MIXING AND SPRAYING: Ensure the spray tank is clean and free of rust or corrosion from winter 
storage or residues from previous spray treatments. Fill the spray tank 1/4 to 1/3 full with clean water. 
Make sure the tank agitation system is operating while adding products. Add specified amount of Omni 
Brand Metribuzin 4SC into the spray tank while filling with water to the desired level. Operate the agitator 
while mixing. If other materials are added to the spray tank, the Omni Brand Metribuzin 4SC should be 
thoroughly dispersed prior to the addition of other materials. 
 
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read 
and follow the applicable restrictions and limitations and directions for use on all product labels involved in 
tank mixing. Users must follow the most restrictive directions for use and precautionary statements of 
each product in the tank mixture.

4
Filename:OmniBrandMetribuzin4SC(5905ͲARE)022218CLN
Do not tank mix with products containing a prohibition against tank mixing. Continue to operate the 
agitation system until the spray tank has been emptied. Any tank mix containing Omni Brand Metribuzin 
4SC should be kept agitated and sprayed out immediately. Do not allow tank mixes to stand for prolonged 
periods of time. 
 
CHEMIGATION 
Apply Omni Brand Metribuzin 4SC only through sprinkler irrigation equipment to potatoes, soybeans, 
tomatoes, and asparagus as directed on this label. Refer to the crop sections of this label for 
recommended rates, weeds controlled or suppressed, restrictions, and special precautions. Omni Brand 
Metribuzin 4SC is to be applied only through 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 non-uniform distribution of treated water. 
Calibration (Center Pivot and Self-Propelled Lateral Move Systems): Sprinkler irrigation systems 
must be accurately calibrated for application of Omni Brand Metribuzin 4SC. 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 number of minutes required to make one complete revolution while applying 1/4 to 3/4 
inch of water per acre. 
2. With the system at operating pressure determine the exact number of minutes required to inject 
one gallon of water. 
3. Divide the time required for one revolution (step 1) by the time required to inject one 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 sufficient 
Omni Brand Metribuzin 4SC at the recommended rate to the nurse tank. 
Example: If 20 hours (1200 minutes) were required for one revolution and if 2 minutes were required to 
inject one gallon, then a total of 600 gallons of product-water mixture are required (1200 /2 = 600); to treat 
135 acres at 1 pint/acre, 135 pints (16 gallons and 7 pints) of Omni Brand Metribuzin 4SC are required. 
 
If you have questions about calibration, contact State Extension Service specialists, equipment 
manufacturers or other experts. Do not connect an 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 mix tank during mixing and application to assure a uniform suspension. 
Apply specified dosage in 1/4 to 3/4 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

5
Filename:OmniBrandMetribuzin4SC(5905ͲARE)022218CLN
recommended 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 and all nozzles before turning off irrigation 
water. To insure 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 
insure 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 3/4 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 must 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 not prevent 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 recommended pressures. For many nozzle 
types lower pressure produces larger droplets. When higher flow rates are needed, use higher 
flow rate nozzles instead of increasing pressure. 
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. Consider using low-drift nozzles. Solid 
stream nozzles oriented straight back produce the largest droplets and the lowest drift. 
BOOM LENGTH: For some use patterns, reducing the effective boom length to less than 3/4 of the 
wingspan or rotor length may further reduce drift without reducing swath width. 
APPLICATION HEIGHT: Do not make applications 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.)

6
Filename:OmniBrandMetribuzin4SC(5905ͲARE)022218CLN
 
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 direction and high inversion potential. NOTE: Local terrain can 
influence wind patterns. 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 
concentrations cloud (under low wind conditions) indicates an inversion, while smoke that moves upward 
and rapidly dissipates indicates good vertical air mixing. 
 
SENSITIVE AREAS: Omni Brand Metribuzin 4SC should only be applied 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 OMNI BRAND METRIBUZIN 4SC 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. 
 
GROUND APPLICATION: Apply the proper rate of Omni Brand Metribuzin 4SC in a minimum of 10 to 40 
gallons of spray mixture per acre broadcast. 
BANDED APPLICATION: Use proportionally less Omni Brand Metribuzin 4SC per acre in a band versus 
a broadcast application. For band application use 1/4 to 1 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 one-half of the broadcast rate of 
product. (2) To treat a 14-inch band on rows 42 inches apart, use one-third of the broadcast rate of 
product. 
AERIAL APPLICATION: Where permitted, apply specified rate in a minimum of 2 to 10 gallons of spray 
mixture per acre. Do not apply aerially when wind speed is greater than 10 mph. 
 
