EarthTec QZ is an EPA-registered molluscicide for prevention and control of quagga and zebra mussels. QZ’s unique liquid formulation is proven effective at killing adult mussels and preventing settlement and infestation by larval-stage veligers. QZ is NSF-Certified to ANSI Standard 60 for drinking water, making it an excellent approach for controlling the spread and infestation of these devastating species. EarthTec QZ can be applied in raw water intakes, lakes and reservoirs. It is a rapidly-dispersing product that is immediately bioavailable. The zebra mussels do not detect a threat and readily ingest the QZ. Studies have confirmed complete mortality within a 48-96 hour period of time. It has also shown to be effective at concentrations that are safe for most fish and other non-target organisms. Contact SOLitude Lake Management for pricing and application services.
