ENGINEERING CONTROL STATEMENTS 
When handlers use closed systems or enclosed cabs in a manner that meets the requirements listed in the Worker Protection 
Standard (WPS) for agricultural pesticides [40 CFR part 170.240 (d)(4-6)], the handler PPE requirements may be reduced or 
modified as specified in the WPS. 
USER SAFETY RECOMMENDATIONS 
USERS SHOULD: Wash hands before eating, drinking, chewing gum, using tobacco or using the toilet. Remove clothing 
immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. 
ENVIRONMENTAL HAZARDS 
This pesticide is toxic to marine/estuarine invertebrates. Do not apply directly to water, to areas where surface water is present 
or to intertidal areas below the mean high water mark. Drift and runoff may be hazardous to terrestrial and aquatic plants in 
neighboring areas. Do not contaminate water when disposing of equipment washwaters or rinsate. 
Groundwater advisory: This product is known to leach through soil into groundwater under certain conditions as a result of 
label use. Use of this product in areas where soils are permeable, particularly where the water table is shallow, may result in 
groundwater contamination. 
Do not use on coarse soils classified as sand which have less than 1% organic matter. 
Surface water advisory: This product can contaminate surface water through spray drift. Under some conditions, this product 
may also have a high potential for runoff into surface water (pri marily via dissolution in runoff water), for several to many 
months post-application. These include poorly draining or wet soils with readily visible slopes toward adjacent surface waters, 
frequently flooded areas, areas overlying extremely shallow groundwater, areas with in-field canals or ditches that drain to 
surface water, areas not separated from adjacent strafe waters with vegetated filter strips, and areas over-lying tile drainage 
systems that drain to surface waters. 
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining soils and 
soils with shallow ground water. This product is classified as having high potential for reachi ng surface water via runoff for 
several months or more after application. A level, well-maintained vegetative buffer strip between areas to which this product 
is applied and surface water features such as ponds, stream s, and springs will reduce the potential loading of chlorimuron-
methyl rom runoff water and sediment. Runoff of this product wi ll be greatly reduced by avoiding applications when rainfall 
or irrigation is expected to occur within 48 hours. 
 
Windblown Soil Particles 
This product has the potential to move off-site due to wind erosi on. Soils that are subject to wind erosion usually have a high 
silt and/or fine to very fine sand fractions and low organic ma tter content. Other factors whic h can affects the movement of 
windblown soil include the intensity and dire ction of prevailing winds, vegetative cove r, site slope, rainfall, and drainage 
patterns. Avoid applying this product if prevailing local conditions may be expected to result in off-site movement.” 
 
Non-target Organism Advisory 
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, including pollinators, 
in areas adjacent to the treated area. Protect the forage and habitat of no n-target organisms by mini mizing spray drift. For 
further guidance and instructions on how to minimize spray drift, refer to the Spray Drift Management section of this label. 
 
 
PHYSICAL/CHEMICAL HAZARDS 
Do not use or store near heat or open flame. 
 
IMPORTANT 
Injury to or loss of desirable trees or vegetation may result from failure to observe the following: Do not apply or drain or flush 
equipment on or near desirable trees or other plants, or on areas where their roots may extend, or in locations where the 
chemical may be washed or moved into contact with their roots. Do not use on lawns, walks, driveways, tennis courts or similar 
areas. Prevent drift of spray to desirable plants. Do not contaminate any body of water. Keep from contact with fertilizers, 
insecticides, fungicides and seeds during storage. 
Prior to using Authority Broadleaf herbicide, consideration should be given to crop rotation plans. Crops other than 
soybeans may be extremely sensitive to low concentrations of Authority Broadleaf remaining in the soil the next planting season. 
Choice of rotation crop is restricted following application of Authority Broadleaf. (See "ROTATIONAL CROP GUIDELINES" 
for your geographical region.)

3 
 
Thoroughly clean Authority Broadleaf from application equipment immediately after use and prior to spraying crops other than 
soybeans. Failure to remove even small amounts of Authority Broadleaf from application equipment may result in injury to 
subsequently sprayed crops. 
 
