WEED RESISTANCE MANAGEMENT 
 
Authority 75 DF Herbicide 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 more 
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 rates of Authority 75 DF Herbicide 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 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 sites of actions for each target weed. 
· 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 14 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 75 DF Herbicide is a selective soil-applied herbicide for the control of susceptible broadleaf, grass and sedge weeds . 
Authority 75 DF Herbicide is formulated as a 75% water dispersible granule 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 75 DF Herbicide 
treatment, a shallow incorporation may be needed to obtain desired weed control. When activating moisture is received after 
dry conditions, Authority 75 DF Herbicide will provide a reduced level of control of susceptible germinating weeds. Soil appli cations 
of Authority 75 DF Herbicide must be made before crop seed germination to prevent injury to the emerging crop seedlings. Whe n 
applications after planting are delayed, injury may occur if seeds are germinating or if they are located near the soil surface . Under 
extended periods of dry weather, adequate weed control may not be achieved. 
 
Observe all instructions, crop restrictions, mixing directions, application precautions, replanting directions, rotational crop guidelines 
and other label information of each product when tank mixing with Authority 75 DF Herbicide. 
 
Proper handling instructions : Authority 75 DF Herbicide 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 an d 
reservoirs. This 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 washwater, and rainwater that may fall on the pad. Surface w ater 
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 containment 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

Authority 75 DF Herbicide Page 4 
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. 
 
PRODUCT APPLICATION INSTRUCTIONS 
Authority 75 DF Herbicide 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 various 
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 75 DF Herbicide rates that could result in adverse crop response. 
 
All soil applications and the residual activity of post-plant applications of Authority 75 DF Herbicide require adequate moistu re for 
herbicidal 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 dependent 
on rainfall, Authority 75 DF Herbicide can await activating moisture for extended periods (10 to 14 days or longer) depending o n the 
soil parameters described above. Once activated, Authority 75 DF Herbicide 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 pr ovided 
activation, particularly for surface applications of Authority 75 DF Herbicide, a shallow incorporation is recommended for dest ruction 
of any germinating weeds and to incorporate Authority 75 DF Herbicide. 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, alter native 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 75 DF Herbicide. 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 
as well. 
 
AUTHORITY 75 DF HERBICIDE PRODUCT USE RATES 
The following directions for the selection of Authority 75 DF Herbicide application rates are critical to achieve maximum performance 
and to insure maximum crop safety. The user is required to read and follow the specific Authority 75 DF Herbicide use directions and 
restrictions for each crop as defined in subsequent sections of this label. The user is cautioned that some crops respond diff erently 
to Authority 75 DF Herbicide. This response is governed by the Authority 75 DF Herbicide application rate, various soil factor s and 
inherent crop sensitivity. The Crop Specific Use Directions have been designed to minimize the risk of adverse crop response wh ile 
maintaining optimum weed control. 
 
Mode of Action 
Sulfentrazone, the active ingredient in Authority 75 DF Herbicide, is a potent inhibitor of the enzyme Protoporpyrinogen Oxidas e 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 death. The selective herbicidal activity of sulfentrazone is based on its greater affinity for the PPO IX enzyme in weed species 
versus crop plants. 
 
Mechanism of Action 
Following the application of Authority 75 DF Herbicide to soil, germinating seeds and seedlings take up sulfentrazone from the soil 
solution. The amount of sulfentrazone in soil solution, and ava ilable for weed uptake, is determined primarily by soil type, or ganic 
matter and soil pH. Sulfentrazone adsorbs to the clay and organic matter (OM) fractions of soils; effectively limiting the amou nt 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 75 DF Herbicide 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 affect 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 (particularly clay 
content), % organic matter and pH. The application timing (relative to the emergence of the crop and weeds) and amount of rain fall

Authority 75 DF Herbicide Page 5 
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 75 DF Herbicide 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 an Authority 75 DF Herbicide soil applic ation can 
also significantly increase the amount of sulfentrazone available in the 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 75 DF Herbicide application rate, timing, 
amount and pH of irrigation water and sensitivity of the crop and it’s growth stage when irrigated. The risk of adverse crop re sponse 
will lessen with the advance in growth stage among most crops. 
 
The following Crop Specific Use Directions have been designed with specific Authority 75 DF Herbicide instructions for each cro p 
based on the soil type, soil organic matter, and soil pH interactions described above. The user is cautioned that crop toleran ce and 
weed control performance are based on strict adherence to these instructions. 
 
