User Safety Recommendations
Users should
• Wash hands before eating drinking chewing gum using tobacco or using the toilet
Environmental Hazards
Do not apply directly to water to areas where surface water is present or to mtertidal
areas below the mean high water mark Do not contaminate water when disposing of
equipment wash water or nnsate
Ground Water Advisory
S metolachlor has the potential to leach through soil into ground water under certain
conditions as a result of agricultural use Use of this chemical in areas whe/e soils are
permeable particularly where the water table is shallow may result in ground water
contamination
Metnbuzm is a chemical which can travel (seep or leach) through soil and can
contaminate ground water which may be used as drinking water Metnbuzm has been
found in ground water as a result of agricultural use Users are advised not to apply
metribuzm where the water table (ground water) is close to the surface and where the
soils are very permeable i e well drained soils such as loamy sands Your local
agricultural agencies can provide further information on the type of soil in your area and
the location of ground water
Surface Water Advisory
S metolachlor has the potential to contaminate surface water through ground spray drift
Under some conditions S metolachlor may also have a high potential for runoff into
surface water (primarily via dissolution in runoff water) for several months post
application These include poorly draining or wet soils with readily visible slopes toward
adjacent surface waters frequently flooded areas areas overlaying extremely shallow
ground water areas with in field canals or ditches that dram to surface water areas not
separated from adjacent surface waters with vegetated filter strips and areas overlaying
tile drainage systems that dram to surface water

GENERAL INFORMATION
Observe all precautions and limitations on the labels of each product used in tank
mixtures Tank mixture partners must be registered in states where they are used
Refer to and follow the label for each tank mix product used
Do not apply under conditions which favor runoff or wind erosion of soil containing this
product to nontarget areas
To prevent off site movement due to runoff or wind erosion
1 Avoid treating powdery dry or light sand soils when conditions are favorable for
wind erosion Under these conditions the soil surface should first be settled by
rainfall or irrigation
2 Do not apply to impervious substrates such as paved or highly compacted
surfaces
3 Do not use tailwater from the first flood or furrow irrigation of treated fields to treat
nontarget crops unless at least 1/2 inch of rainfall has occurred between
application and the first irrigation
Mixing Instructions
Prepare no more spray mixture than is needed for the immediate operation Thoroughly
clean the spray equipment before using Boundary Vigorous agitation is necessary to
maintain uniformity of the spray mixture Maintain maximum agitation throughout the
spraying operation Do not allow spray mixture to stand overnight in the spray tank
Flush the spray equipment thoroughly following each use and apply the rmsate to a
previously treated area
»
Application in Water or Fluid Fertilizers >
Boundary Alone Add 1/3 of the required amount of water or fluid fertilizer to the spray
or mixing tank With the agitator running add Boundary into the spray tafk Continue
agitation while adding the remainder of the water or fluid fertilizer Begin application of
the spray solution after the Boundary has completely dispersed in the water or fluid
fertilizer Maintain agitation until all of the mixture has been applied 3
Boundary + Tank Mixtures Add 1/3 of the required amount of water or fluid fertilizer to
the mix tank Start the agitator running before adding any tank mix partners In
general tank mix partners should be added in this order products packaged in water
soluble packaging wettable powders wettable granules (dry flowables) liquid
flowables liquids such as Boundary and emulsifiable concentrates Always allow each
tank mix partner to become fully dispersed before adding the next product Provide
sufficient agitation while adding the remainder of the water Maintain agitation until all of
the mixture has been applied
Notes (1) When using Boundary in tank mixtures all products in water soluble
packaging should be added to the tank and mixed with plain water before any other tank
mix partner including Boundary Allow the water soluble packaging to completely
dissolve and the product(s) to completely disperse before adding any other tank mix
partner to the tank (2) Water soluble packets will not properly dissolve in most spray
solutions that contain fluid fertilizers
If using Boundary in a tank mixture observe all directions for use crop/sites use rates
