IMPORTANT CROP SAFETY INFORMATION READ BEFORE USING THIS PRODUCT Postemergence applications of 216-18 HERBICIDE may be made only to corn resistant to the active ingredients in this product. To the extent consistent with applicable law, AMVAC does not warrant the use of this product on corn other than those designated as LibertyLink to safely withstand the application of 216-18 HERBICIDE. The basis of selectivity of 216-18 HERBICIDE in corn is the presence of a gene in LibertyLink corn which results in resistant corn plants to glufosinate, one of active ingredients in 216-18 HERBICIDE. Crops not containing this gene will not be resistant to 216-18 HERBICIDE and severe crop injury and/or death may occur. DO NOT allow spray to contact foliage or green tissue of desirable vegetation other than crops resistant to the active ingredients in this product.

637-20210210 20210211 216-18 HERBICIDE Label Amendment Page 4 of 14 I. PRODUCT INFORMATION 216-18 HERBICIDE contains both a systemic postemergence herbicide (topramazone) and a water-soluble nonselective, contact herbicide (glufosinate) for selective control or growth suppression of emerged broadleaf and grass weeds in LibertyLink (LL) field corn (grown for grain or silage) and LL sweet corn. This product may only be used on LibertyLink resistant field corn and sweet corn hybrids. 216-18 HERBICIDE is absorbed by plant foliage and controls weeds by inhibiting glutamine biosynthesis (Group 10) and carotenoid biosynthesis (Group 27). 216-18 HERBICIDE is foliar active with limited residual soil activity. Weeds that emerge after application may not be controlled. Apply to small, actively growing weeds before weeds exceed the maximum stem height or vine length listed for broadleaf weeds listed in Table 1 and grass weeds listed in Table 2.

216-18 HERBICIDE requires uniform thorough spray coverage. Applications made in warm temperatures, high humidity, bright sunlight, and made between dawn and 2 hours before sunset will improve activity. Weed control may be reduced if application is made when heavy dew and mist/rain are present; or when weeds are under stress due to environmental conditions including drought, cool temperatures, or extended periods of cloudiness. Necrosis of leaves and young shoots may occur within 2 to 4 days after application under good growing conditions. Total herbicidal symptomology on weeds may take up to 14 days after application.

216-18 HERBICIDE is rainfast four (4) hours after application to most weed species; therefore, rainfall within four (4) hours may necessitate retreatment or may result in reduced weed control.

216-18 HERBICIDE may be tank-mixed with other registered herbicides used to provide both a broader spectrum of weed control and residual weed control. Atrazine at 0.25 to 0.5 lb active ingredient per acre significantly increases the weed activity of 216-18 HERBICIDE. Refer to Tank Mixes in the Crop Use Directions (Section VII). It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and the precautionary statements of each product in the tank mixture.

216-18 HERBICIDE applications must also include specified spray additives. Refer to Additives and Mixing Order (Sections III and IV).

Weed Resistance Management Herbicide resistance has become an important management focus to maximize weed control. Weeds have developed resistance to many herbicide modes of action. 216-18 Herbicide contains both a Group 10 (glufosinate-ammonium) and a Group 27 (topramezone) herbicide to reduce development of herbicide resistance in weeds. Any weed population may contain plants resistant to Group 10 and/or Group 27 herbicides. Resistant plants may dominate weed populations if Group 10 and Group 27 herbicides are used repeatedly in the same fields. It is recommended to follow effective resistance-management strategies.

Follow as many as possible of the following recommendations to delay herbicide resistance in weeds: Rotate the use of 216-18 Herbicide or other Group 10 and 27 herbicides in the same and successive growing seasons with herbicides of different groups that control the same weeds. Use tank mixtures with labeled herbicides containing active ingredients that are effective on both susceptible and resistant weed species. Use the highest label rates allowed to achieve the highest weed control. Weed resistance does not develop when weeds do not survive the herbicide treatment. Consult your local extension service or certified crop advisor if unsure of weed susceptibility to each herbicide active ingredient.

