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 apply when weather conditions favor drift from areas treated. Do not
contaminate water when disposing of equipment washwaters or rinsate.
Groundwater Advisory: Metribuzin is a chemical which can travel (seep or leach) through soil and can contaminate
groundwater which may be used as drinking water. Metribuzin has been found in groundwater as a result of
agricultural use. Users are advised not to apply metribuzin where the water table (groundwater) is close to the
surface, and where the soils are very permeable, i.e., well-drained soils such as loamy sands. Your local agricultural
agencies can provide further information on the type of soil in your area and the location of groundwater.
PHYSICAL AND CHEMICAL HAZARDS
Do not allow to come in contact with an oxidizing agent, as a hazardous chemical reaction could occur.
RESISTANCE MANAGEMENT
To minimize the occurrence of resistant weed biotypes, observe the following general weed management
practices:
x Scout application site before and after herbicide applications.
x Start with a clean application site, suing either a burndown herbicide application or tillage.
x Control weeds early when they are relatively small.
x Add other herbicides (e.g. a selective and/or a residual herbicide) and cultural practices (e.g., tillage or crop
rotation) where appropriate.
x Utilize the specified label rate for the most difficult to control weed in your field. Avoid tank mixtures with
other herbicides that reduce this product’s efficacy (through antagonism), or tank mixture directions that
encourage application rates of this product below the label directions.
x Control weed escapes and prevent weeds from setting seeds.
x Clean equipment before moving from field to field to minimize the spread of weed seed or plant parts.
x Report any incidence of repeated non-performance of this product on a particular weed to your Atticus, LLC
representative, local retailer, or county extension agent.

CHEMIGATION
This product may be used for application through sprinkler irrigation equipment to potatoes, soybeans, tomatoes,
a n d a s p a r a g u s a s d i r e c t e d o n t h i s l a b e l . R e f e r t o t h e c rop sections of this label for rates, weeds controlled or
suppressed, restrictions and precautions.
Apply this product only through sprinkler (including center pivot, lateral move, or solid set) irrigation systems. Do
not apply this product through any other type of irrigation system.
Crop injury, lack of effectiveness, or illegal pesticide residu es in the crop can result from nonuniform distribution of
treated water.
Calibration: (Center Pivot and Self-Propelled Lateral Move System): Sprinkler irrigation systems must be accurately
calibrated for application of this product. Greater accuracy in calibration (and distribution) will be achieved by
5
injecting a larger volume of a more dilute mixture of product and water per hour. Follow the steps below to calibrate
center pivot and lateral move systems:
1. Determine the number of minutes required to make 1 complete revolution while applying ¼ to ¾ inch of
water per acre.
2. With the system at operating pressure determine the exact number of minutes required to inject 1.0 gallon
of water.
3. Divide the time required for 1 revolution (step 1) by the time required to inject 1.0 gallon (step 2). This
gives total gallons of product-water mixture to be added to nurse tank.
4. Add required amount of water to nurse tank and start the agitation system. Then add this product at the
appropriate rate (see Broadcast Applications) to the nurse tank.
Example: If 20 hours (1200 minutes) were required for 1 revoluti on and if 2 minutes were required to inject 1.0
gallon, then a total of 600 gallons of product-water mi xture are required (1200/2=600); to treat 135 acres at 0.6
pound per acre, 90.5 pounds of this product are required.
If you have questions about calibration, contact State Extension Service Specialists, equipment manufacturer’s or
other experts.
Do not connect in irrigation system (including greenhouse systems) used for pesticide application to a public water
system unless the pesticide label-prescribed safety devices for public water systems are in place.
A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of
the responsible person, shall shut the system down and make necessary adjustments should the need arise.
The system must contain a functional check valve, vacuum relief valve, and low pressure drain appropriately located
on the irrigation pipeline to prevent water source contamination from backflow.
The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow
of fluid back toward the injection pump.
The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on
the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn
from the supply tank when the irrigation system is either automatically or manually shut down.
The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when
the water pump motor stops.
The irrigation line or water pump must include a function al pressure switch which will stop the water pump motor
when the water pressure decreases to the point where pesticide distribution is adversely affected.
Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump)
effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted
with a system interlock.
Do not apply when wind speed favors drift beyond the area intended for treatment.
Maintain continuous agitation in the injection nurse tanks during the herbicide application, sufficient to keep
herbicide in suspension.
Apply specified dosage in ¼ to ¾ inch of water (1/4 to 1/ 2 inch of water on sandy soils) per acre as a continuous
injection in center pivot and lateral move systems or in the last 15 to 30 minutes of set in permanent solid set
sprinkler systems. Application of more than the quantity of irrigation water listed on this label may result in
decreased product performance by removing the chemical from the zone of effectiveness. Where sprinkler
distribution patterns do not overlap sufficiently unacceptable weed control may result. Where sprinkler distribution
patterns overlap excessively, crop injury may result. Allow sufficient time for pesticide to be flushed through all lines
6
and all nozzles before turning off irrigation water. To ensure that lines are flushed and free of remaining pesticide,
an indicator dye may be injected into the lines to mark the end of the application period.
