4 4.50” 4.0625” 7.75” 7.375” COPY AREA COPY AREA PRODUCT INFORMATION DIFLEXX® Herbicide: • is a selective herbicide for the control of annual broadleaf weeds and control/ suppression of many biennial and perennial broadleaf weeds in corn (field corn, field corn grown for silage, white corn, seed corn, popcorn), and fallow croplands. • is formulated as a suspension concentrate containing 4 pounds acid equivalent of 3,6-dichloro-o-anisic acid (diglycolamine salt) and the new corn safener Cyprosulfamide. • is readily absorbed by leaves, shoots and roots, translocates throughout the plant, and accumulates in sensitive plant’s growing points. • controls weeds by affecting cell wall plasticity and nucleic acid metabolism leading to uncontrolled cell division and growth, ultimately causing vascular tissue destruction and plant death. • controls many broadleaf weed species which have developed herbicide resistance to glyphosate, triazine, PPO, ALS and HPPD chemistries. APPLICATION INSTRUCTIONS DIFLEXX Herbicide: • may be used in either conventional, conservation or no-till crop management systems. • may be applied to actively growing weeds using either broadcast, band or spot spray applications • may be applied using water as a carrier. • may be applied preplant, preemergence or post emergence. • may be applied at use rates of 6-64 fl oz/acre depending on crop, weed growth stages and weeds to be controlled/suppressed. o General rate information can be found in the APPLICATION RATES section of this label. Detailed rate information by crop can be found in the SPECIFIC USE DIRECTIONS section of this label. • may be tank mixed with adjuvants (refer to Spray Additives section of this label). • must be applied in a manner which minimizes/avoids herbicide drift to sensitive plants. o using coarse sprays (volume median diameter of 400 microns or more). Select nozzles that are designed to produce minimal amounts of fine spray particles (less than 200 microns). o keeping spray pressure at or below 20 psi and spray volume at or above 20 gallons per acre (for ground broadcast applications), unless otherwise required by the manufacturer of drift-reducing nozzles. Consult your spray nozzle supplier concerning the choice of drift-reducing nozzles. o using agriculturally-approved drift reducing additives. • must be applied in a manner such that weeds are thoroughly covered with spray. Ground Application (Banding) When applying DIFLEXX Herbicide by banding, determine the amount of herbicide and water volume needed using the following formula: band width (inches) row width (inches) X broadcast rate per acre = banding rate per acre band width (inches) row width (inches) X broadcast spray volume = banding spray volume per acre per acre Ground Application (Broadcast) • Ground application equipment must be properly maintained and calibrated using the appropriate carriers and spray additives. • Use 3 - 50 gallons of spray solution per broadcast acre for optimal performance. Use the higher spray volume when treating dense or tall vegetation.

5 4.50” 4.0625” 7.75” 7.375” COPY AREA COPY AREA • Select nozzles designed to produce minimal amounts of fine spray particles. Spray with nozzles as close to the weeds as is practical for good weed coverage. • Avoid spraying when conditions favor drift beyond the intended application area. Spray Additives DIFLEXX Herbicide is a suspension concentrate. To improve post emergence weed control, agriculturally approved surfactants may be added, particularly in dry growing conditions. Additive Products And Rates Adjuvant NIS (Nonionic Surfactant) (0.25% v/v or 1 qt/100 gallons) COC (1.0% v/v or 1 gal/100 gallons) MSO (1.0% v/v or 1 gal/100 gallons) USE RESTRICTIONS • Maximum Seasonal Use Rate: 24 - 64 fluid ounces per acre per year. Refer to the SPECIFIC USE DIRECTIONS section for each crop for detailed information. • Preharvest Interval (PHI): Refer to the SPECIFIC USE DIRECTIONS section for each crop for detailed information. • Restricted-Entry Interval (REI): 24 hours. • DO NOT apply to crops under stress due to lack of moisture, hail damage, flooding, herbicide damage, mechanical injury, insects or widely fluctuating temperatures as injury may result. • DO NOT apply through any type of irrigation equipment. • DO NOT treat irrigation ditches or water used for crop irrigation or domestic purposes. Refer to the specific use directions and restrictions in each Crop, Crop Group or Crop Subgroup table. USE PRECAUTIONS • Uneven Spray Coverage: To avoid uneven spray coverage, DIFLEXX Herbicide should not be applied during periods of gusty wind or when wind is in excess of 15 mph. • Off-Target Movement: DIFLEXX Herbicide may cause injury to desirable trees and plants, particularly beans, cotton, flowers, fruit trees, grapes, ornamentals, peas, potatoes, soybeans, sunflowers, tobacco, tomatoes, and other broadleaf plants when contacting their roots, stems or foliage. These plants are most sensitive to DIFLEXX Herbicide during their development or growing stage. • Disturbing Soil After Application: Disturbing DIFLEXX Herbicide (e.g. tillage or cultivating) treated areas within 7 days following an application may reduce herbicide uptake, translocation and weed control. • Rainfast Period: Rainfall or irrigation occurring within 4 hours after post emergence applications may reduce the effectiveness of DIFLEXX Herbicide. RESISTANCE MANAGEMENT This product is a Group 4 herbicide. A given weed population may contain or develop resistance to a herbicide after repeated use. Appropriate resistance- management strategies should be followed to mitigate or delay resistance. The following Integrated Weed Management Techniques are effective in reducing problems with herbicide resistant weed biotypes. It is best to use multiple practices to manage or delay resistance, as no single strategy is likely to be totally effective. • Rotate crops. Crop rotation diversifies weed management.

