It is generally non-selective and gives broad spectrum control of many annual weeds, perennial weeds, woody brush and trees. Time to Symptoms: This product moves through the plant from the point of foliage contact to and into the root system. Visible effects on most allDual weeds occur within 2 to 4 days, but on most perennial weeds may not occur for 7 days or more. Extremely cool or Cloudy weather following treatment may slow activity of this product and delay development of visual symptoms. Visible effects are a gradual wilting and yellowing of the plant which advances to complete browning of above-ground growth and deterioration of underground plant parts.' , Stage or Condition of Weeds: Weeds must be emerged at the time of application to be controlled by this product. Weeds germinating from seed after application will not be·controlled. Unemerged plants arising from unattached underground rhizomes or root stocks of perennials will not be affected by the herbicQ.e. and will continue to grow. ' Weeds under poor growing conditions such as drought stress, disease or insect damage, may 'absorb less herbicide resulting in reduced weed control. Reduced results may also occur when treating weeds heavily covered with dust. Reduced control may result when applications are made to annual or perennial weeds that have been mowed, grazed, or cut, and have not been allowed to regrow to the recommended stage for treatment. Refer to the annual, perennial, woody brush and trees rate tables for recommendations for specific weeds. Rainfastness: Heavy rainfall soon after application may wash this product off of the foliage and a repeat application may be required for adequate control. Master Label 524-531 Version: 22-August-2007 Page 70f30 . ..

( ( /)- Spray Coverage: For best results, spray coverage should be unifonn and complete. However, spraying herbicide solution to the point of runoff is wasteful and should be avoided. Biological Degradation: Degradation of this product is primarily a biological process carried out by soil microbes. Tank Mixing:· This product does not provide residual weed control. For subsequent residual weed control, follow a label-approved herbicide program. Read and carefully observe the cautionary statements and all other infonnation appearing on the labels of all herbicides used. Use according to the most restrictive label directions for each product in the mixture, including retreatment intervals, and preharvest intervals. Carefully follow the maximum annual treatment rate for 2,4-D when mixing with other 2,4-D containing products. When this label recommends a tank mixture with a generic active ingredient such as atrazine or dicamba, the user must ensure that the mixture product's label allows the specific application site. ,., Buyer and all users are responsible for all loss or damage in connection with the use or handling of mixtures of this product with herbicides or other materials that are not expressly recommended in this labeling. Mixing this product with herbicides or other materials not recommended on this label may result in reduced perfonnance. Annual Maximum Use Rate: Except as otherwise specified in a crop section of this label, the combined total of all treatments must not 8 quarts of this product per acre per year. [Optional Statement: This maximum rate is equivalent to 0.64 pounds of2,4-D acid equivalents per acre per year and 6 pounds of glyphosate acid equivalents per acre per year.] For noncrop uses, the combined total of all treatments must not exceed 10.6 quarts of this product per acre per year. [Optional Statement: This maximum rate is equivalent to 0.85 pounds of2,4-D acid equivalents per acre per year and 8 pounds of glyphosate acid equivalents per acre per year.] The maximum use rates stated throughout this product's labeling apply to this product combined with the use of all other herbicides containing 2,4-D, glyphosate or sulfosate as the active ingredient, whether applied as mixtures or separately. Calculate the application rates and ensure that the total use of this and other products do not exceed stated maximum use rates. 6.0 MIXING Reduced results may occur if water containing soil is used, such as visibly muddy water or water from ponds and ditches that is not clear. 6.1 Mixing with Water or Liquid Nitrogen Solutions· This product mixes readily with water. Mix spray solutions of this product as follows: Fill the mixing or spray tank with the required amount of water. Add the recommended amount of this product near the end of the filling process. Where nonionic surfactant is recommended, add this to the spray tank before completing the filling process. Mix well. Use caution to avoid siphoning back into the carrier source. Use approved anti-back-siphoning devices where required by state or local regulations. During mixing and application, foaming of the spray solution may occur. To prevent or minimize foam, avoid the use of mechanical agitators, tenninate by-pass and return lines at the bottom ofthe tank and, if needed, use an approved anti-foam or defoaming agent. NOTE: Before mixing this product or labeled tank mixtures of this product with liquid nitrogen solutions, the planned combination should be tested for compatibility. Use 10 to 60 gallons of nitrogen solution per acre. 6.2 Tank Mixing Procedure Master Label 524-531 Version: 22-August-2007 Page 8 of30

( ( /3 ? 31' Mix labeled tank mixtures of this product with water as follows:

