PRODUCT INFORMATION

Scepter 70 DG herbicide is a flexible broad-spectrum herbicide which may be applied postharvest of prior season crop but before winter freeze-up provided next crop is soybeans, preplant incorporated, preemergence or postemergence in soybeans., preplant incorporated, preemergence or postemergence in soybeans. When Scepter 70 DG herbicide is applied to the soil, susceptible weeds may emerge but, growth stops, and the weeds either die or are not competitive with the crop. When Scepter 70 DG herbicide is applied postemergence, absorption occurs through both the foliage and roots. Susceptible weeds stop growing and either die or are not competitive with the crop. A timely cultivation may aid in the control of certain weeds or improve weed control when adequate moisture is not received after application. Cultivation should be shallow. After postemergence treatments, wait at least 10 days before cultivating. Scepter 70 DG herbicide is absorbed by weed roots and/or foliage and is rapidly translocated to growing points. Therefore, adequate soil moisture is necessary for optimum Scepter 70 DG herbicide activity. The amount of rainfall or irrigation required following application depends on existing soil moisture, soil texture and organic matter content. Sufficient water to moisten the soil to a depth of 2 inches is normally adequate. If adequate moisture is not received within 7 days after treatment, then a cultivation or postemergence herbicide application can improve weed control. When adequate moisture is received after dry conditions, Scepter 70 DG herbicide will provide residual control of susceptible germinating weeds; activity on established weeds will depend on the weed species and weed size. Occasionally, internode shortening of soybean plants may occur from Scepter 70 DG herbicide applications. The internode shortening does not impact soybean yields. Some of the weeds listed on this label have populations with evolved resistance to HG 2 (ALS/AHAS inhibiting) herbicides. If HGHG 2 resistant biotypes are present in a field, tank-mix or apply Scepter 70 DG herbicide sequentially with an alternate registered herbicide having an effective mode of action to ensure control. Consider including cultural and mechanical tactics to supplement herbicides when herbicide-resistant weed biotypes are present in fields. See your AMVAC representative for additional information. WEED RESISTANCE MANAGEMENT For resistance management, Scepter 70 DG herbicide is a Group 2 herbicide. Any weed population may contain or Formatted: Right: 0.26"

610-20220117 DFU amend_REDLINE Page 4 of 18 develop plants naturally resistant to Scepter 70 DG herbicide and other Group 2 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate resistance management strategies should be followed. To delay herbicide resistance take one or more of the following steps: • Rotate the use of Scepter 70 DG herbicide or other Group 2 herbicides within a growing season sequence or among growing 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 AMVAC Chemical at 1-888-462-6822.

PRECAUTIONS Crops other than soybeans, such as cotton, corn and vegetables, may be injured by spray drift or other contact with Scepter 70 DG herbicide. To avoid injury to sensitive crops from spray drift, follow all use directions and precautions in SPRAYING INSTRUCTIONS section.

To avoid injury to sensitive crops, spray equipment used for Scepter 70 DG herbicide applications must be drained and thoroughly cleaned with water before being used to apply other products to these crops. Use of Scepter 70 DG herbicide in accordance with label directions is expected to result in normal growth of rotational crops in most situations; however, various environmental and agronomic factors make it impossible to eliminate all risks associated with the use of this product and, therefore, rotational crop injury is possible. See ROTATIONAL CROP RESTRICTIONS section. Replanting: If replanting is necessary in a field previously treated with Scepter 70 DG herbicide, the field may be replanted to soybeans at any time. Rework the soil no deeper than the treated zone. DO NOT apply a second treatment of Scepter 70 DG herbicide.

RESTRICTIONS DO NOT use Scepter 70 DG herbicide other than in accordance with the instructions set forth on this label or approved supplemental labels. DO NOT apply this product more than once per year to soybeans. DO NOT apply more than 2.8 ounces of Scepter 70 DG herbicide per acre per year. There must be an interval of at least 90 days between Scepter 70 DG herbicide application and soybean harvest.

610-20220117 DFU amend_REDLINE Page 5 of 18 DO NOT graze or feed treated soybean forage, hay or straw to livestock.

