ENVIRONMENTAL HAZARDS This product is toxic to non-target plants. Do not apply directly to water, to areas where surface water is present or to inter tidal areas below the mean high water mark. Do not contaminate water when cleaning equipment or disposing of equipment washwaters. This product has a high potential for runoff after application. P oorly draining soils and soils with shallow water tables are m ore prone to produce runoff that contains this product. A level, well-maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, streams and springs will reduce the potential for contamination of water from runoff. Runoff of this product will be reduced by avoiding applications when rainfall is forecasted to occur within 48 hours. Sound erosion control practices will reduce this products contribution to surface water contamination. Do not apply when conditions favor drift from treated areas. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas. This pesticide is toxic to aquatic invertebrates.

NON-TARGET ORGANISM ADVISORY: This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, including pollinators, in areas adjacent to the treated site. Protect the forage and habitat of non-target organisms by following label directions intended to minimize spray drift. SURFACE WATER ADVISORY: This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining soils and soils with shallow ground water. This product is classified as having high potential for reaching surface water via runoff for several days after application. A level, well-maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, streams, and springs will reduce the potential loading of thiencarbazone-methyl from runoff water and sediment. Runoff of this product will be reduced by avoiding applications when rainfall or irrigation is expected to occur within 48 hours.

Ground Water Advisory The active ingredients in this product have properties and char acteristics associated with chemicals detected in ground water. This chemical may leach into ground water if used in areas where soils are permeable, particularly where the water table is shallow. SC 547 Herbicide contains Tembotrione, which is known to leach th rough soil into ground water under certain conditions as a res ult of labeled use.

PRODUCT INFORMATION SC 547 Herbicide may be used for preemergence or postemergence selective control of annual grasses and broadleaf weeds in field corn, field corn grown for silage, white corn, seed corn, sweet corn and popcorn. If SC 547 Herbicide is applied as a preemergence application, do not apply SC 547 Herbicide as a postemergence application. Dry weather conditions following the preemergence application of SC 547 Herbicide may reduce weed control. When SC 547 Herbicide is applied postemergence, growth of susceptible weeds ceases within hours after application. Symptoms on susceptible weed species progress from stunted growth to yellowing and bleaching to necrosis resulting in eventual plant death generally within 7 to 14 days after application. SC 547 Herbicide also contains a safener, which greatly reduces or prevents the temporary yellowing or stunting crop response associated with the contained herbicide chemistries when applied postemergence. If symptoms appear, corn quickly outgrows the effect and develops normally.

SC 547 Herbicide is effective in controlling glyphosate-, triazine-, plant growth regulant-, PPO- or ALS- resistant weed populations.

MANDATORY SPRAY DRIFT

Ground Boom Applications: x User must only apply with the release height recommended by the manufacturer, but no more than 3 feet above the ground or crop canopy. x Applicators are required to use a medium or coarser drople t size in accordance with the most current version of the American Society of Agricultural & Biological Engineers Standard 572 (ASAE S572). x Do not apply when wind speeds exceed 15 miles per hour at the application site. x Do not apply during temperature inversions.

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 • 9ROXPH- Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the highest practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher flow rate. • Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. • Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift.

BOOM HEIGHT Ground Boom For ground equipment, the boom should remain level with the crop and have minimal bounce.

TEMPERATURE AND HUMIDITY When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.

TEMPERATURE INVERSIONS Drift potential is high during a temperature inversion. Temperature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. The presence of an inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. Avoid applications during temperature inversions.

ROTATIONAL CROP RESTRICTIONS Rotational crops vary in their response to low concentrations of SC 547 Herbicide remaining in the soil. The amount of SC 547 Herbicide that may be present in the soil depends on soil moisture, soil temperature, application rate, elapsed time since application an d other environmental factors. When SC 547 Herbicide is used in combination with other products, always follow the most restrictive rot ational crop requirements. The following rotational crops may be planted after applying SC 547 Herbicide in corn:

3 When soil pH is 7.5 or above crop plant back should be delayed to 18 months, and to 24 months for crops listed in the 18 month interval above.

  1. Rotation to sorghum should be delayed to the next interval when the total seasonal rate of SC 547 Herbicide exceeds 3.0 fl oz per acre or the total from all sources of Thiencarbazone-methyl exceeds 0.014 pounds of active ingredient per acre per season.