Use a minimum of 1 part water to 1 part herbicide for injection. The use of a larger volume of water will ensure
greater accuracy and more uniform distribution.
Aerial Drift Reduction Advisory Information
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-
and weather-related factors determine the potential for spra y drift. The applicator and the grower are responsible
for considering all these factors when making decisions.
The following drift management requirements must be followed to avoid off-target drift movement from aerial
applications to agricultural field crops. These requirements do not apply to forestry applications, public health uses
or to applications using dry formulations.
1. The distance of the outer most nozzles on the boom must not exceed ¾ the length of the wingspan or rotor.
2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more
than 45 degrees.
3. Where states have more stringent regulations, they must be observed.
4. The applicator should be familiar with and take into account the information covered in the Aerial Drift
Reduction Advisory Information.
Information on Droplet Size: The most effective way to reduce drift pote ntial is to apply large droplets. The best
drift management strategy is to apply the largest droplets that provide sufficient coverage and control. Applying
larger droplets reduces drift potential, but will not pr event drift if applications are made improperly, or under
unfavorable environmental conditions (see Wind, Temperature and Humidity and Temperature Inversions).
Controlling Droplet Size
x Volume – Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated
flows produce larger droplets.
x Pressure – Do not exceed the nozzle manufacturer’s specified 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.
x Number of Nozzles – Use the minimum number of nozzles that provide uniform coverage.
x Nozzle Orientation – Orienting nozzles so that the spray is released parallel to the airstream produces larger
droplets than other orientations and is the recommended practice. Significant deflection from horizontal
will reduce droplet size and increase drift potential.
x Nozzle Type – Use a nozzle type that is designed for the intended application. With most nozzle types,
narrower spray angles produce larger droplets. Cons ider using low-drift nozzles. Solid stream nozzles
oriented straight back product the largest droplets and the lowest drift.
Boom Length: For some use patterns, reducing the effective boom length to less than ¾ of the wingspan or rotor
length may further reduce drift without reducing swath width.
Application Height: Applications should not be made at a height greater than 10 feet above the top of the largest
plants unless a greater height is required for aircraft safety. Making applications at the lowest height that is safe
reduces exposure of droplets to evaporation and wind.
Swath Adjustment: When applications are made with a crosswind, the swath will be displaced downwind.
Therefore, on the up and downwind edges of the field, the applicator must compensate for this displacement by
adjusting the path of the aircraft upwind. Swath adjustment distance should increase with increasing drift potential
(higher wind, smaller drops, etc.).
7
Wind: Drift potential is lowest between wind speeds of 2 to 10 mph. However, many factors, including droplet size
and equipment type determine drift potential at any given speed. Application should be avoided below 2 mph due
to variable wind directions and high inversion potential. Note: Local terrain can influence wind pattern. Every
applicator should be familiar with local wind patterns and how they affect spray drift.
Temperature and Humidity: When making applications in low relative humidity, set up equipment to produce larger
droplets to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry.
Temperature Inversions: Applications should not occur during a temperature inversion because drift potential is
high. Temperature inversions restrict vertical air mixing, which causes small, suspended droplets to remain in a
concentrated cloud. This cloud can move in unpredictable directions due to the light variable winds common during
inversions. Temperature inversions are characterized by increasing temperatures with altitude and are common on
nights with limited cloud cover and light to no wind. They begin to form as the sun sets and often continue into the
morning. Their presence can be indicated by ground fog; however, if fog is not present, inversions can also be
identified by the movement of smoke from a ground source or an aircraft smoke generator. Smoke that layers and
moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves
upward and rapidly dissipates indicates good vertical air mixing.
Sensitive Areas: Only apply this product when the potential for dr ift to adjacent sensitive areas (e.g., residential
areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal (e.g., when
wind is blowing away from the sensitive areas).
Application of This Product with Herbicide Spray Equipment
Use a standard low-pressure (20 to 40 psi) herbicide boom sprayer equipped with suitable nozzles and screens no
finer than 50-mesh in nozzle and in-line strainers. Agitate thoroughly before and during application with bypass
agitation. Low pressure and high volume hand wand equipment is prohibited.
Ground Application: Apply the proper rate of this product in a minimum of 10.0 to 40.0 gallons of spray mixture per
acre broadcast.
Banded Application: Use proportionately less of this product per acre in a band versus a broadcast application. For
band application use 0.25 to 1.0 gallon of spray mix per inch of band width regardless of row spacing.
Examples: (1) To treat a 15-inch band on rows 30 inches apart, us e 1/2 of the broadcast rate of this product. (2) To
treat a 14-inch band on rows 42 inches apart, use 1/3 of the broadcast rate of this product.