AERIAL APPLICATIONS: Uniformly apply with properly calibrated aerial equipment in 5 or more gallons of water per acre. To avoid injury to sensitive crops from drift, aerial applicators must adhere to the following SPECIAL AERIAL USE DIRECTIONS AND PRECAUTIONS: Nozzles must be pointed toward the rear of the aircraft. The downward angle of the nozzle should not be greater than 20 degrees. Use a maximum spray pressure of 40 psi. A buffer zone must be established between the area to be sprayed and sensitive crops. To the extent consistent with applicable law applicator is responsible for any loss or damage which results from spraying Scepter 70 DG herbicide in a manner other than directed in this label. In addition, applicator must follow all applicable state and local regulations and ordinances in regard to spraying.

DIRECTIONS FOR CONVENTIONAL, MINIMUM, AND NO-TILL APPLICATIONS APPLICATION RATE Apply Scepter 70 DG herbicide at a maximum broadcast rate of 2.8 ounces per acre for preplant incorporated and preemergence (including minimum and no-till systems) applications. Apply Scepter 70 DG herbicide at a broadcast rate of 1.4 to 2.8 ounces per acre for postemergence applications. NOTE: In USE REGION 3 as defined by the USE AREA section of this label, apply Scepter 70 DG herbicide prior to July 1.

APPLICATION INSTRUCTIONS SOIL APPLICATIONS Scepter 70 DG herbicide may be applied following fall crop harvest and prior to winter freeze-up. Fall applications will provide residual control of winter annual and early spring germinating weed species. Apply Scepter 70 DG herbicide at 2.8 ounces per acre in tank mixture with other herbicides registered for fall application before soybean, such as 2,4-D, glyphosate or metribuzin for control of emerged weeds or additional residual weed control spectrum. Include adjuvants recommended by tank-mix partner for emerged weed control.

Soybean must be planted the spring following fall application of Scepter 70 DG herbicide. For control of in-crop emerging weeds, other registered soybean herbicides may be applied. Do not make more than one application of Scepter 70 DG per soybean crop year. For determining rotational crop plant-back interval, base the interval on soybean planting date rather than date of herbicide application.

Scepter 70 DG herbicide may be applied in conventional, minimum, or no-till as a preplant incorporated or preemergence application up to 45 days (30 days in USE REGION 1) before planting. Preplant incorporated applications may be applied immediately before planting or up to 30 days prior to planting in USE REGION 1. For USE REGION 2 and USE REGION 3, Scepter 70 DG herbicide may be applied up to 45 days prior to planting. Incorporate uniformly into the top 1 to 2 inches of soil within 7 days after application. If soybeans are planted on beds, apply and incorporate after bed formation using PTO-driven equipment or rolling cultivator. Preemergence applications may also be applied during or after planting but before the crop emerges. Adequate moisture is required for activation of Scepter 70 DG herbicide.

Tank mixes: Scepter 70 DG herbicide may be applied preplant incorporated or preemergence in a tank-mixture with the following products registered for preplant or preemergence use to improved residual weed control spectrum in soybeans and to better manage herbicide- resistant weed populations. Products listed for tank-mixture with Scepter 70 DG herbicide must be registered for preplant incorporated or preemergence application in soybean. Read and follow the label directions of all products in the tank-mixture. Tank-mixtures with Scepter 70 DG herbicide are not limited to the tank-mix partners listed below. It is the pesticide user’s responsibility to ensure that all products are registered for the intended use.

Glyphosate, paraquat or glufosinate may be mixed with Scepter 70 DG herbicide when applied before soybean emergence.

POSTEMERGENCE APPLICATIONS Scepter 70 DG herbicide applied postemergence controls the emerged weed species listed previously, but can also provide residual control of susceptible weeds that may emerge after application. Weeds should be small and actively growing. Weeds stressed by temperature and moisture extremes may not be effectively controlled. To maximize weed control following a postemergence Scepter 70 DG herbicide application, wait at least 10 days before cultivating. This timely cultivation will enhance residual weed control, especially under dry conditions. There must be an interval of at least 90 days between the Scepter 70 DG herbicide application and soybean harvest. Apply Scepter 70 DG herbicide at least 1 hour prior to rainfall or irrigation.

