2.6 Environmental Hazards Do not apply directly to water, to areas where surface water is present, or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment wash water or rinsate. 2.6.1 Groundwater Advisory

A22670 contains the active ingredients bicyclopyrone and S-metolachlor which are known to leach through soil into groundwater under certain conditions as a result of label use. This chemical may leach into groundwater if used in areas where soils are permeable, particularly where the water table is shallow.

6 2.6.2 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 a high potential for reaching surface water via runoff for several weeks or months 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 bicyclopyrone, mesotrione and S-metolachlor 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. 2.6.3 Mixing/Loading/Applications Restrictions This product may not be mixed or loaded within 50 ft. of perennial or intermittent streams and rivers, natural or impounded lakes and reservoirs. This product may not be mixed/loaded or used within 50 ft. of all wells, including abandoned wells, drainage wells, and sink holes. Operations that involve mixing, loading, rinsing, or washing of this product into or from pesticide handling or application equipment or containers within 50 ft. of any well are prohibited unless conducted on an impervious pad constructed to withstand the weight of the heaviest load that may be positioned on or moved across the pad. Such a pad shall be designed and maintained to contain any product spills or equipment leaks, container or equipment rinse or wash-water, and rainwater that may fall on the pad. Surface water shall not be allowed to either flow over or from the pad, which means the pad must be self- contained. The pad shall be sloped to facilitate material removal. An unroofed pad shall be of sufficient capacity to contain at a minimum 110% of the capacity of the largest pesticide container or application equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclude precipitation from contact with the pad shall have a minimum containment capacity of 100% of the capacity of the largest pesticide container or application equipment on the pad. Containment capacities as described above shall be maintained at all times. The above-specified minimum containment capacities do not apply to vehicles when delivering pesticide shipments to the mixing/loading site.

2.6.4 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. 2.6.5 Reporting Ecological Incidents

3.0 PRODUCT INFORMATION A22670 may be used preemergence and postemergence in the culture of field corn and seed corn. A22670 may also be used in the culture of sweet corn and yellow popcorn but the application must be made prior to crop emergence, (i.e., preplant or preemergence) or severe crop injury may occur. A22670 may be used in all tillage systems including reduced and no-till systems. The highest levels of in-crop residual weed control will be obtained when applications are made as close to planting as possible. Applied according to use directions and under normal growing conditions, A22670 will not harm the treated crop. During germination and early stages of growth, environmental conditions or other factors that favor poor or slow growth can weaken crop seedlings. A22670 used under these conditions can result in crop injury. A22670 is a combination of the herbicides bicyclopyrone, mesotrione and s-metolachlor plus the safener benoxacor. Determine the soil type and organic matter of the soil on which the application is to be made prior to application. The use rate of A22670 is based on soil type and percent soil organic matter. A22670 is recommended for management of the weed species listed in Section 8.0.

3.1 Weed Resistance Management

A22670 is a combination of bicyclopyrone, mesotrione and S-metolachlor herbicides. Naturally occurring biotypes of certain weed species with resistance to triazines, ALS, PPO, Glycine (glyphosate) and HPPD-inhibiting herbicides are known to exist. If biotypes of weeds resistant to triazines, ALS, PPO and glycine inhibitors are present in the field, this herbicide should control them if they are listed in Section 8.0. To reduce the risk of weeds developing resistance to HPPD-inhibiting herbicides, implement a program including both preemergence and/or postemergence herbicides that provides effective control of all weeds using multiple modes of action. This includes scouting fields before application to ensure the herbicide will be appropriate for the weeds present. Scout fields and eliminate weed escapes. If suspected weed resistance is observed against a particular weed species, contact your Syngenta or retailer representative or call Syngenta Customer Service (1-800-334-9481). Lack of weed control is not necessarily an indicator of weed resistance.

9 Consider weed resistance management strategies that include two or more modes of action where a minimum of two modes of action are effective at controlling the target weed when either are applied alone. Read and follow all label directions.

A22670 contains three herbicide active ingredients and two modes of action and can be an effective component of a weed resistance management strategy.

