Cutrine-Plus Liquid with copper ethanolamine complexes is a highly effective algaecide. Controls a broad range of algae in lakes, ponds, fish hatcheries, irrigation canals, and drainage ditches. Effective on Hydrilla when combined with Harvester Liquid. Cutrine-Plus Liquid is hard water stable. Far less corrosive than other common algaecides.
Begins to work immediately on contact to break down algae's cellular structure. Controls Planktonic Algae in 1 to 2 days, Filamentous Algae in 3 to 4 days.
Early treatment when growth first appears will reduce the amount of Cutrine-Plus Liquid you need for season long control. Early season treatment will also reduce the amount of dead growth.
Control will last from several weeks to several months, depending on the type of algae and local conditions. Several applications will typically be required to maintain season long control on Planktonic and Filamentous Algae. Retreat as new growth reappears. Allow 1 to 2 weeks between consecutive treatments.
Heavy, out of control growth may require more than one treatment or physical removal to gain control. Use under conditions of minimal water flow. For best results, apply early on the morning of a calm, sunny day with water temperature of 60 degrees Fahrenheit or warmer. Contact time should be at least 3 hours. Bright sunlight will improve effectiveness.
Use Cutrine-Plus Liquid to economically treat surface algae or the entire volume of a pond.
Cutrine-Plus Liquid is ideal for treating surface growth of Planktonic Algae and floating mats of Filamentous Algae. In ponds with little or no outflow, long term control of several months can be achieved on Filamentous and Planktonic Algae by treating the entire pond volume.
Cutrine-Plus Liquid may be toxic to Trout if carbonate hardness of treated water is less than 50 ppm. Most surface waters exceed this limit and pose no threat. If in doubt, use the Water Hardness Test Strips. Do not use in water containing Koi or hybrid goldfish.
To apply Cutrine-Plus Liquid, determine the volume of water to be treated in acre-ft. For Filamentous and Planktonic Algae, use 1 gallon of Cutrine-Plus Liquid per 1.5 acre-ft of treated water. For Chara, use 2 gallons of Cutrine-Plus Liquid per 1.5 acre-ft. of treated water. Dilute with a minimum of 9 parts water. Spray uniformly over the water surface as a rain of coarse droplets. Contact with Filamentous Algae will be improved by breaking apart heavy surface mats before application.
For Hydrilla, use 2 gallons of Harvester Liquid mixed with 3 gallons of Cutrine-Plus Liquid per 1 acre to be treated. Dilute mixture with a minimum of 9 parts water and apply as a surface spray or by underwater injection. Add Cygnet-Plus Liquid to increase penetration and contact.
Treat heavy infestations in sections of 1/3 to 1/2 of total algae volume to avoid oxygen depletion. Allow 5 to 7 days before continuing to an untreated section.
Water in areas treated with Cutrine-Plus Liquid has no water use restrictions.
