Description

Chlorothalonil is a broad-spectrum, non-systemic organochlorine fungicide widely recognized for its protective action against a vast array of fungal pathogens. Its primary value lies in providing reliable, long-lasting control of foliar and fruit diseases, making it a cornerstone in integrated pest management programs. This compound is essential for agricultural professionals, horticulturists, and manufacturers of crop protection formulations targeting high-value fruits, vegetables, turf, and ornamental plants.

Application

• Agricultural Fungicide: Protective control of foliar diseases such as early and late blight in potatoes and tomatoes, leaf spot in peanuts and celery, and downy mildew in various crops.
• Turf and Ornamental Management: Used on golf courses, lawns, and in nurseries to manage diseases like dollar spot, brown patch, and anthracnose.
• Fruit and Vineyard Protection: Application on grapes, citrus, and other fruits to combat Botrytis, black rot, and scab diseases.
• Vegetable Crop Protection: Key for disease control programs in brassicas, cucurbits, and leafy greens against pathogens like Alternaria and Sclerotinia.
• Industrial Preservative: Used in certain paints, coatings, and adhesives as a fungicidal additive to prevent mold and mildew growth.
• Formulation Ingredient: Serves as the active technical material for manufacturing wettable powders (WP), suspension concentrates (SC), and other commercial fungicidal formulations.
