Nice photo Balkar ji.  English we call it Water hyacinth.  This water plant is a dangerous weed which grows very quickly and difficult to remove once established.  It also depletes the oxygen in the water endagering the fishes and other animals  in the water body.

Regards,
Mani.

Balkarji, I think the first photo is not of Water hyacinth.  Please give the ID of this plant.
Regards,
Mani.

Yes, it is dangerous weed. It infested the Kharun river near my city. Please see the degree of infestation.

But living with this obnoxious weed the Traditional Healers have developed its new uses. Here is interesting document

Traditional medicinal knowledge about a noxious weed, jal kumbhi (Eichhornia crassipes), in Chhattisgarh (India)

There are some bio control agents to remove this Eichhornia. Some
insects that feed exclusively on these plants. Read somewhere long
back.

Neochetina bruchii and other Neochetina are effective but in laboratory conditions only. Few years back the weed researchers declared that Parthenium can manage Water Hyacinth but later common people relaized that it was of academic interest only. The concerned researchers applied Parthenium extract on Water Hyacinth growing in small tub. It is not found feasible to apply Parthenium in bulk to manage this weed in ponds. Hence, after publishing the paper in reputed journal and receiving the award the researchers Never tried to move forward.

In Kharun river it was very easy to use the mechanical control measure as two sides were parallel. In this measure two tractors are run in both sides of river and between them chain is kept across the river. It removes Water Hyacinth within few hours. But due to lack of political will,  BJP and Congress continued fighting over this issue and finally flood in rainy season washed the issue i.e. Water Hyacinth.

By the way please see this website selling furnitures prepared from Water Hyacinth.
