Product Information Sharpen® herbicide provides both contact burndown and rate-dependent residual preemergence broadleaf weed control (refer to Table 1 and Table 2 for lists, respectively) . It can be used in select field and row crops [alfalfa, chickpea (garbanzo beans), corn (field, seed, silage, sweet, and popcorn), cotton, edible bean, edible pea, field pea, forage grasses (cool-season and warm- season), grass grown for seed, lentils, mint (peppermint and spearmint), rice, small grains, sorghum, southern pea, soybean, vegetable soybean (edamame)], fallow and post- harvest croplands, pasture and rangeland, and in noncropland areas . Sharpen does not control grass weeds and must be used sequentially or tank mixed with a grass herbicide for a complete weed control program . Refer to Crop-specific Information section for recom - mendations on herbicide tank mixtures or sequential programs . Make burndown applications of Sharpen when broadleaf weeds are small and actively growing . An adjuvant is required with Sharpen for optimum burndown activity (refer to Additives section for details) . Burndown activity may be slowed or reduced under cloudy and/or foggy or cooler weather conditions, or when weeds are growing in drought or other stress conditions . When targeting dense weed populations and/or larger broadleaf weeds, use a higher application rate within an application rate range and/or higher spray volumes . Angling nozzles forward (to 45 degrees) may improve penetration of denser weed canopies . Residual preemergence applications of Sharpen must be activated by at least 1/2 inch of rainfall or sprinkler irrigation before weed seedling emergence . When Sharpen is not activated, a labeled postemergence herbicide or cultivation may be needed to control weed escapes . Sharpen may also be used for harvest aid/desiccation in select field and row crops (barley, wheat, and triticale; chia; field corn; dry edible beans; dry peas; oilseeds canola (rapeseed) subgroup 20A; oilseeds cottonseed subgroup 20C; oilseeds sunflower subgroup 20B; and soybean) . Make harvest aid/desiccation applications when crops have reached physiological maturity or according to Extension Service recommendations in the use area . Sharpen is rainfast 1 hour after application . Burndown activity may be reduced if rain or irrigation occurs within 1 hour of application .

8 Mode of Action Sharpen® herbicide is a potent inhibitor of protoporphyrinogen- oxidase belonging to herbicide mode of action Group 14 (WSSA) . Sharpen is rapidly absorbed by roots and foliage . Following inhibition of protoporphyrinogen- oxidase, plant death is the result of membrane damage . Under active growing conditions, susceptible emerged weeds usually develop chlorotic and necrotic injury symp - toms within hours and die within a few days . Susceptible emerging weed seedlings usually die as they reach the soil surface or shortly after emergence . Herbicide Resistance Management While weed resistance to Group 14 herbicides are rela - tively infrequent, populations of resistant biotypes are known to exist . The frequency of resistant biotypes may increase if Group 14 herbicides are used repeatedly in the same field or in successive years as the primary control of the targeted species . If resistant biotypes dominate the weed population, it may result in partial or total loss of control by other Group 14 herbicides . Weeds resistant to Group 14 herbicides may be effectively managed using herbicide(s) from a different group . To aid in the prevention of developing resistant weeds, the following herbicide resistance management principles should be followed where practicable: • Resistance management should be part of a diversified weed control strategy that integrates chemical, cultural, and mechanical (tillage) control tactics . Cultural control tactics include crop rotation, proper fertilizer placement, and optimum seeding rate/row spacing . Start with clean fields using tillage or an effective burndown herbicide program . These practices encourage crop growth and improve competitiveness against weeds . • Clean equipment before moving to a different field to avoid spread of resistant weeds . • Scout fields before application to ensure herbicides and rates will be appropriate for the weeds species and weed sizes present . • Always follow labeled application rate and weed growth stage specifications . • Use sequential programs with preemergence herbicides that provide soil residual control of weeds to reduce early season weed competition and allow for timely in-crop postemergence herbicide applications . • DO NOT rely on a single herbicide site of action for weed control during the growing season . • Avoid application of herbicides with the same site of action more than twice a season . • Use tank mixes or premixes with other herbicides pos - sessing different sites of action that are also effective on the target weeds . • Scout fields after herbicide application to identify areas where weed control was ineffective . • Control weed escapes with herbicides possessing a dif - ferent site of action or use a mechanical control measure . Weed escapes should not be allowed to repro- duce by seed or to proliferate vegetatively . • Contact your Sharpen supplier and/or your local BASF representative to report weed escapes . • Consult your local BASF representative, local or state cooperative extension service, professional consultants or crop advisors, or other qualified authority to determine appropriate actions if you suspect resistant weeds . • Suspected herbicide-resistance 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 on non-controlled plants of a partic - ular weed species; or
• surviving plants mixed with controlled individuals of the same species . Crop Tolerance Crops listed on this label are tolerant to Sharpen when applied according to label directions and under normal environmental conditions . Crop injury may occur under stressful growing conditions (e .g . low soil fertility, seedling disease, extreme hot or cold weather, excessive moisture, high soil pH, high soil salt concentration, or drought) . Severe crop injury will result if Sharpen is applied postemergence (over the top) to any crop (except alfalfa, forage grasses, grass grown for seed, and rice) . Application Instructions Apply Sharpen only before crop emerg ence, except for harvest aid/desiccation uses and postemergence in alfalfa, forage grasses, grass grown for seed, and rice . Application Rates Application rates of Sharpen may vary depending on soil texture and organic matter . Refer to Table 3 for soil texture groups used in this label . Table 3. Soil Texture Groups Coarse Medium Fine Sand Loamy sand Sandy loam Silt Silt loam Loam Sandy clay loam Sandy clay Silty clay Silty clay loam Clay loam Clay Refer to the Crop-specific Information section for spe- cific application rate, timing, and restrictions and limitations by crop and use pattern .