NOTE: Do not apply aerially when Omni Brand Metribuzin 4SC is tank mixed with Lasso®. 
FOR ALL APPLICATIONS OF OMNI BRAND METRIBUZIN 4SC: The sprayer must be accurately 
calibrated before applying Omni Brand Metribuzin 4SC. 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 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,

7
Filename:OmniBrandMetribuzin4SC(5905ͲARE)022218CLN
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 Omni Brand 
Metribuzin 4SC 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 one cup per 20 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 OMNI BRAND METRIBUZIN 4SC IN FLUID FERTILIZERS 
Omni Brand Metribuzin 4SC 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. 
Compatibility checks of Omni Brand Metribuzin 4SC and tank mix combinations which include Omni 
Brand Metribuzin 4SC should be made for each batch of fluid fertilizer because of the variability of these 
fertilizers. 
 
Compatibility Check: 
1. Pre-mix 2 teaspoonfuls of Omni Brand Metribuzin 4SC with 8 teaspoonfuls of water (1:4 ratio) in a 
quart jar by adding the water first and followed with Omni Brand Metribuzin 4SC. 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 Omni Brand Metribuzin 4SC first. 
2. Then pour 1 pint of fluid fertilizer into the quart jar and shake well. 
3. Allow to stand for 5 minutes. 
THIS COMPATIBILITY CHECK SHOULD ONLY BE USED 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. It is the pesticide user’s responsibility to ensure that all products are registered for the intended 
use. Read and follow the applicable restrictions and limitations and directions for use on all 
product labels involved in tank mixing. Users must follow the most restrictive directions for use 
and precautionary statements of each product in the tank mixture. 
2. Add the required amount of water and compatibility agent (if required) to the tank. Start agitation 
system while adding Omni Brand Metribuzin 4SC and follow by adding the fluid fertilizer and 
agitate. 
3. If a second herbicide is to be used, follow as above in 1, but use twice the amount of water. Start 
agitation and add Omni Brand Metribuzin 4SC and follow by adding the second herbicide, and 
then continue filling the tank with fluid fertilizer. 
4. Maintain continuous agitation to assure uniform spray mixture until the tank is emptied. 
COMMERCIAL IMPREGNATION AND APPLICATION OF OMNI BRAND METRIBUZIN 4SC ON DRY 
BULK FERTILIZER 
Dry bulk fertilizer may be impregnated or coated with Omni Brand Metribuzin 4SC for application to 
established alfalfa and to soybeans. All recommendations, cautions, and special precautions on this label 
must be followed along with state regulations relating to dry bulk fertilizer blending, impregnating and 
labeling.

8
Filename:OmniBrandMetribuzin4SC(5905ͲARE)022218CLN
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 Omni Brand 
Metribuzin 4SC except ammonium nitrate, potassium nitrate, or sodium nitrate. Do not use on powder 
limestone. 
Apply using a minimum of 200 lbs dry bulk fertilizer per acre and up to a maximum of 450 lbs per acre. 
To impregnate or coat dry bulk fertilizer, mix Omni Brand Metribuzin 4SC 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 Omni Brand Metribuzin 4SC 
to dry bulk fertilizer will vary and if the absorptivity is not adequate, an absorbent powder may be added to 
produce a dry, free-flowing mixture. Micro-Cel E (Johns-Manville Product Corporation) is the 
recommended absorbent powder. When another herbicide is used with Omni Brand Metribuzin 4SC 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 Omni Brand Metribuzin 4SC per acre from the appropriate section of 
this label and refer to the formula below to determine the amount of Omni Brand Metribuzin 4SC which is 
to be impregnated on a ton of dry bulk fertilizer based on the amount of fertilizer which will be distributed 
on one acre. 
 
