Abstract Copper based fungicides are plant protection products prevalently used in organic agriculture to control several plant diseases. Since copper can have various negative effects on the environment, the amount used should be reduced to the minimum necessary. However, this reduction should not lead to a loss of efficacy, as otherwise the quality and quantity of the yield would be at risk. During this study, a copper sulfate/copper hydroxide mixture was combined with an agent for better adhesion to grapevines. This was achieved by microencapsulation of the active agents into a fat matrix which resulted in the so called CuCaps. Laboratory analysis of dispersibility and particle size proved that CuCaps form an applicable powder, suitable for use in commercial crop protection sprayers. Field experiments demonstrated that CuCaps have an equivalent effect compared to a commercially available copper-based fungicide (CCF). Both, CuCaps and CCF were able to significantly (p

微胶囊化——一种提高铜对葡萄霜霉病的杀菌效果的创新技术

摘要 铜基杀菌剂是有机农业中普遍使用的植物保护产品，用于防治多种植物病害。由于铜会对环境产生各种负面影响，因此应将其使用量减少到必要的最低限度。然而，这种减少不应导致功效的丧失，否则产量的质量和数量将处于危险之中。在这项研究中，硫酸铜/氢氧化铜混合物与一种试剂结合，以更好地附着在葡萄藤上。这是通过将活性剂微囊化到脂肪基质中实现的，这产生了所谓的 CuCaps。分散性和粒度的实验室分析证明，CuCaps 形成适用的粉末，适用于商业作物保护喷雾器。现场实验表明，与市售的铜基杀菌剂 (CCF) 相比，CuCap 具有相同的效果。CuCaps 和 CCF 都能够显着（p