3.1.1 Principles of Herbicide Resistant Weed Management Scout and know your field • Know weed species present in the field to be treated through scouting and field history. An understanding of weed biology is useful in designing a resistance management strategy. Ensure the weed management program will control all weeds present. • Fields should be scouted prior to application to determine species present and growth stage. Always apply this herbicide at the labeled rate and correct timing for the weeds present in the field. Utilize non-herbicidal practices to add diversity • Use diversified management tactics such as cover crops, mechanical weed control, harvest weed seed control, and crop rotation as appropriate. Use good agronomic practices, start clean and stay clean • Use good agronomic practices that enhance crop competitiveness. • Plant into weed-free fields utilizing tillage or an effective burndown herbicide for control of emerged weeds. • Sanitize farm equipment to avoid spreading seed or vegetative propagules prior to leaving fields. Difficult to control weeds • Fields with difficult to control weeds should be planted in rotation with crops that allow the use of herbicides with an alternative mode of action or different management practices. • Difficult to control weeds may require sequential applications, such as a broad spectrum preemergence herbicide followed by one or more postemergence herbicide applications. Utilize herbicides containing different modes of action effective on the target weeds in sequential applications. Do not overuse the technology • Do not use more than two applications of this or any other herbicide with the same mode of action in a single growing season unless mixed with an herbicide with a different mode of action which provides overlapping spectrum for the difficult to control weeds.

10 Scout and inspect fields following application • Prevent an influx of weeds into the field by controlling weeds in field borders. • Scout fields after application to verify that the treatment was effective. • Suspected herbicide resistant weeds may be identified by these indicators • Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds. • A spreading patch of non-controlled plants of a particular weed species. • Surviving plants mixed with controlled individuals of the same species. • Report non-performance of this product to your Syngenta retailer, Syngenta representative, or call 1-866-Syngent(a) (866-796-4368). If resistance is suspected ensure weed escapes are controlled using an herbicide with an effective mode of action and/or use non-chemical means to prevent further seed production. Prevent weed escapes before, during, and after harvest • Do not allow weed escapes to produce seed or vegetative structures such as tubers or stolons which contribute to spread and survival. Consider harvest weed seed management and control weeds post-harvest to prevent seed production. Resistant Weeds • Contact your local Syngenta representative, retailer, crop advisor or extension agent to determine if weeds resistant to modes of action contained in this product are present in your area. • Do not assume that each listed weed is being controlled by multiple modes of action. Premixes are intended to broaden the spectrum of weeds that are controlled. Some weeds may be controlled by only one of the active ingredients in this product. • If resistant biotypes have been reported, use the full labeled rate of this product, apply at the labeled timing, and tank-mix with an additional different mode of action product so there are multiple effective modes of application for each suspected resistant weed. 4.0 APPLICATION DIRECTIONS 4.1 Methods of Application Applications with A22670 alone or in tank mixtures are permitted by ground application only. Preplant, preemergence, and postemergence applications are allowed as specified in Section 9.0 unless otherwise restricted in Section 7.0. Refer to Section 4.5 for use of A22670 with dry bulk fertilizers.

4.2 Application Equipment • Configure spray equipment to provide accurate and uniform coverage of the target area and minimize potential for spray drift. • To ensure accuracy, calibrate sprayer before each use. • For information on spray equipment and calibration, consult spray equipment manufacturers and/or state recommendations.

11 • All ground application equipment must be properly maintained. • Spray nozzles should be uniformly spaced, the same size and type, and should provide accurate and uniform application. • Use spray nozzles that provide medium or coarser droplet size to avoid drift yet provide good coverage. • Ensure that all in line strainer and nozzle screens in the sprayer are 50-mesh or coarser. • Flat fan nozzles of 80° or 110° are recommended for optimum postemergence coverage. • Do not use floodjet nozzles or controlled droplet application equipment for postemergence applications. • Nozzles may be angled forward 45° to enhance penetration of the crop and provide better coverage with postemergence application. • Use a pump that can maintain the manufacturer’s recommended pressure at the nozzles and provide proper agitation within the tank to keep the product dispersed. • Lower pressures may be used with extended range or drift reduction nozzles as long as adequate coverage is maintained. • Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time. • If the agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying.

4.3 Application Volume and Spray Coverage • Good weed coverage is essential for optimum postemergence weed control. • Boom height for broadcast over-the-top applications must be based on the height of the ground or crop – at least 15 inches above the crop canopy, but no more than 4 feet above the ground or crop canopy. • For preemergence applications, apply in a spray volume of 10-80 gal/A. • For early postemergence applications, apply in a spray volume of 10-30 gal/A. When weed foliage is dense, use a minimum spray volume of 20 gal/A.

