Fenfuram is primarily used as a fungicide in agriculture, especially in the control of soil-borne fungal diseases. It is effective against a range of pathogenic fungi that affect crop roots and stems, helping to protect plants such as vegetables, tobacco, and ornamental crops. Its application is common in seed treatment and soil drenching, where it prevents damping-off and root rot caused by fungi like Fusarium and Pythium species. Due to its systemic action, Fenfuram is absorbed by plant tissues and provides protective and curative effects. It is valued for its stability in soil and prolonged activity, making it suitable for use in both greenhouse and field conditions.
