Introduction

Cyprodinil 98% TC is a highly effective, systemic fungicide belonging to the anilinopyrimidine class, widely used for controlling fungal diseases in fruits, vegetables, and cereals. It acts primarily by inhibiting methionine biosynthesis in pathogenic fungi, which interferes with protein production and blocks fungal growth and infection processes.

This technical grade material appears as a white to off-white crystalline solid and is designed for industrial formulation into various crop protection products. Cyprodinil provides preventive and curative activity, strong penetration into plant tissues, and reliable disease control under diverse climatic conditions.

Thanks to its unique mode of action and strong compatibility with other fungicides, Cyprodinil plays an important role in modern integrated disease management and resistance management programs. The 98% TC grade is mainly used by formulation companies to produce products such as water-dispersible granules (WDG), suspension concentrates (SC), and wettable powders (WP).

Product Feature and Application

As a 98% technical concentrate, Cyprodinil demonstrates strong preventive and curative fungicidal activity with systemic and translaminar movement within plant tissues. Its mode of action involves inhibiting methionine biosynthesis in fungi, which disrupts protein formation and suppresses pathogen growth and infection.

Cyprodinil is widely used to control key diseases such as gray mold in grapes and strawberries, apple scab, and various fruit rot diseases. Typical application rates range from 300–750 g/ha, depending on crop and disease pressure.

The product is suitable for stand-alone use or mixture with other fungicides, such as strobilurins or triazoles, to broaden the disease spectrum and enhance resistance management strategies.

The 98% TC material is primarily intended for formulation into end-use products including:WDG (Water-Dispersible Granules),SC (Suspension Concentrate),WP (Wettable Powder). Its stable chemical properties, good compatibility, and processing adaptability make it an excellent raw material for modern fungicide formulations.
