Precautionary Statements
Hazards to Humans and Domestic Animals
CAUTION. Harmful if absorbed through skin. Harmful if
swallowed. Causes moderate eye irritation. Avoid contact
with skin, eyes, or clothing.
Personal Protective Equipment (PPE)
Applicators and other handlers must wear:
• Protective eyewear such as face shield, goggles, or 
safety glasses
• Long-sleeved shirt and long pants
• Chemical-resistant gloves
• Shoes plus socks
Follow the manufacturer’s 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. Discard clothing and other
absorbent materials that have been drenched or heavily
contaminated with this product’s concentrate. DO NOT
reuse them.
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.
IMPORTANT:When reduced PPE is worn because a
closed system is being used, handlers must be provided all
PPE specified above for applicators and other handlers
and have such PPE immediately available for use in an
emergency, such as a spill or equipment breakdown.
Environmental Hazards
For terrestrial uses, DO NOT apply directly to water, areas
where surface water is present, or intertidal areas below
the mean high water mark. DO NOT contaminate water
when disposing of equipment washwater or rinsate.
Groundwater Advisory. This product has properties and
characteristics associated with chemicals detected in
groundwater. This chemical may leach into groundwater if
used in areas where soils are permeable, particularly where
the water table is shallow.
Surface Water Advisory. This product may impact sur-
face water due to runoff of rainwater. This is especially true
for poorly draining soils and soils with shallow groundwater.
This product is classified as having high potential for reach-
ing surface water via runoff for several weeks after
application. A level, well-maintained buffer strip between
areas to which this product is applied and surface water
features such as ponds, streams, and springs will reduce
the potential loading of this chemical from runoff water and
sediment. Runoff of this product will be reduced by avoid-
ing application when rainfall is forecast to occur within
48 hours.
USER SAFETY RECOMMENDATIONS
Users should:
• Wash hands thoroughly with soap and water after han-
dling and 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.

Proper Handling Instructions. This product may not be
mixed or loaded within 50 feet of wells (including aban-
doned wells and drainage wells), sinkholes, perennial or
intermittent streams and rivers, and natural or impounded
lakes and reservoirs. This setback does not apply to prop-
erly capped or plugged abandoned wells and does not
apply to impervious pad or properly diked mixing/loading
areas.
Operations that involve mixing, loading, rinsing, or washing
of this product into or from pesticide handling or applica-
tion equipment or containers within 50 feet of any well are
prohibited unless conducted on an impervious pad con-
structed to withstand the weight of the heaviest load that
may be positioned on or moved across the pad. Such a
pad must be designed and maintained to contain any
product spills or equipment leaks, container or equipment
rinse or washwater, and rainwater 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 110% 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 capacity of 100% 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 specific minimum
containment capacity DOES NOT apply to vehicles when
delivering pesticide shipments to the mixing/loading site.
States may have in effect additional requirements regarding
wellhead setbacks and operational containment.
This product must be used in a manner which will prevent
back-siphoning in wells, spills, or improper disposal of
excess pesticide spray mixture.
Endangered Species Protection
Requirements
This product may have effects on federally listed threatened
or endangered plant species or their critical habitat. When
using this product, you must follow the measures con-
tained in the Endangered Species Protection Bulletin for
the county or parish in which you are applying the pesti-
cide. To determine whether your county or parish has a
Bulletin, and to obtain that Bulletin, consult
http://www.epa.gov/espp/, or call 1-800-447-3813 no

