Controlling Watermilfoil In Your Lake Or Pond
Physical Management of Watermilfoil
Watermilfoil has a root system which means the roots need to be destroyed to prevent the plant from coming back.

Automated Control of Watermilfoil
For homeowners, automated control of Watermilfoil is ideal when your lake bottom has been cleared and you want to keep it that way without having to continuously labor away cutting weeds.
For lake and pond management companies, automated control of Watermilfoil is ideal when you have a large lake or pond that has been overtaken by the weed.

The Eco Harvester can operate in as little as 12 inches of water and is built so it only takes one person to operate. Additionally, our patent protected Eco Harvester is one-third the price of traditional harvesters, making it one of the most affordable Watermilfoil removal machines on the market.
Herbicide Control of Watermilfoil
Herbicide control is a great option for Watermilfoil because you can literally apply the herbicide and then sit back and let it do its work. Most herbicides can control Watermilfoil throughout the season and only needs to be applied once a year.
Herbicide Products To Control Watermilfoil
Navigate Granular is formulated on special heat treated attaclay granules that resist rapid decomposition in water. They quickly sink to your lake or pond bottom and release 2,4-D into the critical root zone.
Initial effects are indicated by brittle stems and curling leaf tips and are noticeable within 7 to 10 days. A full kill will occur within 3 to 5 weeks.
Hydrothol 191 Granular is highly effective at killing Watermilfoil in the application area and not away from the targeted area. It’s active ingredient is Endothall, mono (N,N-dimethyl alkylamine) salt.
Hydrothol 191 Granular is a slow releasing herbicide which accounts for its long lasting effects. Studies show Hydrothol 191 Granular present in the lake bottom 3 months after its application and had no effect on aquatic life because of the slow release of active chemicals.
