Product Information Armezon® herbicide is a suspension concentrate (SC) herbicide providing systemic postemergence control or growth suppression of emerged broadleaf and grass weeds in field corn (grown for grain, silage, or seed), pop- corn (grown for ear, kernel, or seed), sweet corn (grown for ear, kernel, or seed), sugarcane, between crop applica- tions, and African marigold production. This product may be used on conventional and herbicide-resistant/tolerant corn hybrids. BASF has not tested all inbred lines for toler- ance to Armezon. Before using Armezon, refer to seed company instructions for use on inbred lines of field corn, popcorn, and sweet corn. When applied postemergence as directed, Armezon will control or suppress the broadleaf weeds listed in Table 1 and the grass weeds listed in Table 2. To increase weed control spectrum for use in corn, tank mix Armezon with 0.25 lb to 1.5 lbs active ingredient of atrazine herbicide per acre. Use the lower rates of atrazine for added burndown of emerged weeds and the higher labeled rates for added weed residual control. Armezon applications must include spray additives. See Additives and Mixing Order for details. 5 Table 1.

Armezon controls weeds by inhibiting carotenoid biosynthesis (HPPD- inhibitor Group 27). Temperatures and moisture conditions for active plant growth are important for optimum Armezon activity. Armezon application to weeds during periods of stress conditions, such as cold temperatures and/or drought, may result in reduced performance. Herbicide Resistance Management For resistance management, Armezon contains a Group 27 herbicide. Any weed population may contain plants naturally resistant to Group 27 herbicides. The resistant individuals may dominate the weed population if these herbicides are used repeatedly in the same fields. Appropriate 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 differ- ent target-site-of-action groups as long as the involved products are all registered for the same use, have differ- ent 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 (Integrat- ed 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; and 3. Surviving plants mixed with controlled individuals of the same species. • If resistance is suspected, treat weed escapes with an herbicide with a different MOA and/or use nonchemical methods to remove escapes, as practical, 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. 7 Crop Tolerance Apply Armezon® herbicide during favorable growing conditions for optimum crop tolerance and weed control. Crops under environmental stress are more likely to show injury from any herbicide application. Rarely, plants under these conditions treated with Armezon may show tran- sient bleaching of the portion of the leaves intercepting the spray application. These symptoms are temporary and occur infrequently; crop growth is not affected. Cultivation Avoid disturbing (e.g. cultivation) treated areas for at least 7 days following an application of Armezon to allow best herbicide uptake, translocation, and weed control. Insecticide Information Armezon may be used sequentially or in combination with soil or foliar applied insecticides registered for use in corn. Application Instructions Armezon is effective for post emergence control of annual weeds in conservation or conventional tillage production systems. DO NOT apply Armezon within 30 feet of the downwind edge of native plant communities. The applicator is responsible for any loss or damage that results from spraying Armezon in a manner other than directed in this label. In addition, applicator must follow all applicable state and local regulations and ordinances for spraying. Application Timing • Apply Armezon as a postemergence treatment when weeds are actively growing. • For optimal weed control, apply Armezon before weeds exceed labeled height. • Apply Armezon a minimum of one hour before rainfall or overhead irrigation. Ground Application Methods and Equipment Uniformly apply with properly calibrated ground equipment in 10 or more gallons of water per acre. Use higher water volumes treating larger weeds and/or high-density weed infestation. Weeds must be thoroughly covered with spray. Dense leaf canopies shelter small weeds and can prevent adequate spray coverage. Armezon applications should be made with drop nozzles if the crop canopy prevents adequate weed coverage. Mandatory Spray Drift Management Aerial Applications: • DO NOT release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a great- er 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 S641). • If the wind speed is 10 mph or less, applicators must use 1/2 swath displacement upwind at the downwind edge of the field. When the wind speed is between 11 to 15 mph, applicators must use 3/4 swath displacement. • DO NOT apply when wind speeds exceed 15 mph at the application site. If the wind speed 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. Ground Boom Applications: • User must only apply with the release height recom- mended 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). • DO NOT apply when wind speeds exceed 15 mph at the application site. • DO NOT apply during temperature inversions. 