TURF - GRAY LEAF SPOT
Heritage Fungicide is a broad-spectrum, systemic fungicide that prevents or controls the listed pathogens that cause foliar, stem, and root diseases, including leaf and stem blights, leaf spots, patch diseases, mildews, anthracnose, fairy rings, molds, and rusts of turfgrass, ornamentals, vegetables, and herbs. Heritage Fungicide may be applied in alternating application programs or in tank mixes with other registered plant protection products. All applications must be made according to the use directions that follow. Heritage Fungicide is a member of Syngenta’s Plant Performance product line that can improve plant vigor and quality. The additional benefits are due to positive effects on plant physiology, which can vary according to plant species and growing environment.
USE PRECAUTIONS AND RESTRICTIONS
Adjuvants: When an adjuvant is to be used with this product, the use of an adjuvant that meets the standards of the Chemical Producers and Distributors Association (CPDA) adjuvant certification program is recommended.
DO NOT apply more than 10 lb of Heritage Fungicide (5 lb ai) per acre per year to crops grown outdoors.
DO NOT apply more than 1.1 lb of Heritage Fungicide (0.55 lb ai) per acre per application.
DO NOT graze or feed clippings from treated turf areas to animals.
Heritage Fungicide is highly phytotoxic to apple and certain crabapple and flowering cherry varieties. Use caution to prevent injury to these trees. DO NOT use spray equipment that has been used to apply Heritage Fungicide to spray apple, crabapple and flowering cherry trees. Even trace amounts can cause unacceptable phytotoxicity.
SPRAY DRIFT MANAGEMENT
DO NOT apply Heritage Fungicide when conditions favor drift beyond the area intended for application. Conditions that can contribute to drift include thermal inversion, wind speed and direction, sprayer nozzle and pressure combinations, and spray droplet size. Contact your State extension agent for spray drift prevention guidelines in your area.
DO NOT apply Heritage Fungicide where spray drift may reach apple, crabapple, or flowering cherry trees.
DO NOT apply when weather conditions favor drift from treated areas to a non-target aquatic habitat.
AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR.
INTEGRATED PEST (DISEASE) MANAGEMENT (IPM)
Heritage Fungicide should be integrated into an overall disease and pest management strategy whenever the use of a fungicide is required. Cultural practices known to reduce disease development, such as planting of resistant cultivars, removal of plant debris to reduce inoculum, and water management, should be followed. The following sections in the label identify specific IPM recommendations for each crop. Consult your local agricultural, turf and ornamental authorities for additional IPM strategies established for your area.
Heritage Fungicide may be used in State Agricultural Extension advisory (disease forecasting) programs that recommend application timing based on environmental factors favorable for disease development.
Some plant pathogens have been shown to develop resistance to fungicide products used repeatedly for their control. Heritage Fungicide should be applied at full label-use rates and in a tank mix or a rotation with other registered fungicides that have a different mode of action. As Heritage Fungicide is a strobilurin (Group 11) fungicide, DO NOT alternate with other strobilurins, such as pyraclostrobin and trifloxystrobin. DO NOT alternate or tank-mix Heritage Fungicide with fungicides to which resistance has already developed. Since pathogens differ in their potential to develop fungicide resistance, use the resistance management strategies for each disease given in the SPECIFIC USE DIRECTIONS section in the label.
Syngenta Crop Protection encourages responsible resistance management to ensure effective long-term control of the fungal diseases on the label. Consult your local or state Extension Service for resistance management strategies that are complementary to those in the label.
To prepare spray solution, partially fill the spray tank with clean water and begin agitation.
Add the specified amount of Heritage Fungicide to the tank, allowing adequate time for good mixing. Add an adjuvant if recommended. Finish filling the tank to the desired volume to obtain the proper spray concentration. Maintain agitation throughout the spraying operation. DO NOT allow spray mixture to stand overnight or for prolonged periods. Mix only the amount of spray required for your immediate use. Sprayers should be thoroughly cleaned immediately after application.
Heritage Fungicide is compatible with commonly used fungicides, liquid fertilizers, herbicides, insecticides and biological control products. If tank mixes are desired, products should be added to the spray tank in the following order: Heritage Fungicide, other WG or dry flowable formulations, wettable powders, and flowable (aqueous suspension) products. Observe all directions, precautions, and limitations on labeling of all products used. Consult compatibility charts or your local or state agricultural or turf authorities for compatibility information.
DO NOT mix Heritage Fungicide in the spray tank with pesticides, surfactants or fertilizers unless compatibility charts or your own prior use has shown that the combination is physically compatible, effective and non-injurious under your conditions of use. If physical compatibility is unknown, the following procedure should be followed: Pour the recommended proportions of the products into a suitable container of water, mix thoroughly and allow it to stand at least 20 minutes. If the combination remains mixed or can be re-mixed readily, the mixture is considered physically compatible.
Heritage Fungicide is incompatible with many fertilizers when low water volumes are used for in-furrow applications. Cold temperatures and water quality exacerbate these compatibility problems. Conduct a physical compatibility test as described in the paragraph as above before making a field application.
NOTE: Heritage Fungicide has demonstrated some phytotoxic effects when mixed with products that are formulated as EC’s. These effects are enhanced if applications are made under cool, cloudy conditions and these conditions remain for several days following application.
In addition, silicone-containing adjuvants have also contributed to phytotoxicity.
Heritage Fungicide should be applied prior to disease development at the rates and timings given in the label. Apply at the higher rates in the rate range and/or shorter spray intervals under conditions of heavy infection pressure, on highly susceptible varieties or when environmental conditions are conducive for disease development. Use of Heritage Fungicide as a “rescue” (late curative or eradicant) treatment may not give satisfactory disease control.
