Description

Spiromesifen is a highly effective insecticide and acaricide belonging to the chemical class of tetronic acid derivatives. It is valued for its unique mode of action, providing robust control against a wide range of mite and insect pests, including those resistant to other chemistries. This product is essential for agricultural professionals and formulators seeking reliable crop protection solutions. Spiromesifen CAS NO 283594-90-1 is a key active ingredient in integrated pest management (IPM) programs globally.

Application

Spiromesifen is a versatile active ingredient with broad-spectrum activity, primarily used in the following scenarios:

• Agricultural Crop Protection: Control of whiteflies, spider mites (e.g., two-spotted spider mite), and other sucking pests in crops such as cotton, vegetables, ornamentals, and fruits.
• Professional Pest Management: Formulation into products for use in greenhouse and nursery operations to protect high-value plants.
• Resistance Management: A critical tool in rotation or mixture with other insecticide classes to mitigate and manage pest resistance.
• Technical Material for Formulation: Sourced by agrochemical companies for the manufacture of emulsifiable concentrates (EC), suspension concentrates (SC), and other end-use formulations.
• Ornamental and Floriculture: Protection of ornamental plants and cut flowers from damaging mite infestations.
