PRODUCT INFORMATION
Praiz Fungicide can be used effectively in dilute or concentrate spray s. Thorough, uniform coverage is
essential for disease control.
Resistance Management
For resistance management, Praiz Fungicide contains a Group M05 fungicide, chlorothalonil. Any fungal 
population may contain individuals naturally resistant to Praiz Fungicide and other Group M05 fungicides. A 
gradual or total loss of pest control may occur over time if th ese 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:
x Rotate the use of Praiz Fungicide or other Group M05 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 a re 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 us e that includes scouting, uses 
historical information related to pesticide use, and crop rotat ion, and which considers host plant 
resistance, impact of environmental conditions on disease devel opment, disease thresholds, as well as 
cultural, biological and other chemical control practices.

Page 4 of 23 
 
x Where possible, make use of predictive disease models to effect ively 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, certified crop advisor a n d / o r W i n f i e l d S o l u t i o n s , L L C 
representative for any additional pesticide resistance manageme nt and/or IPM recommendations for 
specific crops and pathogens.
x For further information or to report suspected resistance, cont act your Winfield Solutions, LLC 
representative.
Use Restrictions
x Do not use on greenhouse-grown crops.
x Do not apply this product within 150 feet for aerial applications, or 25 feet for ground
applications of marine/estuarine water bodies, unless there is an untrea ted buffer area of that
width between the area to be treated and the water body.
x Do not combine Praiz Fungicide with Bacillus thuringiensis-containi ng products (e.g. Dipel ®),
Latron B-1956 ® or Latron AG-98 ® as phytotoxicity may result from the combination when applied
to the crops on this label.
Use Precautions
x Do not combine Praiz Fungicide in spray tank with pesticides, adjuvants , surfactants or
fertilizers, unless your prior use has shown the combination physically compatible, effective and
noninjurious under your conditions of use. 
Spray Drift Management
Avoiding spray drift at the application site is the responsibility of the a pplicator. The interaction of many
equipment and weather- related factors determine the potential for spray drift. The applicator and the
grower are responsible for considering all these factors when making deci sions.
The following drift management requirements must be followed to avoid off target drift from aerial
applications to agricultural field crops. These requirements do not app ly to conifer applications.
1) The distance of the outer most nozzles on the boom must not exceed 3/4 the le ngth of the
wingspan or rotor.
2) Nozzles must always point backward parallel with the air stream and never be pointed
downwards more than 45 degrees.
Where states have more stringent regulations, they should be observed.
The applicator should be familiar with and take into account the informati on covered in the Aerial
Drift Reduction Advisory Information.
Aerial Drift Reduction Advisory Information
This section is advisory in nature and does not supersede the mandatory lab el requirements.
Information on Droplet Size
The most effective way to reduce drift potential is to apply large droplets . The best drift management
strategy is to apply the largest droplets that provide sufficient coverag e and control. Applying larger
droplets reduces drift potential but will not prevent drift if applicatio ns are made improperly, or under
unfavorable conditions (See Wind, Temperature and Humidity).
Controlling Droplet Size
• Volume - Use high flow rate nozzles to apply the highest practical spray volume. No zzles with
higher rated flows produce larger droplets.
• Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For many nozzle
types, lower pressure produces larger droplets. When higher flow rates are needed, use higher
flow rate nozzles instead of increasing pressure.
• Number of Nozzles - Use the minimum number of nozzles that provide uniform coverage.

