Overview
Fluazinam is a synthetic fungicide belonging to the chemical class of pyridinamines. It was developed to combat a wide range of fungal pathogens affecting agricultural crops. The compound is particularly effective against oomycetes, such as those causing late blight in potatoes and tomatoes. Fluazinam's unique mode of action involves the inhibition of fungal mitochondrial respiration, disrupting energy production in the pathogen. This makes it a valuable tool for resistance management in integrated pest control programs. The chemical is registered for use in many countries, subject to local agricultural regulations.
Physical and Chemical Properties
Fluazinam presents as a yellow crystalline powder at room temperature, with limited water solubility but good solubility in many organic solvents. Its molecular structure contains chlorine and fluorine atoms, contributing to its stability and fungicidal activity. The compound demonstrates good thermal stability under normal storage conditions. Its melting point ranges between 115-117°C, while its vapor pressure is relatively low, reducing volatility concerns during application. These properties make fluazinam suitable for various formulation types, including wettable powders and suspension concentrates.
Main Applications
Fluazinam is primarily used in agriculture to protect crops from fungal diseases. It shows exceptional efficacy against potato late blight (Phytophthora infestans) and grapevine downy mildew (Plasmopara viticola), among other pathogens. Application typically occurs as a foliar spray, with recommended doses varying by crop and disease pressure. The fungicide is often used in rotation with other fungicide classes to prevent resistance development. Some formulations combine fluazinam with other active ingredients for broader spectrum control or enhanced systemic activity.
Safety and Storage
As with many agricultural chemicals, proper handling of fluazinam requires precautions. Workers should wear gloves, protective clothing, and eye protection when handling the concentrate. Adequate ventilation is recommended during mixing and application. Storage should be in original containers, tightly sealed, and separated from foodstuffs and animal feed. The chemical is stable under normal conditions but should be protected from extreme temperatures and moisture. Spill procedures include containment with inert material and disposal according to local regulations.
B2B Procurement Guide
When procuring fluazinam for commercial use, buyers should verify the product's registration status in their target market. Technical-grade material typically ranges from 95-98% purity, with specifications varying by supplier. Reliable suppliers should provide certificates of analysis, material safety data sheets, and proof of regulatory compliance. Bulk purchases may qualify for discounts, but storage capacity and product shelf life should be considered. Transportation typically requires hazardous materials handling certification for larger quantities.