637-20210210 20210211 216-18 HERBICIDE Label Amendment Page 7 of 14 Adopt an integrated weed-management program that includes non-herbicide components, such as, scouting, use of historical information related to herbicide use and crop rotation; mechanical control practices including various forms of tillage and hand removal; cover crops; cultural control practices including crop rotation, row spacing, and using higher crop seeding rates, weed- competitive crops or varieties, and precision fertilizer application and timing to favor the crop and not weeds); biological control agents, if available; and other management practices. Scout before and after herbicide applications to monitor development of herbicide resistance in weed populations. 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 herbicide resistance in weeds is suspected, prevent weed seed production in the affected area by hoeing or hand removal, using an effective herbicide from a different group, or by a mechanical method such as 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 population continues to progress after treatment with this product, discontinue use of this product and use other management strategies. Only use herbicides with a different mode of action, if available. Contact your local extension specialist or certified crop advisors for additional herbicide resistance-management and integrated weed-management recommendations for specific crops and weed species. For further information or to report suspected resistance, contact AMVAC Chemical Corporation at 1-888-462-6822.

Best Management and Stewardship Practices Adopt a diversified weed management system for best stewardship of 216-18 HERBICIDE and for optimum weed control. Best management practices that diversify weed management include using herbicide treatments with multiple modes of action (MOA) that are effective on target weeds. Apply herbicides correctly and in proper application, including timing, full use-rates and appropriate spray volumes. Use highest rates of effective herbicides when combined and in herbicide and crop rotation. Use cultural (e.g., crop rotation) and mechanical (e.g., tillage) weed management tactics. Alternate herbicide-resistant traits and/or use herbicide-resistant trait stacks for more efficient rotation. Correctly identify weeds and know where the weeds are in your fields. Start with clean fields. Effective tillage or the use of a burndown herbicide program can control emerged weeds prior to planting. Clean equipment to prevent the spread of weeds seeds. Use residual herbicides in pre-emergence and early post-emergence applied applications. Scout fields soon after herbicide application to identify escaped weeds, population shifts, and herbicide resistant biotypes. Closely monitor problematic areas with difficult-to-control weeds or dense weed populations. Control weed escapes by spot herbicide applications, rope wicking, cultivation or hand removal of weeds or other techniques to stop weed seed production and accumulation in the soil bank. Stopping weed seed development will decrease weed populations from year to year and prevent major weed shifts.

Crop Resistance Apply 216-18 HERBICIDE during favorable growing conditions for optimum crop resistance and weed control. Crops under environmental stress are more likely to show injury from any herbicide application. Rarely, plants under environmental stress conditions and treated with 216-18 HERBICIDE may show some transient discoloration of the portion of the leaves intercepting the spray application. These symptoms are temporary and occur rarely, and crop growth is not affected.

Cultivation Avoid disturbing (e.g., cultivation) treated areas for at least 5 days before and 7 days following an application of 216-18 HERBICIDE to allow maximum herbicide absorption and weed control. Avoid deep cultivation that will move dormant weed seeds into the upper soil zone where seeds may germinate.

Insecticide Information 216-18 HERBICIDE may be used sequentially or in combination with soil or foliar applied insecticides registered for use in LibertyLink corn.

Cleaning Spray Equipment To avoid injury to sensitive crops, drain and clean application equipment thoroughly using a strong detergent or commercial sprayer cleaner according to the manufacturer’s directions. Clean and triple rinse equipment before and after applying this product.

II. APPLICATION AND MIXING INSTRUCTIONS 216-18 HERBICIDE applied postemergence controls many annual weeds in conservation and conventional tillage crop production systems. DO NOT apply 216-18 HERBICIDE within 30 feet of a native plant community. To the extent consistent with applicable law, the applicator is responsible for any loss or damage that results from spraying 216-18 HERBICIDE in a manner other than specified in this label. In addition, applicator must follow all applicable state and local regulations and ordinances in regards to spraying.

