GENERAL PRECAUTIONS AND RESTRICTIONS
• Do not use on other crops grown for food or forage. Apply this product only as specified on this label. Do not rotate any crop not
listed on this label for 18 months following application of Sencor® 4.
• Do not allow sprays to drift on to adjacent desirable plants.
• Observe all cautions and limitations on labeling of all products used in mixtures.
• For all uses: Low pressure and high volume hand wand equipment is prohibited.
CHEMIGATION :
Sencor® 4 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 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® 4. 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 pivot 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® 4 at the specified rate (See
BROADCAST APPLICATION INSTRUCTIONS) 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 (120012 = 600); to treat 135 acres at 1 pint/acre, 135 pints (16 gallons and 7 pints) of
Sencor® 4 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. c c''c c c
Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) effectively deigned and
constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock. ,.' c tc cu c i;
Do not apply when wind speed favors drift beyond the area intended for treatment. c c L t ^ c
Maintain continuous agitation in the injection nurse tanks during the herbicide application, sufficient to keepL herbicide in suspension.•. c
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 cor'itinjjb'ufi injection-iii '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-ratrvoving the<chem;cal from
the zone of effectiveness. Where sprinkler distribution patterns do not overlap sufficiently unacceptable wesd-eo.n'trol may result.
Where sprinkler distribution patterns overlap excessively crop injury may result. Allow sufficient time for pesticide to be fbshed through
all lines and all nozzles before turning off irrigation water. To insure that lines are flushed and free of remaining pesticide, 'a'n'ir'idicator
dye may be injected into the lines to mark the end of the application period. , 11

r rUse 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 chajacterized 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'tkat 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. fL L!;'',. c
SENSITIVE AREAS: Sencor® 4 should only be applied when the potential for drift to adjacent sensitive areas c(e.g residential] areas,
bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal (e.g. whe;Vwind is blowing''away
from the sensitive areas). l' I' .. '' c

r
APPLICATION OF SENCOR® 4 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® 4 in a minimum of 1.0 to 40 gallons of spray mixture per acre broadcast.
Banded Application: Use proportionally less Sencor® 4 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® 4. (2) To treat a 14-inch
band on rows 42 inches apart, use one-third of the broadcast rate of Sencor® 4. :
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® 4 is tank mixed with Lasso®.
For All Applications of Sencor® 4: Sprayer must be accurately .calibrated before applying Sencor® 4. 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® 4 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® 4 IN FLUID FERTILIZERS
Sencor® 4 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® 4 and tank mix combinations which include Sencor® 4 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® 4 with 8 teaspoonfuls of water (1:4 ratio) in a quart jar by adding the water first and followed
with Sencor® 4. 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® 4 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® 4
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® 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® 4 ON DRY BULK FERTILIZER 9<.<,*\f
Dry bulk fertilizer may be impregnated or coated with Sencor® 4 for application to established alfalfa and to soybeans. Ali'lr^ructions,
cautions, and special precautions on this label must be followed along with state regulations relating to dry bulk fertilizer blending,
impregnating and labeling. [•c l• j-L £ *
Impregnation: To impregnate, use a system consisting of a belt, conveyor, or closed drum which is used for dry tsulk fertilizer "blending.
Any commonly used fertilizer can be impregnated with Sencor® 4 except ammonium nitrate, or fertilizers conltaihilng ammonium nitrate,
potassium nitrate, or sodium nitrate. Do not use on powder limestone. '' ; ' t L t
Apply using a minimum of 200 Ibs dry bulk fertilizer per acre and up to a maximum of 450 Ibs per acre. Tojiripregnate or coat clry bulk
fertilizer, mix Sencor® 4 with sufficient water to form a sprayable slurry. The delivery nozzles must be directed'(b deliver a fine spray
toward the fertilizer for thorough coverage while avoiding spray contact with mixing equipment. Uniform impregnation of S^ncQr® 4 to
dry bulk fertilizer will vary and if the absorptivity is not adequate, an absorbent 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'ia^used
with Sencor® 4, 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 specified rate of Sencor® 4 per acre from the appropriate, section of this label and refer to the formula below to
determine the amount of Sencor® 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.
Pt Sencor® 4 X 2000 Ib Fertilizer = Pt Sencor® 4
Per 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 specified 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 of 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® 4 is to be used in combination with another herbicide, follow directions on this
label for combinations, rates, crops, incorporation, and special precautions.

