Description

Pyriminostrobin is a modern, broad-spectrum strobilurin fungicide belonging to the methoxyacrylate class. It is valued for its systemic and protective action against a wide range of fungal pathogens in various crops. This product is essential for agricultural professionals and formulators seeking effective disease management solutions. Its unique mode of action makes it a key component in integrated pest management (IPM) and resistance management strategies.

Application

• Agricultural Fungicide: Primary use in controlling foliar and soil-borne diseases in cereals, fruits, vegetables, and specialty crops.
• Disease Management: Effective against powdery mildew, rusts, leaf spots, blights, and other economically significant fungal infections.
• Crop Protection Formulations: Used as a technical active ingredient in the manufacture of suspension concentrates (SC), wettable powders (WP), and other commercial fungicide formulations.
• Resistance Management: Employed in fungicide rotation programs to manage and delay the development of pathogen resistance.
• Post-Harvest Treatment: Potential application for protecting stored commodities from fungal decay, subject to local regulatory approvals.

Quality Control

Our Pyriminostrobin technical material is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets high-purity standards and consistent performance. Certificates of Analysis (COA) detailing assay, impurity profile, and physical properties are provided with each shipment to guarantee traceability and compliance.

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 to prevent absorption of atmospheric moisture. Keep away from heat, sparks, and open flame.
