TURFGRASS - FAIRY RING - CURATIVE
This labeling MUST be in possession of the user at the time of pesticide application.
ProStar 70 WG Fungicide is a systemic fungicide for the control or suppression of listed foliar and soil borne diseases caused by basidiomycete fungi in turf and ornamentals.
For use on:
- Turf in golf courses, sod farms, sports fields, residential, institutional, municipal and commercial areas.
- Container ornamentals in nurseries, greenhouses and shade houses.
- Field grown ornamentals in nurseries and landscapes.
Apply this product only through pressurized drench (flood), sprinkler, or drip (trickle) irrigation systems. Do not apply this product through any other type of irrigation systems.
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, contact State Extension Service specialists, equipment manufacturers, or other experts.
Do not connect any 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.
Pesticide supply tanks are prescribed for the application of this product. See label instructions for dilution use rates and timing of application.
Agitate continuously during application.
OVERHEAD, MICROJET, OR DRIP IRRIGATION APPLICATION
ProStar 70 WG Fungicide alone or in tank mixture with other pesticides which are registered for overhead, microjet, or drip application may be applied in irrigation water at rates on this label. Follow the label directions for the most restrictive of label limitations and precautions.
This product cannot be mixed with any product containing a label prohibition against such mixing.
Apply this product only through an overhead, microjet, or drip irrigation system. Do not apply this product through any other type of irrigation system. Plant injury or lack of effectiveness can result from nonuniform distribution of treated water. If you have questions about calibration, contact State Extension 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 device 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. Public water system means a system for the provision to the public of piped water for human consumption if such system has a least 15 service connections or regularly serves an average of at least 25 individuals daily or at least 60 days out of the year.
- 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 back flow. Chemigation systems connected to public water systems must contain a functional, reduced-pressure zone, back-flow preventer (RPZ) or the functional equivalent in the water supply line upstream from the point of pesticide 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 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.
- 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 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 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 functional 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, 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.
- Prepare a mixture with a minimum of 1 gallon of water per 1 ounce of ProStar 70 WG Fungicide, and inject this mixture into the system. Injecting a larger volume of a more dilute mixture per hour will usually provide more accurate calibration of metering equipment. Maintain sufficient agitation to keep the fungicide in suspension.
- Meter into irrigation water during the beginning of the irrigation cycle.
- With overhead or microjet systems, apply enough water to thoroughly wet the potting media.
Precaution for irrigation applications: Where distribution patterns do not overlap sufficiently, unacceptable control may result. Where distribution patterns overlap excessively, injury to desirable plants may result.
DIRECTIONS FOR USE ON TURF
TURF USE RESTRICTIONS
- Do not apply more than 4.5 oz of ProStar 70 WG Fungicide/1,000 sq. ft./application (8.6 lbs flutolanil/acre/application).
- Do not apply more than 9 oz of ProStar 70 WG Fungicide/1,000 sq. ft./Year (17.1 lbs flutolanil/acre/year).
- For use rates over 2.2 oz per 1,000 sq. ft. do not apply ProStar 70 WG Fungicide within 100 ft. of any estuary or marine habitat or within 100 ft. of any ditches, drainage tiles, or other waterways that drain directly into (within 1/2 mile of) estuaries or marine habitats.
- Do not use ProStar 70 WG Fungicide on turf in Nassau and Suffolk Counties of New York State. Use in Nassau and Suffolk Counties is limited to drench application to container grown ornamentals in greenhouses only. Please see specific directions.
APPLICATIONS FOR TURF DISEASES CONTROL
ProStar 70 WG Fungicide is a systemic fungicide for control of diseases of turf caused by Basidiomycetes such as Brown Patch (Rhizoctonia solani), Brown Ring Patch (Waitea circinata var. circinata), Fairy Ring (various basidiomycetes species), Red Thread (Laetisaria fuciformis), Pink Patch (Limonomyces roseipellis), Yellow Patch (Rhizoctonia cerealis), Southern Blight (Sclerotium rolfsii), Gray snow mold (Typhula spp.), Large Patch (Rhizoctonia solani AG 2-2LP) and Leaf and Sheath spot (Rhizoctonia zeae).
Apply the prescribed amount of ProStar 70 WG Fungicide in 2 to 5 gallons of water per 1,000 square feet as a broadcast application. If ProStar 70 WG Fungicide is to be tank mixed with an appropriately labeled fungicide or other product to control another pest, add ProStar 70 WG Fungicide first. Prior to spraying with a tank mixture not specified on this label, it is advisable to determine if the products are physically compatible.
For best results, spray the treated area uniformly, using equipment such as flat fan nozzles. Use 50-mesh or larger screens. Avoid mowing for 24 hours after application and do not irrigate until spray has dried, unless otherwise noted. When non-labeled diseases are also present, ProStar 70 WG Fungicide may be tank mixed with appropriate labeled fungicides if the products are physically compatible.
ProStar 70 WG Fungicide has excellent safety on the following turfgrass varieties: Kentucky bluegrass, creeping bentgrass, perennial ryegrass, annual bluegrass, red fescue, tall fescue, bermudagrass, St. Augustinegrass, and zoysiagrass.
TURF SPECIFIC USE DIRECTIONS
Start preventive treatments prior to initial sign of disease and when conditions favor disease development.
- Use alone or as part of a seasonal fairy ring program with Bayleton® Flo, or Tartan Stressgard.
- Irrigate immediately or within the next irrigation cycle to the depth of the fairy ring in the thatch, mat or soil profile.
Timing (days): 28
