ENVIRONMENTAL HAZARDS

This pesticide is toxic to fish. Drift or runoff from treated areas may be hazardous to aquatic organisms and non-target plants. 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 disposing of equipment washwater or rinsate.

Non-Target Organism Advisory This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, including pollinators, in areas adjacent to the treated site. Protect the forage and habitat of non-target organisms by following label directions intended to minimize spray drift.

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 after application. A level, well-maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, streams, and springs will reduce the potential loading of thiencarbazone-methyl from runoff water and sediment. Runoff of this product will be reduced by avoiding applications when rainfall or irrigation is expected to occur within 48 hours.

Ground Water Advisory This product has properties and characteristics associated with chemicals detected in ground water. This chemical may leach into ground water if used in areas where soils are permeable, particularly where the water table is shallow.

Endangered Species Advisory/Protection Requirements This product may have effects on federally listed threatened or endangered species or their critical habitat in some locations. When using this product, you must follow the measures contained in the Endangered Species Protection Bulletin for the county or parish in which you are applying the pesticide. To determine whether your county or parish has a Bulletin, and to obtain that Bulletin, consult http://www.epa.gov/espp/, or call 1-800-447-3813 no more than 6 months before using this product. Applicators must use Bulletins that are in effect in the month in which the pesticide will be applied. New Bulletins will generally be available from the above sources 6 months prior to their effective dates.

SPRAY DRIFT MANAGEMENT

MANDATORY SPRAY DRIFT

Aerial Applications: • Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a greater application height is necessary for pilot safety. • Applicators are required to use a medium or coarser droplet size (ASABE S572) for all applications. • If the windspeed is 10 miles per hour or less, applicators must use ½ swath displacement upwind at the downwind edge of the field. When the windspeed is between 11-15 miles per hour, applicators must use ¾ swath displacement upwind at the downwind edge of the field. • Do not apply when wind speeds exceed 15 mph at the application site. If the windspeed is greater than 10 mph, the boom length must be 65% or less of the wingspan for fixed wing aircraft and 75% or less of the rotor diameter for helicopters. Otherwise, the boom length must be 75% or less of the wingspan for fixed- wing aircraft and 90% or less of the rotor diameter for helicopters. • Do not apply during temperature inversions. Ground Boom Applications: • User must only apply with the release height recommended by the manufacturer, but no more than 4 feet above the ground or crop canopy. • Applicators are required to use a medium or coarser droplet size (ASABE S572). Do not apply when wind speeds exceed 15 miles per hour at the application site. • Do not apply during temperature inversions.

SPRAY DRIFT ADVISORIES THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.

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 are 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 recommended for the nozzle to produce the target spray volume and droplet size. • Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift.

BOOM HEIGHT – Ground Boom • For ground equipment, the boom should remain level with the crop and have minimal bounce. Controlling Droplet Size – Aircraft • Adjust Nozzles - Follow nozzle manufacturers’ recommendations for setting up nozzles. Generally, to reduce fine droplets, nozzles should be oriented parallel with the airflow in flight. RELEASE HEIGHT - Aircraft • Higher release heights increase the potential for spray drift. 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. Temperature inversions are characterized by increasing temperature with 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 APPLICATIONS DURING GUSTY WIND CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.

Sensitive Areas The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g., residential areas, bodies of water, known habitat for threatened or endangered species, nontarget crops) is minimal (e.g., when wind is blowing away from the sensitive areas).

USE RESTRICTIONS • DO NOT apply USH19004 to crops undersown with grass or legume species. • DO NOT make more than one application of USH19004 per 365 days. • DO NOT apply more than 13.7 fl oz/A (0.004 pounds thiencarbazone - methyl and 0.105 pounds acid equivalent of fluroxypyr ((4-amino-3,5-dichloro-6- fluoro-2-pyridinyl)oxy) acetic acid) of USH19004 per 365 days. • DO NOT apply more than 0.04 pounds/A per acre of Thiencarbazone-methyl from all sources per 365 days. • DO NOT apply more than 0.25 pounds/A of fluroxypyr from all sources per 365 days • DO NOT apply in combination with Dicamba containing products as grass control will be reduced. • DO NOT apply USH19004 in tank mixture with tebuconazole • DO NOT apply USH19004 through any type of irrigation system. • DO NOT drain or rinse equipment near desirable vegetation. • DO NOT apply to winter or spring wheat after jointing. • DO NOT harvest or graze wheat forage within 7 days after application. • DO NOT harvest winter wheat or spring wheat (including durum) for hay within 30 days after application. • DO NOT harvest wheat for grain or straw within 60 days after application in Minnesota, Montana, North Dakota, or South Dakota; and within 70 days in all other states.