Sencor® herbicide tank mix combinations are recommended for preplan! incorporated applications, preemergence surface applications,
split-shot application and extended split-shot application. Sencor® 4 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® 4 can
be applied as a post emergence directed spray to soybeans in certain states.
SPECIAL PRECAUTIONS (Soybeans): Injury to soybeans may occur when Sencor® 4 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, do not use Sencor® 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 or your seed supplier for
information on the tolerance of newly released soybean varieties, prior to use of Sencor®.
• 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®. 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® is applied
alone or with Treflan®, Prowl® or Lasso®.
Do not use treated vines for feed or forage when Sencor® is applied with Sonalan®, linuron plus Lasso.
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® 4 as directed on this label, the field may be replanted-*.e soybeans.
When replanting a minimum of tillage is recommended. Do not apply a second treatment as injury to soybeans may occur., t

(calcareous) soils in Nebraska, Minnesota, South. Dakota and North Dakota only, apply Sencor® 4 at rates of 1/2 pt/acre on medium
soils and 1/2 to 3/4 pt/acre on fine soils regardless of soil organic matter percentage (use 3/4 pt only where soil pH is less than 7.5
and weed pressure is heavy). The 1/2 pt/acre rate of Sencor® 4 alone can be applied regardless of soil pH. For control of other
weeds listed on this label use Sencor® 4 at full rates specified 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® 4 on soybeans in coarse soils with 0.5% or more organic matter in
certain states.
USES OF SENCOR® HERBICIDE IN COMBINATION WITH OTHER HERBICIDES
SEQUENTIAL APPLICATION OF SCEPTER FOLLOWING SENCOR® 4
If needed, application of Sencor® 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 pints 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 COG 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® 4 tank mixed with either Treflan, Lasso, Prowl or Sonalan and followed by a
preemergence surface application of Sencor® 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, 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®. Carefully observe the Special Precautions section concerning the use of Sencor® in tank mix combinations on soybeans.
When a Split-Shot application of Sencor® 4 with Prowl, Treflan, or Sonalan is used, the preplant incorporated tank mix may 63 applied
up to 21 days prior to planting soybeans; with Lasso, the preplant incorporated tank mix may be applied up to 14 days pribctatpllnting.
On medium and fine textured soils with greater than 2% organic matter, a rate range is specified for the Sencor® 4 preerri6rt)6itice
overlay application. The higher rate should be used (a) in fields with a history of severe broadleaf weed pressure, (b) whei!: trie time
between preplant incorporated tank mix and preemergence overlay applications approaches the maximumtst&tQd-above, andfor (c)
when the organic matter content of the soil is at the upper end of the indicated range. c '' ' (<. cc

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® 4 in the preplant incorporated 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® 4 by 1/4 pt/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® tank mixed with Lasso, followed by a preemergence
surface application of Sencor® tank mixed with 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® 4 with 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 specified, 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-UpGfoVGramoxone.C C C C

additional weeds not specified on this label.
Sencor® plus Treflan Tank Mix Application: A single application of a tank mix combination of Sencor® 4 and Treflan EC will control more
broadleaf and grass weeds in soybeans than when either herbicide is used alone.
Prepare the soil surface by deep plowing, offset disking or tandem disking prior to the application of the herbicide combination. The soil
surface should be well prepared and free of clods and trash.
This Sencor® plus Treflan tank mix combination may be applied and incorporated into the soil up to 10 days before planting.
Mixing: Refer to the General Information section in the front of this label.
Application: For specific application information refer to the General Information section in the front of this label.
Apply Sencor® 4 plus Treflan to the soil surface and incorporate in the same operation, if possible. Variable weed control may result
from delayed incorporation if Sencor® plus Treflan are applied to a wet, warm soil surface or if the wind velocity is 10 miles per hour or
higher. Use machinery that mixes Sencor® plus Treflan thoroughly with the soil. Incorporation may be delayed up to 24 hours after
application. Shallow incorporation with implements set to cut less than 2 inches deep may result in erratic weed control. Do not use
spike or spring-tooth harrows alone for incorporation.