637-20210210 20210211 216-18 HERBICIDE Label Amendment Page 8 of 14 Spray Coverage Weed plant must be thoroughly covered with spray droplets to achieve optimum and consistent control of emerged weeds. Dense leaf canopies can prevent adequate spray coverage resulting in poor weed control. DO NOTuse flood jet nozzles, controlled droplet application equipment, or air-assisted spray equipment. Ground Application Methods and Equipment Apply 216-18 HERBICIDE with properly calibrated ground equipment in a minimum of 15 or more gallons of water per acre. Use higher water volumes when treating larger weeds and/or dense weed infestations. 216-18 HERBICIDE applications can be made with drop nozzles if the crop canopy prevents adequate weed coverage using broadcast applications methods. Apply at ground speed of less than 15 mph to attain adequate coverage.

After using 216-18 HERBICIDE, triple rinse the spray equipment and clean with a commercial tank cleaner before using the equipment for a new application. Make sure any rinsate or foam is thoroughly removed from spray tank and boom.

Mandatory Spray Drift Mitigation:When applying to crops via aerial application equipment, the spray boom must be mounted on the aircraft so as to minimize drift caused by wing tip or rotor blade vortices. The boom length must not exceed 75% of the wingspan or 90% of the rotor blade diameter. When applying to crops via aerial application equipment, applicators must use 1/2 swath displacement upwind at the downwind edge of the field. DO NOT apply when wind speeds exceed 10 miles per hour at the application site. DO NOT apply during temperature inversions. For aerial applications, DO NOT release spray at a height greater than 10 feet above the crop canopy, unless a greater application height is required for pilot safety. For ground applications and aerial applications, select nozzle and pressure that deliver medium to coarse spray droplets as indicated in nozzle manufacturer’s catalogues and in accordance with ASABE Standard 572.1. Spray at the appropriate boom height based on nozzle selection and nozzle spacing, but do not exceed a boom height of 24 inches above target pest or crop canopy. Set boom to lowest effective height over the target pest or crop canopy based on equipment manufacturer’s directions. Automated boom height controllers are recommended with large booms to better maintain optimum nozzle to canopy height. Excessive boom height will increase the potential for spray drift.

Advisory Spray Drift Language Pollinator Advisory: This product contains an herbicide. Follow all label directions and precautions to minimize potential off- target exposure in order to prevent effects to non-target plants adjacent to the treated site which may serve as habitat or forage for pollinators. Spray Drift Management: The interaction of many equipment and weather-related factors determines the potential for spray drift. The applicator is responsible for considering all these factors when making application decisions. Importance of Droplet Size: The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the largest droplets that provide sufficient coverage and control. The presence of sensitive species nearby, the environmental conditions, and pest pressure may affect how an applicator balances drift control and coverage. APPLYING LARGER DROPLETS REDUCES DRIFT POTENTIAL, BUT WILL NOT PREVENT DRIFT IF APPLICATIONS ARE MADE IMPROPERLY OR UNDER UNFAVORABLE ENVIRONMENTAL CONDITIONS! See Wind, Temperature and Humidity, and Temperature Inversions sections of this label.

Techniques for Controlling Droplet Size: Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce larger droplets. Pressure - Use the lower spray pressures recommended for the nozzle. Higher pressure reduces droplet size and does not improve canopy penetration. WHEN HIGHER FLOW RATES ARE NEEDED, USE A HIGHER CAPACITY NOZZLE INSTEAD OF INCREASING PRESSURE. Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray angles produce larger droplets. Consider using low-drift nozzles.

637-20210210 20210211 216-18 HERBICIDE Label Amendment Page 9 of 14 Controlling Droplet Size – Aircraft: Number of Nozzles - Use the minimum number of nozzles with the highest flow rate that provide uniform coverage. Nozzle Orientation - Orienting nozzles so that the spray is emitted backwards, parallel to the airstream will produce larger droplets than other orientations. AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR. Nozzle Type - Solid stream nozzles (such as disc and core with swirl plate removed) oriented straight back produce larger droplets than other nozzle types. Boom Length - Longer booms increase drift potential. Therefore, a shorter boom length is recommended. Application Height - Application more than 10 ft above the canopy increases the potential for spray drift.

Boom Height. Setting the boom at the lowest referenced height (if specified) which provides uniform coverage reduces the exposure of droplets to evaporation and wind. For ground equipment, the boom should remain level with the crop and have minimal bounce.