Pt Omni Brand Metribuzin 4SC X 2000 lb Fertilizer = Pt Omni Brand Metribuzin 4SC 
 Per Acre Acre Ton of Fert. 
APPLICATION: Uniform application is essential for satisfactory weed control. Accurate calibration of 
fertilizer application equipment is essential for uniform distribution to the soil surface. The recommended 
method of application is to apply 1/2 the specified rate and overlap 50 percent or to 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 Omni Brand Metribuzin 4SC is to be used in 
combination with another herbicide, follow directions on this label for combinations, rates, crops, 
incorporation, and special precautions.

RESISTANCE-MANAGEMENT RECOMMENDATIONS 
For resistance management, Omni Brand Metribuzin 4SC is a Group 5 herbicide. Any weed population 
may contain or develop plants naturally resistant to Omni Brand Metribuzin 4SC and other Group 5 
herbicides. The resistant biotypes may dominate the weed population if these herbicides are used 
repeatedly in the same field. Appropriate resistance management strategies should be followed."
To delay herbicide resistance take one or more of the following steps: 
 
• Rotate the use of Omni Brand Metribuzin 4SC or other Group 5 herbicides within a growing season 
sequence or among growing seasons with different herbicide groups that control the same weeds in a 
field. 
 
• Use tank mixtures with herbicides from a different group if such use is permitted; where information on 
resistance in target weed species is available, use the less resistance-prone partner at a rate that will 
control the target weed(s) equally as well as the more resistance-prone partner. Consult your local 
extension service or certified crop advisor if you are unsure as to which active ingredient is currently less 
prone to resistance. 
 
• Adopt an integrated weed-management program for herbicide use that includes scouting and uses 
historical information related to herbicide use and crop rotation, and that considers tillage ( or other 
mechanical control methods), cultural ( e.g., higher crop seeding rates; precision fertilizer application 
method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties) 
and other management practices. 
 
• Scout after herbicide application to monitor weed populations for early signs of resistance development. 
Indicators of possible herbicide resistance include: (1) failure to control a weed species normally 
controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; 
(2) a spreading patch of non-controlled plants of a particular weed species; (3) surviving plants mixed with 
controlled individuals of the same species. If resistance is suspected, prevent weed seed production in 
the affected area by an alternative herbicide from a different group or by a mechanical method such as 
hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and 
tillage equipment when moving between fields, and planting clean seed. 
 
• If a weed pest population continues to progress after treatment with this product, discontinue use of this 
product, and switch to another management strategy or herbicide with a different mode of action, if 
available. 
 
• Contact your local extension specialist or certified crop advisors for additional pesticide resistance-
management and/or integrated weed-management recommendations for specific crops and weed 
biotypes. 
 
• For further information or to report suspected resistance, contact Helena Chemical Company at 901-
761-0050 or at www.helenachemical.com 
 
 
Fields should be scouted prior to application to identify the weed species present and their 
growth stage to determine if the intended application will be effective. 
Fields should be scouted after application to verify that the treatment was effective.
Suspected herbicide-resistant weeds may be identified by these indicators:

10
Filename:OmniBrandMetribuzin4SC(5905ͲARE)022218CLN
x Failure to control a weed species normally controlled by the herbicide at the dose applied, 
especially if control is achieved on adjacent weeds; 
x A spreading patch of non-controlled plants of a particular weed species; and 
x Surviving plants mixed with controlled individuals of the same species. 
 
Report any incidence of non-performance of this product against a particular weed species to your 
Helena Chemical retailer, representative or call 901-761-0050. If resistance is suspected, treat weed 
escapes with an herbicide having a different mechanism of action and/or use non-chemical means to 
remove escapes, as practical, with the goal of preventing further seed production. 
 
Plant into weed-free fields and keep fields as weed-free as possible. 
 
To the extent possible, use a diversified approach toward weed management. Whenever possible 
incorporate multiple weed-control practices such as mechanical cultivation, biological management 
practices, and crop rotation. 
 
Fields with difficult to control weeds should be rotated to crops that allow the use of herbicides with 
alternative mechanisms of action or different management practices. 
 
To the extent possible do not allow weed escapes to produce seeds, roots or tubers. Manage weed 
seeds at harvest and post-harvest to prevent a buildup of the weed seed bank. 
 
Prevent field-to-field and within-field movement of weed seed or vegetative propagules. Thoroughly clean 
plant residues from equipment before leaving fields. 
 