SPRAY DRIFT 
Ground Application 
Spray Volume 
Ground applicators must use a minimum finished spray of 10 gallons per acre. When sulfentrazone is tank mixed with a contact 
burndown herbicide, ground applicators must use a minimum spray volume of 15 gallons per acre. 
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 pressu res. Utilize nozzles that produce minimal amounts of fine sp ray 
droplets to avoid spray drift or inadequate foliar and/or soil coverage. 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. 
 
Aerial Application 
Use Restrictions 
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. 
 
Do not apply when wind speed favors drift beyond the area intended for treatment. 
 
The following drift management 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 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). 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 ASAE standard). 
 
 
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 recommended 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 deflection 
from horizontal will reduce droplet size and increase drift potential.

Authority 75 DF Herbicide Page 6 
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 - Aerial applications should not be made at a height greater than 10 feet above the top of the target plant canopy 
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 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 compensate 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). 
 
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 75 DF Herbicide 
Drift of dilute spray mixtures containing Authority 75 DF Herbicide must be prevented. Observation of the preceding environment al 
conditions, correct application equipment design, calibration and application practices will significantly diminish the risk of off-target 
spray drift. Authority 75 DF Herbicide can cause significant symptomology by drift on to sensitive crops and other plants. Thi s 
symptomology may manifest initially as discreet, localized spots where contacted by Authority 75 DF Herbicide drift mixtures. 
Depending on concentration of the spray solution and droplets size (effectively determining the dosage of sulfentrazone) and al so 
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 environmental prohibitions that then result in off-target movement or drift of Authority 75 DF Herbicide o n 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 75 DF Herbicide. 
 
Chemigation Application 
 Authority 75 DF Herbicide may be applied through sprinkler irrigation systems including center pivot, lateral move, end tow, solid set, 
or hand 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 make necessary adjustments should the need arise. 
 
It is important to note that irrigation with highly alkaline water (high pH) following a Authority 75 DF Herbicide 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 75 DF Herbicide 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 75 DF Herbicide Page 7 
Authority 75 DF Herbicide should be metered into the irrigation system continuously for the duration of the water application. Authority 
75 DF Herbicide should be diluted in sufficient volume to insure 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 ma intain 
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 uniform 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 75 DF HERBICIDE 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 avera ge 
of at least 25 individuals daily at least 60 days of the year. Authority 75 DF Herbicide may be applied through irrigation sy stems, 
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 is no blockage of the overflow of the reservoir tank. 
 
Application with Dry Fertilizers 
 Authority 75 DF Herbicide may be applied impregnated on dry fertilizers. When applied as directed with adequate soil coverage , 
Authority 75 DF Herbicide dry bulk fertilizer mixtures will provide satisfactory weed control. 
 
Follow all Authority 75 DF Herbicide label directions regarding product use rates per acre, registered crops, incorporation, sp ecial 
instructions and precautions. 
 
Apply Authority 75 DF Herbicide/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 75 DF Herbicide/dry fertilizer mixture. 
 
 
Impregnation Directions 
To impregnate Authority 75 DF Herbicide 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 75 DF Herbicide in a clean container using clear water. Slowly add the Authority 75 DF Herbicide/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 75 DF Herbicide 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 75 DF Herbicide dry bulk fertilizer with an accurately calibrated dry fertilizer spreader. The Authority 7 5 DF 
Herbicide dry bulk fertilizer mixture must be spread uniformly on the soil surface. Uneven spreading leaving untreated areas c an 
cause poor weed control or overlapping areas with potential increased Authority 75 DF Herbicide use rates could result in possi ble 
crop response. 
 
A minimum of 200 pounds of dry bulk fertilizer impregnated with the listed amount of Authority 75 DF Herbicide must be applied per 
acre to achieve adequate soil coverage for satisfactory weed control. 
 
DO NOT impregnate Authority 75 DF Herbicide onto coated ammonium nitrate or limestone because these materials will not absorb 
the herbicide. 
 
