  • Applications

    Etridiazole (CAS 2593-15-9) is an agricultural fungicide active ingredient used to control oomycete diseases, notably Pythium and Phytophthora. Typical applications include seed treatment and soil drench formulations to protect a range of crops from vegetables and fruits to cereals, as well as ornamental and flowering plants. It is formulated into crop protection products for use in both greenhouse and field production, often in multi-component fungicide programs. The compound is commonly employed as an active ingredient in agricultural formulations and may be used in combination with other fungicides, subject to local regulations and formulation limits.
