POTATOES - LATE BLIGHT
TANOS is a broad-spectrum protectant fungicide, recommended for control of many important plant diseases. It has curative and locally systemic activities against downy mildew and late blight diseases.
TANOS must be applied in a regularly scheduled protective spray program in rotation with other fungicides. See directions below for specific crop/disease recommendations.
TANOS can be applied with ground, air or chemigation equipment, except as otherwise directed, using sufficient water to obtain thorough coverage of plants. Use only in commercial or farm plantings. Not intended for use in home plantings.
Rainfastness: TANOS rapidly penetrates into plant tissues and is rainfast within 1 hour after application.
INTEGRATED PEST MANAGEMENT
DuPont recommends the use of Integrated Pest Management (IPM) programs to control pests. This product may be used as part of an Integrated Pest Management (IPM) program which can include biological, cultural, and genetic practices aimed at preventing economic pest damage. Application of this product should be based on IPM principles and practices including field scouting or other detection methods, correct target pest identification, population monitoring, and treating when disease forecasting models reach locally determined action levels. Consult your state cooperative extension service, professional consultants or other qualified authorities to determine the appropriate management, cultural practice and treatment threshold levels for the specific crop, geography and diseases.
Repeated use of products for control of specific plant pathogens may lead to selection of resistant strains of fungi and result in a reduction of disease control. Famoxadone, one of the active ingredients in TANOS, is one of EPA’s Target Site of Action Group 11 fungicides, which also includes all strobilurins and fenamidone. A disease management program that includes rotation between TANOS and other non-Group 11 fungicides is essential to reduce the risk of fungicide resistance development. Tank-mixing TANOS with a protectant (contact) fungicide that has a different mode of action is required. This ensures optimum performance and further reduces the potential for resistance development. For guidance on the particular crop and disease control situation, consult your state extension specialist or official state recommendations.
- Calibrate sprayers only with clean water away from the well site.
- Make scheduled checks of spray equipment.
- Ensure accurate measurement of pesticides by all operation employees.
- Mix only enough product for the job at hand.
- Avoid overfilling of spray tank.
- Do not discharge excess material on the soil at a single spot in the field/grove or mixing/loading station.
- Dilute and agitate excess solution and apply at labeled rates/uses.
- Avoid storage of pesticides near well sites.
- When triple rinsing the pesticide container, be sure to add the rinsate to the spray mix.
Refer in the label regarding tank mix information.
Resistance Management: Do not make more than one application of DuPont TANOS before alternating with a fungicide that has a different mode of action, such as mancozeb, chlorothalonil, etc. Do not make more than six (6) applications of TANOS or other Group 11 fungicides per cropping cycle. Do not alternate or tank mix with other Group 11 fungicides or with fungicides to which resistance has developed.
- TANOS applications should begin prior to disease development, following the resistance management instructions, above.
- For early blight control, make fungicide applications on a 7- to 10-day interval. Use shorter intervals when disease is present in the area or if weather conditions favor disease development.
- For preventive late blight control, make fungicide applications on a 7-10 day interval. When weather conditions favor late blight development or late blight is present in the area, use the 8 oz/acre rate of TANOS and shorten the interval to 5-7 days.
- TANOS must be tank-mixed with an appropriate contact fungicide that has a different mode of action, such as mancozeb, chlorothalonil, etc. Follow all tank-mix partner label restrictions using at least the minimum labeled rates of each fungicide.
Application volume instructions:
- For ground application, apply a minimum of 20 gallons of spray volume per acre, increasing the spray volume as plants mature to ensure thorough coverage of foliage.
- For aerial application, apply a minimum of 5 gallons per acre.
