Disadvantages of Blunt Pondweed

The presence of blunt pondweed in a water body rarely has a significant impact, but large growths have the potential to:

  • Obstruct flow of pumps and irrigation systems

  • Restricts water-based recreation

  • Reduce the aesthetic appeal of the water body

treatment
