Precautionary Statements
Hazards to Humans and Domestic Animals
CAUTION. Harmful if swallowed or absorbed through skin.
Causes moderate eye irritation. Avoid contact with eyes,
skin, or clothing. Prolonged or frequently repeated skin
contact may cause allergic reactions in some individuals.
Personal Protective Equipment (PPE)
Applicators and other handlers must wear:
• Long-sleeved shirt and long pants
• Waterproof gloves
• Shoes plus socks
Follow the manufacturers instructions for cleaning and
maintaining PPE. If no such instructions for washables
exist, use detergent and hot water. Keep and wash PPE
separately from other laundry.
Engineering Controls
When handlers use closed systems, enclosed cabs, or air-
craft in a manner that meets the requirements listed in the
Worker Protection Standard (WPS) for agricultural
pesticides [40 CFR 170.240(d)(4-6)], the handler PPE
requirements may be reduced or modified as specified in
the WPS.
Environmental Hazards
For terrestrial uses, DO NOT apply directly to water, or to
areas where surface water is present, or to intertidal areas
below the mean high water mark. DO NOT contaminate
water when disposing of equipment washwater or rinsate.
Bentazon, which is present in this product, is known to
leach through soil into groundwater under certain condi-
tions 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 groundwater
contamination.
Bentazon can affect non-target plant species outside the
treatment area. To limit adverse effects to non-target
plants, the applicator must avoid making applications when
wind can facilitate off-site movement of bentazon in direc-
tions of areas such as forested areas, riparian areas,
wetlands, and areas that serve as habitat for desirable and
protected animal species.
It is a violation of federal law to use any pesticide in a man-
ner that results in the death of an endangered species or in
adverse modification of their habitat.
Pollinator Advisory Statement. This product may
adversely impact the forage and habitat of local pollinators,
including the monarch butterfly (and its larvae), birds, or
bats if it reaches non-target areas. Protect pollinators by
following label directions to minimize spray drift.
Directions For Use
It is a violation of federal law to use this product in a man-
ner inconsistent with its labeling.
DO NOT apply this product in a way that will contact
workers or other persons, either directly or through drift.
Only protected handlers may be in the area during applica-
tion. For any requirements specific to your state or tribe,
consult the agency responsible for pesticide regulation.
USER SAFETY RECOMMENDATIONS
Users should:
• Wash hands before eating, drinking, chewing gum,
using tobacco, or using the toilet.
• Remove clothing/PPE immediately if pesticide gets
inside. Then wash thoroughly and put on clean clothing.
• 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.

Product Information
Basagran® herbicide is intended for selective
postemergence control of certain broadleaf weeds and
sedges in alfalfa grown for seed, beans, clover grown for
seed, corn, nonbearing foods crops, peanuts, peas,
peppermint, rice, sorghum, soybeans, and spearmint.
Basagran does not control grasses.
Mode of Action
Bentazon, the active ingredient in Basagran, is a Group 6
(WSSA) herbicide belonging to the benzothiadiazinone
chemistry class. Basagran inhibits photosynthesis at
photosystem II site B resulting in symptoms of chlorosis
that progresses to necrosis and control of emerged weeds.
Herbicide Resistance Management
Basagran is a Group 6 herbicide. Any weed population
may contain or develop plants naturally resistant to
Basagran and other Group 6 herbicides. Weed species
with resistance to Group 6 may eventually dominate the
weed population if Group 6 herbicides are used repeatedly
in the same area or in successive years as the primary
method of control for targeted species. This may result in
partial or total loss of control of those species by
Basagran or other Group 6 herbicides.
To delay herbicide resistance consider:
• Avoiding the consecutive use of Basagran or other
target- site-of-action Group 6 herbicides that have a simi-
lar target site of action on the same weed species.
• Using tank mixes or premixes with herbicides from differ-
ent target-site-of-action groups as long as the involved
products are all registered for the same use, have differ-
ent sites of action, and are both effective at the tank mix
or prepack rate on the weed(s) of concern.
• Basing herbicide use on a comprehensive IPM
(Integrated Pest Management) program including cultural
and mechanical methods.
• Monitoring treated weed populations for loss of field effi-
cacy, and control of escapes with effective alternative
herbicides or mechanical methods.
• Identify weeds present in the field through scouting and
field history and understand their biology. The weed-
control program needs to consider all of the weeds
present.
