Floating pennywort: Use of liquid nitrogen
Overall effectiveness category Awaiting assessment
Number of studies: 0
Background information and definitions
Liquid nitrogen may provide a tool for localised control of floating pennywort Hydrocotyle ranunculoides when used in combination with other control methods. However, it is reported that some water boards in the Netherlands have tried to eradicate stands of floating pennywort using liquid nitrogen, and have found this to be unsuccessful due to persistence of regenerative plant material below the water surface (Hussner et al. 2012). A description of the treatment and results has not been reported; therefore it has not been possible to confirm these results (Hussner et al. 2012).