DIRECTIONS FOR USE 
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. 
Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protect ed 
handlers may be in the area during app1ication. 
For any requirements specific to your State or tribe, consult the agency responsible for pesticide regulation. 
Proper handling instructions: This product may not be mixed or lo aded within 50 feet of any wells (including abandoned wells 
and drainage wells), sinkholes, perennial or intermittent stream s and rivers, and natural or im pounded lakes and reservoirs. Th is 
setback does not apply to properly capped or plugged abandoned well s and does not apply to impervious pads or properly diked 
mixing/loading areas.

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 e quipment rinse or washwater, 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 to 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 equi pment on the pad. A pad that is covered by a roof of suffici ent 
size to completely exclude precipitation from contact with the pad shall have a minimum containment capacity of 100% of the 
capacity of the largest pesticide container or application equipment of the pad. Containment capacities as described above shal l 
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 ef fect additional requirements regarding wellhead setbacks and 
operational containment. 
Do not apply this product through any type of irrigation system. 
Do not use flood irrigation to apply or incorporate this product. 
Product must be used in a manner which will prevent back siphoning in wells, spills or improper disposal of excess pesticide, 
spray mixtures or rinsates. 
 
AGRICULTURAL USE REQUIREMENTS 
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This Standard 
contains requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of 
agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assistance. It a lso

chemical-resistant gloves made of any waterproof material such as polyethylene or polyvinyl chloride, and shoes plus socks. 
 
WEED RESISTANCE MANAGEMENT 
AUTHORITY BROADLEAF, which contains the active ingredients Sulfentrazone and Chlorimuron-ethyl is a group 14 and 
2 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 a nd/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.

4 
 
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 BROADLEAF 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 contro lled 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 Group 14 and 2 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 and 2 herbicides. 
· Avoid making more than two applications of AUTHORITY BROADLEAF and any other Group 14 and 2 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 pr actices, 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..
 
 
FOR USE ON SOYBEANS ONLY 
Do not apply this product through any type of irrigation system. 
Do not apply aerially. 
Do not feed treated soybean forage or soybean hay to livestock. 
Do not apply Authority Broadleaf more than once per season. 
Do not apply more than 0.375 lb ai/A sulfentrazone per year. 
 
PRODUCT INFORMATION 
Authority Broadleaf Herbicide is a dispersible granule formulation, packaged as a blend in a 17 pound bag or premeasured in a 
25.6 ounce soluble pack, to be mixed with water and sprayed for selective preemergence and preplant incorporated weed control 
in soybeans. When applied according to the instructions on this label, it will control many broadleaf weeds and provide partial 
control of annual grasses. 
Preemergence and preplant incorporated applications of Authority Broadleaf require rainfall or sprinkler irrigation to activate the 
herbicide. Degree of control and duration of effect depend on: rate used, weed spectrum, growing conditions at and following 
time of treatment, soil pH, texture, organic matter, moisture and precipitation. 
This label contains specific use directions for two dis tinct geographical use areas for Authority Broadleaf. The Midwest States 
and the Southern States and are defined under APPLICATION METHODS. This label also contains ge neral use information 
which is applicable to all Authority Broadleaf use geography.

BIOLOGICAL ACTIVITY 
Authority Broadleaf rapidly inhibits the growth of susceptible weeds. Following application of preplant incorporation or 
preemergence treatment, susceptible weeds ma y germinate and emerge, but growth then ceases and leaves become yellow 3 - 5 
days after emergence. Death of leaf tissue and growing point will follow in some species while others will remain green but 
stunted and noncompe titive. Authority Broadleaf provides partial control of some annual grasses when used preplant or 
preemergence but other products may be needed to ensure adequate grass control. 
Poor growing conditions such as excessive moisture, cool temperatures, and soil compaction or the presence of various pathogens 
may impact seedling vigor. Under these conditions the active ingredients in Authority Broadleaf, like other soil applied herbicides, 
can injure soybeans. However, these early injury symptoms are short lived and do not result in yield reductions.

