Hydrothol 191 Granular is highly effective at killingHydrilla in the application area and not away from the targeted area. A non-selective weed killer, such as Roundup, is a great option for killing weeds and grass permanently. While sunlight promotes hydrilla growth in water, removing the water will dry it out. Biological control refers to the purposeful introduction of natural enemies (i.e., insects, fish, or diseases) by scientists and environmental managers as a means to weaken and suppress invading plants.

Fluridone is a selective systemic herbicide that has been used to control invasive plants, including hydrilla in lakes in New York and in other parts of the United States. For example, hydrilla is managed on many public lakes to maintain navigation and flood control and to enhance native emergent and submersed plants (such as pondweed and eelgrass).
