Copper 2+, the cupric ion
Thanks to its unique formulation, the copper in EarthTec and EarthTec QZ is kept entirely in the cupric ion form – the only biologically active form of copper – and it therefore works at a significantly lower copper dose than copper sulfate or chelated copper products. There is virtually no waste or loss to precipitation or settling, and for that reason we believe EarthTec is the most environmentally responsible way to apply copper for pest control.
