Manual: Hand pulling of plants can be effective when the infestation is small and does not yet have extensive roots and rhizome systems. Caution must be used to prevent the spread of root and rhizome fragments which can resprout. Repeated cultivation can also control sheep sorrel as continued removal of top-growth will eventually starve the roots. Manual means, are however, highly labour intensive (USDA Forest Service, 2006; GOERT, 2009).
Chemical: In general control of Rumex acetosella can be achieved with readily available general herbicides such as dicamba or triclopyr. Follow label and country requirements (USDA Forest Service, 2006). Herbicides are most effective when applied to young and actively growing plants. As R. acetosella prefers acidic soils, control can be increased when combined with liming to increase soil pH (GOERT, 2009).
Other: Rumex acetosella infestations may actually increase after grazing or burning, as it survives via rhizomes in the soil or through seeds buried in the soil. These techniques are not recommended (GOERT, 2009).
1. IUCN/SSC Invasive Species Specialist Group (ISSG)., 2010. A Compilation of Information Sources for Conservation Managers.
摘要： This compilation of information sources can be sorted on keywords for example: Baits & Lures, Non Target Species, Eradication, Monitoring, Risk Assessment, Weeds, Herbicides etc. This compilation is at present in Excel format, this will be web-enabled as a searchable database shortly. This version of the database has been developed by the IUCN SSC ISSG as part of an Overseas Territories Environmental Programme funded project XOT603 in partnership with the Cayman Islands Government - Department of Environment. The compilation is a work under progress, the ISSG will manage, maintain and enhance the database with current and newly published information, reports, journal articles etc.