dilution ratios precautions and limitations that appear on the tank mix product label
No label dosage rate should be exceeded and the most restrictive label precautions
and limitations should be followed
Boundary is compatible with most common tank mix partners However the physical
compatibility of Boundary with tank mix partners should be tested before use To
determine the physical compatibility of Boundary with other products use a jar test as
described below
Compatibility Test
Ajar test is recommended before tank mixing to ensure compatibility of Boundary with
other pesticides The following test assumes a spray volume of 25 gals /A For other
spray volumes make appropriate changes in the ingredients
Note Nitrogen solutions or complete fluid fertilizers may replace all or part of the water
in the spray Because liquid fertilizers vary even within the same analysis always
check compatibility with pesticide(s) before use Incompatibility of tank mixtures is
more common with suspensions of fertilizer and pesticides
^ ^
Test Procedure
j
1 Add 1 0 pt of carrier (fertilizer or water) to each of 2 one qt jars witr? tight lid>
Note Use the same source of water that will be used for the tanK mix and '
conduct the test at the temperature the tank mix will be applied ) 1
2 To one of the jars add % tsp or 1 2 milliliters of a compatibility agent appro yejd .,
for this use such as Compex® or Unite® (% tsp is equivalent to 2 0 pts /1GO
gals spray) Shake or stir gently to mix
3 To both jars add the appropriate amount of pesticide(s) in their relative
proportions based on recommended label rates If more than one pesticide is
used add them separately with dry pesticides first flowables next and
emulsifiable concentrates last After each addition shake or stir gently to
thoroughly mix
4 After adding all ingredients put lids on and tighten and invert each jar ten times
to mix Let the mixtures stand 15 30 minutes and then look for separation large
flakes precipitates gels heavy oily film on the jar or other signs of
incompatibility Determine if the compatibility agent is needed in the spray
mixture by comparing the two jars If either mixture separates but can be
remixed readily the mixture can be sprayed as long as good agitation is used If
the mixtures are incompatible test the following methods of improving
compatibility (a) Slurry the dry pesticide(s) in water before addition or (b) add %
the compatibility agent to the fertilizer or water and the other 1/2 to the
emulsifiable concentrate or flowable pesticide before addition to the mixture If
incompatibility is still observed do not use the mixture
5 After compatibility testing is complete dispose of any pesticide wastes in
accordance with the Storage and Disposal section in this label
Ground Spray Equipment Apply Boundary alone or in tank mixtures by ground
equipment in a minimum of 10 gals of spray mixture per acre unless otherwise
specified
Use sprayers that provide accurate and uniform application Calibrate the sprayer
before use at the beginning of the season For Boundary tank mixtures with wettable
powder or dry flowable formulations screens and strainers should be no finer than
50 mesh
Calculate the amount of herbicide needed for band treatment by the formula
Band width in inches X broadcast rate = amount needed
Row width in inches per acre per acre of field
Chemigation Do not apply Boundary through any type of irrigation system
Aerial Application Apply Boundary in water using a minimum spray volume of
2 gals /A Avoid application under conditions where uniform coverage cannot be
obtained or where excessive spray drift may occur Make applications at a maximum
height of 10 ft above the soybeans with low drift nozzles at a maximum pressure of
40 psi
Avoid application to humans or animals Flagmen and loaders should avoid inhalation
of spray mist and prolonged contact with skin
Aerial Drift Management
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
10
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 outermost nozzles on the boom must not exceed % the
length of the wmgspan or rotor
2 Nozzles must always point backward parallel with the air stream and never be
pointed downward more than 45 degrees
Where states have more stringent regulations they should be observed
The applicator should be familiar with and take into account the information covered in
the Aerial Drift Reduction Advisory Information section below
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 manufacturers 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
11
• 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 % of the
wmgspan or rotor length may further reduce drift without reducing swath width
Application Height
Applications should not be made at a height greater than 10 ft above the top of the
