Description

Diclocymet CAS NO 139920-32-4 is a systemic fungicide belonging to the cinnamic acid amide class, specifically engineered to combat rice blast disease. Its core value proposition lies in its unique mode of action, which inhibits melanin biosynthesis in the cell wall of the pathogen, offering effective control with preventative and curative properties. This product is essential for agricultural chemical manufacturers and formulators serving the global rice cultivation industry, where protecting crop yield and quality is paramount.

Application

• Primary Use in Agriculture: As a key active ingredient in fungicide formulations for the control of rice blast (*Magnaporthe grisea* or *Pyricularia oryzae*).
• Seed Treatment: Used in seed coating formulations to protect rice seedlings from early-stage blast infection.
• Foliar Application: Incorporated into suspension concentrates (SC), wettable powders (WP), or water-dispersible granules (WG) for spray application on rice paddies.
• Resistance Management: Employed in rotation or mixture with fungicides of different modes of action to manage and delay the development of pathogen resistance.
• Technical Material Supply: Supplied as a high-purity technical grade material for downstream formulation by agrochemical companies.