• Scout fields prior to application to identify the weed
species present and their growth stage to determine if
the intended application will be effective.
• Scout fields after application to verify the treatment was
effective.
• Suspected herbicide-resistance weeds may be identified
by these indicators:
1. Failure to control a weed species normally controlled
by the herbicide at the dose applied, especially if con-
trol is achieved on adjacent weeds;
2. A spreading patch of non-controlled plants of a partic-
ular weed species; and
3. Surviving plants mixed with controlled individuals of the
same species.
• If resistance is suspected, treat weed escapes with an
herbicide with a different MOA and/or use nonchemical
methods to remove escapes, as practical, with the goal
of preventing further seed production.
• Report any incidence of non-performance of this product
against a particular weed species to your local BASF rep-
resentative.
• Contacting your local extension specialist, and/or manu-
facturer for herbicide resistance management and/or
integrated weed management directions for specific
crops and resistant weed biotypes.
Crop Tolerance
All labeled crops are tolerant to Basagran. Leaf speckling
or bronzing may occur, but plants generally outgrow this
condition within 10 days. New growth is normal and crop
vigor is not reduced.
Application Instructions
Apply Basagran postemergence to small, actively growing
weeds early in the season for the most effective control as
broadcast, band, or spot spray applications. Delaying
application permits weeds to exceed the specified maxi-
mum size and will prevent adequate control.
Apply the specified rates of Basagran to actively growing
weeds before they reach the maximum sizes listed in
Table 1. Application Rates and Weeds Controlled in
All Crops Except Rice, in Table 3. Application Rates
and Weeds Controlled in Rice - Flooded Fields, and in
Table 4. Application Rates and Weeds Controlled in
Rice - Drained Fields.
Irrigation
In irrigated areas, it may be necessary to irrigate before
treatment to ensure active weed growth because weeds
growing under drought conditions usually are not satisfac-
torily controlled.
4
Cultivation
DO NOT cultivate within 5 days before applying or within
7 days after applying Basagran® herbicide. Timely culti-
vation after 7 days may help provide season-long weed
control.
Application Methods and Equipment
Basagran may be applied by ground or air. Thorough
spray coverage is required for optimum control of emerged
weeds and can be improved with proper adjuvant, nozzle,
and spray volume selection. Use and configure application
equipment for adequate spray volume, accurate and uni-
form distribution of spray droplets over the treated area,
and to avoid spray drift to non-target areas. Adjust equip-
ment to maintain continuous agitation during spraying with
good mechanical or bypass agitation. Avoid overlaps that
will increase rates above use rates specified in this label.
Dense leaf canopies shelter smaller weeds and can prevent
adequate spray coverage. Early season application to small
weeds makes thorough spray coverage easier to obtain.
Aerial Application Requirements
Water Volume. Use a minimum spray volume of 5 gallons
of water per acre.
Nozzles must always point backward parallel with the
airstream and never point downward more than
45 degrees.
Avoid potential adverse effects to non-target areas by
maintaining a 20-foot buffer between the point of direct
application and the closest downwind edge of sensitive
terrestrial habitats (such as grasslands, forested areas,
shelter belts, woodlots, hedgerows, riparian areas, and
shrub lands).
Special Directions for Aerial Application
• DO NOT apply Basagran by air if sensitive crops (such
as cotton, sugar beets, sunflowers, or okra) are within
200 feet downwind.
Ground Application Requirements
Water Volume. Use a minimum spray volume of 10 gal-
lons of water per acre to ensure adequate spray coverage.
Use higher spray volume (up to 20 gallons of water per
acre) to improve spray coverage when crop and weed
foliage is dense.
Avoid potential adverse effects to non-target areas by
maintaining a 10-foot buffer between the application area
and the closest downwind edge of sensitive terrestrial
habitats (such as grasslands, forested areas, shelter belts,
woodlots, hedgerows, riparian areas, and shrub lands).
Special Directions for Ground Application
• DO NOT use flood, whirl chamber, or controlled droplet
applicator (CDA) nozzles or selective application equip-
ment such as recirculating sprayers or wiper applicators.
• DO NOT use brass nozzles because of the corrosive
effects of nitrogen additives.
