District to Treat Aquatic Plants on the Rainbow River

News Release

The "Southwest Florida Water Management District":http://www.swfwmd.state.fl.us/ will be treating hydrilla and water lettuce on the Rainbow River in Marion County during the period of Feb. 2-5.

District workers will apply the aquatic herbicide Aquathol Super K to treat hydrilla on the section of the river downstream of the County Road 484 bridge. The aquatic herbicide Tribune will be applied to scattered infestations of water lettuce throughout the river.

Informational signs will be posted in the treated areas noting treatment dates and applicable water use restrictions.

There will be no restrictions on the use of treated water for swimming, fishing or boating. Established turf and ornamental plants should not be irrigated with treated river water for one day following treatment. Treated river water should not be used as potable water or for irrigating food crops, annual nursery or green house crops including hydroponics and newly seeded or transplanted annual crops, newly seeded or transplanted ornamentals, and newly sodded or seeded turf for seven days following treatment. Water use restrictions do not apply to well or tap water.

Hydrilla is a troublesome aquatic plant from Southeast Asia, which escaped into Florida waters during the late 1950s. It is a fast-growing plant that expands quickly. If it is not controlled, native plant populations, recreational activities, navigation, flood control and fish and wildlife habitat can be negatively impacted.

The management of invasive aquatic plant species on the Rainbow River is a cooperative effort between the District, the Florida Fish and Wildlife Conservation Commission and the Florida Department of Environmental Protection.
