Description

Validamycin CAS NO 37248-47-8 is a potent aminoglycoside antibiotic produced by *Streptomyces hygroscopicus*. It is valued for its strong and specific fungicidal activity against a range of plant pathogens, particularly those causing sheath blight and damping-off diseases. This product is essential for agricultural professionals, formulators, and researchers seeking effective, low-toxicity solutions for crop protection and plant disease management.

Application

• Agricultural Fungicide: Primary use as a systemic fungicide for controlling sheath blight in rice, damping-off in vegetables, and other fungal diseases in various crops.
• Plant Disease Management: Formulation into wettable powders, liquid concentrates, and granules for foliar application and soil drenching.
• Seed Treatment: Used as a seed coating agent to protect seedlings from soil-borne fungal pathogens during germination and early growth stages.
• Turf and Ornamental Protection: Application on golf courses, lawns, and ornamental plants to manage fungal infections like dollar spot and brown patch.
• Research & Development: Serves as a reference standard and active ingredient in agricultural research for studying antifungal mechanisms and developing new formulations.
• Integrated Pest Management (IPM): A key component in rotation programs to manage resistance and reduce reliance on high-risk chemical fungicides.

Quality Control

Our Validamycin is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for potency and purity, to ensure it meets stringent specifications for agricultural use. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, assay, and impurity profiles.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and potency.
