  • Applications

    Fenamidone (CAS 161326-34-7) is a systemic fungicide used in crop protection to control oomycete pathogens such as Phytophthora and Pythium. It is typically applied on vegetables, fruits, and ornamentals, formulated as emulsifiable concentrates, suspension concentrates, or wettable powders for foliar sprays or soil applications. It is employed in greenhouse and field production and is commonly used in tank-mix or rotation schemes within integrated pest management to control diseases caused by oomycetes.