Spray Drift Advisories
It is the responsibility of the applicator to avoid spray drift at
the application site, especially onto non-target areas. The
interaction of many equipment and weather-related factors
determines the potential for spray drift. The applicator is
responsible for considering all these factors when making
application decisions.
Importance of Droplet Size
The most effective way to reduce drift potential is to apply
the largest droplets that provide sufficient coverage and
control. The presence of sensitive species nearby, the envi-
ronmental conditions, and pest pressure may affect how
an applicator balances drift control and coverage. APPLY-
ING LARGER DROPLETS REDUCES DRIFT POTENTIAL,
BUT WILL NOT PREVENT DRIFT IF APPLICATIONS ARE
MADE IMPROPERLY OR UNDER UNFAVORABLE ENVI-
RONMENTAL CONDITIONS. See Wind; Temperature
and Humidity; and Temperature Inversion sections of
this label.
Mandatory Spray Drift Management
Aerial Applications
• When applying aerially to crops, do not release spray at
a height greater than 10 ft above the crop canopy,
unless a greater application height is necessary for pilot
safety.
• Applicators are required to select nozzles that deliver
medium or coarser spray droplets in accordance with
ANSI/ASABE S641 May 2018.
• When applying to crops via aerial application
equipment, the spray boom must be mounted on the
aircraft so as to minimize drift caused by wing tip or
rotor blade vortices. The boom length must not exceed
75% of the wingspan or 90% of the rotor blade
diameter.
• When applying to crops via aerial application
equipment, applicators must use 1/2 swath displace-
ment upwind at the downwind edge of the field.
• Nozzles must be oriented, so the spray is directed
toward the back of the aircraft.
• DO NOT apply when wind speeds exceed 10 mph at
the application site.
• DO NOT apply during temperature inversions.
Ground Boom Applications
• When using ground application equipment, apply with
nozzle height no more than 4 ft above the ground or
crop canopy applications.
• Applicators are required to select nozzles that deliver
medium or coarser spray droplets in accordance with
ANSI/ASAE S572.3 Feb 2020.
• DO NOT apply when wind speeds exceed 10 mph at
the application site.
• DO NOT apply during temperature inversions.
5
Controlling Droplet Size - Ground Boom
• Volume - Use high flow rate nozzles to apply the highest
practical spray volume. Nozzles with higher rated flows
produce larger droplets.
• Pressure - Use the lower spray pressures recommend-
ed for the nozzle. Higher pressure reduces droplet size
and does not improve canopy penetration. WHEN
HIGHER FLOW RATES ARE NEEDED, USE A HIGHER
CAPACITY NOZZLE INSTEAD OF INCREASING
PRESSURE.
• 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.
Controlling Droplet Size - Aircraft
• Number of Nozzles - Use the minimum number of noz-
zles with the highest flow rate that provide uniform
coverage.
• Nozzle Type - Solid stream nozzles (such as disc and
core with swirl plate removed) oriented straight back pro-
duce larger droplets than other nozzle types.
• Boom Length - Longer booms increase drift potential.
Therefore a shorter boom length is recommended.
• Nozzle Orientation - Orienting nozzles so that the spray
is emitted backwards, parallel to the airstream will pro-
duce larger droplets than other orientations. AVOIDING
SPRAY DRIFT IS THE RESPONSIBILITY OF THE
APPLICATOR.
• Application Height - Application more than 10 ft above
the canopy increases the potential for spray drift.
Boom Height
Setting the boom at the lowest referenced height (if speci-
fied) which provides uniform coverage reduces the
exposure of droplets to evaporation and wind. For ground
equipment, the boom must remain level with the crop and
have minimal bounce.
Wind
Drift potential increases at wind speeds of less than 3 mph
(due to inversion potential) or more than 10 mph. However,
many factors, including droplet size and equipment type
determine drift potential at any given wind speed. AVOID
APPLICATIONS DURING GUSTY OR WINDLESS
CONDITIONS.
Note: Local terrain can influence wind patterns. Every
applicator needs to be familiar with local wind patterns and
how they affect spray drift.
Temperature and Humidity
When making applications in hot and dry conditions, set up
equipment to produce larger droplets to reduce effects of
evaporation.
Temperature Inversion
Drift potential is high during a temperature inversion.
Temperature inversions restrict vertical air mixing, which
causes small suspended droplets to remain close to the
ground and move laterally in a concentrated cloud.
