  • Applications

    Teflubenzuron (CAS 83121-18-0) is a benzoylphenylurea insecticide that acts as a chitin synthesis inhibitor, disrupting the molting process in susceptible pests. Its real-world applications include protection of agricultural crops (row crops, fruit, and vegetables), protection of ornamental plants and horticultural crops, use in greenhouse and protected-culture settings, pest management in forests and landscape trees, and integration into IPM programs as a selective insecticide.
