3 Surface Water Advisory. This product may impact sur- face water quality due to runoff of rainwater . This is especially true for poorly draining soils and soils with shal - low groundwater . This product is classified as having high potential for reaching surface water via runoff for several months or more after application . A level, well-maintained buffer strip between areas to which this product is applied and surface water features including ponds, streams, and springs will reduce the potential loading of saflufenacil, pyroxasulfone, and pyroxasulfones degradation product, [5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)-1H- pyrazol-4-yl]methanesulfonic acid (M1), from runoff water and sediment . Runoff of this product will be reduced by avoiding application when rainfall is forecast to occur with - in 48 hours . Point-source Contamination. To prevent point-source contamination, DO NOT mix or load this or any other pes- ticide product within 50 feet of wells (including abandoned wells and drainage wells), sinkholes, perennial or intermit- tent streams and rivers, and natural or impounded lakes and reservoirs . This setback does not apply to properly capped or plugged abandoned wells and does not apply to impervious pad or dike mixing/loading areas described as follows . Mixing, loading, rinsing, or washing operations performed within 50 feet of a well are allowed only when conducted on an impervious pad constructed to withstand the weight of the heaviest load that may be on or move across the pad . The pad must be self-contained to prevent surface water flow over or from the pad . The pad capacity must be maintained at 110% that of the largest pesticide container or application equipment used on the pad and have suffi - cient capacity to contain all product spills, equipment or container leaks, equipment washwater, and rainwater that may fall on the pad . The containment capacity does not apply to vehicles delivering pesticide shipments to the mix - ing and/or loading site . States may have in effect additional requirements regarding wellhead setbacks and operational containment . Care must be taken when using this product to prevent: • Back-siphoning into wells • Spills • Improper disposal of excess pesticide, spray mixes, or rinsates Check valves or anti-siphoning devices must be used on all mixing equipment .

Product Information SurtainTM herbicide provides rate-dependent residual preemergence control of annual grass weeds, sedges, and annual broadleaf weeds (including biotypes resistant to ACCase inhibitors, ALS inhibitors, HPPD inhibitors, PSII inhibitors, and glyphosate) (refer to Table 1 for list) . It can be used in field corn (grain, seed, silage), fallow, and post- harvest croplands . Periods of dry weather following application of Surtain may reduce herbicidal effectiveness . Residual preemergence application of Surtain must be activated by at least 1/2 inch of rainfall or sprinkler irrigation before weed seedling emergence . When Surtain is not activated, a labeled postemergence herbicide or cultivation may be needed to control weed escapes . Surtain does not con- trol emerged weeds . Herbicidal activity of Surtain may be reduced if excessive trash from the previous crop covers the soil surface during application . Manage trash levels if needed with combine straw shredder/spreaders, earlier burndown of emerged weeds, or light tillage .

Mode of Action Surtain contains two active herbicide ingredients . Saflufenacil is a potent inhibitor of protoporphyrin- ogenoxidase belonging to herbicide mode-of-action Group 14 . Pyroxasulfone is a potent inhibitor of very long chain fatty acid (VLCFA) synthesis, belonging to herbicide mode-of-action Group 15 . Saflufenacil is rapidly absorbed by roots and foliage . Following inhibition of the protoporphyrinogen-oxidase, plant death is the result of membrane damage . Under active growing conditions, sus- ceptible emerging weed seedlings usually develop chlorotic and necrotic injury symptoms within hours and die within a few days . Susceptible germinating weed seeds usually die as they reach the soil surface or shortly after emergence . Pyroxasulfone is a root-and-shoot inhibitor that controls susceptible weed seedlings before or soon after they emerge from the soil . Herbicide Resistance Management For resistance management, Surtain contains both a Group 14 herbicide and Group 15 herbicide . Any weed population may contain plants naturally resistant to