Aerial Application: Where permitted, apply specified rate in a minimum of 2.0 to 10.0 gallons of spray mixture per
acre. Do not apply aerially when wind speed is greater than 10 mph.
Restriction: Do not apply aerially when this product is tank mixed with alachlor.
For All Applications of A342.01: Sprayer must be accurately calibrated before applying this product. Check sprayer
during application to be sure it is working properly and delivering a uniform spray pattern. As the volume of spray
mixture decreases per acre, the importance of accurate calibration and uniform application increases. Avoid over
application, misapplication, and boom and spray swath over lapping that will increase spray dosage. (Crop injury
may occur as a result.) Avoid spray skips and gaps which allow weeds to grow in untreated soil. Do not apply when
weather conditions favor spray drift and/or when sensitive or cool season crops, such as cole crops, onions, peas, or
strawberries are present in adjacent fields or in areas where wheat is growing in coarse textured soils.
Sprayer Cleanup: Spray equipment must be thoroughly cleaned to remove remaining traces of herbicide that might
injure other crops to be sprayed. Drain any remaining spray solution of this product from the spray tank and dispose
of according to label disposal instructions. Rinse the spray tank and refill with water, adding a heavy-duty detergent
at the rate of 1 cup per 20.0 gallons of water. Recycle this mixture through the equipment for 5 minutes and spray
out. Repeat this procedure twice. Fill the spray tank with clean water, recycle for 5 minutes, and spray out. Clean
8
pump and nozzle screens thoroughly. Wash away any spray mixture from the outside of spray tank, nozzles or spray
rig. All rinse water must be disposed of in compliance with local, state, and Federal guidelines.
Application of A342.01 in Fluid Fertilizers
This product may be applied in fluid fertilizer solutions to alfalfa and soybeans by following the appropriate mixing
procedures and compatibility check. When using tank mix combinations, be sure all components are compatible.
Make compatibility checks of this product and tank mix co mbinations which include this product for each batch of
fluid fertilizer because of the variability of these fertilizers.
Compatibility Check:
1. Pre-mix 2.0 teaspoonfuls of this product with 8.0 teaspoonfuls of water (1:4 ratio) in a quart jar by adding
the water first and follow with this product. Mix thoroughly. If a second herbicide is to be used, double
the amount of water (1:8 ratio) and add the second herbicide after mixing this product first.
2. Then pour 1.0 pint of fluid fertilizer into the quart jar and shake well.
3. Allow to stand for 5 minutes.
ONLY USE THIS COMPATIBILITY CHECK WHEN MIXING WITH FLUID FERTILIZERS.
Interpretation of Results: If the solution in the jar appears to be uniform, without signs of agglomeration, or without
a separation of an oily film on top of the fertilizer, the mixture may be used. If not, repeat the compatibility check
using twice the amount of water or add a compatibility agent to the water. If separation occurs, but the mixture can
be resuspended by shaking, then application is possible with good agitation in the spray tank.
Tank Mixing Guidelines:
1. Add the required amount of water and compatibility agent (if required) to the tank. Start agitation system
while adding this product and follow by adding the fluid fertilizer and agitate.
2. If a second herbicide is to be used, follow as above in 1, but use twice the amount of water. Start agitation,
add A342.01 and follow by adding the second herbicide, a nd then continue filling the tank with fluid
fertilizer.
3. Maintain continuous agitation to assure uniform spray mixture until the tank is emptied.
Commercial Impregnation and Application of A342.01 on Dry Bulk Fertilizer
Dry bulk fertilizer may be impregnated or coated with this product for application to established alfalfa and to
soybeans. All directions, cautions, and precautions on this label must be followed along with state regulations
relating to dry bulk fertilizer blending, impregnating and labeling.
Impregnation: To impregnate, use a system consisting of a belt, conveyor, or closed drum which is used for dry bulk
fertilizer blending. Any commonly used fertilizer can be impregnated with this product except ammonium nitrate,
or fertilizers containing ammonium nitrate, potassium nitrate, or sodium nitrate. Do not use on powder limestone.
Apply using a minimum of 200 pounds dry bulk fertilizer pe r acre and up to a maximum of 450 pounds per acre. To
impregnate or coat dry bulk fertilizer, mix this product with sufficient water to form a sprayable slurry. The delivery
nozzles must be directed to deliver a fine spray toward the fertilizer for thorough coverage while avoiding spray
contact with mixing equipment. Uniform impregnation of this product to dry bulk fertilizer will vary and if the
absorptivity is not adequate, an absorptive powder may be added to produce a dry, free-flowing mixture. Micro-
Cel
® is the recommended absorbent powder. When another herbicide is used with this product, mix and impregnate
immediately.
Apply immediately after impregnation unless experience has shown that impregnated fertilizer can be stored
without becoming lumpy and difficult to spread.