Product Information
Optill® herbicide provides both contact burndown and
residual preemergence broadleaf and grass weed control
(refer to Table 1 and Table 2 for lists of weeds controlled
dependent on application rate). It can be used in
Clearfield
® corn and specified legume vegetable crops
including: chickpea (garbanzo bean), dry field peas,
English peas, and soybean. Refer to Crop-specific
Information section for use directions.
Make burndown application of Optill when weeds are
small and actively growing. An adjuvant is required with
Optill for optimum burndown activity (refer to Additives
section for details). Burndown activity may be slowed or
reduced under cloudy and/or foggy or cooler weather con-
ditions, or when weeds are growing under drought or other
stress conditions. When targeting dense weed populations
and/or larger broadleaf weeds, use higher spray volumes.
Angling nozzles forward (to 45 degrees) may improve pen-
etration of denser weed canopies.
Residual preemergence application of Optill must be acti-
vated by at least 1/2 inch of rainfall or sprinkler irrigation
before weed seedling emergence. When Optill is not acti-
vated, a labeled postemergence herbicide or cultivation
may be needed to control weed escapes.
STORAGE AND DISPOSAL
DO NOT contaminate water, food, or feed by storage or
disposal. Open dumping is prohibited.
Pesticide Storage
DO NOT use or store near heat or open flame. Store in
original container in a well-ventilated area separately from
fertilizer, feed, or foodstuffs and away from other pesti-
cides. Avoid cross-contamination with other pesticides.
Groundwater contamination may be reduced by diking
and flooring of permanent liquid bulk storage sites with an
impermeable material.
Pesticide Disposal
Wastes resulting from this product may be disposed of
on-site or at an approved waste disposal facility. Improper
disposal of excess pesticide, spray mix, or rinsate is a vio-
lation of federal law. If these wastes cannot be disposed
of according to label instructions, contact the state
 agency responsible for pesticide regulation or the
Hazardous Waste representative at the nearest EPA
Regional Office for guidance.
Container Handling
Nonrefillable Container. DO NOT reuse or refill this
container. Triple rinse or pressure rinse container (or
equivalent) promptly after emptying; then offer for recy-
cling, if available, or reconditioning, if appropriate, or
puncture and dispose of in a sanitary landfill, or by inciner-
ation, or by other procedures approved by state and local
authorities.
Triple rinse containers small enough to shake
(capacity
≤50 pounds) as follows: Empty the remain-
ing contents into application equipment or a mix tank. Fill
the container 1/4 full with water and recap. Shake for
10 seconds. Pour rinsate into application equipment or a
mix tank, or store rinsate for later use or disposal. Drain
for 10 seconds after the flow begins to drip. Repeat this
procedure two more times.
Pressure rinse as follows: Empty the remaining
 contents into application equipment or mix tank. Hold
 container upside down over application equipment or mix
tank, or collect rinsate for later use or disposal. Insert
pressure rinsing nozzle in the side of the container and
rinse at about 40 PSI for at least 30 seconds. Drain for
10 seconds after the flow begins to drip.

Mode of Action
Optill is a potent inhibitor of both protoporphyrinogen-
oxidase, belonging to herbicide mode-of-action Group 14
(WSSA)/Group E (HRAC), and acetohydroxyacid synthase,
belonging to herbicide mode-of-action Group 2
(WSSA)/Group B (HRAC). Optill is rapidly absorbed by
roots and foliage. Plant death is the result of membrane
damage and inhibition of the production of branched chain
amino acids. Under active growing conditions, susceptible
emerged weeds usually develop chlorotic and necrotic
injury symptoms within hours and die within a few days.
Susceptible emerging weed seedlings usually die as they
reach the soil surface or shortly after emergence.

While weed resistance to protoporphyrinogen-oxidase
inhibiting herbicide is relatively infrequent, populations of
resistant biotypes to protoporphyrinogen-oxidase or
 acetohydroxyacid-synthase inhibiting herbicides are known
to exist. Resistance management practices include:
1. Following labeled application rate and weed
growth-stage 
2. Avoiding repeated applications of herbicides with the
same mode of action
3. Using tank mixes and sequential applications with other
effective herbicides possessing different modes of action
4. Using crop rotation so that crop competition, tillage, or
herbicides with alternative modes of action can be used
to control weed escapes
Crop Tolerance
Crops are tolerant to Optill when applied according to
label directions as a preplant to pre emergence treatment
and under normal environmental conditions. Crop injury
may occur under stressful growing conditions (e.g. seedling
disease, extreme hot or cold weather, excessive moisture,
high soil pH, high soil salt concentration, or drought).
Severe crop injury will result if Optill is applied
 postemergence (over the top) to any crop.

