Interim profile, incomplete information
Taxonomic name: Senecio angulatus L.f.
Common names: canary creeper, Cape ivy, climbing groundsel, creeping groundsel, senecione (Italian), séneçon anguleux (French)
Organism type: herb
Creeping groudsel, Senecio angulatus is a prolific vine that has the ability to form thickets of more than 20 mteres that can cover and smother native flora. Native to South Africa it has been introduced as an ornamental plant to several locations. It is reported as being invasive in New Zealand and Australia. The herbicides triclopyr and metsulfuron methyl have been found to be effective against S. angulatus.
agricultural areas, coastland, estuarine habitats, natural forests, planted forests, range/grasslands, riparian zones, ruderal/disturbed, scrub/shrublands, urban areas
Native range: South Africa - Cape Province (USDA-ARS, 2010).
Known introduced range: Australia, New Zealand (USDA-ARS, 2010)
Chemical: In May 1995, a series of trials compared the efficacy of herbicides on Senecio angulatus in Kananook Creek, Victoria Australia. The herbicides used were triclopyr/picloram (Grazon DS, containing triclopyr 300 g L-1 and picloram 100 g L-1), methsulfuron methyl (Brush-off containing 600 g a.i. kg-1) and glyphosate (Roundup containing 360 g a.i. L-1). The herbicides triclopyr and metsulfuron methyl have been found to be effective against S. angulatus. Please follow this link Newton, 1996 for more details on the trials and results.
Physical: Small infestations can be dug out and the plants disposed by bagging them in black plastic bags left to rot in the sun. Slashing, weed-eating, mowing, rotary slashing and grubbing are manual control methods that can be used. These methods usually result in some re-growth. Regular monitoring is recommended to check for re-growth and seedling establishment. Please follow this link Bergin, 2006 for details on the options used to control S. angulatus on sand dune sites (Bergin, 2006)