5 For a planned crop rotation to spring seeded alfalfa/spring oats following corn, make only one application of SC 547 Herbicide to the corn crop and do not exceed a total of 3 fl oz of product/A per 365 day period. The interval between application of SC 547 Herbicide to corn and spring planting of the alfalfa/spring oats rotational crop must be equal to or longer than 18 months when the total thiencarbazone-methyl application rate from all sources exceeds 0.013 lb ai/A per season or when soil pH is 7.5 or above, crop plant back should be delayed to the next interval.

6All other crops may be seeded only after the completion of a successful bioassay after a SC 547 Herbicide application. Refer to the “Field/ small scale bioassay” section.

Cover Crops Use of cover crops as a means of soil improvement, erosion control, weed and/or insect suppression, etc., following harvest of corn in the fall is increasing. Planting of cover crops in fields treated with SC 547 Herbicide is allowed as long as these cover crops are not grazed by livestock nor harvested for food. Cover crops are to be tilled under or chemically controlled with burndown herbicides in the spring. Cover crops can be planted within 90-120 days after application of SC 547 Herbicide. However, all potential cover crops have not been evaluated for tolerance to SC 547 Herbicide and significant injury may occur. Prior to seeding a cover crop, complete a successful field/ small scale bioassay to provide an indication of the level of tolerance to the prior SC 547 Herbicide application. Refer to the “Field/ Small Scale Bioassay” section. If used in tank mixtures with other herbicides, always follow the most restrictive label.

Field/Small Scale Bioassay A field/ small scale bioassay must be completed before rotating to a cover crops other than those specified in the “Rotational Crop Restrictions” section of this label. To conduct an effective field bioassay, grow strips of the crop(s) you intend to grow the following season in a field previously treated with SC 547 Herbicide. The test strip should be placed in a controlled area and should include low areas and knolls, and include variations in soil such as type and pH. Crop response to the bioassay will determine if the crop(s) grown in the test strips can be grown safely in the areas previously treated with SC 547 Herbicide. For an effective small scale bioassay, collect uniform samples of all soil types from the SC 547 Herbicide - treated field (see example above for types of soil in the sample) and place the soil into a sturdy container. Plant the desired cover crop into the soil, apply water and place the container in a warm, sunny area to allow germination and growth of the crop. Monitor growth of the cover crop over a three to four week period. If the cover crop emerges and grows normally, the risk to establish and grow the cover crop in the SC 547 Herbicide -treated field should be tolerable.

Appropriate resistance-management strategies should be followed.

To delay herbicide resistance take one or more of the following steps: ‡5RWDWHWKHXVHRI6&+HUELFLGHRURWKHUURXSDQGURXSKHUELFLGHVZLWKLQDJURZLQJVHDVRQVHTXHQFHRUDPRQJJURZLng seasons with different herbicide groups that control the same weeds in a field. • Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target weed species is available, use the less resistance-prone partner at a rate that will control the target weed(s) equally as well as the more resistance-prone partner. Consult your local extension service or certified crop advisor if you are unsure as to which active ingredient is currently less prone to resistance. • Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information related to herbicide use and crop rotation, and that considers tillage ( or other mechanical control methods), cultural ( e.g., higher crop seeding rates; precision fertilizer application method and timing to favor the crop and not the weeds), biological (weed competitive crops or varieties) and other management practices. • Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of possible herbicide resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) surviving plants mixed with controlled individuals of the same species. If resistance is suspected, prevent weed seed production in the affected area by an alternative herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed. • If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switch to another management strategy or herbicide with a different mode of action, if available. • Contact your local extension specialist or certified crop advisors for additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes. • For further information or to report suspected resistance contact Bayer CropScience at 1-866-99BAYER (1-866-992-2937). You can also contact your pesticide distributor or university extension specialist to report resistance.

USE RESTRICTIONS

  1. DO NOT apply this product by air or through any type of irrigation system.
  2. DO NOT apply more than two applications of SC 547 Herbicide to field corn in one growing season.
  3. DO NOT apply more than one application of SC 547 Herbicide to sweet corn in one growing season.
  4. Do not apply SC 547 Herbicide to corn that exhibits injury from previous herbicides applications.
  5. DO NOT apply SC 547 Herbicide within 45 days of grazing livestock or harvesting corn forage.

