Used as a fungicide in agriculture, particularly effective against diseases caused by oomycetes such as downy mildew and late blight in crops like potatoes, tomatoes, grapes, and ornamental plants. It works by interfering with cell wall synthesis and lipid metabolism in the pathogen, preventing spore formation and mycelial growth. Applied as a foliar spray or soil drench, it is valued for its systemic action, allowing it to move within plant tissues to protect new growth. Commonly used in integrated pest management programs due to its favorable environmental profile and low toxicity to non-target organisms.