Do not apply Authority Broadleaf after the soybean crop has emerged or severe injury or death of the crop will occur. 
Authority Broadleaf may be applied by any of the methods listed below. These methods apply to both geographical use areas, the 
Midwest States and the Southern States. 
Midwest States: Iowa, Illinois, Indiana, Kansas, Michigan, Missouri, Nebraska, Ohio, Oklahoma, and Pennsylvania. 
Southern States: Alabama, Arkansas, Delaware, Georgia, Kentucky, Louisiana, Maryland, Mississippi, Missouri 
bootheel, New Jersey, North Carolina, South Carolina, Tennessee, Texas, Virginia and West Virginia. 
RAINFALL ACTIVATION 
FOR PREEMERGENCE ACTIVITY 
Best results are obtained if Authority Broadleaf is applied to moist soil and followed by rainfall or irrigation (~1") before w eeds 
germinate. Several small rainfalls of less than 1/4"each are not as beneficial as one large rainfall of ½ -1". On dry soil, mo re 
moisture is required for activation (1-2") before weed emergence. If moisture is insufficient to activate the herbicide, rotar y

7 
 
hoeing or shallow cultivation should be made after emergence of the crop while weeds are small enough to be controlled by 
mechanical means. 
CONSERVATION TILLAGE: 
EARLY PRE-PLANT IN NO-TILL, MINIMUM TILL, OR STALE SEEDBED 
Authority Broadleaf applied Early Pre-plant (no more than 30 days prior to planting, but after the emergence of broadleaf weeds 
and small annual grasses) will provide burndown of many existing weeds as well as normal preemergence broad leaf weed control. 
When used for burndown, Authority Broadleaf is rainfast after one hour. 
For specific burndown claims, adjuvant recommendations, Authority Broadleaf use rates and other tankmixes, see: 
Midwest section- Pre-plant Burndown Directions 
Southern Section - Burndown Directions 
PREPLANT INCORPORATED 
Uniformly incorporate Authority Broadleaf or Authority Broadleaf tankmixes no deeper than the top 1-2" of soil prior to planting 
soybeans. Use equipment suited to proper incorporation into the top 1-2 inches of soil, e.g.: Do-all, field cultivator, or rote rra. 
Authority Broadleaf can be tank mixed with "Command 4EC" and applied preplant incorporated. Refer to the "Command" label 
for specific use instructions. If tankmixed with a grass herbicide such as a Dinitroaniline (DNA) like 'Treflan”, "Sonalan", or 
''Prowl" or an acetanilide such as "Dual", ''Frontier", or "Lasso” follow label instructions for proper incorporation of the gr ass 
herbicide into the top 1 to 2" of soil. Improper soil incorporation can result in erratic weed control or crop injury. If soil is dry, 
rainfall (~1") is required to activate preplant incorporated herbicides such as Authority Broadleaf before weed emergence. 
NOTE: Consult Lasso Dual, Frontier, Prowl , Treflan , Sonalan, or Command labels for additional weeds controlled, use rates an d instructions when Authority 
Broadleaf is used in conjunction with these herbicides.

APPLICATION INFORMATION 
EQUIPMENT / SPRAY VOLUMES 
Ground Application: Apply uniformly by ground equipment with a properly calibrated low pressure (20 to 40 psi) fixed- boom 
sprayer equipped with fan-type nozzles and screens no finer than 50 mesh. Use 10 to 40 gals of water per acre. 
Continuous agitation in the spray tank is required to keep the material in suspension. Avoid overlap and shut off spray booms 
while starting, turning, slowing or stopping, as injury to the crop may result. 
SPRAY TANK PREPARATION 
It is important that spray equipment is clean and free of existing pesticide deposits before using Authority Broadleaf. Follow the 
spray tank cleanout procedures specified on the label of product previously sprayed. If no cleanout procedure is provided, follow 
the cleanout procedure in SPRAYER CLEANUP section of this label. 
Mixing Instructions 
1. Fill the tank 1/4 to 1/3 full of water 
2. While agitating, add the required amount of Authority Broadleaf 
3. Once the Authority Broadleaf is fully dispersed, maintain agitation and continue filling tank with water. (Soluble packs 
should dissolve completely within 5 minutes.) 
4. Authority Broadleaf should be thoroughly mixed with water in the spray tank before adding any other material. 
As the tank is filling and any Soluble Packs have dissolved, add (in order): other herbicide(s), the required spray adjuvant, 
and the nitrogen fertilizer where required. 
5. Apply Authority Broadleaf spray preparation within 24 hours of mixing to avoid product degradation 
6. If the mixture has settled, thoroughly reagitate before using 
7. To improve mixing with liquid fertilizers prepare a slurry in water before adding to spray tank.

