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.

Ground Water Advisory

Bicyclopyrone, mesotrione and S-metolachlor are known to leach through soil into ground water under certain conditions as a result of label use. These chemicals may leach into ground water if used in areas where soils are permeable, particularly where the water table is shallow.

4

Surface Water Advisory

This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining soils and soils with shallow ground water. This product is classified as having high potential for reaching surface water via runoff for several 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 S-metolachlor and mesotrione 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.

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.

Reporting Ecological Incidents

To report ecological incidents, including mortality, injury, or harm to plants and animals, call 1-800-888-8372.

PRODUCT INFORMATION

Acuron Flexi is labeled for use in field corn, silage corn, seed corn, yellow popcorn, and sweet corn for control of many annual grass and broadleaf weeds. Acuron Flexi is a combination of the herbicides bicyclopyrone, mesotrione and S-metolachlor plus the safener benoxacor.

Table 1. Acuron Flexi Application Methods

Crop Acuron Flexi Application Method Field Corn Preplant1, Preemergence and Postemergence Silage Corn Preplant1, Preemergence and Postemergence Seed Corn Preplant1, Preemergence and Postemergence Yellow Popcorn Preplant and Preemergence Sweet Corn Preplant and Preemergence 1Apply up to 28 days prior to planting

See Tables 2 and 3 for a list of weeds controlled. Apply this product prior to weed emergence to effectively control most grass weeds.

Applied according to use directions and under normal growing conditions, Acuron Flexi 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. Acuron Flexi used under these conditions can result in crop injury.

ACURON FLEXI USE PRECAUTIONS

x Applied according to directions and under normal growing conditions, Acuron Flexi 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

9

insecticides, improperly placed fertilizers or soil insecticides may weaken crop seedlings. Acuron Flexi used under these conditions could result in crop injury.

x 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.

x Dry weather following preemergence application of Acuron Flexi applied alone or in tank mixture may reduce effectiveness. If possible, cultivate if weeds develop.

x Applying Acuron Flexi postemergence to corn that has received an at-planting application of Counter® insecticide can result in severe corn injury. x Temporary corn injury may occur if Acuron Flexi is applied postemergence to corn that has received and at planting application of an organophosphate insecticides other than Counter.

x Postemergence (emerged corn) applications of any organophosphate or carbamate insecticide within 7 days before or 7 days after an Acuron Flexi application may result in severe corn injury.

ACURON FLEXI USE RESTRICTIONS

WEED RESISTANCE MANAGEMENT

Naturally occurring biotypes of certain weed species with resistance to triazines, ALS, PPO, Glycine (glyphosate) and HPPD 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 Tables 2 and 3.

To reduce the risk of weeds developing resistance to HPPD inhibitors, 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.

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.

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

Acuron Flexi may be integrated into an overall weed and pest management strategy. Utilize practices known to reduce weed development (tillage, crop competition) and herbicide use (weed scouting, proper application timing, banding and rotations) wherever possible. Consult local agricultural and weed specialist for additional Integrated Pest Management strategies established for your area.

Principles of Herbicide Weed Resistance Management Scout and know your field x 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. x Fields should be scouted prior to application to determine species present and growth stage. Always apply this herbicide at the full labeled rate and correct timing for the weeds present in the field.

12

Utilize non-herbicidal practices to add diversity x 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 x Use good agronomic practices that enhance crop competitiveness. x Plant into weed-free fields utilizing til lage or an effective burndown herbicide for control of emerged weeds. x Sanitize farm equipment to avoid spreading seed or vegetative propagules prior to leaving fields. Difficult to control weeds x 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. x 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 x Do not use this or any other herbicide wit h 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. Scout and inspect fields following application x Prevent an influx of weeds into the fie ld by controlling weeds in field borders. x Scout fields after application to verify that the treatment was effective. x Suspected herbicide-resistant weeds may be identified by these indicators a. Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; b. A spreading patch of non-controlled pl ants of a particular weed species; and c. Surviving plants mixed with controll ed individuals of the same species. x 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

13

x 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 x 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. x 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. x 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. APPLICATION INFORMATION

GROUND APPLICATION

Use spray nozzles of the same type and size that are evenly spaced to provide accurate and uniform application.

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, resuspend the spray solution by running on full agitation prior to spraying.

PREPLANT/PREEMERGENCE APPLICATION

Apply Acuron Flexi preplant (up to 28 days prior to corn planting) or preemergence with a carrier volume of 10-80 gal/A.

