your state. Always read the entire label, including the Conditions of Sale and Limitation of Warranty and Liability. PRODUCT INFORMATION WC-DCB is formulated as water dispersible granule intended for use in a spray to control and suppression of many annual, biennials, and perennial broadleaf weeds, as well as woody brush and vines listed in the “Weed Control Information” section of this label. WC-DCB may be used for control of these weeds in asparagus, corn, cotton, conservation reserve programs, fallow cropland, grass grown for seed, hay, proso millet, pasture, rangeland, farmstead (noncropland), small grains, sorghum, sugarcane, and turf. MODE OF ACTION WC-DCB is readily absorbed by plants through shoot and root uptake, translocates throughout the plant's system, and accumulates in areas of active growth. WC-DCB interferes with the plant's growth hormones (auxins) resulting in death of many broadleaf weeds. RESTRICTIONS •DO NOTtreat irrigation ditches or water used for crop irrigation or domestic uses. •DO NOTapply this product through any type of irrigation system. •DO NOTapply this product in a way that will contact workers or other persons, either directly or through drift.

PRECAUTIONS WC-DCB 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 WC-DCB during their development

or growing stage. Stress. DO NOTapply to crops under stress due to lack of moisture, hail damage, flooding, herbicide injury, mechanical injury, insects, or widely fluctuating temperatures as injury may result. Rainfall or irrigation occurring within 4 hours after postemergence applications may reduce the effectiveness of WC-DCB. WEED RESISTANCE MANAGEMENT WC-DCB, which contains the active ingredient dicamba is a group 4 herbicide based on the mode of action classification system of the Weed Science Society of America. Although WC-DCB has a low probability of selecting for resistant weed biotypes. Tank mixes and rotation with herbicides possessing other modes of action are recommended to avoid weed resistance. The following directions apply to all uses of WC-DCB. Additional precautions and restrictions will be found in each specific use section. Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one or more herbicides is a best practice. A diversified weed management program may include the use of multiple herbicides with different sites of action and overlapping weed spectrum with or without tillage operations and/or other cultural practices. Research has demonstrated that using the labeled rate and directions for use is important to delay the selection for resistance. The continued effectiveness of this product depends on the successful implementation of a weed resistance management program. To aid in the prevention of developing weeds resistant to this product, users should: •Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes present. •Start with a clean field, using either a burndown herbicide application or tillage. •Control weeds early when they are relatively small (less than 4 inches). •Apply full rates of WC-DCB for the most difficult to control weed in the field at the specified time (correct weed size) to minimize weed escapes. •Scout fields after application to detect weed escapes or shifts in control of weed species. •Control weed escapes before they reproduce by seed or proliferate vegetatively. •Report any incidence of non-performance of this product against a particular weed to your FMC representative, local retailer, or county extension agent. •Contact your FMC representative, crop advisor, or extension agent to find out if suspected resistant weeds to these MOAs have been found in your region. DO NOT assume that each listed weed is being controlled by multiple sites of action. Products with multiple active ingredients 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 resistance is suspected, treat weed escapes with an herbicide having a site of action other than Group 4 and/or use nonchemical methods to remove escapes, as practical, with the goal of preventing further seed production. •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; and -Surviving plants mixed with controlled individuals of the same species. Additionally, users should follow as many of the following herbicide resistance management practices as is practical: •Use a broad-spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program. •Utilize sequential applications of herbicides with alternative sites of action. •Rotate the use of this product with non-Group 4 herbicides. •Avoid making more than two applications of WC-DCB and any other Group 4 herbicides within a single growing season unless mixed with an herbicide with a different site of action with an overlapping spectrum for the difficult- to-control weeds. •Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover crops and weed-free crop seeds, as part of an integrated weed control program. •Use good agronomic principles that enhance crop development and crop competitiveness. •Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds. •Manage weeds in and around fields, during and after harvest to reduce weed seed production. INTEGRATED PEST MANAGEMENT This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field scouting or other detection methods, correct target pest identification, population monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooperative extension

