2 ENGINEERING CONTROL STATEMENTS When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for agricultural pesticides [4 0 CFR part 170.240 (d)(4-6)], the handler PPE requirements may be reduced or modified as specified in the WPS. Important: When reduced PPE is worn because a closed system is being used, handlers must be provided all PPE specified above for "Applicators and Other Handlers" and have s uch PPE immediately available for use in an emergency, including a spill or equipment breakdown. USER SAFETY RECOMMEDATIONS USERS SHOULD: • Wash thoroughly with soap and water after handling and before eating, drinking, chewing gum, using tobacco, or using the toilet. • Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. • Remove PPE immediately after handling this product. Wash the ou tside of gloves before removing. As soon as possible, wash thoroughly and change into clean clothing ENVIRONMENTAL HAZARDS Do not apply directly to water, or to areas where surface water is present, or to intertidal areas below the mean high water mark. Do not contaminate water when cleaning equipment or disposing of equipment washwaters or rinsate. Groundwater Advisory This product is known to leach through soil into groundwater un der certain conditions as a result of label use. This product may leach into groundwater if used in areas where soils are permeable, particularly where the water table is shallow. Surface Water Advisory This product may impact surface water quality due to runoff of rain water. This is especially true for poorly draining soils and soils with shallow ground water. This product is classified as having high potential for reaching surface water via runoff for several weeks or more after application. A level , well-maintained vegetative buffer strip between areas to which this product is applied and surface water features incl uding ponds, streams, and springs will reduce the potential loading of this product from runoff water and sedimen t. Runoff of this product will be greatly reduced by avoiding applications when rainfall or irrigation is expected to occur within 48 hours. Windblown Soil Particles Advisory This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion usually have a high silt and/or fine to very fine sand fractions and low org anic matter content. Other factors which can affects the movement of windblown soil include the intensity and direction of prevailing winds, vegetative cover, site slope, rainfall, and drainage patterns. Avoid applying this product if prevailing local conditions may be expected to result in off-site movement. Non-target Organism Advisory This product is toxic to plants and may adversely impact the fo rage and habitat of non-target organisms, including pollinators, in areas adjacent to the treated area. Protect the forage and habitat of non-target organisms by minimizing spray drift. For further guidance and instructions on how to minimize spray drift, refer to the Spray Drift Management section of this label.

3 PESTICIDE HANDLING • Calibrate sprayers only with clean water away from the well site. • Make scheduled checks of spray equipment. • Ensure that all operation employees accurately measure pesticides. • Mix only enough product for the job at hand. • Avoid over-filling of spray tank. • Dilute and agitate excess solution and apply at labeled rates or uses. • Avoid storage of pesticides near well sites. • When triple rinsing the pesticide container, be sure to add the rinsate to the spray mix.

CHLORMET™ herbicide, referred to below as CHLORMET herbicide, mu st be used only in accordance with directions on this label or as otherwise permitted by FIFRA. Always read the entire label, including the Limitation of Warranty and Liability. To the extent consistent with applicable law, FMC will not be r esponsible for losses or damages resulting from the use of this product in any manner not specifically directed by FMC. PRODUCT INFORMATION CHLORMET herbicide is a dry-flowable granule that controls weeds in wheat (including durum), barley, triticale, fallow and CRP grasses. CHLORMET herbicide is mixed in water or may be slurried in water then added directly into liquid nitrogen fertilizer solutions and applied as a uniform broadcast spray. A surfactant must be u sed in the spray mix unless otherwise specified on this label. CHLORMET herbicide is noncorrosive, nonflammable, nonvolatile, and does not freeze. CHLORMET herbicide controls weeds by both preemergence and postemergence activity. For best preemergence results, apply CHLORMET herbicide before weed seeds germinate. Use sprinkler irrigation or allow rainfall to move CHLORMET herbicide 2" to 3" deep into the soil profile. For best postemergence results, apply CHLORMET herbicide to young, actively growing weeds. The use rate depends upon the weed spectrum and size of weeds at the time of application. The degree and duration of control may depend on the following: • weed spectrum and infestation density • weed size at application • environmental conditions at and following treatment