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 - 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 recommend- ed 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. 8 Controlling Droplet Size - Aircraft • Adjust Nozzles - Follow nozzle manufacturer’s recom- mendations 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 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. Additives Postemergence applications of Armezon® herbicide require the addition of an adjuvant and nitrogen fertilizer for optimum weed control. Agriculturally approved drift-reducing additives may be used in applications with Armezon. When an adjuvant is to be used with this product, BASF recommends the use of Chemical Producers and Distribu- tors Association certified adjuvant. Adjuvants Unless specific tank mix directions are given in Crop- specific Information , always use a methylated seed oil (MSO) or a petroleum-based or vegetable seed-based oil concentrate (COC) with Armezon. For best performance across a wide range of environmental conditions, including when weeds are under moisture and/or temperature stress, use an MSO adjuvant. Apply these oilbased adju- vant concentrates at 1.0 to 1.5 gallons per 100 gallons of water (1.0% to 1.5% volume/volume [v/v]). Use the higher rate when applying during periods of hot, dry weather. AND Nitrogen Fertilizer Recommended nitrogen-based fertilizers include urea ammonium nitrate (UAN; 28% to 34%) or ammonium phosphate (10-34-0) at 1.25 to 2.5 gallons per 100 gallons of water (1.25% to 2.5% v/v). Instead of a liquid fertilizer, spray grade ammonium sulfate (AMS) at a minimum rate of 8.5 to 17 pounds per 100 gallons of water may be used. Use the higher rate when applying during periods of hot, dry weather. Mixing Instructions For product containers 5 gallons or less, shake well before use. For product containers more than 5 gallons, recircu- late before use. DO NOT use liquid fertilizer as a carrier for postemergence applications. Use only water as a carrier. 1. Water - Fill the spray tank 1/2 to 3/4 full with clean water and start agitation. 2. Armezon - Add required amount to spray tank while agitating. 3. After the Armezon has visibly dispersed, add spray additives and fill the remainder of the tank with water. Maintain agitation throughout mixing and application until spraying is completed. Limit the amount of spray mixture prepared to that needed for immediate use. Tank Mixing Order When tank mixing Armezon with recommended herbi- cides, add the other herbicides and other components in the following order. Maintain agitation throughout mixing and application until spraying is completed. If the spray mixture is allowed to settle for any period of time, thorough agitation is essential to resuspend the mixture before spraying is resumed. Continue agitation while spraying. 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. Water-soluble additives (including dry and liquid fer- tilizers such as AMS or UAN) 5. Water-dispersible products (such as dry flowables, wettable powders, suspension concentrates, or suspo-emulsions) 6. Water-soluble products 7. Emulsifiable concentrates (including MSO adjuvants) 8. Remaining quantity of water 9 Cleaning Spray Equipment To avoid injury to sensitive crops, drain and clean applica- tion equipment thoroughly using a strong detergent or commercial sprayer cleaner according to the manufactur- er’s directions. Triple rinse equipment before and after applying this product. Tank Mixing Information Armezon® herbicide may be applied sequentially or tank mixed with other herbicides as part of a complete weed control program. Tank mix recommendations are for use only in states where the sequential or tank mix product and application site are registered. Refer to Crop-specific Information for more details and for specific tank mix restrictions. Read and follow the applicable restrictions and precautions and Directions For Use on all products included in any tank mix. The most restrictive labeling applies to tank mixes. Rotational Crop Restrictions The following rotational crops may be planted after apply- ing Armezon at the specified rate. Planting earlier than the specified interval may result in crop injury. Avoid overappli- cation by minimizing overlap of spray swaths and by switching off spray boom when turning (end rows). For rotational crops following the use of sequential applica- tions of Armezon, the rotational interval begins after the last Armezon application.

