Abstract : Reproduction capability of the obnoxious submersed aquatic plant HYDRILLA has established this aquarium plant as a menace and serious obstruction to navigation and recreation, water movement for irrigation, drainage and control of floods, and safety of human life. The weed was introduced in Florida in 1960 and now infests some 35,000 to 50,000 acres of Florida waters. Its future spread is unpredictable and limited only by water volumes. In an effort to find a solution a successful test was conducted in the lower Withlacoochee River, Florida, using a diquat-copper mix to determine effectiveness, cost, and future potential in moving or turbulent water. The chemical mix proved worthy of future use on selected areas of the problem weed. The cost of treatment is high but its use on hydrilla can be justified in given aquatic sites. (Author)