Drift Reduction Technology (DRT). The EPA Drift Reduction Technology (DRT) Program was developed to encourage the manufacture, marketing, and use of spray technologies scientifically verified to significantly reduce pesticide drift. The use of DRTs should result in significantly less pesticide from spray applications drifting and being deposited in areas not targeted by those applications, compared to spray technologies that do not meet the minimum DRT standard. EPA-verified drift reduction technologies (DRTs) and their ratings will be added to the following webpage as they become available: https://www.epa.gov/reducing-pesticide-drift/epa-verifiedand-rated-drift- reduction-technologies.

Wind.Drift potential increases at wind speeds of less than 3 mph (due to inversion potential) or more than 10 mph. However, many factors, including droplet size and equipment type determine drift potential at any given wind speed. AVOID APPLICATIONS DURING GUSTY OR WINDLESS CONDITIONS. Note: Local terrain can influence wind patterns. Every applicator needs to be familiar with local wind patterns and how they affect spray drift.

Temperature and Humidity.When making applications in hot and dry conditions, set up equipment to produce larger droplets to reduce effects of evaporation.

Temperature Inversions. Drift potential is high during a temperature inversion. Temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain close to the ground and move laterally in a concentrated cloud. Temperature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. They begin to form as the sun sets and often continue into the morning. Their presence can be indicated by ground fog; however, if fog is not present, inversions can also be identified 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.

Shielded Sprayers. Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the responsibility of the applicator to verify that the shields are preventing drift and not interfering with uniform deposition of the product.

Agriculturally approved drift-reducing additives may also be used in accordance with product labels.

III. ADDITIVES Postemergence applications of 216-18 HERBICIDE require the addition of an adjuvant and a nitrogen fertilizer source to achieve optimum weed control.

1. ADJUVANTS: Preferred adjuvants include: MSO (methylated seed oil) adjuvants at 1% v/v (1 gallon/100 gallons of water) or HSMOC (high surfactant methylated oil concentrate) adjuvants at 0.5 to 0.75% v/v (2 to 3 qts/100 gallons of water). MSO or HSMOC adjuvants will result in greater weed control across a wide range of environmental conditions including when weeds are under moisture and/or temperature stress. Petroleum oil concentrate (COC) adjuvants may also be used 1% v/v. For adjuvant use when tank-mixing with other herbicides refer to Section VII. Crop Use Directions – Tank Mixes.

Prior to adding 216-18 HERBICIDE to the spray tank, ensure that the spray tank is thoroughly clean, particularly if an herbicide with the potential to injure crops other than corn was previously used. 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.

Following are mixing order guidelines for 216-18 HERBICIDE either alone or with other components, including spray adjuvants: WATER:

1. Fill the spray tank ½ to ¾ full with clean water.
2. Add the required amount of 216-18 HERBICIDE to the spray tank while agitating.
3. After 216-18 HERBICIDE has visibly dispersed, continue agitation and add spray additives while filling the remainder of the tank with water.

TANK-MIX PREPARATION: When tank-mixing 216-18 HERBICIDE with specified herbicides, add the other herbicides and other components in the following order, all while agitating:

1. Fill spray tank ½ to ¾ full with clean water and start agitation.
2. Add soluble packet products and thoroughly mix.
3. Add 216-18 HERBICIDE and thoroughly mix.
4. Add WP (wettable powder), DG (dispersible granule), DF (dry flowable), or F (liquid flowable) formulations.
5. Add EC (emulsifiable concentrate) and liquid products.
6. Add fertilizer and spray adjuvants to the spray tank.
7. Use a silicone based anti-foam agent if foaming occurs.
8. Fill the remainder of the tank with water.
9. Maintain adequate agitation until all contents in the tank are applied.

V. TANK MIX INFORMATION 216-18 HERBICIDE may be used sequentially or tank mixed with other herbicides as part of a complete weed control program. Tank mix directions are for use only in states where the sequential or tank mix product and application site is registered. Refer to Crop Use Directions (Section VII) for more details and for specific tank mix restrictions. Read and follow the applicable Restrictions and Limitations (Section VI) and Directions for Use on all products included in any tank mix. The most restrictive labeling applies to tank mixes.