Temperature inversions are characterized by increasing
temperature with altitude and are common on nights with
limited cloud cover and light to no wind. They begin to form
as the sun sets and often continue into the morning. Their
presence can be indicated by ground fog; however, if fog
is not present, inversions can also be identified by the
movement of smoke from a ground source or an aircraft
smoke generator. Smoke that layers and moves laterally in
a concentrated cloud (under low wind conditions) indicates
an inversion, while smoke that moves upward and rapidly
dissipates indicates good vertical air mixing.
Shielded Sprayers
Shielding the boom or individual nozzles can reduce the
effects of wind. However, it is the responsibility of the appli-
cator to verify that the shields are preventing drift and not
interfering with uniform deposition of the product.
Cleaning Spray Equipment
Clean application equipment thoroughly by using a strong
detergent or commercial sprayer cleaner according to the
manufacturers directions, followed by triple rinsing the
equipment before and after applying Basagran
®
herbicide.
Runoff Prevention
To protect the environment, do not allow pesticide to enter
or run off into storm drains, drainage ditches, gutters or
surface waters. Applying this product in calm weather
when rain is not predicted for the next 24 hours will help to
ensure that wind or rain does not blow or wash pesticide
off the treatment area. Rinsing application equipment over
the treated area will help avoid run off to water bodies or
drainage systems.

Special Directions for Problem Weeds
Field and Hedge Bindweed - In the states of Kentucky, Illinois, Indiana, Michigan, and Ohio, apply 2 to 3 pints of
Basagran per acre when weeds are up to a maximum of 10-inches tall for suppression only.
Canada Thistle - Apply 2 pints of Basagran per acre when weeds are from 8-inches tall to the bud stage. Make a sec-
ond application at the same rate 7 to 10 days later.
Yellow Nutsedge - Apply 1.5 to 2 pints of Basagran per acre when weeds are up to a maximum of 8-inches tall. If
regrowth occurs, make a second application at the same rate 7 to 10 days later.
Treatment for Late Rescue of Cocklebur - Make a single application of 2 to 3 pints of Basagran per acre to weeds
up to 24-inches tall. For improved activity, apply 1.5 pints of Basagran per acre initially, and repeat application 10 to
14 days later.
Treatment for Late Rescue of Velvetleaf - Make a single application of 3 pints of Basagran per acre plus spray addi-
tives (an oil concentrate and UAN, refer to Additives section for more details) to weeds up to 12-inches tall. For
improved activity, apply 1.5 pints of Basagran per acre plus spray additives (an oil concentrate and UAN or AMS, refer to
Additives section for more details), followed by a second application at the same rate in 7 days.

Additives
To achieve consistent and optimum weed control, one of
or a combination of the following additives listed in
Table 2. Additive Rates must be added to the spray
tank. Additives may cause some leaf burn, but new growth
is normal and crop vigor is not reduced. The potential for
leaf burn is increased when relative humidity and tempera-
ture are high. When an adjuvant (or a specific adjuvant
product, such as a drift control agent) is to be used with
this product, BASF recommends the use of a Chemical
Producers and Distributors Association (CPDA) certified
adjuvant. See Table 2. Additive Rates. Applicators must
use the additive(s) that will provide the best performance
suited for their geography, target weed and environmental
conditions.
1 Petroleum-based or vegetable seed-based crop oil concentrate may be
used. The oil concentrate must be nonphytotoxic, contain only EPA-
exempt ingredients, provide good mixing quality in a jar test, and be
successful in local experience. The exact composition of suitable prod-
ucts will vary; however, petroleum-oil or vegetable-oil concentrates
should contain emulsifiers to provide good mixing quality. Highly refined
vegetable oils are more satisfactory than unrefined vegetable oils. To
determine the suitability of oil concentrates with Basagran
® herbicide,
conduct a jar test (see Tank Mixing Information section).
2 Methylated seed oil is recommended when weeds are under moisture or
temperature stress.
3 UAN may be added in place of other spray additives to improve control
of cocklebur, devilsclaw, Pennsylvania smartweed, velvetleaf, Venice
mallow, wild mustard, and wild sunflower. Basagran plus a nitrogen
solution will not provide adequate control of common ragweed and
common lambsquarters. If these weeds or other weeds requiring oil con-
centrate are present in addition to velvetleaf, then oil concentrate should
also be used.
