  • Applications

    Hymexazol (CAS 10004-44-1) is a fungicidal active ingredient used in agriculture and horticulture to control soil- and seed-borne diseases. It is commonly formulated for seed treatments and soil drenches to protect germinating seedlings from damping-off pathogens such as Pythium and Rhizoctonia, improving crop establishment in vegetables, root crops and ornamental plants. In greenhouse and field operations, hymexazol-containing products are applied as seed coatings, transplant dips or soil applications as part of disease-management programs. It may be used in nurseries and seed production settings to reduce losses from soil-borne fungi, with uses governed by local regulatory approvals and formulation limits.
