Eurasian Milfoil Control

Eurasian Milfoil (Myriophyllum spicatum)

About:

Eurasian Milfoil originated in Europe and Asia and made its way to the Eastern United States the better part of a century ago. From the 1940's to the 1970's, it made its way West via animals and water fowl, as well as motorized boat via the propellers and trailers, among other transports as well. By the late 1960's and early 1970's, Eurasian Milfoil had made its way all the way to the West coast states.

Eurasian Milfoil typically has 12 to 21 leaflets, whereas Northern Milfoil typically has 5 to 9 leaflets.  It grows in most areas across the United States.

Problem:

Eurasian Milfoil, once introduced to a body of water, tends to spread very quickly.  Only a small fragment of a plant can break off and re-establish its own colony, making it a very invasive lake weed that can be difficult to get under control.

Physical removal of a portion of an infestation can sometimes be worse than doing nothing at all because fragments break off and float to uninhabited areas.  One small piece of Eurasian Milfoil introduced to a lake or pond can fully take hold of the majority of the body of water in as little as 2-3 years.

Due to the early season nature of the growth, as well as the speed at which it propagates, the Eurasian Milfoil often crowds out native plants and can create a big problem for recreational water use such as boating, swimming, and fishing.

Solutions:

There are multiple ways of coping with the Eurasian Milfoil.

  1. Physical removal by divers

  2. Grass Eating Carp

  3. Weevils - a small herbivorous aquatic beetle

  4. Harvesting or Dredging - be sure to remove all remnants of the milfoil

  5. Aquatic Herbicides - Aquacide Pellets, a slow release tablet with 2,4-D