6

service, professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area. APPLICATION INFORMATION UNLESS OTHERWISE SPECIFIED UNDER THE INDIVIDUAL USE HEADINGS OF THIS LABEL, THE FOLLOWING DIRECTIONS APPLY TO ALL CROP AND NONCROP USES OF WC-DCB. REFER TO INDIVIDUAL USE SECTIONS FOR ADDITIONAL PRECAUTIONS, RESTRICTIONS, APPLICATION RATES AND TIMINGS. WC-DCB is a water dispersible formulation that can be applied using water or sprayable fluid fertilizer as the carrier. If a fluid fertilizer is to be used, a compatibility test (see COMPATIBILITY TEST) should be made prior to tank mixing. It is the pesticide user's responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and 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. Ground or aerial application equipment which will give good spray coverage of weed foliage should be used. Avoid disturbing (e.g. cultivating or mowing) treated areas for at least 7 days following application. Application Instructions WC-DCB can be applied to actively growing weeds as aerial, broadcast, band, or spot spray applications using water or sprayable fertilizer as a carrier. For WC-DCB application rates for control or suppression by weed type and growth stage see the Application Ratessection, table WC-DCB Application Rates for Control or Suppression by Weed Type and Growth Stage. For crop-specific application timing and other details, refer to Crop-specific Information. To avoid uneven spray coverage, WC-DCB must not be applied during periods of gusty wind or when wind is in excess of 15 mph. Avoid off- target movement. Use extreme care when applying WC-DCB to prevent injury to desirable plants and shrubs. DO NOTtreat areas where either possible downward movement into the soil or surface washing may cause contact of WC-DCB with the roots of desirable plants such as trees and shrubs. To avoid injury to desirable plants, equipment used to apply WC-DCB should be thoroughly cleaned (see PROCEDURE FOR CLEANING SPRAY EQUIPMENT) before reusing to apply any other chemicals. All crop uses of WC-DCB are intended for a normal growing interval between planting and harvest. No crop rotation restrictions exist if normal harvest of treated crop has occurred. If this interval is shortened, such as in cover crops that will be plowed under, DO NOTfollow up with the planting of a sensitive crop. Crops growing under stress conditions such as drought, poor fertility, or foliar damage due to hail, wind or insects, can exhibit various injury symptoms that may be more pronounced if herbicides are applied Consult your local or state authorities for possible application restrictions and advice concerning these and other special local use situations. Tank mix directions are for use only in states where the tank mix product and application site are registered. Cultivation: DO NOTcultivate within 7 days after applying WC-DCB.

1. Rates below 6 ounces per acre may provide control or suppression but should typically be applied with other herbicides tha are effective on the same species and biotype.
2. Species noted with footnote 2 in this table require tank mixes for adequate control.
3. DO NOTbroadcast apply more than 24 ounces per acre per application. Use the higher level of listed rate ranges when treating dense vegetative growth or perennial weeds with well established root growth.
4. Retreatment or tank mixtures may be necessary for best control. However, DO NOTexceed a total of 48 ounces of WC- DCB per acre per year. Additives To improve postemergence weed control, agriculturally approved surfactants, sprayable fertilizers (urea ammonium nitrate, or ammonium sulfate), or crop oil concentrate may be added, particularly in dry growing conditions. (Refer to the table in this section entitled “Additive Rate per Acre”) Nitrogen Source: Urea ammonium nitrate (UAN): Use 2 to 4 quarts of UAN (commonly referred to as 28%, 30%, or 32% nitrogen solution) per acre. DO NOTuse brass or aluminum nozzles when spraying UAN. Ammonium sulfate (AMS): AMS at 2.5 pounds per acre may be substituted for UAN. Use high-quality AMS (spray grade) to avoid plugging of nozzles. Other sources of nitrogen are not as effective as those mentioned. FMC Corporation does not recommend applying AMS, if applied in less than 10 gallons per acre because of potential problems with precipitation in reduced volumes. Use AMS only if it has been demonstrated to be successful in local experience. Nonionic Surfactants The standard label recommendation is 1 pint of an 80% active nonionic spray surfactant per 100 gallons of water. For certain weeds, a higher spray surfactant rate is recommended. Crop Oil Concentrate or Methylated Seed Oil A crop oil concentrate must contain either a petroleum or vegetable oil base and must meet all of the following criteria: be nonphytotoxic, contain only EPA exempt ingredients, provide good mixing quality in the jar test, and be successful in local experience. The exact composition of suitable products will vary; however, vegetable and petroleum oil concentrates should contain emulsifiers to provide good mixing quality. Highly refined vegetable oils have proven more satisfactory than unrefined vegetable oils. For additional information, see Compatibility Test for Mix Components. Adjuvants containing crop oil concentrates may be used in preplant, preemergence, and preharvest application, as well as in pastures and noncropland. DO NOTuse crop oil concentrate for postemergence in-crop applications unless specifically allowed in Crop-specific Information section of this label. Additive Rate per Acre Additive Rate per Acre Nonionic Surfactant 1 to 2 pints per 100 gallons AMS 2.5 pounds UAN Solution 2 to 4 quarts Crop Oil Concentrate 1 quart* Methylated Seed Oil 1 quart* *See manufacturer’s label for specific rate instructions. Compatibility Test for Mix Components 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 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.

8

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 NOTmix the ingredients in the same tank. MIXING INSTRUCTIONS

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 fully dissolved and the product is evenly mixed in the spray tank before continuing.
5. Water-dispersible products -(dry flowables, wettable powders, suspension concentrates, or suspo- emulsions).
6. Water-soluble products- (including, WC-DCB).
7. Emulsifiable concentrates- (including, oil concentrate when applicable).
8. Water-soluble additives- (including, AMS or UAN when applicable).