Tank Mixing Information
Additives and/or other pesticides may be mixed in the
spray tank with Basagran according to the specific tank
mixing instructions in this label and respective product
labels.
See Crop-specific Information for more details. Read
and follow the applicable Restrictions and Limitations
and Directions For Use on all products involved in tank
mixing. The most restrictive labeling applies to tank mixes.
Physical incompatibility, reduced weed control, or crop
injury may result from mixing Basagran with other pesti-
cides (fungicides, herbicides, insecticides, or miticides),
additives, or fertilizers not specified on this label.
Jar Test to Estimate Oil Concentrate Suitability
Water Supply - Use only water from the intended source
at the source temperature.
Water Spray Volume - For a spray volume of 20 gallons
per acre, use 3.3 cups (800 mL) of water. For other spray
volumes, adjust proportionately.
Herbicide and Oil Concentrate - Add 2 teaspoons each
of herbicide and oil concentrate for each 2 pints per acre of
label rate.
Add components in the sequence indicated in the
Mixing Order using 2 teaspoons for each pound or
1 teaspoon for each pint of labeled rate per acre.
Cap jar, invert 10 cycles between component additions, let
stand for 15 minutes.
Evaluate - An ideal tank mix combination will be uniform.
The suitability of the oil concentrate is questionable if any of
the following are observed:
• Free oil at the surface - Film or globules
• Flocculation - Fine particles which may be suspended
in the liquid or found as a precipitated layer at the bottom
of the jar
• Clabbering -Thickening texture (coagulated) resembling
yogurt or a curd-like texture as with cottage cheese
Mixing Order
1. Water - Fill tank 1/2 to 2/3 full with clean water and start
agitation.
2. Agitation - Maintain agitation throughout mixing.
3. Inductor - If an inductor is used, rinse it thoroughly after
each component has been added.
4. Products in PVA 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-soluble additives (including NIS, and nitrogen
fertilizers such as AMS or UAN)
6. Water-dispersible products (such as dry flowables,
wettable powders, suspension concentrates, or
suspoemulsions)
7. Water-soluble products (such as Basagran)
8. Emulsifiable concentrates (such as COC or MSO oil
concentrate)

Application Restrictions
• DO NOT apply to weeds under stress such as lack of
moisture, herbicide injury, mechanical injury, or cold tem-
peratures, or unsatisfactory control may result.
• DO NOT apply to crops subjected to stress conditions
such as hail damage, flooding, drought, injury from other
herbicides, or widely fluctuating temperatures, or crop
injury may result.
• DO NOT apply to crops that show injury (leaf phytotoxici-
ty or plant stunting) produced by any other prior
herbicide applications because this injury may be
enhanced or prolonged.
• Rainfast period: Rainfall or overhead irrigation within
4 hours after application may reduce the effectiveness of
Basagran
® herbicide.
• DO NOT apply through any type of irrigation system.
Crop-specific Information
This section provides use directions for Basagran in spe-
cific crops. Read product information, mixing, application,
weeds controlled, and additive instructions in the preced-
ing sections of the label. Always read and follow all label
directions when using this product alone, or when in tank
mix combinations. The most restrictive labeling applies
when using tank mixes.
Alfalfa Grown for Seed
For use ONLY in Idaho, Montana, Nevada, Oregon,
Washington, and Wyoming.
Seed alfalfa is tolerant to postemergence applications of
Basagran, however some leaf speckling, leaf bleaching or
whitening, and temporary stunting may occur under certain
conditions. Applications made at or after flower bud forma-
tion may reduce seed yields.
Apply Basagran in the spring as a broadcast postemer-
gence application at rates up to 2 pints per acre to alfalfa
with at least 2 trifoliate leaves, but with no flower bud for-
mation. If needed for additional control of troublesome
weeds, make a second application 7 to 14 days later at the
same use rate.
The addition of oil concentrate (see Additives section for
details) to Basagran on seed alfalfa may result in slight leaf
burn or temporary stunting, but all new growth is normal.
The potential for leaf burn is increased when relative
humidity and temperature are high. A few oil concentrates
have exhibited excessive leaf burn. Refer to your supplier of
Basagran for information concerning successful local
experience before purchasing any oil concentrate.
Crop-specific Restrictions
• DO NOT apply Basagran if alfalfa shows injury (leaf phy-
totoxicity and/or plant stunting) produced by any other
prior herbicide applications because this injury may be
enhanced and/or prolonged.
