Description

Pyrisoxazole is a highly effective systemic fungicide belonging to the chemical class of succinate dehydrogenase inhibitors (SDHIs). It matters for its targeted action against a broad spectrum of fungal pathogens, particularly those causing gray mold and powdery mildew, offering reliable crop protection. This product is essential for agricultural professionals and formulators in the agrochemical industry seeking advanced solutions for fruit, vegetable, and ornamental crop management.

Application

• Agricultural Fungicide: Primary use for the control of Botrytis cinerea (gray mold) and powdery mildew in high-value crops such as grapes, strawberries, and tomatoes.
• Seed Treatment: Applied as a seed dressing to protect against soil-borne and seed-borne fungal diseases during germination and early plant development.
• Post-Harvest Protection: Used in treatment protocols to prevent fungal decay of fruits and vegetables during storage and transport, extending shelf life.
• Ornamental and Turf Management: Effective in protecting ornamental plants, flowers, and turfgrass from destructive fungal infections in commercial landscaping and horticulture.
• Formulation Intermediate: Serves as a key technical-grade active ingredient for the manufacturing of various commercial fungicidal formulations, including wettable powders (WP) and suspension concentrates (SC).
• Integrated Pest Management (IPM) Programs: A valuable component in resistance management strategies, often used in rotation with fungicides of different modes of action.

Quality Control

Our Pyrisoxazole is manufactured under strict quality management systems to ensure batch-to-batch consistency and high efficacy. The product undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to meet technical-grade specifications. A Certificate of Analysis (COA) detailing purity, relevant impurities, and physical parameters 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 each use to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