Application Instructions
Apply Optill® herbicide before crop emergence only.
Application Methods and Equipment
Optill may be applied by ground or air. Thorough spray
coverage is required for optimum weed control and can be
improved with proper adjuvant, nozzle and spray volume
selection.
Use and configure application equipment to provide an
adequate spray volume, an accurate and uniform distribu-
tion of spray droplets over the treated area, and to avoid
spray drift to nontarget areas. Adjust equipment to main-
tain continuous agitation during spraying with good
mechanical or bypass agitation. Avoid overlaps that
increase rates above the use rates specified in this label.
Optill may only be applied using water as the spray carrier.
Aerial Application Requirements
Water Volume. Use 3 or more gallons of water per acre.
Applicators must follow these requirements to reduce the
potential of spray drift to nontarget areas from aerial
 application: 
1. The distance of the outermost nozzles on the boom
must not exceed 3/4 the length of the fixed wingspan or
90% of rotor blade diameter.
2. Use low-drift nozzles such as straight-stream nozzles
(D-8 or larger). DO NOT use nozzles producing a mist
droplet spray.
3. Nozzles must always point backward parallel with the
airstream and never be pointed downward more than
45 degrees.
4. Without compromising aircraft safety, application should
be made at a height of 10 feet or less above the crop
canopy or tallest plants.
5. DO NOT apply during periods of temperature inversion
or stable atmospheric conditions.
6. Avoid potential adverse effects to nontarget areas by
maintaining a 26-feet buffer between the point of direct
application and the closest downwind edge of sensi-
tive terrestrial habitats (such as grasslands, forested
areas, shelter belts, woodlots, hedgerows, riparian
areas, and shrub lands).
Ground Application Requirements
Water Volume. Use 5 or more gallons of water per treated
acre for weed control application. Thorough spray cover-
age is required for control of emerged broadleaf weeds.
High populations and/or variations in size can prevent thor-
ough spray coverage. Controlling fall-germinated weeds in
the spring (e.g. horseweed/marestail) will also require thor-
ough spray coverage. Use higher spray volumes (e.g. 15 to
20 gallons of water per acre) in these situations to increase
spray coverage and optimize burndown activity.
Applicators must follow these requirements to reduce the
potential of spray drift to nontarget areas from ground
applications: 
1. Apply this product using nozzles which deliver medium-
to-coarse spray droplets as defined by ASAE
standard S-572 and as shown in nozzle manufacturer’s
catalogs. Flat-fan nozzles are recommended for burn-
down applications while flood-jet type nozzles are
recommended for residual soil surface application.
Nozzles that deliver coarse spray droplets may be used
to reduce spray drift provided spray volume per
acre (GPA) is increased to maintain coverage of target
(i.e. weeds or soil surface). DO NOT use nozzles that
produce fine (e.g. cone) spray droplets.
2. Apply this product only when the potential for drift to
adjacent nontarget areas is minimal (e.g. when the wind
is 10 MPH or less and is blowing away from sensitive
areas). DO NOT apply during periods of temperature
inversion or stable atmospheric conditions.
3. Avoid potential adverse effects to nontarget areas by
maintaining a 13-feet buffer between the application
area and the closest downwind edge of sensitive ter-
restrial habitats (such as grasslands, forested areas,
shelter belts, woodlots, hedgerows, riparian areas, and
shrub lands).
Cleaning Spray Equipment
Clean application equipment thoroughly using a strong
detergent or commercial sprayer cleaner according to the
manufacturer’s directions, followed by triple rinsing the
equipment before and after applying this product.
Spray Drift Management
It is the responsibility of the applicator to avoid spray drift at
the application site, especially onto nontarget areas. The
interaction of many equipment-related and weather-related
factors determines the potential for spray drift. The applica-
tor and the grower are responsible for considering all these
factors when making decisions.
The applicator should be familiar with and take into
account the information covered in the following spray drift
reduction advisory information.
Controlling Droplet Size. The most effective way to
reduce drift potential is to apply the largest droplets that
provide sufficient coverage and control.
Volume. Use high flow rate nozzles to apply the highest
practical spray volume. Nozzles with higher rated flows
produce larger droplets.
Pressure. DO NOT exceed the nozzle manufacturer’s rec-
ommended pressures. For many nozzle types, lower
pressure produces larger droplets. When higher flow rates
are needed, use higher flow rate nozzles instead of increas-
ing pressure.
Number of Nozzles. Use the minimum number of nozzles
that provide uniform coverage.
Nozzle Type. Use a nozzle type that is designed for the
intended application. With most nozzle types, narrower
spray angles produce larger droplets.
Swath Adjustment. When applications are made with a
crosswind, the swath will be displaced downwind.

