Canada to approve Pseudomonas fluorescens strain CL145A

The Canadian Pest Management Regulatory Agency (PMRA) has proposed to approve full registration for the sale and use of Pseudomonas Fluorescens Technical and Zequanox, containing the technical grade active ingredient Pseudomonas fluorescens strain CL145A, to control dreissenid mussels (Zebra and Quagga mussels) in industrial water structures.
 
Pseudomonas fluorescens strain CL145A is a bacterium used as a microbial pest control agent (MPCA) to control dreissenid mussels (zebra and quagga mussels) and their larvae in industrial water infrastructures.

The end-use product, Zequanox, is a commercial molluscicide that contains inactivated Pseudomonas fluorescens strain CL145A as the active ingredient. Zequanox is to be used in infrastructure water in hydroelectric dams for the control of quagga and zebra mussel fouling. Application is limited to once-through water cooling systems and fire sprinklers in hydro electric dams.
