PRECAUTIONARY STATEMENTS 
HAZARDS TO HUMANS AND DOMESTIC ANIMALS 
CAUTION 
Harmful if swallowed, absorbed through skin, or inhaled. Causes moderate eye irritation. Avoid breathing vapor or spray mist or contact 
with skin, eyes or clothing. Wash thoroughly with soap and water after handling and before eating, drinking, chewing gum, or using 
tobacco. 
Personal Protective Equipment (PPE) 
Applicators and other handlers must wear: 
x Long-sleeved shirt and long pants 
x Shoes plus socks 
x Chemical resistant gloves made of any waterproof material 
 
Follow manufacturer’s instructions for cleaning/maintaining PPE. If no such instructions exist for washables, use detergent and hot 
water. Keep and wash PPE separately from other laundry. 
 
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 [40 CFR 170.607 (d)(e)(f)], the handler PPE requirements may be reduced or modified as 
specified in the WPS. 
User Safety Recommendations 
Users should: 
• Wash hands before eating, drinking, chewing gum, using tobacco, or using the toilet. 
• Remove clothing immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. 
• Wash the outside of gloves before removing. As soon as possible, wash thoroughly and change into clean clothing. 
 
ENVIRONMENTAL HAZARDS 
This pesticide is toxic to fish, aquatic invertebrates, and freshwater/estuarine/marine aquatic plants. Applying this product when rain is 
not predicted for the next 24 hours will help reduce potential risk by reducing pesticide runoff from the treatment area into water bodies. 
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. 
 
Groundwater 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. Several trifloxystrobin degradates have properties and characteristics associated with chemicals detected in 
ground water. 
 
Surfacewater 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 pond, streams and springs will reduce the potential loading of prothioconazole and 
degradates from runoff water and sediment. Runoff of his product will be reduced by avoiding application when rainfall or irrigation is 
expected to occur within 48 hours.

GENERAL INFORMATION 
Stratego 731 Fungicide is a broad-spectrum fungicide for the impr oved plant health and control of certain diseases in soybeans. 
Stratego 731 Fungicide contains two fungicide active ingredient s and works by interfering with respiration in plant pathogenic fungi, 
inhibition of spore germination, and by blocking fungal growth. 
UNDER CERTAIN CONDITIONS CONDUCIVE TO EXTENDED INFE CTION 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 APPEARING ON THIS LABEL. 
Equipment must be properly calibrated before use. 
 
FUNGICIDE RESISTANCE MANAGEMENT (FRAC) RECOMMENDATIONS 
For resistance management, please note that Stratego 731 Fungicide contains both a Group 3 (prothioconazole) and Group 11 
(trifloxystrobin) fungicide. Any fungal population may contain individuals naturally resistant to Stratego 731 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: 
x Rotate the use of Stratego 731 Fungicide or other Group 3 or Group 11 fungicides within a growing season sequence with 
different groups that control the same pathogens. 
x Use tank mixtures with fungicides 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. 
x Adopt an integrated disease management program for fungicide us e 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. 
x Where possible, make use of predictive disease models to effect ively time fungicide applications. Note that using predictive 
models alone is not sufficient to manage resistance. 
x Monitor treated fungal/bacterial populations for resistance development. 
x Contact your local extension specialist or certified crop advis or for any additional pesticide resistance-management and/or IPM 
recommendations for specific crops and pathogens. 
x 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. 
 
Application/Spray Equipment 
 
Stratego 731 Fungicide may be applied by either, ground, aerial and/or chemigation equipment. 
Thorough coverage is necessary to provide good disease control. Applications using sufficient water volume to provide thorough and 
uniform coverage generally provide the most effective disease c ontrol. For ground application equipment, a minimum of 10 gal/A is 
recommended. For aerial equipment use a minimum of 2 gal/A. 
Refer to the USE DIRECTIONS section of this label for approved applications for each crop. 
 
Aerial Application to Soybeans: 
Aerial applications of Stratego 731 Fungicide to soybeans may be applied using water volumes of 2 or more gallons of spray solution 
per acre (gpa). For application volumes of 2 to 5 gpa, the spray solution must contain from 0.5-1.0 pint/acre crop oil concentrate that 
has emulsified properties. Use the higher rate as weather conditions become less conducive for spray droplets to reach the target 
application zone (temperatures > 85
◦F, relative humidity <60%) or when application volume is less than or equal to 3 gpa. 
Equip and properly calibrate sprayers with appropriate nozzles, pumping pressure and sprayer height to provide medium spray droplets 
that will penetrate throughout the crop canopy. Continually monitor spray applications to maintain correct droplet size and crop canopy 
penetration. 
Broadcast Ground Sprayers: 
Equip sprayers with nozzles that provide accurate and uniform appl ication. Be certain that nozzles are the same size and unifo rmly 
spaced across the boom. Calibrate sprayer before use, and replace worn or damaged nozzles. 
Use a pump with the capacity to: (1) maintain a minimum of 35 psi at nozzles, and (2) provide sufficient agitation in the tank to keep the 
mixture in suspension – this requires recirculation of 10% of the tank volume per minute. Use a jet agitator or liquid sparge tube for 
agitation.

