Environmental Hazards

This pesticide is toxic to fish, aquatic invertebrates, oysters, and shrimp. For terrestrial
uses: DO NOT apply directly to water, 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

This chemical has properties and characteristics associated with chemicals detected in
groundwater. This chemical may leach into groundwater if used in areas where soils
are permeable, particularly where the water table is shallow.

Switch 62.5WG
Page 4

Surface Water Advisory

This chemical may contaminate water through drift of spray in wind. This chemical has
a high potential for runoff for several months or more after application. Poorly draining
soils and soils with shallow water tables are more prone to produce runoff that contains
this chemical. A level, well-maintained vegetative buffer strip between areas to which
this chemical is applied and surface water features including ponds, streams, and
springs will reduce the potential for contamination of water from rainfall runoff. Runoff of
this chemical will be reduced by avoiding applications when conditions favor runoff (for
example when soils are saturated and/or significant rainfall is forecast in the next 48
hours). Sound erosion control practices will reduce this chemical’s contribution to
surface water contamination.

Physical or Chemical Hazards

DO NOT use or store near heat or open flame.

RESISTANCE MANAGEMENT


For resistance management, please note that Switch 62.5WG contains both a Group 9 /
cyprodinil and Group 12 / fludioxonil fungicide. Any fungal population may contain
individuals naturally resistant to either or both of the active ingredients in Switch
62.5WG and other Group 9 or Group 12 fungicides. A gradual or total loss of pest
control may occur over time if these fungicides 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 Switch 62.5WG or other Group 9 and Group 12 fungicides within a
growing season sequence with different groups that control the same pathogens.
 Use tank mixtures with fungi cides 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 diseas e 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 populati ons for resistance development.
 Contact your local extension specialist or certified crop advisor for any additional
pesticide resistance-management and/or IPM directions for specific crops and
pathogens.
 For further information or to report suspected resistance, contact Syngenta Crop
Protection at 1-866-796-4368. You can also contact university extension specialist to
report resistance.


APPLICATION INSTRUCTIONS

Thorough coverage is necessary to provide good disease control. Applications using
sufficient water volume to provide thorough and uniform coverage provide the most
effective disease control. Use minimum ground spray volumes of 10 gal/A for field and
vegetable crops and 50 gal/A for tree crops. For the crops to which aerial applications
are allowed, refer to the specific crop directions for use and the spray drift management
section.

Switch 62.5WG
Page 9
To avoid spray drift, DO NOT apply when conditions favor drift beyond the target area.
Avoid spray overlap, as crop injury may occur.

Equip sprayers with nozzles that provide accurate and uniform application. Calibrate
sprayer before use.

Use a pump with capacity to maintain the correct rated pressure for the nozzles
selected. Maintain sufficient agitation to keep the mixture in suspension. Use a jet
agitator, liquid sparge tube, or mechanical paddle for agitation. DO NOT air sparge.

Use screens to prevent nozzles from clogging. Use 50-mesh or coarser screens placed
after the tank and before the nozzles. Check nozzle manufacturers’ specifications.

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 agricultural experiment station.

OBSERVE THE FOLLOWING RESTRICTIONS WHEN SPRAYING IN THE VICINITY
OF AQUATIC AREAS INCLUDING LAKES, RESERVOIRS, RIVERS, PERMANENT
STREAMS, MARSHES OR NATURAL PONDS, ESTUARIES, AND COMMERCIAL
FISH FARM PONDS:

 DO NOT apply within 75 ft of bodies of water including lakes, reservoirs, rivers,
permanent streams, natural ponds, marshes, or estuaries.

 Shut off the sprayer when at row ends.

 DO NOT cultivate within 10 ft of aquatic areas as to allow a vegetative filter strip.

 Follow spray drift management instructions indicated below.


 For perennial crops including tree crops and grapes:
o For all plantings within 150 ft of bodies of water as described above, spray crops
from outside the planting away from the bodies of water.
o Spray last three rows windward of aquatic areas using nozzles on one side only,
with spray directed away from aquatic areas. Adjust or turn off top nozzles on the
side away from the grove/orchard when spraying the outside row. Shut off
nozzles when turning at ends of row or passing tree gaps in the rows.

Ground Application
 Apply in a minimum of 10 gallons of wa ter per acre, unless specified otherwise.

