1 of 1 products in this brand
Cutrine® Ultra Algaecide, Herbicide, Cyanobacteriocide is a chelated copper formulation containing an emulsified surfactant/penetrant combination for highly effective control of coarse (thick cell-walled) filamentous algae, mucilaginous (colonial) planktonic algae, Chara and copper-sensitive vascular aquatic plants. This product controls Planktonic (suspended) forms such as the Cyanobacteria (Anabaena, Aphanizomenon, Microcystis, Pseudanabaena, Oscillatoria), Green algae (Pandorina, Volvox, & Eudorina) Golden Algae (Prymnesium parvum) and Diatoms (Achnanthes, Chaetoceros, & Surirella), Filamentous (mat-forming) forms such as Spirogyra, Cladophora, Hydrodictyon, Vaucheria, and Ulothrix, and attached, Benthic (bottom-growing) attached forms such as Chara, Nitella Gleotrichia and Lyngbya. This product has also been proven effective in controlling the rooted aquatic plant, Hydrilla verticillata, Egeria densa and other copper-sensitive species. The ethanolamines in this product prevent the precipitation of copper with carbonates and bicarbonates in the water. Waters treated with this product may be used for swimming, fishing, further potable water treatment, livestock watering or irrigating turf, ornamental plants or crops immediately after treatment. Algaecide/Herbicide/Cyanobacteriocide is ideal for thick-walled filamentous algae, colonial planktonic algae, Chara and copper-sensitive vascular aquatic plants. Has no general water use restrictions at label rates. Active ingredient is 9.0% copper as elemental (copper-ethanolamine) containing an emulsified surfactant/penetrant. Application rate is 0.6 to 3.0 gallons per acre-ft. Product must be diluted prior to use.

Features & Benefits

Superior Advantages
  • Cutrine Ultra is E.P.A. registered for use in drinking water reservoirs, farm fish and industrial ponds, golf course water hazards, lakes, fish hatcheries and raceways, irrigation water conveyance systems such as canals, laterals and ditches.
  • Water from treated lakes, ponds, irrigation systems and golf course water hazards may be used to irrigate turf, fairways, putting greens and ornamental plants.
  • Cutrine Ultra will not plate-out or precipitate under normal storage conditions nor does the copper in Cutrine Ultra precipitate out and become ineffective in alkaline or hard water.
  • Fish can be caught and consumed immediately after Cutrine Plus application and Cutrine Plus has been used successfully in trout ponds which contained cold, hard water.
  • Cutrine Ultra is available in two formulations (liquid and granular) for controlling floating, suspended and bottom-growing types of algae.
  • Cutrine Ultra effectively controls the noxious submersed weed, Hydrilla verticillata, without requiring post-treatment water use restrictions associated with other herbicides.
  • Cutrine Ultra is compatible in tank mixes with the aquatic herbicides Weedtrine®-D, Reward and Aquathol K.

  • Long-sleeve shirt
  • Long pants
  • Socks plus shoes
  • Goggles or face shield and rubber gloves

User Safety Requirements

  • Follow manufacturer’s instructions for cleaning/maintaining PPE.
  • If no such instructions for washables exist, use detergent and hot water.
  • Keep and wash PPE separately from other laundry.
  • Discard clothing and other absorbent material that have been drenched or heavily contaminated with the product’s concentrate.
  • Do not reuse them.

User Safety Instructions

  • Users must wash hands before eating, drinking, chewing gum, using tobacco, or using the toilet.
  • Users must remove clothing/PPE immediately if pesticide gets inside.
  • Then wash thoroughly and put on clean clothing.
  • Users must remove PPE immediately after handling this product.
  • As soon as possible, wash thoroughly and change into clean clothing. Wash outside of gloves before removing.

Environmental Hazards

  • This product may be hazardous to aquatic organisms.
  • This product may be toxic to trout and other species of fish. Fish toxicity is dependent upon the hardness of water. Do not use in water containing trout if the carbonate hardness of water does not exceed 50 ppm. Do not use in waters containing Koi and hybrid goldfish. Not intended for use in small volume, garden pond systems. (For end-use products in containers ≥5 gallons or ≥50 pounds)
  • Do not discharge effluent containing this product into lakes, streams, ponds, estuaries, oceans, or other waters unless in accordance with the requirements of a National Pollutant Discharge Elimination System (NPDES) permit and the permitting authority has been notified in writing prior to discharge.
  • Do not discharge effluent containing this product to sewer systems without previously notifying the local sewage treatment plant authority. For guidance contact your State Water Board or Regional Office of the EPA.
  • Waters treated with this product may be hazardous to aquatic organisms. Treatment of aquatic weeds and algae can result in oxygen loss from decomposition of dead algae and weeds. This oxygen loss can cause fish and invertebrate suffocation.
  • To minimize this hazard, do not treat more than ½ of the water body to avoid depletion of oxygen due to decaying vegetation. Wait at least 10-14 days between treatments. Begin treatment along the shore and proceed outwards in bands to allow fish to move into untreated areas.
  • Consult with the State or local agency with primary responsibility for regulating pesticides before applying to public waters, to determine if a permit is required. Certain water conditions including low pH (≤ 6.5), low dissolved organic carbon (DOC) levels (3.0 mg/L or lower), and “soft” waters (i.e. alkalinity less than 50 mg/L), increases the potential acute toxicity to non-target aquatic organisms.
