Description

Fenaminstrobin CAS NO 366815-39-6 is a modern, broad-spectrum strobilurin fungicide belonging to the methoxyacrylate class. It matters for its unique dual-action mechanism, offering both protective and curative activity against a wide range of economically significant fungal pathogens in agriculture. This product is essential for agricultural chemical manufacturers, formulators, and research institutions developing next-generation crop protection solutions to enhance yield and food security.

Application

• Agricultural Fungicide Formulations: Primary active ingredient in suspension concentrates (SC), emulsifiable concentrates (EC), and water-dispersible granules (WG) for foliar application.
• Cereal Crop Protection: Effective against diseases like Septoria leaf blotch, powdery mildew, and rusts in wheat, barley, and other cereals.
• Fruit and Vegetable Disease Management: Controls powdery mildew, downy mildew, and early blight in crops such as grapes, tomatoes, cucurbits, and potatoes.
• Rice Disease Control: Used to manage sheath blight (Rhizoctonia solani) and blast (Magnaporthe grisea) in paddy rice.
• Seed Treatment: Incorporated into seed coating formulations to protect seedlings from soil-borne and seed-borne fungal infections.
• Resistance Management Programs: A key component in fungicide rotation and mixture strategies to delay the development of pathogen resistance.
• Technical-Grade Material: Serves as the high-purity intermediate for the synthesis of various commercial end-use formulations.
