Widely used as a protective fungicide in agriculture, especially for controlling fungal diseases in crops such as potatoes, tomatoes, grapes, and ornamental plants. It is effective against a range of fungal pathogens including those causing blight, mildew, and leaf spots. Commonly applied as a foliar spray, it forms a protective barrier on plant surfaces, preventing spore germination and fungal penetration. Due to its protective action, it is often used in preventive disease management programs, particularly in humid or wet conditions where fungal outbreaks are more likely. It is also used in seed treatment to protect germinating seeds from soil-borne fungi. Its stability under sunlight and resistance to wash-off by rain make it suitable for outdoor field use.
