Overview
Cyproconazole is a triazole-class fungicide developed for agricultural use to combat a wide range of fungal pathogens. It is particularly effective against diseases like rusts, powdery mildews, and leaf spots in crops such as wheat, barley, and soybeans. The compound works by inhibiting ergosterol biosynthesis, which is essential for fungal cell membrane formation. First introduced in the late 1980s, cyproconazole has become a key tool in integrated pest management (IPM) programs. Its systemic action allows it to be absorbed by plants, providing long-lasting protection. The chemical is available in various formulations, including wettable powders and liquid concentrates, to suit different application methods.
Physical and Chemical Properties
Cyproconazole is a white to light brown crystalline powder with a melting point of 106-108°C. It is moderately soluble in water but highly soluble in organic solvents like acetone and methanol. The compound is stable under normal storage conditions but may degrade when exposed to strong acids or bases. The molecular weight of cyproconazole is 291.78 g/mol, and its chemical structure includes a triazole ring, which is responsible for its fungicidal activity. The compound's stability and solubility profile make it suitable for various formulation types, including emulsifiable concentrates and seed treatments.
Main Applications
Cyproconazole is primarily used in agriculture to protect crops from fungal infections. It is applied to cereals like wheat and barley to control diseases such as leaf rust and powdery mildew. The fungicide is also used in vineyards, orchards, and vegetable fields to manage fungal pathogens that affect yield and quality. In addition to its agricultural uses, cyproconazole is sometimes employed in turf management to protect grasses from fungal diseases. Its systemic nature allows for flexible application methods, including foliar sprays and seed treatments, making it a versatile option for farmers and agronomists.
Safety and Storage
Cyproconazole is classified as a hazardous chemical and requires careful handling. Protective clothing, gloves, and eye protection should be worn during application to avoid skin contact or inhalation. In case of exposure, rinse affected areas with plenty of water and seek medical attention if necessary. Storage conditions are critical to maintaining the chemical's efficacy. Cyproconazole should be kept in a cool, dry place away from direct sunlight and moisture. Containers must be tightly sealed to prevent contamination and degradation. Proper disposal methods should be followed to minimize environmental impact.
B2B Procurement Guide
When procuring cyproconazole, B2B buyers should verify the CAS number (94361-06-5) to ensure they are purchasing the correct chemical. Purity levels should also be confirmed, as they can affect the product's performance. Suppliers should provide certificates of analysis and comply with local regulatory requirements. Price ranges for cyproconazole vary depending on quantity and purity, typically falling between $50 and $100 per kilogram. Buyers should consider bulk purchasing options to reduce costs but ensure proper storage facilities are available. It is advisable to source from reputable suppliers with a track record of quality and reliability.