• For use only in fields of alfalfa grown for seed production.
• DO NOT use on alfalfa produced for livestock feed.
• DO NOT use Basagran-treated alfalfa seed for
sprouting.
• DO NOT apply more than 4 pints (2.0 pounds of
bentazon ai) of Basagran per acre, per year.
• DO NOT apply more than a total of 2 pints (1.0 pound
of bentazon ai) of Basagran per acre per single
application.
• Maximum number of applications per year: DO NOT
make more than 2 applications per year.
• DO NOT make more than one application within a 7-day
period.
Special Crop Use Restrictions
The pesticide applicator, the producer of the crop, and the
seed conditioner must be aware that use of this product
according to this labeling is deemed a nonfeed/nonfood
use. If the applicator of this pesticide is not the producer,
the applicator should provide a copy of this labeling to the
producer of the crop. Producers of this crop who use this
product, or cause the product to be used on a field they
operate, should provide a copy of this pesticide label to the
seed conditioner.
This pesticide does not have an established pesticide
residue tolerance for alfalfa. Consequently, no portion of
this alfalfa seed crop, including but not limited to, forage or
stubble, green chop, hay, pellets, meal, whole seed,
cracked seed straw, or seed screenings, may be used or
distributed for human food or animal feed purposes.
Any alfalfa seed from a field treated with this product must
bear a specific tag or conspicuous container labeling, or if
shipped in bulk, on the shipment invoice or bill of lading,
with the following statement: “Not for human or animal
consumption”. All seed screenings from seed processing
shall be disposed of in such a manner that the screenings
cannot be distributed or used for human food or animal
feed purposes.
Beans, Dry and Succulent
Bean types tolerant to Basagran are adzuki, navy, pinto,
pink, great northern, kidney, red, white, cranberry, black
turtle soup, small lima, large lima, and snap beans.
Apply Basagran to beans after the first trifoliate leaf has
fully expanded. Even at the tolerant stages, yellowing,
bronzing, speckling or burning of leaves may occur under
certain conditions. This temporary injury is generally
outgrown without delaying podset or maturity or reducing
yield. Applying Basagran with an oil concentrate (COC or
MSO) may increase crop injury (i.e., increase leaf burn) and
may reduce yields, especially for snap beans.
State-specific Instructions for Georgia and
South Carolina. DO NOT apply Basagran as a solo
treatment to dry and succulent beans or severe crop injury
may occur. Basagran may be applied from 6 to 16 fluid 10
ounces per acre to dry and succulent beans only when
tank mixed with Raptor® herbicide or Pursuit®
herbicide. Refer to the Raptor and Pursuit labels for
additional use directions or restrictions.
Crop-specific Restrictions
• DO NOT apply Basagran® herbicide to beans before
the first trifoliate leaf is fully expanded because severe
crop injury may occur.

• Stinger® herbicide
Peas, Dry and Succulent
Pea types tolerant to Basagran are garden, English, and
southern peas.
Apply Basagran to peas after three pairs of leaves (or
4 nodes) are present. Even at the tolerant stages, yellow-
ing, bronzing, speckling, or burning of leaves may occur
under certain conditions. This temporary injury is generally
outgrown without delaying podset or maturity or reducing
yield.
In western irrigated areas, avoid applying Basagran during
prolonged periods (for 2 to 5 days) of cold weather (day
temperature below 75° F and night temperature below
55° F) because weed control may be nullified.
State-specific Instructions for Georgia and
South Carolina. DO NOT apply Basagran as a solo
treatment to dry and succulent peas or severe crop
damage may occur. Basagran may be applied from 6 to
16 fluid ounces per acre to dry and succulent peas only
when tank mixed with Raptor
® herbicide or Pursuit®
herbicide. Refer to the Raptor and Pursuit labels for
additional use directions or restrictions.
Crop-specific Restrictions
• DO NOT apply Basagran to dry peas within 30 days or
to succulent peas within 10 days of harvest.
• DO NOT apply Basagran to peas under stress from root
rot.
• DO NOT apply Basagran to garbanzo beans or to
lupines at any stage of growth, or severe crop injury may
occur.
• DO NOT apply Basagran when peas are in bloom.
• DO NOT add oil concentrate to Basagran for use on
peas, except for use in the Pacific Northwest (PNW).

