• Harmful if swallowed, inhaled or absorbed through skin. 
• Prolonged or frequently repeated skin contact may cause allergic reactions in some individuals. 
• Avoid contact with skin, eyes, and clothing. Wear protective eyewear. Wash thoroughly with soap and water after handling and 
before eating, drinking, chewing gum, or using tobacco. Avoid breathing vapor or spray mist. 
 
PERSONAL PROTECTIVE EQUIPMENT (PPE) 
 
Applicators and other handlers must wear: 
• Long-sleeved shirt and long pants 
• Shoes plus socks 
• Chemical-resistant gloves made of any waterproof material. 
 
USER SAFETY REQUIREMENTS 
Follow manufacturer's instructions for cleaning/maintaining PPE. If no such instructions for washables exist, use detergent and hot 
water. Keep and wash PPE separately from other laundry. 
 
USER SAFETY RECOMMENDATIONS 
• Users should wash hands before eating, drinking, chewing gum, using tobacco or using the toilet. 
• Users should remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. 
• Users should remove PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as 
possible, wash thoroughly and change into clean clothing. 
 
ENGINEERING CONTROLS 
When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in the Worker Protection

ENVIRONMENTAL HAZARDS 
This pesticide is toxic to fish and aquatic invertebrates. Applying this product when rain is not predicted for the next 24 hours will help 
reduce potential risk to aquatic invertebrates by reducing pesticide runoff from the treatment area into water bodies. Drift and runoff may 
be hazardous to aquatic organisms in water adjacent to treated areas. DO NOT apply directly to water, or to areas where surface water 
is present, or to intertidal areas below the mean high-water mark. 
 
Surface Water Advisory 
This product may impact surface water quality due to runoff of rainwater. 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 months or more 
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 prothioconazole and degradates 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 
Degradates of prothioconazole are known to leach through soil into groundwater under certain conditions as a result of label use. These 
chemicals may leach into groundwater if used in areas where soils are permeable, particularly where the water table is shallow. 
 
Run Off Management 
Drift and runoff are hazardous to aquatic organisms in water adjacent to treated areas. This product has a high potential for runoff for 
several months or more after application. Poorly draining soils and soils with shallow water tables are more prone to produce runoff that 
contains this product. 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 for contamination of water from rainfall-runoff. Runoff of this 
product will be reduced by avoiding applications when rainfall is forecasted to occur within 48 hours.

PRODUCT INFORMATION 
USF 0728 325 SC Fungicide: 
• is a broad spectrum fungicide for the control of certain diseases of Barley, Corn, Cotton, Dried Shelled Pea and Bean - Except 
Soybean (Subgroup 6C), Flax, Peanut, Potato, Soybean, Sugar beets, Sweet corn and Wheat; 
• works by interfering with both energy and cell membrane production by plant pathogenic fungi. Equipment must be properly 
calibrated before use. 
 
APPLICATION INSTRUCTIONS 
• USF 0728 325 SC Fungicide may be applied by ground, air (except in New York), or chemigation. 
• Use of an adjuvant may enhance the performance of USF 0728 325 SC Fungicide. 
 
Aerial Application 
Avoid application under conditions when uniform coverage cannot be obtained or when excessive spray drift may occur. DO NOT apply 
directly to humans or animals. Not registered for aerial application in New York State. Refer to specific crop sections for water carrier 
volume recommendations. 
 
Ground Application 
Applications using sufficient water volume to provide thorough and uniform coverage generally provide the most effective disease 
control. Refer to specific crop sections for water carrier volume recommendations. 
 
Ground Application (Broadcast) 
Equip sprayers with nozzles that provide accurate and uniform application. Nozzle selection, spraying pressures, carrier volume and 
application speeds are critical for maximum efficacy. Select nozzles that deliver Fine to Medium droplets and operate them within the 
pressures specified by the manufacturer. Adjust application speeds to allow for canopy penetration and coverage of the leaf surface. Be 
certain that nozzles are the same size and uniformly spaced across the boom. Calibrate the sprayer before use and replace worn or 
damaged nozzles. 
 
Use a pump with sufficient agitation capacity in the tank to keep the mixture in suspension. This requires recirculation of 10% of the tank 
volume per minute. Use jet agitators or a liquid spurge tube for vigorous agitation. 
 
Use screens to protect the pump and to prevent nozzles from clogging. Check nozzle manufacturer’s recommendations. 
 
For information on spray equipment and calibration, consult sprayer manufacturer’s and/or state recommendations. 
For specific local directions and spray schedules, consult the current state agricultural experiment station recommendations.

