Overview
Propiconazole is a triazole fungicide widely used in agriculture to control fungal diseases. It belongs to the demethylation inhibitor (DMI) class, which disrupts fungal cell membrane synthesis. This chemical is valued for its systemic action, meaning it is absorbed and distributed within the plant, providing long-lasting protection. First introduced in the 1980s, propiconazole has become a staple in crop protection programs. It is effective against a broad range of pathogens, including rusts, leaf spots, and powdery mildew. Its versatility makes it suitable for use on cereals, fruits, and turf, among other crops.
Physical and Chemical Properties
Propiconazole is a pale yellow viscous liquid with a molecular weight of 342.22 g/mol. It is soluble in organic solvents like acetone and methanol but has limited solubility in water. The chemical has a density of 1.27 g/cm³ and is stable under normal storage conditions. Its systemic nature allows it to be absorbed by plants and translocated to growing tissues, providing internal protection. The fungicide works by inhibiting the biosynthesis of ergosterol, a key component of fungal cell membranes, leading to cell death.
Main Applications
Propiconazole is primarily used in agriculture to protect crops from fungal infections. It is commonly applied to cereals such as wheat and barley to control rusts and leaf spots. In fruit cultivation, it helps manage powdery mildew and other fungal diseases. The chemical is also used in turf management to maintain healthy grass in golf courses and sports fields. Its broad-spectrum activity and long residual effect make it a preferred choice for integrated pest management programs.
Safety and Storage
Propiconazole is classified as toxic if ingested or inhaled, and it can cause skin and eye irritation. Proper protective equipment, including gloves and goggles, should be worn during handling. Storage should be in a cool, dry place away from direct sunlight and moisture to maintain stability. Disposal must comply with local regulations to prevent environmental contamination. The chemical should be kept out of reach of children and animals, and spills should be cleaned up immediately using appropriate absorbent materials.
B2B Procurement Guide
When procuring propiconazole, buyers should verify the CAS number (60207-90-1) to ensure product authenticity. Purity levels, typically ranging from 95% to 98%, should be confirmed through supplier documentation. It is advisable to source from certified suppliers with a track record of quality and reliability. Bulk purchases may offer cost advantages, but storage capacity and shelf life should be considered. Buyers should also check for compliance with regional agricultural regulations and ensure proper labeling and safety data sheets are provided.