4 ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY CHLORMET herbicide is absorbed through the roots and foliage of plants, rapidly inhibiting the growth of susceptible weeds. For preplant and preemergence weed control, rainfall is needed to move CHLORMET herbicide into the soil. Weeds will generally not emerge from preplant and preemergence application s. In some cases, susceptible weeds may germinate and emerge a few days after application, but growth then ceases and leaves become chlorotic three to five days after emergence. Death of leaf tissue and growing point will follow in some spec i e s , w h i l e o t h e r s w i l l r e m a i n g r e e n b u t s t u n t e d a n d noncompetitive. One to three weeks after postemergence application to weeds, le aves of susceptible plants appear chlorotic, and the growing point subsequently dies. In warm, moist conditions, the express ion of herbicide symptoms is accelerated; in cold, dry conditions, expression of herbicide symptoms is delayed. Death of leaf tissue will follow in some species, while others will remain green but stunted and noncompetitive. Postemergence weed control may be reduced if rainfall occurs within 6 hours after application. CHLORMET herbicide provides the best control of weeds in vigorou sly growing crops that shade competitive weeds. Weed control in areas of thin crop stand or seeding skips may not pr ovide satisfactory control. However, a crop canopy that is too dense at application can intercept spray and reduce weed control. The herbicidal action of CHLORMET herbicide may be less effectiv e on weeds stressed from adverse environmental conditions (including extreme temperatures or moisture, drought stress), abnormal soil conditions, or cultural practices that increase weed stress. In these cases, tank mix CHLORMET herbici de with other registered herbicides (including 2,4-D, or MCPA) to aid in control. 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 p recautionary statements of each product in the tank mixture. If the instructions on the tank mix partner label conflicts with t his CHLORMET herbicide label, do not use in a tank mixture with CHLORMET herbicide. RESTRICTIONS

• Do not apply, drain, or flush equipment on or near desirable trees or other plants, or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots.
• Do not use on lawns, walks, driveways, tennis courts, or similar areas.
• Do not apply to wheat, barley, or triticale undersown with legumes and grasses, as injury to the forages will result.
• Do not apply to frozen ground where surface runoff may result.
• Do not apply to snow-covered ground.
• Do not apply to irrigated land where tailwater will be used to irrigate other cropland.
• Do not make more than one application of CHLORMET herbicide or any othe r chlorsulfuron containing product per growing season.
• Do not use in Alamosa, Conejos, Costilla, Rio Grande, and Saguache counties of Colorado.
• Do not discharge excess material on the soil at a single spot in the field, grove, or mixing/loading station.
• Do not store pesticides near well sites.
• Do not apply CHLORMET herbicide preemergence on cereals if the seed ha s germinated and has started to emerge above the soil surface.
• Do not use CHLORMET herbicide preemergence on cereals that have been planted into dry soil (“dusted in”) or on very coarse, uneven seedbeds. x Do notuse lessthan0.2oz per acreof CHLORMET herbicide preplant, preemergence or postemergence CHLORMET herbicide Active Ingredient Equivalent Rate Oz/A Chlorsulfuron Lb. ai/A Metsulfuron-methyl Lb. ai/A 0.2 0.0078 0.0016
• For all applications with products containing these active ing redients do not exceed 0.0625 oz ai/A (0.0039 Lb. ai/A) of metsulfuron methyl and 0.37 oz ai/A (0.0231 Lb. ai/A) of chlorsulfuron in a year.

5 PRECAUTIONS Injury to or loss of adjacent sensitive crops and vegetation may result from failure to observe thefollowing:

• Take all necessary precautions to avoid all direct or indirect contact (including spray drift) with non-target plants or areas.
• Carefully observe all sprayer cleanup instructions both prior to and after using this product, as spray tank residue may damage crops other than wheat, barley, oats and DuPont™ ExpressSun® sunflowers. • Varieties of wheat (including durum), barley, oats and tritica le may differ in their response to various herbicides. Consult your state experiment station, university, or extension agent a s to crop sensitivity to any herbicide. If no information is available, limit the initial use to a small area. • Wherever CHLORMET herbicide is used on land previously treated with Glean® XP herbicide , Ally® XP herbicide , Ally® ExtraSG herbicide (with Totalsol® soluble granules), Amber® Custom-Pak™ herbicide or other longer residual herbicides with the same mode of action, read the rotational guidelines on both labels and follow the one with the longest interval stated for your situation before choosing to rotate to crops other than wheat or barley. • To reduce the potential for movement of treated soil due to wind erosion, do not apply to powdery, dry, or light sandy soils until they have been stabilized by rainfall, trashy mulch, reduced tillage or other cultural practices. Injury to adjacent crops may result when treated soil is blown onto land used to produce crops other than cereal grains. • For ground applications applied postemergence to weeds when dry , dusty field conditions exist, control of weeds in wheel track areas may be reduced. Add 2,4-D or MCPA to improve weed control under these conditions. • Temporary discoloration and/or crop injury may occur if CHLORME T herbicide is applied when the crop is stressed by severe weather conditions (including heavy rainfall, prolonged cold weather, or wide fluctuations in day/night temperatures), disease or insect damage, low fertility, applications to coarse soils, or when applied in combination with surfactant and high rates of liquid nitrogen fertilizer solutions. • Dry, dusty field conditions may result in reduced control in w heel track areas. WEED RESISTANCE MANAGEMENT CHLORMET herbicide, which contains the active ingredients chlor sulfuron and metsulfuron methyl is a group 2 herbicide based on the mode of action classification system of the Weed Science Society of America. 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 manageme nt 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 succ essful implementation of a weed resistance management program. To aid in the prevention of developing weeds resistant to this product, users must: • 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 ap plication or tillage. • Control weeds early when they are relatively small (less than 4 inches). • Apply full rates of CHLORMET herbicide, 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 weedspecies. • Control weed escapes before th ey reproduce by seed or proliferate vegetatively. • Report any incidence of non-performance of this product agains t a particular weed to your FMC representative, local retailer, or county extension agent. • Contact your FMC representative, crop advisor, or extension age nt 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 sp ectrum of weeds that are controlled. Some weeds may be controlled by only one of the active ingredient in this product. • If resistance is suspected, treat weed escapes with an herbici de having a site of action other than Group 2 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 h erbicide at the dose applied, especially if control is achieved on adjacent weeds;
• A spreading patch of non-controlled plants of a particular wee d species;and
• Surviving plants mixed with controlled individuals of the same species.

