POME FRUITS - SCAB (PREVENTATIVE) - DISEASE CONTROL

General Information

PRODUCT INFORMATION

Flint Fungicide is a broad spectrum fungicide for the control of certain diseases when using foliar applications on asparagus, cucurbit vegetables, fruiting vegetables, grapes, grasses grown for seed, hops, leafy petiole vegetables, pome fruits, root vegetables, strawberries, and tropical fruits.

Flint Fungicide works by interfering with respiration in plant pathogenic fungi. Flint Fungicide is a potent inhibitor of spore germination and mycelial growth. UNDER CERTAIN CONDITIONS CONDUCIVE TO EXTENDED INFECTION PERIODS, ADDITIONAL FUNGICIDE APPLICATIONS BEYOND THE NUMBER ALLOWED BY THIS LABEL MAY BE NEEDED.

UNDER THESE CONDITIONS, USE ANOTHER FUNGICIDE REGISTERED FOR THE CROP/DISEASE APPEARING ON THE LABEL.

DO NOT APPLY FLINT FUNGICIDE TO CONCORD GRAPES OR CROP INJURY MAY OCCUR.

GREENHOUSE APPLICATIONS: DO NOT APPLY THIS PRODUCT IN GREENHOUSES.

Resistance Management

Flint Fungicide belongs to the QoI (Group 11) target site of action group and exhibits no known cross-resistance to other chemical classes including sterol inhibitors, dicarboximides, benzimidazoles, anilinopyrimidines, or phenylamides. Trifloxystrobin (the active ingredient in Flint Fungicide) exhibits cross-resistance to other Group 11 fungicides such as azoxystrobin and kresoxim-methyl. When products with the same mode of action are used repeatedly, fungal pathogens can develop resistance to those products.

Because resistance development cannot be predicted, the use of this product should conform to resistance management strategies established for the crop and use area. Such strategies may include rotation and/or tank mixing with products having different modes of action, or limiting the total number of applications per season.

The North American Fungicide Resistance Action Committee - QoI Working Group (NA-FRAC) recommends: 1) QoI fungicides be used in a preventative manner. 2) When employing tank mixtures for resistance management, use fungicides from different target site Groups that are registered or permitted for the same use, are effective against the pathogen of concern, and are used at not less than the minimum-labeled rates of each fungicide in the tank mix. 3) For resistance management purposes, in-furrow applications utilizing Group 11 fungicides are not counted as foliar applications to determine the maximum number of sequential sprays or the total number of sprays per season.

Follow the specific crop use directions that limit the total number of sprays on a crop and the required alternations with fungicides from other resistance management groups as directed on the label. In situations requiring multiple fungicide sprays, develop season long spray programs for Flint Fungicide and other Group 11 fungicides. In a program using a Group 11 fungicide as a solo product, the number of applications should be no more than 1/3 of the total number of fungicide applications per season. In programs in which tank mixes or pre-mixes of a Group 11 fungicide together with a fungicide of another Group are utilized, the number of Group 11 fungicide applications should be no more than 1/2 of the total number of fungicide applications per season. In programs in which applications of Group 11 fungicides are made with both solo products and mixtures, the number of Group 11 fungicide applications should be no more than 1/2 of the total number of fungicide applications per season. Bayer CropScience encourages responsible resistance management to ensure effective long-term control of the fungal diseases on the label.

IPM: Applications of fungicides should be integrated into an overall disease and pest management program. Cultural practices known to reduce disease

development should be followed. Consult your local extension specialist, certified crop advisor and/or manufacturer representative for additional IPM strategies established for your area. Flint Fungicide may be used in Agricultural Extension advisory (disease forecasting or risk assessment) programs that recommend application timings based on environmental factors favorable for disease development.

Product performance: Monitor efficacy of all fungicides used in the disease management program against the targeted pathogen by recording factors that may influence fungicide performance and/or disease development. If a fungicide appears to be less effective against a pathogen that it previously controlled or suppressed, contact a manufacturer representative, local extension specialist, or certified crop advisor for further investigation.

USE DIRECTIONS FOR SPECIFIC CROPS

Flint Fungicide provides control or suppression of several important diseases when using foliar applications on asparagus, cucurbit vegetables, fruiting vegetables, grapes, grasses grown for seed, hops, leafy petiole vegetables, pome fruits, root vegetables, strawberries, and tropical fruit.

When reference is made to disease suppression, suppression can mean either erratic control from good to fair or consistent control at a level below that obtained with the best commercial disease control products.

Application Timing

Begin applications at green tip and continue as needed on a 7- to 10-dayinterval.

Notes

Flint will provide up to 72 hours of post-infection control under moderate to heavy disease pressure and up to 96 hours of post-infection control of apple scab under light disease pressure. Applications should be made preventatively or as soon as possible following a scab infection period and followed up within 7 to 10 days with another application of Flint or another fungicide labeled for the control of scab. A reliable infection forecasting system must be used.

Do not use in Lake and Mendicino counties (California) to control pear scab.

Restrictions: To reduce the potential for resistance, limit Group 11 fungicides to two sequential applications and alternate with at least two applications of fungicides from a different Group before making a third application with a Group 11 fungicide. Do not apply Flint where spray drift may reach Concord grapes or crop injury may occur. Spray equipment should be rinsed after applying Flint before application of other products to Concord grapes or crop injury may occur.
