Description

Tetradifon is a highly effective and selective acaricide belonging to the chemical class of sulfones. This compound is valued for its long-lasting residual activity and effectiveness against a broad spectrum of mite species, particularly those resistant to other chemical classes. It is primarily utilized in agricultural and horticultural sectors for integrated pest management programs. Global buyers rely on our supply for consistent quality and reliable performance in demanding crop protection applications.

Application

• Agricultural Acaricide: Control of phytophagous mites, including spider mites (Tetranychus spp.) and rust mites, in crops such as citrus fruits, grapes, apples, and ornamentals.
• Horticultural Pest Management: Protection of greenhouse plants and nursery stock from mite infestations, often used in rotation with other miticides to manage resistance.
• Public Health Vector Control: Potential use in formulations for controlling mites of public health importance in specific regional programs.
• Animal Husbandry: Historically used in some regions for controlling parasitic mites on livestock, though regulations vary.
• Research & Development: Serves as a reference standard and active ingredient for developing new formulations and efficacy studies in agrochemical research.