Application Methods and Equipment Sharpen may be applied by ground or air . Thorough spray coverage is required for optimum broadleaf weed control and can be improved with proper adjuvant, nozzle, and spray volume selection . Use and configure application equipment for adequate spray volume, accurate and uniform distribution of spray droplets over the treated area, and to avoid spray drift to nontarget areas . Adjust equipment to maintain continuous agitation during spraying with good mechanical or bypass agitation . Avoid overlaps that will increase rates above use rates specified in this label . Sharpen may be applied using water or sprayable fluid nitrogen fertilizer solutions as the spray carrier . Additionally, Sharpen may be impregnated on and applied with dry bulk fertilizer . Aerial Application Requirements - Helicopter Water Volume. Use 15 or more gallons of water per acre . DO NOT apply more than 2 .0 fl ozs/A of Sharpen (0 .044 lb ai/A of saflufenacil) aerially with helicopter in California . Applicators must follow these requirements to reduce the potential of spray drift to nontarget areas from aerial appli - cation with helicopter: 1 . The distance of the outermost nozzles on the boom must not exceed 75 to 80% of rotor blade diameter . 2 . Use Accu-FloTM .028 nozzles or larger . DO NOT use nozzles producing a smaller droplet size than Accu-Flo  .028 . In California, applicators must select nozzles and pressure that deliver ultra-coarse or larger droplets in accordance with American Society of Agricultural & Biological Engineers Standard 641 (ASABE S641) . 3 . Orient nozzles so spray is released parallel to the airstream . 4 . Without compromising aircraft safety, applications should be made at a height of 10 feet or less above the target vegetative canopy . 5 . DO NOT apply when wind speed is greater than 10 miles per hour, during periods of temperature inver - sions or stable atmospheric conditions . 6 . Avoid potential adverse effects to nontarget areas by maintaining a 50-foot buffer (90-feet in California) between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (grass- lands, forested areas, shelter belts, woodlots, hedgerows, riparian areas, shrub lands, and crop lands) . Aerial Application Requirements - Fixed-wing Aircraft Water Volume. Use 3 or more gallons of water per acre for weed control application . Use a minimum of 5 gallons of water per acre for harvest aid/desiccation application . DO NOT apply aerially with fixed-wing aircraft in California . Applicators must follow these requirements to reduce the potential of spray drift to nontarget areas from aerial application: 1 . The distance of the outermost nozzles on the boom must not exceed 3/4 the length of the fixed wingspan . 2 . Use low-drift nozzles (straight-stream nozzles, D-8 or larger) . DO NOT use nozzles producing a mist droplet spray . 3 . Nozzles must always point backward parallel with the airstream and never point downward more than 45 degrees . 4 . Without compromising aircraft safety, application should be made at a height of 10 feet or less above the crop canopy or tallest plants . 5 . DO NOT apply when wind speed is greater than 10 miles per hour, during periods of temperature inver - sions or stable atmospheric conditions . 6 . Avoid potential adverse effects to nontarget areas by maintaining a 160-foot buffer between the point of direct application and the closest downwind edge of sensi- tive terrestrial habitats (grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas, shrub lands, and crop lands) . Ground Application Requirements Spray Carrier Volume. Use 5 or more gallons of water per treated acre or 20 or more gallons of sprayable fluid nitrogen fertilizer per treated acre for weed control applica - tion . Thorough spray coverage is required for control of emerged broadleaf weeds . High populations and/or variations in size can prevent adequate spray coverage . Controlling fall-germinated weeds in the spring (e .g . horseweed/marestail) also requires thorough spray coverage . Use higher spray volumes (e .g . 15 to 20 gallons of water per acre) in these situations to increase spray coverage and optimize burndown activity . Use a minimum of 5 to 10 gallons of water per acre for harvest aid/ desiccation application .

