Description

Cyprodinil is a modern, broad-spectrum anilinopyrimidine fungicide that provides effective control against a wide range of plant pathogens. Its primary value lies in its unique mode of action, which inhibits methionine biosynthesis and offers preventative, curative, and translaminar activity. This makes it a critical tool for agricultural professionals and formulators seeking reliable disease management solutions to protect crop yield and quality.

Application

Cyprodinil is a versatile fungicide active ingredient used in various agricultural and horticultural settings. Its primary applications include:

• Cereal Crop Protection: Control of key diseases such as eyespot (Oculimacula spp.), Septoria leaf blotch, and powdery mildew in wheat and barley.
• Fruit and Vine Management: Effective against Botrytis bunch rot (gray mold) and powdery mildew in grapes, stone fruits, and strawberries.
• Vegetable and Ornamental Production: Management of Alternaria leaf spots, Botrytis, and other foliar diseases in a wide range of high-value crops.
• Seed Treatment Formulations: Used as a component in seed treatment products to protect seedlings from soil and seed-borne diseases.
• Agricultural Formulations: Serves as a technical-grade active ingredient for the manufacture of suspension concentrates (SC), wettable granules (WG), and other commercial fungicide formulations.
• Resistance Management Programs: Valued for its distinct biochemical target site, it is a key component in fungicide rotation and mixture strategies to delay the development of pathogen resistance.