Tank Mixtures
Basagran may be applied in a tank mix with one of the
following herbicides:
• Pursuit
• Raptor
• Reflex
® herbicide
• Thistrol® herbicide
• MCPA
The Basagran + Thistrol tank mix is for use in the north-
eastern states of Connecticut, Maine, Massachusetts,
New Hampshire, New Jersey, New York, Pennsylvania,
Rhode Island, Vermont, and in the mid-Atlantic states of
Delaware, Maryland, Virginia, and in the Pacific northwest-
ern states of Idaho, Oregon, and Washington. Apply this
tank mix after the 3-leaf stage (4-node stage) of peas, but
not later than 3 nodes before pea flowering.
NOTICE TO USER: Because of variability among pea cul-
tivars and in application techniques, neither the
manufacturers nor the sellers have determined whether or
not the tank mix of Basagran + Thistrol can be safely
used on all pea crops under all conditions. Therefore,
determine if the tank mix of Basagran + Thistrol can be
used safely before broad use.

Tank Mix Restrictions
• DO NOT use oil concentrate, other oil-based additives,
or any other spray additives or surfactants with these
tank mixes.
• DO NOT apply the tank mix to peas when temperatures
exceed 90º F.
• DO NOT apply the tank mix to peas after pea flower
buds appear.
• Other crops, in particular beans, cotton, grapes, toma-
toes, and ornamental plants, may be severely injured by
off-target spray drift of Thistrol.
12
Peanuts

period.
Tank Mixtures
Basagran may be applied in a tank mix with one of the
following herbicides:
• Cadre® herbicide
• Outlook® herbicide
• Poast® herbicide
• Pursuit® herbicide
• Cobra® herbicide
• ET® herbicide/defoliant
• Gramoxone® Inteon herbicide
• Ultra Blazer® herbicide
• 2,4-DB amine
Apply the Basagran + Gramoxone Inteon tank mix at
the ground crack stage of peanuts to control an early flush
of weeds. Apply a second application up to 28 days after
ground crack stage. Always add NIS at the recommended
rates to the Basagran + Gramoxone Inteon tank mix.
DO NOT use an oil concentrate or any other oil-based
additive with the Basagran + Gramoxone Inteon tank
mix.
Basagran may be tank mixed with foliar fungicides such
as Headline
® SC fungicide and Priaxor® fungicide.
Tank Mix Restrictions
• DO NOT include UAN solution or AMS with Basagran +
Ultra Blazer + Poast tank mix.
• DO NOT add oil concentrate, UAN, or any other
additives to Basagran + 2,4-DB tank mix.
• Use only amine formulations of 2,4-DB.
Rice
Apply Basagran early postemergence in rice, at the use
rates specified in and before weeds exceed the maximum
size listed in Table 3 and Table 4.
Alternate Flooding Culture
In Texas, Louisiana, Arkansas, and Mississippi, weed
growth stages generally correspond to rice that is tillering
(stooling) and occur before the permanent flood.
Basagran must be applied when there is no water on the
field and 24 hours or more before flooding. If Basagran
cannot be applied until after flooding, see directions under
Continuous Flooding Culture.
Continuous Flooding Culture
In states using continuous flooding culture, or when treat-
ing after the permanent flooding, treatment must be made
only when weeds are above the surface of the water.
Weeds submerged at the time of application will not be
adequately controlled. For early treatment, water may be
partly or completely drained to expose more weed growth
to spray applications of Basagran. DO NOT raise water
level for at least 24 hours after application or unsatisfactory
control may result. DO NOT use ground equipment to
apply to flooded fields because splashing will wash
Basagran off weed leaf surfaces and ineffective control
may result.
Crop-specific Restrictions
• Rice straw may be fed to livestock.
• DO NOT use Basagran on rice fields in which the com-
mercial cultivation of catfish or crayfish is practiced.
• DO NOT use water containing Basagran residues from
rice cultivation to irrigate crops used for food or feed
unless Basagran is registered for use on these crops.
• DO NOT apply more than 4 pints (2.0 pounds of
bentazon ai) of Basagran per acre per year whether one
or two rice crops (including ratoon) are grown that year
(season).
• DO NOT apply more than a total of 2 pints (1.0 pound
of bentazon ai) of Basagran per acre per single
application.