4.4 Mixing Directions

1. Thoroughly clean spray equipment before using this product. Dispose of the cleaning solution in a responsible manner. If water is used as the carrier, use clean water. Do not use a sprayer or applicator contaminated with other materials, or crop damage or sprayer clogging of the application device may occur.
2. Prepare no more spray mixture than is needed for the immediate operation.
3. Keep product container tightly closed when not in use.
4. Agitate the spray solution before and during application.
5. Do not let the spray mixture stand overnight in the spray tank.
6. Flush the spray equipment thoroughly following each use and apply the rinsate to a previously treated area.

4.4.1 A22670 Alone

1. For preemergence applications, either clean water or liquid fertilizer, excluding suspension fertilizers, may be used as carriers. If liquid fertilizer is used, conduct a

12 compatibility test to ensure mixture compatibility. 2. For postemergence applications, use only clean water as the carrier. 3. Provide sufficient agitation during mixing and application to maintain a uniform mixture. 4. Even if A22670 is physically compatible with a liquid fertilizer, constant agitation is necessary to maintain a uniform mixture during application. 5. Fill the spray tank ½ full with clean water or liquid fertilizer and add AMS (if used) while continuing agitation. 6. Add the specified amount of A22670 to the spray tank when the tank is half full of the carrier. 7. Add an adjuvant, if needed. 8. Complete filling the sprayer tank and continue agitation.

4.4.2 Tank-Mix Precautions • It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions, limitations and directions for use on all specified product labels involved in tank mixing. User must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. • Tank mixes of A22670 with other pesticides, fertilizers, or any other additives not specifically labelled for use with A22670 may result in tank mix incompatibility or unsatisfactory performance. In such cases, always check tank mix compatibility by conducting a jar test according to guidance in Section 4.4.3 before actual tank mixing.

4.4.3 Tank-Mix Compatibility • Conduct a jar test using a 1 pt to 1 qt container with lid by adding water or other intended carrier such a liquid fertilizer to the jar. • Next, add the appropriate amount of pesticides(s) or tank-mix partner(s) in their relative proportions based on specified label rates. Add tank-mix components separately in the order described in the tank-mixing section, Section 4.4.4. After each addition, shake or stir gently to thoroughly mix. • After all ingredients have been added, put the lid on the jar, tighten and invert the jar 10 times to mix. • After mixing, let the mixture stand 15–30 minutes and then examine for signs of incompatibility such as obvious separation, large flakes, precipitates, gels or heavy oily film on the jar. • If the mixture remains mixed or can be remixed readily, it is physically compatible and can be used. • If the mixture is incompatible, repeat the test using a compatibility agent at the specified label rate. Or, if applicable, slurry dry formulations in water before adding to the jar. If incompatibility is still observed after following these procedures, do not use the mixture. • After compatibility testing is complete, dispose of any pesticide wastes in accordance with the storage and disposal section, Section 10.0, of this label.

13 4.4.4 A22670 In Tank Mixtures

1. Fill the spray tank or premix tank half full with clean water or liquid fertilizer.
2. Use only clean water as the carrier if applying A22670 after crop emergence.
3. Begin tank agitation and continue constantly throughout mixing and spraying.
4. Prepare the components and add in the following order: a) If ammonium sulfate (AMS) is used, add slowly while continuing agitation until completely dispersed. b) If a wettable powder or dry flowable formulation is used, make a slurry with water and add it slowly through the screen into the tank. Agitate during the procedure. c) Mixing and compatibility may be improved when a dry flowable is diluted with water before adding to the tank. d) If a liquid formulation (excluding EC) is used, add slowly through screen into the tank. e) Add A22670. f) Add any other tank mix products next with emulsifiable concentrate (EC) products added last. g) Add an adjuvant last, if needed.
5. Complete filling the sprayer tank and continue agitation.
6. Apply as soon as possible after spray mixture is prepared.
7. Do not leave mixture in spray tank overnight without agitation or unattended.

If A22670 is added to the spray tank via induction, compatibility may be compromised. If an induction tank (or similar equipment) is used, add each product separately and allow each to disperse into the spray tank before adding the next product. For best tank-mix compatibility, rinse the induction tank with water before adding each component. To avoid mixing issues, do not add A22670 to the spray tank via in-line injection.

