WEED RESISTANCE MANAGEMENT 
AUTHORITY 4F which contains the active ingredient Sulfentrazone is a group 14 herbicide based on the mode of action classification 
system of the Weed Science Society of America. 
Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one or mor e 
herbicides is a best practice. A diversified weed management program may include the use of multiple herbicides with different sites 
of action and overlapping weed spectrum with or without tillage operations and/or other cultural practices. Research has demonstrated 
that using the labeled rate and directions for use is important to delay the selection for resistance. 
The continued effectiveness of this product depends on the successful implementation of a weed resistance management program. 
To aid in the prevention of developing weeds resistant to this product, users should: 
 · Scout fields before application for weeds for identification of species and sizes. 
 · Start with a clean field, using either a burndown herbicide application or tillage. 
 · Control weeds early when they are relatively small (less than 4 inches). 
 · Apply full labeled rates of AUTHORITY 4F for the most difficult to control weed in the field at the specified time (correct weed size) 
to minimize weed escapes. 
 · Scout fields after application to detect any poor performance or likely resistance in weeds. 
 · Control weed escapes before they reproduce by seed or proliferate vegetatively. 
 · Report any incidence of non-performance of this product against a particular weed to your local retailer or county extension agent. 
 · Contact your crop advisor or extension agent to find out if suspected resistant weeds to these MOAs have been found in your 
region. Do not assume that each listed weed is being controlled by multiple sites of action. Products with multiple active ingredients 
are intended to broaden the spectrum of weeds that are controlled. Some weeds may be controlled by only one of the active 
ingredient in this product. 
 · If resistance is suspected, treat weed escapes with an herbicide having a site of action other than 14 and/or use nonchemical 
methods to remove escapes, as practical, with the goal of preventing further seed production. 
 · Suspected herbicide-resistant weeds may be identified by these indicators: 
 · Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved 
on adjacent weeds; 
 · A spreading patch of non-controlled plants of a particular weed species; and 
 · Surviving plants mixed with controlled individuals of the same species. 
Additionally, users should follow as many of the following herbicide resistance management practices as is practical: 
 · Use a broad spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program. 
 · Utilize sequential applications of herbicides with alternative sites of action. 
 · Rotate the use of this product with non-Group 14 herbicides. 
 · Avoid making more than two applications of AUTHORITY 4F and any other Group 14 herbicides within a single growing season 
unless mixed with an herbicide with a different site of action with an overlapping spectrum for the difficult-to-control weeds. 
 · Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover crops and weed-free crop 
seeds, as part of an integrated weed control program. 
 · Use good agronomic principles that enhance crop development and crop competitiveness. 
 · Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds. 
 · Manage weeds in and around fields, during and after harvest to reduce weed seed production. 
 
PRODUCT INFORMATION 
AUTHORITY 4F is a selective soil-applied herbicide for the control of susceptible broadleaf, grass and sedge weeds. AUTHORITY 
4F is formulated as a 4 pounds per gallon flowable containing the active ingredient, sulfentrazone. If adequate moisture (1/2" to 1") 
from rainfall or irrigation is not received within 7 to 10 days after the AUTHORITY 4F treatment, a shallow incorporation may 
be needed to obtain desired weed control. When activating moisture is received after dry conditions, AUTHORITY 4F will provide 
a reduced level of control of susceptible germinating weeds. Soil applications of AUTHORITY 4F must be made before crop seed 
germination to prevent injury to the emerging crop seedlings. When applications after planting are delayed, injury may occur if seeds 
are germinating or if they are located near the soil surface. 
 
It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must 
follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. 
 
 
APPLICATION INSTRUCTIONS 
AUTHORITY 4F may be applied to soil as a preplant incorporated treatment or as a pre-emergence (prior to weed and/or crop 
emergence) surface application. Additional application methods include post-plant treatments, over-the-top and layby, in variou s 
crops. Application methods are defined in the following Crop Use Directions sections. 
 
Preplant incorporated treatments require a uniform surface application followed by incorporation. Do not incorporate to a depth greater 
than 2 inches which may result in poor weed control. Care must be taken not to create overlaps in treated zones due to soil movement, 
which will result in excessive AUTHORITY 4F rates that could result in adverse crop response.

Page 4 
All soil applications and the residual activity of post-plant applications of AUTHORITY 4F require adequate moisture for herbic idal 
activation. The ultimate amount of moisture, whether supplied by rainfall or irrigation, is dependent on several factors. These factors 
include but are not limited to existing soil moisture at application, soil type, organic matter and tilth. In crop situations d ependent on 
rainfall, AUTHORITY 4F can await activating moisture for extended periods (10 to 14 days or longer) depending on the soil parameters 
described above. Once activated, AUTHORITY 4F will provide activity on existing weeds. The level of activity will depend on the weed 
species and their size at time of activation. Where irrigation is not available and rainfall has not provided activation, parti cularly for 
surface applications of AUTHORITY 4F, a shallow incorporation is recommended for destruction of any germinating weeds and to 
incorporate AUTHORITY 4F. Herbicide incorporation will initiate the process of activation with existing soil moisture. In circumstances 
where prolonged periods without rainfall and/or irrigation is not possible, alternative or additional weed management practices 
(cultivation or post-applied herbicides) may be required. 
 
Extreme care must be exercised and the Crop Specific Use Directions followed exactly in crops allowing post plant applications of 
AUTHORITY 4F. Over-the-top and lay-by applications will provide contact and residual weed control, depending on species. The 
addition of surfactants may increase contact weed control performance but may also increase the risk of adverse crop response a s 
well. 
 
AUTHORITY 4F HERBICIDE PRODUCT USE RATES 
The following directions for the selection of AUTHORITY 4F application rates are critical to achieve maximum performance and to 
ensure maximum crop safety. The user is required to read and follow the specific AUTHORITY 4F use directions and restrictions for 
each crop as defined in subsequent sections of this label. The user is cautioned that some crops respond differently to AUTHORITY 
4F. This response is governed by the AUTHORITY 4F application rate, various soil factors and inherent crop sensitivity. The Cr op 
Specific Use Directions have been designed to minimize the risk of adverse crop response while maintaining optimum weed control. 
 
Mode of Action 
Sulfentrazone, the active ingredient in AUTHORITY 4F, is a potent inhibitor of the enzyme Protoporpyrinogen Oxidase IX (PPO IX) 
required for the formation of chlorophyll. Inhibition of PPO IX enzyme results in the liberation of singlet oxygen (O) that, in turn, disrupts 
cellular membranes and causes cellular leakage. The ultimate manifestation of the process is cellular death leading to plant d eath. 
The selective herbicidal activity of sulfentrazone is based on its greater affinity for the PPO IX enzyme in weed species versu s crop 
plants. 
 
Mechanism of Action 
Following the application of AUTHORITY 4F to soil, germinating seeds and seedlings take up sulfentrazone from the soil solution . 
The amount of sulfentrazone in soil solution, and available for weed uptake, is determined primarily by soil type, organic matt er and 
soil pH. Sulfentrazone adsorbs to the clay and organic matter (OM) fractions of soils; effectively limiting the amount of active ingredient 
immediately available to control weeds. Soils typically increase in clay content through the series from coarse to fine as noted in the 
following Soil Classification Chart.

Influence of Soil type, organic matter and pH on AUTHORITY 4F Use Rates and Crop Response 
Soil organic matter content can vary widely and independently of soil type and requires an accurate analysis of representative soil 
samples to determine its content. 
 
Soil pH also exerts a dramatic effect on sulfentrazone availability in the soil solution. As soil pH increases, sulfentrazone a vailability 
increases. Accurate soil pH information will require an accurate analysis of representative soil samples. 
 
The total amount of sulfentrazone available in solution, in any given soil, is determined by the interaction of soil type (clay content), % 
organic matter and pH. The application timing (relative to the emergence of the crop and weeds) and amount of rainfall and/or 
irrigation received will ultimately determine, in conjunction with the soil parameters and pH, the amount of sulfentrazone in soil solution. 
It is important to note that AUTHORITY 4F can await activating moisture. However, diminished weed 
control may result due to the successive increase in weed growth versus timing of activation. 
 