8 Group 14 and/or Group 15 herbicides . The resistant indi- viduals may dominate the weed population if these herbicides are used repeatedly in the same fields . Appropri- ate resistant-management strategies should be followed . To delay herbicide resistance consider: • Avoiding the consecutive use of herbicides that have a similar target-site-of-action on the same weed species . • Using tank mixes or premixes with herbicides from different target-site-of-action groups as long as the involved products are all registered for the same use, have different sites of action, and are both effective at the tank mix or prepack rate on the weed(s) of concern . • Basing herbicide use on a comprehensive IPM (Integrated Pest Management) program including cultural and mechanical methods . • Monitoring treated weed populations for loss of field effi - cacy, and control of escapes with effective alternative herbicides or mechanical methods . • Identify weeds present in the field through scouting and field history and understand their biology . The weed- control program needs to consider all of the weeds present . • Scout fields prior to application to identify the weed spe - cies present and their growth stage to determine if the intended application will be effective . • Scout fields after application to verify the treatment was effective . • Suspected herbicide-resistance weeds may be identified by these indicators: 1 . Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if con - trol is achieved on adjacent weeds; 2 . A spreading patch of non-controlled plants of a partic- ular weed species; or 3 . Surviving plants mixed with controlled individuals of the same species . • If resistance is suspected, treat weed escapes with a herbicide with a different MOA and/or use non-chemical methods to remove escapes, as practicable, with the goal of preventing further seed production . • Report any incidence of non-performance of this product against a particular weed species to your BASF representative . • Contacting your local extension specialist, certified crop advisors, and/or manufacturer for herbicide resistance management and/or integrated weed management directions for specific crops and resistant weed biotypes . Crop Response Crops listed on this label are tolerant to SurtainTM herbicide when applied according to label directions and under normal environmental conditions . Crop injury may occur when application is made under stressful growing conditions (e .g . mechanical injury, drought or excessive moisture for normal crop development, extreme hot or cold temperatures, widely fluctuating temperatures, seed - ling disease, low soil fertility, high soil pH, high soil salt concentration, or other pesticide injury) . Application Instructions Surtain may be applied before or after crop emergence . Application Rate Application rates of Surtain may vary depending on soil texture and organic matter . Refer to Table 2 for soil texture groups used in this label . Table 2.

Refer to the Crop-specific Information section for specific appli- cation instructions (timings, rates, restrictions and precautions) by crop . Preplant Surface Application. Apply Surtain alone or in tank mix within 30 days of planting . If weeds are present at the time of application, use additional weed control methods, for example a tank mix with an appropriate postemergence herbicide(s), to control emerged weeds . Preplant Incorporated (PPI) Application. Incorporate Surtain into the upper (1 to 2 inches) soil surface within 14 days of planting . Deeper incorporation may increase the potential for crop injury and also may result in reduced weed control . Use appropriate equipment for uniform shal- low incorporation, including a field cultivator, harrow, rolling cultivator, or finishing disc . Preemergence Surface Application. After planting and before crop emergence, apply a uniform broadcast treat- ment to the soil surface . Apply Surtain only to a uniform seedbed which is firm and free of clods, cracks, excess trash (previous crop residue), and weed growth . If weeds are present, apply Surtain in a tank mix with an

