Description

Pyrifenox is a systemic fungicide belonging to the pyrimidine chemical class, widely recognized for its protective and curative action against a range of fungal diseases. Its primary value lies in its effectiveness in controlling powdery mildews and other economically significant pathogens in agricultural settings. This product is essential for professional growers, agricultural formulators, and agrochemical companies seeking reliable crop protection solutions to ensure yield and quality. Pyrifenox CAS NO 88283-41-4 is a key active ingredient for the development of modern, high-performance fungicidal formulations.

Application

Pyrifenox is utilized across various agricultural sectors for its robust fungicidal properties. Key application scenarios include:

• Control of Powdery Mildew in high-value crops such as grapes, cucurbits, and ornamentals.
• Fungicidal Formulation as a key technical-grade active ingredient for manufacturing wettable powders (WP), suspension concentrates (SC), and emulsifiable concentrates (EC).
• Integrated Pest Management (IPM) Programs, where it is used in rotation with other fungicide classes to manage resistance.
• Protection of Cereal Crops against specific foliar diseases, contributing to improved grain quality.
• Greenhouse and Nursery Applications for the protection of vegetables and ornamental plants.
• Post-Harvest Treatment protocols for certain fruits to extend shelf life and reduce spoilage.

Quality Control

Our Pyrifenox is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to meet technical-grade specifications. A Certificate of Analysis (COA) detailing all quality 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 area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
