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.

Herbicide Products To Control Hydrilla

Hydrothol 191 Granular Aquatic Weed Control-          Hydrothol 191 Granular

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.
