If you have a lake or pond that needs duckweed control, below find some useful tips to kill them.

1. Prevention Is Better Than Cure! Take Preventive Measures to Prevent Lake Weed Growth: If the banks of the pond are steeply sloped, weeds will face hurdles in their growth. However, if the banks have shallow margins, they may grow and eventually they can spread to deep waters. Thus, the ideal height of the bank should be 4 feet where the water’s depth is just 2-3 feet. This can prevent weed from growing.

You can successfully treat 25%-33% of pond area with herbicides at any given time. Too much chemical may harm the species in water

5. Use a Benthic Barrier: Benthic barrier is also popularly known as bottom screen. It covers the sediment like a blanket and compresses aquatic plants by preventing the sunlight to enter. Because in the sunlight, they thrive and when you will cut off their main source, they will eventually die. Colonies that are too extensive to be hand pulled, can be covered with bottom screens.