• Maximum number of applications per year: DO NOT
make more than 2 applications per year.
• DO NOT make more than one application within a 5-day
period.
• DO NOT release paddy water from Basagran treated
fields for at least 4 days after last application to flooded
paddies.

• DO NOT apply to sorghum that is heading or blooming.
• DO NOT graze treated sorghum fields for at least
12 days after the last treatment with Basagran.
Tank Mixtures
Basagran may be tank mixed with one or more of, but not
limited to, the following herbicide products:
• Clarity® herbicide
• Facet® L herbicide
• Outlook® herbicide
• atrazine
Soybeans
Apply Basagran postemergence to soybean, as they are
tolerant to Basagran at all stages of growth. Slight leaf
speckling and leaf bronzing may occur under certain condi-
tions, but soybeans generally outgrow these conditions
within 10 days.
Crop-specific Restrictions
• DO NOT graze or cut treated soybean fields for forage or
hay for at least 30 days after the last treatment of
Basagran.
• DO NOT apply more than 4 pints (2.0 pounds of
bentazon ai) of Basagran per acre, per year.
• DO NOT apply more than a total of 3 pints (1.5 pounds
of bentazon ai) of Basagran per acre per single
application.
• Maximum number of applications per year: DO NOT
make more than 2 applications per year.
• DO NOT make more than one application within a 5-day

Tank Mixtures
Basagran® herbicide may be tank mixed or applied
sequentially with one or more of, but not limited to, the fol-
lowing herbicide products:
• Outlook
® herbicide
• Poast® herbicide
• Pursuit® herbicide
• Raptor® herbicide
• Scepter® herbicide
• Cobra® herbicide
• Flexstar® herbicide
• Reflex® herbicide
• Resource® herbicide
• Ultra Blazer® herbicide
• 2,4-DB amine
• glyphosate (e.g. Roundup
® herbicide)
Basagran may be tank mixed with foliar fungicides and/or
foliar insecticides (except malathion and Sevin® herbicide)
if the application timings properly coincide.
Tank Mix Restrictions
Basagran + Ultra Blazer + Poast. Oil concentrate must
be used with the Basagran + Ultra Blazer + Poast tank
mix in place of a spray surfactant.
Basagran + 2,4-DB amine. Use only amine formulations
of 2,4-DB. Use no other adjuvant except UAN at 2 to
4 pints per acre with this tank mix. DO NOT apply more
than 1 application of this tank mix per season. The use of
this tank mix will cause soybean foliage injury (such as
burning, bronzing, or crinkling) and may reduce yields.
DO NOT use this tank mix on soybeans that show symp-
toms of disease such as Phytophthora root rot.
The tank mixing of an insecticide with Basagran may
increase the potential for crop injury.
Nonbearing Food Crops
Basagran may be used for selective postemergence weed
control in the following nonbearing food crops: almonds,
apples, apricots, avocados, blackberries*, blueberries,
cherries, crabapples, dates, figs, grapes, grapefruit,
lemons, limes, macadamias, nectarines, olives, oranges,
peaches, pears, pecans, pistachios, plums, pomegranates,
prunes, raspberries*, tangelos, tangerines, walnuts.
(* Apply Basagran at or before planting only)
Apply Basagran at 1.5 to 2 pints per acre as a postemer-
gence directed spray away from the foliage of desired
plants. DO NOT allow spray to contact green stems, bark,
or foliage. A directed spray application should reduce the
potential for leaf injury. However, some leaf speckling and
leaf bronzing may occur under certain conditions. If need-
ed, use a spray shield or wrap or cover the plants when
spraying around very young trees or vines.
Crop-specific Restrictions
• DO NOT apply to nonbearing foods using aircraft or any
aerial equipment that results in a broadcast spray
application.
• DO NOT graze animals in treated orchards or fields.
• DO NOT use hay from treated areas for animal feed or
bedding.
• DO NOT apply Basagran to nonbearing food crops
within one year of harvest.
• DO NOT apply more than 4 pints (2.0 pounds of
bentazon ai) of Basagran per acre, per year.
• DO NOT apply more than a total of 2 pints (1.0 pound
of bentazon ai) of Basagran per acre per single
application.
• Maximum number of applications per year: DO NOT
make more than 2 applications per year.
• DO NOT make more than one application within a 5-day
period.
