Overview
Flusilazole is a triazole-based fungicide developed for agricultural use to combat a wide range of fungal pathogens. It belongs to the sterol biosynthesis inhibitor (SBI) class, disrupting ergosterol production in fungi, which is essential for their cell membrane integrity. Its systemic action allows it to be absorbed by plants, providing long-lasting protection. Introduced in the 1980s, flusilazole has become a staple in integrated pest management (IPM) programs due to its efficacy and relatively low environmental persistence compared to older fungicides. It is commonly formulated as emulsifiable concentrates or wettable powders for easy application.
Physical and Chemical Properties
Flusilazole is a white crystalline solid with a molecular weight of 315.4 g/mol and a density of 1.3 g/cm³. It melts at 53-55°C and is slightly soluble in water but readily dissolves in organic solvents like acetone and methanol. These properties make it suitable for formulation into various agricultural products. The compound is stable under normal storage conditions but may degrade when exposed to strong acids or bases. Its low volatility reduces the risk of airborne contamination, but proper handling is still required to avoid health hazards.
Main Applications
Flusilazole is primarily used to control fungal diseases such as powdery mildew, rusts, and leaf spots in crops like wheat, barley, grapes, and pome fruits. Its systemic nature ensures protection even in untreated plant parts, making it highly effective for foliar applications. In addition to field crops, flusilazole is used in horticulture and viticulture to maintain yield and quality. It is often applied preventively or at the first signs of infection, with recommended dosages varying by crop and disease pressure. Resistance management strategies, such as rotating with other fungicide classes, are advised to prolong its effectiveness.
Safety and Storage
Flusilazole is classified as harmful if swallowed and can cause skin and eye irritation. Personal protective equipment (PPE), including gloves and goggles, is mandatory during handling. In case of exposure, rinse affected areas immediately and seek medical advice if symptoms persist. Storage should be in a cool, dry place away from direct sunlight and incompatible materials like strong oxidizers. Containers must be tightly sealed to prevent moisture absorption and contamination. Disposal should comply with local environmental regulations to minimize ecological impact.
B2B Procurement Guide
When procuring flusilazole, verify the supplier’s certifications and adherence to regulatory standards such as EPA or EU approvals. Key factors include purity (typically 95-98%), formulation type (e.g., EC or WP), and batch consistency. Request safety data sheets (SDS) and technical specifications before purchase. Bulk buyers should negotiate pricing based on volume, with reference prices ranging from $20-$50 per kg. Consider logistical factors like packaging (drums vs. bags) and lead times to align with seasonal demand. Establish long-term contracts with reliable suppliers to ensure steady supply and quality assurance.