Page 5 of 23 
 
• Nozzle Orientation - Orienting the nozzles so that the spray is released parallel to the airstr eam
produces larger droplets than other orientations and is the recommended practice. Significant
deflection from horizontal will reduce droplet size and increase drift potential.
• Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle
types, narrower spray angles produce larger droplets. Consider using low-drift nozzles. Solid
stream nozzles oriented straight back produce the largest droplets and the lowest drift potential .
Boom Length
For some use patterns, reducing the effective boom length to less than 3/ 4 of the wingspan or rotor
length may further reduce drift without reducing swath width.
Application Height
Applications should not be made at a height greater than 10 ft above the top of the largest plants,
unless a greater height is required for aircraft safety. Making applicat ions at the lowest height that is
safe reduces exposure of droplets to evaporation and wind.
SwathAdjustment
When applications are made with a crosswind, the swath will be displaced do wnwind. Therefore, on
the upwind and downwind edges of the field, the applicator must compensat e for this displacement by
adjusting the path of the aircraft upwind. Swath adjustment distance shou ld increase with increasing
drift potential (higher wind, smaller drops, etc.).
Wind
Drift potential is lowest between wind speeds of 2-10 mph. However, many f actors, including droplet
size and equipment type determine drift potential at any given speed. Appl ication should be avoided 
below 2 mph due to variable wind direction and high inversion p otential. NOTE: Local terrain can
influence wind patterns. Every applicator should be familiar with local wind patterns and how they
affect spray drift.
Temperature and Humidity
When making applications in low relative humidity, set up equipment to pro duce larger droplets to
compensate for evaporation. Droplet evaporation is most severe when co nditions are both hot and
dry.
Temperature Inversions
Applications should not occur during a temperature inversion because dri ft potential is high.
Temperature inversions restrict vertical air mixing, which causes smal l suspended droplets to remain
in a concentrated cloud. This cloud can move in unpredictable directions due to the light variable
winds common during inversions. Temperature inversions are characteriz ed by increasing
temperatures with altitude and are common on nights with limited cloud cov er and light to no wind.
They begin to form as the sun sets and often continue into the morning. Their presence can be
indicated by ground fog; however, if fog is not present, inversions can als o be identified by the
movement of smoke from a ground source or an aircraft smoke generator. S moke that layers and
moves laterally in a concentrated cloud (under low wind conditions) indic ates an inversion, while
smoke that moves upward and rapidly dissipates indicates good vertical ai r mixing.
Sensitive Areas
The pesticide should only be applied when the potential for dri ft to adjacent sensitive areas (e.g., 
residential areas, bodies of water, known habitat for threatene d or endangered species, non-target crops) 
is minimal (e.g., when wind is blowing away from the sensitive areas).

APPLICATION INSTRUCTIONS
Dosage rates on this label indicate pints of Praiz Fungicide per acre, un less otherwise stated. Under
conditions favoring disease development the high rate specified and shor test application interval should
be used.
Note: Slowly invert container several times to assure uniform mixture.
The required amount of Praiz Fungicide should be added slowly into the sp ray tank during filling. With
concentrate sprays, pre-mix the required amount of Praiz Fungicide in a clean container and add to the
spray tank as it is being filled. Keep agitator running when filling spr ay tank and during spray operations.
It is the pesticide user’s responsibility to ensure that all pr oducts used in tank mixtures are registered for 
the intended use. Read and follow the applicable restrictions a nd limitations and directions for use on all 
product labels involved in tank mixing. Users must follow the m ost restrictive directions for use and 
precautionary statements of each product in the tank mixture.
Apply Praiz Fungicide in sufficient water to obtain adequate coverage o f foliage. Gallonage to be used
will vary with crop and amount of plant growth.
For field and row crops, spray volume usually will range from 20 to 150 gall ons per acre for dilute sprays 
and 5 to 10 gallons per acre for concentrated ground sprays and aerial applications.
For tree and orchard crops, apply Praiz Fungicide in sufficient water a nd with proper calibration to obtain
uniform coverage of tree canopy. For fruit and nut bearing crops, the maximum volume is 300 gallons per
acre unless indicated otherwise in the specific use directions. For conifers, the maximum volume is 100
gallons per acre.
Application and Calibration Techniques for Chemigation
Apply this product only through center pivot, motorized lateral move, tra veling 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 c rop can result from non-uniform
distribution of treated water.
If you have questions about calibration, contact State Extension Servic e specialists, equipment
manufacturers or other experts.
Do not apply this product through irr igation systems connected to a publ ic water system. Public water
system means a system for the provisi on 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 b e functionally interlocked, so 
as to automatically terminate pesticide injection when the irrigation wa ter pump motor stops. A
person knowledgeable of the irrigation system and responsible for its operation shall be present so
as to discontinue pesticide injection and make necessary adjustments, sh ould 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 wat er into the water source.
Always inject Praiz 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.

