Description

Penflufen is a modern, systemic succinate dehydrogenase inhibitor (SDHI) fungicide belonging to the carboxamide chemical class. Its primary value lies in providing highly effective, long-lasting control against a broad spectrum of soil-borne and seed-borne fungal pathogens, protecting crop yield and quality. This product is essential for agricultural professionals and formulators seeking reliable solutions for disease management in key crops such as cereals, potatoes, and oilseed rape. Penflufen CAS NO 494793-67-8 is supplied to meet the stringent demands of the global agrochemical industry.

Application

Penflufen is utilized as a key active ingredient in modern agricultural protection strategies. Its systemic activity makes it suitable for various application methods:

• Seed Treatment: Primary use for controlling seed and soil-borne diseases like *Rhizoctonia solani*, *Fusarium* spp., and *Ustilago nuda* in cereals.
• Soil Application: Used in-furrow or as a soil drench to protect developing roots and tubers from pathogens.
• Potato Disease Control: Specifically effective against black scurf (*Rhizoctonia solani*) and silver scurf on potato seed pieces and tubers.
• Cereal Fungicide Formulations: A core component in combination products for enhanced spectrum and resistance management in wheat, barley, and rye.
• Oilseed Rape Protection: Applied for protection against damping-off and other early-season diseases.
• Professional Turf and Ornamentals: Used in specialized formulations for disease control in high-value turfgrass and ornamental plants.
