Cygnet - Cutrine Plus


Qty:
  • NOT FOR SALE TO: CA & NY
  • A double-chelated copper solution
  • Effecitve against a wide variety of algal species
  • Best for bottom growing algae such as Chara and Nitella

Cutrine-Plus is one of the most popular algaecides on the market today. It is a double-chelated copper solution effective against a wide variety of algal species. Due to its double-chelate it stays in the water column longer, and in combination with its greater amount of activity in the plant can be much more effective.

This product is a liquid copper-based formulation containing ethanolamine chelating agents to prevent the precipitation of copper with carbonates and bicarbonates in the water. This product effectively controls a broad range of algae including: Planktonic (suspended) forms such as the Cyanobacteria (Microcystis, Anabaena & Aphanizomenon), Green algae (Raphidocelis & Cosmarium) Golden algae (Prymnesium parvum) and diatoms (Navicula & Fragilaria); Filamentous (mat-forming) forms such as the Green Algae (Spirogyra, Cladophora, Ulothrix & Rhizoclonium) and Benthic (bottom-growing) forms such as Chara and Nitella. This product has also been proven effective in controlling the rooted aquatic plant, Hydrilla verticillata.

Waters treated with this product may be used for swimming, fishing, further potable water treatment, livestock watering or irrigating turf, ornamental plants or crops after treatment.

Active Ingredient: Copper Ethanolamine Complex

For use on:

  • Lakes
  • Potable Water Reservoirs
  • Ponds
  • Fish Hatcheries and Raceways
  • Crop and Non-Crop Irrigtion Conveyance Systems (Ditches, Canals and Laterals)

Weeds Controlled

  • Planktonic Algae (suspended) forms such as the Cyanobacteria (Microcystis, Anabaena & Aphanizomenon), Green algae (Raphidocelis & Cosmarium) Golden algae (Prymnesium parvum) and diatoms (Navicula & Fragilaria)
  • Filamentous Algae (mat-forming) forms such as the Green Algae (Spirogyra, Cladophora, Ulothrix & Rhizoclonium)
  • Benthic Algae (bottom-growing) forms such as Chara and Nitella
  • Hydrilla verticillata
  • See label for complete listing of weeds controlled

Application

Surface Spray/Injection Slow-Flowing or Quiescent Water Bodies Algaecide Application: Before applying, dilute the required amount of this product with enough water to ensure even distribution with the type of equipment being used. Typical dilution range is 9:1 when using backpack-type sprayer or up to 50:1 when using water pump equipment or large tank sprayers. Use chart on label to determine application quantity needed per Acre-foot based on algae type and desired PPM needed.
For effective control, proper chemical concentration must be maintained for a minimum of three hours contact time.
Break up floating algae mats manually before spraying or with force of power sprayer if one is used. Use hand or power sprayer adjusted to rain-sized droplets to cover area evenly taking water depth into consideration. If using underwater injection systems such as drop hoses or booms with weighted drop hoses, ensure boat pattern is uniform throughout treatment area. Spray shoreline areas first to avoid trapping fish.
Under conditions of heavy infestation, treat only 1/4 to 1/2 of the water body at a time to avoid fish suffocation caused by oxygen depletion from decaying algae. (see additional Environmental Hazards).

  • Calm and sunny conditions when water temperature is at least 60ºF will usually expedite control results.
  • Effective control of algae requires direct contact with all cells throughout the water column, since these plants do not have vascular systems to transport copper from cell to cell.
  • Visible reduction in algae growth should be observed in 24 to 48 hours following application with full infestation and water temperatures.
  • Re-treat areas if re-growth or new growth begins to appear and seasonal control is desired. Identify new growth to re-check required copper concentration that may be needed for control. Apply treatment along the shore and proceed outwards in bands to allow fish to move into untreated areas.
  • No more than half of the water body may be treated at one time. (refer to Environmental Hazards for additional guidance)
  • The minimum retreatment interval between consecutive treatments is 14 days.

 

Herbicide Application for Hydrilla Conrol Apply mixture at the rate of 5 gallons per surface acre. Dilute with at least 9 parts water and apply as a surface spray or underwater injection.
Control of Hydrilla verticillata can be obtained from copper concentrations of 0.4 to 1.0 ppm resulting from product treatment. Choose the application rate based upon stage and density of Hydrilla growth and respective water depth from the chart on the product label.

See Label for complete application instructions.

Restrictions

Do not use in waters containing Koi and hybrid goldfish. Not intended for use in small volume, garden pond systems

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 hazard, do not treat more than half of the water body to avoid depletion of oxygen due to decaying vegetation.

Wait at least 10 to 14 days between treatments.

This pesticide is toxic to some fish and aquatic invertebrates and may contaminate water through runoff. This product has a potential for runoff for several months or more after application. Poorly draining soils and soils with shallow water tables are more prone to produce runoff that contains this product. Do not contaminate water when disposing of equipment wash-waters or rinsate.

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 organism.

Potable water sources treated with copper products may be used as drinking water only after proper additional potable water treatments.

Trout and other species of fish may be killed at application rates recommended on the label, especially in soft or acidic waters as described above.

See Label for complete restrictions.
