GENERAL INFORMATION
ARYSTA PROPICONAZOLE 41.8 EC FUNGICIDE is a broad spectrum fungicide for the control of specified diseases in labeled crops. Do not use this product in greenhouses or as a tree injection.

SPRAY EQUIPMENT
In general, the most effective disease control is achieved when applications are made using sufficient water volume to provide thorough and uniform coverage.
To avoid spray drift, do not apply when conditions favor drift beyond the target area. Avoid spray overlap as crop injury may occur.
Air-assisted or air-blast sprayers use a forced air stream to move spray droplets into the canopy. Set up the fan to deliver only enough air volume to penetrate the canopy and provide good coverage. Adjust deflectors or other aiming devices to direct spray only to the target area.
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 maintain 35-40 psi at nozzles and provide sufficient agitation in tank to keep mixture in suspension. Use a jet agitator, liquid sparger tube, or mechanical paddle for agitation. Do not air sparge.
Although this product is an emulsifiable 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 agricultural experiment station recommendations.

APPLICATION INSTRUCTIONS
For best results, sufficient water volume should be used to provide thorough coverage. In most situations, this product is most effective when applied and allowed to dry before a rainfall. Avoid application under conditions when uniform coverage cannot be obtained or when excessive spray drift may occur. Do not apply directly to humans or animals.
Aerial Application: For those crops other than tree crops where aerial applications are indicated, apply in a minimum of 2 gals of water per acre, unless specified otherwise in the CROP APPLICATION INSTRUCTIONS section of this label. For tree crops, a minimum of 5 to 10 gals of water per acre is specified using the higher volume on large trees unless specified otherwise in the CROP APPLICATION INSTRUCTIONS section of this label.
Ground Application: For tree crops, a minimum of 50 gals of water per acre is specified unless specified otherwise in the CROP APPLICATION INSTRUCTIONS section of this label. For all other crops, apply this product by ground equipment in a minimum of 10 gals of water per acre unless specified otherwise in the
CROP APPLICATION INSTRUCTIONS section of this label.
Chemigation: Apply this product through irrigation equipment only to crops for which chemigation is specified on this label or on approved supplemental labeling provided by ARYSTA LIFESCIENCE NORTH AMERICA, LLC.
Apply in 0.1 to 0.25 inches of water. Chemigation with excessive water negatively impacts efficacy of the product.
Precaution(s): Do not inject this product at full strength or deterioration of valves and seals will occur. Use a dilution ratio of at least 10 parts water to 1 part product. This product is corrosive to many seal materials.
Leather seals are best. EPDM or silicone rubber seals can be used but should be replaced once a year.
Do not use Viton, Buna-N, Neoprene, or PVC seals.
Apply this product through irrigation systems alone or in combination with other pesticides which are registered for application through irrigation systems.
Apply this product only through center pivot, solid set, hand move, or moving wheel irrigation systems. 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 should contact 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 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.
Irrigation System Operating Instructions
x 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.
x The pesticide injection pipeline must contain a functional, automatic, quick closing check-valve to prevent the flow of fluid back toward the injection pump.
x 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 being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down.
x The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops.
x 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.
x 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.
x Do not apply when wind speed favors drift beyond the area intended.
Center Pivot Irrigation Equipment
Use only with drive systems which provide uniform water distribution. Do not use end guns when applying this product through center pivot systems because of non-uniform application.
x Determine the size of the area to be treated.
x Determine the time required to apply 1/8 to 1/2 inch of water over the area to be treated when the system and injection equipment are operated at normal pressures as specified by the equipment manufacturer. When applying this product through irrigation equipment, use the lowest obtainable water volume while maintaining uniform distribution. Run the system at 80% to 95% of the manufacturer's rated capacity.
x Using water, determine the injection pump output when operated at normal line pressure.
x Determine the amount of this product required to treat the area covered by the irrigation system.
x Add the required amount of this product and sufficient water to meet the injection time requirements to the solution tank.
x Make sure the system is fully charged with water before starting injection of the product solution.
x Time the injection to last at least as long as it takes to bring the system to full pressure.
x Maintain constant solution tank agitation during the injection period.
x Continue to operate the system until the product solution has cleared the sprinkler head.
Solid Set, Hand Move, and Moving Wheel Irrigation Equipment
x Determine the acreage covered by the sprinklers.
x Fill injector solution tank with water and adjust flow rate to use the contents over a 20- to 30-minute interval. When applying this product through irrigation equipment, use the lowest obtainable water volume while maintaining uniform distribution.
x Determine the amount of this product required to treat the area covered by the irrigation system.
x Add the required amount of this product into the same quantity of water used to calibrate the injection period.
x Operate the system at the same pressure and time interval established during the calibration.
x Stop injection equipment after treatment is completed. Continue to operate the system until the product solution has cleared the last sprinkler head.
Banded Application: For banded applications, the treated area is the area covered by the band, not total cropland planted. The following formula can be used to calculate the amount of this product needed per acre of crop when banded applications are made:
Band width in inches x Broadcast rate per acre = Amount needed per acre of field Row spacing in inches
