Subject: Label Amendment
EPA Reg. No.: 7969-146/Guardsman Herbicide
EPA Receipt Date: September 10, 2004
Dear Dr. Kleppe:
OFFICE OF
PREVENTION. PESTICIDES AND
TOXIC SUBSTANCES
OCT 1 4 ;,'U04
The labeling referred to above, submitted in connection with registration under the Federal
Insecticide, Fungicide, and Rodenticide Act, as amended, is acceptable provided you make the
following label changes.
I. On page 4, the statement, "Reusable containers ... " must be changed to "This container must
only be refilled with a pesticide product. Do Not Reuse the Container for Any Other Purpose.
Cleaning is not necessary prior to refilling with the same product. However, if the container is
refilled with another pesticide product, the container must be cleaned according to written
instructions provided by BASF prior to refilling. Do not transport if the container is damaged or
leaking. To obtain information about recycling refillable containers or if a container that is
dedicated to BASF is damaged or leaking, contact BASF Corporation at 1-800-551-CROP.
Cleaning and final disposal of this container must be in compliance with State and local
regulations.
2. On page 6, revise the section under the heading, "Managing Off-target Movement", to be
consistent with your other dimethenamidlatrazine products. The section should be revised as
outlined:
"Spray Drift:
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction
of many equipment-and-weather-related factors determine the potential for spray drift. The
applicator and the grower are responsible for considering all these factors when making
decisions. Spray drift from applying this product may result in damage to sensitive plants
adjacent to the treatment area. Only apply this product when the potential for drift to these and
other adjacent sensitive areas (e.g. residential areas, bodies of\\uter, known habitat for
threatened or endangered species. or non-target crops) is minimal. Do not apply when the
following conditions exist that increase the likelihood of spray drift from intended targets: high
or gusty winds, high temperatures, low humidity, temperature inversions. To minimize spray
drift, the applicator should be familiar with and take into account the following drift reduction
advisory information. Additional information may be available from state enforcement agencies
or the Cooperative Extension on the application of this product.".
"Information On Droplet Size"
'The best drift management strategy and most effective way to reduce drift potential are to apply
large 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 manufacture'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 recommended practice. Significant
deflection from the 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. Do not use
nozzles producing a mist droplet spray."
"Application Height"
"Making applications at the lowest possible height (aircraft, ground driven spray boom) that is
safe and practical 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 application equipment (e.g. aircraft. ground) upwind.
Swath adjustment distance should increase with increasing drift potential (higher wind, smaller
droplets, etc.)."
"Wind"
"Drift potential is lowest between wind speeds of 3-1 0 mph. However, many factors, including
droplet size and equipment type, determine drift potential at any given speed. Application should
be avoided below 3 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 ho\\' 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 temperature inversions because drift potential is high.
Temperature inversions restrict vertical air mixing, which causes small suspended droplets to
remain in a concentrated cloud, which 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, iffog 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."
"Managing Spray Drift From Aerial Applications"
"Applicators must follow these requirements to avoid off-target drift movement: 1. Boom
length- the distance of the outermost nozzles on the boom must not exceed 3/4 the length of the
wingspan or rotor, 2. Nozzle orientation- nozzles must always point backward parallel with the
air stream and never be pointed downwards more than 45 degrees, and 3. Application height­
without compromising aircraft safety, applications should be made at a height of 10 feet or less
above the crop canopy or tallest plants. Applicators must follow the most restrictive use cautions
to avoid drift hazards, including those found in this labeling as well as applicable state and local
regulations and ordinances."
Keep the section "Wind Erosion of treated soil"
3 On your label after the phrase "on highly erodible soils", add (as defined by the Natural
Resource Conservation Service).
4. On page 7 , add "bulk" to "On-farm fertilizer impregnation is prohibited" to read "On-farm
bulk fertilizer impregnation is prohibited."
5. On page 6, under Tank Mix Partners/Components add a statement "The total pounds of
atrazine applied from all sources must not exceed 2.5 pounds of active ingredient per acre per
year
Amended labeling will supercede all previous accepted ones. A stamped copy of labeling is

Environmental Hazards
Do not discharge effluent containing this product into
lakes, streams, ponds, estuaries, oceans, or other
waters unless in accordance with the requirements of
a National Pollutant Discharge Elimination System
(NPDES) pemnit and the permitting authority has been
notified in writing prior to discharge. Do not
discharge effluent containing this product to sewer
systems without previously notifying the local sewage
treatment plant authority. For guidance, contact your
State Water Board or Regional Office of the EPA.
