Environmental Hazards
Azoxystrobin is toxic to freshwater, estuarine/marine fish and aquatic invertebrates.
Azoxystrobin can be persistent for several months or longer. For terrestrial uses 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 wash-water or rinsate.
Ground Water Advisory
Azoxystrobin, a degradate of azoxystrobin and cyproconazole are known to leach
through soil to ground water under certain conditions as a result of label use. This
product may leach into ground water if used in areas where soils are permeable,
particularly where the water table is shallow.
Quadris Xtra
Page 4
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 a 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 azoxystrobin and a
degradate of azoxystrobin 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.
Notify State and/or Federal authorities and Syngenta immediately if you observe any
adverse environmental effects due to use of this product.

USE INFORMATION
Quadris Xtra is a broad spectrum, preventative fungicide with systemic and curative
properties recommended for the control of many important plant diseases. Quadris Xtra
may be applied as a foliar spray in alternating spray programs or in tank mixes with other
crop protection products. All applications must be made according to the use directions
that follow.
USE PRECAUTIONS
Do not use in nurseries, greenhouses or landscape plantings.
Under certain conditions conducive to extended infection periods, use another registered
fungicide for additional applications if the maximum amount of product has been applied.
The active ingredient(s) in this product may have effects on federally listed threatened
and endangered species or critical habitat in some counties. When using this product,
you must follow the measures contained in the County Bulletin for the county in which
you are applying the pesticide. To determine whether your County has a Bulletin consult
http://www.epa.gov/espp. Bulletins also may be available from local pesticide dealers,
extension offices, or State pesticide agencies.
ROTATIONAL CROPS
Soybeans, corn, or wheat may be replanted immediately, if crop is lost. Cereal grains
other than wheat can be planted 180 days after last application. Cotton can be planted
180 days after last application. All other crops (including leafy vegetables) can be planted
270 days after last application.
PHYTOTOXICITY
Quadris Xtra demonstrates some phytotoxic effects when mixed with products that are
formulated as ECs. These effects are enhanced if applications are made under cool,
cloudy conditions and these conditions remain for several days following application. In
addition, adjuvants that contain some form of silicone can contribute to phytotoxicity.
Under certain environmental conditions, tank mixes of Quadris Xtra plus herbicides and/or
fertilizers may cause crop injury.
ATTENTION
Quadris Xtra is extremely phytotoxic to certain apple varieties.
Quadris Xtra
Page 7
AVOID SPRAY DRIFT. Extreme care must be used to prevent injury to apple trees (and
apple fruit).
DO NOT spray Quadris Xtra where spray drift may reach apple trees.
DO NOT use spray equipment which has been previously used to apply Quadris Xtra to
spray apple trees. Even trace amounts can cause unacceptable phytotoxicity to certain
apple and crabapple varieties.
AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR.
INTEGRATED PEST (DISEASE) MANAGEMENT
Quadris Xtra should be integrated into an overall disease and pest management strategy
whenever the use of a fungicide is required. Cultural practices known to reduce disease
development should be followed. The SPECIFIC USE DIRECTIONS section in this label
identifies specific IPM recommendations for each crop. Consult your local agricultural
authorities for additional IPM strategies established for your area. Quadris Xtra may be
used in State Agricultural Extension advisory (disease forecasting) programs which
recommend application timing based on environmental factors favorable for disease
development.
RESISTANCE MANAGEMENT
AZOXYSTROBIN GROUP
11 FUNGICIDE
CYPROCONAZOLE GROUP 3 FUNGICIDE
For resistance management, please note that Quadris Xtra contains both azoxystrobin,
a strobilurin fungicide in Group 11 and cyproconazole, a triazole fungicide in Group 3.
Any fungal population may contain individuals naturally resistant to either or both of the
active ingredients in Quadris Xtra and other Group 11 or Group 3 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.
Follow specific crop recommendations that limit the total number of sprays on a crop and
the required alternations with fungicides from other resistance management groups. In
situations requiring multiple sprays (more than two), develop season long spray programs
for Group 11 (QoI) fungicides. The program should meet the goal of no more than 1/3 of
the total sprays per season, when a Group 11 fungicide is used as a solo product, or 1/2
the total sprays when a Group 11 fungicide is used in a mixture. Programs that include
both solo Group 11 products and/or mixes containing Group 11 products should be no
more than ½ the total sprays.
Quadris Xtra
Page 8
Quadris Xtra should not be alternated or tank mixed with any fungicide to which resistance
has already developed.
To delay fungicide resistance, take one or more of the following steps:
x Rotate the use of Quadris Xtra or other Group 11 and 3 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 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.
x 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.
x Monitor treated fungal populations for resistance development.
x Contact your local extension specialist or certified crop advisor 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 Syngenta Crop
Protection at 1-866-796-4368. You can also contact your pesticide distributor or
university extension specialist to report resistance.

