Procymidone is primarily used as a fungicide in agricultural settings. It is effective in controlling a broad spectrum of fungal diseases, especially those caused by Botrytis, Alternaria, and Penicillium species. It is commonly applied to fruits, vegetables, and ornamental crops to prevent gray mold and other fungal infections during growth and post-harvest storage. Due to its protective and curative properties, it helps extend shelf life and reduce crop losses. Procymidone works by inhibiting fungal spore germination and mycelial growth, making it valuable in integrated pest management programs. Its use is especially prominent in vineyards, orchards, and greenhouse production systems.
