Restore cleaner, healthier water with Cutrine®-Plus Aquatic Herbicide, a professional-grade treatment formulated to control troublesome algae and select aquatic plants in ponds, lakes, reservoirs, and slow-moving waterways. Its fast-acting formula targets nuisance growth before it overwhelms your pond, helping improve water clarity, appearance, and overall aquatic health.

By disrupting essential cellular processes within targeted algae and aquatic plants, it delivers rapid control while supporting a balanced pond management program when used according to label directions.

Ideal for residential ponds, golf course water features, fisheries, irrigation ponds, and recreational lakes, Cutrine®-Plus helps maintain attractive, usable water throughout the growing season.

Best Applications

Ideal For

• Filamentous algae
• Surface algae mats
• Planktonic and other labeled algae species

• Ponds, lakes, decorative water features, and irrigation ponds

Not Recommended For

• Treating an entire pond with heavy algae growth in a single application
• Applications that do not follow label directions or applicable water-use restrictions

How It Works

Cutrine®-Plus works by disrupting essential cellular functions within susceptible algae and labeled aquatic plants. After application, treated growth begins to decline, helping restore clearer water and improve the overall appearance of the pond.

When treating heavy algae infestations, apply to one-third to one-half of the affected area at a time. Staged treatments help reduce the risk of oxygen depletion caused by decomposing algae, protecting fish and other aquatic life.

Always read and follow the product label for approved aquatic uses, application rates, target species, water-use restrictions, and safety precautions.