USE PRECAUTIONS

  1. Plant corn at least 1 ½ inches deep. Corn seed must be completely covered with soil and furrow firmed.
  2. Apply SC 547 Herbicide spray mixtures within 24 hours of mixing to avoid product degradation.
  3. SC 547 Herbicide is rain fast 1 hour after application to most weed species.
  4. Allow at least 14 days between applications of SC 547 Herbicide.
  5. If SC 547 Herbicide is applied as a preemergence application, do not apply SC 547 HERBICIDE as a postemergence application.
  6. Weed control may be reduced if the application is made when weeds are dust covered or in the presence of heavy dew, fog, and mist/rain or when weeds are under stress due to drought.
  7. Avoid spray drift from treated areas. Refer to the Spray Drift Management section of this label for additional information.
  8. Tank contamination can cause severe damage to other crops. Careful management of tank clean out is required. See Tank Cleanout section for complete instructions.
  9. Field corn (yellow dent) can be planted immediately after an application of SC 547 Herbicide. Other rotational crops can be planted as instructed in the rotational crop restrictions portion of this label.
  10. Postemergence applications of SC 547 Herbicide should be made in water as the carrier. Sprayable fluid fertilizer as a herbicide carrier for postemergence applications in corn can typically cause corn injury up to and including tissue burn (necrosis). Sprayable fluid fertilizer as a carrier is not recommended for use with SC 547 Herbicide after crop emergence unless typical fertilizer burn symptoms on the crop are acceptable.
  11. If a preplant/preemergence HPPD containing product has been applied, do not apply a solo application of SC 547 Herbicide in the same season; always include an additional effective mode of action herbicide(s) as a tank mix partner.

Directed Postemergence Applications Directed postemergence applications of SC 547 Herbicide can be made to corn up to and through the seven (7) leaf collar stage of JURZWK 9WKHILUVWOHDIKDVDURXQGHGWLS 'RQRWDSSO\WRFRUQWKDWLVPRUHPDWXUHWKDQ9VWDJHRIJURZWK LHPRUHWKan 7 visible OHDIFROODUV $SSOLFDWLRQVRI6&+HUELFLGHRQFRUQWKDWLV9XSWKURXJK9LQFUHDVHVWKHSRWHQWLDOIRUDQDGYHUVHFURSresponse. The risk may be greatly reduced, but not eliminated, by using drop nozzles properly placed between corn rows to optimize coverage on the weeds and minimize spray contact in the whorl and the leaf axles of the corn stalks. Use drop nozzles and appropriate spacing to direct spray below the corn whorl and upper leaves. The top of the target weed canopy must be sufficiently below the whorl and upper leaves of the crop to permit this application and provide adequate spray coverage. The height differential required between the crop and weed canopy will depend on the specific equipment used.

MIXING INSTRUCTION Application with water or liquid fertilizer as a carrier: SC 547 Herbicide must be applied with clean and properly calibrated equipment. Prior to adding SC 547 Herbicide, ensure that the spray tank, filters and nozzles have been thoroughly cleaned and that agitation system is properly working.

  1. Fill spray tank with 50% of the required volume of water, or liquid fertilizer prior to the addition of SC 547 Herbicide and begin agitation.
  2. Agitate the SC 547 Herbicide product container by shaking, circulating, or stirring prior to adding the herbicide into the s pray tank.
  3. Add the appropriate amount of SC 547 Herbicide slowly to the spray tank or mixing system and ensure complete dispersion. Maintain and ensure thorough dispersion and sufficient agitation during both mixing and spraying.
  4. If tank mixing with another pesticide, add the tank mix product next.
  5. Add nitrogen fertilizer.
  6. Add the adjuvant.
  7. Fill the spray tank with balance of water needed.

If ammonium sulfate (AMS) is the nitrogen fertilizer source, it is preferred that the AMS go into the tank after the SC 547 Herbicide and before other tankmix partners or adjuvants.

Compatibility If SC 547 Herbicide is to be tank mixed with other pesticides, compatibility must be tested prior to mixing. To test for compatibility, use a small container and mix a small amount (0.5 to 1qt) of spray solution, combining all ingredients in the same ratio as the anticipated use. If any indications of physical incompatibility develop, do not use this mixture for spraying. Indications of incompatibility usually occur within 5-15 minutes after mixing. If the mixture balls-up, or forms flakes, sludges, gels, oily films or layers, or other precipitates, it is not compatible and the tank mix combination should not be used.

