, and some can be applied with aerial spray equipment. In addition, Sencor®
DF can be applied as a postemergence directed spray to soybeans in certain states.
SPECIAL PRECAUTIONS (Soybeans): Injury to soybeans may occur when Sencor® DF is used under the following conditions:
• When soils have a calcareous surface area or a pH of 7.5 or higher.
• Due to the sensitivity of certain soybean varieties, Sencor® DF is not recommended for use on Altona, AP 55, AP 71, Asgrow
6520, Burlison, Coker 102, Coker 156, Dassel, GL 3202, Govan, Maple Amber, NB 3665, NKS 1884, Paloma 350, Portage,
Regal, Semmes, Terra-Vig 505, Terra-Vig 606, Tracy, Vansoy, and Vinton 81. Consult your Bayer CropScience Representative
6
or your seed supplier for information on the tolerance to Sencor® of newly released soybean varieties, prior to use of Sencor®
DF.
• When applied in conjunction with soil-applied organic phosphate pesticides.
• Over application or boom overlapping may result in stand loss and soil residues.
• Uneven application or improper incorporation can decrease the level of weed control and/or increase the level of injury.
• When applied to any soil with less than 1/2% organic matter.
• Soil incorporation deeper than recommended.
• When sprayers are not calibrated accurately.
• When heavy rains occur soon after application, especially in poorly drained areas where water may stand for several days.
• When soybeans are planted less than 1-1/2 inches deep, particularly in preemergence application.
Activation: A minimum amount of soil moisture is required to activate Sencor® DF. In areas of low rainfall, preemergence applications
to dry soil should be followed with light irrigation of 1/4 acre inch of water. Do not apply heavy irrigation immediately after application.
As with many surface-applied herbicides, weed control and crop tolerance may vary with rainfall and/or soil texture.
Grazing and Feeding Treated Vines: Treated vines may be grazed or fed to livestock 40 days after application when Sencor® DF is
applied alone or with Treflan®, Dual®, Prowl®, or Lasso®.
Do not use treated vines for feed or forage when Sencor® DF is applied with Sonalan®, linuron plus Lasso®, or linuron plus Dual®.
Rate Ranges: Where a rate range is shown, use a lower rate on soils that are coarse-textured or low in organic matter. Use a higher
rate on soils that are relatively fine-textured or high in organic matter.
Replanting: If replanting is necessary in fields treated with Sencor® DF as directed on this label, the field may be replanted to
soybeans. When replanting a minimum of tillage is recommended. Do not apply a second treatment as injury to soybeans may occur.

1 For control of lambsquarters, redroot pigweed and wild mustard, and for suppression of green, yellow and giant foxtails on alkaline (calcareous) soils in
Nebraska, Minnesota, South Dakota and North Dakota only, apply Sencor® DF at rates of 1/3 Ib/acre on medium soils and 1/3 to 1/2 Ib/acre on fine
soils regardless of soil organic matter percentage (use 1/2 Ib only where soil pH is less than 7.5 and weed pressure is heavy). The 1/3 Ib/acre rate of
Sencor® DF alone can be applied regardless of soil pH. For control of other weeds listed on this label use Sencor® DF at full rates recommended in
the table above, but note that crop injury may occur on soils having a calcareous surface area or a pH of 7.5 or higher.
2 Silty clay loam soils are transitional soils and may be classified as medium textured soils in some regions of the U.S.
3 Refer to the appropriate section of this label for use of Sencor® DF on soybeans in coarse soils with 0.5% or more organic matter in certain states.
USES OF SENCOR® DF HERBICIDE IN COMBINATION WITH OTHER HERBICIDES
SEQUENTIAL APPLICATION OF SCEPTER® FOLLOWING SENCOR® DF
If needed, application of Sencor® DF alone or in a registered tank mix according to directions on this label may be followed by an early
postemergence application of Scepter® herbicide (1.5 Ib/gal liquid or 70 DG) for control of cocklebur. Apply 1/6 to 1/3 pint of Scepter®
(0.7 to 1.4 ounces of Scepter® 70 DG) in a minimum of 20 gallons of water per acre. Use 1/6 pint of Scepter® (0.7 ounce of Scepter®
70 DG) if cockleburs are less than 3 inches tall or have fewer than 3 leaves and are actively growing. For cockleburs less than 6 inches
tall and actively growing use 1/3 pint of Scepter® (1.4 ounces of Scepter® 70 DG) per acre. Do not use Scepter® when soybeans or
cockleburs have been subjected to stress conditions such as temperature or moisture extremes. Do not exceed a total of 2/3 pint of
Scepter® (2.8 ounces of Scepter® 70 DG) per acre in one season. Wait at least 10 days after application of Scepter® before
cultivating.