6 4.50” 4.0625” 7.75” 7.375” COPY AREA COPY AREA • Rotate herbicide-tolerant traits. Alternate herbicide-tolerant (HT) traits and/or use HT trait stacks for more efficient rotation. • Use multiple herbicide sites of action. Use tank mix partners and multiple SOAs during both the growing season and from year to year to reduce the selection pressure of a single SOA. • Know your weeds, know your fields. Closely monitor problematic areas with difficult-to-control weeds or dense weed populations. • Start with clean fields. Effective tillage or the use of a burndown herbicide program can control emerged weeds prior to planting. • Stay clean – use residual herbicides. Regardless of tillage system, pre- emergence or early post-emergence soil-applied residual herbicides should be used when possible. • Apply herbicides correctly. Ensure proper application, including timing, full use-rates and appropriate spray volumes. • Control weed escapes. Consider spot herbicide applications, row wicking, cultivation or hand removal of weeds or other techniques to stop weed seed production and improve weed management. • Zero tolerance – reduce the seed bank. Do not allow surviving weeds to set seed, which will help decrease weed populations from year to year and prevent major weed shifts. • Clean equipment. Prevent the spread of herbicide-resistant weeds and their seeds. Contact your local extension specialist, certified crop advisory and /or Bayer CropScience representative (1-844-RRXtend) for additional resistance management or IPM recommendation. Also for more information on Weed Resistance Management, visit the Herbicide Resistance Action Committee (HRAC) on the web at http://www.hracglobal.com. SPRAY DRIFT MANAGEMENT Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment and weather related factors determine the potential for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions. Where states have more stringent regulations, they must be observed. The applicator should be familiar with and take into account the information covered in the following Drift Reduction Advisory. [This information is advisory in nature and does not supersede mandatory label requirements.] Drift Reduction Advisory Information on 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. 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). 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 – Do not exceed the nozzle manufacturer’s recommended pressures. For many nozzle types, lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure. • Number of Nozzles – Use the minimum number of nozzles that provide uniform coverage.

7 4.50” 4.0625” 7.75” 7.375” COPY AREA COPY AREA • Nozzle Orientation – Orienting nozzles so that the spray is released parallel to the air stream produces larger droplets than other orientations and is the recommended practice. Significant deflection from horizontal will reduce droplet size and increase drift potential. • Nozzle Type - Use a nozzle that is designed for the intended application. With most nozzles types, narrower spray angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back produce the largest droplets and the lowest drift. Temperature and Humidity When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. Temperature Inversions Applications should not occur during a local, low level temperature inversion because drift potential is high. Temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud. This cloud can move in unpredictable directions due to the light variable winds common during inversions. Temperature inversions are characterized by increasing temperatures 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 the smoke from a ground source. 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 is lowest between wind speeds of 2 to 10 mph. However, many factors, including droplet size and equipment type, determine drift potential at any given speed. Application should be avoided below 2 mph due to variable wind direction and high inversion potential. Note: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. Sensitive Areas The pesticide should only be applied when the potential for drift to adjacent areas (e.g., residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal (e.g., when wind is blowing away from the sensitive areas). COMPATIBILITY TESTING AND TANK MIX PARTNERS Before mixing components, always perform a compatibility jar test. For 20 gallons per acre spray volume, use 3.3 cups (800 ml) of water. For other spray volumes, adjust accordingly. Only use water from the intended source at the source temperature. Add components in the sequence indicated in the Mixing Order Instructions section using 2 teaspoons for each pound or 1 teaspoon for each pint of label rate per acre. Always cap the jar and invert 10 cycles between component additions. When the components have all been added to the jar, let the solution stand for 15 minutes. Evaluate the solution for uniformity and stability. The spray solution should not have free oil on the surface, nor fine particles that precipitate to the bottom, nor thick (clabbered) texture. If the spray solution is not compatible, repeat the compatibility test with the addition of a suitable compatibility agent. If the solution is then compatible, use the compatibility agent as directed on its label. If the solution is still incompatible, DO NOT mix the ingredients in the same tank. Unless otherwise prohibited on this label or the label of an intended tank mix product, DIFLEXX Herbicide may be applied in combinations with any pesticide registered for the same crop, timing and method of application. See the SPECIFIC CROP USE RECOMMENDATIONS section for more details. 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 product labels involved in