Ground and Surface Water Advisory
Dimethenamid-P has properties that may result in
groundwater contamination. Application in areas
where soils are permeable or coarse and groundwater
is near the surface could result in groundwater
contamination. Following application and during
rainfall events that cause run-off, this chemical may
reach surface water bodies including streams, rivers,
and reservoirs.
Guardsman contains the active ingredient
atrazine. Atrazine can travel (seep or leach) through
soil and can enter ground water which may be used
as drinking water. Atrazine has been found in ground
water. Users are advised not to apply atrazine to
sand and loamy soils where the water table (gound
water) is close to the surface and where these soils
are very permeable; i.e., well drained. Your local
agricultural agencies can provide further information
on the type of soil in your area and the location of
ground water.
o This product must not be mixed, loaded, or used
within 50 ft. of all wells including abandoned wells,
drainage wells, and sinkholes. Operations that
involve mixing, loading, rinsing, or washing of this
product into or from pesticide handling or
application equipment or containers within 50 ft. of
any well are prohibited, unless conducted on an

Guardsman should be used in tank mixes or sequential applica~
tions with other herbicides that provide additional control of these
weed species.
I For best control of these species, use the highest rate recom­
mended by soil type. If dry conditions exist near application or
excessive rainfall occurs ear'Y in season, a postemergence herbi­
cide or cultivation may be required to help control these weeds.
Mode of Action
Guardsman contains two active ingredients:
dimethenamid, a root and shoot growth inhibitor,
Group 15, and atrazine, a photosynthetic inhibitor at
photo system II Site A. Group 5. Guardsman
typically controls weeds before or soon after they
emerge from the soil.
Herbicide Resistance
Naturally occurring biotypes of certain pests with
resistance to the atrazine component in Guardsman
are known to exist. Selection of resistant biotypes,
through repeated use of atrazine or related triazine
herbicides (same mode of action), may result in
control failures. If poor performance cannot be
attributed to adverse weather conditions or improper
application methods, a resistant biotype may be
present. In such a case, additional treatments with
this herbicide or related products is not
recommended. Consult your local representative or
agricultural advisor for assistance.
Cleanin!il Spray Equipment
Clean application equipment thoroughly by using a
strong detergent or commercial sprayer cleaner
according to the manufacturer's directions and then
triple rinsing the eqUipment before and after applYing
this product.

(
II. Application Instructions
Guardsman may be applied preplant surface,
preplant incorporated, pre-emergence or may be
applied early postemergence to corn or grain
sorghum. Guardsman will provide most effective
weed control when applied (by ground or aerial
equipment), and subsequently incorporated into soil
by rainfall, sprinkler irrigation, or mechanical tillage
prior to weed seedling emergence from soil.
Guardsman may be applied using either water or
fluid fertilizer as the spray carrier, or impregnated onto
and applied with dry bulk fertilizer. Sprayable fluid
fertilizer as a carrier is not recommended for use after
crop emergence. Refer to section III. Additives for
more information.
Application Rate
Recommended use rates for Guardsman when
used alone, in tank mix, or sequential applications are
given in Table 2 (reler to section IV. General Tank
Mixing Information and section VI. Crop-Specific
Information for more details). Recommended use
rates of this product vary by soil type. The most
accurate indicator of appropriate use rate for
Guardsman is the Cation Exchange Capacity (CEC)
of the soil to be treated. CEC values are available in
standard soil testing procedures. If CEC values are
not available, the recommended use rate of
Guardsman may be determined using soil texture
and organic matter. Soil texture groupings used in this
label are coarse (sand, loamy sand, sandy loam),
medium (silt, silt loam, loam, sandy clay loam), and
fine (sandy clay, silty clay, silty clay loam, clay loam,
and clay).
To determine Guardsman use rates by either soil
CEC values or by soil texture and organic matter, refer
to Table 2. When use rates are expressed in ranges,
use the lower rates for lower CEC values and use the
higher rates for higher CEC values. If soil texture and
organic matter content are used to determine use
rates, use the lower rates for more coarsely textured
soils low in organic matter and use the higher rates
for more finely textured soils that are high in organic
matter. Reduced rates may be used where partial
control or reduced length of soil residual control is
required (refer to Table 2).

as postemergence applications, or pre-emergence
applications where cultivation or sequentially applied
herbicides will be used for added control of the same
targeted weed species. Use 2-2.5, 2.5-3, and 3-3.5
pints of Guardsman per acre on coarse, medium, and
fine soil respectively.
2 For all early preplant applications, use 4.75-5 pints of
Guardsman per acre. Do not exceed 4.75 pints per
acre on highly erodible soils with less than 30% plant
residue cover prior to crop emergence.