9
Rates: Select the specified rate of this product per acre from the appropri ate section of this label and refer to the
formula below to determine the amount of this product wh ich is to be impregnated on a ton of dry bulk fertilizer
based on the amount of fertilizer which will be distributed on 1 acre.
Lb A342.01 x 2000 Lb Fertilizer = Lb A342.01
Acre Acre Ton of Fertilizer
Application: Uniform application is essential for satisfactory weed control. Accurate calibration of fertilizer
application equipment is essential for uniform distribution to the soil surface. Apply ½ the specified rate and overlap
50% or double apply by splitting the middles to obtain the best distribution pattern.
If fertilizer materials are excessively dusty, use diesel oil or other suitable additive to reduce dust prior to
impregnation, as dusty fertilizer will result in poor distribu tion during application. Crop injury and/or poor weed
control may occur where the impregnated fertilizer is not uniformly applied.
Incorporation and Combination Uses: When this product is to be used in combination with another herbicide,
follow directions on this label for combinations, rates, crops, incorporation, and special precautions.

Extended Split-Shot Application
(Includes No-till, Reduced-till, Ridge-till, Strip-till, Mulch-till)
An early preplant (surface-applied or shallow incorporated) application of this product tank mixed with either
metolachlor or alachlor, followed by a preemergence surface application of this product tank mixed with metolachlor
or alachlor after planting but prior to soybean emergence, will control more broadleaf and grass weeds in soybeans
than either herbicide used alone.
An Extended Split-Shot application will decrease the need fo r tillage and/or contact herbicides for the control of
existing vegetation prior to planting, while providing residual control of weeds after planting.
When an Extended Split-Shot application of this product with metolachlor or alachlor is used, the preplant tank mix
combination may be applied 15 to 30 days prior to planting soybeans. Follow directions on the label accompanying
the product for Split-Shot applications from 0 to 14 days before planting.
Where a rate range is specified, use the higher rate (a) in fields with a history of severe weed pressure, (b) when the
time between early preplant tank mix and preemergence overlay applications the maximum 30 days, (c) when the
organic matter content of the soil is at the upper end of the indicated range, (d) when heavy crop residues are
present on the soil surface, and/or I when the early preplant tank mix applic ation is shallow incorporated (e.g., use
2.0 to 2.5 quarts alachlor in the early preplant tank mix when surface applied and use 2.5 to 3.0 quarts alachlor when
the tank mix is to be lightly incorporated).
When weeds exceed 1 to 1-1/2 inches in height or diameter at application, use a contact herbicide, such as
glyphosate (glyphosate) or paraquat.

Postemergence Directed Spray Applications
A342.01 can be applied in postemergence directed sprays to soybeans for control of certain weeds which escape
preplant or preemergence herbicide applications and for control of additional flushes of weeds that may occur after
soybeans have emerged. Postemergence directed sprays of A342.01 can be applied to soybeans in addition to a
preemergence or preplant application of A342.01 according to label directions.
Weeds Controlled: A342.01, applied postemergence to soybeans as a directed spray according to directions on this
label, will control the following at rates shown (broadcast basis) when grasses and common ragweed are less than 1
inch tall and other broadleaves are less than 3 inches tall:
0.3 Pound per Acre
Carpetweed (Mollugo 31olemonium31evertcillata) Mexicanweed (Caperonia castaniifolia)
Cocklebur (Xanthium pensylvanicum) Pigweeds ( Amaranthus spp.)
Crabgrass (Digitaria spp.) Purslane ( Portulaca oleracea)
Dayflower (Commelina spp.) Sicklepod ( Cassia obtusifolia)
32
Florida beggarweed (Desmodium tortuosum) Velvetleaf ( Abutilon theophrasti)
0.3 to 0.6 Pound per Acre
Prickly sida/Teaweed (Sida spinosa) Sesbania ( Sesbania spp.)

(broadcast basis)
Apply proper dosage using 10.0 to 40.0 gallons of water per acre as a directed spray in a 6- to 8-inch band on each
side of the row after soybeans are 8 inches tall and before broadleaf weeds are 3 inches tall and before grasses and
Common ragweed are 1 inch tall. For best results, the spray must cover weed foliage with minimum or no contact
with soybean foliage. Add a nonionic surfactant such as Activator 90 or Liberate
® to the spray mixture to obtain
better wetting of weed leaf surfaces. To determine the correct dosage of A342.01 for a band application see “Band
Application” under the “Product Information” section in the front of this label.
If necessary, a second postemergence directed spray application can be made after 7 days.

vines for feed or forage within 70 days of last application.
Restrictions:
x Do not feed or graze green soybean vines. Pre-harvest Interval (PHI): Do not harvest soybeans or use dry
soybean vines for feed or forage within 70 days of last application.