Refer to the appropriate crop section of the Authority 75 DF Herbicide label to determine the rate of Authority 75 DF Herbicide to be 
applied per acre. Use the following table to determine the amount of Authority 75 DF Herbicide to be impregnated on a ton (200 0 
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 75 DF Herbicide to be impregnated on a ton of dry 
bulk fertilizer using the following formula:

Application with Liquid Fertilizer 
Authority 75 DF Herbicide may be applied using liquid fertilizer solutions as the carrier. The fertilizer solutions may either be 
concentrate formulations as blended or diluted with water. When applied as directed with adequate soil coverage, Authority 75 DF 
Herbicide applied with liquid fertilizer mixtures will provide satisfactory weed control. However, adequate soil coverage is essential to 
achieve acceptable 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 mixtur e 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 75 DF Herbicide in a clean container with clean water using equal volumes of Authority 75 DF Herbicide and clean 
water. Slowly add the Authority 75 DF Herbicide/water slurry to the spray tank. Carefully rinse the slurry container, adding the rinsate 
to the spray tank. Better mixing of the Authority 75 DF Herbicide/water slurry may be achieved if the slurry is added using in duction 
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 
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. Insure the Authority 75 DF Herbicide slurry is thoroughly mixed before application. 
 
For tank mixtures with other herbicide(s), a compatibility test must be conducted to insure product compatibility before mixing. Read 
and follow all the directions, precautions and restrictions of the tank mixture products prior to mixing. 
 
Apply the Authority 75 DF Herbicide spray mixture immediately after mixing. Do not store the sprayer overnight or for any exten ded 
period of time with the Authority 75 DF Herbicide spray mixture remaining in the tank. 
 
 
Do not premix Authority 75 DF Herbicide spray solutions in nurse tanks. 
 
Follow all Authority 75 DF Herbicide label directions regarding product use rates per acre, registered crops, application instr uctions, 
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 75 DF Herbicide and fertilizer mixture.

MIXING AND LOADING INSTRUCTIONS 
Authority 75 DF Herbicide may be applied alone, or in tank mixtures with other herbicides for the control of additional weed species. 
Mixtures with some other pesticides have not been tested. Conduct appropriate compatibility tests prior to tank mixing with oth er 
pesticides. 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 75 DF Herbicide 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 75 DF Herbicide in a clean container using clean water. Slowly add the Authority 75 DF Herbicide/water 
slurry to the spray tank. Carefully rinse the slurry container, adding the rinsate to the spray tank. Complete filling the s pray tank to 
the desired level. Continuous spray tank agitation is required at all times to maintain a uniform spray solution. Make sure Au thority 
75 DF Herbicide is thoroughly mixed before application or before adding another product to the spray tank. 
 
Use the Authority 75 DF Herbicide spray mixture immediately after mixing. Do not store the sprayer overnight or for any extende d 
period of time with the Authority 75 DF Herbicide spray mixture remaining in the tank. 
 
Do not premix Authority 75 DF Herbicide spray solutions in nurse tanks. 
 
If Authority 75 DF Herbicide is tank mixed with other herbicides, all additional directions, restrictions and precautions for t he tank 
mixture herbicides must be followed. 
 
SPRAYER EQUIPMENT CLEAN-OUT 
As soon as possible after spraying Authority 75 DF Herbicide and before using sprayer equipment for any other applications, 
the sprayer must be thoroughly cleaned to avoid potential crop affects 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 75 DF Herbicide 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. 
 
2. Prepare a sprayer cleaning solution by adding three gallons of ammonia (containing at least 3% active) per 100 gallons of c lean 
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 75 DF Herbicide spray solution remaining i n 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 75 DF Herbicide remain in inadequately cleaned mixing, loading and/or spray equipment, the y 
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 of 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.

Preplant (Fall Applications) 
Authority 75 DF Herbicide may be applied in the fall as a preplant treatment prior to corn planting the following spring. 
 
