PRECAUTIONARY STATEMENTS
HAZARDS TO HUMANS AND DOMESTIC ANIMALS
CAUTION
Harmful if swallowed. Wash thoroughly with soap and water after handling and before
eating, drinking, chewing gum, using tobacco or using the toilet.
Human flagging is prohibited.
PERSONAL PROTECTIVE EQUIPMENT (PPE)
Applicators and other handlers must wear –
• Long-sleeved shirt and long pants
• Chemical-resistant gloves made of barrier laminate, butyl rubber, nitrile rubber,
neoprene rubber, natural rubber, polyethylene, polyvinyl chloride, or viton.
• Shoes plus socks
USER SAFETY REQUIREMENTS
Follow manufacturer's instructions for cleaning/maintaining personal protective
equipment (PPE). If no such instructions for washables exist, use detergent and
hot water. Keep and wash PPE separately from other laundry.
ENGINEERING CONTROLS
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 170.240 (d) (4-6)], the handler PPE requirements may be
reduced or modified as specified in the WPS.
ENVIRONMENTAL HAZARDS
Bixafen and azoxystrobin is toxic to fish and aquatic invertebrates. Both chemicals 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 washwater or rinsate.
USER SAFETY RECOMMENDATIONS
Users should:
x Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and
put on clean clothing.
x Remove PPE immediately after handling this product. Wash the outside of gloves
before removing. As soon as possible, wash thoroughly and change into clean
clothin
g.
Ground Water Advisory
Bixafen has properties and characteristics associated with chemicals detected in
groundwater.
Azoxystrobin and a degradate of azoxystrobin is 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.
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 high potential for reaching aquatic sediment 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 these
chemicals 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.
Sound erosion control practices will reduce this product’s potential to reach aquatic
sediment via runoff.
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in any manner inconsistent with
its labeling. Read entire label before using this product.
Do not apply this product in a way that will contact workers or other persons, either
directly or indirectly or through drift. Only protected handlers may be in the area during
application. For any requirements specific to your State or Tribe, consult the agency
responsible for pesticide regulation.
[Optional state restriction language for the state of NY: Not for sale, distribution, or use
in -- Counties of New York State.]
FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONARY
STATEMENTS ON THIS LABEL MAY RESULT IN POOR DISEASE CONTROL, CROP
INJURY AND/OR ILLEGAL RESIDUES.
RESISTANCE MANAGEMENT
For resistance management, please note that F9653-1 contains both a Group 7 (Bixafen) and
Group 11 (Azoxystrobin) fungicide. Any fungal population may contain individuals naturally
resistant to F9653-1 and other Groups 7 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 must be followed.
To delay fungicide resistance, take one or more of the following steps:
x 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.
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 your pesticide
distributor or university extension specialist.

SPRAY DRIFT
Aerial Applications:
• Do not release spray at a height greater than 10 ft. above the ground or crop canopy, unless a
• greater application height is necessary for pilot safety.
• Applicators are required to select nozzles that deliver Medium to coarse spray droplets in
• accordance with ASABE Standard S-572.1.
• 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
• Applicators must use ½ swath displacement upwind at the downwind edge of the field.
• Do not apply during temperature inversions.
Groundboom Applications:
• User must only apply with the release 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 S572.1).
• 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.
ATTENTION
F9653-1 Fungicide is extremely phytotoxic to certain apple varieties.
AVOID SPRAY DRIFT. Extreme care must be used to prevent injury to apple trees (and apple
fruit).
DO NOT spray F9653-1 Fungicide where spray drift may reach apple trees.
DO NOT spray when conditions favor drift beyond area intended for application.
Conditions which may contribute to drift include thermal inversion, wind speed and direction,
sprayer nozzle/pressure combinations, spray droplet size, etc. Contact your State extension
agent for spray drift prevention guidelines in your area.
DO NOT use spray equipment which has been previously used to apply F9653-1 Fungicide 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.
APPLICATION AND CALIBRATION TECHNIQUES FOR CHEMIGATION
Apply this product only through center pivot, motorized lateral move, traveling gun, solid set
and portable (wheel move, side roll, end tow, or hand move) irrigation system(s). Do not apply
this product through any other type of irrigation system. Crop injury, lack of effectiveness, or
illegal pesticide residues in the crop can result from non-uniform distribution of treated water. If
you have questions about calibration, you must contact State Extension Service specialists,
equipment manufacturers or other experts. Do not apply this product through irrigation systems
connected to a public water system. “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 per
year. Controls for both irrigation water and pesticide injection systems must be functionally
interlocked, to automatically terminate pesticide injection when the irrigation water pump motor
stops. A person knowledgeable of the irrigation system and responsible for its operation shall
be present to discontinue pesticide injection and make necessary adjustments, should the
need arise.