It is important to note that irrigation with highly alkaline water (high pH) following a AUTHORITY 4F soil application can also significantly 
increase the amount of sulfentrazone available in the soil solution. Irrigation with water having a pH greater than 7.5 could r esult in 
adverse crop response. This response will ultimately depend on initial AUTHORITY 4F application rate, timing, amount and pH of 
irrigation water and sensitivity of the crop and its growth stage when irrigated. The risk of adverse crop response will lessen with the 
advance in growth stage among most crops. 
 
The following Crop Specific Use Directions have been designed with specific AUTHORITY 4F recommendations for each crop based 
on the soil type, soil organic matter, and soil pH interactions described above. The user is cautioned that crop tolerance and weed 
control performance are based on strict adherence to these recommendations.

MANDATORY SPRAY DRIFT 
Ground Application 
Utilize a boom and nozzle sprayer equipped with the appropriate nozzles, spray tips and screens and adjusted to provide optimum 
spray distribution and coverage at the appropriate operating pressures. Select nozzles and application pressure that deliver medium 
to coarse or larger spray droplets as indicated in the nozzle manufacturer’s recommendations and in accordance with ASABE 
Standard S-572. Select coarse to very coarse droplet size when used as a preemergent/preplant application. Select medium to very 
coarse droplet size when used postemergence with a contact burndown herbicide. Do not apply as spray droplets smaller than medium 
to coarse (defined by the ASABE standard). Apply a minimum of 10 gallons of finished spray per acre by ground. When mixed with 
a contact burndown herbicide, ground applicators must use a minimum spray volume of 15 gallons per acre. Be aware that overlaps 
and slower ground speeds while starting, stopping or turning while spraying may result in excessive application and subsequent crop 
response. Do not apply when wind speed favors drift beyond the area intended for treatment. Applicators may spray only when wind 
speed is between 3 and 10 mph. 
 
Ground applications should not be made at a height greater than 30 inches from the soil. 
 
Aerial Application 
Aerial application is allowed only when environmental conditions prohibit ground application. When this product is allowed to be 
applied by air, applicator must use a minimum finished spray volume of 5 gallons per acre. The maximum release height must be 10 
feet from the top of the canopy, unless a greater application height is required for pilot safety. Select nozzles and application pressure 
that deliver medium to coarse or larger spray droplets as indicated in the nozzle manufacturer’s recommendations and in accordance 
with ASABE Standard S-572. Select coarse to very coarse droplet size when used as a preemergent/preplant application. Select 
medium to very coarse droplet size when used postemergence with a contact burndown herbicide. Do not apply as spray droplets 
smaller than medium to coarse (defined by the ASABE standard). 
 
Do not apply when wind speed favors drift beyond the area intended for treatment. Applicators may spray only when wind speed is 
between 3 and 10 mph. 
 
These requirements must be followed to avoid off-target movement from aerial applications. These requirements do not apply to 
forestry applications, public health uses or to applications of dry materials. 
1. The distance of the outermost 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. Observe the regulations of the State where applications are made. 
4. Applicators must observe and abide by the requirements of the Aerial Drift Reduction Advisory. 
 
 
SPRAY DRIFT REDUCTION ADVISORIES 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMETAL CONDITONS. 
 
 
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 for pesticide performance. Applying larger droplets reduces drift potential but will not 
prevent drift if applications are made improperly or under unfavorable environmental conditions. (See information on Wind, 
Temperature and Humidity, and Temperature Inversions in subsequent sections). 
 
 
Controlling Spray Droplet Size 
Volume – Use high flow rate nozzles to apply the greatest practical spray volume. Nozzles with higher rated flow generally produce 
larger droplets. 
 
Pressure - When higher flow rates are needed, use higher flow rate nozzles rather than increasing spray pressure. 
 
Do not exceed the nozzle manufacturer’s recommended pressures. Lower pressure produces larger droplets in many types of 
nozzles. 
 
Number of Nozzles – Use the minimum number of nozzles that provide uniform coverage. 
 
Nozzle Orientation – For aerial application, the required practice is to orient nozzles so that the spray is released parallel to the 
airstream. This orientation usually produces larger droplets as compared to other nozzle orientations. Significant nozzle defl ection 
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 for both ground and aerial applications. Solid stream nozzles oriented straight back 
usually produce the largest droplets and the lowest drift potential in aerial applications 
 
Boom Length – For some aerial 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 - Making applications at the lowest height that is safe reduces exposure of droplets to evaporation and wind. 
 
Swath Adjustment – When aerial applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the 
upwind and downwind edges of the field, the applicator must compensat e for this displacement by the path of the aircraft upwind . 
Swath adjustment or offset distance should increase when conditions favor increased drift potential (higher winds, smaller drop lets, 
etc).

Page 6 
Wind – Drift potential is lowest between wind speeds of 3-10 mph. However, many factors, including droplet size and equipment type 
determine drift potential at any given wind speed. Application should be avoided below 3 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 may potentially 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 low speed and variable winds common during inversions. Temperature inversions are 
characterized by increasing temperatures with altitude and are common during conditions of limited cloud cover and little to no wind. 
They often begin to form as the sun sets and may often continue into the morning. The presence of a temperature inversion may be 
indicated by ground fog. However if fog is not present, the movement of smoke from a ground source or an aircraft smoke generator 
can also identify inversions. Smoke that remains in layers and moves laterally in a concentrated cloud (under low speed wind 
conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. 
 
Sensitive Areas – The pesticide should only be applied when the wind is blowing away from sensitive areas (e.g. residential areas, 
bodies of water, known habitat for threatened or endangered species, non-target crops). 
 
Off-Target Movement of AUTHORITY 4F 
Drift of dilute spray mixtures containing AUTHORITY 4F must be prevented. Observation of the preceding environmental conditions, 
correct application equipment design, calibration and application practices will significantly diminish the risk of off-target spray drift. 
AUTHORITY 4F can cause significant symptomology by drift on to sensitive crops and other plants. This symptomology may manifest 
initially as discreet, localized spots where contacted by AUTHORITY 4F drift mixtures. Depending on concentration of the spray 
solution and droplets size (effectively determining the dosage of sulfentrazone) and also depending on the inherent sensitivity of the 
plants involved, these spots or lesions may or may not coalesce. These effects will usually not have lasting effects on plant growth, 
but will likely reduce the value of affected fruit or foliage where grade or quality is associated with appearance. In severe drift instances 
with particularly sensitive crops, defoliation of affected foliage could result. Failure to follow these guidelines and environ mental 
prohibitions that then result in off-target movement or drift of AUTHORITY 4F on to unintended crops or plants, irrespective of severity, 
constitutes misapplication of this product. FMC accepts no responsibility or liability for potential crop effects that may result from such 
misapplication of AUTHORITY 4F. 
 
Chemigation Application 
AUTHORITY 4F may be applied through sprinkler irrigation systems including center pivot, lateral move, end tow, solid set, or h and 
move irrigation systems. Do not apply this product through any other type of irrigation system. Do not connect any irrigation system 
(including greenhouse systems) used for pesticide application to a public water system. Crop injury, lack of effectiveness or illegal 
residues on or in the crop can result from non-uniform distribution of treated water. If you have questions about calibration, you should 
contact State Extension Service specialists, equipment manufacturers, or other experts. 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 ma ke 
necessary adjustments should the need arise. 
 
It is important to note that irrigation with highly alkaline water (high pH) following a AUTHORITY 4F soil application can also significantly 
increase the amount of sulfentrazone available in soil solution. Irrigation with water having a pH greater than 7.5 could result in adverse 
crop response. This response will ultimately depend on initial AUTHORITY 4F application rate, application timing, amount and pH of 
the irrigation water, and the sensitivity of the crop and the growth stage when irrigated. The risk of adverse crop response will lessen 
with advancing growth stages of most crops. 
 
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 also 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 automatica lly 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. 
 
AUTHORITY 4F should be metered into the irrigation system continuously for the duration of the water application. AUTHORITY 4F 
should be diluted in sufficient volume to ensure accurate application over the area to be treated. Use the appropriate amount of water 
to carry the product to the soil surface. Continuous agitation is required to maintain product suspension in the solution tank. A jar test 
should be conducted to ensure that phase separation would not occur during dilution and application. Failure to achieve a unif orm 
dilution throughout the time of application may result in undesirable residues or less than desirable weed control. Flush the lines at 
the completion of the application and then turn the water off promptly. 
 