1. Place a 20 to 35 mesh screen or wetting basket over filling port.
2. Through the screen, fill the spray tank one-half full with water and start agitation.
3. If a wettable powder is used, make a slurry with the water carrier, and add it SLOWLY through the screen into the tank. Continue agitation.
4. If a flowable formulation is used, premix one part flowable with one part water. Add diluted mixture SLOWLY through the screen into the tank. Continue agitation.
5. If an emulsifiable concentrate formulation is used, premix one part emulsifiable concentrate with two parts water. Add diluted mixture slowly through the screen into the tank. Continue agitation. 6~· Continue filling the spray tank with water and add the required amount ofthis product near the end of .the filling process.
6. Where nonionic surfactant is recommended, add this to the spray tank before completing the filling process.
7. Add individual formulations to the spray tank as follows: wettable powder, flowable, emulsifiable concentrate, drift control additive, water soluble liquid followed by surfactant. Maintain good agitation at all times until the contents of the tank are sprayed. If the spray mixture is allowed to settle, thorough agitation is required to resuspend the mixture before spraying is resumed. Keep by-pass line on or near the bottom of the tank to minimize foaming. Screen size in nozzle or line strainers should be no finer than 50 mesh. Always predetermine the compatibility of labeled tank mixtures of this product with water carrier by mixing small proportional quantities in advance. . Refer to the "Tank Mixing" section of "GENERAL INFORMA nON" for additional precautions. 6.3 Mixing for Hand-held Sprayers Prepare the desired volume of spray solution by mixing the amount of this product in water as shown in the following table: Spray Solution Desired Volume 1 Gal 25 Gal 100 Gal 112% 2/30z 1 pt 2 qt 2 tablespoons = I fluid ounce 1% 1-1/30z 1 qt 1 gal : ~'r Amount ofRT Master 11/2% 2% 5% 10% 20z 2-2/30z 6-1I20z 12-3/40z 1-112 qt 2 qt 5 qt 10 qt 1-112 gal 2 gal 5 gal io gal For use in knapsack sprayers, it is suggested that the recommended amount of this product be mixed with water in a larger container.

( ( 6.4 Nonionic Surfactants Nonionic surfactants which are labeled for use with herbicides may be used with this product and labeled tank mixtures. The use of surfactants as additives does not reduce the application rate of this product required to achieve weed control. When adding additional surfactant, use 0.5 percent concentration (2 quarts per 100 gallons of spray solution) of surfactant containing at least 70 percent active ingredient or a 1 percent concentration (4 quarts per 100 gallons of spray solution) for those containing less than}O percent active ingredient. Read and carefully observe cautionary statements and other information appearing on the surfactant label. NOTE: Use of herbicides at lower than label recommended rates will result in reduced performance. 6.5 Ammonium Sulfate Th« addition of 1 to 2 percent dry ammonium sulfate by weight or 8.5 to 17 pounds per 100 gallons of water may increase the performance ofthis product, particularly when tank mixed with certain residual herbicides on annual and perennial weeds. The equivalent rate of ammonium sulfate in a liquid formulation may also be used. Ensure that ammonium sulfate is completely dissolved in the spray tank before adding herbicides or surfactant. Thoroughly rinse the spray system with clean water after use to reduce corrosion. NOTE: The use of ammonium sulfate as an additive does not preclude the need for additional surfactant. Recommended rates for herbicides and surfactant should be maintained when adding ammonium sulfate . . 6.6 Colorants or Dyes Agriculturally-approved colorants or marking dyes may be added to this product. Colorants or dyes used in spray solutions of this product may reduce performance, especially at lower rates or higher dilutions. Use colorants or dyes according to the manufacturer's recommendations. 6.7 Drift Control Additives Drift control additives may be used with all equipment types, except wiper applicators and sponge bars.

I ( 16 r 3'f' (vegetative stage), ornamentals, sunflowers, tomatoes, beans, and other vegetables or tobacco. Small amounts of spray drift that may not be visible may injure susceptible broadleaf plants. Avoid direct application to any body of water. 7.1 Aerial Equipment DO NOT APPLY THIS PRODUCT USING AERIAL SPRAY EQUIPMENT EXCEPT UNDER CONDITIONS AS SPECIFIED WITHIN THIS LABEL. Use the recommended rates of this herbicide in 3 to 15 gallons of water per acre unless otherwise specified on this label. Aerial applications of this product should not exceed 1 quart per acre unless otherwise specified. Aerial applications of this product may be made in annual cropping conventional tillage systems, fallow and reduced tillage systems and preharvest applications. Refer to the individual use area sections of this label for recommended volumes and application rates. Ensure uniform application-- To avoid streaked, uneven or overlapped application, use appropriate marking devices. Equipment Maintenance: Thoroughly wash aircraft, especially landing gear, after each day of spraying to remove residues of this product accumulated during spraying or from spills. Prolonged exposure of this product to uncoated steel surfaces may result in corrosion and possible failure ofthe part. Landing gear are most susceptible. The maintenance of an organic coating (paint), which meets aerospace specification MIL-C-38413, may prevent corrosion." Swath Adjustment: When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the up and downwind edges of the field, the applicator must compensate for this displacement by adjusting the path of the aircraft upwind. Swath adjustment distance should increase, with increasing drift potential (higher wind, smaller droplets, etc.). Boom Length: The boom length must not exceed 75% of the wingspan or 90% of the rotor diameter. Application Height: Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a height greater than 10 feet above the crop canopy unless a greater height is required for aircraft safety. 7.2 Ground Broadcast Equipment Use the recommended rates of this product in 3 to 10 gallons of water per acre as a broadcast spray UnJess otherwise specified. As density of weeds increases, spray volume may be increased up to 40 gallons ~itliin the recommended range to ensure complete coverage. Select proper nozzles to avoid spraying a fine mist. For best results with ground application equipment, use flat fan nozzles. Check for even distribution of spray droplets. Do not apply with a nozzle height greater than 4 feet above the crop canopy. 7.3 Hand-Held and High-Volume Equipment For applications made on a spray-to-wet basis, spray coverage should be uniform and complete. However, spraying herbicide solution to the point of runoff is wasteful and should be avoided. Use coarse sprays only. 7.4 Selective Equipment Master Label 524-531 Version: 22-August-2007 Page 12 of30