When preparing the spray mixture with Scepter®, add 2 pt of nonionic surfactant approved for use on growing crops and containing at
least 80% active ingredient per 100 gallons of mixture. Apply crop oil concentrate (COC) at the rate specified on the COC label.
Use Scepter® only in the states where it is registered as listed on the product label.
Apply Scepter at least 90 days before harvest of soybeans. Do not graze or feed soybean forage, hay, or straw to livestock.
Refer to the Scepter® label for additional cautions and precautions, directions, limitations, and information on environmental hazards
and planting of rotational crops.
SPLIT-SHOT APPLICATION
A preplant incorporated application of Sencor® DF tank mixed with either Treflan®, Lasso®, Dual®, Prowl® or Sonalan® and followed
by a preemergence surface application of Sencor® DF alone after planting but prior to soybean emergence, will control more broadleaf
and grass weeds in soybeans than when either herbicide is used alone.
Refer to the Treflan®, Lasso®, Dual®, Prowl® or Sonalan® labels, and to appropriate sections of this label for directions on soil
preparation, herbicide application, incorporation techniques, herbicide rates, weed species controlled, and restrictions for using tank mix
combinations of Sencor® DF. Carefully observe the "Special Precautions" section concerning the use of Sencor® DF in tank mix
combinations on soybeans.
When a Split-Shot application of Sencor® DF with Prowl®, Treflan®, or Sonalan® is used, the preplant incorporated tank mix may be
applied up to 21 days prior to planting soybeans; with Dual® or Lasso®, the preplant incorporated tank mix may be applied up to 14
days prior to planting.
On medium and fine textured soils with greater than 2% organic matter, a rate range is recommended for the Sencor® DF
preemergence overlay application. The higher rate should be used (a) in fields with a history of severe broadleaf weed pressure, (b)
when the time between preplant incorporated tank mix and preemergence overlay applications approaches the maximum stated above,
and/or (c) when the organic matter content of the soil is at the upper end of the indicated range.
For black nightshade control, refer to the appropriate sections of the Lasso®, Dual®, or Sonalan® labels for specific instructions.

* Silty clay loam soils are transitional soils and may be classified as medium textured soils in some regions of the U.S.
1 On coarse textured soils, does not use on sand soils with less than 1% organic matter, or on loamy sand or sandy loam soils with less than 0.5%
organic matter. However, on coarse textured soils with a calcareous surface area or a pH of 7.5 or higher, do not use on sand soils with less than
2% organic matter, or on loamy sand or sandy loam soils with less than 1% organic matter.
2 Use this lower rate of Sencor® DF in the preplan! ncorporated tank mix on soils having a calcareous surface area or a pH of 7.5 or higher, and
in those situations where soils within a field vary extremely in texture or organic matter content.
3 Reduce this preemergence overlay rate of Sencor® DF by 1/6 Ib/acre when using SPLIT-SHOT application on soils with over 4% organic matter
and which have a calcareous surface area or a pH of 7.5 or higher.
EXTENDED SPLIT-SHOT APPLICATION
(Includes No-Till, Reduced-Till, Ridge-Till, Strip-Till, Mulch-Till)
An early preplant (surface-applied or shallow incorporated) application of Sencor® DF tank mixed with either Dual® or Lasso®,
followed by a preemergence surface application of Sencor® DF tank mixed with Dual® or Lasso® after planting but prior to soybean
emergence, will control more broadleaf and grass weeds in soybeans than either herbicide used alone.
An Extended SPLIT-SHOT application will decrease the need for tillage and/or contact herbicides for the control of existing vegetation
prior to planting, while providing residual control of weeds after planting.
When an Extended SPLIT-SHOT application of Sencor® DF with Dual® or Lasso® is used, the preplant tank mix combination may be
applied 15 to 30 days prior to planting soybeans. Follow directions on the label accompanying the product for SPLIT-SHOT
applications from 0 to 14 days before planting.