10 Applicators must follow these requirements to reduce the potential of spray drift to nontarget areas from ground application: 1 . Apply this product using nozzles which deliver medium-to-coarse spray droplets as defined by ASABE standard S-572 and as shown in nozzle manu- facturer’s catalogs . Flat-fan nozzles are recommended for burndown applications while flood-jet type nozzles are recommended for residual soil surface application . Nozzles that deliver coarse spray droplets may be used to reduce spray drift provided spray volume per acre (GPA) is increased to maintain coverage of target (i .e . weeds or soil surface) . DO NOT use nozzles that pro- duce fine (e .g . cone) spray droplets . In California, nozzles must be affixed to spray no higher than 20 inch - es above the spray target (e .g . top of weed foliage) . 2 . Apply this product only when the potential for drift to adjacent nontarget areas is minimal (e .g . when the wind is 10 MPH or less and is blowing away from sensitive areas) . DO NOT apply during periods of temperature inversions or stable atmospheric conditions . 3 . Avoid potential adverse effects to nontarget areas by maintaining a 75-foot buffer (120-foot in California) between the application area and the closest down- wind edge of sensitive terrestrial habitats (grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas, shrub lands, and crop lands) . Ground Application (dry bulk fertilizer) Sharpen® herbicide may be impregnated or coated onto dry bulk granular fertilizer carriers for residual soil surface application . Impregnation or coating may be conducted by in-plant bulk or on-board systems . Perform the mixing operation in well-ventilated areas . Addition of a drying agent may be necessary if the fertilizer and herbicide blend is too wet for uniform application because of high humidity, high urea concentration, or low fertilizer use rate . Slowly add the drying agent to the blend until a flowable mixture is obtained . Drying agents are not recommended for use with on-board impregnation systems . Under some conditions, fertilizer impregnated with Sharpen may clog air tubes or deflector plates on pneu- matic application systems . Mineral oil may be added to Sharpen before blending with fertilizer to reduce plugging . DO NOT use drying agents when mineral oil is used . To avoid separation of Sharpen and mineral oil mixes in cold temperatures, keep mixture heated or agitate before blending with fertilizer . Mineral oil may be used with in-plant blending stations or on-board injection systems . Generally, fertilizer application rates of at least 200 lbs to 700 lbs per acre of herbicide and fertilizer blend provide adequate distribution or coverage of Sharpen across the soil surface . Refer to the Crop-specific Information section in this label for use rates of Sharpen in each crop to be applied on per acre basis when impregnated with fertilizer to create the dry bulk fertilizer blend for applica - tion . Application must be made uniformly to the soil to prevent possible crop injury and offer satisfactory weed control . Impregnated fertilizer spread at half rate and over- lapped for a full rate offers a more uniform distribution . A shallow (less than 2 inches) incorporation is desirable for improved weed control . Deeper incorporation dilutes the herbicide layer near the soil surface and may result in unsatisfactory weed control . To calculate the herbicide rate when using dry bulk fertiliz- er application: fl ozs herbicide per acre x 2000 = fl ozs herbicide per ton of fertilizerpounds fertilizer per acre Cleaning Spray Equipment Clean application equipment thoroughly by using a strong detergent or commercial sprayer cleaner according to the manufacturer’s directions, followed by triple rinsing the equipment before and after applying this product . Spray Drift Management It is the responsibility of the applicator to avoid spray drift at the application site, especially onto nontarget areas . The interaction of many equipment-related and weather-related factors determines the potential for spray drift . The appli- cator and the grower are responsible for considering all these factors when making decisions . The applicator should be familiar with and take into account the information covered in the following spray drift reduction advisory information . Controlling Droplet Size. The most effective way to reduce drift potential is to apply the largest droplets that provide sufficient coverage and control . Volume. Use high flow rate nozzles to apply the highest practical spray volume . Nozzles with higher rated flows produce larger droplets . Pressure. DO NOT exceed the nozzle manufacturer’s specified pressures . For many nozzle types, lower pres- sure produces larger droplets . When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure . Number of Nozzles. Use the minimum number of noz- zles that provide uniform coverage . Nozzle Type. Use a nozzle type designed for the intended application . With most nozzle types, narrower spray angles produce larger droplets . Swath Adjustment. When applications are made with a crosswind, the swath will be displaced downwind . There- fore, on the upwind and downwind edges of the field, the applicator must compensate for this displacement by adjusting the path of the application equipment (e .g . air- craft, ground) upwind . Swath adjustment distance should increase with increasing drift potential (higher wind, smaller droplets, etc .) . Wind. Drift potential is lowest between wind speeds of 3 to 10 mph . However, many factors, including droplet size and equipment type, determine drift potential at any given