Tank mixes: Scepter 70 DG herbicide may be applied postemergence in a tank-mixture with the following products registered for postemergence use, in conventional or herbicide tolerant soybean systems, to improve weed control spectrum in soybeans and to better manage herbicide-resistant weed populations. Products listed for tank-mixture with Scepter 70 DG herbicide must be registered for postemergence application in soybean. Tank-mixtures with Scepter 70 DG herbicide are not limited to the tank-mix partners listed below. 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: Assure II® (quizalofop-P-ethyl), Fusilade® DX (fluazifop-P-butyl), Fusion (fluazifop-P-butyl + fenoxaprop-P-ethyl), Hoelon (diclofop), Poast®/Poast Plus® (sethoxydim), Select®/Select Max®/Section®/Arrow® (clethodim), Blazer/Ultra Blazer® (acifluorfen), Cobra®/Phoenix® (lactofen), Reflex®/Flexstar®/Rumble/Dawn/Rhythm (fomesafen) Roundup brands (glyphosate) or Liberty (glufosinate). Glyphosate or glufosinate may be mixed with Scepter 70 DG herbicide when applied to genetically modified soybean cultivars where glyphosate or glufosinate is labeled for use. In some cases, the activity of group 1 postemergence grass herbicide (e.g. Assure II, Fusilade DX and Select) may be reduced when mixed with Scepter 70 DG herbicide. The reduction in activity may be overcome by delaying the application of the postemergence grass herbicide 7 days following the application of Scepter 70 DG herbicide. If the grass herbicide is applied first, wait 3 days before applying Scepter 70 DG herbicide. Refer to the respective grass herbicide label for recommended application rate, weed size and restrictions.

Use a nonionic surfactant at 1-2 qt./100 gallons of water (0.25-0.50% v/v) or oil-based adjuvant such as methylated seed oil (MSO) at 0.5 to 1.5 qt1 gallon./100 gallons of water (0.5-1% v/v) or crop oil concentrate (COC) at 1 to 2 gallonsqt./100 gallons of water (1-2% v/v) containing at least 14% emulsifiers and 80% oil active ingredient. Refer to the specific surfactant label for more specific use instructions. Apply the adjuvant at rate stated on manufacturer use label. When Scepter 70 DG herbicide is applied postemergence in a mixture with other herbicides, refer to the companion herbicide label for adjuvant recommendations. A nitrogen fertilizer source can be added including urea ammonium nitrate (UAN; 28-3432%) or ammonium phosphate (10-34-0) at 1.25 to 2.5 gallons per hundred gallons of water (1.25% to 2.5% v/v). Instead of a liquid fertilizer, spray grade ammonium sulfate (AMS) at 8.5 to 17 pounds per 100 gallons of water (or an equivalent liquid AMS product) may be used. Use the higher rate when making application during periods of hot dry weather and to larger weeds.

MIXING INSTRUCTIONS Fill the spray tank one-fourth to one-half full with clean water. While agitating add the required amount of Scepter 70 DG herbicide, and then fill the remainder of the tank with water. For postemergence applications, add the NIS, MSO, or COC as last ingredient in the tank. An antifoaming agent may be added to the tank if needed. Maintain agitation while spraying to ensure a uniform spray mixture.

When tank mixing Scepter 70 DG herbicide with directed herbicides, add Scepter 70 DG herbicide to the spray tank first and make sure it is thoroughly mixed before adding the other herbicide. Mixing instructions on the tank mix component herbicides need to be followed.

SOIL APPLICATIONS IN LIQUID FERTILIZERS Scepter 70 DG herbicide can be applied to the soil in liquid fertilizers. If Scepter 70 DG herbicide is applied in liquid fertilizer as a carrier, a pre-slurry must first be made. Scepter 70 DG herbicide must be completely dispersed in at least one gallon of water. Always test the compatibility of the Scepter 70 DG herbicide slurry with the liquid fertilizer before mixing in the spray tank. Follow all Scepter 70 DG herbicide label directions regarding incorporation, timing of application, special instructions and precautions. Apply treatments in 20 or more gallons of liquid fertilizer per acre with ground equipment. All individual state regulations relating to fluid fertilizer mixing, registration, labeling and application are the responsibility of the individual and/or company selling the Scepter 70 DG herbicide/liquid fertilizer mixture.