When using water from public water systems; DO NOT APPLY AUTHORITY 4F THROUGH ANY IRRIGATION SYSTEM 
PHYSICALLY CONNECTED TO A PUBLIC WATER SYSTEM. Public water system means a system for the provision to the public 
of piped water for human consumption if such system has at least 15 service connections or regularly serves an average of at le ast 
25 individuals daily at least 60 days of the year. AUTHORITY 4F may be applied through irrigation systems, which may be supplied 
by a public water system only if water from the water system is discharged into a reservoir tank prior to pesticide introduction. There 
shall be a complete physical break (air gap) between the outlet end of the fill pipe and to top or overflow rim of the reservoir tank of at 
least twice the inside diameter of the fill pipe. Before beginning chemigation, always make sure that the air gap exists and that there

Application with Dry Fertilizers 
 AUTHORITY 4F may be applied impregnated on dry fertilizers. When applied as directed with adequate soil coverage, AUTHORITY 
4F dry bulk fertilizer mixtures will provide satisfactory weed control. 
 
Follow all AUTHORITY 4F label directions regarding product use rates per acre, registered crops, incorporation, special instructions 
and precautions. 
 
Apply AUTHORITY 4F /dry fertilizer mixtures with ground equipment only. 
 
 
All individual state regulations relating to dry bulk fertilizer blending, registration, labeling, and application are the responsibility of the 
individual and/or company preparing, storing, transporting, selling or applying the AUTHORITY 4F/dry fertilizer mixture. 
 
Impregnation Directions
 
To impregnate AUTHORITY 4F on dry bulk fertilizer, use a closed rotary-drum mixer or other commonly used dry bulk fertilizer blender 
equipped with suitable spray equipment. 
 
Prepare a slurry of AUTHORITY 4F in a clean container using clear water. Slowly add the AUTHORITY 4F/water slurry to the 
impregnation spray tank and finish filling as needed with clear water. Spray nozzles must be placed to provide uniform coverage of 
AUTHORITY 4F onto the fertilizer during mixing. 
 
Refer to the SPRAYER EQUIPMENT CLEAN-OUT section for directions for cleaning impregnation equipment, transport equipment, 
loading equipment and application equipment. 
 
Apply the AUTHORITY 4F dry bulk fertilizer with an accurately calibrated dry fertilizer spreader. The AUTHORITY 4F dry bulk fertilizer 
mixture must be spread uniformly on the soil surface. Uneven spreading leaving untreated areas can cause poor weed control or 
overlapping areas with potential increased AUTHORITY 4F use rates could result in possible crop response. 
 
A minimum of 200 pounds of dry bulk fertilizer impregnated with the listed amount of AUTHORITY 4F must be applied per acre to 
achieve adequate soil coverage for satisfactory weed control. 
 
DO NOT impregnate AUTHORITY 4F onto coat ed ammonium nitrate or limestone becaus e these materials will not absorb the 
herbicide. 
 
Refer to the appropriate crop section of the AUTHORITY 4F label to determine the rate of AUTHORITY 4F to be applied per acre. 
Use the following table to determine the amount of AUTHORITY 4F to be impregnated on a ton (2000 pounds) of dry bulk fertilizer 
based on the rate of fertilizer that will be applied per acre. 
 
For those rates not listed in the following table, calculate the amount of AUTHORITY 4F to be impregnated on a ton of dry bulk fertilizer 
using the following formula:

Application with Liquid Fertilizer 
AUTHORITY 4F may be applied using liquid fertilizer solutions as the carrier. The fertilizer solutions may either be concentra te 
formulations as blended or diluted with water. When applied as directed with adequate soil coverage, AUTHORITY 4F applied with 
liquid fertilizer mixtures will provide satisfactory weed control. However, adequate soil coverage is essential to achieve acc eptable 
levels of weed control. 
 
Herbicide mixing, solution stability and/or compatibility problems can occur when liquid fertilizers are used as a carrier. Compatibility 
tests must be conducted prior to mixing to insure tank mixture compatibility and stability. The use of compatibility agents ma y be 
beneficial to achieve and maintain a homogenous solution. 
 
Mixing Instructions for Liquid Fertilizer Applications 
Fill the clean spray tank to one half of the total volume with the fertilizer solution. Start the spray tank agitation system. Prepare a 
slurry of AUTHORITY 4F in a clean container with clean water using equal volumes of AUTHORITY 4F and clean water. Slowly add 
the AUTHORITY 4F/water slurry to the spray tank. Carefully rinse the slurry container, adding the rinsate to the spray tank. Better 
mixing of the AUTHORITY 4F/water slurry may be achieved if the slurry is added using induction systems on the sprayer fill plumbing 
system. 
 
Complete filling the spray tank to the desired level. Sufficient and continuous spray tank agitation is required at all times to maintain 
a homogenous spray solution. The spray system must be designed such that there is sufficient flow capacity to uniformly apply t he

Page 8 
spray mixture and maintain adequate tank agitation. Some systems may require separate pumps to simultaneously supply the spray 
system and the spray tank agitation system. Ensure the AUTHORITY 4F slurry is thoroughly mixed before application. 
 
For tank mixtures with other herbicide(s), a compatibility test must be conducted to ensure product compatibility before mixing . It is 
the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Use rs must 
follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. 
 
Apply the AUTHORITY 4F spray mixture immediately after mixing. Do not store the sprayer overnight or for any extended period of 
time with the AUTHORITY 4F spray mixture remaining in the tank. 
 
 
Do not premix AUTHORITY 4F spray solutions in nurse tanks. 
 
Follow all AUTHORITY 4F label directions regarding product use rates per acre, registered crops, application instructions, 
incorporation directions, special instructions and all precautions. 
 
All individual state regulations relating to liquid fertilizer blending, storage, transportation, registration, labeling, and application are the 
responsibility of the individual and/or company preparing, selling or applying the AUTHORITY 4F and fertilizer mixture.

MIXING AND LOADING INSTRUCTIONS 
AUTHORITY 4F may be applied alone, or in tank mixtures with other herbicides for the control of additional weed species. Mixtur es 
with some other pesticides have not been tested. Conduct appropriate compatibility tests prior to tank mixing with other pestic ides. 
Follow all precautions and restrictions on the tank mix partner label. 
 
It is important that spray equipment is clean and free of existing pesticide residues before preparing AUTHORITY 4F spray mixtures. 
Follow the spray tank clean out procedures specified on the label of the product or products previously applied. 
 
For best results fill spray tank with one half of the volume of clean water needed for the field to be treated. Start agitation system. 
Prepare a slurry of AUTHORITY 4F in a clean container using clean water. Slowly add the AUTHORITY 4F/water slurry to the spray 
tank. Carefully rinse the slurry container, adding the rinsate to the spray tank. Complete filling the spray tank to the des ired level. 
Continuous spray tank agitation is required at all times to maintain a uniform spray solution. Make sure AUTHORITY 4F is thoroughly 
mixed before application or before adding another product to the spray tank. 
 
Use the AUTHORITY 4F spray mixture immediately after mixing. Do not store the sprayer overnight or for any extended period of time 
with the AUTHORITY 4F spray mixture remaining in the tank. 
 
Do not premix AUTHORITY 4F spray solutions in nurse tanks. 
 
If AUTHORITY 4F is tank mixed with other herbicides, all additional directions, restrictions and precautions for the tank mixtu re 
herbicides must be followed. 
 
Proper handling instructions: AUTHORITY 4F may not be mixed or loaded within 50 feet of any wells (including abandoned wells 
and drainage wells), sinkholes, perennial or intermittent streams and rivers, and natural or impounded lakes and reservoirs. Th is 
setback does not apply to properly capped or plugged abandoned wells and does not apply to impervious pads or properly diked 
mixing/loading areas. 
 