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 degradation of this herbicide in soil. If dry weather prevails, use cultivation to allow herbicide contact with moist soil. •Planting/replanting restrictions for WC-DCB applications of 17 oz/A (0.7438 lb. ae/A) or less.No rotational cropping restrictions apply at 120 days or more following application. Additionally, for annual crop uses in this label including corn, cotton, sorghum, and soybean, follow the preplant use directions in crop-specific Information. For barley, oat, wheat, and other grass seedlings, the interval between application and planting is 15 days per 6 oz/A (0.2625 lb. ae/A)applied east of the Mississippi River and 22 days per 6 oz/A (0.2625 lb. ae/A)west of the Mississippi River. •Planting/replanting restrictions for applications of more than 17 oz (0.7438 lb. ae/A) and up to 48 ounces of WC- DCB per acre.Corn, sorghum, cotton (east of the 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, may be planted if the interval from application to planting is 30 days per 12 oz/A (0.525 lb. ae/A)(east of the Mississippi River) and 45 days per 12 oz/A (0.525 lb. ae/A) west of the Mississippi River. For all other crops in areas with less than 30" of annual rainfall, the interval between application and planting is 180 days or more. •Dicamba Tolerant Cotton or Dicamba Tolerant Soybeans may be planted at any time following an application of WC-DCB CROP SPECIFIC INFORMATION ASPARAGUS Apply WC-DCB to emerged and actively growing weeds in 40 to 60 gallons of diluted spray per treated acre immediately after cutting the field, but at least 24 hours before the next cutting. Multiple applications may be made per growing season. If spray contacts emerged spears, crooking (twisting) of some spears may result. If such crooking occurs. discard affected spears. Rates: Apply 6 to 12 oz/A (0.2625 – 0.525 lb. ae/A) of WC-DCB to control annual sowthistle, black mustard, Canada and Russian thistle, and redroot pigweed (carelessweed). Apply 12 oz/A (0.525 lb. ae/A) of WC-DCB to control common chick-weed, field bindweed, nettleleaf goosefoot, and wild radish. Restrictions DO NOT exceed 12 oz/A (0.525 lb. ae/A) of WC-DCB in a single application. Multiple applications may be made per growing season. DO NOTexceed a total of 12 oz (0.525 lb. ae) of WC-DCB per treated acre, per crop year. DO NOTharvest prior to 24 hours after treatment. DO NOTuse in the Coachella Valley of California. Asparagus Tank Mixes Apply 6 to 12 oz/A (0.525 lb. ae/A) of WC-DCB with glyphosate or 2,4-D to improve control of Canada thistle and field bindweed. It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.

Between Crop Applications (Fallow) PREPLANT DIRECTIONS (POSTHARVEST, FALLOW. CROP STUBBLE, SET-ASIDE, Prevent Plant) FOR BROADLEAF WEED CONTROL WC-DCB can be applied either postharvest in the fall, spring, or summer during the fallow period or to crop stubble/set-aside acres. Apply WC-DCB as a broadcast or spot treatment to emerged and actively growing weeds after crop harvest (postharvest) and before a killing frost or in the fallow cropland or crop stubble the following spring or summer. See Crop Rotational Restrictions in the Restrictions and Limitations section for the required interval between application and planting to prevent crop injury. Rates and Timings Apply 3 to 24 oz/A (0.1313 – 1.05 lb. ae/A) of WC-DCB. Refer to the “Application Rates” section to determine use rates for specific targeted weed species. For best performance, apply WC-DCB when annual weeds are less than 6" 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 WC-DCB is applied when the majority of weeds have at least 4" to 6" of 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 WC-DCB. For seedling control, a follow-up program or other cultural practices could be instituted. For small grain in-crop uses of WC-DCB,refer to the small grain section for details. DO NOTexceed 24 oz/A (0.1313 – 1.05 lb. ae/A) of WC-DCB in a single application or season. Between Crop (Fallow) Tank Mixes In tank mixes with other suitable registered herbicides, apply 3 to 12 oz/A (0.1313 – 0.525 lb./ ae/A) of WC-DCB for control of annual weeds, or 12 to 24 oz/A (0.525 – 1.05 lb. ae/A) of WC-DCB for control of biennial and perennial weeds. It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. CORN (Field, Pop, Seed, and Silage) Direct contact of WC-DCB with corn seed must be avoided. If corn seeds are less than 1.5" below the soil surface, delay application until corn has emerged. Applications of WC-DCB to corn during periods of rapid growth may result in temporary leaning. Corn will usually become erect within 3 to 7 days. Cultivation should be delayed until after corn is growing normally to avoid breakage. Corn may be harvested or grazed for feed once the crop has reached the ensilage (milk) stage or later in maturity. DO NOTexceed 12 oz/A (0.525 lb. ae/A in a single application. Up to 2 applications of WC-DCB may be made during a growing season. Sequential applications must be separated by 2 weeks or more. DO NOTexceed a total of 17 oz/A (0.7438 lb. ae/A) of WC-DCB per crop year. DO NOTapply WC-DCB to seed corn or popcorn without first verifying with your local seed corn company (supplier) the selectivity of WC-DCB on your inbred line or variety of popcorn. This precaution will help avoid potential injury of sensitive varieties. Avoid using crop oil concentrates or methylated seed oil after crop emergence as crop injury may result. Use of crop oil concentrates or methylated seed oil are recommended only in dry conditions when corn is less than 5" tall and when applying WC-DCB alone or tank mixed with atrazine. Use of sprayable fluid fertilizer as the carrier is not recommended for applications of WC-DCB made after corn emergence. WC-DCB is not registered for use on sweet corn. Preplant and Preemergence Application in No-Tillage Corn Rates:Apply 12 oz/A (0.525 lb. ae/A) of WC-DCB on medium- or fine-textured soils containing 2.5% or greater organic matter. Use 6 oz/A (0.2625 lb. ae/A) of WC-DCB on coarse soils (sand, loamy sand, and sandy loam) or medium- and fine-textured soils with less than 2.5% organic matter. Timing:WC-DCB can be applied to emerged weeds before, during, or after planting a corn crop. When planting into a legume sod (e.g. alfalfa or clover), apply WC-DCB after 4" to 6" of regrowth has occurred.

