Manufacturer: SePRO Corporation
  • Rapid sinking granules for targeted delivery to bottom-growing algae.
  • Visible reduction of algae growth 1-2 days.
  • Chelating agents prevent the precipitation of copper with carbonates and bicarbonates in the water for longer activity.
  • Stays active in the water longer than copper sulfate.
  • Ideal for algae in deeper waters or bottom growing algae- use Cutrine® Plus Algaecide (liquid) for algae on the surface or in the water column.
  • Cutrine® Plus Granular Algaecide is effective in controlling a broad range of benthic (bottom-growing) algae including: Chara, Nitella and filamentous forms. The product is also effective in controlling the rooted aquatic plant, Hydrilla verticillata.  The ethanolamines in Cutrine® Plus Granular Algaecide prevent the precipitations of copper with carbonates and bicarbonates in the water.  Water treated with Cutrine® Plus Granular Algaecide may be used for swimming, fishing, drinking water treatment, livestock watering or irrigating turf, ornamental plants or crops following treatment.
  • Apply this product before growth has reached the surface and begun to form mats or canopies.  If this has already ocurred, applications of Cutrine® Plus liquid is recommended.
  • Calm and sunny conditions when water termperature is at least 60ºF will usually expedite control results.
  • Visible reduction in algae growth should be obeserved in 24 - 48 hours following application with full effects of treatments (bleaching and breaking apart of plant material) sometimes taking 7-10 days depending upon algae forms, weather, degree of infestation and water temperatures.
  • Re-treat areas if re-growth begins to appear and seasonal control is desired.
  • Apply treatment along the shore and proceed outwards in bands to allow fish to move into untreated areas. No more than 1/2 of the water body may be treated at one time.  The minimum retreatment interval between consecutive treatments is 14 days.

This pesticide is toxic to fish and aquatic invertebrates.  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 1/2 of the water body to avoid depletion of oxygen due to decaying vegetation.  Wait at least 14 days between treatments.

Begin treatment along the shore and proceed outwards in harnds to allow fish to move into untreated areas.  Consult with the State or local agency with primary responsibility for the regulating pesticides before applying to public waters to determine if a permit is required.  

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 the water does not exceed 50ppm.  Do not use in waters containing Koi and hybrid goldfish.  Not intended for use in small volume, garden pond systems.

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.

For applications in waters destined for use as drinking water, those must receive additional and separate potable water treatment.  Do not apply more than 1.0 ppm as metallic copper in these waters.