Operations that involve mixing, loading, rinsing, or washing of this product into or from pesticide handling or application equipment or 
containers within 50 feet of any well are prohibited unless conducted on an impervious pad constructed to withstand the weight of the 
heaviest load that may be positioned on or moved across the pad. Such a pad shall be designed and maintained to contain any 
product spills or equipment leaks, container or equipment rinse or wash water, and rainwater that may fall on the pad. Surface water 
shall not be allowed to either flow over or from the pad, which means the pad must be self-contained. The pad shall be sloped t o 
facilitate material removal. An unroofed pad shall be of sufficient capacity to contain at a minimum 110% of the capacity of the largest 
pesticide container or application equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclu de 
precipitation from contact with the pad shall have a minimum co ntainment capacity of 100% of the capacity of the largest pestic ide 
container or application equipment on the pad. Containment capacities as described above shall be maintained at all times. The above 
specific minimum containment capacities do not apply to vehicles when delivering pesticide shipments to the mixing/loading site . 
States may have in effect additional requirements regarding wellhead setbacks and operational containment. 
Product must be used in a manner that will prevent back siphoning in wells, spills or improper disposal of excess pesticide, sp ray 
mixtures or rinsates.
 
 
SPRAYER EQUIPMENT CLEAN-OUT 
As soon as possible after spraying AUTHORITY 4F and before using sprayer equipment for any other applications, the 
sprayer must be thoroughly cleaned to avoid potential crop effects using the following procedure. Residues left in mixing 
equipment, spray tanks, hoses, spray booms and nozzles can cause crop effects if they are not properly cleaned. In addition, 
users must take appropriate steps to ensure proper equipment clean-out for any other products mixed with AUTHORITY 4F 
as required on the other product labels. More complete cleaning can be achieved if the spray system is cleaned immediately 
following the application. 
 
1. Drain sprayer tank, hoses, spray boom and spray nozzles. Use a high-pressure detergent wash to remove physical sediment and 
residues from the inside of the sprayer tank and thoroughly rinse. Then, thoroughly flush sprayer hoses, spray boom and spray 
nozzles with a clean water rinse. Remove and clean spray tips and all filters and screens (tank, spray hose and spray tips) separately 
in the ammonia solution of Step 2.

Page 11 
2. Next, prepare a sprayer cleaning solution by adding three gallons of ammonia (containing at least 3% active) per 100 gallon s of 
clean water. Prepare sufficient cleaning solution to allow the operation of the spray system for a minimum of 15 minutes to thoroughly 
flush hoses, spray boom and spray nozzles. 
 
3. Convenient and thorough cleaning of the sprayer can be achieved if the ammonia solution or fresh water is left in the spray tank, 
hoses, spray booms and spray nozzles overnight or during storage. 
 
4. Before using the sprayer, completely drain the sprayer system. Rinse the tank with clean water and flush through the hoses, spray 
boom, and spray nozzles with clean water. Remove and clean spray tips and all filters and screens (tank, spray hose and spray tip) 
separately in an ammonia solution. 
 
5. Properly dispose of all cleaning solution and rinsate in accordance with Federal, State, and local regulations and guidelines. 
 
Do not apply sprayer cleaning solutions or rinsate to sensitive crops. 
 
Do not store the sprayer overnight or for any extended period of time with AUTHORITY 4F spray solution remaining in the tank, spray 
lines, spray boom plumbing, spray nozzles or strainers. 
 
If the sprayer has been stored or idle, purge the spray boom and nozzles with clean water before beginning any application. 
 
Should small quantities of AUTHORITY 4F remain in inadequately cleaned mixing, loading and/or spray equipment, they may be 
released during subsequent applications potentially causing effects to certain crops and other vegetation. FMC accepts no liability for 
any effects due to inadequately cleaned equipment. 
 
Do not drain or flush equipment on or near desirable trees or plants. 
 
Do not contaminate any body of water including irrigation water that may be used on other crops.

*Nutsedge Management 
AUTHORITY 4F Herbicide will aid in the management of yell ow and purple nutsedge populations by weakening existing nutsedge 
plants. The degree of suppression depends on the rate of AUTHORITY 4F Herbicide applied, moisture, soil conditions, the depth of 
nutsedge nutlets, weather, and the interval between AUTHORITY 4F Herbicide application and nutsedge emergence in the spring. 
 
Soil uptake is the major means of uptake by sedges however, postemergence applications to sedges allow AUTHORITY 4F Herbicide 
to be taken into the sedge through the foliage as well as soil uptake through the roots. Good spray coverage is required for optimum 
control of sedges especially when applying postemergence to the sedges. Use a quality federally approved nonionic surfactant (NIC) 
at the rate of 0.25% v/v when applying postemergence. Best suppressive activity is attained when nutsedge plants are small with 6 or 
fewer leaves. 
 
REPLANTING INSTRUCTIONS 
If initial planting of labeled crops fails to produce a stand, only labeled crops for AUTHORITY 4F or the tank mix partner; whichever is 
most restrictive, may be planted. Do not retreat field with AUTHORITY 4F or other herbicide containing sulfentrazone. Do not plant 
treated fields with any crop at intervals that are inconsistent with the Rotational Crop Guidelines on this label. When replan ting use 
minimum soil tillage to preserve the herbicide barrier and achieve maximum weed control.

AUTHORITY 4F may be applied in the fall following crop harvest or in existing fallow fields to control or suppress weeds the following 
season. The AUTHORITY 4F Rotational Crop Restrictions must be followed if crops are planted the next season. AUTHORITY 4F 
should be applied to the harvested crop stubble or soil surface without incorporation. Moisture in the form of rain or snow wi ll move 
and activate the product. Do not mechanically incorporate in the fall or spring after application because this activity may destroy the 
herbicide barrier and weed escapes can occur. Do not apply to frozen soils to prevent AUTHORITY 4F runoff from rain or snow that 
may occur following application. AUTHORITY 4F may be tankmixed with herbicides to control emerged weeds. Sequential 
applications may be needed depending on weed size. In situations where weed size may interfere with AUTHORITY 4F reaching the 
soil surface, a separate burndown application prior to the application of AUTHORITY 4F will be required. Use listed rates of burndown 
herbicides in combination with AUTHORITY 4F, or sequential applications as needed. Higher aerial spray volumes are required when 
there is a dense weed population or canopy. 
Spring Preemerge Application 
AUTHORITY 4F may be applied as a fallow treatment early in the spring provided the application is made prior to weed emergence, 
and adequate moisture is available to activate the AUTHORITY 4F. Follow the same use rate recommendations and application 
guidelines listed under the Fall Application section above.

Preplant (Fall Applications) 
AUTHORITY 4F may be applied in the fall as a preplant treatment prior to corn planting the following spring. 
 
AUTHORITY 4F can be used alone or in a tank mixture with other herbicides to control susceptible broadleaves, sedges and grasses 
in corn. Apply AUTHORITY 4F in conventional tillage or conservation tillage (reduced tillage or no-tillage) cropping systems using 
rates listed in the Table above. AUTHORITY 4F should be applied to the stubble or soil surface and allow moisture from rainfal l or 
snow to move the product into the soil. Do not mechanically incorporate in the fall or spring as this operation can destroy the herbicide 
barrier allowing weed escapes to occur. AUTHORITY 4F may be tankmixed with other burndown herbicides to control emerged 
weeds in the fall or residual soil herbicides that are labeled for fall use on corn. Select the correct AUTHORITY 4F use rate for corn 
from the Table above for your soil type and organic matter. Due to the extended period of time between the fall application and corn 
planting, the use rate of AUTHORITY 4F should be the mid to high rate within the rate range for the appropriate soil type and organic 
matter. 
 
Early Preplant and Preemergence (Spring Applications) 
AUTHORITY 4F may be applied preplant on the soil surface in the spring to control weeds in conventional and conservation tillag e 
systems. AUTHORITY 4F can be applied from 45 days prior to planting until 3 days after planting as a preemergence broadcast or 
banded soil application if corn seedlings have not broken the soil surface and if the seed furrow is completely closed. For 
preemergence applications 14 to 45 days prior to planting, use the mid to high rate in the appropriate rate range for the soil and 
organic matter type listed in Table above. AUTHORITY 4F can be tank mixed with other herbicides labeled for use in corn. To control 
insect pests such as cutworm or armyworm that may be present, AUTHORITY 4F may be tankmixed with insecticides including zeta-
cypermethrin or bifenthrin insecticides. If dry conditions persist following preemergence application of AUTHORITY 4F, a shallo w 
incorporation may be needed to activate the herbicide. If weeds are emerged at the time of AUTHORITY 4F application, use a 
burndown herbicide in conjunction with AUTHORITY 4F as needed. When planting into soil treated preplant with AUTHORITY 4F, 
minimize soil disturbance to maintain the herbicide barrier on the soil surface to achieve maximum weed control. Observe all 
precautions, instructions, and rotational cropping guidelines of each product’s label when tank mixing, including all reference s to 
potential carryover and crop injury warnings or restrictions. 
 
