Milfoil Control

Some exotic species of milfoil are very aggressive, displacing native species. Eurasian milfoil is an exotic invasive submersed perennial. It reproduces both vegetatively and, less commonly, sexually (seeds). Rhizome division, budding and fragmentation are examples of vegetative reproduction. A single piece of fragmented Eurasian milfoil can multiply into 250 million new plants in one year!

Eurasion milfoil can take over a lake in two years. Large masses of Eurasian milfoil can lead to flooding and interfere with fishing, swimming and boating. Eurasian milfoil mats can increase mosquito habitat and decrease oxygen levels.

We recommend using treatments once plants are established but before flowering occurs. RestoreAccess® Ultra and Hydrothol Granular provide excellent control on Milfoil. RestoreAccess® Ultra will also control many other submerged weeds.

Navigate is a very selective granular aquatic herbicide for control of Eurasian water milfoil. No swimming restrictions apply with this EPA approved herbicide.

Our lake rakes, including our mechanical LAKEMAID®, are an excellent mechanical alternative to keep plants from ever starting to grow.

Identifying Milfoil

(Myriophyllum sibiricum and Myriophyllum spicatum)

Watermilfoil (or milfoil) occurs in patches that tend to crowd out all other growth. Feather-like leaves are finely dissected to midrib and whorled around the hollow stem at intervals along the entire length of the plant.

Milfoil stays submerged except for a stalk of tiny flowers, which can extend above the surface. All milfoil species are easily identified as a group because of their distinctive feather-like leaves, but individual species are hard to differentiate from one another. DNA or pigment analysis may be necessary to tell individual milfoil species apart.

Numerous species of milfoil are common throughout the U.S. Worldwide, the genus (myriophyllum) has 45 species in Europe, Asia, India, Japan, North and Central America and North Africa.

Milfoil can winter over in frozen lakes, thrive in warm pond waters, and live in acidic and calcium rich waters, slow moving waters of lakes and ponds and some rivers. Milfoil is found in a variety of sediments, light levels, temperatures, and depths up to 20 feet.

Eurasian Milfoil is an exotic plant, introduced to the U.S. by the aquarium industry. It is rapidly becoming a major nuisance throughout North America. It is capable of rapid dispersion, principally by fragmentation of plant parts. Each fragment is capable of growing roots and developing into a new plant. Eurasian Watermilfoil is quite competitive with native species and may completely dominate a plant community within a few years after introduction. Due to the plant's ability to form dense growth, water use activities may become severely impaired. These plants are of little value to wildlife or fisheries.

For easy milfoil control, we recommend RestoreAccess® Ultra.