[**** 12 months for areas with cumulative rainfall <25 inches] Crop-specific Information Corn (field corn, popcorn, seed corn, sweet corn) Apply Armezon postemergence on all corn types includ- ing conventional, Roundup Ready ®, and LibertyLink ® hybrids. In addition, Armezon may be applied on inbred lines used in field corn, popcorn and sweet corn seed pro- duction. Refer to seed company instructions before use on inbred lines. Armezon may be used in tank mixes or sequential appli- cations with other herbicides registered for use in corn. If Armezon is tank mixed with other herbicides, follow label restrictions for the most restrictive tank mix products. It is the pesticide user’s responsibility to ensure that all prod- ucts 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 pre- cautionary statements of each product in the tank mixture. 10 Corn Restrictions • DO NOT apply more than 2.0 fl ozs/A Armezon® herbicide (0.0438 lb topramezone per acre) per year in corn. • In the event of a crop loss because of weather, any corn type can be replanted following an application of Armezon. If Armezon was tank mixed with other herbi- cides, the label restrictions for these herbicides must also be followed. • DO NOT apply Armezon within 45 days of corn harvest (fresh market sweet corn, silage, fodder, or grain) or after the V8 stage of corn growth, whichever comes first. • DO NOT graze or feed treated corn forage, silage, fod- der, or grain for at least 45 days after an application of Armezon. Tank Mixes Armezon may be tank mixed or applied sequentially with one or more of, but not limited to, the following herbicide products: • Outlook ® herbicide [EPA Reg. No. 7969-156; Dimethenamid-P] • Prowl® H2O herbicide [EPA Reg. No. 241-418; Pendimethalin] • Status® herbicide [EPA Reg. No. 7969-242; Diflufenzopyr-sodium and Dicamba, sodium salt] • SurtainTM herbicide [EPA Reg. No. 7969-501; Pyroxasulfone and Saflufenacil] • Zidua® SC herbicide [EPA Reg. No. 7969-374; Pyroxasulfone] • atrazine • glyphosate (e.g. Roundup® herbicide) Armezon tank mixes or sequential applications with prod- ucts containing mesotrione are not recommended. Sequential Herbicide Combinations and Uses In addition to control of many emerged broadleaf weeds, Armezon controls or suppresses growth of several emerged grass weed species. To target a broader spec- trum of grasses, use Armezon as a sequential postemergence treatment following a preemergence grass herbicide such as Outlook, Prowl H2O, Surtain, or Zidua SC. Armezon may also be used in sequential pro- grams with registered burndown herbicides. Armezon may be applied in sequence with products con- taining isoxaflutole (e.g. Corvus ® herbicide) if the isoxaflutole rate used is less than or equal to 0.0625 lb active ingredient per acre (equal to 4 fl ozs/A of Corvus). Between Crop Application (Fallow) Armezon may be used as a foliar application to control emerged broadleaf and grass weeds at any time of the year during the fallow period after crop harvest and before the following crop is planted. For rotational crops following the use of a between crop application of Armezon, the rotational interval begins after the last Armezon applica- tion; see Rotational Crop Restrictions section for intervals. Application Rate and Timing Apply Armezon as a broadcast spray at 0.5 fl oz/A to 2.0 fl ozs/A. Best product performance is obtained when weeds are small and actively growing. Thorough coverage of existing weeds is essential, and higher spray volume may be needed for best performance. Sequential applica- tions may be made with a minimum of 14 days between applications. DO NOT apply more than the maximum cumulative amount of 2.0 fl ozs/A (0.0438 lb topramezone per acre) of Armezon per year. Sugarcane Armezon can be applied to plant cane or sugarcane grown from stubble (ratoon). Armezon may be used in tank mixes or sequential applications with other herbicides registered for use in sugarcane such as atrazine, metribuzin, or Prowl H2O. If Armezon is tank mixed with other herbicides, follow label restrictions for the most restrictive tank mix product. Application of Armezon may cause transient discoloration, chlorosis, or yellowing of sugarcane. Armezon may be applied between growing seasons as either an early