Hydrilla is often confused with the native Elodea or the non-native Egeria. Hydrilla has one or more teeth on the underside of the midrib, neither Elodea nor Egeria have these midrib teeth. The teeth make Hydrilla feel rough when drawn through your hand from base to tip. Flowers of Hydrilla are much smaller (1/4 inch in diameter) than Egeria.
Controlling Hydrilla In Your Lake Or Pond
Physical Management of Hydrilla
Hydrilla has a root system which means the roots need to be destroyed to prevent the plant from coming back.

Automated Control of Hydrilla
For homeowners, automated control of Hydrilla 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 Hydrilla is ideal when you have a large lake or pond that has been overtaken by the weed.
Automated Products To Control Hydrilla
Our Lake Groomer is for homeowners who want to maintain a muck free lake bottom. The Lake Groomer uses a rolling action along the bottom of your lake or pond and dislodges any existing Hydrilla and prevents it from growing.
The Lake Groomer comes standard with three – 7 feet roller tubes that can cover a total of 21 feet of lake bottom and comes with a 3 year warranty.
The Aquatic Mower is an electric powered aquatic weed cutter that mounts to your boat and works very efficiently to cut down Hydrilla fast.

For lake and pond management companies, our Eco Harvester pulls Hydrilla up from the roots and harvests them to be reused as mulch or animal feed.
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 Hydrilla removal machines on the market.
Herbicide Control of Hydrilla
Herbicide control is a great option for Hydrilla because you can literally apply the herbicide and then sit back and let it do its work. Most herbicides can control Hydrilla throughout the season and only needs to be applied once a year.
Herbicide Products To Control Hydrilla
Hydrothol 191 Granular is highly effective at killing Hydrilla 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.
