After the discovery of the Bordeaux mixture, another important copper fungicide was developed: Copper Oxychloride. Around the 1950s it was patented in the United States of America. Despite almost 80 years having passed, it is still one of the main copper salts used in agriculture.
Copper oxychloride is obtained from: copper, hydrochloric acid, oxygen and water. The chemical formula is Cu₂(OH)₃Cl or CuCl₂·3Cu(OH)₂.
It is produced by the neutralization of copper chloride solutions. The industrial method starts with copper(II) chloride (CuCl₂) dissolved in water. When this acidic solution is treated with a basic reagent (such as an alkali), the pH rises and copper oxychloride precipitates as a solid. The solid is then filtered, washed and dried.
Like other copper salts, this compound protects crops against fungi and several bacteria that can damage crop health. Copper Oxychloride works by contact and is a preventive fungicide, meaning it must be applied before damage occurs.
Once applied to vegetation, it creates a protective barrier that prevents fungal spores from germinating. When fungi come into contact with copper ions, their cells are damaged and their ability to reproduce is inhibited.
Manica started producing copper oxychloride starting from copper metal in 1998. Today, the company is present on the market with many copper oxychloride formulations of which one of the most important is Ossiclor 35 WG.
Ossiclor 35 WG was registered in Italy almost 20 years ago and is still considered a very pioneering product thanks to several technical innovation features among which the green co-formulants.
The inclusion of green co-formulants extracted from wood, which are 100% environmentally friendly, provides stability to the dispersion against temperature and pH variations . Furthermore, lignosulfonates ensure better compatibility with other active substances, broadening tank-mix options with additional plant protection products and enhancing the persistence of the protective effect on crops. Thanks to its neutral pH, it can be mixed with several other fungicides and fertilizers. Our co-formulants act as natural stabilizers, helping to keep copper salt particles suspended, ensuring better shelf life and easier handling of the product and minimizing operator exposure risks.
Thanks to our co-formulants the granules of Ossiclor 35 WG disperse rapidly in water, providing excellent suspensibility and a uniform solution. Manica granules are known for their ultrafine particles and for a structure rich in cavities and channels, ensuring high dispersibility in water.
The product is also approved for organic farming, and Ossiclor 35 WG can be used throughout the entire season, from winter treatments to spring and summer applications.
