Surface Water Advisory
This product may impact surface water quality due to run -
off of rain water . This product is classified as having a high
potential for reaching surface water via runoff for several
months or more after application . Poorly draining soils or
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 including ponds,
streams, and springs will reduce the potential for contami -
nation of water from rainfall runoff . Runoff of this product
will be reduced by avoiding applications when rainfall is
forecast to occur within 48 hours .

Product Information
SphaerexTM fungicide is a broad-spectrum fungicide
containing the active ingredients metconazole and
prothioconazole for use in wheat, barley, oats, rye, and
triticale . For optimum disease control, apply Sphaerex in
a regularly scheduled protective spray program and use in
a rotation program with non-Group 3 fungicides .
Mode of Action
Metconazole and prothioconazole, the active ingredients in
Sphaerex, inhibit the demethylation step of sterol biosyn-
thesis (DMI), which disrupts cell membrane synthesis and
are classified by the Fungicide Resistance Action Commit -
tee (FRAC) as Group 3 fungicides .
Resistance Management
Sphaerex contains Group 3 fungicides . Any fungal
population may contain individuals naturally resistant to
Sphaerex and other Group 3 fungicides . A gradual or
total loss of pest control may occur over time if these fun-
gicides are used repeatedly in the same fields . Follow
appropriate resistance management strategies .
To delay fungicide resistance, take one or more of
the following steps:
• Rotate the use of Sphaerex or other Group 3 fungi-
cides within a growing season sequence with different
groups that control the same pathogens .
• 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 .
• Adopt an integrated disease management program for
fungicide use that includes scouting, uses historical infor-
mation related to pesticide use, and crop rotation, and
which considers host plant resistance, impact of environ -
mental 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 treatment area for lack of biological efficacy that
might indicate possible resistance development .
• Contact your local extension specialist or certified crop
advisor for any additional pesticide resistance-
management and/or Integrated Pest Management
(IPM) guidance for specific crops and pathogens .
• For further information or to report suspected resistance,
consult your local BASF representative, extension spe -
cialist, or certified crop advisor .

Ground Application
Thorough coverage of foliage and flowers is required for opti-
mum disease control . A nonionic surfactant at the lowest
labeled rate may be used to improve spray coverage . Refer to
the adjuvant product label for specific use directions .
DO NOT use adjuvants that contain methylated seed oil,
crop oil concentrate, or crop oil with emulsifier properties .
Aerial Application
Select spray nozzles, pumping pressure, and sprayer height
to provide medium-to-fine spray droplets that penetrate
throughout the crop canopy . Spray calibration must be con-
ducted to confirm spray droplet sizes . Continue to monitor
spray application (including weather conditions) to assure
proper droplet size and canopy penetration . For all aerial
application volumes (gpa), a nonionic surfac tant at the lowest
labeled rate may be used to improve spray coverage . Refer to
the adjuvant product label for specific use directions .
DO NOT use adjuvants that contain methylated seed oil,
crop oil concentrate, or crop oil with emulsifier properties .
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 drop-
lets . 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 recommend-
ed 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’ recom-
mendations 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 .
Boomless Ground Applications: Setting nozzles at the
lowest effective height will help to reduce the potential for
spray drift
Handheld Technology Applications: Take precautions
to minimize spray drift .
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 . Tempera-
ture 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 . Appli-
cators need to be familiar with local wind patterns and
terrain that could affect spray drift .
Field Sprinkler Irrigation (Chemigation)
Application
• Apply this product only through sprinkler irrigation sys -
tems including center pivot, lateral move, end tow, side
(wheel) roll, traveler, big gun, solid set, or hand move
6
{Note to PM: Italicized text enclosed in “{ }” is information for the reviewer and not part of the label.
[Bracketed information is optional text.] Text within brackets and separated by “/” denotes and/or options.}
irrigation systems . DO NOT apply this product through
any other type of irrigation system .
• Add this product to the pesticide supply tank containing
sufficient water to maintain a continuous flow by the injec-
tion equipment . In continuous moving systems, inject this
product-water mixture continuously, applying the labeled
rate per acre for that crop . DO NOT apply more than
1/2 inch (13,577 gallons) per acre . In stationary or
non-continuous moving systems, inject the product-water
mixture in the last 15 to 30 minutes of each set, allowing
enough time to apply the labeled rate per acre through the
sprinkler heads . Crop injury, lack of effectiveness, or illegal
pesticide residues in the crop can result from nonuniform
distribution of treated water . Thorough coverage of foliage
and flowers is required for optimum disease control . Main-
tain constant agitation throughout mixing and application .
• If you have questions about calibration, contact state
extension service specialists, equipment manufacturers,
or other experts .
• The system must contain a functional check valve, vacu -
um 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 func -
tional, 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 with-
drawn from the supply tank when the irrigation system is
either automatically or manually shut down .
• The system must contain functional interlocking controls
to automatically shut off the pesticide injection pump
when the water pump motor stops .
• The irrigation line or water pump must include a function -
al 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, for example, a pos-
itive 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 knowledgeable of the chemigation system and
responsible for its operation or under supervision of the
responsible person, shall shut the system down and
make necessary adjustments if needed .
• DO NOT connect an irrigation system 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 has 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 sys-
tems must contain a functional, reduced-pressure zone,
backflow preventer (RPZ) or the functional equivalent in
the water supply line upstream from the point of pesti-
cide introduction . As an option to the RPZ, the water
from the public water system must be discharged into a
reservoir tank prior to pesticide introduction . There shall
be a complete physical break (air gap) between the out-
let 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 function -
al, automatic, quick-closing check valve to prevent the
flow of fluid back toward the injection pump .
4 . The pesticide injection pipeline must contain a function -
al, 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 with-
drawn 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, for example, a
positive displacement injection pump (e .g ., diaphragm
pump), effectively designed and constructed of materi-
als that are compatible with pesticides and capable of
being fitted with a system interlock .
Tank Mixing Other Products and Additives
It is the pesticide user’s responsibility to ensure that all prod-
ucts 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 precaution-
ary statements of each product in the tank mixture .
SphaerexTM fungicide can be tank mixed with other
fungicides, insecticides, herbicides, liquid fertilizers, biolog -
ical control products, adjuvants, and additives . Always
follow the most restrictive label use directions . See
Table 1. Detailed Use Directions for additional
information .
BASF has not tested all varieties and cultivars with all pos-

Application Directions
- Under certain environmental conditions, when SphaerexTM fungicide is applied with emulsifiable concentrate (EC)
formulated herbicides, bromoxynil contain products, insecticides, and/or fertilizers, phytotoxicity can occur . The pos-
sibility of phytotoxicity increases if applications are made under cool, wet, cloudy conditions that persist for several
days following application . Lower gpa applications can increase the risk of phytotoxicity .
- Livestock may graze treated fields .
Foliar Applications
- When conditions favor disease or disease pressure is high, use the higher specified rate . For aerial applications,
apply in a minimum of 2 gallons per acre (gpa) total spray volume . For ground applications, apply a minimum of
5 gpa .
- Early Season: Apply when conditions favor disease development or disease pressure is high prior to flag leaf emer -
gence . When an early season application is used, a second application may be required to protect the flag leaf . Early
season applications will not suppress or control head scab .
- Flag Leaf: To maximize yield, it is important to protect the flag leaf . For optimal disease control, begin applications
prior to disease development or immediately after flag leaf emergence .
Head Scab Applications
- For best results, apply during early flowering using forward and reverse facing nozzles to ensure thorough coverage
of the heads . For aerial applications, apply in a mini mum of 2 gpa total spray volume . For ground applications, apply
a minimum of 10 gpa .
