Description

Polyoxin CAS NO 11113-80-7 is a nucleoside antibiotic complex produced by *Streptomyces cacaoi* var. *asoensis*, known for its potent and specific fungicidal activity. Its primary value lies in its unique mode of action, inhibiting chitin synthesis in fungal cell walls, making it a critical tool for managing resistant pathogens. This product is essential for agricultural research and formulation, serving professionals in the crop protection, specialty chemical, and agrochemical industries who require reliable, high-purity active ingredients.

Application

• Agricultural Fungicide Formulation: Core active ingredient in foliar sprays and systemic treatments for controlling a wide range of fungal diseases in fruits, vegetables, and ornamental plants.
• Disease Management in High-Value Crops: Particularly effective against pathogens like *Alternaria*, *Botrytis*, and *Cochliobolus* in settings such as vineyards, orchards, and greenhouse cultivation.
• Integrated Pest Management (IPM) Programs: Valued for its low toxicity to non-target organisms, making it suitable for rotation in resistance management strategies.
• Research & Development: Used as a biochemical standard and reference material in antimicrobial research, mode-of-action studies, and the development of new agrochemical products.
• Post-Harvest Treatment: Application in solutions or coatings to prevent fungal decay during the storage and transport of produce.
• Turf and Lawn Care: Component in professional formulations for managing dollar spot, brown patch, and other turfgrass diseases.

Quality Control

Our Polyoxin is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high biological activity. Quality is verified through comprehensive analytical methods including HPLC for assay and impurity profiling. A Certificate of Analysis (COA) detailing purity, potency, and relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed and under dry conditions to prevent degradation. Keep away from incompatible materials.