POSTEMERGENCE APPLICATION

Use only clean water as a carrier and apply in a spray volume of 10-30 gal/A. Good weed coverage is essential for optimum weed control. When weed foliage is dense, a higher application volume may be required to achieve optimum spray coverage.

AERIAL APPLICATION

Do not use aerial application to apply Acuron Flexi.

MANDATORY SPRAY DRIFT MANAGEMENT

Ground Boom Applications:

14

x Do not release spray at a height greater than 3 ft above the ground or crop canopy. x Applicators are required to select the nozzles and pressure that deliver medium or coarser droplet size in accordance with American Society of Agricultural & Biological Engineers Standard 572 (ASABE S572.1). x Do not apply when wind speeds exceed 15 mph at the application site. x 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 in accordance with American Society of Agricultural & Biological Engineers Standard 572 (ASABE S572.3). • Do not apply when wind speeds exceed 15 miles per hour 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 NON-TARGET SITES AND ENVIROMENTAL CONDITIONS.

Importance of Droplet Size • An effective way to reduce spray dr ift 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 x 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. x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift.

Boom Height - Ground Boom x Use the lowest boom height that is comp atible with the spray nozzles that will provide uniform coverage. x For ground equipment, the boom should remain level with the crop and have minimal bounce.

Shielded Sprayers x 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.

15

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

Temperature Inversions x Drift potential is high during a temperature inversion. x Temperature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. x 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. x 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. x Avoid applications during temperature inversions.

Wind x Drift potential generally in creases with wind speed. x AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. x Applicators need to be familiar with loca l wind patterns and terrain that could affect spray drift.

Boomless Ground Applications: x Setting nozzles at the lowest effective he ight will help to reduce the potential for spray drift.

Handheld Technology Applications x Take precautions to minimize drift. Cleaning Equipment After Application

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

16

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 1-3 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.

ADDITIVES

When an adjuvant is to be used with this product, use an adjuvant that meets the standards of the Chemical Producers and Distributors Association (CPDA) adjuvant certification program.

Where Acuron Flexi is applied after the corn has emerged, a non-ionic surfactant (NIS) at 0.25% v/v (1 qt/100 gal) may be used. The use of crop oil concentrate (COC) may result in temporary crop injury. If used, add COC at a rate not to exceed 1% v/v (1 gal/100 gal) or not more than the equivalent of 1 qt/A. Do not use nitrogen based adjuvants (AMS or UAN) or methylated seed oil (MSO) with Acuron Flexi when applied alone to emerged corn, or when Acuron Flexi 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 Acuron Flexi label. 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. Do not apply Acuron Flexi to emerged sweet corn or yellow popcorn or severe crop injury may occur.

Sprinkler Irrigation: Do not apply Acuron Flexi by sprinkler irrigation. Use a sprinkler system only to incorporate Acuron Flexi after application. After Acuron Flexi has been applied, a sprinkler irrigation system set to deliver ½-1 inch of water may be used to incorporate the product. Using more than 1 inch of water could result in reduced performance. On sandy soil low in organic matter, use no more than ½ inch of water. Do not use flood irrigation to apply or incorporate Acuron Flexi.

APPLICATIONS PRIOR TO CORN EMERGENCE (REFER TO TABLE 1 FOR CORN TYPES)

Any adjuvants may be used at a preemergence or preplant timing, (i.e. where the corn

17

crop has not yet emerged) to increase burndown activity on existing weeds. However, the best additives for weed control with Acuron Flexi are non-ionic surfactant at 1 qt/100 gal (0.25% v/v) plus an ammonium sulfate (AMS) product that delivers the equivalent of 8.5-17 lb/100 gal.

APPLICATIONS AFTER CORN HAS EMERGED (REFER TO TABLE 1 FOR CORN TYPES)

When applying Acuron Flexi postemergence to corn, add a non-ionic surfactant (NIS) at 1 qt/100 gal (0.25% v/v). Using additives other than non-ionic surfactant may result in lower levels of weed control and an increased risk of crop injury.

In addition to NIS, an ammonium sulfate (AMS) product that delivers the equivalent of at 8.5-17 lb/100 gal may also be added. The use of liquid nitrogen based adjuvants (e.g., UAN) will increase the risk of crop injury.

Do not use methylated seed oil (MSO) with Acuron Flexi applied alone or in tank mixture to emerged corn.

MIXING PROCEDURES

Either water or liquid fertilizers (excluding suspension fertilizers) may be used as carriers for preemergence applications. If fluid fertilizers are used, conduct a compatibility test prior to mixing and applying this product. Even if Acuron Flexi is physically compatible with a fluid fertilizer, constant agitation is necessary to maintain a uniform mixture during application. Use only clean water as the carrier when applying Acuron Flexi after crop emergence.

