Shoes plus socks. 2 FOR USE ON SOYBEANS ONLY Do not apply by aerial application. 00 not feed treated soybean forage or soybean hay to live&tock. 00 not apply this product through any type of irrigation system. 00 not apply AUTHORTIY® more than 5.3 ovA per season. AUnIORTIY® herbicide must be used only in accordance with recommendations on this label or in separately published DuPont recommendations. GENERAL INFORMATION AUTHORITY® herbicide is a dispersible grsnule formulation, to be mixed with water and sprayed for selective preemergence weed control in soybeans. PreemeIgence and preplan! incorporated applications of AUTHORITY® require ruinfall 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, soil moisture and precipitation. BIOLOGICAL ACTMTY AUTHORITY® controls weeds througb the process of cell membrane disruption. Weeds emerging from soils treated withAUnIORTIY® become neerotie (wilt and become brown or looked burned) and die shortly after exposure to ligbt. Foliar contact with AUTHORITY® causes rapid desiccation and necrosis of exposed susceptible plant tissues. Poor growing conditions such as excessive moisture. cool temperatures, and soil compaction or 11, presence of various pathogens may impact seedling vigor. Under these conditions, AUTHORTIY®, like other ,oil-applied herbicides, can injure soybeans. However, these early injury symptoms are short lived and do not res"lt in yield reductions. RAINFALL ACTIVATION FOR PREEMERGENCE ACTMTY Best results are obtained if AUTHORTIY® is applied to moist soil and followed by rainfall or inigation before weeds germinate. Several small rainfu\s ofless than 114" each are not as beneficial as one large rainfall of 112 to I". On dry soil, more moisture may be required for activation before weed emergence. If moisture is insufficient t activate the ••• , herbicide. a rotary hoeing or shallow cultivation sho~cl Lt. made after emergence of the crop while weeds are Si nall enougb to be controlled by mechanical means. Whea sufficient moisture is received after dry tl,>nd·.tions, AUTHORITY® will provide control' of susceptible germinating weeds. ' . . ' .

EARLY PRE·PLANT, PREEMERGENCE AND PREPLANT INCORPORATED USE DIRECTIONS APPLICATION METHODS Do not apply DuPontT" AUTHORITY® after the soybean crop has emerged or severe injury or death of the crop will occur. Preplant Incorporated Uniformly incorporate AUTHORITY® or AUTHORITY® taokmixes no deeper tban the top 1-2" of soil prior to planting soybeaos. Use equipment suited to proper incorporation into the top 1- 2 inches of soil, e.g.: Do-all, field cultivator, or roterra. AUTHORITY® can be tank mixed with "Command" 4EC and applied preplant incorporated. Refer to the "Command" label for specific use instructions. If tank-mixed with a gross herbicide such as a Dinitroaniline (DNA) like "Treflan ll , "Sonalan", or "Prowl" or an acetanilide such as "Dual Magnwn", "Dual II Magnum", "Fronti.er", or "Lasso", follow label instructions for proper incorpo~"tion of the grass herbicide into the top I to 2" of soil. Improper soil inCOIPO­ ration can result in erratic weed control or crop injury. If soil is dry, rainiall (-I ") is required to activate preplant incorporated herbicides such as AUTHORI1Y® before weed emergence. NOTE: Consult "Lasso", "Dual Magnum", "Dual Magnum IT', "Frontier", "Prowl", '''Yreflan'', "Sonalan", or "Command" label ... for additional weed'i controlled, use rates and instructions, whenAUTHORITY® is used in col1iunction with these herbicides.

