Control of Water Hyacinth in the St. Johns River, Putnam County, Florida,
Abstract
The aquatic plant control plan as proposed calls for the control and progressive eradication of the water hyacinth and other water weeds from the St. John's River, using the herbicide 2-4-D. Over the years, the water hyacinth has clogged the St. Johns River to the point that it is a hazard to navigation and recreational activities. Mechanical harvesting proved to be largely ineffective, and biological controls are not adequately developed. Therefore, the use of herbicides was the logical control method. The herbicide 2-4-D has proved to be a very effective control agent. However, it had been prohibited from use in any free-flowing waters. The Department of the Army, Office of the Chief of Engineers, submitted a petition to the EPA requesting that 2-4-D be approved for use in the St. John's River. After a series of studies indicated that the herbicide 2-4-D did not have adverse environmental effects, the EPA approved a registration for this use. (Author)
