09 Dec water hyacinth disadvantages
Planting area: basin of the same size as the bathing area (maximum depth 50 cm), which includes purifying plants (water hyacinth, rush…) which role is to clean water and prevent pathogenic organisms from reproducing thanks to their oxygen production. Water hyacinth also reduces biological diversity, impacts native submersed plants, alters immersed plant communities by pushing away and crushing them, and also alter animal communities by blocking access to the water and/or eliminating plants the animals depend on for shelter and nesting. This plant is a problem in many water storage facilities and is very difficult to eradicate once established. In southern states it is even somewhat winter hardy as long as there are few days below 20* which allows for year round de-nitrification. It should never be deliberately discarded to lakes, rivers, streams, or drainage ditches. The water hyacinth, nicknamed the “Nile flower” in Iraq, is an invasive plant native to South America’s Amazon basin that has ravaged ecosystems across the world, from Sri Lanka to Nigeria. Adaptation lasted for seven days. Surprisingly, Water Hyacinth is still used as an ornamental pond plant in some parts of the world . Primkop Dam near Nelspruit had almost 80% coverage by water hyacinth at one stage; now, through chemical control, it has been reduced to small patches. Low winter temperatures have a further negative impact as this kills off large numbers of the insect species used as control agents. Longterm exposure to sub freezing temperature has a detrimental impact to its ability to reproduce. Solms) is a free floating perennial herb of fresh water ecosystems.It is found at the surface of rivers, lakes, canals and ponds and may root in the mud of shallow waters. It is what we now call the common water hyacinth. Disadvantages of water hyacinth:- It creates dense mats of biomass on water surface which are reducing light to submerged vegetation, can cause oxygen depletions and fish kills. Due to the hyacinth's high growth rate, it has been a great challenge to control its invasion and proliferation. By producing a dense canopy at the water surface, this exotic pest plant shades out native submersed plant species and can uproot native emergent species that are important to wildlife.

Water hyacinths have become an environmental problem and caused economic concerns in southern US climates. Access to harbours and docking areas can be seriously hindered by mats of water hyacinth. (Hussein, 1992, Obeid, 1984; He said, “Under chemical methods, herbicides are effective to control water hyacinth but none have been registered in India for use on water bodies.