The irrigation water pipeline must be fitted with a functional, automatic, quick-closing check
valve to prevent the flow of treated irrigation water back toward the water source. The pipeline
must also be fitted with a vacuum relief valve and low pressure drain, located between the
irrigation water pump and the check valve, to prevent back-siphoning of treated irrigation water
into the water source. Always inject F9653-1 Fungicide into irrigation water after it discharges
from the irrigation pump and after it passes through the check valve. Never inject pesticides
into the intake line on the suction side of the pump. Pesticide injection equipment must be
fitted with a functional, normally closed, solenoid- operated valve located on the intake side of
the injection pump. Interlock this valve to the power system, to prevent fluid from being
withdrawn from the chemical supply tank when the irrigation system is either automatically or
manually turned off.
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 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. Spray
mixture in the chemical supply tank must be agitated always, otherwise settling and uneven
application may occur. Do not apply when wind speed favors drift beyond the area intended for
treatment. 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.
F9653-1 Fungicide may be used through two basic types of sprinkler irrigation systems as
outlined in Sections A and B below. Determine which type of system is in place, then refer to
the appropriate directions provided for each type.
A. Center Pivot, Motorized Lateral Move and Traveling Gun Irrigation Equipment
For injection of pesticides, these continuously moving systems must use a positive
displacement injection pump, of either diaphragm or piston type, constructed of materials that
are compatible with pesticides and capable of being fitted with a system interlock and capable
of injection at pressures approximately 2-3 times those encountered within the irrigation water
line. Venturi applicator units cannot be used on these systems. Thoroughly mix specified
amount of F9653-1 Fungicide for acreage to be covered into same amount of water used
during calibration and inject into system continuously for one revolution or run. Mixture in the
chemical supply tank must be continuously agitated during the injection run. Shut off injection
equipment after one revolution or run, but continue to operate irrigation system until F9653-1
Fungicide has been cleared from last sprinkler head.
B. Solid Set and Portable (Wheel Move, Side Roll, End Tow, or Hand Move) Irrigation
Equipment
With stationary systems, an effectively designed in-line venturi applicator unit is preferred
which is constructed of materials that are compatible with pesticides; however, a positive-
displacement pump can also be used. Determine acreage covered by sprinkler. Fill tank of
injection equipment with water and adjust flow to use contents over a thirty to forty-five-minute
period. Mix desired amount of F9653-1 Fungicide for acreage to be covered with water so that
the total mixture of F9653-1 Fungicide plus water in the injection tank is equal to the quantity of
water used during calibration and operate entire system at normal pressures recommended by
the manufacturer of injection equipment used, for amount of time established during calibration.
Mixture in the chemical supply tank must be continuously agitated during the
injection run. F9653-1 Fungicide can be injected at the beginning or end of the irrigation cycle
or as a separate application. Stop injection equipment after treatment is completed and
continue to operate irrigation system until F9653-1 Fungicide has been cleared from last
sprinkler head.
MIXING INSTRUCTIONS
Ensure the sprayer tank, filter and lines are clean, then partially fill the spray tank with clean
water. Measure the required amount of F9653-1 Fungicide and pre-mix with a small volume of
water, add this to the tank.
Agitate to ensure thorough mixing while filling tank with remaining water. Maintain agitation
during application and apply with properly calibrated application equipment. Do not allow spray
mixture to stand overnight or for prolonged periods, as some chemical breakdown may occur,
particularly in water with a high pH. The spray solution must be buffered to a pH of 5.0 - 7.0. A
high quality, nonionic spreader can be used as a spray tank additive for every application.
F9653-1 Fungicide must be added to the tank before the addition of any adjuvant. Consult the
adjuvant label or manufacturer for crop tolerance and safety information when used with
F9653-1 Fungicide.
APPLICATION TIMING
F9653-1 Fungicide can be used in a preventive spray program to manage diseases in labeled
crops. Complementary dual modes of action provided by F9653-1 Fungicide helps prevent the
development of disease resistance. It is directed that this product be used within an Integrated
Pest Management Program (IPM), rotating with non FRAC 11 or FRAC 7 fungicides. Carefully
read, and understand, and follow all directions and precautions. Disease pressure and
environmental conditions will determine application rates and the length of the spray intervals.
Consult local disease advisory system recommendations to determine the predicted disease
pressure and the associated application rates and intervals.
COMPATIBILITY
The tank mixing behavior of this fungicide with other pesticides has not been fully investigated.