5 
 
Use screens to protect the pump and to prevent nozzles from clogg ing. Screens placed on the suction side of the pump should be 16-
mesh or coarser. Do not place a screen in the recirculation line. Use 50-mesh or coarser screens between the pump and boom, a nd 
where required, at nozzles. Check nozzle manufacturer’s recommendations. 
For information on spray equipment and calibration, consult spra yer manufacturers and state recommendations. For specific loca l 
directions and spray schedules, consult the current state agricultural experiment station recommendations. 
 
Application Through Irrigation Systems (Chemigation) 
Stratego 731 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. 
Apply Stratego 731 Fungicide through irrigation equipment only to crops for which chemigation is specified on this label. 
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 Stratego 
731 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 Stratego 731 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 Stratego 731 Fungicide required to treat the area covered by the irrigation 
system. Add the required amount of Stratego 731 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 Stratego 731 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 Stratego 731 Fungicide solution has cleared the sprinkler head. 
 
Solid Set, Hand Move, and Moving Wheel Irrigation Equipment 
When applying Stratego 731 Fungicide throug h irrigation equipment use the lowest obtainable water volume while maintaining unif orm 
distribution. Determine the amount of Stratego 731 Fungicide requir ed to treat the area covered by the irrigation system. Add
 the 
required amount of Stratego 731 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 Stratego 731 Fungicide solution has cleared the last sprinkler head. 
Mixing Procedures 
Prepare no more spray mixture than is needed for the immediate o peration. Thoroughly clean spray equipment before using this 
product. Vigorous agitation is necessary for proper dispersal of the product. Maintain maximum agitation throughout the spray ing 
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. 
Stratego 731 Fungicide Alone: Add 1/2 of the required amount of water to the sp ray tank and start the agitator. Add the proper 
amount of Stratego 731 Fungicide and then add the rest of the water. Begin application of the solution when the Stratego 731 
Fungicide has completely dispersed in the mix water. Maintain agitation until all of the mixture has been applied. 
Stratego 731 Fungicide + Tank Mixtures: Add 1/2 of the required amount of water to the spray tank and start the agitator. In 
general, add tank mix partners in this order: products pa ckaged in water-soluble packaging, wettable powders, and water-disper sible 
granular products first, next liquid flowables, then emulsifiab le concentrates, and last, liquid soluble products such as Strat ego 731

6 
 
Fungicide. Always allow each tank mix partner to become fully dispersed before adding the next product. Continue to provide a gitation 
while adding the remainder of the water. Maintain agitation until all of the mixture has been applied. 
Note: When using Stratego 731 Fungicide in tank mixtures, all produc ts in water-soluble packaging must be added to the tank before 
any other tank mix partner, including Stratego 731 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 Stratego 731 Fungicide in a tank mixture, observe all directions for use, crop/sites, use rates, dilution ratios, prec autions, and 
limitations which appear on the tank mix product label. Do not exceed the label’s dosage rate, and the most restrictive label 
precautions and limitations must be followed. This product must not be mixed with any product which prohibits such mixing. Ta nk 
mixtures, or other applications of products referenced on this label, are permitted only in those states in which the reference d products 
are labeled. 
Stratego 731 Fungicide is compatible with most insecticide, fu ngicide, and foliar nutrient products. However, the physical com patibility 
of Stratego 731 Fungicide with tank mix partners must be tested bef ore use. To determine the physical compatibility of Strateg o 731 
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, next liquid flowables, then em ulsifiable concentrates, and last, liquid soluble products such as Stratego 731 F ungicide. 
After thoroughly mixing, let stand for at least 5 minutes. If the combination remains mixed or can be remixed readily, it is p robably 
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 INCLUD ING ADDITIVES AND OTHER PESTICIDES ON ALL CROPS HAS 
NOT BEEN TESTED. BEFORE APPLYING ANY TANK MIXTURE NO T LISTED ON THIS LABEL, THE SAFETY TO THE TARGET 
CROP MUST BE CONFIRMED. 
Aerial Application: Avoid application under conditions where uniform coverage cannot be obtained or where excessive spray drift 
may occur. Do not apply directly to humans or animals. 
 
SPRAY DRIFT 
Aerial Applications: 
x 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. 
x Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unle ss a greater application 
height is necessary for pilot safety. 
x Applicators must use ½ swath displacement upwind at the downwind edge of the field. 
x Do not apply during temperature inversions. 
 
Ground Boom Applications: 
x Apply with the nozzle height recommended by the manufact urer, but no more than 4 feet above the ground or crop 
canopy. 
x Applicators are required to use a medium or coarser droplet size (ASABE S572. I). 
x Do not apply when wind speeds exceed 15 miles per hour at the application site. 
x 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 
x 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. 
x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. 
x Spray Nozzle - Use a spray nozzle that is designed for the in tended application. Consider using nozzles designed to reduce 
drift. 
 
Controlling Droplet Size –Aircraft 
x 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.

7 
 
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. A void 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.

the higher rate as weather conditions become less conducive for spray droplets to reach the target application zone (temperatures > 
85◦F, relative humidity <60%) or when application volume is less than or equal to 3 gpa. 
 
Do not use with handheld application equipment, including mechanically pressurized spray gun, backpack or tank pressurized spray 
gun or handheld boom applicators. 
 
Stratego 731 Fungicide may be applied by ground, air or chemigation.