8 4.50” 4.0625” 7.75” 7.375” COPY AREA COPY AREA tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. Order of Mixing DIFLEXX Herbicide may be used with other pesticides, fertilizers, and micronutrients. The proper mixing procedure for DIFLEXX Herbicide alone or in tank mix combinations with other pesticides is:

1. Water. Begin by agitating a thoroughly clean sprayer tank three-quarters full of clean water.
2. Agitation. Maintain constant agitation throughout mixing and application
3. Inductor. If an inductor is used, rinse it thoroughly after each component has been added.
4. 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 been dissolved and the product is evenly mixed in the spray tank before continuing.
5. Add DIFLEXX Herbicide and other water-dispersible products (dry flowables, wettable powders, suspension concentrates, or suspoemulsions)
6. Water-soluble products.
7. Emulsifiable concentrates (such as oil concentrate when applicable).
8. Water-soluble additives.
9. Remaining quantity of water. Maintain constant agitation during application. Equipment Cleanup Procedures To avoid injury or exposure to non-target crops, thoroughly clean all mixing and spray equipment, including pumps, nozzles, lines and screens, by using a strong detergent or commercial sprayer cleaner according to the manufacturer’s directions, and then triple rinsing the equipment before and after spraying this product. ROTATIONAL CROPS The interval between application and planting rotational crops is given below. Always exclude counting days when the ground is frozen. Planting at intervals less than specified below may result in crop injury. Moisture is essential for the degradations of this herbicide in soil. If dry weather prevails, use cultivation to allow herbicide contact with moist soil. • Planting/replanting restrictions for DIFLEXX Herbicide applications of 24 fluid ounces per acre or less: Corn can be replanted immediately following an application of DIFLEXX Herbicide (care should be taken that corn seed does not come into direct contact with the herbicide). The rotation interval to soybean varies by DIFLEXX Herbicide rate. For DIFLEXX Herbicide rates of 12 fluid ounces per acre or less, the rotational interval for soybeans is 30 days; for DIFLEXX Herbicide rates from 13 - 24 fluid ounces per acre, the soybean rotational interval is 60 days. The rotational interval is 60 days for barley, cotton, oat, sorghum, and wheat and 120 days for all other crops. • Planting/replanting restrictions for DIFLEXX Herbicide applications of more than 24 fluid ounces and up to 64 fluid ounces per acre: Corn, sorghum, cotton (east of Rocky Mountains) and all other crops grown in areas with 30” or more of annual rainfall may be planted 120 days or more after application. Barley, oat, wheat and other grass seedlings grown east of the Mississippi River may be planted 60, 90 and 120 days following DIFLEXX Herbicide application rates of 24-32, 33-48, and 49-64 fluid ounces/acre, respectively. Barley, oat, wheat and other grass seedlings grown west of the Mississippi River may be planted 60, 90, 135 and 180 days following DIFLEXX Herbicide application rates of 16, 17-32, 33-48, and 49-64 fluid ounces/acre, respectively. For all other crops in areas with less than 30” of annual rainfall, the interval between application and planting is 180 days or more.

