In addition; consult with your local DuPont representative or th,e DuPont Label Web Site (http://cropprotection.dupont.com/) for any additional supplemental labe^ing'infprmatific relative to potential corn hybrid sensitivity to DPX-121. cccccc c Lcc1' U C Timing to Crop cccccc DPX-121 may be applied preplan! in early spring up to planting, whenever the ground is not froz£u£tbccpntrol efh'efged weeds and to provide limited residual control of early-emerging weeds. octet, c • Additionally, DPX-121 may be applied anytime after planting, but before corn emergence. 'j c u 11 <_ Do not apply postemergence to corn. c . Control of emerged weeds will require the addition of spray adjuvants as noted in this label. c t t L L 'c Additional Control of Grasses and Broadleaves DPX-121 may be tank mixed with full or reduced rates of labeled preplant/preemergence grass and broadleaf herbicides such as atrazine, DuPont™ CINCH® brands and DuPont™ BREAKFREE® brands to provide added residual activity or additional burndown activity on emerged weeds. Sequential applications of PREQUEL™, CINCH® brands and r cDuPont™ BREAKFREE® brands may also be made following preplan! applications of DuPont™ DPX-121. Consult tank mix partner labeling for rate and soil-type restrictions. Sequential Application DPX-121 may be used in a sequential herbicide program for corn. Apply DPX - 121 for burndown and residual weed control, followed by a post, in-crop application of DuPont™ REALM™ Q, DuPont™ RESOLVE® Q or DuPont™ STEADFAST® Q herbicides. Refer to the appropriate product label for use restrictions, appb'cation information, rotational crop guidelines, and cautionary statements prior to application. If following DPX 121 with another rimsulfuron containing product such as DuPont™ PREQUEL®, REALM® Q, RESOLVE® Q or STEADFAST®, only plant corn, potatoes or soybeans the following season. SPRAY ADJUVANTS For control of emerged weeds, application of DPX-121 must contain an appropriate adjuvant. When applied in tank mix combination with a glyphosate (such as ABUNDIT® Extra) or glufosinate herbicide that contains a built-in adjuvant system, no additional surfactant needs to be added. Consult local DuPont fact sheets, technical bulletins, and service .policies prior to using other adjuvant systems. Products must contain only EPA-exempt ingredients. Petroleum Crop Oil Concentrate (COC) or Modified Seed Oil (MSO) •• Apply at 1% v/v (1 gallon per 100 gallons spray solution) or 2% under arid conditions. • MSO adjuvants may be used at 0.5% v/v (0.5 gallon per 100 gallons spray solution) if specifically noted on adjuvant product labeling. • Oil adjuvants must contain at least 80% high quality, petroleum (mineral) or modified vegetable seed oil with at least 15% surfactant emulsifiers. Nonionic Surfactant (NIS) • Apply at 0.25% v/v (1 qt per 100 gal spray solution). • Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance (HLB) greater than 12. Ammonium Nitrogen Fertilizer In addition to a spray adjuvant, an ammonium nitrogen fertilizer may be used. • Use 2 qt/acre of a high-quality urea ammonium nitrate (UAN) such as 28%N or 32%N, or 2 Ib/acre of a spray-grade ammonium sulfate (AMS).

When using liquid fertilizer as the carrier, always dissolve DPX-121 in clean water before adding fertilizer solutions. Add the dissolved DPX-121 solution to the final complete liquid fertilizer mixture - do not add DPX-121 during the fertilizer mixing process. Always use good agitation while adding the dissolved DPX-121 solution to liquid fertilizers and maintain good agitation until sprayed. When using liquid fertilizer as the carrier, conduct a compatibility test with all components prior to mixing. Do not use with spray additives or liquid fertilizer carriers that alter the pH of the spray solution below pH 5.0 or above pH 9.0 as rapid product degradation can occur. Spray solutions of pH 6.0 -8.0 allow for optimum stability of DPX-121. Water Carrier Instructions 1. Fill the tank 1/3 to 1/2 full of clean water. c c c c c c o 2. While agitating, add the required amount of DPX-121. tccc«-i. c 3. Continue agitation until the DPX-121 is fully dissolved, at least 5 minutes. When the water temperature ir Adf E or less, it is important to allow agitation and mixing to occur for the full S minutes to ensure ttie^riodrjct is completely dissolved. i. c c c«.- c 4. Once the DPX-121 is fully dissolved, maintain agitation and continue filling tank with water.l!>;PXt121 sh'ouitf be thoroughly mixed and dissolved with clean water before adding any other material such as Wk'cer^conditionerS or other additives. c t c c L ^ 5. As the tank is filling, add tank mix partners (if desired) in the proper mixing order. 6. Maintain agitation throughout mixing and application. If the mixture is not continuously agitated, settling could'o^curi 'if settling occurs, thoroughly re-agitate before using. 7. At the end of the day, or for extended periods of time between DPX-121 applications, it is recommended to flush the boom hoses and lines of spray solution and recharge with clean water. This will aid in proper sprayer cleanout when concluding DPX-121 applications before moving on to spray other products /crops. 8. Apply DPX-121 spray mixture within 48 hours of mixing to avoid product degradation. c cIf the selected companion herbicide has a ground or surface water advisory, consider this advisory when using the companion herbicide. Tank Mix Compatibility Testing Perform ajar test prior to tank mixing to ensure compatibility of DuPont™ DPX-121 and other pesticides. Use a clear quart jar with lid and mix the tank mix ingredients in their relative proportions. Invert the jar containing the mixture several times and observe the mixture for approximately 1/2 hour. If the mixture balls-ups, forms flakes, sludge, gel, oily film or layers, or other precipitates, it is not compatible and the tank mix combination should not be used. Ground Application When DPX-121 is used alone, use a minimum of 15 gallons of water per acre (GPA) to ensure thorough coverage of the weeds and the best performance. When tank mixed with glyphosate, use a minimum of 5 to 10 GPA. For best performance, select nozzles and pressure that deliver MEDIUM spray droplets, as indicated, for example, by AS ABE Standard S572.1. Nozzles that deliver COARSE spray droplets may be used to reduce drift, provided spray volume is increased to maintain coverage on small weeds. For optimal product performance and minimal spray drift, adjust the spray boom to the lowest possible spray height recommended in manufacturers' specifications Aerial Application Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage at a minimum of 5 GPA. Do not apply during a temperature inversion, when winds are gusty, or when conditions favor poor coverage and/or offtarget spray movement. ROTATIONAL CROP GUIDELINES The following rotational intervals must be observed: UP TO 1.5 OZ/A MAXIMUM USE RATE Rotation Crop Interval (months) Com, field Anytime • Potatoes 1 STS Soybeans* 1 Cereals, Winter 3 Cereals, Spring 9 Com, pop, seed or sweet . 10 Flax . 10 Peas . 10 Sorghum 10 Snap beans, dry beans 10 Soybeans 10 Sunflower 10 Sugarbeets 18 Alfalfa 18 Canola 18 Crops Not Listed ; 18 * Sulfonylurea Tolerant Soybean SPRAYER PREPARATION/CLEANUP The spray equipment must be cleaned before DPX-121 is sprayed.