The spray tank must be clean, thoroughly rinsed and decontaminated before adding either Acuron Flexi alone or with tank-mix partners. If water is used as the carrier, use clean water.

Always refer to labels of other pesticide products for mixing directions and precautions which may differ from those outlined here. Use in accordance with the most restrictive label limitations and precautions. This product cannot be mixed with any product containing a label prohibition against such mixing. Do not tank mix Acuron Flexi with any other insecticide, fungicide, fertilizer solution, or adjuvant not on this label without testing compatibility, as poor mixing may result. Determine the compatibility of any tank-mix combination by conducting a small scale test such as a jar test before actual tank mixing.

USE THE FOLLOWING MIXING INSTRUCTIONS FOR ADDING ACURON FLEXI TO THE SPRAY TANK

1. Only use sprayers in good operating condition with adequate agitation. Ensure the sprayer is cleaned according to instructions on label of the product used prior

18

to use of Acuron Flexi.

2. Begin to fill sprayer tank or premix tank with clean water and engage agitator. Agitation must be continued throughout the entire mixing and spraying procedure.

3. When the sprayer or premix tank is half full of water, begin to add the mixture components.

4. If ammonium sulfate (AMS) is used, add slowly and continue agitation until completely dispersed.

5. If a wettable powder or dry flowable formulation is used, add it slowly to the tank. Mixing and compatibility may be improved when a wettable powder or dry flowable is diluted with water before adding to the tank. Agitate during the procedure.

6. If a flowable formulation is used, add slowly to the tank.

7. Add Acuron Flexi slowly to the tank.

8. Add any other liquid tank-mix products next with emulsifiable concentrates last.

9. Add an adjuvant last, if needed.

10. Complete filling the sprayer tank and continue agitation.

11. Apply as soon as possible after spray mi xture is prepared. Do not leave mixture in spray tank overnight without agitation.

If Acuron Flexi 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 Acuron Flexi to the spray tank via in-line injection.

COMPATIBILITY TEST

Conduct a jar test (1 pt to 1 qt container) before tank mixing to ensure compatibility of Acuron Flexi with liquid fertilizers or other pesticides. Start by adding the intended carrier (water or liquid fertilizer) to the jar. Next, add the appropriate amount of pesticide(s) in their relative proportions based on recommended label rates. If more than one pesticide is used, add them separately as described in the Mixing Procedures section of this label. After each addition, shake or stir gently to thoroughly mix.

19

After adding all ingredients, put a lid on the jar, tighten, and invert each jar 10 times to mix. Let the mixtures stand 15-30 minutes and then examine for separation, large flakes, precipitates, gels, heavy oily film on the jar, or other signs of incompatibility. If the mixture separates but can be remixed readily, the mixture can be sprayed as long as good agitation is used.

If the mixtures are incompatible, repeat the test using a compatibility agent at the recommended rate. If incompatibility is still observed, do not use the mixture.

EQUIPMENT CLEANING PROCEDURE

Prior to use of Acuron Flexi, follow the cleanup procedures specified on the label of the product(s) previously sprayed. If no instructions are provided, follow the instructions below.

To avoid subsequent crop injury, following the last application of Acuron Flexi, thoroughly clean all mixing and spray equipment per the instructions below.

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 insi de 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. Remove boom end caps and flush dead space areas, with water, then replace caps.

6. Dispose of rinsate from steps 1-5 in an appropriate manner, according to all local State and Federal regulations.

7. Repeat steps 2-6.

8. Remove nozzles, screens, and strainers and clean separately in the ammonia solution after completing the above procedures.

9. Rinse the complete spraying system with clean water.

20

WEEDS CONTROLLED

Acuron Flexi applied as directed in this label will control or partially control the weeds listed in Tables 2 and 3. Optimum weed control will be obtained if Acuron Flexi is applied according to all label directions.

If a significant rainfall does not occur within 7 days following a preemergence application, weed control may be decreased.

When weeds are stressed or not actively growing due to drought, heat, lack of fertility, flooding, or prolonged cool temperatures, postemergence control can be reduced or delayed.

CORN USE DIRECTIONS – ACURON FLEXI ALONE

Apply Acuron Flexi for preemergence control of many annual grass and broadleaf weeds in field corn, silage corn, seed corn, sweet corn and yellow popcorn. Acuron Flexi may also be applied early postemergence for the control of broadleaf weeds in field corn, silage corn and seed corn. Do not apply Acuron Flexi to yellow popcorn or sweet corn after the crop has emerged, or crop injury may occur. Refer to Tables 2 and 3 for a list or weeds controlled or partially controlled by Acuron Flexi.

