Description

Metrafenone is a modern, systemic fungicide belonging to the benzophenone chemical class, valued for its unique mode of action against powdery mildew. Its primary commercial value lies in providing effective disease control with a low risk of cross-resistance, making it a crucial tool in integrated pest management (IPM) programs. This product is essential for agricultural formulators and producers serving the fruit, vegetable, and ornamental plant industries globally.

Application

• Agricultural Fungicide Formulations: A key active ingredient in suspension concentrates (SC), wettable powders (WP), and water-dispersible granules (WG) for crop protection.
• Cereal Crop Protection: Effective control of powdery mildew in wheat, barley, and other cereal grains.
• Specialty Crop Production: Management of powdery mildew in high-value crops such as grapes (viticulture), cucurbits, tomatoes, and apples.
• Ornamental and Nursery Applications: Used in greenhouse and nursery settings to protect ornamental plants and shrubs from fungal diseases.
• Integrated Pest Management (IPM): Serves as a resistance management tool when used in rotation or mixture with fungicides from other chemical classes.
• Seed Treatment: Incorporated into seed treatment formulations to provide early-season protection against soil and seed-borne pathogens.

Quality Control

Our Metrafenone technical material is manufactured under a strict quality management system to ensure batch-to-batch consistency and efficacy. Quality is verified through comprehensive analytical testing, including assay, impurity profiling, and physical property determination. A Certificate of Analysis (COA) detailing specifications and test results is provided with each shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