6 Additionally, users must 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 o f herbicides with alternative sites ofaction. • Rotate the use of this product with non-Group 2 herbicides. • Avoid making more than two applications of CHLORMET herbicide, and any other Group 2 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, including mech anical 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 an d crop competitiveness. • Thoroughly clean plant residues from equipment before leaving fields su spected to contain resistant weeds. • Manage weeds in and around fields, during and after harvest to reduce weed seedproduction. 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, populati on monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooper ative extension 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 Chlormet herbicide may be tank mixed with other suitable registered herbicides to control weeds listed as partially controlled, weeds resistant to Chlormet herbicide or weeds not listed under the "WEEDS CONTROLLED" sections of this label. TANK MIX INFORMATION CHLORMET herbicide can be tank mixed with other products registe red for preplant/preemergence use in wheat including products with the active ingredient glyphosate. Read and follow all label instructions on timing, precautions, and warnings for any companion products before using these tank mixtures. It is the pesticide user's responsibility to ensure that all products are registered for the intended use. Read and follow the appli cable restrictions and limitations and directions for use on al l 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. CEREALS (WHEAT, BARLEY, TRITICALE) PREPLANT AND PREEMERGENCE Restrictions: x Do not apply CHLORMET herbicide preplant or preemergence on durum or Wampum wheat, barley, or triticale. x Do not apply preemergence or preplant incorporated to late fall planti ngs when cold and/or dry weather can cause delayed seedling emergence and/or stress to seedling plants. Under these conditions, wait until crop has emerged and is showing good vigor before making a postemergence treatment. x Do not apply CHLORMET herbicide during the boot stage or early heading stage, as crop injury may result. Precautions: x Crop injury may result when preemergence or preplant incorporated applications of CHLORMET herbicide are made to wheat seeded less than 1" deep. x Crop injury may result if CHLORMET herbicide is used where an organophosphate insecticide has been applied or is intended for use as an in-furrow treatment.

8 POSTEMERGENCE CHLORMET herbicide can be tank mixed with other products registered for postemergence use in wheat and barley. CHLORMET herbicide must not be used within 60 days of crop emergence if an organophosphate insecticide was used as an in-furrow treatment, or crop injury may result. In areas where late fall or winter cold weather conditions are unpredictable and can be severe (including the Pacific Northwest and Northern plains), to avoid crop injury due to cold weather, do not make applications during the 1 to 4-leaf stage of wheat, barley, or triticale. The combined effects of herbicide stress plus cold weather stress can result in greater crop injury than either stress factor alone. APPLICATION INFORMATION CHLORMET herbicide Active Ingredient Equivalent Postemergence: Apply CHLORMET herbicide at 0.2 to 0.4 oz per acre to wheat or barley any time after the crop is in the 1-leaf stage, but before boot stage.

