Description

Tolclofos-Methyl CAS NO 57018-04-9 is a systemic fungicide belonging to the organophosphate chemical class, valued for its protective and curative action against soil-borne diseases. Its primary value lies in providing reliable, long-lasting control of pathogens like *Pythium* and *Rhizoctonia*, which are major threats to crop establishment and yield. This product is essential for agricultural professionals, horticulturists, and turf managers seeking to protect seeds, seedlings, and ornamental plants from damping-off and root rot.

Application

• Seed Treatment: Applied as a coating to protect seeds from soil-borne fungal pathogens during germination and early seedling growth.
• Soil Drench Application: Used in greenhouse and nursery settings to create a protective zone around plant roots against root rot diseases.
• Ornamental and Turf Protection: Safeguards ornamental plants, lawns, and golf course turf from diseases like damping-off and brown patch.
• Agricultural Crop Protection: Employed in the cultivation of vegetables, cotton, and other field crops to ensure healthy crop establishment.
• Fungicide Formulations: Serves as a key active ingredient in the manufacturing of commercial liquid and powder fungicide formulations.
