Abstract:  Singhara is known by various names like ‘bull nut’, ‘European water chestnut’, ‘water chestnut’ and ‘water nut’.  T. natans L., an annual plant introduced from Asia, has become abundant in north-eastern United States where it creates a nuisance in lakes, ponds, canals and other slow-moving water bodies. It grows best in shallow, nutrient-rich lakes and rivers and is generally found in waters with a pH range of 6.7 to 8.2. This obnoxious weed out-competes native plants for sunlight and spreads either by the rosettes detaching from their stems and floating to another area, or more often by the nuts being swept by currents or waves to other parts of the water bodies.
