Description

Polyoxin D is a nucleoside antibiotic fungicide derived from *Streptomyces cacaoi* var. *asoensis*. This compound is valued for its unique mode of action, specifically inhibiting chitin synthase, which makes it a critical tool for managing fungal diseases in agriculture and horticulture. It is primarily sought by professionals in the crop protection, specialty chemical, and research sectors for developing effective and environmentally responsible fungicidal formulations.

Application

• Agricultural Fungicide: Core component in formulations for controlling a wide range of fungal diseases, particularly those caused by Ascomycetes and Deuteromycetes, such as powdery mildew, gray mold (*Botrytis cinerea*), and sheath blight in various crops.
• Horticulture and Turf Management: Used in professional landscaping, greenhouse operations, and turf management for disease prevention on ornamental plants, fruits, and vegetables.
• Integrated Pest Management (IPM): Serves as a key rotation partner in resistance management programs due to its distinct biochemical target, helping to prolong the efficacy of other fungicide classes.
• Research & Development: Employed as a biochemical standard and tool in agricultural research for studying chitin biosynthesis and developing novel antifungal agents.
• Post-Harvest Treatment: Applied to protect fruits and vegetables from fungal decay during storage and transport.
• Seed Treatment: Used to coat seeds, providing systemic protection against soil-borne and early-season fungal pathogens.