largest plants unless a greater height is required for aircraft safety Making applications
at the lowest height that is safe reduces exposure of droplets to evaporation and wind
Swath Adjustment
When applications are made with a crosswind the swath will be displaced downward
Therefore on the up and downwind edges of the field the applicator must compensate
for this displacement by adjusting the path of the aircraft upwind Swath adjustment
distance should increase with increasing drift potential (higher wind smaller drops etc )
Wind
Drift potential is lowest between wind speeds of 2 10 mph However many factors
including droplet size 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
12
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
Boundary 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 nontarget crops) is minimal (e g when wind is blowing away from the sensitive
areas)
Avoid application to humans or animals Flagmen and loaders should avoid inhalation
of spray mist and prolonged contact with skin
Cleaning Equipment after Application
Because some crops other than soybeans are sensitive to low rates of Boundary
special attention must be given to cleaning equipment before spraying a crop other than
those registered for use and on this label Mix only as much spray solution as needed
Immediately after spraying clean equipment thoroughly using the following procedure
1 Flush tank hoses boom and nozzles with clean water
2 Prepare a cleaning solution of one gal of household ammonia per 50 gals of
water Many commercial spray tank cleaners may be used as well Consult your
Syngenta representative for a partial listing of approved tank cleaners and more
information about proper tank cleaning procedures Do not use chlorine based
cleaners such as Clorox®
3 When available use a pressure washer to clean the inside of the spray tank with
this solution Take care to wash all parts of the tank including the inside top
surface Completely fill the sprayer with the cleaning solution to ensure contact
of the cleaning solution with all internal surfaces of the tank and plumbing Start
agitation in the sprayer and thoroughly recirculate the cleaning solution for at
least 15 minutes All visible deposits must be removed from the spraying
system
4 Flush hoses spray lines and nozzles for at least one minute with the cleaning
solution
5 Dispose of rmsate from steps 1 3 as described under the Environmental
Hazards section of the Precautionary Statements
6 Repeat steps 2 5
13
7 Remove nozzles screens and strainers and clean separately in the ammonia
cleaning solution after completing the above procedures
8 Rinse the complete spraying system with clean water
Impregnation onto Dry Bulk Granular Fertilizers
Many dry bulk granular fertilizers may be impregnated or coated with Boundary and
used to control weeds in soybeans When applying Boundary with dry bulk fertilizers
follow all directions for use and precautions on the Boundary label regarding target
crops rates per acre soil texture application methods and rotational crops
Complying with all individual state regulations relating to dry bulk granular fertilizer
blending registration labeling and application is the responsibility of the individual
and/or company selling the herbicide/fertilizer mixture
Prepare the herbicide/fertilizer mixture by using any closed drum belt ribbon or other
commonly used dry bulk fertilizer blender Nozzles used to spray Boundary onto the
fertilizer must be spaced to provide uniform spray coverage Care should be taken to
aim the spray onto the fertilizer only avoiding the walls of the blender
If the herbicide/fertilizer mixture is too wet add a highly absorptive material such as
Agsorb® FG or Celatom MP 79® or similar granular clay or diatomaceous earth
materials to obtain a dry free flowing mixture Absorptive materials should be added
only after the herbicide has been thoroughly blended into the fertilizer mixture Best
application results will be obtained by using a granule of 6/30 particle size or of a size
similar to that of the fertilizer materials being used Generally less than 2% by weight
of absorptive material will be needed Avoid using more than 5% absorptive material by
weight
Calculate the amount of Boundary to be used by the following formula
2 000 X pts of Boundary per acre = pts of Boundary
Ibs of fertilizer per acre per ton of fertilizer
Pneumatic (Compressed Air) Application
High humidity high urea concentrations low fertilizer use rates and dusty fertilizer may
cause fertilizer mixtures to build up or plug the distributor head air tubes or nozzle
deflector plates To minimize buildup premix Boundary with Exxon Aromatic 200 at a
rate of 2 0 2 5 pts /gal of Boundary Aromatic 200 is a noncombustible/nonflammable