4.4.5 Spray Additives When an adjuvant is to be used with this product, the use of an adjuvant that meets the standards of the Chemical Producers and Distributors Association (CPDA) adjuvant certification program is recommended. • Where A22670 is applied after the corn has emerged, add a non-ionic surfactant (NIS) at 0.25% v/v (1 qt/100 gal of spray solution). • In addition to NIS, a spray grade ammonium sulfate (AMS) at 8.5-17 lb/100 gal of water may also be used. • When using liquid AMS products, use a rate that delivers an AMS equivalent of 8.5-17 lb/100 gal of water. • The use of crop oil concentrate (COC) may result in temporary crop injury. In severe cases, injury can persist and result in crop stunting. • Do not use methylated seed oil (MSO) or urea ammonium nitrate (UAN) with A22670 when applied alone to emerged corn, or when A22670 is applied as a postemergence tank mixture with other products, unless directed for a specific tank mix on this label or as part of a supplemental A22670 label.

14 • Any of these adjuvants may be used at a preemergence or preplant timing, i.e. where the corn crop has not yet emerged to increase burndown activity on existing weeds.

4.5 Dry Bulk Granular Fertilizers A22670 may be impregnated or coated onto dry bulk fertilizers including ammonium phosphate-sulfate, ammonium sulfate (AMS), diammonium phosphate (DAP), monoammonium phosphate (MAP), potash (potassium chloride), potassium sulfate, urea, or blends of these dry bulk fertilizer types.

When applying A22670 on dry bulk fertilizer, follow all directions for use and precautions on the product label regarding target crops, application rate, timing of application and all precautions and restrictions.

All individual state regulations relating to dry bulk granular fertilizer blending, registration, labeling, and application are the responsibility of the mixer and applicator.

4.5.1 Preparation of Herbicide/Fertilizer Mixtures • Prepare the fertilizer/herbicide mixture by using any closed drum, belt, ribbon, or other commonly used dry bulk fertilizer blender. • Nozzles used to spray A22670 onto the fertilizer must be placed to provide uniform spray coverage. • Care must be taken to aim the spray directly onto the fertilizer and avoid spraying the walls of the blender. • If the fertilizer/herbicide blend is too wet for uniform application, adding a drying agent is advised. • Add the drying agent slowly to the fertilizer/herbicide blend until the mixture is suitable for uniform application. • The amount of drying agent needed will depend on fertilizer type, A22670 application rate and amount of fertilizer used. • Apply the fertilizer/herbicide blend immediately following impregnation.

4.5.2 Precautions • TO AVOID POTENTIAL FOR EXPLOSION: do not impregnate A22670 onto ammonium nitrate, potassium nitrate, or sodium nitrate either alone or in blends with other fertilizers. • Do not impregnate A22670 onto single super phosphate or triple superphosphate fertilizers. • Do not impregnate A22670 on straight unadulterated agricultural limestone, since absorption will not be achieved.

4.5.3 Application of Herbicide/Fertilizer Mixtures • Apply a minimum of 200 lb of dry bulk fertilizer impregnated with A22670 at the specified broadcast rate per acre.

15 • For best results, apply the mixture uniformly to the soil with properly calibrated equipment immediately after blending. • Uniform application of the blended fertilizer/herbicide mixture is essential to prevent possible crop injury and achieve weed control. Non-uniform application will result in unsatisfactory weed control. • In areas where tillage is practiced, a shallow incorporation of the blended fertilizer/herbicide mixture is advised for improved weed control. Calculate amount of A22670 needed by the following formula:

2,000 X qt/A of = qt of A22670 lb of fertilizers per acre A22670 ton of fertilizer

4.5.4 Pneumatic (Compressed Air) Application • A22670 may be applied through pneumatic applicators, whether the fertilizer/herbicide mixture is blender-mixed or on-board fertilizer impregnation system. • A22670 must not be mixed with any other liquid or dry material in on-board fertilizer impregnation system tanks. • Use high quality fertilizer with a minimum of fines when applying A22670 with on-board impregnation equipment. • Drying agents are not advised for use with on-board impregnation systems.

4.6 Sprayer Cleanout Special attention must be given to cleaning equipment before spraying a crop other than corn. Mix only as much spray solution as needed.

1. Flush tank, hoses, boom, and nozzles with clean water.
2. Prepare a cleaning solution of 1 gal of household ammonia per 25 gal of water. Many commercial spray tank cleaners may be used.
3. Use a pressure washer to clean the inside of the spray tank with this solution. Take care to wash all parts of the tank, including the inside top surface. If a pressure washer is not available, completely fill the sprayer with the cleaning solution to ensure contact of the cleaning solution with all internal surfaces of the tank and plumbing. Start agitation in the sprayer and thoroughly recirculate the cleaning solution for at least 15 minutes. Remove all visible deposits from the spraying system.
4. Flush hoses, spray lines, and nozzles for at least 1 minute with the cleaning solution.
5. Dispose of rinsate from steps 1-4 in an appropriate manner.
6. Repeat steps 2-5.
7. Remove nozzles, screens, and strainers and clean separately in the ammonia solution after completing the above procedures.
8. Rinse the complete spraying system with clean water.