USE PRECAUTIONS • Avoid spray drift from treated areas. Refer to the Spray Drift Management section of this label for additional information. • USH19004 is rainfast 1 hour after application to most weed species. Rainfall within 1 hour may result in reduced weed control. • Non-target plants may be adversely affected if the pesticide is allowed to drift from areas of application. To prevent damage to crops and other desirable plants, read and follow all directions and precautions on this label before using. • Environmental conditions which support vigorous growth of crop and weeds also result in highest herbicidal activity. Following application, symptoms of herbicidal activity may develop within several days. Speed of action depends on environmental conditions and increases with increasing temperature and moisture. • Applications of USH19004 in winter wheat or spring wheat (including durum) in combination with some EC herbicides may cause crop response (see tankmix section). • Applications during low temperatures (32ºF or lower), high temperatures (90ºF or greater), or to a crop under drought stress can cause crop injury.

APPLICATION INSTRUCTIONS • Weed infestations should be treated before they become competitive with the crop. Make applications to actively growing weeds. Thorough coverage of weeds is necessary to obtain good weed control. Weed control may be reduced when weeds are under stress due to severe weather conditions, drought, very cold temperatures, etc. Temperature range for optimal herbicidial activity is 55ºF to 75ºF. • Properly calibrate ground or aerial (fixed wing or helicopter) application equipment to apply USH19004 postemergence as a foliar spray. Use of nozzles and spray pressure that deliver medium to coarse spray droplets as indicated in the nozzle manufacturer’s catalogs and in accordance with ASABE Standard S-572 for optimum spray coverage and canopy penetration. • Avoid uneven spray distribution, skips, overlaps, and spray drift.

Aerial Application Calibrate the spray equipment prior to use. USH19004 should be applied in a minimum of 5 gallons of water per broadcast acre.

Ground Application Apply USH19004 broadcast in 10 or more gallons of water per acre.

WEED RESISTANCE MANAGEMENT For resistance management, USH19004 is a Group 2 (thiencarbazone-methyl) and Group 4 (fluroxypyr-methylheptyl) herbicide. Any weed population may contain or develop plants naturally resistant to USH19004 and other Group 2 and Group 4 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate resistance management strategies should be followed. To delay herbicide resistance take one or more of the following steps: • Rotate the use of USH19004 or other Group 2 and Group 4 herbicides within a growing season sequence or among growing seasons with different herbicide groups that control the same weeds in a field. • Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target weed species is available, use the less resistance-prone partner at a rate that will control the target weed(s) equally as well as the more resistance-prone partner. Consult your local extension service or certified crop advisor if you are unsure as to which active ingredient is currently less prone to resistance. • Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information related to herbicide use and crop rotation, and that considers tillage ( or other mechanical control methods), cultural ( e.g., higher crop seeding rates; precision fertilizer application method and timing to favor the crop and not the weeds), biological (weed- competitive crops or varieties) and other management practices. • Fields should be scouted prior to application to identify the weed species present and their growth stage to determine if the intended application will be effective. • Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of possible herbicide resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) surviving plants mixed with controlled individuals of the same species. If resistance is suspected, prevent weed seed production in the affected area by an alternative herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed. • If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switch to another management strategy or herbicide with a different mode of action, if available. • Contact your local extension specialist or certified crop advisors for additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes. • For further information or to report suspected resistance contact Bayer CropScience at 1-866-99BAYER (1-866-992-2937). You can also contact your pesticide distributor or university extension specialist to report resistance.