preplant in plant cane or post harvest in ratoon cane prior to cane initiating regrowth. Apply 0.5 to 2.0 fl ozs/A of Armezon with a minimum of 14 days between sequential applications. DO NOT apply more than 4.0 fl ozs/A (0.0875 lb topramezone per acre) of Armezon per year. Special Weeds Controlled/Suppressed In addition to the weeds controlled early postemergence as described in Table 1 and Table 2, Armezon controls or suppresses the following weeds. • Common Bermudagrass (Cynodon dactylon) - Apply early in the season at onset of Bermudagrass greenup or emergence of new leaves. Apply 1.0 to 2.0 fl ozs/A of Armezon per application. Up to four sequential applica- tions at 2 to 3 week intervals may be necessary for best control. DO NOT apply more than 4.0 fl ozs/A of Armezon (0.0875 lb topramezone per acre) per year. Apply using MSO or COC spray adjuvant plus nitrogen fertilizer such as AMS or UAN. See Adjuvants and Nitrogen Fertilizer sections for details. • Fall panicum (Panicum dichotomiflorum) - For rescue suppression of large fall panicum more than 12-inches tall or other annual grasses listed in Table 1 and Table 2, apply 2.0 fl ozs/A Armezon and use a mini- mum of 20 gallons per acre spray volume for proper spray coverage. Apply using MSO or COC spray adju- vant plus nitrogen fertilizer such as AMS or UAN. See Adjuvants and Nitrogen Fertilizer sections for details. 11 Sugarcane Restrictions • DO NOT apply more than 2.0 fl ozs/A of Armezon® herbicide (0.0438 lb topramezone/A) per application in sugarcane. • DO NOT apply more than 4.0 fl ozs/A of Armezon (0.0875 lb topramezone/A) per year in sugarcane. • DO NOT exceed a seasonal total of 2.0 fl ozs/A (0.0438 lb topramezone/acre) of Armezon during the final year of sugarcane production, prior to rotation to another crop. • DO NOT apply Armezon within 100 days of sugarcane harvest. • DO NOT graze or feed treated sugarcane for at least 100 days following an application of Armezon. African Marigold Armezon is only registered for use in African marigold grown for the purpose of lutein and zeaxanthin extraction. Use Method, Rate, and Timing Apply Armezon in a single application or sequential appli- cations after complete crop recovery with an interval of 14 days or more. Apply 0.5 to 1.0 fluid ounce of Armezon per acre as a ground broadcast spray. Best product performance is obtained when weeds are small and actively growing. Thorough coverage of existing weeds is essential, and higher spray volume may be needed for best performance. Armezon applications must include spray additives. The specific additive (adjuvant plus nitrogen fertilizer ) requirements for application in African marigold are as follows: • Crop oil concentrate (COC) at 1.5 gallons per 100 gallons of water (1.5% volume/volume), plus • Spray grade ammonium sulfate (AMS) at 8.5 pounds per 100 gallons of water or a liquid nitrogen fertilizer such as urea ammonium nitrate (UAN, 28% to 34%) or ammoni- um phosphate (10-34-0) at 1.25 to 2.5 gallons per 100 gallons of water (1.25% to 2.5% v/v). • DO NOT use methylated seed oil (MSO) as a substitute for COC or severe crop injury may occur. Postemergence. Apply Armezon over-the-top of African marigold when target weeds are actively growing. African marigold plants must have at least 2 to 4 full leaves with a minimum height of 3 to 5 inches, before an Armezon application can be made. Postemergence-directed. Apply Armezon as a postemergence- directed spray beneath the canopy of established plants and between rows for postemergence weed control. African Marigold Restrictions • DO NOT apply more than 1.0 fl oz/A of Armezon (0.022 lb topramezone/A) per application in African marigold. • DO NOT apply more than 2.0 fl ozs/A Armezon (0.0438 lb topramezone per acre) per year in African marigold. • DO NOT graze livestock in treated fields or feed treated plant materials to animals. • DO NOT apply by air. • Avoid overlapping spray patterns because crop injury can occur. 12 © 2024 BASF Corporation All rights reserved. 007969-00262.20240430c.NVA 2024-04-0216-0081 Supersedes: NVA 2022-04-0216-0159 Supplemental: NVA 2017-04-216-0214 BASF Corporation 26 Davis Drive Research Triangle Park, NC 27709 Armezon, Outlook, Prowl, Status, and Zidua are registered trademarks of BASF.
