Description

Polyoxin L is a nucleoside antibiotic complex produced by *Streptomyces cacaoi* var. *asoensis*, known for its specific fungicidal activity. This compound is valued for its unique mode of action, inhibiting chitin synthesis in fungal cell walls, which makes it an effective tool for managing resistant pathogens. It is primarily required by the agricultural sector for crop protection and by research institutions studying novel antifungal mechanisms and developing sustainable biocontrol solutions.

Application

• Agricultural Fungicide: Used to control a range of fungal diseases, particularly rice sheath blight, in integrated pest management (IPM) programs.
• Horticulture & Turf Management: Applied for disease control in fruits, vegetables, and ornamental plants, as well as on golf courses and lawns.
• Post-Harvest Treatment: Helps prevent fungal decay during the storage and transportation of produce.
• Research & Development: Serves as a critical reference standard and active ingredient in antifungal research and the development of new agrochemical formulations.
• Biocontrol Agent Formulation: A key component in environmentally friendly bio-pesticides and organic farming solutions.

Quality Control

Our Polyoxin L is manufactured under strict quality management systems to ensure batch-to-batch consistency and efficacy. Each lot is subjected to comprehensive analytical testing, including identity confirmation, potency assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
