Cutrine-Plus Granular 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. Cutrine-Plus is hard water stable. Far less corrosive than other common algaecides.
Begins to work immediately on contact to break down algaes 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 Granular you need for season long control. Early 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 Granular to conveniently spot treat sections of a pond or lake front.
Cutrine-Plus Granular will deliver a layer or blanket of Cutrine-Plus 2 to 3 feet thick over the area treated. Cat litter-size granules quickly settle through water onto algae. Easily control early season bottom growth of Chara and Filamentous Algae. Granules settling on floating mats of Filamentous Algae will control surface growth to a depth of 2 to 3 feet.
Cutrine-Plus Granular is ideal for treating bottom-growing algae such as Chara. Treat Chara in spring and summer when weed is soft and supple. Mature Chara will become calcified or lime-encrusted (gritty) in hard water. Calcified Chara is very difficult to control. Treat early. A single, early season application of Cutrine-Plus Granular will usually control Chara for the entire season.
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 Granular, determine the area to be treated in acres. Use 30 lbs. of Cutrine-Plus Granular per 0.5 acre. Broadcast granules uniformly over treatment area.
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 untreated sections.