( ( 17 This product may be applied through shielded applicators, hooded sprayers, wiper applicators or sponge bars after dilution and thorough mixing with water to listed weeds growing in any noncrop site specified on this label and only when specifically recommended in cropping systems. ' Shielded and hooded applicators A shielded or hooded applicator directs the herbicide solution onto weeds, while shielding desirable vegetation from the herbicide. Use nozzles that provide uniform coverage within the treated area. Keep shields on these sprayers adjusted to protect desirable vegetation. EXTREME CARE MUST BE EXERCISED TO AVOID CONTACT OF HERBICIDE WITH DESIRABLE VEGETATION. A hooded sprayer is a type of shielded applicator. The spray pattern is completely enclosed on the top and all 4 sides by a hood, thereby shielding the crop from the spray soiution. This equipment must be set up and operated in a manner that avoids bouncing or raising the hoods off the ground in any way. If the hoods are raised, spray particles may escape and come into contact with the crop, causing damage or destruction of the crop. Droplets, mist, foam or splatter of the herbicide solution may contact the crop and cause discoloration, stunting or destruction. The spray hoods must be operated on the ground or skimming across the ground. Tractor speed must be adjusted to avoid bouncing of the spray hoods. Avoid operation on rough or sloping ground where the spray hoods might be raised off the ground. To minimize potential for crop injury: • The spray hoods must be operated on the ground or skimming across the ground. • Leave at least an 8 inch untreated strip over the drill row. For example, if the crop row width is 38 inches, the maximum width of the spray hood should be 30 inches. • Maximum tractor speed: 5 mph. • Maximum wind speed: 10 mph. • Use low-drift nozzles. Wiper applicators and sponge bars A wiper or sponge applicator applies the herbicide solution directly onto weeds by rubbing the weed with an absorbent material containing the herbicide solution. Equipment must be designed, maintained and operated to prevent the herbicide solution from contac1:ing desirable vegetation. Operate this equipment at ground speeds no greater than 5 mph. Performance may be improved by reducing'speed in areas of heavy weed infestations to ensure adequate wiper saturation. Better 'results may be obtained if2 applications are made in opposite directions. Applications made above the crops should be made when the weeds are a minimum of 6 inches above the desirable vegetation. Better results may be obtained when more of the weed is exposed to the herbicide solution. Weeds not contacted by the herbicide solution will not be affected. This may occur in dense clumps, severe infestations or when the height of the weeds varies so that not all weeds are contacted. In these instances, repeat treatment may be necessary. Avoid leakage or dripping onto desirable vegetation. Adjust height of applicator to ensure adequate contact with weeds. Keep wiping surfaces clean. Be aware that, on sloping ground, the herbicide solution may migrate, causing dripping on the lower end and drying of the wicks on the upper end of a wiper applicator. Master Label 524-531 Version: 22-August-2007 Page 13000

( /e8' Wiper equipment can be ineffective in transferring herbicide to weeds that are wet atthe time of application. Mix only the amount of solution to be used during a I-day period, as reduced activity may result from use ofleftover solutions. Clean wiper parts immediately after using this product by thoroughly flushing with water. Because wiper solutions are already very concentrated, no additional surfactant is needed. 7.5 Injection Systems This product may be used in aerial or ground injection spray systems. It may be used as a liquid concentrate or diluted prior to injecting into the spray stream. Because compatibility of concentrated products has not be~n tested, mixture of this product with the concentrate of other products is not advised when using injection systems. 8.0 CROPS (Alphabetical) This section is organized alphabetically by crop category.