12

Preemergence Application in Conventional or Reduced Tillage Corn Rates:Apply 12 oz (0.525 lb. ae) of WC-DCB per treated acre to medium- or fine-textured soils that contain 2.5% organic matter or more. DO NOTapply to coarse-textured soils (sand, loamy sand, or sandy loam) or any soil with less than 2.5% organic matter until after corn emergence (see Early Postemergence uses below). Timing:WC-DCB may be applied after planting and prior to corn emergence. Preemergence application of WC- DCB does not require mechanical incorporation to become active. A shallow mechanical incorporation is recommended if the application is not followed by adequate rainfall or sprinkler irrigation. Avoid tillage equipment (e.g. drags, harrows) that concentrates treated soil over seed furrow, as seed damage could result. Preemergence control of cocklebur, jimsonweed, and velvetleaf may be reduced if conditions such as low temperature or lack of soil moisture cause delayed or deep germination of weeds. Early Postemergence Application in all Tillage Systems Rates: Apply 12 oz (0.525 lb. ae) of WC-DCB per treated acre. Reduce the rate to 6 oz (0.2625 lb. ae) of WC-DCB per treated acre for corn grown on coarse-textured soils (sand, loamy sand, and sandy loam). Timing: Apply between corn emergence and the 5-leaf stage or 8" tall, whichever occurs first. Refer to Late Postemergence Application if the sixth true leaf is emerging from whorl or the corn is greater than 8" tall. Late Postemergence Application Rate: Apply 6 oz (0.2625 lb. ae) of WC-DCB per treated acre. Timing: Apply WC-DCB from 8" to 36" tall corn or 15 days before tassel emergence, whichever comes first. For best performance, apply when weeds are less than 3" tall. Apply directed spray when com leaves prevent proper spray coverage, sensitive crops are growing nearby, or tank mixing with 2,4-D. DO NOTapply WC-DCBwhen soybeans are growing nearby if any of these conditions exist: •corn is more than 24" tall •soybean are more than 10" tall •soybean have begun to bloom Corn Tank Mixes and Sequential Uses When using tank mix or sequential applications with WC-DCB, always follow the companion product label to determine specific use rates by soil types, weed species, and weed or crop growth stage. Apply WC-DCB prior to, in tank mix with, or after other suitable registered herbicides. Observe all instructions, crop restrictions, mixing directions, application precautions, replanting directions, rotational crop guidelines and other label information of each product when tank mixing with WC-DCB or sequential applications. It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. Physical incompatibility, reduced weed control, or crop injury may result from mixing WC-DCB with other pesticides, additives, or fertilizers. Consult your state cooperative extension service, professional consultants or other qualified authorities when using products in a tank mix with WC-DCB. See table entitled “Specific Guidelines for Tank Mixes or Sequential Use Programs”for additional limitations or restrictions that apply for tank mix or sequential use programs with these products. Specific Guidelines for Tank Mixes or Sequential Use Programs Tank Mix Partner Rate Per Acre Herbicides containing nicosulfuron or primisulfuron-methyl When tank mixing, applications immediately following extreme day or night temperature fluctuations or applications when daytime temperatures DO NOTexceed 50° F may result in decreased weed control or crop injury. Delay application until the temperatures warm and both weeds and crop resume normal growth. 2,4-D To provide maximum crop safety after corn emergence, use this tank mix only after corn is greater than 8" tall and when application can be made with drop pipes that direct spray beneath corn leaves and away from the whorl of the com. The maximum rate of 2,4-D in this tank mix is 0.125 pounds of acid equivalent per acre.

