ProcellaCOR®

ProcellaCOR® is a next-generation aquatic herbicide designed to control invasive aquatic weeds that repeatedly return year after year. Using a new mechanism of action and a new active ingredient, ProcellaCOR delivers fast, targeted spot treatments with long-lasting results.

For lake managers, pond owners, and aquatic professionals tired of repeated treatments with limited results, ProcellaCOR offers a smarter, more sustainable solution for aquatic weed management.

The Benefits of Using ProcellaCOR

ProcellaCOR^® isn’t just another treatment for aquatic weeds.
It does something different. Researchers have described it as having the best features of other technologies combined.

These are the most significant features that make ProcellaCOR unique:

• ProcellaCOR is selective. It won’t hurt desirable native plants.
• It lasts longer. Forget multiple follow-up visits to keep your water free of Milfoil, Hydrilla, Crested Floating Heart, and others. ProcellaCOR will keep them at bay for much longer than other solutions.
• Reduced Risk. Safety is important to us. To you. To your kids. And our development of ProcellaCOR was no different. Keep enjoying your lake or pond for swimming, fishing, boating, and all the other things you enjoy and love about it.
• It reduces your chemical usage through longer control and less product required for treatment. (Fewer chemicals also means cost savings, an added bonus).

Sustainable Aquatic Weed Management

Most lakes and ponds rely on repeated herbicide applications to manage nuisance aquatic weeds. ProcellaCOR breaks that cycle.

By delivering longer control with significantly less active ingredient, ProcellaCOR supports responsible water stewardship while protecting non-target plants, fish habitat, and overall aquatic ecosystem health.

ProcellaCOR vs. Milfoil

What is Milfoil?

• Watermilfoils are rooted, submersed freshwater aquatic plants in the genus Myriophyllum. There are about 69 known species.
• They’re recognizable by their long, branching, hollow stems and whorled, feather-divided leaves that appear ‘dissected’.

Why is Milfoil a Problem?

• Milfoil spreads easily and grows quickly, crowding out native plants, reducing fish habitats, and reducing wetland habitats for native animals.
• It creates dense mats near the water surface that entangle boat propellers, and make it difficult to swim or fish.

How does Milfoil spread?

• Milfoil is hard to control because it self-fragments - when a piece of the plant breaks off, it re-roots and creates an entirely new plant.
• Milfoil spreads mainly through vegetation reproduction when pulled by a boat propeller, fishing gear, or person/animal.

Aquatic Control

ProcellaCOR vs. Hydrilla

What is Hydrilla?

• The plant is rooted and is distinguishable by long stems the branch and float at the surface, forming thick mats. The stems are covered in whorls of small, serrated leaves.
• Hydrilla (Hydrilla verticillata) is a submersed perennial herb that was originally imported and sold as an aquarium plant in the 1950s.

Why is Hydrilla a problem?

• Hydrilla hurts the natural ecosystem; it alters the water’s pH level, restricts sunlight for native plant growth, removes nutrients for native animals, and removes needed oxygen for fish.
• Hydrilla is one of the most invasive weeds in the world, and it is capable of clogging waterways, and even public water supplies.

How does Hydrilla spread?

• Hydrilla is extremely durable, even out of water. Boats that come in contact with the plant, and don’t get cleaned off, introduce the weed at the proceeding waterbody.
• Hydrilla spreads mainly through stem fragments. Pieces break off when pulled by a boat or trailer, and form entirely new plants wherever they land.

ProcellaCOR vs. Crested Floating Heart

What is Crested Floating Heart?

• Crested floating heart (Nymphoides Hydrophylla) is a freshwater floating perennial that roots in the substrate of water 2'-10' deep.
• The plant leaf looks like a giant heart, with a small, white, rising from the center. It’s commonly used as decoration in garden ponds.

Why is Crested Floating Heart a Problem?

• The plant is extremely durable, having a thick cuticle that makes chemical control via surface application difficult, and being able to spread through numerous methods.
• It rapidly colonizes, and forms mats that block out sun and use oxygen, removing vital nutrients for native plant species and fish.

How does Crested Floating Heart spread?

• Crested floating heart reproduces a number of ways: self-fragmenting (creating new plants from pieces broken off), tubers, roots/daughter plants, and rhizomes.
• The plant is still being sold in nurseries, is leaked into the water supply, and is transferred via unclean boats.
