ENVIRONMENTAL HAZARDS
This product is toxic to fish, aquatic invertebrates and freshwater/estuaries/marine
aquatic plants . 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 . Do not apply directly to water,
or to areas where surface water is present or to intertidal areas below the mean
high water mark . Drift and runoff may be hazardous to aquatic organisms in water
adjacent to treated areas . Do not contaminate water when disposing of equipment
washwater or rinsate .
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 .
GROUNDWATER ADVISORY: Degradates of prothioconazole are known to leach
through soil into groundwater under certain conditions as a result of label use .
Several trifloxystrobin degradates have properties and characteristics associated
with chemicals detected in ground water . These chemicals may leach into
groundwater if used in areas where soils are permeable, particularly where the
water table is shallow .
DIRECTIONS FOR USE
It is a violation of federal law to use this product in a manner inconsistent with
its labeling.

PRODUCT INFORMATION
Stratego® YLD Fungicide is a broad-spectrum fungicide for improved plant
health and control of certain diseases in barley, chickpea, corn, dry peas, lentils,
soybean, and wheat . Stratego YLD Fungicide contains two fungicide active
ingredients 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 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
appearing on this label . Equipment must be properly calibrated before use .
Do not apply by aerial application in New York State .
FUNGICIDE RESISTANCE MANAGEMENT (FRAC) RECOMMENDATIONS
For resistance management, please note that Stratego YLD Fungicide contains
both a Group 3 (prothioconazole) and Group 11
(trifloxystrobin) fungicide . Any fungal population may contain individuals naturally
resistant to Stratego YLD 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 Stratego YLD 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 .
Application/Spray Equipment
Stratego YLD Fungicide may be applied by either, ground, aerial and/or
chemigation equipment . Refer to the USE DIRECTIONS section of this label for
approved applications for each crop .
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 control . For ground application
equipment, a minimum of 10 gal/A is recommended . For aerial application
equipment, a minimum of 2 gal/A is recommended unless stated elsewhere on
this label .
4
Aerial Application to Corn and Soybeans:
Aerial applications of Stratego YLD Fungicide to corn and soybeans may be
applied using water volumes of 2 or more gallons of spray solution per acre
(gpa) . An adjuvant may be used to improve spray coverage . Refer to the
adjuvant product label for specific directions .
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 application . Be
certain that nozzles are the same size and uniformly 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 .
Use screens to protect the pump and to prevent nozzles from clogging . 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, and where required, at nozzles . Check nozzle
manufacturers recommendations .
For information on spray equipment and calibration, consult sprayer
manufacturers and state recommendations . For specific local directions and
spray schedules, consult the current state agricultural experiment station
recommendations .
Application Through Irrigation Systems (Chemigation) Apply Stratego YLD
Fungicide through irrigation equipment only to crops for which chemigation
is specified on this label.
Stratego YLD 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
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 YLD 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 YLD Fungicide through irrigation
equipment use the lowest obtainable water volume while maintaining uniform
distribution . Run the system at 80-95% of the manufacturers rated capacity .
Using water, determine the injection pump output when operated at normal line
pressure . Determine the amount of Stratego YLD Fungicide required to treat the
area covered by the irrigation system . Add the required amount of Stratego YLD
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 YLD 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 YLD Fungicide solution has cleared the sprinkler head .
Solid Set, Hand Move, and Moving Wheel Irrigation Equipment
When applying Stratego YLD Fungicide through irrigation equipment use the
lowest obtainable water volume while maintaining uniform distribution . Determine
the amount of Stratego YLD Fungicide required to treat the area covered by the
irrigation system . Add the required amount of Stratego YLD 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 YLD Fungicide solution has cleared the last sprinkler head .
Mixing Procedures
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 .
Stratego YLD Fungicide Alone: Add 1/2 of the required amount of water to
the spray tank and start the agitator . Add the proper amount of Stratego YLD
Fungicide and then add the rest of the water . Begin application of the solution
when the Stratego YLD Fungicide has completely dispersed in the mix water .
Maintain agitation until all of the mixture has been applied .
Stratego YLD 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 packaged in water-soluble packaging, wettable powders, and
water-dispersible granular products first, next Stratego YLD Fungicide, followed
by any other liquid flowables, then emulsifiable concentrates, and last, liquid
soluble products . Always allow each tank mix partner to become fully dispersed
before adding the next product . Continue to provide agitation while adding the
remainder of the water . Maintain agitation until all of the mixture has been applied .
6
Note: When using Stratego YLD Fungicide in tank mixtures, all products in
water-soluble packaging must be added to the tank before any other tank mix
partner, including Stratego YLD 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 YLD 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 product label . Do not exceed the labels dosage rate . The most
restrictive label precautions and limitations must 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 labeled .
Stratego YLD Fungicide is compatible with most insecticide, fungicide, and
foliar nutrient products . However, the physical compatibility of Stratego YLD
Fungicide with tank mix partners must be tested before use . To determine the
physical compatibility of Stratego YLD 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 emulsifiable concentrates, and last, liquid soluble
products such as Stratego YLD Fungicide . After thoroughly mixing, let stand for
at least 5 minutes . If the combination remains mixed or can be remixed readily, it
is probably 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 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 .
MANDATORY SPRAY DRIFT MANAGEMENT
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 I0 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 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 .
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 .

Stratego YLD Fungicide as a
broadcast foliar spray at V4
(4 leaf collar) to V7 (7 leaf
collar) growth stages when
conditions are favorable
for disease development.
For season-long control
of these diseases and the
diseases listed below, apply
a sequential treatment of
Stratego YLD Fungicide at
4.0-5.0 fl oz/acre from VT
(lowest branch on the tassel
is visible but the silks have

Apply Stratego YLD Fungicide
when disease first appears
and continue on a 7- to
14-day interval if conditions
for disease development
persist.
Use the higher rates and
shorter intervals when
disease pressure is severe.
Do not use adjuvants in
sprays made between V8 (8
leaf collar) and VT (lowest
branch of the tassel is visible
but the silks have not yet
emerged).
General Comments: Use of an adjuvant may enhance the performance of Stratego YLD
Fungicide.
Stratego YLD Fungicide may be applied by ground, air, or chemigation.
Application of Stratego YLD Fungicide is not recommended at times when corn is under severe
environmental stress conditions.
Do not apply more than 10 fl oz (0.082 lbs prothioconazole, 0.245 lbs trifloxystrobin) of Stratego
YLD Fungicide per acre per year. Do not apply within 14 days of harvest for grain and fodder.
Forage may be harvested the same day of application. Do not apply more than 2 sequential
applications of Stratego YLD Fungicide or any other QoI Group 11 fungicide without alternation
with a fungicide from another group.