13

Herbicides containing dicamba or dicamba + atrazine Tank mixes with these products that contain dicamba must not exceed a total combined rate of 0.50 pounds of dicamba acid equivalent per acre (0.25 pound on coarse-textured soils or on any soil when corn is greater than 8" tall). Sequential applications of these products must be separated by a minimum of 2 weeks (unless the combined rate is less than 0.5 pounds of dicamba acid equivalent and corn is 8" tall or less) and must not exceed a combined total of 0.75 pounds dicamba acid equivalent per acre for in-crop use. COTTON Preplant Applications Apply up to 6 oz/A (0.2625 lb. ae) of WC-DCB per acre to control emerged broadleaf weeds prior to planting cotton in conventional or conservation tillage systems. For best performance, apply WC-DCB when weeds are in the 2 to 4 leaf stage and rosettes are less than 2" across. Following application of WC-DCB and a minimum accumulation of 1" of rainfall or overhead irrigation, a waiting interval of 21 days is required per 6 oz (0.2625 lb. ae) per acre or less. These intervals must be observed prior to planting cotton. Dicamba Tolerant (DT) Cotton may be planted any time after an application of WC-DCB DO NOT exceed 6 oz/A (0.2625 lb.ae/A). DO NOTapply preplant to cotton west of the Rockies. DO NOTmake WC-DCBpreplant applications to cotton in geographic areas with average annual rainfall less than 25". If applying a spring preplant treatment following application of a fall preplant (postharvest) treatment, then the combination of both treatments must not exceed 48 oz/A (2.1 lbs. ae/A). Cotton Tank Mixes For control of grasses or additional broadleaf weeds, WC-DCB may be tank mixed with suitable registered herbicide containing prometryn, paraquat, and glyphosate. It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. GRASS GROWN FOR SEED Apply 6 to 12 oz/A (0.2625 to 0.525 lb. ae/A) of WC-DCB per treated acre on seedling grass after the crop reaches the 3 to 5 leaf stage. Apply up to 24 oz/A (1.05 lbs. ae/A) of WC-DCB on established perennial grass. For best performance, apply WC-DCB when weeds are in the 2 to 4 leaf stage and rosettes are less than 2" across. Use the higher level of listed rate ranges when treating more mature weeds or dense vegetative growth. To suppress annual grasses such as brome (downy and ripgut), rattail fescue, and windgrass, apply up to 24 oz/A (1.05 lbs. ae/A) of WC-DCB per treated acre in the fall or late summer after harvest and burning of established grass seed crops. Applications should be made immediately following the first irrigation when the soil is moist and before weeds have more than 2 leaves. DO NOT exceed 24 oz/A (1.05 lb. ae/A) of WC-DCB in a single application. DO NOT exceed 48 oz/A (2.1 lb. ae/A) of WC-DCB per season. DO NOTapply WC-DCB after the grass seed crop begins to joint. Refer to the Pasture, Hay, Rangeland, and Farmstead section for grazing and feeding restrictions. Grass Seed Tank Mixes WC-DCB may be applied in tank mixes with suitable registered herbicides containing MCPA amine, 2,4-D amine or ester, clopyralid, clopyralid + 2, 4-D, tribenuron-methyl (e.g. Express® herbicide (with TotalSol® soluble granules) and dicamba. It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. Refer to the Pasture, Hay, Rangeland, and Farmstead section for grazing and feeding restrictions. PROSO MILLET For use only within Colorado, Nebraska, North Dakota, South Dakota, and Wyoming. WC-DCB combined with 2,4-D will provide control or suppression of the annual broadleaf weeds listed in the “Weed Control Information” section of this label.

14

Apply 3 oz/A (0.1313 lb. ae/A) of WC-DCB with 0.375 pounds ai/A of 2,4-D. Apply the tank mix of a suitable registered herbicide containing dicamba + 2.4-D as a broadcast or spot treatment to emerged and actively growing weeds and when prose millet is in the 2 to 5 leaf stage. Use directions for dicamba and 2,4-D products vary with manufacturers. Refer to a dicamba and 2,4-D product with labeling consistent with the crop stage timing for the dicamba containing herbicide. Some types of proso millet may be affected adversely by a tank mix of dicamba + 2,4- D. DO NOT exceed 3 oz/A (0.1313 lb. ae/A) per single application. DO NOT exceed 3 oz/A (0.1313 lb. ae/A) per season. DO NOTapply unless possible proso millet crop injury will be acceptable. Restrictions for proso millet that is grazed or cut for hay are indicated in Table 3.Timing Restrictions for Lactating Dairy Animals Following Treatment in Pasture, Hay, Rangeland, and Farmstead section of this label. PASTURE, HAY, RANGELAND, AND FARMSTEAD (NONCROPLAND) WC-DCB may be used on pasture, hay, rangeland, and farmstead (non-cropland) (including fencerows and non- irrigation ditchbanks) for control or suppression of broadleaf weed and brush species listed in the “Weed Control Information” section of this label. WC-DCB may also be applied to non-cropland areas to control broadleaf weeds in noxious weed control programs, districts, or areas including broadcast or spot treatment of roadsides and highways, utilities, railroad, and pipeline rights-of-way. Noxious weeds must be recognized at the state level, but programs may be administered at state, county, or other level. WC-DCB uses described in this section also pertain to small grains (forage sorghum, rye, sudangrass, barley, triticale, or wheat) grown for pasture use only. Some perennial weeds may be controlled with lower rates of either WC-DCB or WC-DCB plus 2,4-D (refer to the “Application Rates” section). It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. Rates and Timing Refer to the “Application Rates” section for rate selection based on targeted weed or brush species. Some weed species will require tank mixes for adequate control. DO NOTbroadcast apply more than 24 oz/A (1.05 lbs. ae/A) of WC-DCB in a single application. DO NOTbroadcast apply more than 24 oz/A (1.05 lbs. ae/A) of WC-DCB per season. Retreatments may be made as needed; however, DO NOTexceed a total of 24 oz/A (0.1.05 lb. ae/A) of WC-DCB per treated acre during a growing season. Crop-Specific Restrictions and Limitations DO NOTapply more than 12 oz/A (0.525 lb. ae/A) of WC-DCB per acre to cereal grains grown for pasture. DO NOT apply to cereal grains or pastures under seeded with desirable broadleaf crops Newly seeded areas may be severely injured if more than 12 oz/A (0.525 lb. ae/A) of WC-DCB is applied per acre. Established grass crops growing under stress can exhibit various injury symptoms that may be more pronounced if herbicides are applied. Bentgrass, carpetgrass, buffalo-grass, and St. Augustinegrass may be injured if more than 12 oz/A (0.525 lb. ae/A) of WC-DCB is applied per acre. Usually colonial bentgrasses are more tolerant than creeping types. Velvetgrasses are most easily injured. Treatments will kill or injure alfalfa, clovers, lespedeza, wild winter peas, vetch, and other legumes. There are no grazing restrictions for animals other than lactating dairy animals. Table 3 lists the timing restrictions for grazing or harvesting hay from treated fields. Table 3. Timing Restrictions for Lactating Dairy Animals Following Treatment WC-DCB Rate per Treated Acre Days Before Grazing Days Before Hay Harvest Up to 12 oz/A (0.525 lb. ae/A) 7 davs 37 days Up to 24 oz/A (1.05 lbs. ae/A) 21 days 51 days Up to 48 oz/A (2.1 lbs. ae/A) 40 days 70 days WC-DCB can be applied using water, oil in water emulsions including invert systems, or sprayable fluid fertilizer as a carrier (refer to the Compatibility Test for Mix Components).

