Management Information For details on management of this species including physical, chemical and biological control please read our pdf file on management information.          Location Specific Management Information Disney Wilderness Preserve (Osceola County) (United States (USA)) Jenkins et al. (2004) reports that, "the herbicide imazapyr primarily controlled non-native or other native species with the exception of the non-native P. repens (torpedo grass), which was not adversely affected." Disney Wilderness Preserve (Polk County) (United States (USA)) Jenkins et al.

Stage 2. Weed risk assessment. Science for Conservation 185. 30 p.         Summary: This report is the second stage in the development of a Border Control Programme for aquatic plants that have the potential to become ecological weeds in New Zealand. Importers and traders in aquatic plants were surveyed to identify the plant species known or likely to be present in New Zealand. The Aquatic Plant Weed Risk Assessment Model was used to help assess the level of risk posed by these species. The report presents evidence of the various entry pathways and considers the impact that new invasive aquatic weed species may have on vulnerable native aquatic species and communities.
