    Hydrilla is an Eurasian weed that entered the western hemisphere via Florida sometime in the ’s probably through one aquarium dealer who imported live Hydrilla from Sri Lanka. It was subsequently found in a Miami canal, and from there it spread.   An acre of hydrilla that costs $1, to treat chemically would cost $1, to mechanically harvest, the FWC said. But the costs of mechanical harvesting may soon decrease.

    Heavy infestation of hydrilla at Rodman Reservoir (August 2, ). The rapid underwater growth “pushes” a portion of the mat above the water, giving the reservoir a field-like appearance. PEST STATUS OF WEED Hydrilla verticillata (L.f.) Royle (hereafter, referred to as “hydrilla”) (Fig. 1) is a submersed, rooted. Hydrilla has been verified growing in waters of m in depth with expected growth to be in the - m level in the near future due to light pentration [sic] to m in depth and to the sedimentary composition of the lake.

The aquarium trade introduced hydrilla (Hydrilla verticillata) to the United States. There are two types: the dioecious strain imported from India in the s, and the monoecious strain from Korea that appeared several decades later. They are similar in appearance, and both survive winter by.

Hydrilla is highly adaptable, and it thrives in still and flowing waters, including rivers, lakes, ponds, wetlands, streams and wet ditches, as well as in a range of nutrient and light conditions.

The plant grows up to centimetres a day. It has a competitive advantage over many native plants because it begins converting sunlight to energy.Hydrilla (Hydrilla verticillata) Description.