Authority 75 DF Herbicide can be used alone or in a tank mixture with other herbicides to control susceptible broadleaves, sedg es 
and grasses in corn. Apply Authority 75 DF Herbicide in conventional tillage or conservation tillage (reduced tillage or no-t illage) 
cropping systems using rates listed in the table above. Authority 75 DF 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 
operation can destroy the herbicide barrier allowing weed escapes to occur. Do not apply to frozen soils or existing snow cove r to 
prevent Authority 75 DF Herbicide runoff from rain or snowmelt that may occur following application. Authority 75 DF Herbicide may 
be tankmixed with other burndown herbicides to control emerged weeds in the fall or residual soil herbicides that are labeled f or fall 
use on corn. Select the correct Authority 75 DF Herbicide 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 75 DF Herbicide 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 75 DF Herbicide may be applied preplant on the soil surface in the spring to control weeds in conventional and conservation 
tillage systems. Authority 75 DF Herbicide 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 cl osed. 
For preemergence applications 14 to 45 days prior to planting, use the mid to high rate in the appropriate rate range for the s oil and 
organic matter type listed in table above. Authority 75 DF Herbicide 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 75 DF Herbicide may be tankmixed with 
insecticides including Mustang® Maxx or Capture® 2EC. If dry conditions persist following preemergence application of Authority 75 
DF Herbicide, a shallow incorporation may be needed to activate the herbicide. If weeds are emerged at the time of Authority 75 DF 
Herbicide application, use a burndown herbicide in conjunction with Authority 75 DF Herbicide as needed. When planting into s oil 
treated preplant with Authority 75 DF Herbicide, minimize soil disturbance to maintain the herbicide barrier on the soil surfac e to 
achieve maximum weed control. Observe all precautions, instructions, and rotational cropping guidelines of each product’s label when 
tank mixing, including all references to potential carryover and crop injury warnings or restrictions.

Authority 75 DF Herbicide Page 14 
 
Preplant Incorporated 
Authority 75 DF Herbicide may be applied as a Preplant Incorporated treatment in the spring prior to planting in reduced and 
conventional tillage corn. Authority 75 DF Herbicide 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 
75 DF Herbicide deeper than 2 inches may result in inconsistent weed control. Use the appropriate rate from table above for the soil 
texture, organic matter, and pH level of the soil. Authority 75 DF Herbicide can be tankmixed with other soil-applied herbici des and 
insecticides labeled for preplant incorporation in corn. Observe all precautions, instructions, and rotational cropping guidel ines of 
each product’s label when tank mixing, including all references to potential carryover and crop injury warnings or restrictions. 
 
Authority 75 DF Herbicide may be applied more than once to the same crop in split or sequential applications to provide season-long 
control of difficult-to- control existing or late emerging weeds.

Preemergence 
Authority 75 DF Herbicide may be applied to succulent lima beans as a preemergence treatment at 4.0 oz/A (0.187 lb ai/A). 
Applications should be made with ground equipment in a minimum of 10 gallons of finished spray per acre. 
 
Precautions 
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 75 DF Herbicide use rates should be reduced in those areas. 
If applying Authority 75 DF Herbicide to course textured soils with less than 1.5% organic matter, wait a minimum of 7 days aft er 
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 Application (MN, ND, SD, MT, CO, NE, WY, ID, WA, OR, WI, MI) 
Authority 75 DF Herbicide may be applied in the fall following crop harvest or in existing fallow fields to control or suppress weeds the 
following season. The Authority 75 DF Herbicide Rotational Crop Guidelines in Table 4 must be followed if crops are planted the next 
season. Authority 75 DF Herbicide should be applied to the harvested crop stubble or soil surface without incorporation. Moisture in 
the form of rain or snow will move and activate the product. Do not mechanically incorporate in the fall or spring after appli cation 
because this activity may destroy the herbicide barrier and weed escapes can occur. Do not apply to frozen soils to prevent Authority 
75 DF Herbicide runoff from rain or snow that may occur following application. Authority 75 DF Herbicide 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 75 DF Herbicide reaching the soil surface, a separate burndown application prior to the appli cation 
of Authority 75 DF Herbicide will be required. Use listed rates of burndown herbicides in combination with Authority 75 DF Herbicide, 
or sequential applications as needed. Higher aerial spray volumes are required when there is a dense weed population or canopy. 
 
Authority 75 DF Herbicide can be tankmixed with other herbicides. Observe all precautions, instructions, and rotational croppi ng 
guidelines of each product’s label when tank mixing, including all references to potential carryover and crop injury warnings o r 
restrictions. 
 
Spring Preemerge Application 
Authority 75 DF Herbicide may be applied as a fallow treatment early in the spring provided the application is made prior to we ed 
emergence, and adequate moisture is available to activate the Authority 75 DF Herbicide. Follow the same use rate specificatio ns 
and application guidelines listed under the Fall Application section above.