Where a rate range is recommended, the higher rates should be used (a) in fields with a history of severe weed pressure, (b) when the
time between early preplant tank mix and preemergence overlay applications approaches the maximum 30 days, (c) when the organic
matter content of the soil is at the upper end of the indicated range, (d) when heavy crop residues are present on the soil surface,
and/or (e) when the early preplant tank mix application is shallow incorporated (e.g. use 2 to 2-1/2 qt Lasso® in the early preplant tank
mix when surface applied and use 2-1/2 to 3 qt Lasso® when the tank mix is to be lightly incorporated).
When weeds exceed 1 to 1-1/2 inches in height or diameter at application, use a contact herbicide, such as Round-Up® or
Gramoxone®.
Refer to the Dual® or Lasso® label, and to appropriate sections of this label for additional information on soil preparation, herbicide
application, weeds controlled, precautions, restrictions, limitations and sprayer clean-up..

Apply proper dosage using 10 to 40 gallons of water per acre as a directed spray in a 6 to 8 inch band on each side of the row after soybeans are 8
inches tall and before broadleaf weeds are 3 inches tall and before grasses and common ragweed are 1 inch tall. For best results the spray must cover
weed foliage with minimum or no contact with soybean foliage. Add a nonionic surfactant such as Ortho X-77 to the spray mixture to obtain better
wetting of weed leaf surfaces. To determine the correct dosage of Sencor® DF for a band application see "Banded Application" under the "General
Information" section in the front of this label.
If necessary, a second postemergence directed spray application can be made after 7 days.
Do not feed or graze green soybean vines. Do not harvest soybeans or use dry soybean vines for feed or forage within 70 days of last application.
SPECIAL PRECAUTIONS (Directed Postemergence):
• Do not apply directly to soybeans or serious crop injury will occur. Do not allow spray to contact more than the lower 1/4 to 1/3 of
soybean plants. Soybean leaves contacted by the spray will be.killed. .
• Do not apply Sencor® DF postemergence to sensitive soybean varieties. See "Special Precautions" in the front of this label.
• To avoid injury to other crops or desirable plants from spray drift, sprayer pressure must not exceed 30 psi and the sprayer must
be fitted with nozzles no smaller than 8002 T-Jet (or equivalent). Do not apply under weather conditions which favor drift.
POTATOES
Sencor® DF herbicide is recommended for use in ground, aircraft or specified chemigation equipment as a preemergence and/or
postemergence application to potatoes. Early maturing smooth skinned white and all red skinned varieties may be injured with
postemergence applications. The varieties Atlantic, Bellchip, Centennial, Chipbelle and Shepody are sensitive to Sencor® DF. Avoid
postemergence applications on these varieties. Preemergence applications on these varieties may cause crop injury under adverse
weather conditions, on coarse soils, under high soil pH, with higher rates per acre and with mechanical incorporation.
Ground Application: Sencor® DF is recommended for use with ground spray equipment applied as a preemergence and/or
postemergence application for control of the listed grass and broadleaf weeds in potatoes. Apply as a uniform broadcast spray at 20 or
more gallons per acre.
Aerial Application: Sencor® DF may be applied in aerial spray equipment as a preemergence and/or postemergence application at 5
or more gallons per acre.
Chemigation: Sencor® DF may be applied preemergence and/or early postemergence to potatoes using center pivot, solid set and
lateral roll systems. Apply specified dosage in 1/4 to 3/4 inch of water per acre (1/4 to 1/2 inch on sandy soil) as a continuous injection
in self-propelled systems or apply in the last 15 to 30 minutes of the set in other systems. Be sure all the Sencor® DF has been flushed
from the lines before shutting down the system.