Ck:Ulout procedure to faci!ilnte the removal of any caked deposits. 6 SPRAY DRIFT MANAGEMENT The interaction of many equipment and weather-related factors detemtiues the potential for apray drift. The applicator is responsible for considering all these factors when making application decisions. AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR. IMPORTANCE OF DROPLET SIZE The most effective way to reduce drift potential is to apply large dioplets (> 150 - 200 microns). The best drift management strategy is to apply the largest droplets that provide sufficient coverage and control. The presence of sensitive species nearby, the environmental conditions, and pest pressure may affect how an applicator balances drift control and coverage. APPLYING LARGER DROPLETS REDUCES DRIIT POTENTIAL, BUT WILL NOT PREVENT DRIl'T IF APPLICATIONS ARE MADE IMPROPERLY OR UNDER UNFAVORABLE ENVIRON­ MENTAL CONDITIONS! See Wind, Temperature and Humidity, and Temperature Inversions sections of this label. ContrOlling Droplet Size - General Techniques Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce larger droplets. .Pressure - Use the lower spray pressures recommended for the nozzle. Higher pressure reduces droplet size and does not improve canopy penetration. WHEN HIGHER FLOW RATES ARE NEEDED, USE A HlGHER­ CAPACITY NOZZLE INSTEAD OF INCREASING PRESSURE. Nozzle Type - Uae a nozzle type that is designed for the intended appli.cation. With most nozzle types, narrower spray angles produce larger droplets. Consider using low­ drift nozzles. BOOM HEIGHT Setting the boom at the lowest labeled height (if specified) which provides uniform coverage reduces the exposure of droplets to evaporation and wind. For ground equipment, the boom should remain level with the crop and have minimal bounce. WIND Drift potential increases at wind speeds ofless fum 3 mph (due to inversion potential) or mor:I.1Jl W mph. Hewever, many factors, including droplet sii~ and ,uipmcr.t tye determine drift potential at any gi''''' wwJ spee~. N,'OID GUSTY OR WINDLESS CONDmO;.3. Note: Local terrain can influence'wi;'u p,ttems. i.;cry applicator should be familiar with 10Cai wind pattern:. and how they affect spray drift. TEMPERATURE AND HUMIDITY When making applications in hot and dry conditions, set up equipment to produce larger droplets to reduce effects of evaporation. ~II

TEMPERATURE INVERSIONS Drift pokntiul is high during a temperature inversion. Temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain close to the ground and move laterally in a concentrated cloud. Temperature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. They begin to fann as the sun sets and often continue into the morning. Their presence can be indicated by ground fog; however, if fog is not present, inversions can also be identified by the movement of smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. SHIELDED SPRAYERS Shielding the boom or individual noz.zles can reduce the effects of wind. However. it is the responsibility of the applicator to verify that the shields are preventing drift and not interfering with unifoml deposition of the product. AIR ASSISTED GROUND FIELD CROP SPRAYERS Air assisted field crop sprayers carry droplets to the target via a downward directed air stream. Some may reduce the potential for drift, but if a sprayer is tffisuitable for the application and/or set up improperly, high drift potential can result. It is the responsibility of the applicator to detennine that a sprayer is suitable ror the intended application, is configured properly. and that drift is not occurring. Note: Air assisted field sprayers can affect product perfommnce by affecting spray coverage and canopy penetration. Consult the application equipment section of this label to dctcnnine if usc of an air assisted sprayer is recommended. RESISTANCE MANAGEMENT When herbicides with the same mode afaction arc used repeatedly over several years to control the same weed species in the same field, naturally-occurring resistant weed biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in that field. These resistant weed biotypes may not be adequately controlled. Cultural practices such as tillage. preventing weed escapes from going to seed, and using herbicides with different modes of action within and between crop seasons can aid in delaying the proliferation and possible dominance of herbicide resistant weed biotypes. 7 INTEGRATED PEST MANAGEMENT DuPont recommends the usc of Integrated Pest Managemeot (IPM) pro grants to control pests. This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, cultural. and genetic practices aimed at preventing economic pest damage. Application of this product should be based on IPM principles and practices including field scouting or other detection methods, correct target pest identification, population monitoring, and treating wheo larget pest populations reach locally detennined action thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities to detennine appropriate action treatment threshold levels for treating specific pest/crop or site systems in your area. IMPORTANT PRECAUTIONS

1. Because most crops are highly sensitive to DuPontnt: AUTHORlTY®, all direct or indircct contact (such as spray drift) to crops or to land scheduled to be planted to crops other than soybeans should be avoided. , Do not apply AUTHORITY@ifthere are visible signs of cracking due to soybean emergence, or serious crop injury may result. 3 Seedling disease, nematodes, cold weather, deep planting (more than 2"), excessive moisture, high salt concentration, or drought may weaken soybean seedlings and increase the possibility of crop injury.
