Tanos is a fungicide used for the control of various fungal diseases in a wide range of crops, including bulb vegetables (onions, garlic, leeks), cucurbits, grapes, and hops. It contains two active ingredients: Famoxadone and Cymoxanil. The product is designed for both ground and aerial applications. For ground applications, it can be applied using various methods such as air or chemigation equipment, though specific precautions apply when using irrigation systems. When applied via chemigation, the product must be mixed with water to ensure proper dilution. The label emphasizes resistance management, advising users not to make more than one application of Tanos before alternating with a fungicide that has a different mode of action (such as copper, Mancozeb, or chlorothalonil). Users should not exceed a specific number of applications per cropping season to prevent resistance development. When handling, personal protective equipment (PPE) including chemical-resistant gloves, protective eyewear, and respiratory protection may be required depending on the application method. Always follow specific instructions for mixing, especially when tank-mixing with other fungicides or using specialized equipment like irrigation systems.