WEEDS CONTROLLED: Sencor® DF applied to potatoes according to directions, will provide economic control of the following weeds. For optimum
control, applications should be made before weeds are 1 inch tall. (See NOTE)

SENCOR® DF
1/2 to 2/3
Apply specified dosage by aerial or ground spray equipment in 7 to 40 gallons of water per acre. Treat established alfalfa stubble after fall or winter
sheep grazing or green-chop harvest and prior to the time regrowth is 2" tall. Alfalfa foliage present at time of application can exhibit yellowing. Injury
may occur to alfalfa in areas of high salt concentration where the crop is stunted and/or has a poorly developed root system, or if alfalfa is under
stressed growing conditions such as diseases, insect infestations, or drought. For most effective postemergence weed control, treatment should be
made before weeds are 2" tall or before leaf rosettes are 2" wide. For maximum control, rainfall (1/4" or more) or irrigation is necessary within 30 days
of treatment, however, do not flood irrigate within 2 days after treatment. Use 1/2 Ib Sencor® on sand soil when only mustard, goosefoot,
lambsquarters, or canary grass are the weeds to be controlled. Do not apply earlier than 6 months after seeding. Do not graze or harvest within 28
days after application.
SPECIAL PRECAUTIONS:
• Maintain continuous mechanical agitation in the spray tank to insure a uniform spray mixture.
• Do not apply with aerial spray equipment when wind speed is greater than 10 mph. Do not apply when weather conditions favor
spray drift and/or when sensitive cool season crops, such as cole crops, onions, peas or strawberries, are present in adjacent
fields. Applications should not be made when weather conditions favor drift especially in areas where wheat is growing on coarse
textured soils in adjacent fields, or injury may occur.

FIELD CORN
POSTEMERGENCE APPLICATION
Sencor® DF is recommended for control of selected broadleaf weeds when applied as a tank mix combination with certain broadleaf
herbicides presently registered and recommended for postemergence use in field corn. Herbicides which may be tank mixed with
Sencor® DF include:
2,4-D®
Atrazine®
Banvel®
Basagran®
Buctril/Buctril Gel®
Buctril + atrazine (Premix)®
Clarity®
LaddokS-12®
Marksman®
Pursuit®*
Resource®
Scorpion III®
Tough®
* .Use only on Pursuit resistant/tolerant corn hybrids (IMI- Corn).
APPLICATION: Sencor® DF may be applied to field corn after crop emergence until just prior to tasseling. Broadcast applications may
be made with ground or aerial equipment. For optimum weed control, apply treatments when weeds are small and actively growing, but
before reaching the maximum heights listed in the Weeds Controlled table.
44
POSTEMERGENCE BROADCAST APPLICATION
Ground Application: Adjust nozzle height above crop and weed canopy to ensure uniform spray coverage. Gallonage should be
increased with increasing weed size and population density.
For tank mixes of Sencor® DF plus atrazine, Basagran®, Laddok® S-12, Buctril®, Buctril® + atrazine, Pursuit®, Resource®, Tough®,
or 2,4-D® arnine formulations, use flat fan nozzles spaced a maximum of 20 inches apart. Best results are achieved using a minimum
spray volume of 10 gallons per acre and spray pressure from 20 to 40 psi.
For Sencor® DF tank mixes with Banvel®, Clarity®, Marksman®, or 2,4-D® low volatile ester formulations, use drift-reducing nozzles
which are specifically designed to produce coarse sprays and reduce the amount of driftable fines. Additional measures which will help
avoid potential drift to sensitive crops and plants include using a minimum spray volume of 20 gallons per acre and keeping spray
pressures at or below 20 psi unless otherwise specified by the nozzle manufacturer.
For further precautions and additional instructions and recommendations, consult the tank mix partner's label.
Aerial Application: Apply in a minimum spray volume of 3 gallons per acre. For optimum spray coverage and distribution, use a
minimum of 5 gallons per acre and a maximum pressure of 40 psi. Use a boom and nozzle configuration which will provide a uniform
deposition pattern and coverage with low drift potential. Avoid overlaps to prevent potential crop injury. Do not apply near sensitive
crops or sensitive plants growing near the treated area. Do not apply when wind speed is greater than 10 mph or when winds are
moving toward sensitive crops or plants. To avoid drift hazards, applicator must follow the most restrictive labeling of the products used
in a tank mix. Refer to the appropriate tankmix partner's label for further precautions and recommendations.
POST DIRECTED APPLICATION
Sencor® DF in tank mix combinations with Banvel®, 2,4-D®, Buctril® or Scorpion® III may be applied post directed to field corn. Use
drop nozzles and appropriate spacing to direct spray below the corn whorl and upper leaves. The top of the target weed canopy must
be sufficiently below the whorl and upper leaves of the crop to permit this application and provide adequate spray coverage. The height
differential required between the crop and weed canopy will depend on the specific equipment used. Apply before tassel emergence.
