Hymexazol is widely used as a fungicide in agriculture, particularly for seed treatment and soil application to protect crops from fungal infections. It is effective against soil-borne pathogens such as Fusarium and Pythium, which commonly affect vegetables, fruits, and ornamental plants. Additionally, it is used in hydroponic systems to prevent root rot and other fungal diseases. Hymexazol also promotes healthy root development, enhancing plant growth and yield. Its application is common in rice paddies to control seedling blight and in greenhouse cultivation to maintain plant health.