petroleum product Aromatic 200 may be used in either a fertilizer blender or through
direct injection systems Drying agents should not be used when using Aromatic 200
14
Notes (1) Mixtures of Boundary and Aromatic 200 must be used on dry fertilizer only
Poor results or crop injury may result if these mixtures are used in water or liquid
fertilizer solutions for spraying applications (2) When impregnating Boundary in a
blender before application a drier mixture can be obtained by substituting a drying
agent for Aromatic 200 The use of Agsorb FG or another drying agent of 6/30 particle
size is recommended (3) Drying agents are not recommended for use with On The Go
impregnation equipment
Precautions To avoid potential for explosion (1) Do not impregnate Boundary on
ammonium nitrate potassium nitrate or sodium nitrate either alone or in blends with
other fertilizers (2) Do not combine Boundary with a single superphosphate (1 20 0) or
treble superphosphate (0 46 0) (3) Do not use Boundary on straight limestone since
absorption will not be achieved Fertilizer blends containing limestone can be
impregnated
Application of Impregnated Dry Bulk Granular Fertilizer
Apply 200 700 Ibs of the herbicide/fertilizer mixture per acre For best results apply
the mixture uniformly to the soil with properly calibrated equipment immediately after
blending Uniform application of the herbicide/fertilizer mixture is essential in order to
prevent possible crop injury to subsequent rotational crops Nonuniform application
may also result in unsatisfactory weed control In areas where conventional tillage is
practiced a shallow incorporation of the mixture into the soil is recommended to obtain
satisfactory weed control On fine or medium textured soils in areas where soil
incorporation is not planned i e reduced tillage situations or in some conventional till
situations make applications approximately 30 days before planting to allow moisture to
move the herbicide/fertilizer mixture into the soil On coarse textured soils make
applications approximately 14 days prior to planting
Precautions To help avoid rotational crop injury make applications as early as
possible since Boundary impregnated onto dry bulk fertilizers can be expected to last
longer in the soil than Boundary applied as a spray in water or fluid fertilizer

many surface applied herbicides weed control and crop tolerance may vary with rainfall
and/or soil texture
Grazing and Feeding Treated Soybean Plants
Treated soybean plants may be grazed or fed to livestock 40 days after the last
application of Boundary
Rate Ranges
Where a rate range is shown use a lower rate on soils that are coarse textured and/or
low in organic matter Use a higher rate on soils that are relatively fine textured and/or
high in organic matter
Replanting
If replanting is necessary in fields previously treated with Boundary the field may be
replanted to soybeans A minimum of tillage is recommended Do not apply a second
treatment as injury to soybeans may occur
Special Precautions (Soybeans)
Injury to soybeans or reduced weed control may occur when Boundary is used under
the following conditions these conditions should be avoided wherever possible
1 When soils have a calcareous surface area or a pH of 7 5 or higher
2 Due to the sensitivity of certain soybean varieties Boundary is not recommended
for use on Altona AP 55 AP 71 Asgrow6520 Burlison Coker102 Coker156

Vmton 81 If you choose to plant a newly released soybean variety consult your
seed supplier for information on its tolerance to metnbuzm (an active ingredient
in Boundary) before using Boundary
3 When applied in conjunction with soil applied organic phosphate pesticides
4 Uneven application or improper incorporation of Boundary can decrease the level
of weed control and/or increase the level of crop injury
5 When applied to any soil with less than 0 5% organic matter
6 Where soil incorporation is deeper than recommended
7 When sprayers were not calibrated accurately
8 When heavy rams occur soon after application especially in poorly drained areas
where water may stand for several days
9 When soybeans are planted less than 1 1/2 deep particularly when Boundary is
applied preemergence
10 Where high soil levels of atrazme are present
11 When using poor quality soybean seed
Boundary when applied as directed will control the following weeds

BOUNDARY FOUNDATION PROGRAM FOR PLANNED 2 PASS WEED CONTROL
SYSTEMS
Boundary may be applied preplant incorporated or preemergence at 1 25 1 5 pts /A on
all soils to reduce competition from the weeds listed in Table 2 for a 30 day period when
followed by a planned postemergence weed control treatment Recommended
postemergence treatments include any product or combination of products labeled to