Tank Cleanup Procedure Cleaning Equipment After SC 547 Herbicide Application Special attention must be given to cleaning equipment before spraying a crop other than corn. Mix only as much cleaning solution as needed.

  1. Remove, dump and clean main sump and boom strainers in a standard commercial tank cleaner solution.
  2. Disassemble nozzle bodies including screens, gaskets, and diaphragm caps and clean in a standard commercial tank cleaner solution.
  3. Rinse walls of tank and all surfaces of tank to remove visible residue.
  4. Reassemble nozzles and strainers.
  5. Flush the system with clean water.
  6. Add 25-50 gallons of water to spray tank. Add 1-2 gallons of household bleach to spray tank (1 gallon bleach for 25 gallons water). Start agitation in the sprayer and re-circulate the bleach-containing solution for 15 minutes.
  7. Spray out the bleach-containing solution until the tank is empty.
  8. Rinse machine with clean water.
  9. Dispose of all rinsate in an appropriate manner.

SPECIFIC CROP USE DIRECTIONS )LHOG&RUQ)LHOG&RUQ*URZQIRU Silage, Sweet Corn and Popcorn

PREEMERGENCE USE x This product can be used as a preemergence application in field corn, field corn grown for silage and specialty corns such as white corn, seed corn, sweet corn and popcorn for the control of annual broadleaf and grass weeds. x Do not apply SC 547 Herbicide on coarse textured soils containing less than 2.0% organic matter or crop injury may occur. x Apply SC 547 Herbicide preemergence at 3-6 fl oz of product/A pe r application (the maximum rate for sweet corn is 3 fl oz per acre per 365 days). In most cases, SC 547 Herbicide alone will not provide season-long residual grass and broadleaf weed control and should be either tank mixed with additional registered residual preemergence herbicide (see Preemergence tank mixture section) or be followed by a planned postemergence herbicide application program. x If SC 547 Herbicide is applied as a preemergence application, do not apply SC 547 Herbicide as a postemergence application. x In preemergence situations where weeds have emerged prior to corn emergence, a tank mixture of SC 547 Herbicide with crop oil concentrate (COC) is recommended for burndown of labeled weeds which are 3 inches or less in height. When weeds are greater the 3 inches in height or weeds not controlled by SC 547 Herbicide are present, the addition of a burndown herbicide (e.g., Liberty ® 280 SL Herbicide, *UDPR[RQH® Extra, glyphosate, or 2,4-D) is recommended. The addition of atrazine in the tank mixture will further improve control of certain weeds.

POSTEMERGENCE USE x This product can be used as a postemergence application in field corn, field corn grown for silage and specialty corns such as white corn, seed corn, sweet corn and popcorn for the control of annual broadleaf and grass weeds. x Apply SC 547 Herbicide at 3 fl oz of product/A per application. Always add the appropriate adjuvants to the spray tank (see Spray Additives Section of this label). x Applications of SC 547 Herbicide at rates less than 3 fl oz of product/A post emergence may result in incomplete weed control and reduction in residual activity. x Follow all precautions and warnings for using ALS-inhibiting or Sulfonyl urea (SU) herbicides on a particular hybrid/variety. x Corn hybrids and certain male pollinators within blended corn varieties vary in their response to SC 547 Herbicide. Not all hybrids or male pollinators within blended corn varieties have been tested for sensitivity to SC 547 Herbicide. You should consult with your seed provider or other knowledgeable agricultural professionals for advice on tolerance of hybrids or varieties containing male pollinator lines before applying SC 547 Herbicide. If the tolerance of a hybrid or variety containing male pollinator lines is not known, you should apply SC 547 Herbicide to a small area to first determine if the hybrid is tolerant prior to spraying large acreages of that hybrid. x $SSO\6&+HUELFLGHWRILHOGFRUQFRUQJURZQIRUVLODJHDQGZKLWHFRUQIURPWKH9FRUQJURZWKVWDJHXSWRLQFKHVWDOO. Do not apply if field corn, corn grown for silage and white corn more than 20 inches tall or exhibiting seven (7) or more leaf FROODUV 9 ZKLFKHYHULVPRUHUHVWULFWLYHBroadcast applications for corn grown for seed, sweet corn and popcorn are UHFRPPHQGHGIURPWKH9WR9JURZWKVWDJHV(5 leaf collars). x While SC 547 Herbicide has a wide application window, research has shown best results are obtained when applications are made early postemergence (row n go) when corn and weeds are small. Target applications to corn generally less than 12 inches tall for best overall performance. SC 547 Herbicide will affect weeds that are larger than the recommended height; however it may result in incomplete weed control. x Do not exceed a total of 6 fl oz of product/A of SC 547 Herbicide per 365 days for all corn types except sweet corn.