1 Refer to "Soil Texture" paragraph on this label for specific soil classification. On coarse textured soils with a calcareous surface
area or a pH of 7.5 or higher, do not use on loamy sand or sandy loam soils with less than 1 % organic matter.
2The higher rate of Sencor® is recommended for preemergence tank mix application and for the control of sicklepod and hemp
sesbania. Use the lower rate of Sencor® in the preplan! incorporated 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 Higher rate is recommended under moderate to heavy weed infestations.

r rSOUTHERN AND SOUTHEASTERN STATES ONLY POSTEMERGENCE DIRECTED SPRAY APPLICATIONS
Sencor® 4 can be applied in postemergence directed sprays to soybeans for control of certain weeds which escape preplant or
preemergence herbicide applications and for control of additional flushes of weeds that may occur after soybeans have emerged.
Postemergence directed sprays of Sencor® 4 can be applied to soybeans in addition to a preemergence or preplant application of
Sencor® herbicide according to label directions.
Weeds Controlled: Sencor® 4, applied postemergence to soybeans as a directed spray according to directions on this label, will control
the following at rates shown (broadcast basis) when grasses and common ragweed are less than 1-inch tall and other broadleaves are
less than 3-inches tall:
1/2 Pt/Acre
1/2 to 1 Pt/Acre
1 Pt/Acre
Florida beggarweed (Desmodium tortuosum)
Pigweeds (Amaranthus spp.)
Carpetweed (Mollugo verticillata)
Cocklebur (Xanthium pensylvanicum)
Dayflower (Commelina spp.)
Sesbania (Sesbania spp.)
Ragweed, common (Ambrosia artemisiifolia)
Mexicanweed (Caperonia castaniifolia)
Purslane (Portulaca oleracea)
Sicklepod (Cassia obtusifolia)
Velvetleaf (Abutilon theophrasti)
Crabgrass (Digitaria spp.)
Prickly sida/Teaweed (Sida spinosa)
At the rate of 1/2 pt/acre morningglory species, (Ipomoea spp.) horsenettle, (Solanum spp.) Florida pusley, (Richardia scabra) spotted
spurge (Euphorbia maculata) and wild poinsettia (Euphorbia heterophylla) are suppressed when Sencor® 4 is applied before these
weeds are 3 inches tall. The 1 pt/acre rate will suppress broadleaf signalgrass (Brachiaria platyphylla) up to 1 inch tall.

APPLICATION INSTRUCTIONS
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® 4 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® 4 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® 4 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® 4. 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. (*•'•c': c
Ground Application: Sencor® 4 is recommended for use with ground spray equipment applied as a preemergence and/or'

FIELD CORN
For newly introduced varieties of carrots with unknown tolerance to Sencor®, treat only a small area to determine if Sencor® can
be used without injury to the crop.
POSTEMERGENCE APPLICATION
Sencor® 4 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® 4 include:
2,4-D
Atrazine
Banvel
Basagran
Buctril/Buctril Gel
Laddok S-12
Marksman
Buctril + atrazine (Premix)
Clarity
Pursuit*
Resource
Scorpion III
Tough
* Use only on Pursuit resistant/tolerant corn hybrids (IMI- Corn).
APPLICATION: Sencor® 4 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.
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® 4 plus atrazine, Basagran, Laddok S-12, Buctril, Buctril + atrazine, Pursuit, Resource, Tough or 2,4-D amine
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® 4 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, 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 tank mix partner's label for further precautions and instructions.
POST DIRECTED APPLICATION
Sencor® 4 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 instructions, refer to the appropriate tank mix partner's label.
ADJUVANTS c c c c
The adjuvant types listed below may be utilized with certain Sencor® 4 tank mix combinations. Consult the tank mix instructions