15

To prepare oil in water emulsions, half-fill spray tank with water, then add the appropriate amount of emulsifier. With continuous agitation, slowly add the herbicide and then the oil (such as diesel oil or fuel oil) or a premix of oil plus additional emulsifier to spray tank. Complete filling of spray tank with water. Maintain vigorous agitation during spray operation to prevent oil and water from forming separate layers. WC-DCB may be applied broadcast using either ground or aerial application equipment. Aerial Application Spray Volume. Use 2 to 40 gallons of diluted spray per treated acre in a water-based carrier. Ground Application Spray Volume. Use 3 to 600 gallons of diluted spray per treated acre. The volume of spray applied will depend on the height, density, and type of weeds or brush being treated and on the type of equipment being used. Spot Treatments. WC-DCB may be applied to individual clumps or small areas of undesirable vegetation using handgun or similar types of application equipment. Apply diluted sprays to allow complete wetting (up to runoff) of foliage and stems. CUT SURFACE TREATMENTS WC-DCB may be applied as a cut surface treatment for control of unwanted trees and prevention of sprouts of cut trees. Rate:Mix 30 to 90 oz (1.3125 to 3.9375 lbs. ae) WC-DCB with 1-gallon water to create the application solution. Use the lower dilution rate when treating difficult-to-control species. For Frill or Girdle Treatments: Make a continuous cut or a series of overlapping cuts using an axe to girdle tree trunk. Spray or paint the cut surface with the solution. For Stump Treatments: Spray or paint freshly cut surface with the water mix. The area adjacent to the bark should be thoroughly wet. NOTE: For more rapid foliar effects, 2,4-D may be added to the solution. APPLICATIONS FOR CONTROL OF DORMANT MULTIFLORA ROSE WC-DCB can be applied when plants are dormant as a spot treatment to the soil or as a Lo-Oil basal bark treatment using an oil-water emulsion solution. Spot treatments. Spot treatment applications of WC-DCB should be applied directly to the soil as close as possible to the root crown but within 6" to 8" of the crown. On sloping terrain, apply WC-DCB to the uphill side of the crown. DO NOTapply when snow or water prevents applying WC-DCB directly to the soil. The use rate of WC-DCB depends on the canopy diameter of the multiflora rose. Examples:Use 0.18, 0.72, or 1.7 oz (0.0079, 0.0315, or 0.0744 lb. ae) of WC-DCB respectively, for 5, 10, or 15 feet canopy diameters. Lo-Oil basal bark treatments. For Lo-Oil basal bark treatments, apply WC-DCB to the basal stem region from the ground line to a height of 12" to 18". Spray until runoff, with special emphasis on covering the root crown. For best results, apply WC-DCB when plants are dormant. DO NOTapply after bud break or when plants are showing signs of active growth. DO NOTapply when snow or water prevents applying WC-DCB to the ground line. To prepare approximately 2 gallons of a Lo-Oil spray solution:

1. Combine 1.5 gallons of water, 1 ounce of emulsifier, 12 oz (0.525 lb. ae) of WC-DCB, and 2.5 pints of No. 2 diesel fuel.
2. Adjust the amounts of materials used proportionately to the amount of final spray solution desired. DO NOTexceed 8 gallons of spray solution mix applied per acre, per year. Pasture Tank Mixes WC-DCB may be applied in tank mixes with other suitable registered herbicides It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. CONSERVATION RESERVE PROGRAM (CRP) WC-DCB may be used on both newly seeded and established grasses grown in Conservation Reserve or federal Set-Aside Programs. Treatments of WC-DCB will injure or may kill alfalfa, clovers, lespedeza, wild winter peas, vetch, legumes, and other desirable broadleaf plants.