SPRAY EQUIPMENT
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.
Use a pump with capacity to: (1) maintain at least 35-40 psi at nozzles, and (2) provide
sufficient agitation in tank to keep mixture in suspension - this requires recirculation of
10% of tank volume per minute. Use a jet agitator or liquid sparge tube for agitation. Do
not air sparge.
Quadris Xtra is a suspoemulsion concentrate. It is suggested that screens be used to
protect the pump and to prevent nozzles from clogging. Screens placed on suction side
of 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
the nozzles. Check nozzle manufacturer’s recommendations.
For more information on spray equipment and calibration, consult sprayer manufacturers
and state recommendations. For specific local directions and spray schedules, consult
the current state and local agricultural recommendations.
SPRAYING/MIXING
Quadris Xtra may be applied with all types of spray equipment commonly used for making
ground and aerial applications. Do not apply Quadris Xtra through any type of ultra low
volume (ULV) spray system. Proper adjustments and calibration of spraying equipment
to give good canopy penetration and coverage is essential for good disease control.
Higher rates in the rate range and/or shorter spray intervals may be required under
conditions of heavy infection pressure, highly susceptible varieties, or when
environmental conditions conducive to disease exist.
For ground applications, apply Quadris Xtra in a minimum of 10 gallons of water volume
for adequate coverage and canopy penetration. For aerial applications, apply Quadris
Xtra according to local recommendations.
Prepare no more spray mixture than is required for the immediate operation. Thoroughly
clean spray equipment before using this product. Agitate the spray solution before and
during application. Rinse spray tank thoroughly with clean water after each day’s use
and dispose of pesticide rinsate by application to an already treated area.
Quadris Xtra Alone: Add 1/2 - 2/3 of the required amount of water to the spray of mixing
tank, with the agitator running, add Quadris Xtra to the tank and continue agitation while
adding the remainder of the water. Begin application of the spray solution after the
Quadris Xtra
Page 10
Quadris Xtra has completely dispersed into the mix water and maintain agitation until all
of the mixture has been sprayed.
Quadris Xtra + Tank Mixtures: Do not combine Quadris Xtra in the spray tank with
pesticides, surfactants, or fertilizers, unless compatibility charts or your own prior use has
shown that the combination is physically compatible, effective, and non-injurious to the
crop under your conditions of use. To determine physical compatibility of Quadris Xtra
and other products, use a jar test. 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 (suspoemulsions), 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.
Add 1/2 - 2/3 of the required amount of water to the spray or mixing tank. With the agitator
running, add the tank mix partner into the tank. Allow the material to completely dissolve
and disperse into the mix water. Continue agitation while adding the remainder of the
water and the Quadris Xtra to the spray tank. Allow the Quadris Xtra to completely
disperse. Spray the mixture with the agitator running.
Observe the most restrictive of the labeling limitations and precautions of all products
used in tank mixtures.
SPRAY DRIFT MANAGEMENT
SPRAY DRIFT MANAGEMENT
Aerial Applications
x 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.
x Applicators are required to select nozzles that deliver medium to coarse spray
droplets in accordance with ASABE Standard S-572.1.
x 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.
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
Quadris Xtra
Page 11
x User must only apply with the release height recommended by the manufacturer, 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 S-572.1).
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
x THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY
DRIFT.
x BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL
CONDITIONS.
IMPORTANCE OF DROPLET SIZE
The 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 – Groundboom
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 higher flow rate.
x Pressure - Use the lowest spray pressure recommended for the nozzle to
produce the target spray volume and droplet size.
x Nozzle Type - Use a spray nozzle that is designed for the intended 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.
BOOM HEIGHT – Groundboom
x For ground equipment, the boom should remain level with the crop and have
minimal bounce.
RELEASE HEIGHT – Aircraft
x Higher release heights increase the potential for spray drift.
SHIELDED SPRAYERS
Quadris Xtra
Page 12
x 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
x When making applications in hot and dry conditions, set up equipment to
produce larger droplets to reduce effects of evaporation.
TEMPERATURE INVERSIONS
x 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. Their 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
x Drift potential increases at wind speeds. AVOID APPLICATIONS DURING
GUSTY WIND CONDITIONS.
x Applicator need to be familiar with local wind patterns and terrain that could affect
spray drift.
APPLICATION INSTRUCTIONS
Apply Quadris Xtra at rates and timings as described in this label. Quadris Xtra may be
applied by ground, by air, or via chemigation. Refer to crop section for specific directions.
Apply Quadris Xtra in a minimum of 10 GPA via ground application equipment and 2 GPA
via aerial application equipment.
Directions for Use Through Sprinkler Chem igation Systems (apply Quadris Xtra
only to crops for which chemigation is specified on this label):
Spray Preparation: Chemical tank and injector system should be thoroughly cleaned.
Flush system with clean water.
Use Precautions for Sprinkler Irrigation Applications
Apply this product through sprinkler irrigation systems including center pivot, lateral move,
end tow, side [wheel] roll, traveler, big gun, solid set, drip (trickle), or hand move irrigation
Quadris Xtra
Page 13
systems. Do not apply this product through any other type of irrigation system except as
specified on this label.
Apply with center pivot or continuous-move equipment distributing 1/2 acre-inch or less
during treatment. In general, use the least amount of water required for proper distribution
and coverage. If stationary systems (solid set, handlines or wh eel lines other than
continuous-move) are used, this product should be injected into no more than the last 20-
30 minutes of the set. Do not apply when winds are greater than 10-15 mph to avoid drift
or wind skips. Do not apply when wind speed favors drift beyond the area intended for
treatment. Plant injury, lack of effectiveness, or illegal pesticide residues in the crop can
result from non-uniform treated water. Thorough coverage of foliage is required for good
control. Good agitation should be maintained during the entire application period.
If you have questions about calibration you should contact State Extension Service
specialist, equipment manufacturers or other experts.
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.
The pesticide injection pipeline must contain a functional, automatic, quick-closing check
valve to prevent the flow of fluid back toward the injection pump.
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 bein g withdrawn from the supply tank when the
irrigation system is either automatically or manually shut down.
The system must contain functional interlocki ng controls to automatically shut off the
pesticide injection pump when the water pump motor stops.
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.
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.
Allow sufficient time for pesticide to be flushed through all lines and all nozzles before
turning off irrigation water. A person k nowledgeable 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.
Quadris Xtra