Preplant Incorporated 
AUTHORITY 4F may be applied as a Preplant Incorporated treatment in the spring prior to planting in reduced and conventional tillage 
corn. AUTHORITY 4F should be shallowly incorporated or mixed thoroughly into the soil to a maximum depth of 2 inches using a 
correctly adjusted implement such as a field cultivator, field finisher or disk harrow. Incorporating AUTHORITY 4F deeper than 2

Preemergence 
AUTHORITY 4F Herbicide may be applied to edamame as a preemergence treatment using rates listed on the table above. 
Preemergence treatments must be made within 3 days after plant ing before crop and weeds emerge. Applications should be made 
with ground equipment in a minimum of 10 gallons of finished spray per acre. 
 
Under extended periods of dry weather, adequate weed control may not be achieved. 
 
Some adverse crop response may occur on coarse textured soils with low organic matter (less than 1.5%) and pH of 7.8 or higher, or 
on highly eroded soils, or in areas of calcareous outcroppings. AUTHORITY 4F Herbicide use rates should be reduced in those 
areas. If applying AUTHORITY 4F to course textured soils with less than 1.5% organic matter, wait a minimum of 7 days after 
application before planting. Inadequate seed furrow closure or shallow planting (less than 1.0 inch) may result in undesirable crop 
response. As expected, poor growing conditions such as excessive moisture, low temperatures, soil compaction and diseases may 
also cause undesirable crop response.

Application Instructions 
AUTHORITY 4F may be preplant incorporated (to a depth no greater than 2 inches) up to 14 days prior to planting. Alternatively , 
AUTHORITY 4F may be applied to the soil surface at planting, or within 12 hours after planting. Incorporation of AUTHORITY 4F 
deeper than 2 inches can result in adverse crop response and/or inconsistent weed control. Do not use AUTHORITY 4F for “at-crack” 
type applications or apply to exposed peanut tissue. Such use can result in significant adverse crop response. For optimum 
performance, a combination of AUTHORITY 4F plus a grass herbicide labeled for peanuts is recommended. Under conditions of 
exceptionally high weed populations or when weeds not controlled by AUTHORITY 4F are anticipated, the use of suitable post-
emergent peanut herbicides is recommended. Broadcast apply the correct AUTHORITY 4F use rate from the tables below, in a 
minimum of 10 gallons of water per acre of finished spray. Banded AUTHORITY 4F application rates must be adjusted in proportion

(>85%) under certain circumstances. Otherwise, purple nutsedge will be partially controlled (71 to 84%). 
 
 
In soils with pH greater than 7, use the next lower AUTHORITY 4F application rate. Irrigation with alkaline (pH 8 to 9) water can result 
in adverse crop response. The extent of crop response is dependent on AUTHORITY 4F application rate, soil type (including %OM 
and pH), timing (after AUTHORITY 4F application relative to crop emergence), amount and pH of irrigation water. Do not irrigate with 
water greater than pH 9. 
 
After peanuts are established (4” to 6” across in size), the alkalinity of irrigation water has minimal impact on crop growth.

Ground and Aerial Applications 
Apply AUTHORITY 4F by aerial application as a preemergence treatment following planting and after dragoff, but prior to potato 
emergence. Optimum performance can be achieved if AUTHORITY 4F is applied to the soil surface and either rainfall or overhead 
irrigation is used to activate the product. If no moisture is received within 7 days following application in areas without ir rigation, a 
shallow incorporation (less than 2 inches) may be needed prior to weed and potato emergence to activate the product. Select the 
appropriate use rate based on soil texture and organic matter as shown in Table above. For control of emerged weeds at the time of 
the AUTHORITY 4F application, an appropriate burndown herbicide and adjuvants labeled for potatoes may be tankmixed with 
AUTHORITY 4F to control these weeds. Do not apply AUTHORITY 4F if the potatoes have emerged from the soil as undesirable 
crop response may occur. AUTHORITY 4F may be tankmixed with other soil-applied herbicides labeled for use in potatoes to improve 
weed management and increase weed control spectrum. 
 
Apply AUTHORITY 4F in a minimum of 10 gallons of spray by ground application and 5 gallons of spray by air. 
 
 
Chemigation Applications 
 AUTHORITY 4F may be applied to potatoes through sprinkler irrigation systems including center pivot, lateral move, end tow, so lid 
set or hand move irrigation systems. Apply AUTHORITY 4F prior to potato emergence using sufficient water (0.25 to 0.5 inch per 
acre) to provide thorough soil surface coverage, but to avoid runoff of irrigation water. AUTHORITY 4F may be applied with ot her 
products labeled for chemigation use in potatoes. 
 
It is important to note that irrigation with highly alkaline water (high pH) following a AUTHORITY 4F soil application may sign ificantly 
increase the amount of sulfentrazone available in soil solution. Irrigation with water having a pH greater than 7.5 could result in adverse 
crop response. This response will ultimately depend on initial AUTHORITY 4F application rate, application timing, amount and pH of 
irrigation water; the sensitivity of the crop and the crop growth stage when irrigated. The risk of adverse crop response will lessen with 
advances in the crop growth stage.

the AUTHORITY 4F Use Rate Table above. AUTHORITY 4F may be applied with ground or aerial sprayers calibrated to deliver a 
minimum of 10 gallons of finished spray by ground application and 5 gallons of finished spray by air. Use nozzle types and 
arrangements that will provide optimum coverage while producing a minimal amount of fine droplets. Apply sufficient spray volume to 
achieve adequate coverage. 
 
 
Preplant Incorporated and Preemergence Applications 
 AUTHORITY 4F can be applied prior to planting or up to 3 days after planting. When applications after planting are delayed greater 
than 3 days after planting, injury may occur if seeds are germinating. AUTHORITY 4F may be applied preemergence or preplant 
incorporated. For preplant incorporated applications, incorporation must be uniform and no deeper than 2 inches. Improper soi l 
incorporation may result in erratic weed control and/or crop injury. AUTHORITY 4F applied near or after crop emergence may cause 
severe injury to the crop. AUTHORITY 4F can be applied alone or in combination with other labeled soybean herbicides. 
AUTHORITY 4F may be followed by labeled postemergence soybean herbicides for increased control of grass and broadleaf weeds. 
. When using AUTHORITY 4F in no-till or minimum till cropping systems, tank mix with an appropriate burndown herbicide for 
improved control of existing weeds. 
 
Fall Applications 
 AUTHORITY 4F may be applied as a fall treatment to the stubble of harvested crops for the burndown of existing vegetation and 
preemergence control of labeled weeds the following spring in no-till and conservation tillage production systems. Fall applications of 
AUTHORITY 4F must be made in weed control programs that include, as needed, spring applications of preplant, preemergence or 
postemergence herbicides for the following crop season. AUTHORITY 4F can be applied to the stubble of a harvested crop in no-till 
or to the soil surface of conservation tillage fields after harvest when the sustained soil temperature is 55 degrees F and fal ling at a 
soil depth of 4 inches. Apply after September 30 in those areas North of Interstate 90 and after October 15 in those areas North of 
Interstate 70. Do not apply AUTHORITY 4F as a fall treatment South of Interstate 70. Applications to ridge till production sy stems 
must be made after the formation of ridges or bedded. 
 
If weeds are emerged at the time of application, utilize a tank mixture with a suitable burndown herbicide at labeled rates. Fall applied 
burndown treatments should be made with a minimum of 20 gallons per acre to achieve adequate coverage of the weeds being 
treated. When making burndown applications to emerged weeds, the addition of adjuvants such as COC or MSO to the spray mixture 
can be used to enhance the burndown activity of the application. 
 