9 4.50” 4.0625” 7.75” 7.375” COPY AREA COPY AREA Cover Crops Use of cover crops as a means of soil improvement, erosion control, weed and/or insect suppression, etc., following harvest of corn in the Fall is increasing. Planting of cover crops in fields treated with DIFLEXX Herbicide is allowed as long as these cover crops are not grazed by livestock nor harvested for food. Cover crops are to be tilled under or chemically controlled with burndown herbicides in the spring. Many cover crops can be planted within 90-120 days after application of DIFLEXX Herbicide. However, all potential cover crops have not been evaluated for tolerance to DIFLEXX Herbicide and significant injury may occur. Prior to seeding a cover crop, complete a successful field/small scale bioassay to provide an indication of the level of tolerance to the prior DIFLEXX Herbicide application. Refer to the “Field/Small Scale Bioassay” section. If used in tank mixtures with other herbicides, always follow the most restrictive label. Field/Small Scale Bioassay A field/small scale bioassay must be completed before rotating to a crop other than those specified in the Rotational Crop section of this label. To conduct an effective field bioassay, grow strips of the crop(s) you intend to grow in the following season in a field previously treated with DIFLEXX Herbicide. The test strip should be placed in a controlled area and should include low areas and knolls, and include variations in soil such as type and pH. Crop response to the bioassay will determine if the crop(s) grown in the test strips can be grown safely in the areas previously treated with DIFLEXX Herbicide. For an effective small scale bioassay, collect uniform samples of all soil types from the DIFLEXX Herbicide-treated field (see example above for types of soil in the sample) and place the soil into a sturdy container. Plant the desired cover crop into the soil, apply water and place the container in a warm sunny area to allow germination and growth of the crop. Monitor growth of the cover crop over a three to four week period. If the crop emerges and grows normally, the risk to establish and grow the cover crop in the DIFLEXX Herbicide-treated field should be tolerable. APPLICATION RATES DIFLEXX Herbicide will control/suppress many annual, biennial and perennial broadleaf weeds at rates ranging from 6 to 32 fluid ounces per acre. Small, actively growing annual weeds (1-3 inches tall) or small rosette growth stage biennial weeds (1-3 inch diameter) are generally more easily controlled/ suppressed than larger annual/biennial weeds or perennial weeds. For the list of weeds controlled/suppressed by DIFLEXX Herbicide, refer to the WEEDS CONTROLLED section of this label. For specific use rates recommendations per crop, refer to the SPECIFIC USE DIRECTIONS section of the label.

11 4.50” 4.0625” 7.75” 7.375” COPY AREA COPY AREA SPECIFIC USE DIRECTIONS CORN (Field, Pop, Seed, and Silage) USE DIRECTIONS DIFLEXX Herbicide can be applied pre-plant, pre-emergence, and post-emergence in corn for all tillage systems (e.g. no-tillage, reduced tillage and conventional). Plant corn at least 1 1/2 inches deep. Corn seed must be completely covered with soil and furrow firmed. In rare instances, applications of DIFLEXX Herbicide during periods of rapid corn growth may result in temporary leaning of the crop. Corn will usually become erect within 3-7 days. Cultivation should be delayed until after corn is growing normally to avoid potential stalk breakage. Before applying DIFLEXX Herbicide to seed corn or popcorn, verify the selectivity of DIFLEXX Herbicide on the inbred line or hybrid with your local seed corn or popcorn company (supplier). This precaution will help avoid potential injury to sensitive lines. APPLICATION RATE Do not apply more than 16 fluid ounces (0.5 lb dicamba ae) per acre per application and a total of 24 fluid ounces (0.75 lb dicamba ae) per acre per year. Apply a maximum of two applications per growing season. Sequential applications must be separated by two (2) weeks or more. Preplant and Preemergence Applications in No Tillage, Reduced Tillage and Conventional Corn Apply from 8 - 16 fluid ounces per acre of DIFLEXX Herbicide. Use the higher rates in the rate range on soils high in organic matter or under certain weed conditions (See higher rate recommendations listed under the Post-emergence Application in All Tillage Systems section. Post-emergence Application in All Tillage Systems Apply from 6 - 16 fluid ounces per acre of DIFLEXX Herbicide. Use higher rates in this range when one or more of the following situations are present: • Weeds with known resistance (ALS, PPO, glyphosate, triazine, HPPD, etc.) to herbicides in tank mix with DIFLEXX Herbicide • Weeds not controlled by tank mix partners • Heavy weed populations • Biennial/perennial weeds listed on the label • Annual weeds taller than 6” DIFLEXX Herbicide at rates below 8 fluid ounces per acre will provide control/ suppression of certain broadleaf weeds but should be applied in tank mixture with additional effective postemergence herbicides for improved weed control. APPLICATION TIMING Preplant and Preemergence Applications in No Tillage, Reduced Tillage and Conventional Corn DIFLEXX Herbicide can be applied up to 14 days before, during or after planting a corn crop. DIFLEXX Herbicide will control emerged labeled weeds and provide residual control of many weeds. When additional residual control is desired, a tank mixture with residual herbicides such as Corvus ®, Balance® Flexx, atrazine or other registered residual herbicides may be used. COC or MSO at 1%v/v are recommended for burndown of labeled weeds 6” or less in height. When weeds are greater than 6” in height or weeds not controlled by DIFLEXX Herbicide are present, the addition of a burndown herbicide (e.g., glyphosate) is recommended. Observe directions for use, precautions and restrictions, and adjuvants on the label of the residual or burndown tank mixed herbicides.

