Description

Captan is a broad-spectrum, non-systemic phthalimide fungicide widely used in agricultural and horticultural applications. Its primary value lies in its effectiveness as a protective fungicide, preventing the establishment and spread of fungal diseases on a wide variety of crops. This product is essential for agricultural producers, fruit growers, and horticulturalists seeking reliable crop protection solutions to ensure yield and quality.

Application

• Agricultural Fungicide: Used as a seed treatment to protect against soil-borne pathogens like Pythium and Rhizoctonia in crops such as cotton, soybeans, and vegetables.
• Fruit and Orchard Protection: Applied as a foliar spray to control scab, brown rot, and other fungal diseases on apples, peaches, cherries, and stone fruits.
• Ornamental and Turf Management: Protects ornamental plants, flowers, and turfgrass from a range of foliar and root diseases in landscaping and golf course maintenance.
• Post-Harvest Treatment: Used in some formulations to prevent fungal decay on fruits and vegetables during storage and transport, extending shelf life.
