Necessity of Aquatic Weed Control in TampaPosted 2.8.2016

Aquatic weed control is needed in Tampa ponds, small lakes and water gardens. Management is needed in these waters for plants ranging from single-celled algae to huge rooted plants. With no weed control, these plants growth will become out of control on these waters.


Phytoplankton are plants suspended in water that are single-celled. These are microscopic marine plants, only visible as brownish or green coloration of water. Not always bad, abundant phytoplankton is the green water which can be beneficial when preventing other plants from growing. However, this can be toxic to fish, cause water surface to have blue-green scum, and cause foul odors. Nutrient input needs to be minimized to reduce this type of plant growth.

Control of Submersed, Floating and Emersed Plants

Submersed aquatic plants grow from the bottom of the pond and can grow to the surface very quickly. Once they surface they become unsightly and a nuisance. Controlling submersed aquatic plants can be very challenging even for the experienced aquatic manager.

Floating plants are plants floating on top of the surface of water. Watermeal, duckweed, and giant duckweed are plants that cause the most problems. Duckweed is controlled by diquat, needing frequent applications. Long-term control can be achieved with fluridone for floating plants when proper conditions are met.

Emersed plants root in the bottom of the pond while extending above, or floating upon water’s surface. Several of these plants are important for wetland mitigation and aquascaping. Some important ones include arrowheads, water lilies, soft rush, and bulrushes. Aquascapes enhance landscapes and are eye-catching, however, expense and maintenance required of these are much more than plant-free ponds due to need of management of plants while controlling weeds. Common weeds include alligator weed, pennywort, and torpedo grass. To achieve aquatic weed control in Tampa, Rodeo is used often as an herbicide, applying with precision. To control these plants, it may be necessary to hand remove.

Different Ways for Control of Aquatic Plants

Depending on what you might require with appearance and needs, management of aquatic plants can be done in different ways. Herbicides, triploid grass carp, or both together may be used for their management. When some plants are selectively controlled while others are not, aquatic weed control becomes more challenging.