PEANUTS 
Southeastern United States Only (AL, GA, MS, NC, SC, VA) 
 
Apply Authority 75 DF Herbicide alone or in combination with other registered herbicides for the control of key grass and broad leaf 
weeds in peanut production. Refer to the information below for specific use directions. Authority 75 DF Herbicide is register ed for 
use on peanuts only in the following states: AL, GA, MS, NC, SC and VA. 
 
Application Instructions 
Authority 75 DF Herbicide may be preplant incorporated (to a depth no greater than 2 inches) up to 14 days prior to planting. 
Alternatively, Authority 75 DF Herbicide may be applied to the soil surface at planting, or within 12 hours after planting. Incorporation 
of Authority 75 DF Herbicide deeper than 2 inches can result in adverse crop response and/or inconsistent weed control. Do not use 
Authority 75 DF Herbicide 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 75 DF Herbicide plus a grass herbicide labeled for 
peanuts is recommended. Under conditions of exceptionally high weed populations or when weeds not controlled by Authority 75 
DF Herbicide are anticipated, the use of suitable post-emergent peanut herbicides is recommended. Broadcast apply the correct 
Authority 75 DF Herbicide use rate from table below, in a minimum of 10 gallons of water per acre of finished spray. Banded 
Authority 75 DF Herbicide application rates must be adjusted in proportion to the broadcast rate.

1Use rates are Authority 75 DF Herbicide oz/A. Specified weeds are controlled in coarse (sand and loamy sand) soils. Medium and fine soils (sandy 
loam, clay loam, clay) or soils with organic matter greater than 1.0% should use the next higher rate in table above. The next higher rate for 5.3 oz/A 
(0.25 lb ai/A) should not exceed 6.3 oz/A (0.3 lb ai/A). 2 Controls initial and several continuing flushes (germinations) of wild poinsettia. 3 Purple nutsedge 
activity is based on preplant incorporated applications of Authority 75 DF Herbicide. Pre-emergence surface applications may p rovide control (>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 75 DF Herbicide 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 75 DF Herbicide application rate, so il 
type (including %OM and pH), timing (after Authority 75 DF Herbicide 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 75 DF Herbicide by aerial application as a preemergence treatment following planting and after dragoff, but pri or to 
potato emergence. Optimum performance can be achieved if Authority 75 DF Herbicide 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 area s without 
irrigation, a shallow incorporation (less than 2 inches) may be needed prior to weed and potato emergence to activate the produ ct. 
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 75 DF Herbicide application, an appropriate burndown herbicide and adjuvants labeled for potatoes may be 
tankmixed with Authority 75 DF Herbicide to control these weeds. Do not apply Authority 75 DF Herbicide if the potatoes have 
emerged from the soil as undesirable crop response may occur. Authority 75 DF Herbicide may be tankmixed with other soil-applied 
herbicides labeled for use in potatoes to improve weed management and increase weed control spectrum. 
 
Apply Authority 75 DF Herbicide in a minimum of 10 gallons of spray by ground application and 5 gallons of spray by air. 
 
 
Chemigation Applications 
 Authority 75 DF Herbicide may be applied to potatoes through sprinkler irrigation systems including center pivot, lateral move , end 
tow, solid set or hand move irrigation systems. Apply Authority 75 DF Herbicide 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 75 DF Herbicide may 
be applied with other products labeled for chemigation use in potatoes. 
 
It is important to note that irrigation with highly alkaline water (high pH) following an Authority 75 DF Herbicide soil applic ation may 
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 75 DF Herbicide 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.

Ground and Aerial Applications 
Apply Authority 75 DF Herbicide in conventional tillage, conservation tillage, reduced tillage or no-tillage cropping systems using rates 
listed in the Authority 75 DF Herbicide Use Rate table above. Authority 75 DF Herbicide 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 75 DF Herbicide 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 75 DF Herbicide may be applied preemergence 
or preplant incorporated. For preplant incorporated applications, incorporation must be uniform and no deeper than 2 inches. Improper 
soil incorporation may result in erratic weed control and/or crop injury. Authority 75 DF Herbicide applied near or after crop emergence 
may cause severe injury to the crop. Authority 75 DF Herbicide can be applied alone or in combination with other labeled soyb ean 
herbicides. Authority 75 DF Herbicide may be followed by labeled postemergence soybean herbicides for increased control of grass 
and broadleaf weeds. Always follow the most restrictive label when tank mixing. When using Authority 75 DF Herbicide in no-ti ll or 
minimum till cropping systems, tank mix with an appropriate burndown herbicide for improved control of existing weeds. 
 