16

Newly Seeded Areas WC-DCB may be applied either preplant or postemergence to newly seeded grasses or small grains including barley, oats, rye, sudangrass, wheat, or other grain species grown as a cover crop. Postemergence applications may be made after seedling grasses exceed the 3-leaf stage. Rates of WC-DCB greater than12 ounces per treated acre may severely injure newly seeded grasses. Preplant applications may injure new seedlings if the interval between application and grass planting is less than 45 days per 12 oz (0.525 lb. ae) of WC-DCB applied per treated acre west of the Mississippi River or 20 days per 12 oz/A (0.525 lb. ae/A) applied east of the Mississippi River. Established Grass Stands Established grass stands are perennial grasses planted one or more seasons prior to treatment. Certain species (bentgrass. carpetgrass, smooth brome, buffalograss, or St. Augustine grass) may be injured when treated with more than 12 ounces of WC-DCB per treated acre. When applied at specified rates. WC-DCB will control many annual and biennial weeds and provide control or suppression of many perennial weeds. Rates and Timings:Apply 3 to 24 oz/A (0.1313 to 1.05 lb. ae/A) of WC-DCB. Refer tothe Application Information Section, Additive Rate per Acretable for rates of various additives.WC-DCB may be tank mixed or applied sequentially with other suitably registered products labeled for use in Conservation Reserve Programs DO NOT exceed 24 oz/A (1.05 lb. ae/A) of WC-DCB in a single application. Retreatments may be made as needed; however, DO NOTexceed a total of 48 oz (2.1 lb. ae/A) of WC-DCB per acre. CEREAL GRAINS Not under seeded to legumes (fall- and spring-seeded barley, oat, triticale and wheat) WC-DCB combinations with suitable registered tank mix partners will provide control or suppression of the annual broadleaf weeds listed in the “Weed Control Information” section of this label. For improved control of listed weeds, tank mix WC-DCB with one or more of suitable registered herbicides. WC-DCB used in a tank mix with other herbicides offers the best spectrum of weed control and herbicide tolerant or resistant weed management. Refer to the specific section crop for WC-DCB application rate and timing. For applications prior to weed emergence or when sulfonylurea-resistant weeds are present or suspected, tank mix a minimum of 2 oz (0.0875 lb. ae) of WC-DCB per treated acre with a non-sulfonylurea herbicide including 2,4-D or MCPA. Tank mixing WC-DCB with these products will offer more consistent control of sulfonylurea-resistant weeds. Additives: When tank mixing WC-DCB with suitable registered sulfonylurea use 1 to 4 pints of an agriculturally approved surfactant (containing at least 80% active ingredient) per 100 gallons of spray or not more than 0.25 to 0.5% by volume. Use the highest rate of surfactant when using the lower rate ranges of the tank mix or when treating more mature and difficult to control weeds or dense vegetative growth. It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture. Refer to the specific crop sections below for use rates. When treating difficult to control weeds such as kochia, wild buckwheat, cow cockle, prostrate knotweed, Russian thistle, and prickly lettuce or when dense vegetative growth occurs, use the 2 to 3 oz (0.0875 to 0.1313 lb. ae) WC-DCB per acre. Timings: Apply WC-DCB before, during, or after planting small grains. See specific small grain crop uses below for maximum crop stage. For best performance, apply WC-DCB when weeds are in the 2 to 3 leaf stage and rosettes are less than 2" across. Applying WC-DCB to small grains during periods of rapid growth may result in crop leaning. This condition is temporary and will not reduce crop yields. Applications to small grains may be made with aerial applications with 1 gallon of water or more per acre. Where dense foliage is present, 2 to 3 gallons of water per acre should be used. Restrictions for small grain areas that are grazed or cut for hay are indicated in Table 3 inPasture, Hay, Rangeland, and Farmstead section of this label. CEREAL GRAINS: Barley (fall- and spring-seeded) Early Season Applications Apply 1.5 to 3 oz/A (0.0656 to 0.1313 lb. ae/A) of WC-DCB to fall-seeded barley prior to the jointing stage. Apply 1.5 to 2 ounces of WC-DCB before spring-seeded barley exceeds the 4-leaf stage.

NOTE:For spring barley varieties that are seeded during the winter months or later, follow the rates and timings given for spring-seeded barley. DO NOTtank mix WC-DCB with 2,4-D in early season applications on spring-seeded barley. PREHARVEST APPLICATIONS WC-DCB can be used to control weeds that may interfere with harvest of fall- and spring- seeded barley. Apply 6 oz (0.2625 lb. ae) of WC-DCB per acre as a broadcast or spot treatment to annual broadleaf weeds when barley is in the hard dough stage and the green color is gone from the node (joints) of the stem. Best results will be obtained if application can be made when weeds are actively growing, but before weeds canopy. A waiting interval of 7 days is required before harvest. DO NOTuse preharvest-treated barley for seed unless a germination test is performed on the seed with an acceptable result of 95% germination or better. For control of additional broadleaf weeds or grasses, WC-DCB may be tank mixed with other herbicides, such as 2,4-D, that are labeled for preharvest uses in barley. DO NOTmake preharvest applications in California. Barley Tank Mixes