Page 7 of 23 
 
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 val ve to the power system, so as
to prevent fluid from being withdrawn from the chemical supply tank when th e 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 switc h 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 at all times, o therwise 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 injectio n 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.
 
Praiz Fungicide may be used through two basic types of sprinkler irrigati on systems as outlined in
Sections A and B below. Determine which type of system is in place, then re fer to the appropriate
directions provided for each type.
A. Center Pivot, Motorized Lateral Move and Traveling Gun Irrigation Equi pment
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 cap able 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 the specified amount of Praiz Fungicide for acreage to be covered into same 
amount of water used during calibration and inject into system continuo usly 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 Praiz 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 effectiv ely designed in-line venturi applic ator 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 Praiz Fungicide for
acreage to be covered with water so that the total mixture of Praiz 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. Agitation is recommended. Praiz 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 Praiz Fungicide has been
cleared from last sprinkler head.

Tree and Orchard Crops
Apply Praiz Fungicide in sufficient water and with proper calib ration to obtain uniform coverage of tree 
canopy. For fruit and nut bearing crops, the maximum volume is 300 gallons per acre unless indicated 
otherwise in the specific use directions. 
Application with ground equipment is preferable to aerial appli cation, because ground applications 
generally give better coverage of the tree canopy. If applicati on with ground equipment is not feasible, 
Praiz Fungicide may be applied with aircraft using at least 20 gallons of spray per acre. 
When concentrate sprays are used or when treating non-bearing o r immature trees, the lower rate of 
Praiz Fungicide listed may be used. 
Restriction: Do not allow livestock to graze in treated areas.

Use water volumes of 20 to 300 
gallons per acre. For blossom blight, 
begin application at popcorn (pink 
bud) and follow with an application at 
full bloom. If weather is still conducive 
for disease development, another 
application may be made at petal fall.
For control of shot hole, make an
application in the autumn at leaf fall. 
In the spring, make the first 
application at budbreak, followed by 
an application at shuck split to control 
nut infections and to control scab.
Dormant applications for scab: Apply
before bud swell (generally December 
1 through January 10). Apply 4 pints 
Praiz Fungicide with 4 gal of 
agricultural spray oil per acre. 
For control of anthracnose, apply 4 
pints/A.
Apply by ground or air.
Specific Use Restrictions:
1) Do not apply more than 25 pints of Praiz Fungicide (18.75 Ib. a.i.) per acre per year (leaf fall through shuck 
split).
2) Pre-harvest Interval (PHI): Do not apply within 150 days of h arvest.

Use a water volume of 20 to 300 
gallons per acre. Begin applications at 
the onset of disease or when weather 
conditions favor disease development. 
Make applications on a 14 to 28-day 
schedule, using the shorter interval 
under heavy disease pressure (the 
minimum retreatment interval is 14 
days).
Specific Use Restrictions:
1) Do not apply more than 12 pints of Praiz Fungicide (9.0 Ib. a. i.) per acre per year.
2) Pre-harvest Interval (PHI): Do not apply within 120 days of h arvest.

For best control of both diseases, apply 
at leaf fall in late autumn, using sufficient 
water and proper sprayer calibration to 
obtain uniform coverage. 
When conditions favor high disease 
levels, use the high rate of application 
and apply once or twice more in mid to 
late winter before budswell. If the leaf fall 
application is not practical, application of 
Praiz Fungicide for control of leaf curl 
may be made at any time prior to 
budswell the following spring. Where 
shot hole occurs, also apply at budbreak 
to protect newly emerging leaves and at 
shuck split to prevent fruit infections.
Apply by ground or air.

shuck split and before harvest. If 
additional disease control is needed 
before harvest, use another registered 
fungicide. 
For control of cherry leaf spot after 
harvest, make one application to foliage 
within 7 days after fruit is removed. In 
orchards with a history of high leaf spot 
incidence, make a second application 10 
to 14 days later.
Apply by ground or air.
Specific Use Restrictions:
1) Do not apply more than 20 ½ pints of Praiz Fungicide (15.4 Ib. a.i.) per acre per year.
2) The minimum re-treatment interval is 10 days.
3) Praiz Fungicide may be applied through shuck split. Praiz Fun gicide may then again be applied after harvest as 
indicated.