For further precautions and additional recommendations, refer to the appropriate tank mix partner's label.
ADJUVANTS
The adjuvant types listed below may be utilized with certain Sencor® DF tank mix combinations. Consult the tank mix
recommendations section for the appropriate adjuvant and rate. Use of non-recommended adjuvants or rates may result in severe leaf
burn, crop stunting, and/or stand reduction. Use only adjuvants which are exempt from tolerance requirements under 40 CFR 180.1-
001.
DAN (urea ammonium nitrate) is commonly referred to as 28, 30, or 32% N.
Ammonium sulfate (spray grade) may be used as an alternative to UAN with certain tank mix combinations.
Non-ionic surfactants should contain at least 80% active ingredient.
DO NOT USE crop oil concentrate (COC) or any adjuvant containing vegetable or petroleum oils with any Sencor® DF tank mixtures as
severe leaf burn, crop stunting, and/or stand reduction may occur.
RAINFASTNESS
Sencor® DF will not reduce rainfastness of the recommended tank mix partners. Refer to the individual product labels for rainfastness
recommendations.
SPRAYER CLEANUP
Refer to each tank mix partner's label and the Sprayer Cleanup section of the Sencor® DF label for specific instructions on cleaning
spray equipment. Special attention should be given to the required cleanup procedures for 2,4-D®, Banvel®, Clarity®, and
Marksman®.
SPECIAL PRECAUTIONS
• Do not use on corn grown for seed, sweet corn, popcorn, or white corn.
• Do not apply more than 0.25 pounds a.i. metribuzin (5-1/3 ounces Sencor® DF) per acre per use season.
• Do not apply when field corn is under stress (see Stress statement below).
• Do not use aerial applications if sensitive crops or plants are growing in the vicinity of the area to be treated.
• Do not allow spray drift onto sensitive crops or plants.
• Do not use on sand, loamy sand or sandy loam soils that have less than 0.5% organic matter.
• Do not use on sand or loamy sand soils in Washington, Oregon or Idaho or crop injury may occur.
• Observe all precautions and limitations on labeling of all products used in the tank mixtures.
Stress is any condition or combination of conditions which impairs normal crop growth. Weather, disease, insect damage, fertility or
other factors may cause stress. Applications made before or after the corn is under stress from these factors or from periods of
prolonged cool, wet and cloudy weather or widely fluctuating day and nighttime temperatures, may result in temporary leaf burn,
yellowing and/or stunting of the crop. Recovery from damage is generally rapid with no lasting effects on new growth. Under extreme
stress, stand reductions may occur.
Feeding Restrictions: Field corn treated with Sencor® DF may be grazed or harvested for silage or grain 60 days after treatment.
Follow the most restrictive preharvest interval on the labels of the products used in the tank mixtures.

DIRECTIONS AND REMARKS*
Apply as a broadcast spray during the interval from corn emergence until corn is 8 inches tall. Apply only to
varieties known to be tolerant to 2,4-D. DO NOT USE ADJUVANTS. 2,4-D may cause injury to nearby sensitive
crops. 2,4-D applications may result in brittle corn stalks, and winds or cultivation may cause stalk breakage. To
reduce damage, delay cultivation 8 to 10 days after application.
Apply as a broadcast spray during the interval from corn emergence until corn is 12 inches tall. A non-ionic
surfactant (1 qt/100 gal of spray solution) may be added to improve weed control. Atrazine is a restricted use
herbicide. Follow all state and federal label recommendations and restrictions pertaining to atrazine applications.
Apply as a broadcast spray during the interval from corn emergence through the five leaf stage or when corn is 8
inches tall, whichever occurs first. For Banvel applications to corn greater than 8 inches in height, consult the
Banvel label for use rates and restrictions. If growing conditions are dry and plants are stressed, addition of a non-
ionic surfactant (1 qt/100 gal of spray solution) may improve weed control. For corn grown on coarse textured soils,
apply Banvel or Clarity at 0.5 pt/A, regardless of application method. Application may cause injury'to nearby
sensitive crops or plants. Application may result in temporary leaning of corn plants. Delay cultivation until plants
return to normal growth patterns to avoid stalk breakage.