Switch 62.5WG
Page 10
Aerial Spray Directions

Avoid applications under conditions when uniform coverage cannot be obtained or when
excessive drift may occur.


Observe the following restrictions when spraying in the vicinity of aquatic areas
including lakes, reservoirs, rivers, permanent streams, marshes or natural ponds,
estuaries and commercial fish ponds:

 Use only on crops where aerial applications are indicated.

 DO NOT apply by air within 150 ft of lakes, reservoirs, rivers, permanent streams,
marshes or natural ponds, estuaries and commercial fish ponds.


 DO NOT apply when weather conditions favor drift to aquatic areas.

 DO NOT apply during a temperature inversion. Mist or fog may indicate the
presence of an inversion in humid areas.


Aerial Spray Precautions

Observe the following precautions when spraying in the vicinity of aquatic areas
including lakes, reservoirs, rivers, permanent streams, marshes or natural ponds,
estuaries and commercial fish ponds:

 Use the largest droplet size consistent with good pest control.

 Formation of very small droplets may be mi nimized by appropriate nozzle selection,
by orientating nozzles away from the air stream as much as possible, and by
avoiding excessive spray boom pressure.

 Reduce risk of exposure to aquatic areas by avoiding applications when wind
direction is toward the aquatic area.

 Low humidity and high temperatures increase the evaporation rate of spray droplets,
and therefore the likelihood of increased spray drift to aquatic area. Avoid spraying
during conditions of low humidity and/or high temperatures.

 For the crops to which aerial applications are allowed, refer to the specific crop
directions for use and the spray drift management section.

 Apply in a minimum of 5 gallons of wa ter per acre, unless specified otherwise.

SPRAY DRIFT MANAGEMENT


MANDATORY SPRAY DRIFT

Aerial Applications

 DO NOT release spray at a height greater than 10 ft above the vegetative canopy
unless a greater application height is necessary for pilot safety.
 For all applicators, applicat ors are required to use a medium or coarse spray
droplets size (ASABE S572.1).
 For aerial applications: 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 displace ment upwind at the downwind edge of the
field.
 Nozzles must be oriented so the spray is directed toward the back of the aircraft.
 DO NOT apply during temperature inversions.

Groundboom Applications

 Apply with the nozzle height specified by the manufacturer, but no more than 3 feet
above the ground or crop canopy.
 For all applications, applicators are requi red to use a medium or coarser spray
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 FO R AVOIDING OFF-SITE SPRAY DRIFT.
 BE AWARE OF NEARBY NON-TARG ET 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.

Switch 62.5WG
Page 12
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 directed 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.

Boom Height – Ground Boom
 For ground equipment, the boom must remain level with the crop and have minimal
bounce.

Controlling Droplet Size – Aircraft
 Adjust Nozzles – Follow nozzle manufacture r’s directions for setting up nozzles. To
reduce fine droplets, orient nozzles parallel with the airflow in flight.

Release Height – Aircraft
 Higher release heights increase the potential for spray drift.


Shielded Sprayers
 Shielding the boom or indi vidual 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 condi tions, 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.

Switch 62.5WG
Page 13
Wind
 Drift potential increases with wind speed. AVOID APPLICATIONS DURING GUSTY
WIND CONDITIONS.
 Applicators need to be familiar with local wi nd patterns and terrain that could affect
spray drift.

Boom-less 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.


Application Through Irrigation Systems (Chemigation)

 Use only on crops for which chemi gation is specified on this label.

 Apply this product only through drip, microj et, center pivot, solid set, hand move, and
moving wheel irrigation systems. DO NOT apply this product through any other type
of irrigation system.

 Crop injury, lack of effectiveness, or illega l pesticide residues in the crop can result
from non-uniform distribution of treated water.

 Apply in 0.125-0.25 inches/A of water. Excessive water may reduce efficacy.

 If you have questions about calibration, cont act 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 chemi gation system and responsible for its
operation, or under the supervision of the responsible person, shall shut the system
down and make necessary adjustments if the need arises.

Operating Instructions

1. The system must contain a functional ch eck-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 al so 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 interl ocking 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, for example 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.

Center Pivot Irrigation Equipment

Restrictions: (1) Use only with drive systems which provide uniform water distribution.
(2) DO NOT use end guns when chemigating Switch 62.5WG through center pivot
systems because of non-uniform application.

