Find a ProcellaCOR Specialist

ProcellaCOR treats the weeds that keep coming back using a new mechanism and a new active herbicide for fast and long-lasting spot treatment. ProcellaCOR's active ingredient provides long-term control for Hydrilla, Milfoil, Crested Floating Heart, and other tough-to-control aquatic weeds. So you can use less material and get longer control.

If you’re tired of treating and re-treating with limited results, learn more about ProcellaCOR today and get your water back on the right track. Finally.

Stewarding Our Most Precious Resource: Water

Every water body has at least one nuisance weed that keeps coming back year after year. And that means spraying chemicals to control it year after year. Not with ProcellaCOR®. This unique formula requires 40x-100x less active ingredient and achieves significantly longer control. With a Reduced Risk classification from the EPA, it is designed to reduce risk To Our Health, non-target Plants, And Our Water Supply.

Even the EPA says ProcellaCOR is “practically non-toxic” to animals and humans. Plus, it’s applied by the best in the business. Only PRO Certified ProcellaCOR Specialists, highly trained aquatic management professionals, can provide invasive weed management with ProcellaCOR. So You Know It’s Done Right.

Once a specialist sprays ProcellaCOR near the weeds you’ve been dealing with, say goodbye! Those weeds won’t be around much longer to clog your boat propeller, spoil your view, make it unpleasant to swim or fish, etc…longer lasting results.

No one wants repeated applications with the same average results. That’s why SePRO has been hard at work creating a formula that gives you superior control with precision dosing. This new technology is more effective, while protecting wildlife habitat from nuisance weeds.


ProcellaCOR and Milfoil


What is Milfoil?

Watermilfoils are rooted, submersed freshwater aquatic plants in the genus MyriophyllumThere 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.

ProcellaCOR and 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 and 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 spray 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.