10 CRP APPLICATIONS CHLORMET herbicide is for control of broadleaf weeds in the following perennial native or improved grasses grown on land enrolled in the Conservation Reserve Program (CRP): Bentgrasses Orchardgrass Blue Grama Sheep fescue Bluestems: big, little, plains, sand, WW spar Sideoats grama Buffalo grass Switchgrass – blackwell Green sprangletop Tall fescue Indiangrass Wheatgrasses: bluebunch, crested, intermediate, pubescent, Siberian, slender, streambank, tall, thickspike, western Kleingrass Wildgrass: beardless, Russian Lovegrasses: atherstone, sane, weeping, wilman, Maximize potential for grass establishment by consulting with the Natural Resources Conservation Service (NRCS) or other local experts concerning planting techniques and other cultural practices. Because newly planted CRP grass stands do not sufficiently compete with weeds and because weed pressure in CRP fields is often severe, performance from CHLORMET herbicide may not always be satisfactory. An addi tional herbicide application or mowing may be needed. PREPLANT (PRIOR TO PLANTING) APPLICATION INFORMATION CHLORMET herbicide Active Ingredient Equivalent CHLORMET herbicide may be applied at 0.2 – 0.4 oz per acre to all labelled grasses except bentgrasses, kleingrass, orchardgrass, plains and WW Spar bluestems, Russian wildrye grass, and sheep fescue. The 0.4 oz rate must be used for preemergence applications where residual weed control is important.

• When used as directed, weeds are suppressed and/or controlled. Weed suppression is a visible reduction in weed competition (reduced population and/or vigor) as compared to an untreated area. Degr ee of suppression will vary with rate used, size of weeds, and environmental conditions following treatment. † See the Specific Weed Instructions section for more information regarding controlling and suppressing these weeds. ‡ Naturally occurring resistant biotypes of these weeds are known to occur. See Tank Mixtures, Specific Weed Instructions, and Weed Resistance sections of this label for additional information.

13 SPECIFIC WEED INSTRUCTIONS It is the pesticide user’s responsibility to ensure that all pr oducts 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 precautionar y statements of each product in the tank m ixture. If the instructions on the tank mix partner label conflict with this CHLORMET herbicide label, do not use in a tank mixture with CHLORMET herbicide. Annual bluegrass/annual ryegrass CHLORMET herbicide Preemergence Apply CHLORMET herbicide at 0.5 oz per acre preplant or after planting winter wheat but before wheat emerges. or Apply CHLORMET herbicide at 0.5 oz per acre preplant or after planting winter wheat but before wheat emerges followed by a sequential application of metribuzin in the fall once the wheat has reached the 4 to 5-leaf stage of growth and the annual grassy weeds are in the 1 to 3-leaf stage of growth.

14 Bromus species (cheat, downy brome, Japanese brome): Best suppression of these grasses is achieved by applications of CHLORMET herbicide with metribuzin either in tank mixtures or as seque ntial treatments. Additional information may be available in a metribuzin supplemental label for winter wheat, barley, and fallow. Allow for adequate rainfall (1/2 to 1") to move CHLORMET herbic ide and metribuzin into the weed root zone before weeds germinate and develop an established root system. Lack of adequate rainfall following application will result in reduced performance. To avoid the risk of cold weather-related crop injury and lack of performance, apply metribuzin before winter dormancy of the crop and grassy weeds. Excessive rainfall immediately after application may result in crop injury. Do not tank mix CHLORMET herbicide plus metribuzin with any other pesticide othe r than surfactants specified on either the CHLORMET herbicide or metribuzin labels. Apply only to metribuzin-approved varieties, see metribuzin label for listing of sensitive wheat and barley varieties. Preemergence/Sequential Applications Apply CHLORMET herbicide at 0.5 oz per acre preemergence after planting winter wheat but before wheat emerges. A sequential application of metribuzin may be applied at label rates in the fall once the wheat has reached the 4 to 5-leaf stage of growth and the a n n u a l g r a s s y w e e d s a r e i n t h e 1 t o 3 - l e a f s t a g e o f growth.