ACURON FLEXI USE RATES

Apply Acuron Flexi preemergence or postemergence at a rate of 2.0-2.25 qt/A for control or partial control of the weeds listed in Tables 2 and 3. The application rate is based on the soil organic matter content of the field on which Acuron Flexi is to be applied. Acuron Flexi may also be applied as a split application. Refer to the split application section for directions.

Table 5. Acuron Flexi Use Rates in Corn

% Organic Matter Acuron Flexi Use Rate <3% 2.0 qt/A

3% 2.25 qt/A

Acuron Flexi is not recommended on soils with greater than 10% organic matter or poor weed control may result.

BURNDOWN FOR REDUCED AND NO TILLAGE SITUATIONS

In reduced or no-till corn and before the crop has emerged, Acuron Flexi can be applied alone or in tank mixture with Gramoxone® brands, Touchdown® brands, Roundup® brands or other registered herbicides for burndown of existing weeds. Refer to Tables 2 and 3 for specific weeds controlled by Acuron Flexi. Read and follow all product labels for specific use directions and information on weeds controlled. Refer to the ADDITIVES and TANK MIX sections on this label for additional instructions.

EARLY PREPLANT AND PREEMERGENCE

Acuron Flexi may be applied early preplant (up to 28 days prior to planting) or preemergence in field corn, silage corn, seed corn, sweet corn and yellow popcorn.

26

POSTEMERGENCE

Acuron Flexi may be applied in field corn, silage corn or seed corn after emergence until the plants reach 30 inches in height or up to the 8-leaf stage of corn growth. Use only clean water as the carrier when applying Acuron Flexi after crop emergence. Do not apply postemergence in liquid fertilizer or severe crop injury will occur. Do not apply Acuron Flexi to emerged yellow popcorn or sweet corn, or severe crop injury may occur. Refer to the ADDITIVES section on this label for burndown adjuvant directions.

SPLIT APPLICATION

Acuron Flexi may be applied as a split application in corn (for grain, silage or seed). For a split application program, apply ½ to ⅔ of the labeled rate of Acuron Flexi prior to crop emergence followed by a second Acuron Flexi application at ⅓ to ½ of the labeled rate as a post application after corn emergence. The total amount of Acuron Flexi applied in the split application program cannot exceed 2.25 qt/A in soils with <3% OM and cannot exceed 2.25 qt/A in soils with ≥3% OM. Refer to the Early Postemergence section above for instructions on postemergence applications.

ACURON FLEXI PROGRAMS IN GLYPHOSATE TOLERANT CORN

Acuron Flexi may be applied early postemergence at a rate of 1.25-2.0 qt/A for soils with <3% organic matter content and a rate of 1.25-2.25 qt/A for soils with >3% organic matter content in a tank mixture with a solo glyphosate product (e.g. Touchdown or Roundup brands) that is registered for use over-the-top in glyphosate tolerant field corn (e.g. Roundup Ready or Agrisure® GT Corn). To minimize weed competition with the crop, target the application of this mixture to weeds in the 1 to 2 inches tall. If the glyphosate product has a built-in adjuvant system (i.e. the product label does not ask for additional adjuvant), spray-grade ammonium sulfate (AMS) may be added at 8.5 lb/100 gal 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. Read and follow all directions for use and restrictions on the glyphosate product label.

28

Alternatively, Acuron Flexi may be applied preemergence to glyphosate tolerant corn (e.g. Roundup Ready or Agrisure GT Corn) at a rate of 1.35-2.0 qt/A (soils with <3% organic matter) or a rate of 1.5-2.25 (soils with >3% organic matter) as part of a two- pass weed control system when followed by a postemergence application of a glyphosate based product. When used in this way, Acuron Flexi will provide reduced competition of the weeds listed in Table 2 for a period of 30 or more days, thus improving the timing flexibility and effectiveness of the glyphosate based product application. Read and follow all directions for use and restrictions on the glyphosate product label.

Acuron Flexi may be applied preemergence to glyphosate tolerant corn (e.g. Roundup Ready or Agrisure GT Corn) at 1.0-1.2 qt/A as part of a two-pass weed control system when followed by Halex® GT. Apply Acuron Flexi at 1.0 qt/A on soils with <3% OM and 1.2 qt/A on soils with >3% OM. Read and follow all directions for use and restrictions on each product label.