Weeds Controlled 
When applied according to directions, AUTHORITY 4F will provide control of: 
Amaranth, Palmer Ni

When applying AUTHORITY 4F with other registered herbicides, refer to specific label information on precautions, instructions, 
limitations, application methods and timings, and weeds controlled. 
 
AUTHORITY 4F is especially effective against a wide range of economic broadleaf and grass weeds. The same processes that 
sulfentrazone affects in these weeds can, under certain conditions, be affected in soybeans. These conditions include high pH ( 7.5 
and above), cool weather, prolonged and excessive moisture, seedling diseases, and any other condition, including poor agronomic 
practices, that are unfavorable to vigorous crop growth. Such effects in soybeans are often observed as stunting and discolorat ion. 
The duration of these effects are somewhat dependent on the duration of the adverse growing conditions. These effects lessen an d 
generally diminish with the return to normal growing conditions.

Fall Applications 
AUTHORITY 4F may be applied in the fall as a preplant treatment to control or suppress weeds prior to planting the following spring. 
AUTHORITY 4F should be applied to the stubble or soil surface and allow moisture from rainfall or snow to move the product into the 
soil. Do not mechanically incorporate in the fall or spring as this can destroy the herbicide barrier and allowing weed escapes to occur. 
Do not apply to frozen soils or to existing snow cover to prevent AUTHORITY 4F runoff from rain or snow melt that may occur following 
application. AUTHORITY 4F may be tank mixed with other residual soil herbicides that are labeled for fall use on sunflowers. If weeds 
are emerged at the time of AUTHORITY 4F application, use a burndown herbicide such as glyphosate or paraquat at the full-labeled 
rate in combination with AUTHORITY 4F or split application as needed. Select the appropriate rate from Table above within the 
correct soil type and organic matter range. When applying AUTHORITY 4F in the fall, use a mid to high rate within the rate range for 
the appropriate soil type and organic matter. 
 
Early Preplant and Preemergence (Spring Applications) 
 AUTHORITY 4F may be applied preplant on the soil surface in the spring to control weeds. AUTHORITY 4F can be applied early 
preplant prior to planting up to 3 days after planting as a preemerge soil application if seedlings have not broken the soil surface and 
if the seed furrow is completely closed. For preemerge applications greater than 3 weeks prior to planting, use the high rate within 
the appropriate rate range for the soil and organic matter type listed in the use rate chart above. If applying Authority 4F to course 
textured soils with less than 1.5% organic matter, wait a minimum of 7 days after application before planting. AUTHORITY 4F c an 
be tank mixed with other preemerge herbicides labeled for sunflowers. If dry conditions persist following preemerge applicatio n of 
AUTHORITY 4F, a shallow incorporation may be needed to incorporate and activate the herbicide. If weeds are emerged at the time 
of AUTHORITY 4F application, use a burndown herbicide at the full-labeled rate in combination with AUTHORITY 4F or split 
application as needed. 
 
Preplant Incorporated (PPI) 
AUTHORITY 4F may be applied as a Preplant Incorporated treatment in the spring prior to planting in reduced and conventional 
tillage. AUTHORITY 4F should be shallowly incorporated in the soil no deeper than 2 inches. Incorporating AUTHORITY 4F deeper 
than 2 inches can result in inconsistent weed control. Use the appropriate rate from Table above for the soil texture, organic matter, 
and pH level. AUTHORITY 4F can be tankmixed with other soil-applied herbicides labeled for preplant incorporation in sunflowers . 
Weeds Controlled 
When applied according to directions, AUTHORITY 4F will provide control of: 
Amaranth, Palmer Pi gweed, redroot 
Filaree, redstem Pi gweed, smooth 
Kochia (ALS and Triazine Resistant) Sida, prickl y

For information on other weeds not listed above, refer to Weeds List section (Table 5) in this label. 
 
When applying AUTHORITY 4F to coarse textured soils, it is recommended that growers allow a minimum of 7-14 days from 
application to planting. Best results are achieved with AUTHORITY 4F when applications are made early preplant and greater tha n 
14 days before planting. 
 
Some adverse crop response may occur on coarse textured soils with low organic matter (less than 1.5%) and pH of 7.8 or higher, or 
on highly eroded soils, or in areas of calcareous outcroppings. AUTHORITY 4F use rates should be reduced in those areas. 
Inadequate seed furrow closure or shallow planting (less than 1.0 inch) may result in undesirable crop response. As expected, poor 
growing conditions such as excessive moisture, low temperatures, soil compaction and diseases may also cause undesirable crop 
response. 
 
These Crop Specific Use Directions are based upon the interactive effects of AUTHORITY 4F (sulfentrazone) and the primary soil 
and environmental factors, which affect its activity on various weed species and tolerance among crops. The user is required to

Fall Applications) 
AUTHORITY 4F may be applied in the fall as a preplant treatment to control or suppress weeds prior to planting the following spring. 
AUTHORITY 4F should be applied to the stubble or soil surface and allow moisture from rainfall or snow to move the product into the 
soil. Do not mechanically incorporate in the fall or spring as this can destroy the herbicide barrier and allowing weed escapes to occur. 
Do not apply to frozen soils or to existing snow cover to prevent AUTHORITY 4F runoff from rain or snow melt that may occur following 
application. AUTHORITY 4F may be tank mixed with other residual soil herbicides that are labeled for fall use on sunflowers or other 
crops in subgroup 20B. If weeds are emerged at the time of AUTHORITY 4F application, use a burndown herbicide such as glyphosate 
or paraquat at the full-labeled rate in combination with AUTHORITY 4F or split application as needed. Select the appropriate r ate 
from Table above within the correct soil type and organic matter range. When applying AUTHORITY 4F in the fall, use a mid to high 
rate within the rate range for the appropriate soil type and organic matter. 
 
Early Preplant and Preemergence (Spring Applications) 
 AUTHORITY 4F may be applied preplant on the soil surface in the spring to control weeds. AUTHORITY 4F can be applied early 
preplant prior to planting up to 3 days after planting as a preemerge soil application if seedlings have not broken the soil surface and 
if the seed furrow is completely closed. For preemerge applications greater than 3 weeks prior to planting, use the high rate within 
the appropriate rate range for the soil and organic matter type listed in the use rate chart above. If applying Authority 4F to coarse 
textured soils with less than 1.5% organic matter, wait a minimum of 7 days after application before planting. AUTHORITY 4F c an 
be tank mixed with other preemerge herbicides labeled for sunflowers or other crops in subgroup 20B. If dry conditions persist 
following preemerge application of AUTHORITY 4F, a shallow incorporation may be needed to incorporate and activate the herbicide. 
If weeds are emerged at the time of AUTHORITY 4F application, use a burndown herbicide at the full-labeled rate in combination with 
AUTHORITY 4F or split application as needed. 
 
Preplant Incorporated (PPI) 
AUTHORITY 4F may be applied as a Preplant Incorporated treatment in the spring prior to planting in reduced and conventional 
tillage. AUTHORITY 4F should be shallowly incorporated in the soil no deeper than 2 inches. Incorporating AUTHORITY 4F deeper 
than 2 inches can result in inconsistent weed control. Use the appropriate rate from Table above for the soil texture, organic matter, 
and pH level. AUTHORITY 4F can be tankmixed with other soil-applied herbicides labeled for preplant incorporation in sunflowe rs 
or other crops in subgroup 20B. 
 
Weeds Controlled 
When applied according to directions, AUTHORITY 4F will provide control of: 
Amaranth, Palmer Pi gweed, redroot

For information on other weeds not listed above, refer to Weeds List section (Table 5) in this label. 
 
When applying AUTHORITY 4F to coarse textured soils, it is recommended that growers allow a minimum of 7-14 days from 
application to planting. Best results are achieved with AUTHORITY 4F when applications are made early preplant and greater tha n 
14 days before planting. 
 
Some adverse crop response may occur on coarse textured soils with low organic matter (less than 1.5%) and pH of 7.8 or higher, or 
on highly eroded soils, or in areas of calcareous outcroppings. AUTHORITY 4F use rates should be reduced in those areas. 
Inadequate seed furrow closure or shallow planting (less than 1.0 inch) may result in undesirable crop response. As expected, poor

Page 22 
growing conditions such as excessive moisture, low temperatures, soil compaction and diseases may also cause undesirable crop 
response.