16 5.0 REPLANT AND ROTATIONAL CROPS When A22670 is applied as directed on this label, follow the crop replant/rotational intervals shown below. If A22670 is tank mixed with other products, follow the most restrictive product’s crop rotation interval. The replant/rotational interval is the time between the last application of A22670 and planting of the replant/rotational crop. Crop Replant/Rotational Interval Field corn Seed corn Yellow popcorn Sweet corn Anytime Small grain cereals including wheat, barley and rye 4 Months Alfalfa (see rotational crops use restrictions below) Cotton Dry beans (see rotational crops use restrictions below) Peanuts Potato Rice Soybeans Sorghum (all types) 10 Months All other rotational crops 18 Months ROTATIONAL CROPS USE PRECAUTIONS • If applied after June 1, rotating to crops other than corn (all types) may result in crop injury. ROTATIONAL CROPS USE RESTRICTIONS • DO NOT apply more than 3.0 qt of A22670 per year. • The 10 month rotation to alfalfa applies only when the total amount of A22670 applied was 2.7 qt/A. If more than 2.7 qt/A was applied, the alfalfa rotational interval is 18 months. • The 10 month rotational interval for dry beans applies only to areas west of US highway 83 in the states of Colorado and Nebraska where A22670 was applied to ground that was under center pivot irrigation and the soil pH is greater than 6.5. Otherwise the dry bean rotational interval is 18 months.

6.0 COVER CROPS A cover crop can be an important tool for the overall farm cropping system. Cover crops are planted for conservation purposes, soil erosion control, soil health improvement, water quality improvement and weed management. A cover crop can be a single crop or a combination of crops, including grasses and/or broadleaf crops. After harvest of a A22670 treated crop, planting of a cover crop is allowed provided the cover crop is not grazed or fed to livestock nor harvested for food. Terminate the cover crop through natural causes such as frost or intentional termination by herbicide application, crimping, rolling, tillage or cutting. All possible cover crops or cover crop combinations have not been tested for tolerance to this product. Before planting the cover crop, determine the level of tolerance for the intended cover crops by conducting a field bioassay. Refer to Section 6.1 for instructions on how to conduct a field bioassay.

17 6.1 Field Bioassay for Cover Crops A field bioassay is a method of determining if herbicide residues are present in the soil at concentrations high enough to adversely affect crop growth. Conduct the field bioassay by planting several strips of the desired cover crop across the field which has been previously treated with A22670. Plant the cover crop strips perpendicular to the direction of the product application. Locate the strips so that all the different field conditions are encountered, including differences in field terrain, soil texture, organic matter, pH, and drainage. If the cover crop does not show adverse effects such as crop injury and/or stand reduction, the field can be planted to this cover crop. If injury and/or stand reduction are visible, wait two to four weeks for further herbicide degradation to occur and repeat the bioassay. Alternatively, select a different cover crop and repeat the bioassay. Only plant cover crops that show acceptable tolerance in the field bioassay. 7.0 RESTRICTIONS AND PRECAUTIONS 7.1 Use Restrictions • DO NOT sell, use or distribute this product in Nassau and Suffolk Counties in the State of New York. • DO NOT apply this product through any type of irrigation system. • DO NOT apply by air. • DO NOT contaminate irrigation water used for crops or water used for domestic purposes.

7.2 Use Precautions • Avoid making applications under conditions which favor runoff or wind erosion of soil containing this product to non-target areas. • To prevent off-site movement due to runoff or wind erosion: o Avoid treating powdery dry or light sand soils when conditions are favorable for wind erosion. Under these conditions, the soil surface should first be settled by rainfall or irrigation. o Avoid making applications to impervious substrates, such as paved or highly compacted surfaces. o Avoid use of tail water from the first flood or furrow irrigation of treated fields to treat non-target crops, unless at least ½ inch of rainfall has occurred between application and the first irrigation. • Applied according to directions and under normal growing conditions, A22670 will not harm the treated crop. During germination and early stages of growth, extended periods of unusually cold and wet or hot and dry weather, insect or plant disease attack, carryover pesticide residues, the use of certain soil applied systemic insecticides, improperly placed fertilizers or soil insecticides may weaken crop seedlings. A22670 used under these conditions could result in crop injury.