17 TANK MIXTURES CHLORMET herbicide may be tank mixed with other registered herbi cides, fungicides, insecticides, or liquid fertilizer. 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. If the instructions on the tank mix partner label conflict with this CH LORMET herbicide label, do not use in a tank mixture with CHLORMET herbicide. Since tank-mix partners can interfere with CHLORMET herbicide di spersion in the spray solution, it is advised that CHLORMET herbicide be slurried in a separate container before adding it to the tank mix. CHLORMET herbicide must be in suspension in the spray tank before adding companion prod ucts. With 2,4-D (amine or ester) or MCPA (amine or ester) CHLORMET herbicide can be used as a tank-mix treatment with 2,4- D or MCPA herbicides (ester formulations provide best results) after weeds have emerged. For best results, use 0.2 to 0.4 oz of CHLORMET herbicide per acre; add 2,4-D or MCPA herbicides to the tank at labeled rates. Surfactant may be added to the mixture at 0.5 to 1 qt per 100 gal of spray solution; however, adding surfacta nt may increase the potential for crop injury. Do not add a surfactant when CHLORMET herbicide plus 2,4-D or MCPA is applied with liquid fertilizer. CHLORMET herbicide Active Ingredient Equivalent Rate (Oz/A) Chlorsulfuron (Lb. ai/A) Metsulfuron- methyl (Lb. ai/A) 0.2 0.0078 0.0016 0.4 0.0156 0.0031 Apply CHLORMET herbicide plus MCPA after the 3 to 5-leaf stage but before boot stage. Apply CHLORMET herbicide plus 2,4-D after tillering but before boot stage (refer to the appropriate 2,4-D manufacturer’s label). Applying a tank mixture of CHLORMET herbicide, 2,4-D, or MCPA and liquid fertilizer when temperatures are below freezing or when the crop is stressed from cold weather just prior to winter dormancy can result in foliar burn and/or crop injury. With Bromoxynil CHLORMET herbicide may be tank mixed at labeled rates with bromo xynil containing herbicides registered for use on wheat, barley or triticale. With Dicamba CHLORMET herbicide may be tank mixed with products containing th e active ingredient dicamba (including Banvel herbicide) at labeled rates. Use higher rates when weed infestation is hea vy. Nonionic surfactant may be added to the mixture at 0.5 to 1 quart per 100 gal of spray solution (0.125 to 0.25% v/v); however, adding nonionic surfactant may increase the potential for crop injury. Tank mixes of CHLORMET herbicide plus dicamba may result in reduced control of some broadleaf weeds. With Diuron In areas where annual bluegrass, annual ryegrass, corn gromwell , green foxtail (pigeongrass) and wild buckwheat are the main wee d problems, apply Karmex DF herbicide at labeled rates plus 0.3 t o 0.4 oz per acre CHLORMET herbicide preemergence. For best results between 1/2" and 1" of rainfall is needed within 1 to 2 weeks after application. Follow all restrictions and use instructions on the diuron labels. For summer fallow (CO, KS, NE, NM, OK, SD, TX, WY), apply Karmex DF herbicide or Direx® 4L herbicide at label rates (both products contain the active ingredient diuron) to wheat stubble or fallow in a tank mix with CHLORMET herbicide at 0.2 to 0.3 ounce per acre. Add a Crop Oil Concentrate (COC) at 1 to 2 % v/v or a non-ionic surfactant (NIS) at 0.25 to 0.5 % v/v. Glyphosat e products plus AMS may also be added as needed. When using glyphosate products that contain a built-in adjuvant system, ad d a NIS at 0.25% v/v. Allow at least 90 days after application befo re planting winter wheat. Refer to the tank mix partners for rates and use instructions.

18 With Fluroxypyr CHLORMET herbicide may be tank mixed with fluroxypyr containing herbicides for improved control of Kochia (2-4" tall) and other broadleaf weeds at labeled rates. 2,4- D and MCP herbicides may be tank mixed with CHLORMET herbicide plus fluroxypyr. With Other Broadleaf Control Products For improved control of broadleaf weeds, CHLORMET herbicide can be tank mixed with other herbicides registered on cereals including " WideMatch® herbicide, Aim® EC herbicide, Stinger® Herbicide,o r Curtail® Herbicide. With Grass Control Products For improved control of grass weeds, CHLORMET herbicide can be t ankmixed with other grass control herbicides registered on cereals including Axial® XL herbicide, Discover® NG herbicide, Everest® 3.0 herbi cide or PowerFlex® herbicide. Antagonism generally does not occur. However, FMC advises that yo u first consult your state experiment station, university, or extension agent, Agricultural dealer, or FMC representative as to the potential for antagonism before using the mixture. If no information is available, limit the initial use of CHLORMET herbicide and the grass product to a small area. With Insecticides CHLORMET herbicide may be tank mixed with insecticides registere d for use on wheat, barley, and fallow. However, under certain conditions (drought or cold stress while crop is in the 2- to 4-leaf stage), tank mixtures or sequential treatments of CHLORMET herbicide and organophosphate insecticide s may produce temporary crop yellowing or, in severe cases, crop injury. The potential for crop injury is gre atest when there are wide fluctuations in day/night temperatures just prior to or soon after treatment. Read and follow directions on companion product labels and limit first use to a small area. If no symptoms of crop injury appear, larger acreage can be treated. Restrictions: x Do not apply CHLORMET herbicide within 60 days of crop emergence where an organophosphate insecticide has been applied as an in-furrow treatment, as crop injury may result. x Do not use CHLORMET herbicide plus malathion, as crop injury may result. x In the Pacific Northwest, do not use CHLORMET herbicide with products containing the active ingredient chlorpyrifos as crop injury may result. With Fungicides CHLORMET herbicide may be tank mixed with other fungicides whenever the proper timing for herbicide and fungicide treatments coincide. With Liquid Nitrogen Fertilizer Solution Liquid nitrogen fertilizer solut ions may be used as a carrier i n place of water. Run a tank mix compatibility test before mixing CHLORMET herbicide in fertilizer solution. If 2,4-D or MC PA is included with CHLORMET herbicide and fertilizer mixture, ester formulations tend to be more compatible (See manufacturer’s label). If using low rates of liquid nitrogen fertilizer in the spray s olution (less than 50% of the spray solution volume), the addition of surfactant is necessary. When using high rates of l iquid nitrogen fertilizer in the spray solution, adding surfactant increases the risk of crop injury. Consult local specifications for details on surfactant addition. Restrictions: x DO NOT add surfactant when using CHLORMET herbicide in tank mix with 2, 4-D ester or MCPA ester and liquid nitrogen fertilizer solutions. x DO NOT use with liquid fertilizer solutions with a pH less than 3.0. x DO NOT use low rates of liquid fertilizer solution as a substitute for surfactant. GRAZING There are no grazing restrictions on CHLORMET herbicide. CROP ROTATION Before using CHLORMET herbicide, carefully consider your crop rotationplans and options. For rotational flexibility,do not treat all of your wheat, barley, or fallow acres at the same time.

