Famoxadone is primarily used as a fungicide in agriculture, especially for controlling fungal diseases in crops such as grapes, potatoes, tomatoes, and leafy vegetables. It is effective against a broad spectrum of oomycete pathogens, including those causing downy mildew and late blight. The solution formulation allows for easy mixing and application through foliar sprays, providing protective and curative action. It works by inhibiting mitochondrial respiration in fungi, which stops their growth and spread. Due to its systemic properties, famoxadone is absorbed by plant tissues and offers residual protection, making it suitable for integrated pest management programs. It is often combined with other fungicides to enhance efficacy and reduce the risk of resistance development.