9 appro priate postemergence herbicide, for example a glyphosate-containing product . Early Postemergence Application. SurtainTM herbicide must be applied and activated before weed seedling emergence or in a tank mixture that controls emerged weeds . Surtain will not control emerged weeds . Weeds that are already emerged at the time of application must be controlled with cultivation, tank mix or sequential application of another herbicide labeled for postemergence control of the target weeds in the crop . Application Methods and Equipment Surtain may be applied by ground or air (fixed-wing air- craft only, DO NOT apply by helicopter) . Thorough spray coverage is required for optimum weed control and can be improved with proper adjuvant, nozzle, and spray volume selection . Use and configure application equipment to provide an adequate spray volume, an accu- rate 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 increase rates above the use rates specified in this label . Surtain may be applied using water or sprayable fluid nitrogen fertilizer solutions as the spray carrier . Additionally, Surtain may be impregnated on and applied with dry bulk fertilizer . Aerial Spray Carrier Volume. Use 3 or more gallons of water per acre . The actual minimum spray volume per acre is determined by the spray equipment used . Use adequate spray volume to provide accurate and uniform distribution of spray particles over the treated area . Ground Spray Carrier Volume. Use 3 or more gallons of water per treated acre or 20 or more gallons of sprayable fluid nitrogen fertilizer per treated acre . Mandatory Spray Drift Management Aerial Applications • DO NOT release spray at a height greater than 10 ft above the ground or crop canopy, unless a greater application height is necessary for pilot safety . • Applicators are required to select a nozzle and pres - sure that deliver a medium or coarser droplet size (ASABE S572) . • When applying by airplane, use low-drift nozzles (straight-stream nozzles, D-8 or larger) . DO NOT use nozzles producing a mist droplet spray . • The boom length must not exceed 75% of the wing- span for airplanes . • Applicators must use 1/2 swath displacement upwind at the downwind edge of the field . • Nozzles must be oriented so spray is directed towards the back of the aircraft, parallel with the airstream, and never point downward more than 45 degrees . (continued) Mandatory Spray Drift Management (continued) Aerial Applications (continued) • DO NOT apply when wind speeds exceed 10 mph at the application site . • DO NOT apply during temperature inversions . Ground Applications • Apply with the nozzle height recommended by the manufacturer, but no more than 3 ft above the ground or crop canopy . • Applicators are required to select a nozzle and pres - sure that deliver a medium or coarser droplet size (ASABE S572) . Flood-jet type nozzles are recommend- ed 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 . soil sur- face) . DO NOT use nozzles that produce fine (e .g . cone) spray droplets . • DO NOT apply when wind speeds exceed 10 mph at the application site . • DO NOT apply during temperature inversions . Buffer Restrictions Aerial Applications To avoid potential adverse effects to nontarget areas, applicators must maintain a 160-foot buffer between the application area and the closest downwind edge of nontarget terrestrial habitats (including grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas, shrub lands, and crop lands) . Ground Applications To avoid potential adverse effects to nontarget areas, applicators must maintain a 75-foot buffer between the application area and the closest downwind edge of nontarget terrestrial habitats (including grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas, shrub lands, and crop lands) . Spray Drift Advisories The applicator is responsible for avoiding off-site spray drift . Be aware of nearby nontarget sites and environmen- tal conditions . Importance of Droplet Size An effective way to reduce spray drift is to apply large droplets . Use the largest droplets that provide target pest control . While applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under unfavorable environmental conditions . Controlling Droplet Size - Ground Boom Volume Volume. Increasing the spray volume so that larger drop- lets are produced will reduce spray drift . Use the highest practical spray volume for the application . If a greater spray

