Description

Dithianon CAS NO 3347-22-6 is a quinone-based fungicide belonging to the chemical class of dithianon compounds. It matters as a broad-spectrum protective fungicide valued for its multi-site mode of action, which helps manage resistance development in fungal pathogens. This product is essential for agricultural professionals and formulators who need reliable crop protection solutions. Its primary use is in controlling a range of fungal diseases in fruit, vegetable, and ornamental crops.

Application

• Fruit Crop Protection: Control of scab (Venturia spp.) and other fungal diseases in apples and pears.
• Vineyard Management: Protective treatment against downy mildew (Plasmopara viticola) and black rot (Guignardia bidwellii) in grapes.
• Stone Fruit Cultivation: Management of shot hole disease (Wilsonomyces carpophilus) and leaf curl in peaches and cherries.
• Vegetable Farming: Application on potatoes for protection against early and late blight (Phytophthora infestans).
• Ornamental Plant Care: Fungicidal treatment in nurseries and greenhouses for disease prevention on ornamental plants.
• Agricultural Formulations: Key active ingredient in the manufacture of wettable powder (WP) and suspension concentrate (SC) fungicidal formulations.
• Integrated Pest Management (IPM): A resistance management tool used in rotation with single-site fungicides.