Apply as a broadcast spray after corn emergence but before corn exceeds 30 inches in height and the crop canopy
closes the row. Adjuvants such as UAN (0.5 to 1 gal/A), ammonium sulfate (17 lbs/100 gal of spray solution), or
non-ionic surfactant (1 qt/100 gal of spray solution) may improve weed control.
Apply as a broadcast spray when corn is in the fourth true leaf stage or later but before the crop canopy closes the
row. DO NOT USE ADJUVANTS. Occasional temporary corn leaf burn may occur and is similar to that observed
from liquid fertilizers. Recovery is generally rapid with no lasting effect. To reduce potential for crop damage,
application should be made to dry corn foliage when weather conditions are not extreme.

SENCOR® DF Lb/Acre
1/3 to 1/2
Apply specified dosage in a single preemergence application using 10 to 40 gallons of water per acre with ground spray equipment.
Apply before or after planting but before crop emergence. Thorough incorporation, either by rainfall or by mechanical means, is
essential for weed suppression. Under dry conditions, incorporate Sencor® into the top 1 to 2 inches of soil with spike harrows, or
similar shallow incorporation equipment, then cross harrow to insure uniform soil incorporation. Where soil surface is moist at the
time of application and rain follows before weed emergence, a broadcast application should provide adequate weed suppression.
Use on coarse-textured soils, sandy soils or any soil with less than 1 .5% organic matter will likely cause crop injury.
Use the higher rate on fine textured soils (high in clay or organic matter) and in fields with a history of high weed populations.
SPECIAL PRECAUTIONS:
• Crop injury may result if crop is under stress conditions caused by cold weather, poor soil fertility, disease or insect damage.
• Crop injury may result if application is followed by heavy rain. Avoid application of more than 1/2 inch of irrigation within one month
after application of Sencor® DF, or crop injury may occur.
• Do not use on clay knobs or poorly covered subsoils.
• Do not apply preemergence on shallow seedings less than 2 inches deep.
• Do not graze or feed treated vines to livestock within 40 days after application.
Maintain continuous spray tank agitation to keep material in suspension. Avoid overlapping of spray swaths and shut off spray booms
while turning, slowing or stopping, or crop injury will occur.
NOTE: This treatment may cause some chlorosis or minor necrosis. Because garbanzo bean varieties may vary in their susceptibility
to Sencor® DF, determine crop tolerance prior to adoption as a field scale practice to prevent possible injury.

in 10 or more gallons of water per acre with ground spray equipment or 5 or more gallons of water per acre with aerial spray equipment.
Apply Sencor® DF before or after planting. Thorough incorporation, either by rainfall or by mechanical means, is essential for weed
suppression. Under dry conditions, incorporate Sencor® DF into the top 1 to 2 inches of soil with spike harrows, or similar shallow
incorporation equipment, then cross harrow to insure uniform soil incorporation. Where soil surface is moist at the time of application
and rain follows before weed emergence, a broadcast application should provide adequate weed suppression.
Use the higher rate on fine-textured soils (high in clay or organic matter) and in fields with a history of high weed populations.
Sencor® DF may be applied pre- or post plant incorporated as a tank mix combination with FARGO® 4EC. Follow the Directions for
Use statements on both product labels.
52
POSTEMERGENCE APPLICATION: One postemergence application may be made per season. Use 1/6 to 1/3 Ib of Sencor® DF per
acre on lentils and spring peas. On winter peas, use 1/4 to 1/3 Ib of Sencor® DF per acre. For suppression of dog fennel, use 1/3 Ib
Sencor® DF per acre. Apply specified dosage in 20 or more gallons of water per acre with ground spray equipment or 5 or more
gallons of water per acre with aerial spray equipment. Do not exceed 40 psi with ground spray equipment. Apply as a broadcast spray
when weeds are small (less than 2 inches in height or diameter) and before crop is 6 inches tall.
Temporary chlorosis of the crop may occur. There is an added risk of crop injury if a postemergence application is made following a
previous preemergence or post plant incorporated Sencor® DF application.
Do not apply over very moist soils or wet crop foliage. Do not apply postemergence applications within 3 days after periods of cool,
wet, or cloudy weather or crop injury may occur.
Do not apply within 24 hours of treatment with other pesticides.
SPECIAL PRECAUTIONS (All applications):
• Do not apply more than 2/3 Ib Sencor® DF per acre per year. Crop injury niay result if crop is under stress conditions caused by
cold weather, low fertility, disease or insect damage.