11
Therefore, on the upwind and downwind edges of the field,
the applicator must compensate for this displacement by
adjusting the path of the application equipment (e.g. air-
craft, 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 to
10 mph. However, many factors, including droplet size and
equipment type, determine drift potential at any given
speed. If applying at wind speeds less than 3 mph, the
applicator must determine if: 
1. Conditions of temperature inversion exist, or 
2. Stable atmospheric conditions exist at or below nozzle
height.
DO NOT make applications into areas of temperature
inversions or stable atmospheric conditions.
NOTE: Local terrain can influence wind patterns. Every
applicator should be familiar with local wind patterns and
how they affect spray drift.
Wind Erosion. Avoid treating 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.
Additives
For optimum burndown activity with Optill® herbicide, an
adjuvant system must be used that includes the following:
1 MSO-based adjuvant MUST contain at least 60% methylated seed oil.
Poor performance may occur with adjuvants containing less than 60%
methylated seed oil.
2 DO NOT use less than 1 pint/A of MSO with low-volume (< 12.5 gallons
per acre) aerial or ground applications.
Use of AMS fertilizer is highly recommended when mixing
Optill with glyphosate-based herbicides.
DO NOT use nonionic surfactant (NIS) as a substitute for
MSO or poor performance on broadleaf weeds will occur.
When an adjuvant is to be used with this product, BASF
recommends the use of a Chemical Producers and
Distributors Association (CPDA) certified adjuvant.
Tank Mixing Information
Optill may be tank mixed with one or more registered
 herbicide products according to the specific tank mixing
instructions in this label and respective product labels. It is
the pesticide user’s responsibility to ensure that all prod-
ucts in the listed mixtures are registered for the intended
use. Users must follow the most restrictive directions for
use and precautionary statements of each product in the
tank mixture. Refer to Crop-specific Information section
for details.
Tank mixes with contact herbicides (e.g. carfentrazone,
paraquat) may reduce the burndown activity of Optill.
Compatibility Test for Mix Components
Before mixing components, always perform a compatibility
jar test.
1. 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.
2. Add components in the sequence indicated in Mixing
Order using 2 teaspoons for each pound or 1 teaspoon
for each pint of label rate per acre.
3. Always cap the jar and invert 10 cycles between compo-
nent additions.
4. When the components have all been added to the jar, let
the solution stand for 15 minutes.
5. Evaluate the solution for uniformity and stability. The
spray solution should not have free oil on the surface,
fine particles that precipitate to the bottom, or thick
(clabbered) texture. If the spray solution is not
 compatible, repeat the compatibility test with the addi-
tion of a suitable compatibility agent. If the solution is
then compatible, use the compatibility agent as directed
on its label. If the solution is still incompatible, DO NOT
mix the ingredients in the same tank.
Mixing Order
Maintain constant agitation throughout mixing and applica-
tion until spraying is completed.
1. Water - Fill tank 1/2 to 3/4 full with clean water and start
agitation.
2. Inductor - If an inductor is used, rinse it thoroughly after
each component has been added.
3. 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.
4. Water-soluble additives (including dry and liquid fertil-
izers such as AMS or UAN)
5. Water-dispersible products (such as dry flowables,
wettable powders, suspension concentrates, or 
 suspo-emulsions)
6. Water-soluble products
7. Emulsifiable concentrates (including MSO adjuvants)
8. Remaining quantity of water
If the spray mixture is allowed to settle for any period of
time, thorough agitation is essential to resuspend the mix-
ture before spraying is resumed. Continue agitation while
spraying.