SPRAYING INSTRUCTIONS NOTE: DO NOT apply if wind conditions, temperature inversion conditions, or other conditions may cause drift onto adjacent areas or sensitive crops. Sensitive crops include but are not limited to leafy vegetables, sugarbeets, and cotton.

Avoid overlaps when spraying.

GROUND APPLICATIONS: Uniformly apply with properly calibrated ground equipment in 10 or more gallons of water per acre. Use sprayers equipped with nozzles that provide accurate and uniform application. To minimize drift, use a maximum spray pressure of 40 psi. To ensure thorough coverage, use a minimum of 20 gallons of water per acre when applying Scepter 70 DG herbicide as a postemergence treatment. Use higher gallonage for fields with dense vegetation or heavy crop residues.

For band treatment, apply the broadcast equivalent rate and volume per acre. To determine these:

Broadcast Band Band width in inches Row width in inches x RATE per acre = RATE per acre

Broadcast Band Band width in inches Row width in inches x VOLUME per acre = VOLUME per acre

610-20220117 DFU amend_REDLINE Page 13 of 18 SPRAY DRIFT MANAGEMENT SPRAY DRIFT Ground Boom Applications: User must only apply with the release height recommended by the manufacturer, but no more than 3 feet above the ground or crop canopy unless making a turf, pasture, or rangeland application, in which case applicators may apply with a nozzle height no more than 4 feet above the ground. For applications prior to the emergence of crops and target weeds, applicators are required to use a coarse or coarser droplet size (ASABE S572.1). For all other applications, applicators are required to use a medium or coarser droplet size (ASABE S572.1). Do not apply when wind speeds exceed 15 miles per hour at the application site. Do not apply during temperature inversions. Boomless Ground Applications: Applicators are required to use a medium or coarser droplet size (ASABE S572.1) for all applications. Do not apply when wind speeds exceed 15 miles per hour at the application site. Do not apply during temperature inversions. SPRAY DRIFT Aerial Applications: Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a greater application height is necessary for pilot safety. For applications prior to the emergence of crops and target weeds, applicators are required to use a Ccoarse or coarser droplet size (ASABE S572.1). For all other applications, applicators are required to use a Mmedium or coarser droplet size (ASABE S572.1). Applicators must use ½ swath displacement upwind at the downwind edge of the field. Do not apply when wind speeds exceed 15 mph at the application site. If the windspeed is greater than 10 mph, the boom length must be 65% or less of the wingspan for fixed wing aircraft and 75% or less of the rotor diameter for helicopters. Otherwise, the boom length must be 75% or less of the wingspan for fixed-wing aircraft and 90% or less of the rotor diameter for helicopters Do not apply during temperature inversions.

SPRAY DRIFT Spray Drift Advisories: THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL 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 - 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. Controlling Droplet Size – Aircraft Adjust Nozzles - Follow nozzle manufacturers’ recommendations for setting up nozzles. Generally, to reduce fine droplets, nozzles should be oriented parallel with the airflow in flight. BOOM HEIGHT – Ground Boom For ground equipment, the boom should remain level with the crop and have minimal bounce. RELEASE HEIGHT - Aircraft Higher release heights increase the potential for spray drift.

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 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.

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.

SPRAY DRIFT ADVISORIES Boom-less Ground Applications: • Setting nozzles at the lowest effective height will help to reduce the potential for spray drift. Handheld Technology Applications: • Take precautions to minimize spray drift. WEED RESISTANCE MANAGEMENT For resistance management, Scepter 70 DG herbicide is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to Scepter 70 DG herbicide and other Group 2 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate resistance management strategies should be followed. To delay herbicide resistance take one or more of the following steps: • Rotate the use of Scepter 70 DG herbicide or other Group 2 herbicides within a growing season sequence or among growing 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 AMVAC Chemical at 1-888-462-6822.
