Widely used in agriculture as a fungicide, particularly effective against diseases caused by oomycetes such as downy mildew and late blight in crops like potatoes, tomatoes, and grapes. It works by interfering with cell wall synthesis in the pathogen, providing both protective and systemic action. Commonly applied as a foliar spray or soil drench, it is favored for its low toxicity to mammals and rapid degradation in the environment, making it suitable for integrated pest management programs. Often used in combination with other fungicides to enhance efficacy and reduce resistance development.