13 
 
Additional Use and Handling Information for Authority Broad/eat When Packaged in Water Soluble Packets 
Soluble Packs are contained in waterproof, resealable plastic bags. The individual Soluble Packs will dissolve completely in 
water. Open the outer resealable plastic bag, remove the number of 25.6 ounce Soluble Packs required for the application. 
DO NOT attempt to open or use partial Soluble Packets. 
Soluble Pack Handling Precautions: 
The outer resealable plastic bag is NOT soluble in water. DO NOT place it in the spray tank. 
Excessive handling of the packs, or exposure to moisture, will cause breakage. 
Do not touch the packs with wet hands or place them on wet surfaces. 
Protect unused Soluble Packs by resealing them in the resealable bag. 
SPRAYER CLEANUP 
To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediate following applications 
of Authority Broadleaf as follows:* 
1. Drain tank; thoroughly hose down the interior surfaces of the tank; then flush tank, boom, and hoses with clean water for 
minimum of 5 minutes. 
2. Partially fill the tank with water and add one of the cleaning agents listed below. Complete filling the tank with water, then 
flush the cleaning solution through the boom, hoses, and nozzles. Add water to completely fill th e tank and allow to agitate 
or recirculate for at least 15 minutes. Again, flush the boom, hoses and nozzles, and drain the tank. 
3. Remove the nozzles and screens and clean separately in a bucket containing water and the cleaning agent 
4. Repeat Step 2. 
5. Thoroughly rinse the tank with clean water for a minimum of 5 minutes, flushing water through the boom and hoses. 
NOTE: Use any of the following cleaning agents. Carefully read and follow the individual cleaning agent instructions. 
1. 1. One gallon of household ammonia (contains 3% active) per 100 gallons of water. 
2. Nutra-Sol 
3. Loveland Tank and Equipment Cleaner

5. Chem.-Tank Cleaner and Neutralize 
6. Incide-Out 
7. Tank-Aid 
*A steam-cleaning of fiberglass or stainless steel aerial spray tanks is recommended prior to performing the above cleanout procedure to facilitate the removal of 
any caked deposits. 
 
THE IMPORTANCE OF SOIL PH- ALL STATES 
Soil pH varies greatly, even within the same field. pH variations as much as 2 pH units are common. Composite soil samples 
taken across an entire field, such as those samples taken for soil fertility recommendations, may not detect areas of high pH. Sub-
sampling is recommended for areas likely to have pH values higher than the field average. The following is a non-inclusive lis t 
of potential high pH areas where subsampling is recommended. 
x Where different soil types are evident within a field, sample soil types separately. 
x Where conditions vary within a field, sample areas separately, such as: 
- areas bordered by limestone gravel roads, 
- river bottoms subject to flooding, 
- low areas in hardpan soils where evaporative ponds may occur, 
- eroded hillsides, 
- along drain tile lines, and 
- areas where drainage ditch spoil has been spread. 
x Where lime has not been deeply incorporated, soil may exhibit significantly higher pH values in the upper 3 inches of soil 
Composite soil samples taken at a 6-8 inch depth may not reflect the elevated pH near the su rface. In these cases shallow 
sampling, the upper 3 inches, is advised. 
Determine soil pH by laboratory analysis using a 1:1 soil:water suspension.

MANDATORY SPRAY DRIFT MANAGEMENT 
Ground Boom Applications: 
•Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the ground or crop canopy 
unless making a turf, pasture, or rangeland application, in which case applicators may apply with a nozzle height no more than 4 
feet above the ground. 
• For applications prior to the emergence of crops and target weeds, applicators are required to use a Coarse or coarser droplet 
size (ASABE S572.1). 
• For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE S572.1). 
• Do not apply when wind speeds exceed 10 miles per hour at the application site. 
• Do not apply during temperature inversions. 
 
Boom-less Ground Applications: 
• Applicators are required to use a Medium or coarser droplet size (ASABE S572.1) for all applications. 
• Do not apply when wind speeds exceed 10 miles per hour at the application site. 
• Do not apply during temperature inversions. 
 