• Crop injury may also result if application is followed by heavy rain.
• Do not use on coarse-textured soils, sandy soils or soils with less than 1.5% organic matter.
• Do not apply to "Estin" lentils.
• Do not use on clay knobs or poorly covered subsoils.
• Do not apply on shallow seedings less than 2 inches deep (preemergence only).
• Do not apply within 50 days of harvest of peas, or within 75 days of harvest of lentils. Do not graze or feed treated vines to
livestock within 40 days after application.
Maintain continuous spray tank agitation to keep material in suspension. Avoid overlapping and shut off spray booms while turning,
slowing or stopping, or crop injury will occur.
NOTE: This treatment may cause some chlorosis or minor necrosis. Because lentil and pea varieties may vary in their susceptibility to
Sencor® DF, determining crop tolerance prior to adoption as a field scale practice is suggested to prevent possible injury.
For additional precautions, restrictions, limitations, and sprayer clean-up information refer to the appropriate sections of this label.

Sencor® DF, a selective herbicide, is effective as a preemergence and an early postemergence broadcast application for control of
certain grass and broadleaf weeds. When applied as a spot treatment, it also provides excellent control of perennial grasses and
broadleaves.
Ground Application: Sencor® DF should be mixed by filling the spray tank half full of clean water. Then add the recommended
amouht of Sencor® DF to suit the total tank capacity and the rate of application per acre (preferably 25 to 35 gallons per acre).
Complete filling the tank and maintain sufficient agitation during mixing and spraying to ensure a uniform spray mixture.
Aerial Application: Sencor® DF is recommended for use in aerial spray equipment as a preemergence or postemergence application
to irrigated sugarcane. Aerial spray equipment should be calibrated to apply the proper amount of Sencor® DF in 5 to 10 gallons of
spray mixture per acre.
Sencor® DF applied preemergence or postemergence to the sugarcane as a broadcast spray or spot treatment will effectively control
the following when weeds are less than 3 inches in height.

• Do not apply more than a total of 1 1/3 Ib Sencor® DF per crop season.
• Do not apply the total amount of 1 1/3 Ib Sencor® DF within a time span of less than 35 days, except in the case of directed
sprays.
• Allow at least 14 days between applications, regardless of dosage or method of application or severe crop injury may occur.
• Do not apply within 7 days of harvest.
• Do not apply within 3 days after periods of cool, wet or cloudy weather, or crop injury will occur.
• Do not use hot caps on tomatoes within 7 days before or at any time after application of Sencor® DF. Do not treat seeded
tomatoes until plants have reached the 5 to 6 leaf stage or severe crop injury may occur.
57
• Crop injury or delayed maturity may result from broadcast or directed spray applications if tomatoes are growing under stress
conditions such as periods of drought or cool, wet and cloudy weather preceding application.
• For newly introduced tomato varieties with unknown tolerance to Sencor® DF, treat only a small area to determine if Sencor® DF
can be used without injury to the crop.
• Aerial application isxprohibited.
DO NOT USE SENCOR® DF ON TOMATOES IN KERN COUNTY, CALIFORNIA.
CEREALS
(Spring and Winter Barley and Winter Wheat)
Sencor® DF herbicide is recommended for control or suppression of certain grasses and broadleaf weeds when applied
postemergence to spring and winter barley or winter wheat. Sencor® DF alone and several tank mixture treatments are recommended
for use in the following states: AR, GA, ID, IL, IN, KS, KY, LA, MS, MO, MT, NV, OH, OK, OR, TN, TX, UT, WA.
Mixing: See the "General Information" section of this label for specific mixing procedures. When tank mixing, carefully follow the
instructions on this label. Refer to the other product labels registered for use in barley and winter wheat for additional use directions,
rates, weeds controlled and restrictions.