11 speed . If applying at wind speeds less than 3 mph, the applicator must determine if: 1 . Conditions of temperature inversion exist, or 2 . Stable atmospheric conditions exist at or below nozzle height . DO NOT make applications into areas of temperature inversions or stable atmospheric conditions . NOTE: Local terrain can influence wind patterns . Every applicator should be familiar with local wind patterns and how they affect spray drift . Wind Erosion. Avoid treating powdery, dry or light sandy soils when conditions are favorable for wind erosion . Under these conditions, the soil surface should first be set - tled by rainfall or irrigation . Additives For optimum burndown or harvest aid/desiccation activity with Sharpen® herbicide, an adjuvant system must be used that includes the following: Adjuvant Rate methylated seed oil1 (MSO) 1 gal/100 gals2 (1% v/v) PLUS PLUS ammonium sulfate (AMS) or urea ammonium nitrate (UAN) 8 .5 to 17 lbs/100 gals (1% to 2% w/v) or 1 .25 to 2 .5 gals/100 gals (1 .25% to 2 .5% v/v) 1 MSO-based adjuvant MUST contain at least 60% methylated seed oil . Poor performance may occur with adjuvants containing less than 60% methylated seed oil . 2 DO NOT use less than 1 pint/A of MSO with low-volume (less than 12 .5 gallons per acre) aerial or ground application . Refer to the Crop- specific Information section for spe- cific adjuvant requirements for certain crop uses . Use of AMS fertilizer is highly recommended when mixing Sharpen with glyphosate-based herbicides . DO NOT use nonionic surfactant (NIS) as a substitute for MSO, or poor performance on broadleaf weeds or for des - iccation will occur . When an adjuvant is to be used with this product, BASF recommends the use of a Chemical Producers and Dis - tributors Association (CPDA) certified adjuvant . DO NOT add acidifying agents to the spray tank when applying Sharpen . Tank Mixing Information It is the pesticide user’s responsibility to ensure that all products in the mixtures are registered for the intended use . Read and follow the applicable restrictions and limita - tions and directions for use on all product labels involved in tank mixing . Users must follow the most restrictive direc- tions for use and precautionary statements of each product in the tank mixture . Sharpen may be tank mixed or applied sequentially with other herbicide products registered for use in any labeled crop found in this label for a broader spectrum of burndown control of emerged weeds and/or residual weed control . Refer to the tank mix product labels to confirm that the respective tank mix products are registered for use on the labeled crop . Read and follow tank mix product labels for application instructions, use restrictions and precautions, and rotational cropping guidance . Tank mixes with contact herbicides (e .g . carfentrazone, paraquat) may reduce the burndown activity of Sharpen . Compatibility Test for Mix Components Before mixing components, always perform a compatibility jar test . 1 . For 20 gallons per acre spray volume, use 3 .3 cups (800 mL) of water . For other spray volumes, adjust rates accordingly . Only use water from the intended source at the source temperature . 2 . Add components in the sequence indicated in Mixing Order using 2 teaspoons for each pound or 1 teaspoon for each pint of label rate per acre . 3 . Always cap the jar and invert 10 cycles between com- ponent additions . 4 . When the components have all been added to the jar, let the solution stand for 15 minutes . 5 . Evaluate the solution for uniformity and stability . The spray solution should not have free oil on the surface, or fine particles that precipitate to the bottom, or thick (clabbered) texture . If the spray solution is not compati- ble, repeat the compatibility test with the addition of a suitable compatibility agent . If the solution is then com- patible, use the compatibility agent as directed on its label . If the solution is still incompatible, DO NOT mix the ingredients in the same tank . Mixing Order Maintain agitation throughout mixing and application until spraying is completed . 1 . Water - Fill tank 1/2 to 3/4 full with clean water and start agitation . 2 . Inductor - If an inductor is used, rinse it thoroughly after each component has been added . 3 . Products in PVA bags - Place any product contained in water-soluble PVA bags into the mixing tank . Wait until all water-soluble PVA bags have fully dissolved and the prod- uct is evenly mixed in the spray tank before continuing . 4 . Water-soluble additives (including dry and liquid fer- tilizers AMS or UAN) 5 . Water-dispersible products (dry flowables, wettable powders, suspension concentrates, or suspo-emulsions) 6 . Water-soluble products 7 . Emulsifiable concentrates (including MSO adjuvants) 8 . Remaining quantity of water If the spray mixture is allowed to settle for any period of time, thorough agitation is essential to resuspend the mix- ture before spraying is resumed . Continue agitation while spraying .

12 Use Restrictions • Maximum seasonal use rate - Refer to Crop- specific Information section for maximum cropping seasonal appli - cation use rates for each crop and use pattern . A cropping season is defined as the period following harvest of the preceding crop through the harvest of the planned or current crop . • Except for labeled harvest aid/desiccation uses and postemergence uses in alfalfa, forage grasses, grass grown for seed, and rice, DO NOT apply Sharpen ® herbicide after crop emergence or severe crop injury will occur . • DO NOT contaminate irrigation ditches or water used for domestic purposes . • DO NOT apply Sharpen through any type of irrigation system (e .g . chemigation) . • Sharpen is not for sale, distribution, or use in Nassau and Suffolk counties in New York State. Crop Rotation and Emergency Replanting Intervals Refer to Table 5 for the proper interval between Sharpen application and planting of rotational crops or replanting after crop failure (because of environmental factors including drought, frost, or hail, etc .) .

