Description

Cyenopyrafen is a highly effective acaricide belonging to the pyrazole chemical class, specifically developed for superior mite control. Its unique mode of action, targeting mitochondrial complex II, provides robust and long-lasting efficacy against a broad spectrum of pest mites, including those resistant to other chemistries. This product is essential for agricultural professionals and formulators seeking reliable, advanced solutions for integrated pest management (IPM) programs in high-value crops globally.

Application

Cyenopyrafen CAS NO 560121-52-0 is a cornerstone active ingredient for modern agricultural and specialty pest control. Its primary and related applications include:

• Agricultural Crop Protection: Control of spider mites (Tetranychus spp.), rust mites, and other phytophagous mites in fruits (e.g., citrus, pome fruits, grapes), vegetables, and ornamental plants.
• Resistance Management: A key component in rotation programs to mitigate and manage resistance in mite populations to other acaricide classes.
• Professional Horticulture and Floriculture: Protection of greenhouse and nursery crops from mite infestations that can cause significant aesthetic and economic damage.
• Formulation Intermediate: Used by agrochemical companies as a technical-grade active ingredient for the production of various end-use formulations such as suspension concentrates (SC) and wettable powders (WP).
• Integrated Pest Management (IPM): Valued for its favorable selectivity profile, making it suitable for use in IPM systems alongside biological control agents.
