Description

Thiophanate-Methyl CAS NO 23564-05-8 is a broad-spectrum systemic fungicide belonging to the benzimidazole chemical class. It is a critical tool for protecting a wide range of crops from economically devastating fungal diseases by inhibiting spore germination and mycelial growth. This product is essential for agricultural producers, horticulturists, and manufacturers of crop protection formulations who require reliable and effective disease control to ensure yield and quality.

Application

• Agricultural Fungicide: Systemic control of a broad spectrum of fungal diseases, including powdery mildew, scab, leaf spot, and blight, in fruits, vegetables, cereals, and ornamentals.
• Post-Harvest Treatment: Used to prevent fungal decay and extend the shelf-life of harvested produce such as citrus fruits, bananas, and potatoes during storage and transport.
• Seed Treatment: Applied as a seed dressing to protect seedlings from soil-borne and seed-borne pathogens, promoting healthy crop establishment.
• Turf and Lawn Management: Effective in controlling dollar spot, brown patch, and other fungal diseases in golf courses, sports fields, and commercial lawns.
• Formulation Intermediate: Serves as a key active ingredient for manufacturers producing wettable powders (WP), suspension concentrates (SC), and other commercial fungicidal formulations.
• Botanical and Ornamental Protection: Used in greenhouses and nurseries to protect high-value flowers, shrubs, and trees from foliar and root diseases.