Precautions (Directed Postemergence):
x Do not apply directly to soybeans or serious crop injury will occur.
x Do not allow spray to contact more than the lower ¼ to 1/3 of soybean plants. Soybean leaves contacted
by the spray will be killed.
x Do not apply A342.01 postemergence to sensitive soybean varieties.
x See “Precautions” in the front of this label.
x To avoid injury to other crops or desirable plants from spray drift, sprayer pressure must not exceed 30 psi
and the sprayer must be fitted with nozzles no smaller than 8002 T-Jet® (or equivalent).

POTATOES
A342.01 may be used in ground, aircraft or specified chemigation equipment as a preemergence and/or
postemergence application to potatoes. Early maturing smooth skinned white and all red skinned varieties may be
injured with postemergence applications. The varieties Atlantic, Bellchip, Centennial, Chipbelle and Shepody are
sensitive to A342.01. Avoid postemergence applications on these varieties. Preemergence applications on these
varieties may cause crop injury under adverse weather conditions, on coarse soils, under high soil pH, with higher
rates per acre and with mechanical incorporation.
33
Ground Application: A342.01 may be used with ground spray equipment applied as a preemergence and/or
postemergence application for control of the listed grass and broadleaf weeds in potatoes. Apply as a uniform
broadcast at 20.0 or more gallons per acre.
Aerial Application: A342.01 may be applied in aerial spray equipment as a preemergence and/or postemergence
application at 5.0 or more gallons per acre.
Chemigation: A342.01 may be applied preemergence and/or early postemergence to potatoes using center pivot,
solid set and lateral roll systems. Apply specified dosage in ¼ to ¾ inch of water per acre (1/4 to ½ inch on sandy
soil) as a continuous injection in self-propelled systems or apply in the last 15 to 30 minutes of the set in other
systems. Be sure all the A342.01 pounds per acre has been flushed from the lines before shutting down the system.

FIELD CORN
Postemergence Application
A342.01 may be used for control of selected broadleaf weeds when applied as a tank mix combination with certain
broadleaf herbicides presently registered for post-emergence use in field corn. Herbicides which may be tank mixed
with A342.01 include:
2,4-D Bromoxynil Bentazon + atrazne Dicamba
Atrazine Bromoxynil + atrazine
(Premix)
Imazethapyr* Dicamba + atrazine
Bentazon Flumiclorac
*Use only on imazethapyr resistant/tolerant corn hybrids (IMI-Corn®).
Application: A342.01 may be applied to field corn after crop emergence until just prior to tasseling. Broadcast
applications may be made with ground or aerial equipment. For optimum weed control, apply treatments when
weeds are small and actively growing, but before reachi ng the maximum heights listed in the Weeds Controlled
table.
Postemergence Broadcast Application
Ground Application: Adjust nozzle height above crop and weed canopy to ensure uniform spray coverage. Increase
gallonage with increasing weed size and population density.
For tank mixes of A342.01 plus atrazine, bentazon, Laddock S-12, brom oxynil, bromoxynil + atrazine, imazethapyr,
flumiclorac, or 2,4-D amine formulations, use flat fan nozzles spaced a maximum of 20 inches apart. Best results are
achieved using a minimum spray volume of 10.0 gallons per acre and spray pressure from 20 to 40 psi.
For A342.01 tank mixes with Clarity, dicamba, dicamba + atrazine, or 2,4-D low volatile ester formulations, use drift-
reducing nozzles which are specifically designed to produce coarse sprays and reduce the amount of driftable fines.
Additional measures which will help avoid potential drift to sensitive crops and plants include a minimum spray
volume of 20.0 gallons per acre and keeping spray pressures at or below 20 psi unless otherwise specified by the
nozzle manufacturer.
For further precautions and additional instructions and recommendations, consult the tank mix partner’s label.
Aerial Application: Apply in a minimum spray volume of 3.0 gall ons per acre. For opti mum spray coverage and
distribution, use a minimum of 5.0 gallons per acre and a maximum pressure of 40 psi. Use a boom and nozzle
configuration which will provide a uniform deposition pattern and coverage with low drift potential. Avoid overlaps
to prevent potential crop injury. Do not apply near sensitive crops or sensitive plants growing near the treated area.
Do not apply when wind speed is greater than 10 mph or when winds are moving towards sensitive crops or plants.
To avoid drift hazards, applicator must follow the most restrictive labeling of the products used in a tank mix. Refer
to the appropriate tank mix partner’s label for further precautions and recommendations.
Post Directed Application
A342.01 in tank mix combinations with 2,4-D, bromoxynil or dicamba may be applied post directed to field corn.
Use drop nozzles and appropriate spacing to direct spray below the corn whorl and upper leaves. The top of the
target weed canopy must be sufficiently below the whorl and upper leaves of the crop to permit this application and
provide adequate spray coverage. The height differential required between the crop and weed canopy will depend
on the specific equipment used. Apply before tassel emergence. For further precautions and additional
recommendations, refer to the appropriate tank mix partner’s label.