Prevent an influx of weeds into the field by managing field borders. 
 
Identify weeds present in the field through scouting and field history and understand their biology. The 
weed-control program should consider all of the weeds present. 
 
Difficult to control weeds may require sequential applications of herbicides with differing mechanisms of 
action. 
 
Apply this herbicide at the correct timing and rate needed to control the most difficult weed in the field. 
 
Use a broad spectrum soil-applied herbicide with a mechanism of action that differs from this product as a 
foundation in a weed-control program. Do not use more than two applications of this or any other 
herbicide with the same mechanism of action within a single growing season unless mixed with an 
herbicide with another mechanism of action with an overlapping spectrum for the difficult-to-control 
weeds. 

If resistance is suspected, treat weed escapes with an herbicide with a different MOA or use non-
chemical methods to remove escapes. 

Contact your local sales representative, crop advisor, or extension agent to find out if suspected resistant 
weeds to this MOA have been found in your region. If resistant biotypes of target weeds have been 
reported, use the application rates of this product specified for your local conditions. Tank mix products so 
that there are multiple effective mechanisms of actions for each target weed.

CEREALS (Spring and Winter Barley and Winter Wheat) 
 
Apply Omni Brand Metribuzin 4SC for control or suppression of certain grasses and broadleaf weeds 
when applied postemergence to spring and winter barley or winter wheat. Omni Brand Metribuzin 4SC 
alone and several tank mixture treatments are recommended for use in the following states: AR, GA, ID, 
IL, IN, KS, KY, LA, MS, MO, MT, NV, OH, OK, OR, TN, TX, UT, WA. 
Mixing: See the “Product Information” section of this label for specific mixing procedures. It is the 
pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and 
follow the applicable restrictions and limitations and directions for use on all product labels involved in 
tank mixing. Users must follow the most restrictive use directions for use and precautionary statements of 
each product in the tank mixture.

20
Filename:OmniBrandMetribuzin4SC(5905ͲARE)022218CLN
Application: Omni Brand Metribuzin 4SC may be applied by aerial or ground application equipment. Use 
a minimum spray volume of 2 gpa by air and 10 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 Omni Brand Metribuzin 4SC through any type of irrigation equipment. Apply Omni 
Brand Metribuzin 4SC when the crop is healthy and actively growing. Omni Brand Metribuzin 4SC may be 
applied more than once per crop season. 
Allow a minimum of 21 days between applications if wheat is actively growing or allow 45 days between 
applications if wheat is growing in adverse conditions, has entered dormancy or is stressed due to frost 
damage, disease, drought or excessive moisture. Do not use on soils containing less than 0.75% organic 
matter. Do not apply more than a total of 16 fluid ounces Omni Brand Metribuzin 4SC (8 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 should 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 1/2 inch) is required within 2 
to 3 weeks after application to move Omni Brand Metribuzin 4SC 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: Omni Brand Metribuzin 4SC may be tank mixed with Ally, Amber, Finesse, Glean FC, 
Harmony Extra, 2,4-D, MCPA, Igran, Banvel/Banvel SGF, Bronate or Buctril herbicides. A nonionic 
surfactant containing at least 80% active ingredient may be used in Omni Brand Metribuzin 4SC tank 
mixes with sulfonylurea herbicides (Ally, Amber, Finesse, Glean FC and Harmony Extra). Additional 
pesticides may also be tank mixed with Omni Brand Metribuzin 4SC unless specifically prohibited on the 
mix products’ label. In some instances, combinations with organophosphate insecticides may cause 
temporary leaf yellowing and/or crop injury, especially when widely fluctuating day/night temperatures 
occur near application. 
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. 
Read and follow the applicable restrictions and limitations and directions for use on all product labels 
involved in tank mixing. Users must follow the most restrictive use directions for use and precautionary 
statements of each product in the tank mixture.

FIELD CORN 
Application: Apply Omni Brand Metribuzin 4SC 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. 
Post-emergence Applications: Omni Brand Metribuzin 4SC is recommended for control of selected 
broadleaf weeds when applied as a tank mix combination with certain broadleaf herbicides presently 
registered and recommended for post-emergence use in field corn. Herbicides which may be tank mixed 
with Tribute SC include: 2, 4-D, Atrazine, Banvel, Basagran, Buctril/Buctril Gel, Buctril+atrazine (Premix), 
Clarity, Laddock S-12, Marksman, Pursuit*, Resource, Scorpion III and Tough. 
 