CROPS This product can be used on the following crops: Asparagus Conservation Reserve Program (CRP) Corn Cotton Fallow Systems (Between-crop Applications) Proso Millet Pastures Rangeland Farmstead Small Grains (Barley, Oat, Triticale, and Wheat) Sorghum Soybean Sugarcane Turf Procedure for Cleaning Spray Equipment The steps listed below are suggested for thorough cleaning of spray equipment following applications of WC-DCB or tank mixes of WC-DCB. Step 1: Clean application equipment thoroughly by using a strong detergent or commercial sprayer cleaner, according to the manufacturer's directions, and then triple rinsing the equipment before and after applying this product. Step 2: Hose down thoroughly the inside as well as outside surfaces of equipment while filling the spray tank half full of water. Flush by operating sprayer until the system is purged of the rinse water. Step 3: Fill tank with water while adding 1 quart of household ammonia for every 25 gallons of water. Operate the pump to circulate the ammonia solution through the sprayer system for 15 to 20 minutes and discharge a small amount of the ammonia solution through the boom and nozzles. Let the solution stand for several hours, preferably overnight. Flush the solution out of the spray tank through the boom. Step 4: Remove the nozzles and screens and flush the system with two full tanks of water. The steps listed below are suggested for thorough cleaning of spray equipment used to apply WC-DCB as a tank mix with wettable powders (WP) emulsifiable concentrates (EC), or other types of water-dispersible formulations. WC-DCB tank mixes with water-dispersible formulations require the use of a water/detergent rinse.

1. Complete Step 1 (Above).
2. Fill tank with water while adding 2 lbs of detergent for every 40 gallons of water. Operate the pump to circulate the detergent solution through the sprayer system for 5 to 10 minutes and discharge a small amount of the solution through the boom and nozzles. Let the solution stand for several hours. preferably overnight.
3. Flush the detergent solution out of the spray tank through the boom. Repeat step 1 and follow with Steps 2, 3, and 4 (Above). Directions to Avoid Herbicide Drift: Sensitive Crop Precautions: WC-DCB 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 WC-DCB during their development or growing stage. DO NOTmake applications when spray particles may be carried by air currents to areas where sensitive crops and plants are growing. DO NOTspray near sensitive plants if wind is gusty or in excess of 5 mph and moving in the direction of adjacent sensitive crops. Leave an adequate buffer zone between area to be treated and only sensitive plants. Coarse sprays are less likely to drift out of the target area than fine sprays. Use coarse sprays (volume median diameter of 400 microns or more) to avoid potential herbicide drift. Select nozzles that are designed to produce minimal amounts of fine spray particles (less than 200 microns). Examples of nozzles designed to produce coarse sprays via ground applications are Delavan® Raindrops, Spraying

22

Systems XR (excluding 110° tips) flat fans, Turbo Teejets®, Turbo Floodjets®, or large capacity flood nozzles such as D10, TK10, or greater capacity tips. Keep the spray pressure at or below 20 psi and the 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. DO NOTapply WC-DCB adjacent to sensitive crops when the temperature on the day of application is expected to exceed 85° F as drift is more likely to occur. Agriculturally approved drift-reducing additives may be used. Aerial Application and Equipment: DO NOTUSE AERIAL APPLICATION EQUIPMENT IF SPRAY PARTICLES CAN BE CARRIED BY WIND INTO AREAS WHERE SENSITIVE CROPS OR PLANTS ARE GROWING. Use coarse sprays:WC-DCB must not be applied during periods of gusty wind or when wind is in excess of 15 mph as uneven spray coverage may occur. Water Volume:Use 1 to 10 gallons of water per acre (2 to 20 gallons of diluted spray per treated acre for preharvest uses). Use the higher spray volume when treating dense or tall vegetation. Select nozzles designed to produce minimal amounts of fine spray particles. Make aerial applications at the lowest safe height to reduce exposing the spray to evaporation and wind. The applicator must follow the most restrictive use cautions to avoid drift hazards, including those found in this labeling, as well as state and local regulations and ordinances. DO NOTuse aerial equipment if spray particles can be carried by the wind into areas where sensitive crops or plants are growing or when temperature inversions exist. Ground Application and Equipment: Ground Application (Banding)-Bandwidth in inches X Broadcast RATE per treated acre = Band RATE per treated acre. Row width in inches -Bandwidth in inches X Broadcast VOLUME per treated acre = Band VOLUME per treated acre. Row width in inches Ground Application (Broadcast)-Water Volume Use 3 to 50 gallons of spray solution per broadcast acre for optimal performance. Use the higher spray volume when treating dense or tall vegetation. -Application Equipment Use coarse sprays. 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. WC-DCB must not be applied during periods of gusty wind or when wind is in excess of 15 mph as uneven spray coverage may occur. Ground Applications (Wipers) WC-DCB may be applied through wiper application equipment to control or suppress actively growing broadleaf weeds, brush, and vines. Use a solution containing 90 ounces WC-DCB per 1-gallon water. DO NOTcontact desirable vegetation with herbicide solution.