Use the lon- ger interval within listed ranges for indicated crops grown on coarse-texture soils with organic matter less than 2 .0% .

• Interval is 0 months in Idaho, Oregon, and Washington . ** Cover crops (winter, spring) may be planted after application of Sharpen , either inter-seeded into the current crop before harvest or after har - vest of the cur rent crop . Depending on the sensitivity of the sown cover crop to Sharpen , stand establishment may be reduced . If cover crops were sown less than 4 months after Sharpen application, DO NOT harvest cover crops as a food or feed crop, and DO NOT allow livestock to graze cover crops . Crop-specific Information Read product information, mixing, application, weeds con - trolled, and adjuvant instructions in preceding sections of the label . Depending on specific crop application directions, Sharpen may be applied for burndown control of emerged broadleaf weeds and/or residual control of ger- minating broadleaf weeds (refer to Table 1 and Table 2 for list of weeds controlled) before crop planting (preplant and/ or preseed) or after planting but before crop emergence (preemergence) and for harvest aid/desiccation uses (refer to Table 10 for list of crops) . For all crop-specific uses in this section, refer to Table 5 for crop rotation intervals . Thorough spray coverage is required for control of emerged broadleaf weeds . High populations and/or variations in size can prevent adequate spray coverage . Controlling fall-germinated weeds in the spring (e .g . horseweed/marestail) also requires thorough spray coverage . Use higher spray volumes (e .g . 15 to 20 gallons of water per acre) in these situations to increase spray cov- erage and optimize burndown activity . Alfalfa Sharpen may be applied in the dormant season or in sea - son between alfalfa cuttings for postemergence broadleaf weed control (refer to Table 1 for list of weeds controlled) in alfalfa production . Before applying Sharpen to alfalfa, verify varietal dorman - cy rating with your local seed company (supplier) to help avoid potential injury to sensitive varieties . Application Method, Rate, and Timing Sharpen may only be applied to established stands of alfalfa (defined as planted in the fall or spring which have gone through a first cutting/mowing) grown for forage and/ or hay production . Sharpen may cause transitory injury to alfalfa (leaf necrosis) under certain conditions, but new growth is nor - mal and yield is typically not reduced . Disease, extremely cold weather, drought, extensive frost heaving, low or high pH, salinity, and other environmental pressures may weak- en alfalfa stands and make the crop more susceptible to herbicidal injury . Dormant-season Application for Burndown Weed Control Apply Sharpen at 1 .0 to 2 .0 fl ozs/A as a broadcast burn - down spray to emerged broadleaf weeds in the dormant season [i .e . when alfalfa is not actively growing in fall (post- harvest), or during winter dormancy] . An adjuvant system is required for optimum broadleaf burndown activity (refer to Additives section for details) . For optimum postemergence control of emerged broadleaf weeds, apply Sharpen in a minimum of 10 gallons of water per acre . Sequential applications of Sharpen may be made within the dormant season if the maximum cumulative amount does not exceed 2 .0 fl ozs/A of Sharpen . Separate sequential dormant season burndown applications by at least 14 days . Timing of Sharpen applications in the dormant season depends on the geographical region where alfalfa is grown . Refer to the following United States map to identify the correct region and states within the region .

14 In Region A, apply Sharpen ® herbicide at least 90 days before harvest or yield reductions of the first cutting may occur .

15 Crop-specific Restrictions • DO NOT apply more than a maximum cumulative amount of 3 .0 fl ozs/A {Alternate text for CA-DPR acceptance of container labeling: 2 .0 fl ozs/A} of Sharpen® herbicide (0 .067 {0 .044} lb ai/A of saflufenacil) per cropping season . • Preharvest Interval (PHI) and Pregrazing Interval (PGI) for alfalfa forage or hay in mixed-stand alfalfa/perennial cool-season forage grasses when Sharpen is applied in dormant season: 28 days . • Preharvest Interval (PHI) and Pregrazing Interval (PGI) for alfalfa forage or hay in mixed-stand alfalfa/perennial cool-season forage grasses when Sharpen is applied in season between cuttings: 21 days . Field Corn (grain, silage), Popcorn, Seed Corn, and Sweet Corn Sharpen may be applied preplant surface, preplant incor- porated, or preemergence to corn for broadleaf weed control (refer to Table 1 and Table 2 for lists of weeds controlled) . Corn in this label refers to field corn (grown for grain or silage), popcorn, seed corn, and sweet corn (pro - cessing varieties only, not including sweet corn grown for seed or fresh market varieties) . Before applying Sharpen to seed corn, processing sweet corn, or popcorn, verify the selectivity of Sharpen on your inbred line or hybrid with your local seed company (supplier) to help avoid potential injury to sensitive inbreds or hybrids . Application Rate Sharpen can be applied as part of a one-pass or planned sequential (two-pass) weed control program . A one-pass weed control program should be used where no cultivation or postemergence herbicide application is anticipated . One-pass application rates for Sharpen when applied alone, in tank mix, or sequentially are in Table 6 for field corn and Table 7 for popcorn and processing sweet corn . Table 6.