10 volume is needed, consider using a nozzle with a higher flow rate . Pressure. Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size . Spray Nozzle. Use a spray nozzle that is designed for the intended application . Consider using nozzles designed to reduce drift . Controlling Droplet Size - Aircraft Adjust Nozzles Follow nozzle manufacturers recommendations for setting up nozzles . Generally, to reduce fine droplets, nozzles must be oriented parallel with the airflow in flight . Boom Height - Ground Boom Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage . For ground equipment, the boom must remain level with the crop and have minimal bounce . Release Height - Aircraft Higher release heights increase the potential for spray drift . When applying aerially to crops, DO NOT release spray at a height greater than 10 feet above the crop canopy, unless a greater application height is necessary for pilot safety . Shielded Sprayers Shielding the boom or individual nozzles can reduce spray drift . Consider using shielded sprayers . Verify that the shields are not interfering with the uniform deposition of the spray on the target area . Temperature and Humidity When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation . Temperature Inversion Drift potential is high during a temperature inversion . Tem- perature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind . The presence of an inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke generator . Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing . Wind Drift potential generally increases with wind speed . AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray drift . Ground Application (dry bulk fertilizer) SurtainTM 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 Surtain may clog air tubes or deflector plates on pneumatic appli - cation systems . Mineral oil may be added to Surtain before blending with fertilizer to reduce plugging . DO NOT use drying agents when mineral oil is used . To avoid sepa- ration of Surtain and mineral oil mixes in cold temperatures, keep mixture heated or agitated before blending with fertilizer . Mineral oil may be used at 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 for Surtain across the soil surface . Refer to Table 5 in this label for use rates of Surtain to be applied on per acre basis when impregnat- ed with fertilizer to create the dry bulk fertilizer blend for application . Apply uniformly to the soil to prevent possible crop injury and offer satisfactory weed control . Impregnat- ed fertilizer spread at 1/2 rate and overlapped for a full rate offer a more uniform distribution . Use shallow (less than 2 inches) incorporation for improved weed control . Deeper incorporation dilutes the herbicide layer near the soil sur - face and may result in unsatisfactory weed control . To calculate the herbicide rate when using dry bulk fertiliz- er applications: 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 manufacturers directions, followed by triple rinsing the equipment before and after applying this product . Additives Surtain is formulated to provide optimal residual pre- emergence weed control . No additive is needed when Surtain is applied alone . However, several herbicide tank mixes with Surtain may require an adjuvant to improve burndown of emerged weeds . Therefore, depending on the timing of application relative to crop emergence, the following adjuvants may be used with Surtain tank mixes: For applications made before crop emergence (i .e ., pre- plant surface, preplant incorporated, or preemergence): non-ionic surfactant (NIS), crop oil concentrate (COC), high surfactant petroleum oil concentrate/blends (HSPOC), methylated seed oil (MSO), high surfactant methylated oil concentrate (HSMOC), urea ammonium nitrate (UAN) .

11 For applications made after crop emergence (i .e ., early postemergence): NIS at 0 .25% v/v (1 qt/100 gal) optionally with a spray grade ammonium sulfate (AMS) at 8 .5 to 17 lbs/100 gallons of water . If using liquid AMS product, use a rate that delivers an AMS equivalent of 8 .5 to 17 lbs/100 gallons of water . The use of COC or HSPOC may result in temporary crop injury . DO NOT add MSO or HSMOC or UAN to a SurtainTM herbicide spray mix . When an adjuvant is to be used with this product, BASF recommends the use of a Chemical Producers and Distributors Association (CPDA) certified adjuvant . DO NOT add acidifying agents to the spray tank when applying Surtain . Tank Mixing Information It is the pesticide users 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 . Surtain 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 residual weed control and/or control of emerged weeds . 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 applica - tion instructions, use restrictions and precau tions, and rotational cropping guidance . 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 the Mixing Order section using 2 teaspoons for each pound or 1 teaspoon for each pint of labeled use 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 must 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 constant agitation throughout mixing and applica - tion 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 product is evenly mixed in the spray tank before continuing . 4 . Products that are formulated as Wettable Powders, Dry Flowables, and Water Dispersible Granules - Add to tank and allow to fully dissolve . 5 . Water-soluble additives (including dry and liquid fer- tilizers AMS or UAN) 6 . Surtain - Add at this point in tank mix preparation process . 7 . Water-dispersible liquid products (suspension con- centrates and suspo-emulsions, including atrazine-, mesotrione-, topramezone-based products) 8 . Water-soluble products (including certain glyphosate formulated products) 9 . Emulsifiable Concentrates 10 . Adjuvants (including NIS, COC/HSPOC, MSO/HSMOC) 11 . Remaining quantity of water If the spray mixture is allowed to settle for any period of time, thorough agitation is essential to resuspend spray mixture before spraying is resumed . Continue agitation while spraying . Use Restrictions • Maximum use rate - Refer to Crop-specific Information section for the maximum application use rates of Surtain in each crop . • If additional saflufenacil or pyroxasulfone are applied from other product sources, refer to the Crop-specific Restrictions section for each crop use for the maxi- mum cumulative amount per year for each active ingredient . • DO NOT contaminate water used for irrigation or domestic purposes . • DO NOT apply Surtain through any type of irrigation system (e .g . chemigation) . • Surtain is not for sale, distribution, or use in Nassau and Suffolk counties in New York State. Crop Rotation Intervals • Use Table 4 to determine the proper interval between Surtain application and the planting of rotational crops . Determine the rotational crop interval for tank mix prod- ucts and use the most restrictive interval of all products applied .