19 MINIMUM ROTATION INTERVALS Minimum rotation intervals* are determined by the rate of breakdown of CHLORMET herbicide applied. CHLORMET herbicide breakdown in the soil is affected by soil pH, soil temperature, soil microorganisms, and soil moisture. Low soil pH, high soil temperature, and high soil moisture increase CHLORMET herbicide breakdown in soil, while high soil pH, low soil temperature, and low soil moisture slow CHLORMET herbicide brea kdown. Of these three factors, only soil pH remains relatively constan t. Soil temperature, and to a greater extent, soil moisture, can vary significantly from year to year and from area to area. For this reason, soil temperatures and soil moisture need to be monitored regularly when cons idering rotating to other crops.

• The minimum rotation interval represents the period of time from the last CHLORMET herbicide application to the anticipated date of the next planting. SOIL pH LIMITATIONS CHLORMET herbicide may not be used on fields having a soil pH a bove 7.9, as extended soil residual activity could extend crop rotation intervals beyond those specified in the ro tation table, and under certain conditions, could injure wheat or barley. In addition, other crops planted in high-pH so ils can be extremely sensitive to low concentrations of CHLORMET herbicide. CHLORMET herbicide may not be used on soils with a pH below 5.0 , as additional crop stress from low pH and aluminum toxicity may result in crop injury. Checking Soil pH Before using CHLORMET herbicide, determine the soil pH of the field. To obtain a representative pH value, take several samples from different areas of the field between 0" and 4" dee p and analyze them separately. Consult local extension publications for additional information on advised soil sampling procedures. BIOASSAY A field bioassay must be completed before rotating to any crop not listed (See the Rotation Intervals table), or if the soil pH is not in the specified range, or if the use rate applied is not specified in the table, or if the minimum cumulative precipitation has not occurred since application. To conduct a field bioassay, grow test strips of the crop or crops you plan to grow the following year in fields previously treated with CHLORMET herbicide. Crop response to the bioassay will indicate whether or not to rotate to the crop(s) grown in the test strips.

• In Idaho, Oregon & Washington for peas and lentils, a field bioassay is required if soil pH is above 6.5 **Under certain conditions (including drought, prolonged cold weather, pH variability in the fields) temporary discoloration and/or crop injury may occur to sulfonylurea tolerant (STS®) soybeans planted after CHLORMET herbicide applications. ***Where a CATASTROPHIC CROP LOSS has occurred after a CHLORMET herbicide application due to a natural disaster (including freezing weather, hail damage, insect damage, disease damage), grain sorghum can be planted at 4 months where the soil pH is 7.3 to 7.5 or sulfonylurea tolerant (STS®) soybeans where the soil pH is 7.5 to 7.9. These crops will have some level of temporary discoloration and/or crop injury if planted at this reduced interval after CHLORMET herbicide application. This potential damage and yield loss is accepted by the grower due to the critical need to get a crop planted after this emergency. Growers not willing to accept this level of potential early season crop injury and yield loss must follow the standard rotational guidelines in the table above. In some cases, this injury may be severe and may affect the crop growth, development, and yield. The severity of the injury increases with higher pH levels, higher applied CHLORMET herbicide rate, drier soil conditions after CHLORMET herbicide application and prior to planting the rotational crop, and the shorter the rotational interval. †These intervals may also be used for irrigated land. These intervals do not apply to crops grown for seed. ‡Rotation intervals are based on normal precipitation/irrigation amounts. If in a water deficit including a drought, extend rotation intervals until cumulative rainfall/irrigation reaches the normal range.