L PRECAUTIONS, RESTRICTIONS: Contact of this product in any manner to any vegetation to which treatment in not intended may cause damage. Such damage shall be the sole responsibility of the applicator. Make up to 2 treatments per year and observe a 21-day retreatment interval. Wiper Applications PRECAUTIONS, RESTRICTIONS: Contact of the herbicide solution with desirable vegetation may result in damage or destruction. Applicators should be adjusted so that the wiper contact point is at least two (2).inches above the desirable vegetation. Weeds should be a minimum of six (6) inches above the desirable vegetation. Better results may be obtained when more of the weed is exposed to the herbicide solution. Weeds not contacted by the herbicide solution will not be affected. This may occur in dense clumps, severe infestations, or when height of weeds varies so that not all weeds are contacted. In these instances, repeat treatments may be necessary. Better results may be obtained if 2 applications are made in opposite djrections. Spot Treatments USE INSTRUCTIONS: Use a 1-1.5 percent solution. Creating Rows in Annual Ryegrass USE INSTRUCTIONS: Use 16-32 fluid ounces of this product per acre mixed with water. Use the higher rate when the ryegrass is greater than 6 inches tall. Best results are obtained when applications are made before the ryegrass reaches 6 inches in height. Grass that is sprayed will be destroyed. PRECAUTIONS, RESTRICTIONS: Set nozzle heights to allow the establishment of the desired row spacing while preventing spray droplets, spray fines, or drift to contact the ryegrass plants not treated. Use of low pressure nozzles, or drop nozzles designed to target the application over a narrow band are recommended. Grower assumes all responsibility for crop losses from misapplication. 8.8 Pastures GRAZING RESTRICTIONS: Do not graze lactating dairy animals on treated areas within 7 days after application.

TYPES OF APPLICATIONS: Preplant, preemergence, pasture renovation, spot treatment, wiper application. Preplant, Preemergence and Pasture renovation USE INSTRUCTIONS: This product may be used to control perennial pasture species listed on this label prior to re-planting. PRECAUTIONS, RESTRICTIONS: Remove domestic livestock before application and wait 8 weeks after application before grazing or harvesting. Spot treatment and Wiper application Master Label 524-531 Version: 22-August-2007 Page 20 of30

" I USE INSTRUCTIONS: This product may be applied as a spot treatment or with wiper applicators in pastures. Applications may be made in the same area at 30-day intervals. PRECAUTIONS, RESTRICTIONS: For spot treatment and wiper applications, apply in areas where the movement of domestic livestock can be controlled. No more than one-tenth of any acre should be treated at one time. Remove domestic livestock before application and wait 14 days after application before grazing livestock or harvesting. 8.9 Rangelands TYPES OF APPLICATIONS: Postemergence USE INSTRUCTIONS: This product will control or suppress many annual weeds growing in perennial cool and warm season grass rangelands. Preventing viable seed production is key to the successful control and invasion of annual grassy weeds in rangelands. Follow-up applications in sequential years should eliminate most of the viable seeds. Grazing of treated areas should be delayed to encourage growth of desirable perennials. Allowing desirable perennials to flower and reseed in the treated area will encourage successful transition. PRECAUTIONS, RESTRICTIONS: Use of ammonium sulfate when spraying rangeland grasses with this product is not recommended. Do not make more than one application per year. Do not graze lactating dairy animals on treated areas within 7 days after application. Do not harvest grass cut for hay from treated areas for 30 days. Withdraw meat animals from treated forage at least 3 days before slaughter. Postemergence Apply 12-16 fluid ounces of this product to control or suppress many weeds, including downy brome, cheat grass, cereal rye and jointed goatgrass in rangelands. Apply when most mature brome plants are in early flower and before the plants including seedheads tum color. Allowing for secondary weed flushes to occur in the. spring following rain events further depletes the seed reserve, and encourages perennial grass conversion on weedy sites. Fall applications are possible, and recommended where spring moisture is usually limited and fall germination allows for good weed growth. Apply 16 fluid ounces when the medusahead has reached the 3 leaf stage. Delaying applications beyond this stage will result in reduced or unacceptable control. Fire may be useful in eliminating the thatch'l~yer produced by slow decaying culms prior to application. Allow new growth to occur before spraying after a burn. Repeat applications in subsequent years may be necessary to eliminate the'seedbank before reestablishing desirable perennial grasses in rnedusahead dominated rangelands. Slight discoloration of the desirable grasses may occur, but they will n:green and regrow under moist soil conditions as effects of this product wear off. 8.10 Soybeans TYPES OF APPLICATIONS: Preplant USE INSTRUCTIONS: This product may be applied before planting soybeans. Applications must be made 15 days prior to planting of the crop. Under cold soil conditions, it is recommended to delay planting so that further time is available for the 2,4-D to dissipate from the soil. Master Label 524-531 Version: 22-August-2007 Page 21 of30
