Copper Hydroxide - an overview | ScienceDirect Topics

Copper azole is a fungicide and an insecticide. There are two types of copper azole: type A (CBA-A) and type B (CA-B). Copper boron azole type A contains the following ingredients: copper (49%), boron as boric acid (49%), and azole as tebuconazole (2%). Copper azole type B is composed of copper (96.1%) and azole as tebuconazole (3.9%) (EPA, 2011).
