Description

Fenpyrazamine CAS NO 473798-59-3 is a modern, highly effective fungicide belonging to the pyrazolinone chemical class. It matters for its unique mode of action, providing robust preventative and curative control against a range of economically significant fungal diseases, particularly powdery mildews. This product is essential for agricultural professionals and formulators seeking reliable, high-performance crop protection solutions to ensure yield and quality. Its targeted activity makes it a valuable tool in integrated pest management (IPM) programs.

Application

Fenpyrazamine is a specialized agricultural fungicide with primary and related applications including:

• Primary control of powdery mildew in various fruit, vegetable, and ornamental crops.
• Protection of cucurbits (e.g., cucumbers, melons), grapes, and strawberries from fungal infections.
• Use in fungicide resistance management programs due to its novel biochemical target.
• Formulation into suspension concentrates (SC), wettable powders (WP), and other commercial agrochemical products.
• Application via foliar spray for comprehensive plant coverage and protection.
• Research and development of new crop protection formulations and mixtures.

Quality Control

Our Fenpyrazamine technical material is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets high-purity standards for agrochemical formulation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profile, and physical properties. Our quality commitment aligns with ISO and FAO/WHO guidelines for pesticide specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. Ensure the container is kept upright to prevent leakage. Store separately from food, feed, and strong oxidizing agents.
