Aquatic Weed Control

We work closely with our pond owners to find the pond management solution that best fit their individual needs.


  1. We use a chemical/biological approach to controlling noxious aquatic weeds. Only EPA approved aquatic herbicides/algaecides are used for aquatic weed/algae control. Applicator will follow all pesticide labeling for the application of the pesticide. Water use restrictions, if required, will be discussed with the client prior to the application, and should be followed.
  2. Herbicide application will include a drift-control/sinking additive. Surfactants, if required, will be added to the spray mixture. Applicator will take a 'conservative' approach to the spray application, making sure that no herbicide spray drift will come into contact with lawns, gardens, or ornamental shrubbery. If desirable plants/grasses are next to the shoreline, aquatic weed treatment in those areas will be extremely conservative and aquatic plants/algae next to the shoreline will not be treated.
  3. Water depth in your pond must have a minimum depth of 30 inches and be free of underwater obstacles for my boat/spray equipment to access those areas of the pond for treatment. Turbid waters can reduce the effectiveness of some aquatic herbicides!
  4. Applicator will not be held responsible for any fish kills that may occur regardless of the reason.
  5. Herbicides/algaecides are very effective in controlling most aquatic plant and algae species. Length of weed control is dependent on the weed species being treated and on the herbicide/algaecide that is used. Aquatic plant and algae regrowth can reoccur in ponds since most herbicides and algaecides biodegrade over time. Conditions in the pond (shallow water depths, nutrients, and sunlight) provide an ideal environment for aquatic weed/algae growth.
  6. You can go to Cygnet Enterprises, Inc. on the Internet to view aquatic herbicide/algaecide products, their labels, and MSDS!