J On all soils with 8-20% organic matter, use 4.75-5 pints
of Guardsman per acre. Guardsman is not recom­
mended for use on soils with more than 20% organic
matter. L-___________________________ ____
Application Timing
Preplant Surface Applications; For use in
minimum tillage or no-tillage production systems.
apply Guardsman alone or in tank mixes up to 45
days before planting. When making early preplant
applications (15-45 days prior to planting), use the
highest rate recommended for the specific soil type.
Early preplant applications are not recommended for
use on coarse-textured soils or in areas where
average annual rainfall (or rainfall + irrigation) typically
exceeds 40". Early preplant applications may be
applied as part of a split application program where
the second application is made after olanting (use
2/3 of Guardsman" herbicide rate early followed
by 1/3 of rate after planting). A split application is
recommended when the initial application is made
more than 30 days prior to planting. Tank mixes with
postemergence herbicides such as Acquire'",
Clarity", Gramoxone" Extra, Roundup Ultra", or
Touchdown" must be used when weeds are more
than 1.5" tall at the time of application.
Preplant Incorporated Applications; Apply
Guardsman and incorporate into the upper (1-2")
soil surface up to 2 weeks before planting. Use a
harrow, rolling cultivator, finishing disk, or other
Implement capable of giving uniform shallow
incorporation. Avoid deeper incorporation or
reduced weed control may result.
6
(
Pre-emergence Surface Applications; Broadcast
treatment uniformly to the soil surface after planting
and before crop emergence. Rainfall, sprinkler
irrigation, or shallow mechanical incorporation after
application is required to move this product into the
upper soil surface where weed seeds germinate. If
adequate rainfall or irrigation does not occur and
weed seedling emergence begins, a shallow
cultivation or rotary hoeing will improve performance.
Earlv Postemergence Applications; Guardsman
may be applied early postemergence to corn or
sorghum up to 12" tall. Apply Guardsman before
weeds are greater than 1.5" tall or in a tank mix with
products that control emerged weeds.
Split Applications; Guardsman may be used in
split application programs where applications are
made as part of the methods described above. If
applications are less than 2 weeks apart, the total
Guardsman rate used must not exceed the
maximum rate given for each specific soil type. If
applications are 2 weeks or more apart, a total
Guardsman use rate of up to 5 pints per acre per
year may be used on any soil type.
Managing Off-target Movement
Sprav Oritt; High or gusty winds, high temperatures,
low humidity, and temperature inversions increase the
likelihood of spray drift from intended targets. Do not
apply when these conditions exist. To minimize spray
drift:
• Make application when conditions are favorable for
even spray deposition (approximately 3-10 mph)
on the soil surface. Do not apply when wind or
wind gusts exceed 15 mph.
• Use low pressure, properly calibrated, application
equipment as possible to produce large spray
droplets and sufficient spray volume to ensure
uniform application. Do not use nozzles producing
a mist droplet spray.
• Keep ground driven spray boom as low as
possible above the target surface.
Wind erosion of treated soil; Avoid treatin(l
powdery dry or light sandy soils when conditions are
favorable for wind erosion. Under these conditions,
the soil surface should first be settled by rainfall or
irrigation.
Aerial Application Methods and
Equipment
Water Volume; Use 2 or more gallons of water per
acre. The actual minimum spray volume per acre is
determined by the spray equipment used. Adequate
spray volume must be used to provide accurate and
uniform distribution of spray particles over the treated
area and to avoid drift of spray particles to nontarget
areas.
Application Equipment; Use nozzle screens no finer
than 50 mesh. The applicator must follow the most
restrictive use cautions to avoid drift hazards,
including those found in this labeling as well as
applicable state and local regulations and ordinances.
----- ----
Ground Application (Bandin~)
When applying Guardsman by banding, determine
the amount of herbicide and water volume needed
using the following formula:
Bandwidth ~n inches X Broadcast rate = Banding herbicide
Row width In Inches per acre rate per acre
Bandwidth in inches X Broadcast = Banding water
Row width in inches volume per acre volume per acre
Ground Application Methods and
Equipment (Broadcast)
Water Volume: Use 2 or more gallons of water per
acre. The actual minimum spray volume per acre is
determined by the spray equipment used. Adequate
spray volume must be used to provide accurate and
uniform distribution of spray particles over the treated
area and to avoid drift of spray particles to nontarget
areas.
Application Equipment: Use nozzle screens no finer
than 50 mesh.
Ground Application (Dry Bulk Fertilizer)
Guardsman may be impregnated or coated onto dry
bulk granular fertilizer carriers for preplant surface,
preplant incorporated, or pre-emergence applications.