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. 
Read and follow the applicable restrictions and limitations and directions for use on all product labels 
involved in tank mixing. Users must follow the most restrictive use directions for use and precautionary 
statements of each product in the tank mixture 
 
* Use only on Pursuit resistant/tolerant corn hybrids (IMI-corn). 
POST-EMERGENCE BROADCAST APPLICATION 
Ground Application: Adjust nozzle height above crop and weed canopy to ensure uniform spray 
coverage. Gallonage should be increased with increasing weed size and population density. 
For tank mixes of Omni Brand Metribuzin 4SC plus atrazine, Basagran, Laddok S-12, Buctril, Buctril + 
atrazine, Pursuit, Resource, Tough, or 2,4-D amine formulations, use flat nozzles spaced a maximum of 
20 inches apart. Best results are achieved using a minimum of spray volume of 10 gallons per acre and 
spray pressure from 20 to 24 psi. 
 
For Omni Brand Metribuzin 4SC tank mixes with Banvel, Clarity, Marksman, 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 using a minimum spray volume of 20 gallons per acre and keeping spray 
pressures at or below 20 psi unless otherwise specified by the nozzle manufacturer. 
 
For further precautions, restrictions and additional instructions and recommendations, consult the tank 
mix partner’s label. 
Aerial Application: Apply in a minimum spray volume of 3 gallons per acre. For optimum spray coverage 
and distribution, use a minimum of 5 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 toward 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, restrictions and recommendations. 
POST DIRECTED APPLICATION 
Omni Brand Metribuzin 4SC in tank mix combinations with Banvel, 2,4-D, Buctril or Scorpion III 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

26
Filename:OmniBrandMetribuzin4SC(5905ͲARE)022218CLN
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, restrictions and additional recommendations, 
refer to the appropriate tank mix partner’s label. 
ADJUVANTS 
The adjuvant types listed below may be utilized with certain Omni Brand Metribuzin 4SC tank mix 
combinations. 
Consult the tank mix recommendations section for the appropriate adjuvant and rate. Use of non-
recommended adjuvant or rates may result in severe leaf burn, crop stunting, and/or stand reduction. 
Use only adjuvants which are exempt from tolerance requirements under 40 CFR 180.1001. 
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 
Omni Brand Metribuzin 4SC tank mixtures as severe leave burn, crop stunting, and/or stand reduction 
may occur. 
RAINFASTNESS 
Omni Brand Metribuzin 4SC will not reduce rainfastness of the recommended 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 Omni Brand Metribuzin 
4SC label for specific instructions on cleaning spray equipment. Special attention should be given to the 
required cleanup procedures for 2,4-D, Banvel, Clarity, and Marksman. 
STRESS
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. 
RESTRICTIONS FOR USE ON FIELD CORN: 
x Do not use on corn grown for seed, sweet corn, popcorn, or white corn. 
x Do not apply more than 0.25 pound a.i. METRIBU ZIN (5-1/3 ounces Omni Brand Metribuzin 4SC) 
per acre per use season. 
x Do not apply when field corn is under stress (see Stress statement above). 
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 Washin gton, Oregon or Idaho or crop injury may occur. 
x Observe all precautions and limitations on labeling of all products used in the tank mixtures. 
x Feeding Restrictions: Do not graze filed corn treated with Omni Brand Metribuzin 4SC within 60 
days of last application.

inch of irrigation within one month after application of Omni Brand Metribuzin 4SC or crop injury 
may occur. 
x Maintain continuous spray tank agitation to keep material in suspension. Avoid overlapping of 
spray swaths and shut off spray booms while turning, slowing or stopping, or crop injury will 
occur. 
NOTE: This treatment may cause some chlorosis or minor necrosis. Because garbanzo bean varieties 
may vary in their susceptibility to Omni Brand Metribuzin 4SC, determine crop tolerance prior to adoption 
as a field scale practice to prevent possible injury. 
RESTRICTIONS FOR USE ON GARBANZO BEANS: 
x Do not use on clay knobs or poorly covered subsoils. 
x Do not apply preemergence on shallow seedings less than 2 inches deep.