Adjuvants
43
The adjuvant types listed below may be utilized with certain A342.01 tank mix combinations. Consult the tank mix
section for the appropriate adjuvant and rate. Use of other adjuvants or rates not listed on this label may result in
severe leaf burn, crop stunting, and/or stand reduction. Use only adjuvants which are exempt from tolerance
requirements under 40 CFR 180.1-001.
UAN (urea ammonium nitrate) is commonly referred to as 28, 30, or 32% N.
Ammonium sulfate (spray grade) may be used as an alternative to UAN with certain tank mix combinations.
Non-ionic surfactants should contain at least 80% active ingredient.
DO NOT USE crop oil concentrate (COC) or any adjuvant containing vegetable or petroleum oils with any A342.01
tank mixtures as severe leaf burn, crop stunting, and/or stand reductions may occur.
Rainfastness
A342.01 will not reduce rainfastness of the listed tank mix partners. Refer to the individual product labels for
rainfastness recommendations.
Sprayer Cleanup
Refer to each tank mix partner’s label and the Sprayer Cleanup section of the A342.01 label for specific instructions
on cleaning spray equipment. Special attention should be given to the required cleanup procedures for 2,4-D,
dicamba and dicamba + atrazine.
Restrictions:
x Do not use on corn grown for seed, sweet corn, popcorn, or white corn.
x Do not apply more than 0.25 pound active ingredient metribuzin (5.3 ounces A342.01) per acre per use
season.
x Do not apply when field corn is under stress (see Stress statement below).
x Do not use aerial applications if sensitive crops or plants are growing in the vicinity of the area to be treated.
x Do not allow spray drift onto sensitive crops or plants.
x Do not use on sand, loamy sand or sandy loam soils that have less than 0.5% organic matter.
x Do not use on sand or loamy sand soils in Washington, Oregon or Idaho or crop injury may occur.
x Observe all precautions and limitations on labeling of all products used in the tank mixtures.
Stress is any condition or combination of conditions which im pairs normal crop growth. Weather, disease, insect
damage, fertility or other factors may cause stress. Applicat ions made before or after the corn is under stress from
these factors or from periods of prolonged cool, wet and cloudy weather or widely fluctuating day and nighttime
temperatures, may result in temporary leaf burn, yellowing and/or stunting of the crop. Recovery from damage is
generally rapid with no lasting effects on new growth. Under extreme stress, stand reductions may occur.
Feeding Restrictions: Pre-harvest Interval (PHI): Field corn treated with A342.01 may be grazed or harvested for
silage or grain 60 days after treatment. Follow the most restrictive preharvest interval on the labels of the products
used in the tank mixtures.

GARBANZO BEANS (Chickpeas)
(California, Idaho, Oregon and Washington)
Special Conditions of Sale for Use on Garbanzo Beans (Chickpeas): The following directions for use were developed
under the direction of IR-4 (government minor crops use program). Buyer is advised that Atticus, LLC makes no
assurances regarding satisfaction with the product and that to the extent consistent with applicable law all risks or
crop injury or product performance are assumed by the Buyer.
A342.01 may be used as a preemergence application for the suppression of certain broadleaf weeds in garbanzo
beans.
WEEDS SUPPRESSED*:
Common chickweed
Common lambsquarters
Dog fennel (Mayweed)
Field pennycress henbit
Pigweed
Shepherd’s-purse
Wild mustard
*Suppression is a reduction in weed size and growth compared to a non-treated area in the same field. A342.01
used alone will not control triazine-resistant weed species.
Broadcast Applications
Crop A342.01 Lb/A
Garbanzo beans 0.3 to 0.5
Apply specified dosage in a single preemergence application using 10.0 to 40.0 gal of
water/A with ground spray equipment. Apply before or after planting but before crop
emergence. Thorough incorporation, either by rainfall or by mechanical means, is
essential for weed suppression. Under dry conditions, incorporate A342.01 into the top
1 to 2 inches of soil with spike harrows, or similar shallow incorporation equipment, then
cross harrow to ensure uniform soil incorporat ion. Where soil surface is moist at the
time of application and rain follows before weed emergence, a broadcast application
should provide adequate weed suppression.
Use on coarse-textured soils, sandy soils or any soil with less than 1.5% organic matter
will likely cause crop injury. Use the higher rate on fine textured soils (high in clay or
organic matter) and in fields with a history of high weed populations.
Restrictions:
50
x Crop injury may result if crop is under stress conditions caused by cold weather, poor soil fertility, diseases
or insect damage.
x Do not use on clay knobs or poorly covered subsoils.
x Do not apply preemergence on shallow seedlings less than 2 inches deep.
x Do not graze or feed treated vines to livestock within 40 days after application.
Precautions:
x Crop injury may result if application is followed by he avy rain. Avoid application of more than ½ inch of
irrigation within one month after application of A342.01, or crop injury may occur.
x This treatment may cause some chlorosis or minor necrosis. Because garbanzo bean varieties may vary in
their susceptibility to A342.01, determine crop tolerance prior to ad option as a field scale practice to
prevent possible injury.
