Procymidone is a fungicide primarily used in agriculture to control a wide range of fungal diseases in crops. It is effective against fungi such as Botrytis, Alternaria, and Sclerotinia, which commonly affect fruits, vegetables, and ornamental plants. It is often applied to crops like grapes, strawberries, onions, and lettuce to prevent mold and rot during growth and storage. The solution formulation allows for easy mixing and spraying, ensuring uniform coverage on plant surfaces. Procymidone works by inhibiting spore germination and mycelial growth, making it a preventive treatment rather than a curative one. Due to its persistence, it provides long-lasting protection under favorable disease conditions. It is also used in research settings to study fungal resistance and mode of action of dicarboximide fungicides. Careful application is required to minimize environmental impact and avoid buildup of resistant fungal strains.