6 
 
USE RESTRICTIONS 
• Under certain conditions conducive to extended infection periods, additional fungicide applications beyond the number allowed 
by this label may be needed. Under these conditions, use another fungicide registered for the crop/disease. 
• DO NOT apply more than 2 sequential applications of USF 0728 325 SC Fungicide or any other QoI Group 11 fungicide without 
alternation with a fungicide from another group. 
• Not registered for aerial application in New York State. 
• DO NOT use with handheld application equipment, including mechanically pressurized spray gun, backpack or tank pressurized 
spray gun or handheld boom applicators. 
Refer to the specific use directions and restrictions in each Crop table. 
 
 
RESISTANCE MANAGEMENT 
For resistance management, please note that USF 0728 325 SC Fungicide contains both a Group 3 (prothioconazole) and Group 11 
(trifloxystrobin) fungicide. Any fungal population may contain individuals naturally resistant to USF 0728 325 SC Fungicide and other 
Group 3 or Group 11 fungicides. A gradual or total loss of pest control may occur over time if these fungicides are used repeatedly in the 
same fields. Appropriate resistance-management strategies should be followed. 
To delay fungicide resistance, take one or more of the following steps: 
• Rotate the use of USF 0728 325 SC Fungicide or other Group 3 or Group 11 fungicides within a growing season sequence with 
different groups that control the same pathogens. 
• Use tank mixtures with fungicide from a different group that are equally effective on the target pest when such use is permitted. 
Use at least the minimum application rate as labeled by the manufacturer. 
• Adopt an integrated disease management program for fungicide use that includes scouting, uses historical information related 
to pesticide use, and crop rotation, and which considers host plant resistance, impact of environmental conditions on disease 
development, disease thresholds, as well as cultural, biological and other chemical control practices. 
• Where possible, make use of predictive disease models to effectively time fungicide applications. Note that using predictive 
models alone is not sufficient to manage resistance. 
• Monitor treated fungal/bacterial populations for resistance development. 
• Contact your local extension specialist or certified crop advisor for any additional pesticide resistance-management and/or IPM 
recommendations for specific crops and pathogens. 
• 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.

CHEMIGATION 
USF 0728 325 SC Fungicide alone or in combination with other pesticides which are registered for application through irrigation systems, 
may be applied through irrigation systems. Apply this product only through center pivot, solid set, hand move, or moving wheel irrigation 
systems. DO NOT apply this product through any other type of irrigation system. Illegal pesticide residues in the crop can result from 
non-uniform distribution of treated water. If you have questions about calibration, you should contact State Extension Service specialists, 
equipment manufacturers, or other experts. DO NOT connect an irrigation system (including greenhouse systems) used for pesticide 
application to a public water system, unless the pesticide label-prescribed safety devices for public water systems are in place. A person 
knowledgeable of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall 
shut the system down and make necessary adjustments should the need arise. 
Operating Instructions 
1. The system must contain a functional check-valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation 
pipeline to prevent water-source contamination from backflow. 
2. The pesticide injection pipeline must contain a functional, automatic, quick-closing check-valve to prevent the flow of fluid back toward 
the injection pump. 
3. The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on the intake side of 
the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation 
system is either automatically or manually shut down. 
4. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump 
motor stops. 
5. The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor when the water 
pressure decreases to the point where pesticide distribution is adversely affected. 
6. Systems must use a metering pump, such as a positive displacement injection pump (e.g.,diaphragm pump), effectively designed and 
constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock. 
7. DO NOT apply when wind speed favors drift beyond the area intended. 
Center Pivot Irrigation Equipment 
Notes: (1) Use only with drive systems which provide uniform water distribution. (2) DO NOT use end guns when chemigating USF 0728 
325 SC Fungicide through center pivot systems because of non-uniform application. 
Determine the size of the area to be treated. Determine the time required to apply 1/8-1/2 inch of water over the area to be treated when 
the system and injection equipment are operated at normal pressures as recommended by the equipment manufacturer. When applying 
USF 0728 325 SC Fungicide through irrigation equipment use the lowest obtainable water volume while maintaining uniform distribution. 
Run the system at 80-95% of the manufacturer’s rated capacity. Using water, determine the injection pump output when operated at 
normal line pressure. Determine the amount of USF 0728 325 SC Fungicide required to treat the area covered by the irrigation system. 
Add the required amount of USF 0728 325 SC Fungicide and sufficient water to meet the injection time requirements to the solution tank. 
Make sure the system is fully charged with water before starting injection of the USF 0728 325 SC Fungicide solution. Time the injection 
to last at least as long as it takes to bring the system to full pressure. Maintain constant solution tank agitation during the injection 
period. Continue to operate the system until the USF 0728 325 SC Fungicide solution has cleared the sprinkler head. 
Solid Set, Hand Move, and Moving Wheel Irrigation Equipment 
When applying USF 0728 325 SC Fungicide through irrigation equipment use the lowest obtainable water volume while maintaining 
uniform distribution. Determine the amount of USF 0728 325 SC Fungicide required to treat the area covered by the irrigation system. 
Add the required amount of USF 0728 325 SC Fungicide into the same quantity of water used to calibrate the injection period. Operate 
the system at the same pressure and time interval established during the calibration. Stop injection equipment after treatment is 
completed. Continue to operate the system until the USF 0728 325 SC Fungicide solution has cleared the last sprinkler head.