If tank mixing with other pesticides is desirable, conduct a jar test with rates and volumes of
carrier typically used in an agricultural application. Look for signs of separation, globules,
sludge, flakes or other precipitates. DO NOT tank mix with the other pesticide if the jar test with
F9653-1 Fungicide has indicated incompatibility. Follow the most restrictive labeling on this
label or the tank mixture partner. Before adding F9653-1 Fungicide along with other additives
or pesticide products to a spray tank, a compatibility jar test must be conducted.
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.
Compatibility Jar Test:
F9653-1 Fungicide is compatible with most products, however not all have been tested. Use
the following compatibility test to ensure physical compatibility.
Using a quart jar, add the proportionate amounts of the products to approximately one quart of
water with agitation. Add wettable powders and water dispersible granular products first, next
liquid flowables, then emulsifiable concentrates, and last liquid soluble products. After thorough
mixing, allow this mixture to stand for 5 minutes. If the combination remains mixed or can be
readily remixed, it is physically compatible. Once compatibility has been proven, use the same
procedure for adding products to the spray tank. Use tank mix combinations on a small number
of plants before treating larger areas. When tank mixing, follow more restrictive
labeling of any tank mix partner. Do not tank mix with any product that contains a prohibition
on tank mixing.
Before applying any tank mixture not specifically directed on this label, the crop safety of the
target crop must be confirmed by applying the mixture to a small area of the target crop in
accordance to the label instructions.
FOLIAR APPLICATION
Maximum benefit of F9653-1 Fungicide from foliar applications requires coverage both outside
and inside the plant canopy. Thorough coverage of foliage is obtained by using proper spray
pressure, a minimum of 10 gallons per acre, appropriate nozzles that provide uniform spray
distribution and minimize drift, nozzle spacing and sprayer speed. Follow directions of nozzle
manufacturer for nozzle pressures.
SOILBORNE/SEEDLING DISEASE CONTROL
For those crops that have specific use directions for soil born disease control: F9653-1
Fungicide can provide control of many soil borne diseases if applied early in the growing
season. Specific applications for soil borne diseases include in-furrow applications and banded
applications applied over the row, either shortly after plant emergence or during herbicide
applications or cultivation. These applications will provide control of pre-or post- emergence
damping off and diseases that infect plants at the soil-plant interface. For specific application
instructions see the individual crop sections for application timings and spray intervals.
The use of either type of application depends on the cultural practices in the region. In some
locations, one type of application may provide better disease control than the other, depending
on the timing of the disease epidemic. Seedling diseases are generally controlled by in-furrow
applications while banded applications are more effective against soil borne diseases that
develop later in the season. Consult your local expert to get some guidance regarding
application type. Under cool, wet conditions, crop injury from soil directed applications can
occur.
BANDED:
Apply F9653-1 Fungicide prior to infection as a directed spray to the soil, using single or
multiple nozzles, adjusted to provide thorough coverage of the lower stems and the soil surface
surrounding the plants. Band width must be limited to 7 inches or less. Apply F9653-1
Fungicide at a rate of 0.40 fl. oz. product (0.20 oz. a.i.)/1000 row feet. For banded applications on
22-inch rows, the maximum application rate is 0.345 fl. oz./1000 row feet.
These applications come into contact with the foliage and are counted as foliar applications
when considering resistance management. They may be applied during cultivation or hilling
operations to provide soil incorporation.
IN-FURROW:
Apply F9653-1 Fungicide as an in-furrow spray in 3-15 gallons of water at planting. Mount the
spray nozzle so the spray is directed into the furrow just before the seeds are covered. Use the
higher rate when the weather conditions are expected to be conducive for disease
development, if the field has a history of Pythium problems, or if minimum/ low till programs are
in place.

Foliar disease: For ground, aerial
and/or chemigation, apply F9653-1 in
a protective spray schedule or when
weather conditions are favorable for
disease development. Repeat
applications at 7 to 14-day intervals.
When disease is high, use the higher
rate and shorter interval. Applications
are from the onset of disease up to
the R4 growth stage of corn.
For optimum control of foliar
diseases, a surfactant must be tank-
mixed with F9653- 1.
For management of fungal pathogen
resistance development, do not
make more than 2 sequential
applications per year before
alternating to another fungicide from
a FRAC group different from FRAC
groups 7 and 11.

Soil disease: For fields with
moderate infestation level, apply by
ground, aerial and/or chemigation,
two applications using the maximum
rate at number 2 and 4, of a 7
application preventive spray
schedule. For consecutive
applications, use a 14-day
application interval.
Apply as a 30-40 gal/A spray,
targeting the root and pod zone
with nozzles producing large
droplets to penetrate canopy.
For soil-borne diseases, rainfall or
irrigation will optimize activity of
