Abstract
Aquatic weeds are unwanted plants that reproduce in the water and grow in numbers. The limited growth of aquatic weeds provides some facilities like shelter, shade, and food for many organisms. When they show their excessive growth in the body of water, then the situation becomes tough for the fish and other organisms. They make the waterbody less nutritious by utilising the nutrients. Depletion of oxygen levels is caused by them, which increases the mortality of the organisms. To overcome this scenario, effective management is needed for the control of aquatic weeds. These weeds can be controlled by manual, mechanical, chemical, and biological means. Manpower is applied in the manual method, whereas simple devices with manpower are applied in the mechanical method. On the other hand, chemicals like 2,4-D, paraquat, mineral oils (diesel and kerosene), Sodium arsenite, Simazine, etc. are given to control the weeds.
