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: 
• Scout application site before and after herbicide applications. 
• Start with a clean application site, suing either a burndown herbicide application or tillage. 
• Control weeds early when they are relatively small. 
• Add other herbicides (e.g. a selective and/or a residual herbicide) and cultural practices (e.g., tillage 
or crop rotation) where appropriate. 
• 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. 
• Control weed escapes and prevent weeds from setting seeds. 
• Clean equipment before moving from field to field to minimize the spread of weed seed or plant parts. 
• 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.

PRODUCT INFORMATION 
Mixing: It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are 
registered for the intended use. Read and follow the applicable restrictions and limitation and directions for 
use on all product labels involved in the tank mixing. Users must follow the most restrictive directions for 
use and precautionary statements on each product in the tank mixture. When using this product, make 
sure the sprayer is completely clean, free of rust or corrosion which occurs from winter storage. Examine 
strainers and screens to be sure the sprayer is clean from previously used pesticides. 
Keep any tank mix containing this product agitated and sprayed out immediately. Do not allow tank mixes 
to stand for prolonged periods of time. 
The proper mixing procedure for A342.01 alone or in tank mix combinations with other herbicides is: 
1. Fill the spray tank 1/4 to 1/3 full with clean water. 
2. Add specified rate of this product while recirculating and with agitator running. 
3. Follow the triple rinse procedure described under “ Storage And Disposal ” to ensure that all 
product is removed from the container. 
4. Mix thoroughly and add clean water to fill spray tank to desired level. 
5. Add the other herbicide to tank last and agitate thoroughly. 
6. Continue agitation during application and until sprayer tank is empty. 
Soil Texture: As used on this label, “coarse soils” are loamy sand or sandy loam soils. “Medium soils” are 
loam, silt loam, silt, sandy clay, or sandy clay loam. “Fine soils” are silty clay, silty clay loam, clay, or clay 
loam. Silty clay loam soils are transitional soils and may be classified as medium textured soils in some 
regions of the U.S. 
PRODUCT RESTRICTIONS 
• Do not rotate any crop not listed on this label for 18 months following application. 
• Do not allow sprays to drift on to adjacent desirable plants. 
• Do not use on other crops grown for food or forage. 
• For all uses: Low-pressure, high-volume hand-wand equipment is prohibited. 
 
CHEMIGATION 
This product may be used for application through sprinkler irrigation equipment to potatoes, soybeans, 
tomatoes, and asparagus as directed on this label. Refer to the crop 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 residues 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 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 revolution and if 2 minutes were required to inject 
1.0 gallon, then a total of 600 gallons of product-water mixture 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 functional 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

6 
 
may result. Where sprinkler distribution patterns overlap excessively, crop injury may result. Allow 
sufficient time for pesticide to be flushed through all lines 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 spray drift. The applicator and the 
grower are responsible for considering all these factors when making decisions. 
The following drift management requirements must be followed to avoid off -target drift movement from 
aerial applications to agricultural field crops. These requirements do not apply to forestry applications, 
public health uses or to applications using dry formulations. 
1. The distance of the 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 potential is to apply large droplets. 
The best drift management strategy is to apply the largest droplets that provide sufficient coverage and 
control. Applying larger droplets reduces drift potential, but will no t prevent drift if applications are made 
improperly, or under unfavorable environmental conditions (see Wind, Temperature and Humidity and 
Temperature Inversions). 
Controlling Droplet Size 
• Volume – Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with 
higher rated flows produce larger droplets. 
• Pressure – Do not exceed the nozzle 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. 
• Number of Nozzles – Use the minimum number of nozzles that provide uniform coverage. 
• Nozzle Orientation – Orienting nozzles so that the spray is released parallel to the airstream 
produces larger droplets than other orientations and is the recommended practice. Significant 
deflection from horizontal will reduce droplet size and increase drift potential. 
• Nozzle Type – Use a nozzle type that is designed for the intended application. With most nozzle 
types, narrower spray angles produce larger droplets. Consider using low -drift nozzles. Solid 
stream nozzles oriented straight back 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.

7 
 
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.). 
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 gener ator. 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 drift 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, use 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 overlapping

8 
 
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 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 combinations 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 th is 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, and 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. 
 
Formatted: Font: Bold
Deleted: special

9 
 
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 per 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 direct ed 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. 
Rates: Select the specified rate of this product per acre from the appropriate section of this label and refer 
to the formula below to determine the amount of this product which 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 distribution 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.

Activation: A minimum amount of soil moisture is required to activate this product. In areas of low rainfall, 
preemergence applications to dry soil should be followed with light irrigation of ¼ acre- inch of water. Do 
not apply heavy irrigation immediately after application. As with many surface- applied herbicides, weed 
control and crop tolerance may vary with rainfall and/or soil texture. 
Rate Ranges: Where a rate range is shown, use a lower rate on soils that are coarse- textured or low in 
organic matter. Use a higher rate on soils that are relatively fine-textured or high in organic matter. 
Replanting: If replanting is necessary in fields treated with this product as directed on this label, the field 
may be replanted to soybeans. When replanting use a minimum of tillage. Do not apply a second treatment 
as injury to soybeans may occur.

