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. Famoxadone works by inhibiting mitochondrial respiration in fungi, disrupting their energy production and leading to cell death. Due to its systemic and translaminar movement in plant tissues, it provides both protective and early curative action. It is often formulated in combination with other fungicides to enhance efficacy and reduce the risk of resistance development. Its application is typically done through foliar spray, offering reliable disease control under favorable conditions for fungal growth.
