Authority 75 DF Herbicide Page 3 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.

SOIL CLASSIFICATION CHART Table 1 COARSE MEDIUM FINE Sand Sandy clay loam Silty clay loam Loamy sand Sandy clay Silty clay Sandy loam Loam Clay loam Silt loam Clay Silt

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.

The distance of the outermost nozzles on the boom must not exceed ¾ the length of the wingspan or rotor.
Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees.
Observe the regulations of the State where applications are made.
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:

Authority 75 DF Herbicide Page 8 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.

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.

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.

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.

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.

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.

Precautions When applying Authority 75 DF Herbicide to coarse textured soils, it is recommended that growers allow a minimum of 7-14 days from application to planting. Best results are achieved with Authority 75 DF Herbicide when applications are made early preplant an d greater than 14 days before planting.

Under extended periods of dry weather, adequate weed control may not be achieved

Some adverse crop response may occur on coarse textured soils with low organic matter (less than 1.5%) and pH of 7.8 or higher, or on highly eroded soils, or in areas of calcareous outcroppings. Authority 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.

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.