16 Application Timing Early Preplant Surface Application (15 to 30 days before planting) Use application rates in Table 6 when making early pre - plant surface applications, using the highest application rate for a given soil texture . Early preplant surface applica- tions are not recommended on coarse soils, in areas where average annual rainfall (or rainfall plus irrigation) typi- cally exceeds 40 inches, or for popcorn or processing sweet corn . Cultivation or a labeled postemergence herbi- cide application may still be required under certain conditions for complete weed control . Early preplant surface applications may be applied as part of a split application program where applications are made as part of the application timings described in this label . However, the cumulative total of sequential application rates must not exceed the maximum labeled rate for a given soil texture . Preplant Surface and Preplant Incorporated Applications (up to 14 days before planting) Sharpen® herbicide can be applied at use rates speci- fied in Table 6 , Table 7 , Table 8 , or Table 9 to the soil surface or incorporated up to 14 days before planting on all soil types . For preplant incorporated application, apply Sharpen and incorporate into the upper soil surface (1 to 2 inches) . Use a harrow, rolling cultivator, field cultivator, or other implement capable of uniform shallow incorporation . Avoid deeper incorporation or reduced weed control may result . Preemergence Surface Application Apply Sharpen at use rates specified in Table 6 , Table 7 , Table 8 , or Table 9 as a broadcast spray to the soil sur - face after planting and before crop emergence . Sharpen must be applied before crop emergence or injury will occur . Burndown plus Residual Weed Control In addition to residual broadleaf weed control at any of the application timings previously described, Sharpen also provides burndown of emerged broadleaf weeds listed in Table 1 . An adjuvant system (refer to Additives section for details) is required for optimum burndown activity . Burndown control of emerged grasses and/or additional broadleaf weeds not listed on the label requires a tank mix with another herbicide (like glyphosate) . Burndown Weed Control Only If limited or no residual broadleaf weed control is desired, Sharpen can be applied at 1 .0 fl oz/A (all soil types) with an adjuvant system any time before corn emergence for burndown of broadleaf weeds listed in Table 1 . A burn- down application of Sharpen can be followed by residual rates of Sharpen (Table 6 , Table 7, Table 8 , or Table 9) or Verdict® herbicide . Separate sequential applications by at least 14 days . However, DO NOT apply more than the cropping seasonal maximum cumulative amount per acre of saflufenacil from all product sources per cropping season . Crop-specific Use in Seed Corn. Apply Sharpen pre- plant surface or preemergence at 1 .0 to 2 .0 fl ozs/A with an adjuvant system for burndown broadleaf weed control in seed corn before crop emergence . DO NOT apply more than 1 .0 fl oz/A on coarse soils . Sequential applications of Sharpen may be made with a minimum of 30 days between applications . DO NOT apply more than a maximum cumulative amount of 4 .0 fl ozs/A of Sharpen per cropping season in seed corn . State-specific Use in California. Apply Sharpen early preplant through preemergence at 2 .0 fl ozs/A with an adjuvant system for burndown broadleaf weed control before crop emergence . Separate sequential applications of Sharpen by at least 14 days . DO NOT apply more than 2 .0 fl ozs/A in a single application . Crop-specific Restrictions • DO NOT apply Sharpen after corn emergence or severe crop injury will occur . • DO NOT apply Sharpen at more than 1 .0 fl oz/A where an at-planting application of an organophosphate (OP) or carbamate insecticide(s) is planned and/or has occurred because severe injury may result . EXCEPTION: Sharpen may be applied when Aztec® 2.1% granular insecticide , Aztec® 4.67 G granular insecticide , or SmartChoice ® 5G granular insecticide is applied at planting as a band, T-band, or in-furrow . Sharpen may be applied with all other classes of at-planting insecticides including neonicotinoid and pyrethroids . • DO NOT apply more than a maximum cumulative amount of 6 .0 fl ozs/A of Sharpen (0 .134 lb ai/A of saflufenacil) per cropping season . • DO NOT apply more than a maximum cumulative amount of 0 .134 lb ai/A of saflufenacil per cropping sea- son in corn from all product sources . • There is no required (preharvest) interval between a pre - plant surface, preplant incorporated, or preemergence application of Sharpen and the harvest of field corn grain, popcorn, seed corn and sweet corn ears . Corn forage, stover, and sweet corn cannery waste may be fed to livestock after harvest . • Corn forage and silage must not be harvested, fed, or grazed sooner than 80 days after application . Crop-specific Precautions • Sharpen use may result in delayed corn emergence and stunting under certain environmental conditions including cool temperatures, excessive rainfall/irrigation, and/or persistent wet soil conditions occurring after application . • Ensure the corn seed row is closed . Soil conditions that cause poor seed furrow closure and coverage may result in delayed corn emergence or stunting .

