Overview
Vinclozolin is a systemic dicarboximide fungicide developed for agricultural use. It was first introduced in the 1980s and has been widely used to control fungal pathogens in various crops. The compound works by inhibiting spore germination and mycelial growth, making it effective against diseases like gray mold and white rot. As a selective fungicide, vinclozolin is primarily used in vineyards, fruit orchards, and vegetable production. Its chemical stability and low solubility in water contribute to its persistence in the environment, which has led to regulatory scrutiny in some regions.
Physical and Chemical Properties
Vinclozolin presents as a white to off-white crystalline solid with a molecular weight of 286.11 g/mol. It has a density of 1.51 g/cm³ and melts at 108°C. The compound is characterized by low water solubility (14 mg/L at 20°C) but demonstrates good solubility in many organic solvents including acetone and dichloromethane. The chemical stability of vinclozolin under normal storage conditions makes it suitable for agricultural formulations. However, it may decompose when exposed to strong acids or bases, and its stability decreases at higher temperatures.
Main Applications
Vinclozolin finds its primary application in protecting crops from fungal diseases, particularly in vineyards where it controls Botrytis cinerea (gray mold). It's also effective against Sclerotinia sclerotiorum in vegetables and Monilia species in stone fruits. The fungicide is typically applied as a foliar spray during vulnerable growth stages. In addition to agricultural uses, vinclozolin has been employed in turf management and ornamental plant protection. Its systemic action allows for both protective and curative effects, though resistance management strategies should be implemented to maintain efficacy.
Safety and Storage
Vinclozolin requires careful handling due to its potential endocrine-disrupting properties. Workers should use appropriate personal protective equipment including gloves, goggles, and respiratory protection when handling concentrated forms. The compound should be stored in original containers in cool, dry conditions away from food and feed. Regulatory status varies by region, with some countries restricting or banning its use due to environmental concerns. Proper disposal methods must be followed, and spillage should be contained to prevent environmental contamination. Always consult local regulations before use or disposal.
B2B Procurement Guide
When procuring vinclozolin for commercial use, buyers should first verify the legal status of the compound in their target markets. Key specifications to request include purity level (typically 95-98%), formulation type (wettable powder or suspension concentrate), and batch analysis certificates. Quality suppliers should provide comprehensive safety data sheets and technical support. Bulk purchases often offer cost advantages, but storage capacity and shelf life considerations must be accounted for. Lead times may vary depending on regional production and regulatory requirements.
