  • Applications

    Tau-Fluvalinate (CAS 102851-06-9) is a pyrethroid insecticide used in formulated products for crop protection, including field crops, fruits, vegetables, and ornamental plants, in both open-field and greenhouse cultivation. It is also applied in beekeeping to control Varroa destructor mites in honey bees through dedicated strips or formulations. In professional pest-management contexts, tau-fluvalinate may appear in formulations targeting stored-product pests and related industrial facilities, subject to local regulations and formulation limits.