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 for 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 t he soil is at the upper end of the indicated range, (d) when 
heavy crop residues are present on the soil surface, and/or (e) when the early preplant tank mix application 
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. 
Refer to the metolachlor or alachlor label, and to appropriate sections of this label for additional information 
on soil preparation, herbicide application, weeds controlled, precautions, restrictions, limitations and

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 verticillata) Mexicanweed (Caperonia castaniifolia)

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 wed 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. 
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. 
Restrictions: 
• 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): 
• Do not apply directly to soybeans or serious crop injury will occur. 
• 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. 
• Do not apply A342.01 postemergence to sensitive soybean varieties. 
• See “Precautions” in the front of this label. 
• 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). 
• Do not apply under weather conditions which favor drift. 
 
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 vari eties 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. 
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. 
Weeds Controlled 
A342.01 applied to potatoes according to directions, will provide economic control of the following weeds. 
For optimum control, applications should be made before weeds are 1 inch tall. (See NOTE).

• Do not plant sensitive crops such as onions, lettuce, cole crops and cucurbits during the next 
growing season following A342.01 application. 
Postemergence applications may cause some chlorosis or minor necrosis. These symptoms may be more 
severe if seed-piece decay is occurring or if growing conditions favor crop stress. 
Postemergence applications may be made only on russet or white skinned varieties that are not early 
maturing. 
Potato varieties may vary in their response to herbicide applications. When using A342.01 for the first time 
on a particular variety, always determine crop tolerance before using on a field scale. 
Certain cereal varieties are sensitive to A342.01 (see cereal section of this label for sensitive varieties) and 
should not be planted during the next growing season unless the following cultural practices occur: 
1. Potato vines left in rows as a result of harvest must be uniformly distributed over the soil surface 
prior to plowing, and 
2. Plow with a moldboard plow to a depth sufficient to mix the upper 8 inches of soil.

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 reaching 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, bromoxynil, 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 gallons per acre. For optimum 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 
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: 
• Do not use on corn grown for seed, sweet corn, popcorn, or white corn. 
• Do not apply more than 0.25 pound active ingredient metribuzin (5.3 ounces A342.01) per acre per 
use season. 
• Do not apply when field corn is under stress (see Stress statement below). 
• Do not use aerial applications if sensitive crops or plants are growing in the vicinity of the area to 
be treated. 
• Do not allow spray drift onto sensitive crops or plants. 
• Do not use on sand, loamy sand or sandy loam soils that have less than 0.5% organic matter. 
• Do not use on sand or loamy sand soils in Washington, Oregon or Idaho or crop injury may occur. 
• Observe all precautions and limitations on labeling of all products used in the tank mixtures. 
Stress is any condition or combination of conditions which impairs normal crop growth. Weather, disease, 
insect damage, fertility or other factors may cause stress. Applications 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 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 
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 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: 
• Crop injury may result if crop is under stress conditions caused by cold weather, poor soil fertility, 
diseases or insect damage. 
• Do not use on clay knobs or poorly covered subsoils. 
• Do not apply preemergence on shallow seedlings less than 2 inches deep. 
• Do not graze or feed treated vines to livestock within 40 days after application. 
Precautions: 
• Crop injury may result if application is followed by heavy rain. Avoid application of more than ½ 
inch of irrigation within one month after application of A342.01, or crop injury may occur.

• 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 adoption 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. 
Weeds Suppressed* 
Common chickweed** 
Corn spurry 
Dog fennel 
Field pennycress 
Henbit** 
Lambsquarters 
Pennsylvania smartweed 
Pineapple weed 
Prostrate knotweed 
Redroot 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. 
**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 incorporated 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: 
• Temporary chlorosis of the crop may occur. Ther e is an added risk of crop injury if a 
postemergence application is made following a previous preemergence or post plant incorporated 
A342.01 application. 
• 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. 
• Do not apply within 24 hours of treatment with other pesticides. 
• Crop injury may result if crop is under stress conditions caused by cold weather, low fertility, disease 
or insect damage. 
• Crop injury may also result if application is followed by heavy rain. 
• Do not apply to “Estin” lentils.

• 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 adoption as a field scale 
practice is suggested to prevent possible injury. 
Restrictions (Lentils and Peas): 
• Do not apply more than 0.6 pound A342.01 per acre per year. 
• Do not use on coarse-textured soils, sandy soils or soils with less than 1.5% organic matter. 
• Do not use on clay knobs or poorly covered subsoils. 
• Do not apply on shallow seedlings less than 2 inches deep (preemergence only). 
• Pre-harvest Interval (PHI): Do not apply within 50 days of harvest of peas, or within 75 days of 
harvest of lentils. 
• 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.

• Do not use hot caps on tomatoes within 7 days before or at any time after application of A342.01. 
Do not treat seeded tomatoes until plants have reached the 5- to 6-leaf stage or severe crop injury 
may occur. 
• Crop injury or delayed maturity may result from broadcast or directed spray applications if tomatoes 
are growing under stress conditions such as periods of drought or cool, wet and cloudy weather 
preceding application. 
• For newly introduced tomato varieties with unknown tolerance to A342.01, treat only a small area 
to determine if A342.01 can be used without injury to crop. 
 
CEREALS 
(Spring and Winter Barley and Winter Wheat) 
A342.01 may be used for control or suppression of certain 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 r ates 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 days 
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 ta ller 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 + t ribenuron 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 + tribenuron methyl ). Do not use a crop oil 
concentrate or any adjuvant containing vegetable or petroleum oils with any A342.01 mix as crop injury 
may result. Additional pesticides may also be tank mixed with A342.01 unless specifically prohibited on 
the mix products’ label. In some instances, combinations with organophosphate insecticides may cause

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 requir ed to control weeds germinating 
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.