APPLICATION INFORMATION PRODUCT MEASUREMENT CHLORMET herbicide is measured using the CHLORMET herbicide volumetric measuring cylinder. The degree of accuracy of this cylinder varies by ± 7.5%. For more precise measurement, use scales calibrated in ounces. MIXING INSTRUCTIONS

1. Fill the tank 1/4 to 1/3 full of water (If using liquid nitro gen fertilizer solution in place of water, see Tank Mixtures se ctions for additional details).
2. While agitating, add the required amount of CHLORMET herbicide.
3. Continue agitation until the CHLORMET herbicide is fully dispersed, at least 5minutes.
4. Once the CHLORMET herbicide is fully dispersed, maintain agita tion and continue filling tank with water. CHLORMET herbicide needs to be thoroughly mixed with water before adding any other material.
5. As the tank is filling, add tank mix partners (if desired) th en add the necessary volume of nonionic surfactant. Always add surfactant last.
6. If the mixture is not continuously agitated, settling will occur. If settling occurs, thoroughly re-agitate beforeusing.
7. Apply CHLORMET herbicide spray mixture within 24 hours of mixing to avoid product degradation.
8. If CHLORMET herbicide and a tank mix partner are to be applied in multiple loads, pre-slurry the CHLORMET herbicide in clean water prior to adding to the tank. This will prevent the tank mix partner from interfering with the dissolution of the CHLORMET herbicide. Do not use CHLORMET herbicide with spray additives that reduce the pH of the spray solution to below 3.0. APPLICATION METHOD Ground Application To obtain optimum spray distribution and thorough coverage, use flat-fan or low-volume flood nozzles. When using flat-fan nozzles, use a spray volume of at least 3 GPA. When usingflood nozzles on 30" spacings, use at least 10 GPA, flood nozzles no larger than TK10 (or the equivalent), and a pressure of at least 30 psi. For 40" nozzle spacings, use at least 13 GPA; for 60" spacings, use at least 20 GPA. It is essential to overlap the nozzles100% for all spacings. With “Raindrop” RA nozzles,do notuse less than 20 GPA and overlap nozzles 100%. Use screens that are 50-meshor larger. Aerial Application Use nozzle types and arrangements that provide optimum spraydistribution and maximum coverage at 1 to 5 GPA. Use at least 3 GPAin Idaho, Oregon and Washington. When applying CHLORMET herbicide by air in areas near sensitive crops, use solid-stream nozzles oriented straight back. Chemigation Do not apply CHLORMET herbicide through any type of irrigation system. Before Spraying CHLORMET herbicide Spray equipment must be cleaned before CHLORMET herbicide is sprayed. Follow the cleanup procedures specified on the labels of previously applied products. If no directions are provided, follow the 6 steps outlined below. At the End of the Day

25 When multiple loads of CHLORMET herbicide are applied, it is adv ised that at the end of each day of spraying, the interior of the tank be rinsed with fresh water and then partially filled, and the boom and hoses be flushed. This will prevent the buildup of dried pesticide deposits from accumulating in the application equipment. After Spraying CHLORMET herbicide and before Spraying Crops Other than Wheat Barley, Triticale, Fallow, or CRP To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediately following applications ofCHLORMET herbicideasfollows:

1. Drain tank; thoroughly rinse spray tanks, boom, and hoses with clean water. Loosen and physically remove any visible deposits.
2. Fill the tank with clean water and 1 gal of household ammonia * (contains at least 3% active ingredient) for every 100 gal of water. Flush the hoses, boom, and nozzles with the cleaning solution. Then add more water to completely fill the tank. Circulate the cleaning solution through the tank and hoses for at least 15 min. Flush the hoses, boom, and nozzles again with the cleaning solution, and then drain the tank.
3. Remove the nozzles and screens and clean separately in a bucket containing ammonia* and water.
4. Repeat step 2.
5. Rinse the tank, boom, and hoses with clean water.
6. If only ammonia is used as a cleaner, the rinsate solution ma y be applied back to the crop(s) advised on this label. Do not exceed the maximum labeled use rate. If other cleaners are used , consult the cleaner label for rinsate disposal instructions. I f no instructions are given, dispose of the rinsate on site or at an approved waste disposal facility.

