Abstract : Waterhyacinth (Eichhornia crassipes (Marl.) Soims), an introduced floating aquatic plant, is well established in tropical and subtropical regions of the world. This plant spreads by rapid and aggressive vegetative reproduction of daughter plants to form dense mats of vegetation that can cover thousands of hectares of an infested water body. The dense mats produced by waterhyacinth can effectively block a waterway to navigation, degrade the habitat and water quality of an aquatic ecosystem, provide a breeding ground for mosquitoes, and destroy recreational and fishery usage (Gallagher and HaIler 1990; Madsen, Luu, and Getsinger 1993; Ral and Munshi 1979). In the United States, waterhyacinth has a northern limit on its range due to the plant's inability to withstand low air temperatures (Aurand 1982, Tyndall 1982). In regions where the winters are severe (extended periods of temperatures below 0 0C), waterhyacinth cannot survive. However, in most of the Gulf Coast states and California, waterhyacinth has become established as an aquatic nuisance weed (Aurand 1982, Penfound and Earle 1948, Tyndall 1982).