18 7.3 Mandatory Spray Drift Management Ground Boom Applications • User must only apply with the release height recommended by the manufacturer, but no more than 4 feet above the ground or crop canopy. • Applicators are required to select the nozzles and pressure that deliver medium or coarser droplets (ASABE S572). • 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 select the nozzle and pressure that deliver medium or coarser droplet size (ASABE S572) for all applications. • Do not apply when wind speeds exceed 15 miles per hour at the application site. • Do not apply during temperature inversions.

7.4 SPRAY DRIFT ADVISORIES

THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.

7.4.1 Importance of Droplet Size • An effective way to reduce spray drift potential 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. 7.4.2 Controlling Droplet Size • 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.

7.4.3 Boom Height - Ground Boom • For ground equipment, the boom should remain level with the crop and have minimal bounce.

19 7.4.4 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. 7.4.5 Temperature and Humidity • When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.

7.4.6 Temperature Inversions Drift potential is high during a temperature inversion. Temperature inversions are characterized by increasing temperatures 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.

7.4.7 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. 7.4.8 Boomless Ground Applications • Setting nozzles at the lowest effective height will help to reduce the potential for spray drift. 7.4.9 Handheld Technology Applications Take precautions to minimize spray drift.

8.0 WEEDS CONTROLLED OR PARTIALLY CONTROLLED BY A22670

A22670 applied as directed in this label will control or suppress the weeds listed in Sections 8.1 and 8.2. Additional weeds may be controlled with tank mixes. See Section 9.1.2 for specified tank mix combinations. Always consult the tank mix product labels for specific rates and use directions.

20 PARTIAL WEED CONTROL Where reference is made to weeds partially controlled, partial control can either mean erratic control from good to poor or consistent control at a level below that generally considered acceptable for commercial weed control.

If irrigation is available, apply ½ to 1 inch of water. If irrigation is not available, a uniform shallow cultivation is advised as soon as weeds emerge or apply an appropriately labeled herbicide to control emerged weeds. • Should weeds develop after application, a shallow cultivation or rotary hoeing will generally result in improved weed control. If A22670 was incorporated, cultivate less than half the depth of incorporation. • If cultivation is necessary due to soil crusting, compaction, or escaped weeds, adjust equipment to run shallow and minimize soil movement. This will decrease the possibility of diluting or moving the herbicide from the weed control zone.

If the glyphosate product has a built-in adjuvant system (i.e. the product label does not ask for additional adjuvant), only spray-grade ammonium sulfate (AMS) at 8.5-17 lb/100 gal of spray solution may be added to this mixture. If the glyphosate product label calls for an adjuvant in addition to AMS, add a non-ionic surfactant (NIS) at 0.25% v/v and AMS to this spray mixture.

Do not add urea ammonium nitrate (UAN), crop oil concentrate (COC), or methylated seed oil (MSO) type adjuvants to these mixtures, or crop injury may occur. Early Postemergence in Glufosinate Resistant Corn Liberty

Apply A22670 at a rate of 1.5-2.0 qt/A to over-the-top in field corn designated as glufosinate resistant. Application to corn that is not glufosinate resistant will result in crop death.

To minimize weed competition with the crop, target the application of this mixture to weeds less than 3 inches in height.

Ammonium sulfate (AMS) may be added as a spray adjuvant as directed on the Liberty label. However, AMS must be the only adjuvant added to this tank mixture. Precaution: • All use precautions cited in Section 9.1.1 for A22670 solo apply to tank mixes with A22670. TANK-MIX USE RESTRICTIONS

1. All use restrictions cited in Section 9.1.1 for A22670 solo apply to tank mixes with A22670.
2. Do not make postemergence (emerged corn) applications of A22670 in a tank mix with any organophosphate or carbamate insecticide, or severe corn injury may occur.
3. Do not add urea ammonium nitrate (UAN), crop oil concentrate (COC), or methylated seed oil (MSO) type adjuvants to tank mixtures with glyphosate for early postemergence application in glyphosate resistant corn or with Liberty in glufosinate resistant corn, or crop injury may occur.

30 4) For all tank mixtures, refer to individual product labels for precautionary statements, restrictions, rates, approved uses, rotational restrictions and a list of weeds controlled. Follow the most restrictive label. 5) When tank mixing or sequentially applying atrazine or products containing atrazine with A22670 to corn, do not exceed an application rate of 2.0 lb ai/A for any single application and the total atrazine applied must not exceed 2.5 lb ai/A per year.