• Equivalent amounts of an alternate-strength ammonia solution or a cleaner which dissolves and removes sulfonylurea herbicide residues can be used in the cleanout procedure. Carefully read and follow the individual cleaner instructions. Notes:

1. Caution: Do not use chlorine bleach with ammonia, as dangerous gases will form.Do not clean equipment in an enclosed area.
2. Steam-cleaning aerial spray tanks is advised prior to performi ng the above cleanout procedure to facilitate the removal of an y caked deposits.
3. When CHLORMET herbicide is tank mixed with other pesticides, al l required cleanout procedures need to be examined and the most rigorous procedure needs to be followed.
4. In addition to this cleanout procedure, all preapplication cl eanout guidelines on subsequently applied products need to be followed as per the individual labels.
5. Where routine spraying practices include shared equipment fre quently being switched between applications of CHLORMET herbicide and applications of other pesticides to CHLORMET herbi cide-sensitive crops during the same spray season, it is advised that a sprayer be dedicated to CHLORMET herbicide to further reduce the chance of crop injury.

26 MANDATORY SPRAY DRIFT MANAGEMENT Ground Boom Applications: • Apply with the nozzle height advised by the manufacturer, but n o more than 3 feet above the ground or crop canopy. • For applications prior to the emergence of crops and target we eds, applicators are required to use a Coarse or coarser droplet size (ASABE S572.1). • For all other applications, applicators are required to use a Medium or coarser droplet size (ASABES572.1). • Do not apply when wind speeds exceed 10 miles per hour at the application site. • Do not apply during temperature inversions. Aerial Applications: • Do not release spray at a height greater than 10 feet above the vegetative canopy, unless a greater application height is necessary for pilot safety. • For applications prior to the emergence of crops and target we eds, applicators are required to use a Coarse or coarser droplet size (ASABE S572.1). • For all other applications, app licators are required to use a Medium or coarser droplet size (ASABES572.1). • The boom length must not exceed 65% of the wingspan for airplan es or 75% of the rotor blade diameter for helicopters. • Applicators must use one-half swath displacement upwind at the downwind edge of the field. • Nozzles must be oriented so the spray is directed toward the back of the aircraft. • Do not apply when wind speeds exceed 10 miles per hour at the application site. • Do not apply during temperature inversions. Boom-less Ground Applications: • Applicators are required to use a Medium or coarser droplet size (ASABE S572.1) for all applications. • Do not apply when wind speeds exceed 10 miles per hour at the application site. • Do not apply during temperature inversions. SPRAY DRIFT MANAGEMENT ADVISORIES THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT . BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITION S. IMPORTANCE OF DROPLET SIZE An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest control. While applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under unfavorable environmental conditions. Controlling Droplet Size – Ground Boom • Volume - Increasing the spray volume so that larger droplets ar e produced will reduce spray drift. Use the highest practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher flow rate. • Pressure - Use the lowest spray pressure advised for the nozzle to produce the target spray volume and droplet size. • Spray Nozzle - Use a spray nozzle that is designed for the inten ded application. Consider using nozzles designed to reduce drift. Controlling Droplet Size – Aircraft • Adjust Nozzles - Follow nozzle manufacturer’s directions for setting up nozzles. Generally, to reduce fine droplets, nozzles must be oriented parallel with the airflow in flight. BOOM HEIGHT – Ground Boom Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. For ground equipment, the boom must remain level with the crop and have minimal bounce. RELEASE HEIGHT - Aircraft Higher release heights increase the potential for spray drift. When applying aerially to crops, do not release spray at a height greater than 10 ft above the crop canopy, unless a greater application height is necessary for pilot safety.

27 SHIELDED SPRAYERS Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that the shields are not interfering with the uniform deposition of the spray on the target area. TEMPERATURE AND HUMIDITY When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation. TEMPERATURE INVERSIONS Drift potential is high during a temperature inversion. Tempera ture inversions are characterized by increasing temperature wit h altitude and are common on nights with limited cloud cover and light to no wind. The presence of an inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke generator. 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. Avoid applications during temperature inversions. WIND Drift potential generally increases with wind speed. AVOID APPL ICATIONS DURING GUSTY WIND CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray drift. HANDHELD TECHNOLOGY APPLICATIONS: • Take precautions to minimize spray drift. BOOM-LESS GROUND APPLICATIONS: Setting nozzles at the lowest effective height will help to reduce the potential for spray drift. DRIFT CONTROL ADDITIVES Using product compatible drift control additives can reduce drift potential. When a drift control additive is used, read and carefully observe cautionary statements and all other information on the additive’s label.
