Ferbam is primarily used as a fungicide in agriculture. It is effective in controlling a wide range of fungal diseases in crops, especially in fruits and vegetables. Common applications include the protection of grapes, potatoes, and ornamental plants from fungal infections such as downy mildew, blight, and leaf spots. It is often applied as a foliar spray and works by inhibiting fungal enzyme activity, disrupting energy production within the fungal cells. Due to its broad-spectrum activity, Ferbam is valued in integrated pest management programs, particularly where resistance to other fungicides has developed. Ferbam is also used in seed treatment to prevent soil-borne fungal pathogens during germination and early plant growth. Its relatively short residual activity makes it suitable for use in rotation with other fungicides to reduce the risk of resistance buildup. In non-agricultural settings, Ferbam has been used in industrial applications to control mold and mildew on surfaces, including in paints, adhesives, and cooling systems. However, its use in such areas is limited due to regulatory and environmental considerations.