17 • Sharpen® herbicide applied to processing sweet corn planted at depth of 1/2 inch or less may result in crop injury . Cotton Use Sharpen as an early preplant burndown treatment before planting cotton . Not for use in cotton in California . Application Method, Rate, and Timing Apply Sharpen as a broadcast spray at 1 .0 fl oz/A plus recommended adjuvants (refer to Additives section for details) for control of actively growing broadleaf weeds (refer to Table 1 for list of weeds controlled) . Wait to plant cotton until at least 21 to 42 days and an accumulation of 1 inch of rainfall and/or irrigation occurring after application to avoid crop injury . In areas with average annual rainfall less than 25 inches, the 42-day preplant interval is required after accumulation of 1 inch of rainfall and/or irrigation . DO NOT apply to coarse soils classified as sand with less than 1 .5% organic matter or cotton injury may occur . Crop-specific Restrictions • DO NOT apply more than a maximum cumulative amount of 2 .0 fl ozs/A of Sharpen (0 .044 lb ai/A of saflufenacil) per cropping season . • DO NOT apply Sharpen with other Group 14 herbi - cides (including flumioxazin) as a tank mix or sequential application within 30 days of planting because crop inju - ry may result . Crop-specific Precautions • Use the most restrictive preplant interval with tank mixes of other cotton burndown herbicides . • Cotton gin byproducts may be fed to livestock . Fallow and Postharvest Sharpen may be used as a burndown treatment to con- trol broadleaf weeds at any time of the year during the fallow period following crop harvest and before the follow - ing crop is planted . Sharpen may also be applied for specific postharvest uses to burn down the remaining foli - age after crop harvest . Application Rate and Timing Apply Sharpen as a broadcast burndown spray at 1 .0 to 2 .0 fl ozs/A plus recommended adjuvants (refer to Additives section for details) . For best product perfor- mance, apply when broadleaf weeds are small and actively growing (refer to Table 1 for list of weeds controlled) . Thor- ough coverage of existing weeds is essential and higher spray volumes may be needed for best performance . Sequential applications of Sharpen may be made with a minimum of 14 days between applications; but DO NOT apply more than a maximum cumulative amount of 6 .0 fl ozs/A of Sharpen (0 .134 lb ai/A of saflufenacil) per cropping season . For residual broadleaf weed control, Sharpen may be applied at 2 .0 to 4 .0 fl ozs/A . Specific rotational crop planting intervals must be observed between application of Sharpen and planting of the following crop (see Table 5 for rotational crop planting intervals) .

28 a maximum cumulative amount from sequential applica - tions in mint per cropping season . • Maximum number of applications per year: 2 • There is no required (preharvest) interval between a dor - mant application of Sharpen ® herbicide and the harvest of mint . Crop-specific Precautions • Application to mint stands that have been weakened by age, disease, cold weather, excessive moisture, or other factors that reduce crop vigor may result in crop injury . Mint growing under stress is more susceptible to herbi - cide damage . • Application to mint that is near dormancy break will result in crop injury . Risk of crop injury increases the closer application is to mint dormancy break . • After Sharpen application, temporary crop injury may be observed in the growing season as mint breaks dorman - cy and begins to grow . • The use of Sharpen may result in growth suppression of mint if extreme conditions of high rainfall, high winds, and/or extended periods of water-saturated soil occur right before or soon after mint breaks dormancy . Pasture and Rangeland Sharpen may be applied for broadleaf weed control (refer to Table 1 and Table 2 for list of weeds controlled) in perennial cool-season and warm-season forage grasses grown in pastures or rangeland or Federal Conservation Reserve Program (CRP) land for livestock grazing . Before applying Sharpen to forage grasses, verify the selectivity of Sharpen on your variety with your local seed company (supplier) to help avoid potential injury to sensi- tive varieties . Application Method, Rate, and Timing Apply Sharpen only to established (defined as planted in fall or spring which has gone through a first cutting/mowing) stands of perennial cool-season and warm-season forage grasses . Sharpen may cause transitory injury to forage grasses (leaf necrosis) under certain conditions, but new growth is normal and vigor is not reduced . Disease, extremely cold weather, drought, extensive frost heaving, low or high pH, salinity, and other environmental pressures may weaken grass stands and make the crop more susceptible to herbicidal injury . Dormant-season Application for Burndown and Residual Weed Control in Warm-season and Cool-season Grasses Apply Sharpen at 1 .0 to 2 .0 fl ozs/A as a broadcast burn - down spray to emerged broadleaf weeds in the dormant season [i .e . when grasses are not actively growing in fall (postharvest), during winter dormancy, or in early spring before greenup] . An adjuvant system is required for opti- mum broadleaf burndown activity . For additional residual broadleaf weed control, Sharpen can be applied anytime in the dormant season (as previ - ously described) at 3 .0 to 4 .0 fl ozs/A (except in California) . Sequential applications of Sharpen may be made within the dormant season if the maximum cumulative amount does not exceed 4 .0 fl ozs/A of Sharpen . Apply dormant- season burndown applications sequentially when the first burndown application is made in fall (postharvest) or during winter dormancy, and the second application is in early spring before greenup . Separate sequential dormant-season burndown applications by at least 14 days . Specific Adjuvant Requirements for Dormant- season Application in Warm-season and Cool- season Grasses.