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 th e 
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 – Ground Boom 
Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the highest practical spray 
volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher flow rate. 
Ground applicators must use a minimum finished spray volume 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. 
 
Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. 
 
Spray Nozzle – Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift. 
 
Boom height – Ground Boom - Use the lowest boom height that is compatible with the spray nozzles that will provide uniform 
coverage . For ground equipment, the boom should remain level with the crop and have minimal bounce. 
 
Wind - Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. 
Applicators need to be familiar with local wind patterns and terrain that could affect spray drift. 
 
Temperature and humidity - When making applications in hot and dry conditions, use larger droplets to reduce effects of 
evaporation. 
Temperature inversions - Drift potential is high during a temperature invers ion. Temperature inversions are characterized by 
increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. The presence of an 
inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke generator. 
Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke 
that moves upward and rapidly dissipates indicates good vertical air mixing. Avoid applications during temperature inversions. 
 
Sensitive Areas – The pesticide should only be applied when the wind is blowing away from sensitiv e areas (e.g. residential 
areas, bodies of water, known habitat for threatened or endangered species, non-target crops). 
 
Off-Target Movement of Authority Broadleaf Herbicide 
Drift of dilute spray mixtures containi ng Authority Broadleaf Herbicide must be prevented. Observation of the preceding 
environmental conditions, correct application equipment design, calibration and application practices will significantly dimini sh

15 
 
the risk of off-target spray drift. Authority Broadleaf Herbicide can cause significant symptomology by drift on to sensitive crops 
and other plants. This symptomology may manifest initially as di screet, localized spots where contacted by Authority Broadleaf 
Herbicide drift mixtures. Depending on concentration of the sp ray solution and droplets size (effectively determining the dosag e 
of sulfentrazone) and also depending on the inherent sensitivity of the pl ants 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 fru it 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-tar get 
movement or drift of Authority Broadleaf Herbicide 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 Broadleaf Herbicide 
 
Shielded sprayers - Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify 
that the shields are not interfering with the uniform deposition of the spray on the target area. . 
 
Air assisted ground field crop sprayers 
Air assisted field crop sprayers carry dropl ets to the target via a downward directed air stream. Some may reduce the potentia l 
for drift, but if a sprayer is unsuitable for the application and/ or set up improperly, high drift potential can result. It is the 
responsibility of the applicator to determine that a sprayer is suitable for the intended application, is configured properly, and that 
drift is not occurring. 
Note: Air assisted field sprayers can affect product performance by affecting spray coverage and canopy penetration. Consult the 
application equipment section of this label to determine if use of an air assisted sprayer is recommended. 
Boom-less Ground Applications: 
• Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.” 
 
 Handheld Technology Applications: 
• Take precautions to minimize spray drift. 
 
IMPORTANT PRECAUTIONS 
1. Back to back application of ALS or ALS containing herbicides can occasionally result in residual herbicide stacking and 
potential crop injury. Applicator and/or grower is responsible should be aware of previous herbicide use and potential 
interaction it may have with AUTHORITY BROADLEAF application. 
2. All direct or indirect contact (such as spray drift) to other crops or to land scheduled to be planted to crops other than soybeans 
should be avoided. 
3. Ensure the seed furrow is closed and the seed covered on acres treated with AUTHORITY BROADLEAF. 
4. Soybean stunting may occur if excessive rainfall occurs after application but before soybeans emerge. Injury is more prevalent 
under poor drainage or compacted conditions or when soil is sa turated for long periods of time. Soybeans outgrow stunting 
once favorable growing conditions return. 
5. Do not apply AUTHORITY BROADLEAF if there are visible signs of cracking due to soybean emergence, or serious crop 
injury such as but not limited to stand loss may result. 
6. Seedling disease, nematodes, cold weather, deep planting (mor e than 2”), excessive moisture, high salt concentration, or 
drought may weaken soybean seedlings and increase the possibility of crop injury. 
7. Do not tank mix AUTHORITY BROADLEAF with organoph osphate insecticides. Do not apply AUTHORITY 
BROADLEAF within 14 days before or after an application of an organophosphate insecticide, as severe crop injury may 
occur.