Fall Applications 
 Authority 75 DF Herbicide 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 75 DF Herbicide 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 75 DF Herbicide 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 falling 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 75 DF Herbicide as a fall treatment South of Interstate 70. Applications 
to ridge till production systems 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.

Precautions 
When applying Authority 75 DF Herbicide with other registered herbicides, refer to specific label information on precautions, 
instructions, limitations, application methods and timings, and weeds controlled. 
 
Authority 75 DF Herbicide 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 
discoloration. The duration of these effects are somewhat dependent on the duration of the adverse growing conditions. These effects 
lessen and generally diminish with the return to normal growing conditions. 
 
These Crop Specific Use directions are based upon the interactive effects of Authority 75 DF Herbicide (sulfentrazone) and the primary 
soil and environmental factors, which affect its activity on various weed species and tolerance among crops. The user is requir ed to 
observe the instructions and guidance previously presented under Product Application Instructions, Authority 75 DF Herbicide Product

Fall Applications (For use only in ND, SD, MT, MN, WY, CO, NE, KS) 
Authority 75 DF Herbicide may be applied in the fall as a preplant treatment to control or suppress weeds prior to planting sunflowers 
the following spring. Authority 75 DF Herbicide should be applied to the stubble or soil surface and allow moisture from rain fall 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 75 DF Herbicid e 
runoff from rain or snow melt that may occur following application. Authority 75 DF Herbicide 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 
75 DF Herbicide application, use a burndown herbicide such as glyphosate or paraquat at the full-labeled rate in combination wi th 
Authority 75 DF Herbicide or split application as needed. Select the appropriate rate from table above within the correct soil type and 
organic matter range. When applying Authority 75 DF 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 75 DF Herbicide may be applied preplant on the soil surface in the spring to control weeds in sunflowers. Authority 75 DF 
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. 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 75 DF Herbicide to course textured soils with less than 1.5% organic matter, wait a minimum of 7 days after 
application before planting. Authority 75 DF Herbicide can be tank mixed with other preemerge herbicides labeled for sunflower or 
other crops in subgroup 20B. If dry conditions persist following preemerge application of Authority 75 DF Herbicide, a shallow 
incorporation may be needed to incorporate and activate the herbicide. If weeds are emerged at the time of Authority 75 DF Herbicide 
application, use a burndown herbicide at the full-labeled rate in combination with Authority 75 DF Herbicide or split applicati on as 
needed.

Authority 75 DF Herbicide Page 21 
Preplant Incorporated (PPI) 
Authority 75 DF Herbicide may be applied as a Preplant Incorporated treatment in the spring prior to planting in reduced and 
conventional tillage. Authority 75 DF Herbicide should be shallowly incorporated in the soil no deeper than 2 inches. Incorp orating 
Authority 75 DF Herbicide deeper than 2 inches can result in inconsistent weed control. Use the appropriate rate from table ab ove 
for the soil texture, organic matter, and pH level. Authority 75 DF Herbicide can be tankmixed with other soil-applied herbic ides 
labeled for preplant incorporation in sunflowers or other crops in subgroup 20B.

Precautions 
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 75 DF Herbicide 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 75 DF Herbicide (sulfentrazone) and the primary 
soil and environmental factors, which affect its activity on various weed species and tolerance among crops. The user is requir ed to

Fall Applications (For use only in ND, SD, MT, MN, WY, CO, NE, KS) 
 Authority 75 DF Herbicide may be applied in the fall as a preplant treatment to control or suppress weeds prior to planting sunflowers 
the following spring. Authority 75 DF Herbicide should be applied to the stubble or soil surface and allow moisture from rain fall 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 75 DF Herbicid e 
runoff from rain or snow melt that may occur following application. Authority 75 DF Herbicide 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