 Determine the size of the area to be treated.

 Determine the time required to apply ⅛-½ inch of water over the area to be treated
when the system and injection equipment are operated at normal pressures as
directed by the equipment manufacturer. When applying Switch 62.5WG 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 injecti on pump output when operated at normal line
pressure.

 Determine the amount of Switch 62.5WG requi red to treat the area covered by the
irrigation system.

 Add the required amount of Switch 62.5WG and sufficient water to meet the injection
time requirements to the solution tank.

 Make sure the system is fully charged wit h water before starting injection of the
Switch 62.5WG 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 t he Switch 62.5WG solution has cleared the
sprinkler head.

Solid Set, Hand Move, and Moving Wheel Irrigation Equipment

 Determine the acreage covered by the sprinklers.

 Fill injector solution tank with water and adj ust flow rate to use the contents over a
20- to 30-minute interval. When applying Switch 62.5WG through irrigation
equipment, use the lowest obtainable water volume while maintaining uniform
distribution.

 Determine the amount of Switch 62.5WG requi red to treat the area covered by the
irrigation system.

Switch 62.5WG

 Add the required amount of Switch 62.5WG 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 afte r treatment is completed. Continue to operate the
system until the Switch 62.5WG solution has cleared the last sprinkler head.


Drip or Microjet Chemigation Systems

Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from
non-uniform distribution of treated water.

Spray Preparation: Chemical tank and injector system must be thoroughly cleaned.
Flush system with clean water.

Use Directions for Drip or Microjet Irrigation Applications

Drip or Microjet Irrigation: Switch 62.5WG may be applied through drip irrigation
systems for soil-borne disease control. The soil must have adequate moisture capacity
prior to drip application.

 Terminate drip irrigation at fungicide deple tion from the main feed supply tank or
after 6 hours from start, whichever is shorter. For maximum efficacy, delay
subsequent irrigation (water only) for at least for 24 hours following drip application.

 The system must contain a functional che ck 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 c ontain a functional, automatic, quick-closing
check valve to prevent the flow of fluid back toward the injection pump.

 The pesticide injection pipeline must al so 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.

 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 incl ude 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.

Switch 62.5WG
Page 17

 Systems must use a metering pump, for ex ample 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 fo r 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 the supervision of the responsible
person, shall shut the system down and make necessary adjustments if the need
arises.

 If you have questions about calibration, cont act 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.


SPECIFIC INSTRUCTIONS FOR PUBLIC WATER SYSTEMS

1. Public water system means a system fo r 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 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, discharge the water from the public water
system 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 interl ocking controls to automatically shut off
the pesticide injection pump when the water pump motor stops, or in cases

Switch 62.5WG
Page 18
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
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.


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.

Switch 62.5WG Alone: Add ½ of the required amount of water to the mix tank. With
the agitator running, add the Switch 62.5WG to the tank. Continue agitation while
adding the remainder of the water. Begin application of the solution after the Switch
62.5WG has completely dispersed into the mix water. Maintain agitation until all of the
mixture has been applied.

Switch 62.5WG + Tank Mixtures: Switch 62.5WG is compatible in tank mixtures with
many commonly used fungicides, liquid fertilizers, herbicides, insecticides, and
biological control products. If tank mixes are desired, observe all directions,
precautions, and limitations on labeling of all products used. Consult compatibility
charts or your local or state agricultural authorities for compatibility information.

To prepare spray solution, add ½ of the required amount of water to the mix tank. Start
the agitator running before adding any tank mix partners. Add tank mix partners in this
order: products packaged in water-soluble packaging, wettable powders, wettable
granules (dry flowables) including Switch 62.5WG, liquid flowables, liquids, and
emulsifiable concentrates. Always allow each tank mix partner to become fully
dispersed before adding the next product. Provide sufficient agitation while adding the
remainder of the water. Maintain agitation until all of the mixture has been applied.

When using Switch 62.5WG in tank mixtures, add all products in water-soluble
packaging to the tank before any other tank mix partner, including Switch 62.5WG.
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.

Switch 62.5WG
Page 19
If using Switch 62.5WG in a tank mixture, observe all directions for use, crops/sites, use
rates, dilution ratios, precautions, and limitations which appear on the tank mix product
label. DO NOT exceed label dosage rates, and follow the most restrictive label
precautions and limitations. 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
registered.

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.
