Extract

The paper starts with a report on the growing predominance of aquatic weeds of the genus Salvinia in the waterbodies of the world. The various ways in which Salvinia molesta, particularly, causes pollution and depletion water resources are then reviewed, as are the attempts made so far to control and eradicate Salvinia through chemical, biological, and mechanical, means. It is shown not only that these attempts have failed to achieve their purpose but also that there are possibilities of environmental backlashes being caused by the introduction of chemicals or bioagents into the environment. The importance developing environmentally safe methods of utilization Salvinia has been stressed, so that the cost of mechanical removal of the weed can be offset by the profits earned through its utilization.
