Question

rivers and lakes are filled with water hyacinth. Give precautions

Answer 1

Water hyacinth control is difficult. The most effective methods of control rely on prevention. Make sure to control the nutrient levels in your pond or lake to prevent the rapid and explosive growth. Do not introduce water hyacinth to new ponds unless you are willing to monitor it and take action if its growth gets out of control. It is advised that you only introduce water hyacinth to your own personal ornamental water gardens. Introducing it into natural water bodies is asking for trouble. When harvesting or otherwise removing water hyacinth, do not discard it in a natural water way, instead put it into a compost pile.