Empty the tank and drain the sump completely. c c 2. Spray the tank walls with clean water using a minimum volume of 10% of the tank volume. Circulate the water'through the lines, including all by-pass lines, for at least two minutes. Flush the boom well and empty the sprayer. Completely drain the sump. ' < c' c I 3. Repeat step 2. 4. Remove the nozzles and screens and the end caps of sprayer booms and clean separately in a bucket containing water. The rinsate solution may be applied back to the crop(s) listed on this label. Do not exceed the maximum labeled use rate. If cleaners are used, consult the cleaner label for rinsate disposal instructions. If no instructions are given, dispose of the rinsate on site or at an approved waste disposal facility. 7 Notes: 1. Always start with a clean spray tank, hoses, boom and nozzles. Ensure boom sections between end nozzles and the end of the boom are clean of deposits (it is recommended to remove end caps and visually inspect). If needed, thoroughly flush rinse water through the boom sections with the end caps removed to ensure booms are clean and free of any residue or deposits. 2. A steam-cleaning aerial spray tank is recommended to facilitate the removal of any caked deposits. 3. When DuPont™ DPX-121 is tank mixed with other pesticides, all cleanout procedures for each product should be examined and the most rigorous procedure should be followed. 4. Follow any pre-cleanout guidelines recommended on other product labels. SPRAY DRIFT MANAGEMENT The interaction of many equipment and weather-related factors determines the potential for spray drift. The applicator is responsible for considering all these factors when making application decisions. Avoiding spray drift is the responsibility of the applicator. IMPORTANCE OF DROPLET SIZE The most effective drift management strategy is to apply the largest droplets which are consistent with pest control objectives. The presence of sensitive species nearby, the environmental conditions, and pest pressure may affect how an applicator balances drift control and coverage. Applying larger droplets reduces drift potential, but will not prevent drift if applications are made improperly or under unfavorable environmental conditions. A droplet size classification system describes the range of droplet sizes produced by spray nozzles. The American Society of Agricultural and Biological Engineers (ASABE) provide a Standard that describes droplet size spectrum categories defined by a number of reference nozzles (fine, coarse, etc.). Droplet spectra resulting from the use of a specific nozzle may also be described in terms of volume mean diameter (VMD). Coarser droplet size spectra have larger VMD's and lower drift potential CONTROLLING DROPLET SIZE - GROUND APPLICATION • Nozzle Type - Select a nozzle type that is designed for the intended application. With most nozzle types, narrower spray angles produce larger droplets. The use of low-drift nozzles will reduce drift potential. • Pressure - The lowest spray pressures recommended for the nozzle produce the largest droplets. Higher pressure reduces droplet size and does not improve canopy penetration. When higher flow rates are needed, using a higher-capacity nozzle instead of increasing pressure results in the coarsest droplet spectrum. • Flow Rate/Orifice Size - Using the highest flow rate nozzles (largest orifice) that are consistent with pest control objectives reduces the potential for spray drift. Nozzles with higher rated flows produce coarser droplet spectra. CONTROLLING DROPLET SIZE - AIRCRAFT • Nozzle Type - Solid stream, or other low drift nozzles produce the coarsest droplet spectra. • Number of Nozzles - Using the minimum number of nozzles with the highest flow rate that provide uniform coverage will produce a coarser droplet spectrum • Nozzle Orientation - Orienting nozzles in a manner that minimizes the effects of air shear will produce the coarsest droplet spectra. For some nozzles such as solid stream, pointing the nozzles straight back parallel to the airstream will produce a coarser droplet spectrum than other orientations. • Pressure - Selecting the pressure that produces the coarsest droplet spectrum for a particular nozzle and airspeed reduces spray drift potential. For some nozzle types such as solid streams, lower pressures can produce finer droplet spectra and increase drift potential BOOM LENGTH (AIRCRAFT), AND APPLICATION HEIGHT , <, c c c c c c Boom Length (aircraft) - Using shorter booms decreases drift potential. Boom lengths are expressed as a percentage of an aircraft's wingspan or a helicopter's rotor blade diameter. Shorter boom length and proper positioriih£(c
