  • Applications

    Cyproconazole (CAS 94361-06-5) is a systemic azole fungicide used primarily in agriculture to protect crops against fungal diseases; it is commonly formulated for use on cereals (wheat, barley), fruits (grapes, apples), vegetables (tomatoes, cucumbers), and ornamental plants, as well as turf, providing control of powdery mildew and other fungal pathogens while supporting crop health and yield.
