  • Applications

    Bifenazate (CAS 149877-41-8) is used primarily in agriculture as an acaricide to control mite populations, notably the two-spotted spider mite, on a range of crops including fruits, vegetables, and ornamentals. It is applied in both field and greenhouse cropping systems and is commonly incorporated into integrated pest management programs to suppress mite outbreaks while allowing rotation with other chemistries. Commercial formulations include emulsifiable concentrates, suspension concentrates, and water-dispersible granules, enabling foliar spray applications and other standard spray methods. The product is typically used on crops such as grapes, citrus, apples, and ornamental plants, depending on local registration and label restrictions. Use is subject to local regulations and formulation limits.