x For sweet corn, do not exceed 3 fl oz per acre per 365 days of SC 547 Herbicide. x Do not exceed a total of the following components per acre per 365 days from all sources: 0.04 pounds Thiencarbazone- methyl, 0.164 pounds Tembotrione. Tembotrione with the exception as listed below for a planned crop rotation to spring seeded alfalfa/spring oats following corn. x For a planned crop rotation to spring seeded alfalfa/spring oats following corn , make only one application of SC 547 Herbicide to the corn crop and do not exceed a total of 3 fl oz of product/A per 365 day period. The interval between application of SC 547 Herbicide to corn and spring planting of the alfalfa/spring oats rotational crop must be equal to or longer than 10 months. Refer to the “ROTATIONAL CROP RESTRICTIONS “section of this label for additional information. For this specific crop rotation, do not exceed a total of the following components per acre per 365 days from all sources: 0.013 pounds Thiencarbazone-methyl, 0.164 pounds Tembotrione

SPRAY ADDITIVES SC 547 Herbicide is a suspension concentrate that requires the use of an external adjuvant and a nitrogen fertilizer source to achieve optimum weed control when weeds are present at time of application. For specific adjuvant recommendations with tank mixtures, see the Tank Mix Recommendations section of this label.

Crop Oil Concentrate Use Crop Oil concentrate (COC) at 1 gallon per 100 gallons of water (1% v/v). COC should contain at least 80% crop oil and 10% emulsifier or greater. The use of adjuvants such as non-ionic surfactants or refined vegetable oils will result in unacceptable or erratic weed control. With SC 547 Herbicide, the addition of high surfactant oil concentrate (HSOC) at recommended rates may substitute for the addition of COC. MSO (0.5% v/v) may also be substituted for COC when plants are growing under adverse conditions such as drought stress, low humidity, etc.

Ammonium Nitrogen Fertilizer Use 1.5 qt/A of a high-quality urea ammonium nitrate (UAN) or 1.5 lb/A or 8.5 lb per 100 gallons with a minimum of 1.5 lb/A of a spray- grade ammonium sulfate (AMS). Use UAN under conditions of low relative humidity for greater weed control.

TANK MIX RECOMMENDATIONS Certain tank mixes may aid in the performance of SC 547 Herbicide. Tank mixtures with SC 547 Herbicide are not limited to the listed tank-mix partners. When using SC 547 Herbicide in tank mix combinations, read and follow all parts of tank mix partner labels. Follow the directions of the most restrictive tank mix partner label.

Postemergence Tank Mixtures Atrazine An application of SC 547 Herbicide at 3 fl oz/A in combination with atrazine at 0.5 lb ai/A will increase the speed of control, weed spectrum and consistency of control for most labeled species. Do not use atrazine if corn is greater than 12 inches tall. Include adjuvants as described under the Spray Additives section of this label.

Roundup Brand Agricultural Herbicides SC 547 Herbicide at 3 fl oz/A can be tank mixed with Roundup brand agricultural herbicides for use on field corn hybrids with Roundup Ready 2 Technology. SC 547 Herbicide will enhance broadleaf control, combat glyphosate-resistant weeds and reduce glyphosate induced weed shifts. SC 547 Herbicide should be added to the water in the tank and dispersed first prior to adding Ammonium Sulfate (AMS), glyphosate or any other pesticide or adjuvant. The addition of glyphosate-compatible oils such as HSOC are recommended to optimize weed control in combination with SC 547 Herbicide whenever glyphosate-resistant weed populations such as waterhemp, palmer amaranth, etc., are present.

Buctril® and equivalent bromoxynil products To aid in the control of certain broadleaf weeds (e.g. ragweeds), SC 547 Herbicide at a rate of 3.0 fl oz/A can be tank mixed with Buctril at a rate up to 6 fl oz/A. Buctril can be used in place of atrazine in corn that is greater than 12 inches tall, which is the corn height limit for the use of atrazine. The use of crop oil concentration (COC) plus an ammonium nitrogen fertilizer as described in the Spray Additives section of this label is recommended with tank mixture of SC 547 Herbicide and Buctril.