Impregnation of bulk fertilizer is restricted to
commercial facilities. On-farm fertilizer impregnation is
prohibited. No more than 500 tons of dry bulk fertilizer
can be impregnated per day. No single facility may
impregnate fertilizer with this product for more than
30 days per calendar year. The commercial facility
impregnating the dry bulk fertilizer must inform, in
writing, the user (applicator) of the dry bulk fertilizer
that:
• Applicators must wear long-sleeved shirt, long
pants, shoes and socks.
• The restricted-entry interval is 12 hours.
Impregnation or coating may be conducted by either
the in-plant bulk system or the on-board system.
Guardsman may also be applied in herbicide tank
mixes where the tank mix companion product is alsc
registered for these application systems. Individuals or
agents selling Guardsman in these application
systems are responsible for following all state and
local regulations regarding fertilizer and herbicide
blending. The addition of a drying agent may be
necessary if the fertilizer and herbicide blend is too
wet for uniform application due to high humidity, high
urea concentration, or low fertilizer use rate. Slowly
add the drying agent to the blend until a fiowable
mixture is obtained. Drying agents are not
recommended for use with on-board impregnation
systems. Under some conditions, fertilizer
impregnated with Guardsman may clog air tubes or
defiector plates on pneumatic application systems.
Mineral oil may be added to Guardsman before
blending with fertilizer to reduce plugging. Do not use
drying agents when mineral oil is used. To avoid
separation of Guardsman and mineral oil mixes in
cold temperatures, either keep mixture heated or
agitated prior to blending with fertilizer. Mineral oil may
be used at in-plant blending stations or on-board
injection systems.
7
('
Apply 200-750 pounds of fertilizer and herbicide
blend per acre. Application must be made uniformly
to the soil to prevent possible crop injury and offer
satisfactory weed control. Impregnated fertilizer
spread at half rate and overlapped to obtain a full rate
will offer a more uniform distribution. A shallow (1-2")
incorporation is desirable for improved weed control.
Deeper incorporation may result in unsatisfactory
weed control.

Do not impregnate Guardsman or Guardsman
mixes on ammonium nitrate, potassium nitrate, or
sodium nitrate fertilizers or fertilizer blends. Single
superphosphate (0-20-0) and triple superphosphate
(0-46-0) may be impregnated only with Guardsman
alone.
III. Additives
Spray adjuvants have little or no influence on
performance of Guardsman when applications are
made prior to weed emergence. To improve
burndown of emerged weecs, surfactants or low-rate
fertilizer (28%, 30%, or 32% UAN or ammonium
sulfate), or crop oil concentrate may be used with
Guardsman alone or in tank mixes applied preplant,
pre-emergence, or early postemergence to the crop.
Consult your local BASF representative for
recommendations for your area.
Nitrogen Source
• Urea ammonium nitrate (UAN): Use 2-4 quarts
of UAN (commonly referred to as 28%, 30%, or
32% nitrogen solution) per acre. Do not use brass
or aluminum nozzles when spraying UAN.
• Ammonium sulfate (AMS): AMS at 2.5 pounds
per acre may be subslrtuted for UAN. Use high­
quality AMS (spray grade) to avoid plugging of
nozzles. Other sources of nitrogen are not as
effective as those mentioned. BASF does not
recommend applying AMS if applied in less than
10 gallons per acre because of potential problems
with precipitation in reduced volumes. Use AMS
only if it has been demonstrated to be successful
in local experience.
Nonionic Surfactant
The standard label recommendation is 1 pint of an
80% active nanionic spray surfactant per 100 gallons
of water.
Oil Concentrate
Crop oil concentrates are allowec after crop
emergence only when Guardsman is used alone or
in tank mixes with atrazine. See the manufacturer's
label for specific rate recommendations. A crop oil
concentrate must contain either a petroleum or
vegetable oil base and must meet all of the following
criteria:
• be non phytotoxic,
• contain only EPA-exempt ingredients,
• provide good mixing quality in the jar test, and
• be successful in local experience.
The exact composition of suitable products will vary;
however, vegetable and petroleum oil concentrates
should contain emulsifiers to provide good mixing
quality. Highly refined vegetable oils have proven more
satisfactory than unrefined vegetable oils. For
additional information, see Compatibility Test for
Mix Components.

Physical incompatibility, reduced weed control, or
crop injury may result from mixing Guardsman with
other pesticides (fungicides, herbicides, insecticides,
or miticides), additives, or fertilizers. BASF does not
recommend using tank mixes other than those listed
on BASF labeling. Local agricultural authorities may
be a source of information when using other than
BASF recommended tank mixes.