application. 
GARBANZO BEANS 
Application Pints Omni Brand Metribuzin 4SC/Acre 
Broadcast Preemergence 1/2 - 3/4 
Apply specified dosage in a single preemergence application using 10 to 40 gallons of water per acre 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 Omni Brand Metribuzin 4SC into the top 1 to 2 inches of soil with spike harrows, 
or similar shallow incorporation equipment, then cross harrow to insure 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. 
Weeds Suppressed* with Omni Brand Metribuzin 4SC herbicide: 
WEEDS SUPPRESSED 
Chickweed, Common Lambsquarters, Common 
Dog Fennel (Mayweed) Pigweed, Redroot 
Field Pennycress Shepherdspurse

* Suppression is a reduction in weed size and growth compared to non-treated area in the same field. 
Omni Brand Metribuzin 4SC used alone will not control triazine-resistant weed species. 
LENTILS AND PEAS 
Area of use: Idaho, Oregon, Washington, Montana, and North Dakota 
Application: Use Omni Brand Metribuzin 4SC as a preemergence and postemergence application for 
the suppression of certain broadleaf weeds in lentils and peas. 
SPECIAL PRECAUTIONS FOR USE ON LENTILS AND PEAS - All Applications: 
x Crop injury may result if crop is under stress conditions caused by cold weather, low fertility, 
disease or insect damage. 
x Crop injury may also result if application is followed by heavy rain. 
x 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 will occur. 
NOTE: This treatment may cause some chlorosis or minor necrosis. Because lentil and pea varieties may 
vary in their susceptibility to Omni Brand Metribuzin 4SC, determining crop tolerance prior to adoption as 
a field scale practice is suggested to prevent possible injury. 
RESTRICTIONS FOR USE ON LENTILS AND PEAS - All Applications:

POTATOES
Omni Brand Metribuzin 4SC 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 Omni Brand Metribuzin 4SC4. 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. 
Application: Ground Application: Omni Brand Metribuzin 4SC is recommended for use 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 spray at 20 or more gallons per 
acre. 
Aerial Application: Omni Brand Metribuzin 4SC may be applied in aerial spray equipment as a 
preemergence and/or postemergence application at 5 or more gallons per acre. 
Chemigation: Omni Brand Metribuzin 4SC may be applied preemergence and/or early postemergence to 
potatoes using center pivot, solid set and lateral roll systems. Apply specified dosage in 1/4 to 3/4 inch of 
water per acre (1/4 to 1/2 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 Omni Brand Metribuzin 4SC has 
been flushed from the lines before shutting down the system. 
 
SPECIAL PRECAUTIONS FOR USE ON POTATOES: 
x 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.

SOYBEANS (EXCEPT IN CALIFORNIA) 
Application: Omni Brand Metribuzin 4SC tank mix combinations can be used for preplant incorporated 
applications, pre-emergence surface applications, split-shot application and extended split-shot 
application. Omni Brand Metribuzin 4SC can also be used as an over lay application following a preplant 
incorporated application of a recommended grass herbicide and alone as a pre-emergence surface 
application. All these applications can be applied with ground equipment, and some can be applied with 
aerial spray equipment. In addition, Omni Brand Metribuzin 4SC can be applied as a post-emergence 
directed spray to soybeans in AL, AR, FL, GA, KY, LA, MS, MO, NC, OK, SC, TN, and TX. 
Activation: A minimum amount of moisture is required to activate Omni Brand Metribuzin 4SC. In areas 
of low rainfall, pre-emergence applications to dry soil should be followed with light irrigation of 1/4 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 change 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 in organic matter.

If needed, application of Omni Brand Metribuzin 4SC alone or in a registered tank mix according to 
labeled directions on this label, may be followed by an early post-emergence application of Scepter 
herbicide for control of cocklebur. 
 
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read 
and follow the applicable restrictions and limitations and directions for use on all product labels involved in 
tank mixing. Users must follow the most restrictive directions for use and precautionary statements of 
each product in the tank mixture. 
 
When preparing the spray mixture with Scepter, add 2 pints of non-ionic surfactant approved for use on 
growing crops and containing at least 80% active ingredient per 100 gallons of mixture. Apply crop oil 
concentrate (COC) at the rate specified on the COC label. 
 
