Widely used in agriculture as a fungicide, particularly effective against diseases caused by oomycetes such as downy mildew and Phytophthora in crops like potatoes, tomatoes, grapes, and ornamental plants. It works by interfering with cell wall synthesis in fungal pathogens, providing both protective and systemic action. Applied through foliar spray or soil drench, it is favored for its low toxicity to beneficial organisms and rapid degradation in the environment, making it suitable for integrated pest management programs. Commonly used in vegetable farming and vineyards to control blight and root rot under humid conditions.