Application: Sencor® DF may be applied by aerial or ground application equipment. Use a minimum spray volume of 2 gpa by air and
10 gpa by ground. Uniform spray coverage is necessary to obtain optimum weed control and to minimize potential for crop injury. Do
not exceed rates specified on this label. Do not apply Sencor® DF through any type of irrigation equipment. Apply Sencor® DF when
the crop is healthy and actively growing. Sencor® DF may be applied more than once per crop season. Allow a minimum of 21 days
between applications if wheat is actively growing or allow 45 days between applications if wheat is growing in adverse conditions, has
entered dormancy or is stressed due to frost damage, disease, drought or excessive moisture. Do not use on soils containing less than
0.75% organic matter. Do not apply more than a total of 10,66 ounces Sencor® DF (8 ounces active ingredient) per acre per year. On
irrigated cereals, do not apply more than 0.5 inch of water for the first irrigation, the maximum amount for each additional irrigation
should not exceed 1 inch. Allow a minimum of 14 days between the first irrigation and subsequent irrigations.
Performance Factors: Weed control may not be observed for 2 to 4 weeks under normal growth conditions and for 4 to 6 weeks under
very dry conditions. Moisture (at least 1/2 inch) is required within 2 to 3 weeks after application to move Sencor® DF into the weed root
zone. Lack of adequate moisture after application may result in poor or erratic weed control. Control or suppression of listed weeds is
dependent on weed size at time of application. Control or suppression may be reduced if broadleaf weeds are taller than 1 inch or
grasses have more than 2 leaves.
Tank mixtures: Sencor® DF may be tank mixed with Ally®, Amber®, Finesse®, Glean® FC, Harmony® Extra, 2,4-D®, MCPA®,
Igran®, Banvel®/Banvel® SGF, Bronate or Buctril® herbicides. A nonionic surfactant containing at least 80% active ingredient may be
used in Sencor® DF tank mixes with sulfonylurea herbicides (Ally®, Amber®, Finesse®, Glean® FC and Harmony® Extra). Do not use
a crop oil concentrate or any adjuvant containing vegetable or petroleum oils with any Sencor® DF mix as crop injury may result.
Additional pesticides may also be tank mixed with Sencor® DF unless specifically prohibited on the mix products' label. In some
instances, combinations with organophosphate insecticides may cause temporary leaf yellowing and/or crop injury, especially when
widely fluctuating day/night temperatures occur near application. Always refer to the other product labels registered for use on cereals
for additional directions, rates and weed species controlled. Observe all precautions and limitations on labeling of all products used in
mixtures.
Feeding Restrictions: Do not graze wheat within 14 days of Sencor® DF application or harvest grain within 21 days after last
application. Do not graze or harvest barley before crop maturity. For tank mix combinations, follow the most restrictive label.
SPECIAL PRECAUTIONS: Cereal Injury - Crop injury may occur if Sencor® DF is applied:
• When the crop is under stress such as winter kill, frost damage, disease, drought or excessive moisture, severe grazing, or when
these conditions follow the application.
• In combination with fluid fertilizer especially with the addition of surfactant.
• Prior to the growth stage specified on this label.
• To soils high in lime or sodium, a pH greater than 7.7, calcareous, gravelly, thinly covered or exposed subsoil areas.
• To fields where cereal seeds have been planted less than 1 inch deep.
• To a non-winter hardy wheat or barley variety.
• To a sensitive wheat or barley variety as listed below.
• To frozen soil or crop still in winter dormancy.
Cereal Rotations Following Potatoes Treated with Sencor® DF: If planting a sensitive cereal variety (listed under the wheat and barley
variety tolerance portion of this label), following potatoes treated with Sencor® DF or metribuzin containing products, refer to the potato
section of the Sencor® DF label for special cultural practices to follow.
APPLICATION RECOMMENDATIONS
Sencor® DF alone or in a tank mix with labeled broadleaf herbicides may be applied by aerial or ground spray equipment as a
broadcast postemergence spray.

FOR WEED CONTROL IN A WHEAT/FALLOW/WHEAT ROTATION
(Idaho, Oregon, Utah and Washington Only)
Sencor® DF may be applied to provide weed control during the fallow period after wheat harvest or in the Spring before winter wheat is
planted. Winter wheat can be seeded 4 months (120 days) after Spring application. Mechanical tillage or the application of a contact
herbicide may be required to control weeds germinating prior to seeding of winter wheat. Best results will be obtained where straw and
chaff are evenly distributed across the field.
For specific application information see the "General Information" section in the front of this label.
Where weed growth is present at application time, Sencor® DF should be applied with Gramoxone® or other contact herbicide. Refer
to the other product label registered for additional directions, rates, and weed species controlled.
