Used as a fungicide in agriculture, particularly for controlling downy mildew and other fungal diseases in crops like grapes, potatoes, and vegetables. It is effective in protecting plants when applied preventively, as it inhibits spore germination and mycelial growth. Commonly formulated in combination with other fungicides to enhance efficacy and reduce the risk of resistance development. Widely applied through foliar spraying in vineyards and fields during growing seasons prone to high humidity or rainfall, where fungal infections are more likely.