Depending on the sensitivity of the sown cover crop to Surtain , stand establishment may be reduced . If cover crops are sown for conservation purposes less than 4 months after Surtain application, DO NOT harvest as a food or feed crop, and DO NOT allow livestock to graze cover crops .

13 Emergency Replanting Intervals Field corn (according to application rates in Crop-specific Information) may be replanted immediately after crop fail- ure (because of environmental factors, including drought, frost, hail, etc .) . Crop-specific Information Read product information, mixing, application, weeds con - trolled, and adjuvant instructions in preceding sections of the label . Field Corn (grain, seed, silage) SurtainTM herbicide may be applied preplant surface, preplant incorporated, preemergence, or early post - emergence to corn for residual preemergence control of listed weeds (Table 1 ) . Corn in this label refers to field corn (grown for grain, seed, or silage) . Before applying Surtain to seed corn, verify the selectivity of Surtain on your inbred line or hybrid with your local seed company (suppli - er) to help avoid potential injury to sensitive inbreds or hybrids . Application Rate Use Surtain as a part of a weed control program in field corn either in combination or sequentially with other herbi - cides for a broader spectrum of weed control . Apply Surtain in field corn at the residual rates provided in Table 5 . For use of Surtain in seed corn, refer to Crop-specific Use in Seed Corn section . Table 5.

Text in brackets [ ] is alternate text. Application Timing Surtain may be applied in a single application or in sequential applications . Early Preplant Surface Application (within 15 to 30 days of planting) Use application rates in Table 5 when making early pre- plant surface applications, using the highest application rate for a given soil texture . Early preplant surface applica- tions are not advised on coarse soils, or in areas where average annual rainfall (or rainfall plus irrigation) typically exceeds 40 inches . 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 Application (within 14 days of planting) Apply Surtain at use rates specified in Table 5 as a broadcast spray to the soil surface or incorporated before planting on all soil types . Preemergence Surface Application Apply Surtain at use rates specified in Table 5 as a broadcast spray to the soil surface after planting and before crop emergence . Early Postemergence Application Apply Surtain at use rates specified in Table 5 as a broad- cast spray to field corn at spiking up to the V3 stage (visible third leaf collar) [Alternate text: V1 stage (visible first leaf col- lar) or V2 stage (visible second leaf collar) or V4 stage (visible fourth leaf collar) or V5 stage (visible fifth leaf collar) or V6 stage (visible sixth leaf collar) or V8 stage (visible eighth leaf collar)] . Refer to Additives section for details about adjuvants for applications of Surtain made after crop emergence . Sequential Application If a sequential application program of Surtain is used (e .g . preplant followed by preemeergence application, or preplant or preemergence followed by an early postemer- gence application), the maximum combined rate of Surtain that may be applied in field corn per year is 27 .0 fl ozs/A . Crop-specific Use in Seed Corn. Apply Surtain pre- plant surface, preplant incorporated, preemergence, or early postemergence at 9 .2 fl ozs/A in seed corn across all soil types . Sequential applications of Surtain may be made with a minimum of 30 days between applications . DO NOT apply more than a maximum cumulative amount of 17 .0 fl ozs/A of Surtain per cropping season in seed corn . Before applying Surtain to seed corn, verify the selectivity of Surtain on your inbred line or hybrid with

