Background information and definitions
Liquid nitrogen may offer a potential control method for localised control of water primrose Ludwigia spp. when used in combination with other control methods. For certain other species however, this has been found not to be feasible. For example, a review on floating pennywort Hydrocotyle ranunculoides in the Netherlands found liquid nitrogen only killed parts of the floating pennywort plant above water, leaving the bulk of material underwater undamaged (Plant Protection Service et al. 2011).