Compatibility Test for Mix Components
Before mixing components, always perform a
compatibility jar test.
For 20 gallons per acre spray volume, use 3.3 cups
(800 ml) of water. For other spray volumes, adjust
rates accordingly. Only use water from the intended
source at the source temperature.
Add components in the sequence indicated in the
Mixing Order using 2 teaspoons for each pound or
1 teaspoon for each pint of recommended label rate
per acre.
Always cap the Jar and invert 10 cycles between
component additions.
When the components have all been added to the jar,
let the solution stand for 15 minutes. Evaluate the
solution for uniformity and stability. The spray solution
should not have free oil on the surface, nor fine
particles that precipitate to the bottom, nor thick
(clabbered) texture. If the spray solution is not
compatible, repeat the compatibility test with the
addition of a suitable compatibility agent. If the
solutior is then compatible, use the compatibility
agent BS directed on its label. If the solution is still
incompatible, do not mix the ingredients In the same
tank .
Mixin~ Order
1) Water. Begin by agitating a thoroughly clean
sprayer tank three-quarters full of clean water.
2) Agitation. Maintain constant agitation throughout
mixing and application.
3) Inductor. If an inductor is used, rinse it thoroughly
after each component has been added.
4) Products in PYA bags. Place any product
contained in water-soluble PVA bags into the
mixing tank. Wait until all water-soluble PVA bags
have fully dissolved and the product is evenly
mixed in the spray tank before continuing.
5) Water-dispersible products (such as
Guardsman, dry flowables, wettable powders,
suspension concentrates, or sus po-emulsions).
6) Water-soluble products.
7) Emulsifiable concentrates (oil concentrate when
applicable).
8) Water-soluble additives (such as AMS or UAN
when applicable).
9) Remaining quantity of water.
Maintain constant agitation during application.

User Safety Recommendations:
• Users should wash hands before eating, drinking, chewing gum, using tobacco,
or using the toilet.
• Users should remove clothing/PPE immediately if pesticide gets inside. Then
wash thoroughly and put on clean clothing.
• Users should remove PPE immediately after handling this product. Wash the
outside of gloves before removing. As soon as possible, wash thoroughly and
change into clean clothing.
Environmental Hazards
• Atrazine can travel (seep or leach) through soil and can enter ground water which may
be used as drinking water. Atrazine has been found in ground water. Users are advised
not to apply atrazine to sand and loamy sand soils where the water table (ground water)
is close to the surface and where these soils are very permeable; i.e., well-drained. Your
local agricultural agencies can provide further information on the type of soil in your area
and the location of ground water.

Environmental Hazards (continuec/j
• Product must not be mixed or loaded, or used within 50 feet of all wells, including
abandoned wells, drainage wells, and sink holes. Operations that involve mixing,
loading, rinsing, or washing of this product into or from pesticide handling or application
equipment or containers within 50 ft. of any well are prohibited, unless conducted on an
impervious pad constructed to withstand the weight of the heaviest load that may be
positioned on or moved across the pad. Such a pad shall be designed and maintained
to contain any product spills or equipment leaks, container or equipment rinse or wash
water, and rain water that may fall on the pad. Surface water shall not be allowed to
either flow over or from the pad which means the pad must be self-contained. The pad
shall be sloped to facilitate material removal. An unroofed pad shall be of sufficient
capacity to contain at a minimum 11 0% of the capacity of the largest pesticide container
or application equipment on the pad. A pad that is covered by a roof of sufficient size to
completely exclude precipitation from contact with the pad shall have a minimum
containment of 1 00% of the capacity of the largest pesticide container or application
equipment on the pad. Containment capacities as described above shall be maintained
at all times. The above-specified minimum containment capacities do not apply to
vehicles when delivering pesticide to the mixing/loading sites.
• Additional State imposed reqUirements regarding well-head setbacks and operational
area containment must be observed.
• Product must not be mixed or loaded within 50 feet of intermittent streams and rivers,
natural or impounded lakes and reservoirs. Product must not be applied within 66 feet
of pOints where field surface water runoff enters perennial or intermittent streams and
rivers or within 200 feet of natural or impounded lakes and reservoirs. If this product is
applied to highly erodible land, the buffer or setback from runoff entry points must be
planted to crop, or seeded with grass or other suitable crop.
• This pesticide is toxic to aquatic invertebrates. Do not apply directly to water, to areas
where surface water is present, or to intertidal areas below the mean high water mark.
Do not apply when weather conditions favor drift from treated areas. Runoff and drift
from treated areas may be hazardous to aquatic organisms in neighboring areas. Do
not contaminate water when cleaning equipment or disposing of equipment wash water.