14 your local seed company (supplier) to help avoid potential injury to sensitive inbreds or hybrids . Crop-specific Restrictions • DO NOT apply SurtainTM herbicide to popcorn or sweet corn . • DO NOT apply more than 17 .0 fl ozs/A of Surtain (0 .083 lb ai/A of saflufenacil, 0 .133 lb ai/A pyroxasulfone) in a single application . • On coarse soil - DO NOT apply more than a maximum cumulative amount of 18 .5 fl ozs/A of Surtain (0 .090 lb ai/A of saflufenacil, 0 .146 lb ai/A of pyroxasulfone) from sequential applications in field corn per year . • On medium and fine soils - DO NOT apply more than a maximum cumulative amount of 27 .0 fl ozs/A of Surtain (0 .132 lb ai/A of saflufenacil, 0 .211 lb ai/A of pyroxasulfone) from sequential applications in field corn per year . • Maximum number of applications per year: 2 • Separate sequential applications by at least 14 days . • If additional saflufenacil is applied from other product sources, DO NOT apply more than the following maxi- mum cumulative amount of saflufenacil from all product sources per year in corn: 0 .134 lb ai/A on all soils . • If additional pyroxasulfone is applied from other product sources, DO NOT apply more than the following maxi- mum cumulative amounts of pyroxasulfone from all product sources per year in corn: 0 .146 lb ai/A on coarse soils, 0 .266 lb ai/A on medium soils, and 0 .266 lb ai/A on fine soils . • There is no required (preharvest) interval between a pre - plant surface, preplant incorporated, or preemergence application of Surtain and the harvest of field corn . Corn forage and stover may be fed to livestock after harvest . • There is no required (preharvest or grazing) interval between an early postemergence application of Surtain made to field corn at V4 stage or earlier and the harvest of field corn . Corn forage and stover may be fed to live- stock after harvest . • Pre-harvest and Pregrazing Interval (PHI, PGI) for corn forage and stover with an early postemergence application of Surtain made to field corn at V5 to V8 stage = 30 days . • DO NOT apply Surtain where an at- planting application of an organophosphate or carbamate insecticide(s) is planned and/or has occurred because severe injury may result . Surtain may be applied with all other classes of at-planting insecticides including neonicotinoids and pyrethoids . EXCEPTION: Surtain 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 infurrow . Crop-specific Precautions • When applied before crop emergence, Surtain applica- tion may result in delayed corn emergence and stunting under certain environmental conditions including cool temperatures, excessive rainfall/irrigation, and/or per- sistent 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 . • Application of this product with other postemergence or residual herbicides may increase the potential for crop injury after corn has emerged . • Early postemergence applications of Surtain may result in crop response symptoms consisting of foliar spotting on emerged leaves . Use of an adjuvant can increase the level of foliar spotting on emerged leaves . Refer to Additives section for more details on adjuvants . • Tank mixing of Surtain with Glufosinate formulations for early postemergence applications is NOT advised as corn injury could result . • Early postemergence applications of Surtain should be made with water as the carrier . Sprayable fluid fertilizer as an herbicide carrier for early postemergence applica - tions in corn can typically cause corn injury up to and including tissue burn (necrosis) . Sprayable fluid fertilizer as a carrier is NOT advised for use with Surtain after crop emergence unless typical fertilizer burn symptoms are acceptable . • Make applications of Surtain promptly after preparing the spray mixture . Avoid use of spray solutions of Surtain which have been allowed to stand or have been stored in application equipment or the mix tank for an extended period of time as corn injury could result . Fallow and Postharvest Croplands Surtain may be used for residual control of weeds at any time of the year during the fallow period following crop har- vest and before the following crop is planted . Application Rate and Timing Surtain may be applied in a single application or in sequential applications . For residual weed control, apply Surtain at 9 .2 to 17 .0 fl ozs/A . Specific rotational crop intervals must be observed between an application of Surtain and planting of the following crop (see Crop Rotation Intervals section for crop rotation restrictions) .