12 4.50” 4.0625” 7.75” 7.375” COPY AREA COPY AREA Post-emergence Application in All Tillage Systems Broadcast Spray Application: Apply DIFLEXX Herbicide as a broadcast spray when corn is at spike through the V10 stage of growth (10 leaf collar) or 36” tall, whichever occurs first. Early post emergence application is recommended for best weed control (weeds less than 3” tall) and crop yield potential. TANK MIX INSTRUCTIONS DIFLEXX Herbicide should be a part of an integrated pest control program that may include herbicides, insecticides and/or fungicides applied prior to, in tank mix with, or following a DIFLEXX Herbicide application. When using tank mix or sequential applications with DIFLEXX Herbicide, always follow the companion product label to determine specific use rates, application timings and pest controlled. In addition, follow precautions and restrictions including state and local use restrictions that may apply to specific products. 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 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. Possible tank mix partners with DIFLEXX Herbicide may include but are not limited to the following herbicides: Possible Tank Mix Partners for Additional Weed Control Autumn™ Super 51WDG Capreno® Glyphosate (Roundup Ready® corn hybrids only) Balance® Flexx Corvus® Laudis® Tank Mixtures for Disease Control To provide weed and disease control in corn, possible sequential or tank mix partners with DIFLEXX Herbicide may include but are not limited to the following fungicides: Prosaro®, Stratego® YLD Tank Mixtures for Insect Control To provide weed and insect control in corn, DIFLEXX Herbicide may be used sequentially with all soil-applied insecticides or used sequentially or in tank mix with most foliar-applied insecticides including Baythroid® XL, Oberon®, and other registered foliar insecticides. DO NOT apply DIFLEXX Herbicide in tank mixtures with Lorsban® /chlorpyrifos insecticide. If DIFLEXX Herbicide is used sequentially with foliar insecticides, applications should be separated by at least 7 days. RESTRICTIONS FOR USE • Do Not use on sweet corn. • Do Not apply more than 16 fluid ounces per acre per application and a total of 24 fluid ounces per acre per year. • Do Not use sprayable fluid fertilizer as the carrier for application of DIFLEXX Herbicide made after corn emergence. • Do Not apply DIFLEXX Herbicide when soybeans are growing nearby if any of these conditions exist: o Corn is more than 24” tall o Soybean are more than 10” tall o Soybean have begun to bloom • Preharvest Interval: Corn forage may not be harvested within 45 days of the final DIFLEXX Herbicide application. Corn grain and stover may be harvested once the crop has reached the ensilage (milk) stage.

13 4.50” 4.0625” 7.75” 7.375” COPY AREA COPY AREA FALLOW (BETWEEN CROP APPLICATIONS) USE DIRECTIONS DIFLEXX Herbicide can be applied either postharvest in the fall, spring, or summer during the fallow period or to crop stubble/set-aside acres. Apply DIFLEXX Herbicide as a broadcast or spot treatment to emerged and actively growing weeds after the crop harvest (postharvest) and before a killing frost or in the fallow cropland or crop stubble the following spring or summer. See the ROTATIONAL CROP section of the label for the required interval between application and planting to prevent crop injury. APPLICATION RATE Apply 4 - 32 fluid ounces of DIFLEXX Herbicide per acre. Refer to the APPLICATION RATES and WEEDS CONTROLLED sections of this label to determine use rates for specific targeted weed species. APPLICATION TIMING For best performance, apply DIFLEXX Herbicide when annual weeds are less than 3” tall, when biennial weeds are in the rosette stage and to perennial weed regrowth in late summer or fall following a mowing or tillage treatment. The most effective control of upright perennial broadleaf weeds such as Canada thistle and Jerusalem artichoke occurs if DIFLEXX Herbicide is applied when the majority of weeds have at least 4” - 6” regrowth or for weeds such as field bindweed and hedge bindweed that are in or beyond the full bloom stage. Avoid disturbing treated areas following application. Treatments may not kill weeds that develop from seed or underground plant parts such as rhizomes or bulblets, after the effective period for DIFLEXX Herbicide. For seedling control, a follow-up program or other cultural practices could be instituted.