Dicamba-containing products SC 547 Herbicide at a rate of 3 fl. oz/A can be tank mixed with Diflexx® or other dicamba-containing products for improved broadleaf weed control.

Acetamide-containing products SC 547 Herbicide at 3 fl oz/A can be tank mixed with certain water-based acetamide or acetamide-containing products such as Degree Xtra and Warrant for improved residual control of certain hard-to-control, long germination window weeds such as waterhemp, Palmer amaranth. Do not use Degree Xtra if corn is greater than 11 inches tall. Include adjuvants as described under the Spray Additives section of this label.

Preemergence Tank Mixtures SC 547 Herbicide may to be used in tank-mixture with atrazine to improve spectrum and consistency of weed control wherever atrazine use is permitted and appropriate.

INSECTICIDE INTERACTION INFORMATION Soil Applied Insecticide Interaction Information When SC 547 Herbicide and organophosphate (OP) insecticides are applied to corn, the degradation of SC 547 Herbicide is slower and corn injury can result. DO NOT USE SC 547 Herbicide in the same season as Lorsban®Counter® &RXQWHU® *'\IRQDWH®, and Thimet®. For all corn hybrids, the following table describes the uses of soil applied insecticides prior to an application of SC 547 Herbicide:

Soil Applied Insecticide Use Pattern Use of SC 547 Herbicide in the Same Season Aztec®, PONCHO®927L92®, Regent, Tefluthrin ( e.g. Force®) All No use precautions Chlorpyrifos ( e.g. Lorsban® *  Terbufos ( e.g. Counter® *, Counter® 20CR), Phorate ( e.g. Thimet®), Fonophos ( e.g. Dyfonate®) All Do Not Use

Foliar Insecticide Interaction Information Foliar applications of an organophosphate or carbamate insecticide should not be made within 7 days of an application of SC 547 Herbicide or crop injury may result.

Tank Mixtures for Insect Control To provide weed and insect control in corn, SC 547 Herbicide may be mixed with Baythroid® XL or Oberon® insecticides. Other insecticides that are not organophosphates or carbamates may be effective when mixed with SC 547 Herbicide but have not been evaluated for compatibility in the spray tank or on the crop and should be tested in small quantities and on small areas before large scale use.

WEEDS CONTROLLED BY SC 547 HERBICIDE

PREEMERGENCE BROADLEAF AND GRASS WEED CONTROL

SC 547 Herbicide effectively controls the following grass and broadleaf weeds when applied at 3-6 fl oz/A. In most cases, SC 547 Herbicide alone will not provide season-long residual weed control and should be either tankmixed with additional registered residual preemergence herbicide(s) or be followed by a planned postemergence herbicide application program. POSTEMERGENCE BROADLEAF WEED CONTROL SC 547 Herbicide effectively controls the following broadleaf weeds including biotypes resistant to glyphosate, triazines plant growth regulant, PPO and ALS herbicides when applied at 3 fl oz of product/A along with the recommended adjuvant system. Best control of broadleaf weeds is achieved when weeds are less than 6” in height and actively growing. The addition of atrazine at a minimum of 0.5 lb ai/A will enhance the speed of control, weed spectrum, and consistency of control of many broadleaf weeds, and improve control of weeds larger than 6” in height.

Cultivation Cultivation can help remove partially controlled weeds or multiple flushing weeds. Cultivation can be made at least 7 days before, or after, an application of SC 547 Herbicide.

Late or Rescue Applications Applications of SC 547 Herbicide at 3 fl oz/A may be applied to escaped weeds beyond labeled weed heights. In these situations, partial control and reduced weed competition can be expected. Do not apply SC 547 Herbicide broadcast to field corn, corn grown for silage and white corn more than 20 inches tall or exhibiting seven (7) or more leaf collars, whichever is more restrictive nor to seed corn, sweet corn and popcorn EH\RQGWKH9 stage of growth (5 leaf collars).

15

Yield loss due to competition: Research indicates competition from foxtail (Setaria spp.) exceeding 4 inches in height may reduce corn yields. Delayed applications to foxtail and other weeds that exceed 4 inches in height or the sizes stated on this label increases the risk of yield loss due to prolonged competition with the crop even though control may be acceptable.
