Potential Control of Florida Elodea by Ion-control Agents

Abstract

IT is clear that the problem of excessive vegetation in many lakes, canals and streams in developed countries must be solved if these bodies of water are to continue to be used economically for transportation, recreation and drainage. Submerged weeds such as Florida elodea (Hydrillia verticillata)^1,2 are particularly troublesome because the plant is perennial and usually firmly anchored to the bottom by long adventitious roots; further, it forms dense mats which may clog the top foot of water, and can spread over the water by four different methods.
