Literature Review
Competitors (Other methods)
Hand removal
strenuous and slow
does not cover a larger area
deep water is hard to hand pull
Lowering the water level
Kills weeds on the surface
expensive because the town need to build and implement a damn to lower the waterlevel
only lowered in the winter time to freeze the weeds
Suction-dredging
scuba diver required, and they must be trained professionals
Can only completely remove the weeds from a small lake or pond
expensive, because divers need to be hired to use the equipment
Aquatic Weed Harvester Boats
large and difficult to maneuver
requires a trained professional to operate
a company needs to be hired, and this can get expensive
Biological methods, such as grass carp
Releasing new fish/ organisms into environment
Grass carp will eat all the weeds….but they eat anything and everything and will harm the ecosystem.
It takes a year or more to clear weeds this way.
Carp can not eat roots.
Chemical Control
Chemicals are not allowed in certain bodies of water
Requires protective equipment, proper weed identification, correct dose, application at the right temperature (is the water is too cold nothing will happen)
Some chemicals can be harmful for the enviroment
would be difficult for a homeowner to use on their own
The Structure of Eurasian Milfoil
thick canopy that is tightly packed, and prevents other plants from getting sunlight
Creates an odor in the water
spreads via fragmentation, floating, and then re-rooting
has a complex root system that branches into the mud
Cattail rhizomes root systems are interlaced and hard to pull out, might need to be dug out
Problems Caused by Eurasian Milfoil
It is an invasive species, so it ruins the local ecosystem
Impairs lake/pond based businesses like fisherys
“Eurasian milfoil had a significant negative effect on property values; mean reduction in property values was $94,385 USED, ranging from −$92,558 to −$94,670 USD"(Olden).
Hinders recreational waterfront activities
not visually appealing
Competitors (similar devices made for homeowners)

cuts weeds, and creates fragmentation. Get's stuck on rocks
Blade rake
cost: $119.95
short length of pole
used only from shoreline