Use Scepter only in the states where it is registered as listed on the product label. 
 
Pre-harvest Interval (PHI): Apply Scepter at least 90 days before harvest of soybeans. Do not graze or 
feed soybean forage, hay, or straw to livestock. 
 
Refer to the Scepter label for additional cautions and precautions, directions, limitations, and information 
on environmental hazards and planting of rotational crops. 
SOYBEANS: SPLIT-SHOT APPLICATION 
A preplant incorporated application of Omni Brand Metribuzin 4SC tank mixed with either Treflan, Lasso, 
Dual, Prowl or Sonalan and followed by a pre-emergence surface application of Omni Brand Metribuzin 
4SC alone after planting but prior to soybean emergence, will control more broadleaf and grass weeds in 
soybeans than when either herbicide is used alone. 
 
Refer to the Treflan, Lasso, Dual, Prowl or Sonalan labels, and to appropriate sections of this label for 
directions on soil preparation, herbicide application, incorporation techniques, herbicide rates, weed 
species controlled, and restrictions for using tank mix combinations of Omni Brand Metribuzin 4SC. 
Carefully observe the “Special Precautions” section concerning the use of Omni Brand Metribuzin 4SC in 
tank mix combinations on soybeans. 
 
When a Split-Shot application of Omni Brand Metribuzin 4SC with Prowl, Treflan, or Sonalan is used, the 
preplant incorporated tank mix may be applied up to 21 days prior to planting soybeans; with Dual or 
Lasso, the preplant incorporated tank mix may be applied up 14 days prior to planting. 
 
On medium and fine textured soils with greater than 2% organic matter, a rate range is specified for the 
Omni Brand Metribuzin 4SC pre-emergence overlay application. The higher rate should be used (a) in 
fields with a history of severe broadleaf weed pressure, (b) when the time between preplant incorporated 
tank mix and pre-emergence overlay applications approaches the maximum stated above, and/or (c) 
when the organic matter content of the soil is at the upper end of the indicated range. 
 
For black nightshade control, refer to the appropriate sections of the Lasso, Dual, or Sonalan labels for 
specific instructions. 
SOYBEANS: 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 Omni Brand Metribuzin 4SC 
tank mixed with either Dual or Lasso, followed by a pre-emergence surface application of Omni Brand 
Metribuzin 4SC tank mixed with Dual or Lasso after planting but prior to soybean emergence, will control 
more broadleaf and grass weeds in soybeans than either herbicide alone.

43
Filename:OmniBrandMetribuzin4SC(5905ͲARE)022218CLN
 
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 Omni Brand Metribuzin 4SC with Dual or Lasso 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, the higher rates should be used (a) in fields with a history of severe weed 
pressure, (b) when the time between early preplant tank mix and pre-emergence overlay applications 
approaches 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 (e) when the 
early preplant tank mix application is shallow incorporated. 
 
When weeds exceed 1 to 1-1/2 inches in height or diameter at application, use a contact herbicide, such 
as glyphosate or Gramoxone. Refer to the Dual or Lasso label, and to appropriate sections of this label 
for additional information on soil preparation, herbicide application, weeds controlled, precautions, 
restrictions, limitations and sprayer clean-up.

Apply Omni Brand Metribuzin 4SC plus Treflan to the soil surface and incorporate in the same operation, 
if possible. 
Variable weed control may result from delayed incorporation if Omni Brand Metribuzin 4SC plus Treflan 
are applied to a wet, warm soil surface or if the wind velocity is 10 miles per hour or higher. Use 
machinery that mixes Omni Brand Metribuzin 4SC plus Treflan thoroughly with the soil. Incorporation may 
be delayed up to 24 hours after application. 
Shallow incorporation with implements set to cut less than 2 inches deep may result in erratic weed 
control. Do not use spike or spring-tooth harrows alone for incorporation. 
 
Incorporation Equipment: 
1. Set PTO-driven equipment (tillers, cultivators, hoes) to cut 2 to 3 inches deep and space rotors to 
provide a clean sweep of the soil. PTO equipment should not be operated at a speed greater than 
4 miles per hours. 
2. Set disk to cut 4 to 6 inches deep and operate twice in different directions at 4 to 6 miles per 
hours.