SPRAY DRIFT 
 
Aerial Applications 
• For aerial applications, DO NOT apply when wind speeds exceed 15 mph at the application site. If the wind speed 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 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 must use ½ swath displacement upwind at the downwind edge of the field. 
• DO NOT apply during temperature inversions. 
 
Ground Boom Applications 
• Apply with the nozzle 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. I). 
• 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 A VOIDING 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. 
 
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. 
 
BOOM HEIGHT-Ground Boom 
For ground equipment, the boom should remain level with the crop and have minimal bounce. 
 
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.

COMPATIBILITY TESTING AND TANK MIX PARTNERS 
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. 
When using USF 0728 325 SC Fungicide in tank mixtures, all products in water-soluble packaging should be added to the tank before 
any other tank-mix partner, including USF 0728 325 SC Fungicide. Allow the water-soluble packaging to completely dissolve and the 
product(s) to completely disperse before adding any other tank-mix partner to the tank. If using USF 0728 325 SC Fungicide in a tank 
mixture, observe all directions for use, crop/sites, use rates, dilution ratios, precautions, and limitations which appear on the tank-mix 
partner product label. No label dosage rate should be exceeded, and the most restrictive label precautions and limitations should be 
followed. This product must not be mixed with any product which prohibits such mixing. Tank mixtures or other applications of products 
referenced on this label are permitted only in those states in which the referenced products are registered. 
 
Compatibility 
USF 0728 325 SC Fungicide is compatible with most insecticide, fungicide, and foliar nutrient products. However, the physical 
compatibility of USF 0728 325 SC Fungicide with tank-mix partners should be tested before use. To determine the physical compatibility 
of USF 0728 325 SC Fungicide with other products, use a jar test, as described below. 
 
Using a quart jar, add the proportionate amounts of the products to 1 qt. of water. Add wettable powders and water-dispersible granular 
products first, then liquid flowables, and emulsifiable concentrates last. After thoroughly mixing, let stand for at least 5 minutes. If the 
combination remains mixed or can be remixed readily, it is physically compatible. Once compatibility has been proven, use the same 
procedure for adding required ingredients to the spray tank. 
 
The crop safety of all potential tank mixes including additives and other pesticides on all crops has not been tested. Before applying any 
tank mixture not specifically recommended on this label, the safety to the target crop should be confirmed. To test for crop safety, apply 
USF 0728 325 SC Fungicide to the target crop in a small area and in accordance with label instructions for the target crop. 
 
Order of Mixing 
Prepare no more spray mixture than is needed for the immediate operation. Thoroughly clean spray equipment before using this product. 
Vigorous agitation is necessary for proper dispersal of the product. Maintain maximum agitation throughout the spraying operation. DO 
NOT let the spray mixture stand overnight in the spray tank. Flush the spray equipment thoroughly following each use and apply the 
rinsate to a previously treated area. 
 
USF 0728 325 SC Fungicide Alone: Add approximately 1/2 of the required amount of water to the mix tank. With the agitator running, 
add the USF 0728 325 SC Fungicide to the tank. Continue agitation while adding the remainder of the water. Begin application of the 
solution after the USF 0728 325 SC Fungicide has completely and uniformly dispersed into the mix water. Maintain agitation until all of 
the mixture has been applied. 
 
USF 0728 325 SC Fungicide + Tank Mix Partners: Add approximately 1/2 of the required amount of water to the mix tank. Start the 
agitator running before adding any tank-mix partners. In general, tank-mix partners should be added in this order: 
1. Products packaged in watersoluble packaging 
2. Wettable powders, wettable granules (dry flowables) 
3. USF 0728 325 SC Fungicide 
4. Other liquid flowables 
5. Emulsifiable concentrates 
6. Water soluble liquids 
7. Adjuvents 
Always allow each tank-mix partner to become fully and uniformly dispersed before adding the next product. Provide sufficient agitation 
while adding the remainder of the water. Maintain agitation until all of the mixture has been applied.