Poor agronomic practices, unfavorable pH soils, diseases, cold weather, excessive moisture, drought or other conditions unfavorable 
to normal plant growth may adversely affect the growth of tobacco transplants. Weakened transplants may be more susceptible to 
herbicide response and diseases, particularly under poor drainage or compacted soil conditions or when the soil has been saturated 
for long periods of time. Contact your State Agricultural Extension Service Specialist for consultation as to the agronomic 
recommendations suited for your tobacco varieties and local conditions. Temporary stunting of tobacco may occur if transplants are 
set too shallowly, or if heavy rainfall occurs immediately following transplanting. Splashing of treated soil onto tobacco lea ves may 
cause some localized and inconsequential necrosis. Use sound transplanting practices that ensure treated soil will not wash or crust 
over tobacco plants.

Early Preplant and Fall Applications 
AUTHORITY 4F may be applied in the fall as a preplant treatment to control or suppress weeds prior to planting the following spring. 
AUTHORITY 4F should be applied to the stubble or soil surface and allow moisture from rainfall or snow to move the product into the 
soil. Do not mechanically incorporate in the fall or spring as this can destroy the herbicide barrier and weed escapes can occur. Do 
not apply to frozen soils or to existing snow cover to prevent AUTHORITY 4F runoff from rain or snow melt that may occur follow ing 
application. AUTHORITY 4F may be tank mixed with other residual soil herbicides that are labeled for fall use on dry bean and dry 
peas. If weeds are emerged at the time of AUTHORITY 4F application, use a burndown herbicide such as glyphosate or paraquat at 
the full-labeled rate in combination with AUTHORITY 4F or split application as needed. Select the appropriate rate from Table above 
within the correct soil type and organic matter range. When applying AUTHORITY 4F in the fall, use a mid to high rate within the rate 
range for the appropriate soil type and organic matter. 
 
Early Preplant and Preemergence (Spring Applications) 
AUTHORITY 4F may be applied preplant on the soil surface in the spring to control weeds in dry bean and dry peas. AUTHORITY 
4F can be applied early preplant prior to planting up to 3 days after planting as a preemerge soil application if seedlings hav e not 
broken the soil surface and if the seed furrow is completely closed. For preemerge applications greater than 3 weeks prior to planting, 
use the high rate within the appropriate rate range for the soil and organic matter type listed in the use rate chart above. If applying 
Authority 4F to course textured soils with less than 1.5% organic matter, wait a minimum of 7 days after application before pla nting. 
AUTHORITY 4F can be tank mixed with other preemerge herbicides labeled for dry bean and dry peas use. If dry conditions persist 
following preemerge application of AUTHORITY 4F, a shallow incorporation may be needed to incorporate and activate the herbicide. 
If weeds are emerged at the time of AUTHORITY 4F application, use a burndown herbicide at the full-labeled rate in combination with 
AUTHORITY 4F or split application as needed. 
 
Preplant Incorporated (PPI) 
AUTHORITY 4F may be applied as a Preplant Incorporated treatment in the spring prior to planting in reduced and conventional tillage 
dry bean and dry pea. Do not incorporate to depths greater than 2 inches. AUTHORITY 4F use rates for PPI applications are similar 
to those used in preplant and preemergence applications. AUTHORITY 4F can be tankmixed with other burndown or soil-applied 
herbicides labeled for use in dry bean or dry pea. Use the listed rates of burndown herbicides, or split applications as needed. Observe 
all precautions, instructions, and rotational cropping guidelines of each product’s label when tank mixing, including all refer ences to 
potential carryover and crop injury warnings or restrictions. 
 
Weeds Controlled 
When applied according to directions, AUTHORITY 4F will provide control of: 
Amaranth, Palmer Pi
gweed, redroot 
Filaree, redstem Pi gweed, smooth 
Kochia (ALS and Triazine Resistant) Sida, prickl y 
Lambsquarters, common Thistle, Russian 
Morningglory, ivyleaf Waterhemp, common 
Morningglory, tall Waterhemp, tall 
Nightshade, Eastern black 
 
For information on other weeds not listed above, refer to Weeds List section (Table 5) in this label. 
 
When applying AUTHORITY 4F to coarse textured soils, it is recommended that growers allow a minimum of 7-14 days from 
application to planting. Best results are achieved with AUTHORITY 4F when applications are made early preplant and greater tha n 
14 days before planting. 
Under extended periods of dry weather, adequate weed control may not be achieved. 
 
Some adverse crop response may occur on coarse textured soils with low organic matter (less than 1.5%) and pH of 7.8 or higher, or 
on highly eroded soils, or in areas of calcareous outcroppings. AUTHORITY 4F use rates should be reduced in those areas. 
Inadequate seed furrow closure or shallow planting (less than 1.0 inch) may result in undesirable crop response. As expected, poor 
growing conditions such as excessive moisture, low temperatures, soil compaction and diseases may also cause undesirable crop 
response.

Some adverse crop response may occur on coarse textured soils with low organic matter (less than 1.5%) and pH of 7.8 or higher, or 
on highly eroded soils, or in areas of calcareous outcroppings. AUTHORITY 4F Herbicide use rates should be reduced in those 
areas. If applying AUTHORITY 4F to course textured soils with less than 1.5% organic matter, wait a minimum of 7 days after 
application before planting. Inadequate seed furrow closure or shallow planting (less than 1.0 inch) may result in undesirable crop 
response. As expected, poor growing conditions such as excessive moisture, low temperatures, soil compaction and diseases may 
also cause undesirable crop response.

Fall Applications 
AUTHORITY 4F Herbicide may be applied in the fall as a preplant treatment to control or suppress weeds prior to planting flax t he 
following spring. AUTHORITY 4F Herbicide should be applied to the stubble or soil surface and allow moisture from rainfall or snow 
to move the product into the soil. Do not mechanically incorporate in the fall or spring as this can destroy the herbicide bar rier and 
allow weed escapes to occur. Do not apply to frozen soils or to existing snow cover to prevent AUTHORITY 4F Herbicide runoff from 
rain or snow melt that may occur following application. If weed s are emerged at the time of AUTHORITY 4F Herbicide application, 
use a labeled burndown herbicide at the full-labeled rate in combination with AUTHORITY 4F Herbicide or a sequential applicatio n 
as needed. Select the appropriate rate from the Table above within the correct soil type and organic matter range. When apply ing 
AUTHORITY 4F Herbicide in the fall, use a mid to high rate within the rate range for the appropriate soil type and organic matter. 
 
Early Preplant and Preemergence (Spring Applications) 
AUTHORITY 4F Herbicide may be applied preplant on the soil surface in the spring to control weeds in flax. AUTHORITY 4F Herbicide 
can be applied early preplant prior to planting up to 3 days after planting as a preemerge soil application if seedlings have not broken 
the soil surface and if the seed furrow is completely closed. AUTHORITY 4F Herbicide applied after crop emergence may cause 
severe injury to the crop. For preemerge applications greater than 3 weeks prior to planting, use the mid to high rate within the 
appropriate rate range for the soil and organic matter type listed in the use rate chart above. AUTHORITY 4F Herbicide can be applied 
alone or in combination with other labeled flax herbicides. Always follow the most restrictive label when tank mixing. AUTHORITY 4F 
Herbicide may be followed by labeled postemergence flax herbicides for increased control of grass and broadleaf weeds. If dry 
conditions persist following preemerge application of AUTHORITY 4F Herbicide, weed control may be poor. If weeds are emerged 
at the time of AUTHORITY 4F Herbicide application, use a burndown herbicide at the full-labeled rate in combination with AUTHORITY 
4F Herbicide or split application as needed. When using AUTHORITY 4F Herbicide in no-till or minimum till cropping systems, ta nk 
mix with an appropriate burndown herbicide for improved control of existing weeds. 
 
Preemergence 
AUTHORITY 4F Herbicide can be applied prior to planting to anytime after planting but before seedlings have emerged. AUTHORITY 
4F Herbicide applied after crop emergence may cause severe injury to the crop. AUTHORITY 4F Herbicide can be applied alone or 
in combination with other labeled flax herbicides. AUTHORITY 4F Herbicide may be followed by labeled postemergence flax 
herbicides for increased control of grass and broadleaf weeds. When using AUTHORITY 4F Herbicide in no-till or minimum till 
cropping systems, tank mix with an appropriate burndown herbicide for improved control of existing weeds. 
 