control the specific weeds remaining in the field including Roundup® and Roundup
Ultra™ (for use on Roundup Ready® soybean varieties) Follow all application
directions for Boundary used alone either preplant incorporated or preemergence For
the postemergence herbicide application consult the selected postemergence herbicide
manufacturer s label for weeds controlled weed size application rate additional use
directions precautions and limitations before use
Note On soils with pH above 7 0 use the 1 25 pts /A rate only
BOUNDARY IN CONVENTIONAL TILLAGE SYSTEMS
Preplant Incorporated Application
Incorporate Boundary uniformly into the top 2 inches of soil within 14 days before
planting using a disk field cultivator rolling cultivator or similar implement Apply
Boundary preplant incorporated if furrow irrigation is used or when a period of dry
weather after application is expected If soybeans are planted on beds apply and
incorporate the tank mixture after bed formation
Preemergence Application
Dry weather following preemergence application of Boundary may reduce effectiveness
If weeds develop cultivate uniformly with shallow tilling equipment such as a rotary hoe
that will not damage soybeans

Use low rate range for low residue level or soils with less than 3% organic matter Use
the higher rate range for high residue level or soils with greater than 3% organic
matter
2Do not use on sand soils On coarse textured soils do not use on loamy sand soils
with less than 2% organic matter
3Silty clay loam soils are transitional soils and may be classified as medium textured
soils in some regions of the U S When using Boundary treat this soil as fine
textured
BOUNDARY SEQUENTIAL APPLICATION
An early preplant (surface applied or shallow incorporated) application of Boundary
followed by a preemergence application of Boundary after planting but before soybean
emergence will provide more consistent control of broadleaf and grass weeds than a
single application
A sequential application will decrease the need for tillage and/or burndown herbicides
for the control of existing vegetation before planting while providing residual control of
weeds after planting
Application
An early preplant application may be made 15 30 days before planting soybeans
Follow this application with a preemergence overlay application of Boundary after
planting but before crop emergence Follow directions on this label for sequential
applications from 0 14 days before planting
29
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 and
preemergence overlay applications approaches the maximum 30 days (c) when the
organic matter content of the soil is over 3% and/or (d) when heavy crop residues are
present on the soil surface
When weeds exceed 1 1 5 inches in height or diameter at application use a burndown
herbicide such as Roundup Ultra Gramoxone Extra or 2 4 D LVE
Weeds Controlled In addition to weeds controlled by Boundary alone the sequential
application improves control of the following annual broadleaf weeds buffalobur
cocklebur common ragweed velvetleaf and sunflower

Environmental Hazards
Do not apply directly to water to areas where surface water is present or to mtertidal
areas below the mean high water mark Do not contaminate water when disposing of
equipment wash water or rinsate
Ground Water Advisory
S metolachlor has the potential to leach through soil into ground water under certain
conditions as a result of agricultural use Use of this chemical in areas where soils are
permeable particularly where the water table is shallow may result in ground water
contamination
34
Metnbuzm is a chemical which can travel (seep or leach) through soil and can
contaminate ground water which may be used as drinking water Metnbuzm has been
found in ground water as a result of agricultural use Users are advised not to apply
metnbuzin where the water table (ground water) is close to the surface and where the
soils are very permeable i e well drained soils such as loamy sands Your local
agricultural agencies can provide further information on the type of soil in your area and
the location of ground water
Surface Water Advisory
S metolachlor has the potential to contaminate surface water through ground spray drift
Under some conditions S metolachlor may also have a high potential for runoff into
surface water (primarily via dissolution in runoff water) for several months post
application These include poorly draining or wet soils with readily visible slopes toward
adjacent surface waters frequently flooded areas areas overlaying extremely shallow
ground water areas with in field canals or ditches that dram to surface water areas not
separated from adjacent surface waters with vegetated filter strips and areas overlaying
tile drainage systems that dram to surface water