Heritage Fungicide may be applied with various types of spray equipment commonly used for making ground and aerial applications. For ground applications, apply Heritage Fungicide in a volume of water sufficient to provide good plant canopy penetration. For aerial applications, apply Heritage Fungicide in a minimum of two gallons of water per acre. Ground application is preferred as it typically provides better canopy penetration and coverage.
Proper adjustments and calibration of spraying equipment are essential for optimal disease control. If you have questions about calibration, contact a State Extension Service specialist, the equipment manufacturer or other experts.
Directions for Use through Sprinkler and Drip Chemigation Systems
Spray Preparation: Chemical tank and injector system should be thoroughly cleaned. Flush system with clean water.
Use Precautions for Sprinkler and Drip Irrigation Applications:
Drip and Micro Irrigation: Heritage Fungicide may be applied through drip and micro irrigation systems to potted ornamentals or to bedded, field-grown ornamentals for soil-borne disease control. The soil or potting media should have adequate moisture capacity prior to drip application.
Terminate drip irrigation at fungicide depletion from the main feed supply tank or after 6 hours from start, whichever is shorter. For maximum efficacy, subsequent irrigation (water only) should be delayed for at least for 24 hours following drip application.
Sprinkler Irrigation: Apply this product through sprinkler irrigation systems including center pivot, motorized boom, lateral move, end tow, side [wheel] roll, traveler, big gun, solid set, or hand move irrigation systems. Do not apply this product through any other type of irrigation system except as specified on the label.
Apply with center-pivot or continuous-move equipment distributing 1/2 acre-inch or less during treatment. In general, use the least amount of water required for proper distribution and coverage. If stationary systems (solid set, handlines or wheel lines other than continuous-move) are used, this product should be injected into no more than the last 20-30 minutes of the set. DO NOT apply when winds are greater than 10-15 mph to avoid drift or wind skips. Plant injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non-uniform treated water. Thorough coverage of foliage is required for good control. Good agitation should be maintained during the entire application period. If you have questions about calibration, contact the State Extension Service specialist, equipment manufacturers or other experts.
- 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.
- 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. Allow sufficient time for 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 should the need arise.
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 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 out of the year.
2. 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 should be discharged into a reservoir tank prior to pesticide introduction. There must 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 interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops, or in cases 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, 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.
7. Do not apply when wind speed favors drift beyond the area intended for treatment.
DIRECTIONS FOR TURF
Heritage Fungicide is recommended for control of the listed pathogens that cause foliar, stem, and root diseases, including leaf and stem blights, leaf spots, patch diseases, mildew, molds and rusts of turfgrass. Heritage Fungicide may be used on golf courses, lawns and landscape areas around residential, institutional, public, commercial and industrial buildings, parks, recreational areas, athletic fields, and sod farms.
Integrated Pest (Disease) Management (IPM)
Sound turf management resulting in healthy, vigorous turf is the foundation of a good IPM program. Cultural practices, such as proper choice of turf variety, nutrient management, proper cutting height, thatch management, and proper watering, drainage, and moisture stress management, should be integrated with the use of fungicides to increase turf vigor and reduce the susceptibility to disease. Immunoassay detection kits and extension service diagnostic services can assist in the early and accurate identification of causal organisms and corresponding selection of the proper fungicide when required.
DO NOT spray more than two sequential Heritage Fungicide applications for Gray Leaf Spot or Pythium spp. control. For all other diseases when Gray Leaf Spot and Pythium spp. Are not present, DO NOT spray more than three sequential applications of Heritage Fungicide.
Heritage Fungicide should be applied prior to disease development. Mix Heritage Fungicide with the required amount of water and apply as a dilute spray application in 2-4 gallons of water per 1,000 square feet (87-174 gallons per acre). Repeat applications at specified intervals. For spot treatments, use 0.2 oz of Heritage Fungicide per 1-2 gallons of water.
DO NOT apply to golf course turf by air.
Soil Injection Application
Heritage Fungicide may be applied through a liquid fungicide injector for the control of ectrotrophic root diseases such as summer patch and take-all patch. Use Heritage Fungicide only in liquid injection equipment specifically designated for pesticide use. Apply Heritage Fungicide at 0.2 to 0.4 oz per 1,000 sq ft. Spray carrier volume should fall within 30-150 gallons of water per 1,000 sq ft. Injection hole spacing of 1 inch by 1 inch is recommended for optimum control. Do not exceed injection depth of 2 inches. One-inch depth is recommended for optimum results. Application timing should follow disease control strategies used for normal broadcast spray programs.
Application when Establishing Turfgrass from Seed or in Overseeding of Dormant Turfgrass
Heritage Fungicide may be used for control of certain turfgrass diseases associated with turfgrass establishment from seed or during overseeding of dormant turfgrass. Heritage Fungicide may be safely applied before or after seeding or at seedling germination and emergence to ryegrass, bentgrass, bluegrass (including Poa trivialis), and fescue turfgrass types. Optimum application timing is during seeding. See Application Directions section.
Dollar Spot: Heritage Fungicide does not control Dollar Spot. During periods of Dollar Spot pressure, always mix Heritage Fungicide with Daconil, Banner Maxx, Secure, or other Dollar Spot control fungicide. Heritage Fungicide is compatible in tank mixes with many other fungicides that control Dollar Spot. Follow directions under MIXING INSTRUCTIONS.
Do not apply more than two sequential applications of Heritage Fungicide for control of Gray Leaf Spot and Pythium spp. For all other diseases when Gray Leaf Spot and Pythium spp. are not present, do not apply more than three sequential applications of Heritage Fungicide.
Application Interval (days) - 14-28