LENTILS AND PEAS
(Idaho, Oregon, Washington, Montana and North Dakota)
A342.01 may be used as a preemergence and postemergence application for the suppression of certain broadleaf
weeds in lentils and peas.

*Suppression is a reduction in weed size and growth compared to a non-treated area in the same field.
**Preemergence application only.
Preemergence Application: Make a single preemergence application of A342.01 at 0.25 to 0.5 pound per acre per
crop year. Apply in 10.0 or more gallons of water per acre with ground spray equipment or 5.0 or more gallons of
water per acre with aerial spray equipment. Apply A342.01 before or after planting. Thorough incorporation, either
by rainfall or by mechanical means, is essential for weed suppression. Under dry conditions, incorporate A342.01
into the top 1 to 2 inches of soil with spike harrows, or similar shallow incorporation equipment, then cross harrow
to ensure uniform soil incorporation. Where soil surface is moist at the time of application and rain follows before
weed emergence, a broadcast application should provide adequate weed suppression.
Use the higher rate on fine textured soils (high in clay or organic matter) and in fields with a history of high weed
populations.
A342.01 may be applied pre- or post-plant incorpor ated as a tank mix combination with Far-Go
® 4EC. Follow the
Direction for Use Statements on both product labels.
Postemergence Application: One postemergence application may be made per season. Use 0.16 to 0.3 pound of
A342.01 per acre on lentils and spring peas . On winter peas , use 0.25 to 0.3 pound of A342.01 per acre. For
suppression of Dog fennel, use 0.3 pound A342.01 per acre. Apply specified dosage in 20.0 or more gallons of water
per acre with ground spray equipment or 5.0 or more gallons of water per acre with aerial spray equipment. Do not
exceed 40 psi with ground spray equipment. Apply as a broadcast spray when weeds are small (less than 2 inches
in height or diameter) and before crop is 6 inches tall.
Precautions:
51
x Temporary chlorosis of the crop may occur. There is an added risk of crop injury if a postemergence
application is made following a previous preemergence or post plant incorporated A342.01 application.
x Do not apply over very moist soils or wet crop foliage. Do not apply postemergence applications within 3
days after periods of cook, wet, or cloudy weather or crop injury may occur.
x Do not apply within 24 hours of treatment with other pesticides.
x Crop injury may result if crop is under stress conditi ons caused by cold weather, low fertility, disease or
insect damage.
x Crop injury may also result if application is followed by heavy rain.
x Do not apply to “Estin” lentils.
x This treatment may cause some chlorosis or minor necrosis. Because lentil and pea varieties may vary in
their susceptibility to A342.01, determining crop tolerance prior to ad option as a field scale practice is
suggested to prevent possible injury.
Restrictions (Lentils and Peas):
x Do not apply more than 0.6 pound A342.01 per acre per year.
x Do not use on coarse-textured soils, sandy soils or soils with less than 1.5% organic matter.
x Do not use on clay knobs or poorly covered subsoils.
x Do not apply on shallow seedlings less than 2 inches deep (preemergence only).
x Pre-harvest Interval (PHI): Do not apply within 50 days of harvest of peas, or within 75 days of harvest of
lentils.
x Do not graze or feed treated vines to livestock within 40 days after application.
Maintain continuous spray tank agitation to keep material in suspension. Avoid overlapping and shut off spray
booms while turning, slowing or stopping, or crop injury may occur.

CEREALS
(Spring and Winter Barley and Winter Wheat)
A342.01 may be used for control or suppression of ce rtain grasses and broadleaf weeds when applied
postemergence to spring and winter barley or winter wheat. A342.01 alone and several tank mixture treatments
are recommended for use in the following states: Arkansas, Georgia, Idaho, Illinois, Indiana, Kansas, Kentucky,
Louisiana, Mississippi, Missouri, Montana, Nevada, Ohio, Oklahoma, Oregon, Tennessee, Texas, Utah, Washington.
Mixing: See the “ Product Information ” section of this label for specific mixing procedures. When tank mixing,
carefully follow the instructions on this label. Refer to the other product labels registered for use in barley and
winter wheat for additional use directions, rates, weeds controlled and restrictions.
Application: A342.01 may be applied by aerial or ground application equipment. Use a minimum spray volume of
2.0 gpa by air and 10.0 gpa by ground. Uniform spray coverage is necessary to obtain optimum weed control and to
minimize potential for crop injury. Do not exceed rates specified on this label. Do not apply A342.01 through any
type of irrigation equipment. Apply A342.01 when the crop is healthy and actively growing. A342.01 may be applied
more than once per crop season. Allow a minimum of 21 da ys between applications if wheat is actively growing of
allow 45 days between applications if wheat is growing in adverse conditions, has entered dormancy or is stressed
due to frost damage, drought or excessive moisture. Do not use on soils containing less than 0.75% organic matter.