When applied according to directions, AUTHORITY 4F Herbicide will provide control of: 
Copperleaf, hophornbeam Mornin

Kochia (ALS and Triazine 
Resistant) 
Nightshade, Eastern black 
Morningglory, entireleaf Pi gweed, redroot 
Morningglory, ivyleaf Pi gweed, smooth 
 
When applying AUTHORITY 4F Herbicide to coarse textured soils, growers are to allow a minimum of 7-14 days from application to 
planting. Some adverse crop response may occur on coarse textured soils with low organic matter (less than 1.5%) and pH of 7.2 
or higher, or on highly eroded soils, hilltops or in areas of calcareous outcroppings. AUTHORITY 4F Herbicide use rates should be 
reduced to 3.0 fl oz/A in those areas or AUTHORITY 4F Herbicide should not be used in those areas. Inadequate seed furrow closure 
or shallow planting (less than 1.0 inch) may result in undesirable crop response. As expected, poor growing conditions such as 
excessive moisture, low temperatures, soil compaction and diseases may also cause undesirable crop response.

APPLICATION INFORMATION 
AUTHORITY 4F should be applied as a uniform broadcast soil application to orchard and vineyard floors and to berry beds and furrows 
or as a uniform band application directed to the base of the trunk in trees and vines and to the base of the berry and beds in berry’s 
to provide preemergence control of weeds in Table listed on this section. 
 
For best control, AUTHORITY 4F should be applied when there are no weeds present or a postemergence herbicide is tank mixed to 
eliminate emerged weeds.

Page 38 
For broadcast applications, a single application of AUTHORITY 4F should be made at 4 to12 fl oz/A (0.125 to 0.375 lb ai/A). Do not 
apply more than 12 fl oz/A (0.375 lb ai/A) per twelve-month period. The twelve-month period is considered to begin when the in itial 
application of AUTHORITY 4F is applied. 
 
For improved weed management, AUTHORITY 4F can be applied in a tank mixture with other preemergence and postemergence 
burndown herbicides. Burndown herbicides may include, but are not limited to, carfentrazone-ethyl, glyphosate, paraquat, 
glufosinate-ammonium, and 2,4-D. Do not tank mix with flumioxazin herbicides ( or with other products containing sulfentrazone. 
 
When applied as a banded treatment (50% band or less), refer to formula in chart below for rate and volume. AUTHORITY 4F may 
be applied twice per year. Do not apply more than 12 fl oz/A product (0.375 lb ai/A) on a broadcast application basis per twelve-month 
period. Allow a minimum of 60 days between applications, unless otherwise specified on the label or separate published FMC 
recommendations. 
 
For band treatments, apply the broadcast equivalent rate and volume per acre. To determine these:
 
 
Band Width inches X Broadcast 
Rate Per Acre = Band Rate 
Row Width inches 
 
Band Width inches X Broadcast 
Volume Per Acre = Band Volume 
 
A minimum of 10 gallons of spray solution per acre should be used to ensure uniform spray coverage. Nozzle selection should meet 
manufacturer’s spray volume and pressure recommendations for preemergence and postemergence herbicide applications. The 
spray solution should have a pH between 5.0 and 9.0. 
 
For apples, citrus fruits, tree nuts (except walnuts), grapes and berries, only apply AUTHORITY 4F to crops that have been established 
for two full growing season and are in good health and vigor. For walnuts, only apply AUTHORITY 4F to crops that have been 
established for three full growing seasons and are in good health and vigor.. Avoid contact of the spray solution on the green bark of 
trunks of young vines and trees by wrapping the trunk with a nonporous wrap, grow tubes, or wax containers which will keep the spray 
solution from coming in direct contact with the green tissue. Avoid direct or indirect spray contact with crop foliage and fruit. 
 
Use ground equipment only. Do not apply using an airblast sprayer or by air. Do not apply using a mechanically pressurized handgun. 
 
Best results are obtained when the soil is moist at the time of application and the application will be followed by at least ½ inch of 
rainfall or sprinkler irrigation within two weeks after application. Applications should be timed to take advantage of normal rainfall 
patterns and cool temperatures, especially where drip or micro sprinkler irrigation is used which may not uniformly incorporate the 
herbicide. 
 
WEED CONTROL INFORMATION 
 
AUTHORITY 4F is a selective soil-applied herbicide for the control of susceptible broadleaf, grass and sedge weeds found in the 
Permanent Crop Weed list in this section. Adequate moisture of at least ½ inch is required within 14 days after application for optimal 
control. If adequate rainfall is not received in a timely fashion, irrigate with a minimum of ½ inch of water. When activating moisture 
is delayed, a reduced level of weed control may occur. These escaped weeds can be removed using a burndown herbicide. 
 
Tank mix AUTHORITY 4F with a burndown herbicide and use an appropriate adjuvant when weeds are present at the time of 
application. Refer to the tank mix partner’s product label for the proper use rates by weed sizes. 
 
Residual weed control may be reduced when AUTHORITY 4F is applied where heavy crop trash such as leaves and branches and 
/or weed residues exists. It is best to rake
 or blow off the leaves and trash when they fall and prior to the AUTHORITY 4F application. 
 
Do not apply after petal fall unless using a hooded or shielded sprayer to ensure that the spray solution will not come in contact with 
the crop or foliage.

ANNUAL AND PERENNIALSEDGE CONTROL INCLUDING NUTSEDGE 
AUTHORITY 4F applied at 12.0 fl oz/A (0.375 lb ai/A) may provide control or suppression of sedges whether applied preemergence 
or postemergence to the sedges. Postemergence applications to sedges allow AUTHORITY 4F to be taken into the sedge through 
the foliage as well as soil uptake through the roots. Soil uptake is the major means of uptake by sedges. Good spray coverage is 
required for optimum control of sedges especially when applying postemergence to the sedges. Use a quality federally approved 
nonionic surfactant (NIC) at the rate of 0.25% v/v when applying postemergence. 
 
When applied as directed, AUTHORITY 4F will provide control or suppression of the following sedges. 
 
Common Name Scientific Name 
Kyllinga, green Kyllinga brevifolia 
Kullinga, false green Kyllinga gracillima 
Nutsedge, purple Cyperus rotundus 
Nutsedge, yellow Cyperus esculentus 
Sedge, cylindrical Cyperus retrorsus 
Sedge, globe Cyperus globulosus 
Sedge, Surinam Cyperus surinamensis 
Sedge, Texas Cyperus polystachyos 
 
Optimum control of purple nutsedge may be obtained using split applications of AUTHORITY 4F. Apply 4.0-6.0 fl oz/A followed by a 
second application to actively growing purple nutsedge. Do not exceed the maximum rate of 12.0 fl oz/A (0.375 lb ai/A) per twe lve-
month period. AUTHORITY 4F symptoms on purple nutsedge will be observed as reduced nutsedge stands, necrosis, chlorosis, 
and/or stunting. Optimum control may not be observed until the second year after the original treatment.

AUTHORITY 4F Herbicide is a selective soil applied herbicide for the control of certain broadleaf weeds, grasses and sedges. When 
applied according to directions, it will provide control of susceptible species. AUTHORITY 4F Herbicide is formulated as flowab le 
(suspension concentrate) containing four pounds of the active ingredient sulfentrazone per gallon. 
The mode of action of AUTHORITY 4F Herbicide involves uptake by weed roots and shoots. Observe all instructions, mixing directions, 
application precautions and other label information of each product when tank mixing with AUTHORITY 4F Herbicide. 
 
AUTHORITY 4F may be applied to established seeded, sodded or sprigged turfgrasses following the second mowing for the control 
of key grass, sedge and broadleaf weeds. Turf grasses should have developed a good root system, a uniform stand with healthy root 
systems to fill in the exposed edges prior to application. Turf injury could result from application of this product on turf that is not well 
established or has been weakened by stresses such as unfavorable weather conditions, diseases, chemical, recent harvesting or 
mechanical influences.
