About EarthTec Qz
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.
Low doses of EarthTec QZ ionic copper used in effort to eradicate quagga mussels from an entire Pennsylvania lake
This report describes the use of the acid-stabilized ionic copper formulation called EarthTec QZ to treat an entire lake heavily infested with quagga mussels for the purpose of eradicating the invasive species. This is the first recorded instance of a lake-wide eradication effort of quagga mussels and is also the largest and deepest lake known to have been the subject of an effort to completely eradicate either quagga or zebra mussels.
In a notably successful campaign against a troublesome invasive species, Fish and Wildlife Service officials today are applauding the eradication of a dinner plate-sized foreign intruder from New Jersey ponds.
Invasive mussel control will be a key topic at the upcoming NALMS symposium in Burlington, Vermont. The event will feature a tour of the city’s . . .