The term “Kixor® Selected” describes soybean varieties that exhibit less sensitivity to Sharpen, but it does not imply any genetic modification to impart tolerance or resistance to the herbicide. Contact your local BASF representative or go to http://www.agproducts.basf.us/products/kixor- selected-soybean-varieties.html for a full list of current Kixor ® Selected soybean varieties. Sharpen may be applied in fall and/or in spring as a preplant surface, preplant incorporated, or preemergence burndown application in conventional-till, reduced-till, or no-till soybeans for broadleaf weed control; refer to Table 1 and Table 2 for list of weeds controlled . An adju- vant system (refer to Additives for details) is required for optimum burndown activity . Use of Sharpen may result in delayed soybean emer- gence and stunting under certain environmental conditions including cool temperatures, excessive rainfall/irrigation, and/or persistent wet soil conditions occurring after application . Not for use on Kixor® Selected soybean varieties in California . Application Method, Rate, and Timing Fall Application Apply Sharpen at 1 .0 to 2 .0 fl ozs/A for burndown broad- leaf weed control after the prior crop is harvested . Application must be made before first killing frost . Fall application can be made to all soil types . Spring Application Apply Sharpen early preplant through preemergence at 1 .0 fl oz/A for burndown broadleaf weed control before crop emergence . Apply Sharpen early preplant through preemergence at 2 .0 fl ozs/A for burndown plus residual broadleaf weed control before crop emergence . Soybean Planting Interval Depending on Sharpen use rate, soil texture, and organic matter, an interval between Sharpen application and planting may be required (see Table 16) or crop injury may occur .

Directions For Use  It is a violation of federal law to use this product in a manner inconsistent with its labeling.  The supplemental labeling and the entire Sharpen® Powered by Kixor® herbicide (henceforth in this label referred to as Sharpen or Sharpen herbicide) container label, EPA Reg. No. 7969-278, must be in possession of the user at the time of application.  Read the label affixed to the container for Sharpen before applying.  Use of Sharpen according to this labeling is subject to the use precautions and limitations imposed by the label affixed to the container for Sharpen. Use Information Sharpen provides contact burndown broadleaf weed control. Refer to Sharpen container label for complete list of weeds controlled. Sharpen does not control

grass weeds and must be used sequentially or tank mixed with a grass herbicide for a complete weed control program. Application Information Application Rates and Timings Apply Sharpen only to dormant established stands (defined as at least one year after planting) of mint (i.e., all Mentha species tops, includes stands harvested for fresh leaves or for stems and leaves processed into oil). All Mentha species tops hereafter referred to as mint. Apply Sharpen at 1.0 to 2.0 fl ozs/A as a broadcast burndown spray to emerged broadleaf weeds in the dormant season [i.e. when mint is not actively growing in fall (postharvest), or during winter dormancy]. An adjuvant system is required for optimum broadleaf burndown activity (refer to Additives section on the product container label for details).

Saflufenacil Group 14 Herbicide

09/10/2024 7969-278

2 For optimum postemergence control of emerged broadleaf weeds, apply Sharpen® herbicide in a minimum of 10 gallons of water per acre.

Sequential applications of Sharpen may be made within the dormant season if the maximum cumulative amount does not exceed 2.0 fl ozs/A of Sharpen. Separate sequential dormant season burndown applications by at least 14 days. Crop-specific Restrictions  DO NOT apply Sharpen to mint that has broken dormancy.  DO NOT apply Sharpen to mint in the first year of growth and establishment.  DO NOT apply more than 2.0 fl ozs/A of Sharpen (0.044 lb a.i./A of saflufenacil) in a single application or as a maximum cumulative amount from sequential applications in mint per cropping season.  Maximum number of applications per year: 2  There is no required (preharvest) interval between a dormant application of Sharpen and the harvest of mint.  Refer to Table 5 on the product container label for crop rotation intervals. Crop-specific Precautions  Application to mint stands that have been weakened by age, disease, cold weather, excessive moisture, or other factors that reduce crop vigor may result in crop injury. Mint growing under stress is more susceptible to herbicide damage.  Application to mint that is near dormancy break will result in crop injury. Risk of crop injury increases the closer application is to mint dormancy break.  After Sharpen application, temporary crop injury may be observed in the growing season as mint breaks dormancy and begins to grow.  The use of Sharpen may result in growth suppression of mint if extreme conditions of high rainfall, high winds, and/or extended periods of water-saturated soil occur right before or soon after mint breaks dormancy. Tank Mixtures It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.
