Spraying of glyphosate into Ulhas river by the authorities to remove the water hyacinth growing in the river has drawn flak from activists. A city-based group has complained to the Maharashtra Pollution Control Board (MPCB) and other relevant authorities, saying that the chemical is poisonous. 

Environmentalist Stalin D, director of NGO Vanashakti, has written a letter to the chief secretary of Maharashtra, MPCB, principal secretary (environment), Thane Collector’s Office, Union ministry of environment and requested them to stop spraying glyphosate in the river. He further said that the group would inform the Supreme Court, which is hearing the Ulhas river case, about the same.