Authority 75 DF Herbicide Page 22 
75 DF Herbicide application, use a burndown herbicide such as glyphosate or paraquat at the full-labeled rate in combination wi th 
Authority 75 DF Herbicide or split application as needed. Select the appropriate rate from table above within the correct soil type and 
organic matter range. When applying Authority 75 DF 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 75 DF Herbicide may be applied preplant on the soil surface in the spring to control weeds in sunflowers. Authority 75 DF 
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. 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 75 DF Herbicide to course textured soils with less than 1.5% organic matter, wait a minimum of 7 days after 
application before planting. Authority 75 DF Herbicide can be tank mixed with other preemerge herbicides labeled for sunflower or 
other crops in subgroup 20B. If dry conditions persist following preemerge application of Authority 75 DF Herbicide, a shallow 
incorporation may be needed to incorporate and activate the herbicide. If weeds are emerged at the time of Authority 75 DF Herbicide 
application, use a burndown herbicide at the full-labeled rate in combination with Authority 75 DF Herbicide or split applicati on as 
needed. 
 
Preplant Incorporated (PPI) 
Authority 75 DF Herbicide may be applied as a Preplant Incorporated treatment in the spring prior to planting in reduced and 
conventional tillage. Authority 75 DF Herbicide should be shallowly incorporated in the soil no deeper than 2 inches. Incorp orating 
Authority 75 DF Herbicide deeper than 2 inches can result in inconsistent weed control. Use the appropriate rate from table ab ove 
for the soil texture, organic matter, and pH level. Authority 75 DF Herbicide can be tankmixed with other soil-applied herbic ides 
labeled for preplant incorporation in sunflowers or other crops in subgroup 20B.

Authority 75 DF Herbicide may be surface applied or preplant incorporated (to a depth no greater than 2 inches) from 14 days to 12 
hours days prior to transplanting tobacco. Incorporating Authority 75 DF Herbicide deeper than 2 inches can result in inconsist ent 
weed control. 
 
Broadcast apply the appropriate Authority 75 DF Herbicide rate from table above, in a minimum of 10 gallons per acre of water, to the 
soil prior to transplanting. 
 
Non-Bedded (Fields where raised beds are NOT formed prior to transplanting) 
Perform all accepted cultural practices for land preparation, fertilizer/fungicide incorporation, etc. prior to the application of Authority 
75 DF Herbicide. Once the field has been prepared for planting, Authority 75 DF Herbicide may be surface applied or lightly preplant 
incorporated from 14 days to 12 hours prior to transplanting. 
 
If Authority 75 DF Herbicide is surface applied and it is necessary to remove equipment tracks from the field after application but prior 
to transplanting, any light finishing equipment may be used providing the soil is not disturbed to a depth greater than 2 inches. 
 
If timely cultivations are not performed following a pre-transplant surface application, reduced/unacceptable weed control may occur 
in the drill. 
 
Bedded (Fields where raised beds ARE formed PRIOR to transplanting) 
Apply Authority 75 DF Herbicide to formed beds as a surface application from 14 days to 12 hours prior to transplanting. If it is 
customary to drag/knock down beds prior to transplanting, this procedure must be performed prior to the Authority 75 DF Herbici de 
application. 
 
When incorporating prior to bedding, Authority 75 DF Herbicide must be thoroughly and uniformly incorporated to a depth no greater 
than 2 inches to avoid concentrating Authority 75 DF Herbicide in the bed. 
 
If initial transplanting fails to produce a uniform stand, tobacco may be replanted. DO NOT re-treat field with a second applic ation of 
Authority 75 DF Herbicide, or any other herbicide containing sulfentrazone. DO NOT re-bed. Re-transplant into previously forme d, 
treated beds. 
 
For broad spectrum and optimum grass weed control a grass herbicide application will be required.

Precautions 
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 insure treated soil will not wash or crust 
over tobacco plants.

Early Preplant and Fall Applications (For use only in ND, SD, MT, MN, WY, CO, NE, KS, WI, MI, OR, ID, WA, OR, MT) 
 Authority 75 DF Herbicide may be applied in the fall as a preplant treatment to control or suppress weeds prior to planting the following 
spring. Authority 75 DF Herbicide should be applied to the stubble or soil surface and allow moisture from rainfall or snow t o 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 75 DF Herbicide runoff from rai n or 
snow melt that may occur following application. Authority 75 DF Herbicide 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 75 DF Herbicide application, u se a 
burndown herbicide such as glyphosate or paraquat at the full-labeled rate in combination with Authority 75 DF Herbicide or spl it 
application as needed. Select the appropriate rate from table above within the correct soil type and organic matter range. When 
applying Authority 75 DF 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 75 DF Herbicide may be applied preplant on the soil surface in the spring to control weeds in dry bean and dry peas. 
Authority 75 DF 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. For preemerge applications greater tha n 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 75 DF Herbicide to course textured soils with less than 1.5% organic matter, wait a minimum of 7 
days after application before planting. Authority 75 DF Herbicide 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 75 DF Herbicide, a shallow incorporation 
may be needed to incorporate and activate the herbicide. If weeds are emerged at the time of Authority 75 DF Herbicide application, 
use a burndown herbicide at the full-labeled rate in combination with Authority 75 DF Herbicide or split application as needed. 
 