Use Restrictions
• Maximum seasonal use rate - Refer to the Crop -
specific Information section for maximum cropping
seasonal application use rates for each crop and use pat-
tern. A cropping season is defined as the period following
harvest of the preceding crop through the harvest of the
planned or current crop.
• DO NOT apply Optill
® herbicide after crop emergence.
• DO NOT contaminate irrigation ditches or water used for
domestic purposes.
• DO NOT apply Optill through any type of irrigation sys-
tem (e.g. chemigation).
• Optill is not for sale, distribution, or use in Nassau
and Suffolk counties in New York State.
Use Precautions
• Optill will cause severe crop injury if applied after crop
emergence. 
• Full rate application of products containing chlorimuron
ethyl, chloransulam-methyl, flumetsulam, imazaquin, or
imazethapyr in the same year as Optill may increase the
risk of injury to sensitive follow crops. Consult the respec-
tive labels of these products for recommended uses of
these products in combinations.
• Only rotational crops harvested at maturity may be used
for feed or food.
• When organophosphate or carbamate insecticides are
tank mixed with Optill, temporary injury may result to the
treated crops.
• Rainfastness - Optill is rainfast 1 hour after application.
Burndown activity may be reduced if rain or irrigation
occurs within 1 hour of application.
Rotational Crop Restrictions, Crop Rotation,
and Emergency Replanting Intervals
Use Table 3 and its exceptions in the paragraphs following
the table to determine the proper interval between Optill
application and rotational crop planting to determine the
acceptable planting interval for rotational crops as well as
replanting after crop failure (because of environmental fac-
tors such as drought, frost or hail, etc.). Determine the
rotational crop interval for tank mix* products and use the
most restrictive interval of all products applied.
* Refer to Tank Mixing Information section for further instructions.
Table 3. Rotational Crop Planting and Emergency
Replanting Intervals after application of Optill at
2.0 ozs/A
a The planting interval for these crops and rates is further defined in the
respective Crop-specific Information section of this label. Use the
longer interval within listed ranges for indicated crops grown on coarse-
textured soils with organic matter less than 2.0%.
b Use the longest interval for rye grown in North Dakota and Minnesota
north of Highway #210.
c Following 40 months after an Optill application and before planting any
crop not listed elsewhere in the Rotational Crop Restrictions, Crop
Rotation, and Emergency Replanting Intervals, a successful field
bioassay must be completed. The field bioassay consists of a test strip
of the intended rotational crop planted across the previously treated field
and grown to maturity. The test strip should include low areas and knolls
and include variations in soil such as type and pH. If no crop injury is evi-
dent in the test strip, the intended rotational crop may be planted the
following year. Sugar beet production can be reduced when grown in
soil conditions with a pH less than 6.5. If the field is limed to adjust pH
before planting rotational crops not listed in Rotational Crop
Restrictions, Crop Rotation, and Emergency Replanting Intervals,
apply the lime at least 12 months before planting the rotational crop.
Use of Optill in accordance with label directions is expect-
ed to result in normal growth of rotational crops in most
situations. However, various environmental and agronomic
factors make it impossible to eliminate all risks associated

Crop-specific Information
This section provides use directions for Optill in specific
crops. Read product information, mixing, application,
weeds controlled and adjuvant instructions in preceding
sections of the label. It is the pesticide user’s responsibility
to ensure that all products in the listed mixtures are regis-
tered for the intended use. Users must follow the most
restrictive directions for use and precautionary statements
of each product in the tank mixture.
Depending on specific crop application directions, Optill
may be applied for burndown control of emerged weeds
and/or residual control of germinating weeds (refer to
Table 1 and Table 2 for lists of weeds controlled depen-
dent on application rate) before planting (preplant/preseed)
or after planting but before crop emergence. Depending on
the time between Optill application and planting, a fol-
lowup in-crop herbicide application may be needed for
complete weed control throughout the growing season.
Thorough spray coverage is required for control of
emerged broadleaf weeds. High populations and/or
 variations in size can prevent adequate spray coverage.
Controlling fall-germinated weeds in the spring 
(e.g. horseweed/marestail) also requires thorough spray
coverage. Use higher spray volumes (e.g. 15 to 20 gallons
of water per acre) in these situations to increase spray cov-
erage and optimize burndown activity. 
Clearfield® Corn
Use Optill in Clearfield corn production only. Use in 
non-Clearfield corn or after corn emergence will result in
crop injury.
Application Method, Rate, and Timing
Apply Optill at 2.0 ozs/A in a single application as a pre-
plant burndown, preplant incorporated, or preemergence
treatment in Clearfield corn (refer to Table 1 for list of
weeds controlled).
Crop-specific Restrictions
• Use only in Clearfield corn.
• Not for use in Clearfield corn in California.
• DO NOT apply Optill in North Dakota and Minnesota
(north of Highway #210) in Clearfield corn.

The Directions For Use of this product reflect the
opinion of experts based on field use and tests. The
directions are believed to be reliable and must be
followed carefully. However, it is impossible to eliminate all
risks inherently associated with the use of this product.
