Description

Coumoxystrobin CAS NO 850881-70-8 is a modern, broad-spectrum agricultural fungicide belonging to the strobilurin chemical class. It matters for its systemic and protective action, effectively controlling a wide range of fungal pathogens that threaten crop yield and quality. This product is essential for agricultural formulators and producers seeking advanced crop protection solutions for fruits, vegetables, cereals, and other high-value crops.

Application

• Agricultural Fungicide Formulations: Primary active ingredient in suspension concentrates (SC), emulsifiable concentrates (EC), and water-dispersible granules (WG) for foliar application.
• Control of Powdery Mildew: Effective against powdery mildew in crops such as cucurbits, grapes, and ornamentals.
• Control of Rust Diseases: Management of various rust pathogens affecting cereals, soybeans, and other field crops.
• Control of Leaf Spot Diseases: Protection against Septoria, Alternaria, and other leaf-spotting fungi in vegetables and field crops.
• Fruit Disease Management: Used in programs to control scab, botrytis, and other fungal diseases in pome fruits, stone fruits, and berries.
• Seed Treatment: Component in advanced seed treatment formulations to protect seedlings from soil and seed-borne diseases.
• Resistance Management: Valuable tool in fungicide rotation programs to manage and delay the development of pathogen resistance.
