Copper oxychloride
Description
Copper oxychloride (CAS 1332-65-6), also known as copper chloride hydroxide, is an inorganic copper salt used commercially as a contact fungicide and bactericide. It delivers broad-spectrum antimicrobial activity across agricultural and industrial applications where copper-based protection is required.
In crop protection, this compound is formulated into wettable powders and suspension concentrates to control fungal and bacterial diseases in fruits, vegetables, vines, and cereals. This includes effective management of downy mildew, blight, and leaf spot pathogens.
Ornamental horticulture and forestry operations use it to protect nursery stock and timber against bacterial canker and fungal rots. In water treatment, it functions as an algaecide and microbial control agent in reservoirs and irrigation systems.
The material is also utilized in industrial cooling circuits to maintain system hygiene. It frequently appears in antifouling coatings and wood preservative formulations where sustained copper release is needed for long-term protection.
Copper oxychloride is supplied as a green-blue technical powder, with wettable powder and water-dispersible granule forms common in the agrochemical trade. These formats ensure ease of application and stability during storage.
Standard technical grades are specified by copper content, typically expressed as metallic copper equivalent. Buyers sourcing for formulation should confirm particle size distribution and copper assay against relevant industrial specifications.