Order of Mixing USH19004 must be applied with clean and properly calibrated equipment. Prior to adding USH19004 to the spray tank, ensure that the spray tank, filters and nozzles have been thoroughly cleaned. In-line strainers and nozzle screens should be 50 mesh or coarser.

1. Fill the spray tank 1/4 to 1/2 full with clean water and begin agitation or bypass.
2. Add a listed tank mix partner, if desired. Please check Tank Mix section for optimum mixing suggestions
3. Add the specified rate of USH19004 directly to the spray tank. Maintain sufficient agitation during both mixing and application. DO NOT pre-slurry by adding any quantity of USH19004 to a small amount of water.
4. Fill the spray tank with balance of water needed.
5. Continue agitation during USH19004 application to ensure uniform spray coverage.

NOTE: USH19004 may settle if left standing without agitation. If the spray solution is allowed to stand for one hour or more, re-agitate the spray solution for a minimum of 10 minutes before application.

Equipment Cleanup Procedures

1. Drain the tank completely, and then wash out tank, boom and hoses with clean water. Drain again.
2. Half fill the tank with clean water and add ammonia (i.e., 3% domestic ammonia solution) at a dilution rate of 1% (i.e., 1 gallon of domestic ammonia for every 100 gallons of rinsate). Complete filling of the tank with water. Agitate/recirculate and flush through boom and hoses. Leave agitation on for 10 minutes. Drain tank completely.
3. Repeat step 2.
4. Remove nozzles and screens and soak them in a 1% ammonia solution. Inspect nozzles and screens and remove visible residues.
5. Flush tank, boom, and hoses with clean water.
6. Inspect tank for visible residues. If present, repeat step 2.

ROTATIONAL CROPS In areas where a crop is not specified, conduct a field bioassay as described in the FIELD BIOASSAY section.

Crop Rotational Interval Crop Rotational Interval Wheat 3 Months Lentils 9 Months

Soybean 4 Months Mustard Alfalfa 9 Months Oats, spring Barley Peas Canola Safflower Canaryseed Sorghum (grain) Chickpeas Sugarbeets Corn – Conventional Sunflowers Dry Beans Timothy Flax Potatoes 18 Months

Cover Crops Use of cover crops as a means of soil improvement, erosion control, weed and/or insect suppression, etc., following harvest in the fall is increasing. Planting of cover crops in fields treated with USH19004 is allowed as long as these cover crops are not grazed by livestock nor harvested for food. Cover crops are to be tilled under or chemically controlled with burndown herbicides in the spring. Many cover crops can be planted within 90-120 days after application of USH19004. However, all potential cover crops have not been evaluated for tolerance to USH19004 and significant injury may occur. Prior to seeding a cover crop, complete a successful field/ small scale bioassay to provide an indication of the level of tolerance to the prior USH19004 application. Refer to the “Field/Small Scale Bioassay” section.

Field/Small Scale Bioassay A field/ small scale bioassay must be completed before rotating to a cover crop other than those specified in the “Rotational Crop Restrictions” section of this label. To conduct an effective field bioassay, grow strips of the crop(s) you intend to grow the following season in a field previously treated with USH19004. The test strip should be placed in a controlled area and should include low areas and knolls, and include variations in soil such as type and pH. Crop response to the bioassay will determine if the crop(s) grown in the test strips can be grown safely in the areas previously treated with USH19004.

9

For an effective small scale bioassay, collect uniform samples of all soil types from the USH19004- treated field and place the soil into a sturdy container. Plant the desired cover crop into the soil, apply water and place the container in a warm, sunny area to allow germination and growth of the crop. Monitor growth of the cover crop over a three to four week period. If the cover crop emerges and grows normally, the risk to establish and grow the cover crop in the USH19004-treated field should be tolerable.

WEEDS CONTROLLED & PARTIALLY CONTROLLED

USH19004 effectively controls the following weeds when applied at the application timings recommended and when weeds are actively growing. Best control is achieved when grass weeds are treated between the 1-leaf to 1-tiller stage of growth and broadleaf weeds are between the 1-6 leaf stage of growth, unless otherwise indicated. USH19004 will have an effect on weeds that are larger than the recommended leaf stage; however the speed of activity and level of control may be reduced.