Preplant Incorporated (PPI) 
Authority 75 DF Herbicide 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 75 DF Herbicide use rates 
for PPI applications are similar to those used in preplant and preemergence applications. Authority 75 DF Herbicide 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

APPLICATION INFORMATION 
Authority 75 DF Herbicide 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 berries to provide preemergence control of weeds listed on this section. 
 
For best control, Authority 75 DF Herbicide should be applied when there are no weeds present or a postemergence herbicide is tank 
mixed to eliminate emerged weeds. 
 
For broadcast applications, a single application of Authority 75 DF Herbicide should be made at 2.7 to 8 oz/A of product (0.125 to 
0.375 lb ai/A). Do not apply more than 8 oz/A of product (0.375 lb ai/A) per twelve-month period. The twelve-month period is 
considered to begin when the initial application of Authority 75 DF Herbicide is applied. 
 
For improved weed management, Authority 75 DF Herbicide can be applied in a tank mixture with other preemergence and 
postemergence burndown herbicides. Refer to the tank mix partner’s labels for additional restrictions, including minimum spray 
volumes and crops in which they are labeled. Burndown herbicides may include, but are not limited to, Aim
®, Shark®, Rage™ D-
Tech, glyphosate, paraquat, Rely ®, and 2,4-D. Do not tank mix with Chateau ® herbicides (flumioxazin) or with other products 
containing sulfentrazone. 
 
When applied as a banded treatment (50% band or less), Authority 75 DF Herbicide may be applied twice per year. Do not apply 
more than 0.5 lb ai/A product on a broadcast application basis per year. 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 Feet 
X Broadcast 
Rate Per Acre = Band Rate Row Width Feet 
 
Band Width Feet 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. 
 
Authority 75 DF Herbicide should only be applied to crops that have been established for one full growing season and are in goo d 
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

Authority 75 DF Herbicide Page 41 
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 through irrigation equipment. 
 
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 75 DF Herbicide is a selective soil-applied herbicide for the control of susceptible broadleaf, grass and sedge weeds found 
in the Permanent Crop Weed listed in this section. Adequate moisture of at least ½ inch is required within 14 days after appli cation 
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 75 DF Herbicide 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. Use the most restrictive label 
limitations and precautions of the tank mix product(s). 
 
Residual weed control may be reduced when Authority 75 DF Herbicide 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 75 
DF Herbicide 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 75 DF Herbicide applied at 8 oz/A of product (0.375 lb ai/A) may provide control or suppression of sedges whether applied 
preemergence or postemergence to the sedges. Postemergence applications to sedges allows Authority 75 DF Herbicide 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 
nonionic surfactant (NIC) at the rate of 0.25% v/v when applying postemergence to sedges. 
 
When applied as directed, Authority 75 DF Herbicide 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 75 DF Herbicide. Apply 2.7 to 4.0 oz/A 
followed by a second application to actively growing nutsedge. Do not exceed the maximum rate of 8 oz/A of product (0.375 lb ai/A) 
per 12 month period. Authority 75 DF Herbicide symptoms on 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. 
 
REPLANTING IN NEW OR ESTABLISHED ORCHARDS AND VINEYARDS 
Delay replanting at least 30 days after Authority 75 DF Herbicide applications when replacing trees and vines in newly planted and 
established orchards and vineyards. Use untreated soil when replanting trees and vines. 
 
Precautions 
These Crop Specific Use directions are based upon the interactive effects of Authority 75 DF Herbicide (sulfentrazone) and the 
primary soil and environmental factors, which affect its activity on various weed species and tolerance among crops. The user i s 
required to observe the instructions and guidance previously presented under Product Application Instructions, Consult university or 
extension weed management specialists for additional information on specific local varieties or cultivars and any other pertine nt