Do not connect an irrigation system (incl uding 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.
Specific Instructions for Public Water Systems
1. Public water system means a system for the provision to the public of piped water
for human consumption if such system ha s at least 15 service connections or
regularly serves an average of at least 25 individuals daily at least 60 days out of
the year.
2. Chemigation systems connected to public water systems must contain a functional,
reduced-pressure zone (RPZ), back-flow preventer or the functional equivalent in
the water supply line upstream from the point of pesticide introduction. As an
option to the RPZ, the water from the public water system should be discharged
into a reservoir tank prior to pesticide introduction. There shall be a complete
physical break (air gap) between the outlet end of the fill pipe and the top or
overflow rim of the reservoir tank of at least twice the inside diameter of the fill
pipe.
3. The pesticide injection pipeline must contain a functional, automatic, quick-closing
check valve to prevent the flow of fluid back toward the injection pump.
4. The pesticide injection pipeline must 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.
5. The system must contain functional interlocking controls to automatically shut off the
pesticide injection pump when the water pump motor stops or in cases where there
is no water pump, 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 for treatment.

5–6.8 Apply Quadris Xtra between Feekes Stage 8 and
10.5.1. Protecting the flag leaf is important for
maximizing the potential yield.
The minimum retreatment interval is 14 days.
Quadris Xtra may be applied up to 30 days prior to
harvest. Quadris Xtra may be applied by ground, air
or chemigation.
Resistance Management: No more than two foliar
applications of Quadris Xtra or other strobilurin
fungicides should be made per growing season. Do
not alternate or tank mix with fungicides to which
resistance has developed in the pathogen population.
Specific Use Restrictions:
(1) Do not apply more than 6.8 fl. oz./A of Quadris Xtra (0.036 lb. a.i./A cyproconazole and 0.089 lb. a.i./A
azoxystrobin) per year.
(2) Do not apply more than 6.8 fl. oz/A (0.036 lb. a.i./A cyproconazole and 0.089 lb. a.i./A azoxystrobin) per single
application.
(2) Do not harvest wheat within 30 days of application.
(3) Do not harvest forage or hay within 21 days of application.
(4) Do not apply more than 0.036 lb. a.i./A/year cyproconazole containing products.
(5) Do not apply more than 0.4 lb. a.i./A/year azoxystrobin containing products.

3.5–6.8 Apply Quadris Xtra when disease first appears. Use
the low rate when disease pressure is low. Under
heavy disease pressure or if conditions are favorable
for disease, apply the high rate. A second application
may be made 7–14 days later. A maximum of 6.8
oz./A per season may be used.
Application Directions: Apply no more than 2
applications of Quadris Xtra or any other Group 11
fungicide per year. Quadris Xtra may be applied by
ground, air or chemigation.
Resistance Management: No more than two foliar
applications of Quadris Xtra or other strobilurin
fungicides should be made per growing season. Do
not alternate or tank mix with fungicides to which
resistance has developed in the pathogen population.
Specific Use Restrictions:
(1) Do not apply within 30 days of harvest.
(2) Do not harvest silage within 21 days of an application.

Remarks
Soybean Application Directions: Coverage and penetration
are important for best results. Use sufficient water
volume to provide thorough and uniform plant
coverage. Applications may be made by ground, air
or chemigation. Addition of an additive with
spreading and penetrating qualities will enhance
coverage and efficacy.
Resistance Management: No more than two foliar
applications of Quadris Xtra or other strobilurin
fungicides should be made per growing season. Do
not alternate or tank mix with fungicides to which
resistance has developed in the pathogen population.
Rust
(Phakopsora spp.)
4.0–6.8
For soybean rust: Apply 4–6.8 fl. oz./A. Repeat at
14-28 day interval, if conditions persist for rust
development. Lower use rates may require a shorter
spray interval. Depending on the conditions,
application timing should be at R1 (beginning
flowering, approximately 50 days after planting) up to
the R6 stage (seed development), but could be
earlier.

5.0–6.8 For diseases other than soybean rust: Begin
Quadris Xtra applications prior to disease
development. Use the higher rates under conditions
favorable for severe disease pressure, dense plant
canopies, or when disease is present. Contact
extension personnel for local economic thresholds
and timings for specific diseases in your area. An
adjuvant may be added at recommended rates to
improve coverage.