Do not apply more than a total of 10.66 ounces A342.01 (8.0 ounces active ingredient) per acre per year. On irrigated
cereals, do not apply more than 0.5 inch of water for the first irrigation, the maximum amount for each additional
irrigation must not exceed 1 inch. Allow a minimum of 14 days between the first irrigation and subsequent
irrigations.
Performance Factors: Weed control may not be observed for 2 to 4 weeks under normal growth conditions and for
4 to 6 weeks under very dry conditions. Moisture (at least ½ inch) is required within 2 to 3 weeks after application
to move A34201 into the weed root zone. Lack of adequate moisture after application may result in poor or erratic
weed control. Control or suppression of listed weeds is dependent on weed size at time of application. Control or
suppression may be reduced if broadleaf weeds are taller than 1 inch or grasses have more than 2 leaves.
Tank Mixtures: A342.01 may be tank mixed with metsulfuron methyl, triasulfuron, chlorsulfuron + metsulfuron,
Chlorsulfuron, thifensulfuron-methyl + tribenuron methyl , 2,4-D, MCPA, dicamba, or bromoxynil herbicides. A
nonionic surfactant containing at least 80% active ingredient may be used in A342.01 tank mixes with sulfonylurea
herbicides (metsulfuron methyl, trisulfuron, chlorsulfuron + metsulfuron, Chlorsulfuronand thifensulfuron-methyl +

For Weed Control in a Wheat/Fallow/Wheat Rotation
(Idaho, Oregon, Utah and Washington Only)
A342.01 may be applied to provide weed control during the fallow period after wheat harvest or in the spring before
winter wheat is planted. Winter wheat can be seeded 4 months (120 days) after spring application. Mechanical
tillage or the application of a contact herbicide may be re quired to control weeds germ inating prior to seeding of
winter wheat. Best results will be obtained where straw and chaff are evenly distributed across the field.
For specified application information see the “Product Information” section in the front of this label.
Where weed growth is present at application time, A342.01 should be applied with paraquat or other contact
herbicide. Refer to the other product label registered for additional directions, rates, and weed species controlled.

*Note: Since control of these weeds may be variable depending on moisture following application, the higher
labeled rate should be used.
After Harvest Application (Fall Fallow): A342.01 may be applied to wheat stubble after harvest in the fall. Apply
0.6 to 0.83 pound per acre broadcast before weeds emerge. Use higher rate for longer weed control or for weeds
designated as requiring the higher rate for control. Rainfall (1/2 inch or more) is necessary for herbicide activation.
Restrictions: Do not plant crops in treated areas for at least 10 months following fall applications.
A342.01 may be applied at 0.6 to 0.83 pound per acre as directed above for a fall application. If other vegetation is
present at the time of application, use a contact herbicide.
Spring Application (Summer Fallow): A342.01 may be applied to wheat stubble in the spring. Apply 0.5 to 0.6
pound per acre broadcast before weeds emerge in the spring. Use higher rate for longer weed control or weeds
designated as requiring higher rate for control. Rainfall (1/2 inch or more) is necessary for herbicide activation.
Restrictions: Do not graze treated fields.
Do not plant spring seeded cereals following fall applications fallow.
Where A342.01 was applied in the fall, do not apply A342.01 in the spring.
For Weed Control in a Fallow Rotation with Barley and Wheat
(Colorado, Kansas, Montana, Nebraska and Wyoming Only.)
A342.01 may be applied to provide weed control during the fallow period after wheat or barley harvest or in the
spring before planting of winter wheat or barley. Mechanical tillage or the application of a contact herbicide may
be required to control weeds germinating prior to seedling of winter wheat or barley.
For specific application information see the “Product Information” section in the front of this label.
Where weed growth is present at application time, A342.01 should be applied with paraquat, glyphosate, or other
contact herbicide. Refer to the other product label registered for additional directions, rates, and weed species
controlled. Do not plant crops in treated areas earlier than 10 months following Fall applications.

PRECAUTIONARY STATEMENTS
HAZARDS TO HUMANS AND DOMESTIC ANIMALS
CAUTION
Harmful if swallowed or absorbed through skin. Causes moderate eye
irritation. Avoid contact with eyes or clothing. Prolonged or
frequently repeated skin contact may cause allergic reactions in some
individuals.
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 apply when
weather conditions favor drift from areas treated. Do not
contaminate water when disposing of equipment washwaters or
rinsate.
Groundwater Advisory: Metribuzin is a chemical which can travel
(seep or leach) through soil and can contaminate groundwater which
may be used as drinking water. Metribuzin has been found in
groundwater as a result of agricultural use. Users are advised not to
apply metribuzin where the water table (groundwater) is close to the
surface, and where the soils are very permeable, i.e., well-drained
soils such as loamy sands. Your local agricultural agencies can provide
further information on the type of soil in your area and the location
of groundwater.