RAINFASTNESS
Sencor® 4 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® 4 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 (8 fl oz Sencor® 4) 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® 4 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*
For corn greater than 8-inches tall, apply as a directed spray with drop nozzles before
tassel emergence. 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.
For corn 8 to 36 inches tall, apply as a directed spray with drop nozzles. Application may
be made up to 15 days prior to corn tasseling. 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 at 0.5 pt/acre,
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 directed spray with drop nozzles before tassel emergence. 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

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

c cSPECIAL 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®, 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®, determine crop tolerance prior to adoption as a field scale practice to prevent possible injury.

POSTEMERGENCE APPLICATION: One postemergence application may be made per season. Use 1/4 to 1/2 pint of Sencor® 4 per acre
on lentils and spring peas. On winter peas, use 3/8 to 1/2 pint of Sencor® 4 per acre. For suppression of dog fennel, use 1/2 pint
Sencor® 4 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® application.
Do not apply over very moist soils or wet crop foliage. Do not apply postemergence 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 1 pint of Sencor® 4 per acre per year. Crop injury may 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. L c ' < ' < (. C C C

Sencor®, 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® 4 should be mixed by filling the spray tank half full of clean water. Then add the specified amount of
Sencor® 4 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 insure a uniform spray mixture.
Aerial Application: Sencor® 4 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® 4 in 7 to 10 gallons of spray
mixture per acre.
Sencor® 4 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.

REMARKS
PREPLAN! INCORPORATED-TRANSPLANT TOMATOES ONLY: Apply specified dosage in 10 or
more gallons of water per acre as a broadcast spray to the soil surface immediately before transplanting.
Incorporate to a depth of 2 to 4 inches with equipment capable of uniformly mixing the chemical into the
soil. This application may be made alone or in a tank mix combination with Trifluralin E.G. When
transplanting tomatoes, place the root system of the plants below the herbicide incorporation zone or
injury may occur. Refer to the Trifluralin label for specific rate of application and for additional precautions
and restrictions for tomatoes.
POSTEMERGENCE BROADCAST SPRAY-ESTABLISHED TOMATOES:
Apply specified dosage in 20 or more gallons of water per acre as a broadcast spray, or apply in 1/4 to
3/4 inch of water (use 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 apply in the last 15 to 30 minutes of set in permanent solid set sprinkler
systems. One or more applications may be applied per use season. Allow at least 14 days between
applications or severe crop injury may occur. For transplanted tomatoes, do not apply until transplants
have recovered from transplant shock and new growth is evident. Do not apply to tomatoes within 24
hours of application of other pesticides. Do not tank mix with other pesticides. (See "Special
Precautions" below.)
POSTEMERGENCE DIRECTED SPRAY-ESTABLISHED TOMATOES:
Apply specified dosage in 20 or more gallons of water per acre as a directed spray. One or more
applications may be applied per use season. Allow at least 14 days between applications or severe crop
injury may occur. Avoid contacting tomato foliage with spray. This method of treatment is recommended
for use in fields with a history of severe weed pressure or in fields infested with hard-to-control weeds.
For transplanted tomatoes, do not apply until transplants have recovered from transplant shock and new
growth is evident. Do not apply to tomatoes within 24 hours of application of other pesticides. (See
"Special Precautions" below.) When banding see the appropriate section in the front of this label.
* Use the higher rate in fields with a history of severe weed pressure and for maximum residual weed control.
SPECIAL PRECAUTIONS (Tomatoes): Do not apply more than a total of 2 pts. Sencor® 4 per crop season.
Do not apply the total amount of 2 pt Sencor® 4 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® 4. Do not treat seeded tomatoes until
plants have reached the 5 to 6 leaf stage or severe crop injury may occur.
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®, treat only a small area to determine if Sencor® 4 can be
used without injury to the crop.
Aerial application is prohibited.

