Komeen Crystal provides consistent, on-contact, broad-spectrum control of submersed aquatic weeds and bottom algae in a wide variety of application situations, including high turnover and small spot-treatment areas. This concentrated formulation allows for low use rates and improved control of nuisance aquatic weeds in deep water, high flow sites, or for spot treatments along shorelines.

Active Ingredient: Copper Ethylenediamine Complex

For Use In

  • Golf course ponds
  • Recreational lakes
  • Ornamental ponds
  • Potable water reservoirs
  • Fish ponds
  • Fire ponds
  • Industrial ponds


  • Coontail
  • Duckweed
  • Hydrilla
  • Naiad
  • Pondweed
  • Water lettuce


Apply when weeds are actively growing. The most copper sensitive weed species require a minimum of 3-24 HRS of contact with Komeen in order to provide effective control. Less susceptible species may require longer contact time or higher doses. Significant water movement may result in dilution of the treated water and reapplication may be necessary. Susceptible aquatic weeds will generally drop below the surface of the water within 3-14 days after treatment. If this effect if not observed, Komeen may be re-applied after a minimum of 10-14 days after the initial application. Once weeds drop below the surface, it can take up to 6 weeks to realize the full effect of the treatment.

This pesticide is toxic to fish and aquatic invertebrates. Waters treated with this product may be hazardous to aquatic organisms. 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 10-14 days between treatments. Begin treatment along the shore and proceed outwards in bands to allow fish to move into untreated areas.

Applicators can choose from a variety of treatment methods for unmatched convenience.

  • Spray on the surface by boat
  • Spray from the shore
  • Spray from aircraft
  • Apply as invert emulsion
  • Combine with contact herbicides for one-shot algae and week control

See product label for complete application instructions.


Komeen carries no restrictions on how it may be applied or how soon the water may be used after treatment. Water treated with Komeen can be used immediately after treatment for drinking, watering livestock, fishing, swimming and recreation.
