Zequanox: The Industry’s Only Biopesticide for Invasive Mussel Control
Environmentally friendly• Derived from soil microbe Pseudomonas
fluorescens– Present in all natural water bodies– Used in production of food product (cheese
product) and present in yoghurt – High concentrations present in your refrigerator– Composed of 50% dead cells and 50% food-grade
inert ingredients
EPA-registered, tolerance exempt (residues are not of toxicological concern)• Approved for all food and non-food uses,
including uses that result in direct or incidental contact with food, food-contact materials/equipment, irrigation and drinking source water

Fermentation Raw Materials
Raw Materials are Batched and Sterilized
Sterile Fermentation
Concentration (e.g, centrifuge, fluidized bed)
Batching with concentrated cells and inert ingredients
Spry Drying-Heat kills cells Packaging
Specifications require food grade
QC testing of post batching and sterilization
QC of HarvestDesigned to specifically grow Pf CL 145
QC on concentrated cells
QC on concentrated cells
QC on final productMinimally includes;-Pathogen testing-Viable cell count
Manufacture at food grade facilities (some Kosher)
Zequanox – possible uses in infested systems
Storage and stabilization basins (NSF60 often required) Large transmission systems - canals, pipelines (NSF60 required) Reservoirs and Lakes (NSF60 often required)
- No EPA water quality limit for drinking water (e.g. copper)- Will not kill stocked fish
Intake structures (NSF60 required)- Will not produce disinfection by-products in raw water
- Will not contribute residual copper to raw water
X Not labeled or intended for direct application to treated drinking water (zebra mussels do not occur in chlorinated systems)
X Can not be combined with other chemical treatmentsPage 7
