Jalkumbhi, destroyig ponds in north India
Sir, I agree with your comments. This weed has become a nuisance throught the world. But it is ultimately the humans who has propagated it by directly charging untreated waste/water or anything which can be thought off into water bodies/rivers etc. After doing so much of harm to the environment ourselves we cannot blame these natural beings of destroying anything. When humans can lay their hands on anything they desire in the name of development than we should also get an equal competition from the nature also. When human do excesses they should also expect the same, as the law goes “Everything has an equal & opposite reaction”.
Water Hyacinth: this lovely mauve flower of the water hyacinth was spotted today morning while birding in the Kalikapur wetlands of Kolkata.

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.
First photo is not Water hyacinth
First one could be Alysicarpus
Yes, it is dangerous weed. It infested the Kharun river near my city. Please see the degree of infestation.
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.

Thank you for all these info on water hyacinth. I would like to add that though are much publicized as weeds, to some animals they are useful too, a perfect hiding place for waterbirds, water monitor, and maybe a breeding / nesting ground to some, including mosquitoes.