rates, weeds controlled and restrictions. c <. c c <. c c.
Application: Sencor® 4 may be applied by aerial or ground application equipment. Use a minimum spray volume of 2 gpa by air gnci 10
gpa by ground. Uniform spray coverage is necessary to obtain optimum weed control and to minimize potential for crop injury^ PA not
exceed rates specified on this label. Do not apply Sencor® 4 through any type of irrigation equipment. Apply Sencor® 4 when the crop
is healthy and actively growing. Sencor® 4 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 16 fluid ounces Sencor® 4 (8 ounces active ingredient) per acre per year. On

c Sb
irrigated wheat and barley, 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® 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® 4 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® 4 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® 4 mix as crop injury may result. Additional pesticides may also be
tank mixed with Sencor® 4 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 wheat and barley 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® 4 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: Wheat and Barley Injury - Crop injury may occur if Sencor® 4 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 wheat and barley 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.
Wheat and Barley Rotations Following Potatoes Treated with Sencor® 4: If planting a sensitive wheat and barley variety (listed under the wheat

Weeds Suppressed
Sencor® 4 control of the following weeds varies from poor to excellent depending on time of application, stage of growth at application,
temperatures and soil moisture conditions following treatment. For maximum effect on these weeds, apply the highest specified rate at
the earliest growth stage timing for each particular soil type and organic matter. Suppression is a reduction in weed size and growth as
compared to a non-treated area in the same field.

FOR WEED CONTROL IN A WHEAT/FALLOW/WHEAT ROTATION "c"
(Idaho, Oregon, Utah and Washington Only) c c c I °' <- CO C
Sencor® 4 may be applied to provide weed control during the fallow period after wheat harvest or in the Spring before wintercwheat is
planted. Winter wheat can be seeded 4 months (120 days) after Spring application. Mechanical tillage or^he'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. c c c c i. c
C c '" C L
For specific application information see the "General Information" section in the front of this label. ^ 10 c L
Where weed growth is present at application time, Sencor® 4 should be applied with Gramoxone or other coriiaet/herbicide. Refer to
the other product label registered for additional directions, rates, and weed species controlled. c

* Note: Since control of these weeds may be variable depending on moisture following application, the higher labelled rate is recommended.
After Harvest Application (Fall Fallow): Sencor® 4 may be applied to wheat stubble after harvest in the Fall. Apply 1 to 1-1/4 pt per acre
broadcast before weeds emerge. Use higher rate for longer weed control or for weeds designated as requiring the higher rate for
control. Rainfall (1/2 inch or more) is necessary for herbicide activation .
Do not plant crops in treated areas for at least 10 months following Fall applications. Do not rotate any crop not listed on this label for
18 months following application of Sencor® 4.
Sencor® 4 may be applied at 1 to 1-1/4 pt per acre as directed above for a Fall application. If other vegetation is present at the time of
application use a contact herbicide.
Spring Application (Summer Fallow): Sencor® 4 may be applied to wheat stubble in the Spring. Apply 3/4 to 1 pt per acre broadcast
before weeds emerge in the Spring. Use higher rate for longer weed control or weeds designated as requiring higher rate for control.
Rainfall (1/2 inch or more) is necessary for herbicide activation.
Precautions and Restrictions: Do not graze treated fields. Do not plant Spring seeded barley following Fall fallow applications of Sencor®.
Where Sencor® was applied in the Fall, do not apply Sencor® in the Spring.
FOR WEED CONTROL IN A FALLOW ROTATION WITH BARLEY AND WHEAT
(Colorado, Kansas, Montana, Nebraska, and Wyoming Only)
Sencor® 4 may be applied to provide weed control during the fallow period after wheat or barley harvest or in the Spring before planting
of Winter wheat or barley. Mechanical tillage or the application of a contact herbicide may be required to control weeds germinating
prior to seeding of Winter wheat or barley.
For specific application information see the "General Information" section in the front of this label.
Where weed growth is present at application time, Sencor® 4 should be applied with Gramoxone, Roundup, or other contact herbicide.
Refer to the other product label registered for additional directions, rates, and weed species controlled. Do not plant crops in treated
areas earlier than 10 months following Fall applications. Do not rotate any crop not listed on this label for 18 months following
application of Sencor® 4.
