Bubble Curtains Eurasian Water Milfoil Control with ProcellaCOR FX
ProcellaCOR FX: A New Selective Option for Eurasian Watermilfoil Control in Québec
A selective, ultra-low-dose treatment option for Eurasian Watermilfoil, with multi-season results in documented case studies.
Why a Holistic Stewardship Firm is Finally Offering an Herbicide
For 25 years, CanadianPond.ca has focused exclusively on the holistic management of water quality through improved aeration and beneficial bacteria supplements. We understand why the word “herbicide” makes people nervous; for decades, aquatic chemicals were blunt instruments—short-term fixes that could disrupt the broader ecosystem.
ProcellaCOR FX is a different animal. It isn’t a traditional chemical; it is a molecularly precise bio-mimic that targets a growth protein found in invasive milfoil and a handful of closely related aquatic plants. It is practically non-toxic to amphibians, fish, birds, and mammals. It is applied in minuscule doses and breaks down within days without lingering in the ecosystem. After a quarter-century of water stewardship, we are offering this solution because new technologies have finally provided the surgical, low-dose tool that Québec lakes deserve.

Why More Québec Lake Stewards Are Looking at ProcellaCOR FX
For decades, we fought milfoil with tarps and divers. It was expensive and temporary — a never-ending battle. Some policy-makers and citizens had given up hope of ever finding a way to recover our lakes. ProcellaCOR FX is the first real alternative in 40 years.
Controls Milfoil
ProcellaCOR FX targets the whole plant, roots included.
Significant Savings
Major cost reduction compared to annual diver harvesting or benthic barriers over a 3-year period.
Selective
Designed to target Milfoil specifically and applied surgically to milfoil beds, leaving native pondweeds and lilies to thrive.
No Benthic Disturbance
Does not disturb or isolate the benthic sediments from the water column as tarping does.
A Canadian Precedent: Farlain Lake, Ontario
Canada’s first lake treatment using ProcellaCOR FX took place at Farlain Lake, Ontario, on September 6, 2023. As of now, it remains the only Canadian lake treatment in our current reference base, making Farlain the Canadian case proving its efficacy and safety under real lake conditions.
What Farlain Lake Stewards Are Saying
“We’ve been at it for years and years and years, spending a lot of money, and we’ve been looking for a silver bullet, and I think maybe we found it.”
— Brian Kelso, EWM Committee Lead, Farlain Lake Conservation Association (Ontario)
“We felt like we were beating our heads against a brick wall until Pete discovered ProcellaCOR.”
— Elizabeth Di Chiara, Farlain Lake Conservation Association (Ontario)
“My grandkids are jumping off the dock — no weeds. We love this. It just makes the cottage again.”
— Scott Dales, President, Farlain Lake Conservation Association (Ontario)
The Science: How it Works
Ultra-Low Dose Injection
Applied at parts-per-billion levels—a tiny amount targets only the invasive species.
The “Growth Overdose”
The plant interprets the formula as a growth hormone. It grows so fast that its cellular structure collapses, roots included.
Rapid Breakdown, No Season-to-Season Carryover
Breaks down rapidly in water through sunlight and microbial action, with no meaningful carryover to following growing seasons.
A Clear Choice for Your Lake, Your Family, and Your Neighbours
No Swimming Restrictions
No label restrictions on swimming or fishing.
Concerned about Drinking Water?
No label restrictions on drinking water use.
Native Plants Thrive
“The native plants that we sampled were robust. They were healthy. It succeeded in killing Eurasian watermilfoil without harming native plants.”
— Peter Andrews, FLCA
Fish Populations Healthy
At Farlain Lake, Ontario, walleye population near carrying capacity post-treatment. Fish life “abundant” in all treated areas.
Traditional Methods vs. ProcellaCOR FX
| Feature | Divers/Tarping | ProcellaCOR FX |
|---|---|---|
| 3-Year Cost (per hectare) | $150,000 – $250,000 | $20,000 – $30,000† |
| Duration of Control | 1 Season (Regrowth expected) | Less Than 50% Recovery Within 3 Years* |
| Root Kill | Incomplete (recolonization possible) | Systemic – targets the root crown |
| Fragmentation Risk | Variable (Manual disturbance) | Zero |
*Commercial guarantee: less than 50% recovery within three years. Full guarantee terms apply.
†Estimated cost range. Actual pricing depends on survey requirements, distribution and density of milfoil beds, accessibility, and site conditions.
