Overview
Etoxazole is a selective acaricide belonging to the oxazoline chemical class. It is widely used in agriculture for its effectiveness against various mite species, including spider mites and rust mites. The compound works by inhibiting the molting process of mites, leading to their eventual death. Its selective action minimizes harm to beneficial insects, making it a preferred choice in integrated pest management systems. Developed in the 1990s, etoxazole has gained popularity due to its long residual activity and low toxicity to mammals. It is commonly applied to crops such as citrus, apples, grapes, and vegetables. The chemical's stability under various environmental conditions further enhances its utility in diverse agricultural settings.
Physical and Chemical Properties
Etoxazole is a white to off-white crystalline solid with a molecular weight of 359.41 g/mol. It has a density of 1.18 g/cm³ and a melting point range of 101-102°C. The compound is practically insoluble in water but readily dissolves in organic solvents like acetone and methanol. Its chemical stability is notable, with minimal degradation under normal storage conditions. Etoxazole exhibits low volatility, reducing the risk of airborne exposure during handling. The compound's partition coefficient (log P) of 4.5 indicates strong lipophilicity, which contributes to its effective penetration through mite cuticles.
Main Applications
Etoxazole is primarily used in agriculture for controlling phytophagous mites that damage crops. It shows particular efficacy against Tetranychus and Panonychus species, common pests in fruit orchards and vineyards. The acaricide is typically applied as a foliar spray, with recommended application rates varying between 50-100 g/ha depending on the crop and infestation severity. In addition to its use in conventional farming, etoxazole finds application in greenhouse production systems. Its compatibility with integrated pest management programs stems from its selectivity, which preserves populations of predatory mites and other beneficial organisms. Some formulations combine etoxazole with other acaricides to enhance spectrum and resistance management.
Safety and Storage
Etoxazole is classified as harmful if swallowed and may cause skin and eye irritation. Proper personal protective equipment, including gloves and goggles, should be worn during handling. In case of exposure, affected areas should be rinsed immediately with plenty of water. The compound should be stored in its original container in a cool, dry, well-ventilated area away from food and feed. Storage temperatures should not exceed 30°C to maintain product integrity. Containers must be kept tightly closed when not in use to prevent contamination and moisture absorption.
B2B Procurement Guide
When procuring etoxazole, buyers should verify the supplier's certification and compliance with relevant agricultural chemical regulations. Technical-grade material typically has a purity of 95-98%, with price variations based on quantity and packaging specifications. Bulk purchases (100+ kg) generally offer cost advantages, with prices commonly ranging from $50-100 per kg. Request certificates of analysis to confirm product specifications and ensure batch-to-batch consistency. Consider suppliers who provide technical support and proper documentation, including material safety data sheets and application guidelines.
