Organism type: shrub
Abrus precatorius a legume, is a nitrogen fixer and where present in large stands can alter soil nutrient status. It is also suspected to have allelopathic effects that could alter native species recruitment.
agricultural areas, natural forests, range/grasslands, ruderal/disturbed, scrub/shrublands
Abrus precatorius seeds are used as beads; A. precatorius is used in folk medicine (USDA-ARS, 2010).
Native range: Africa; temperate and tropical Asia; Australasia; Pacific (USDA-ARS, 2010)
Known introduced range: naturalized in the Neotropics (USDA-ARS, 2010).
Local dispersal methods
Consumption/excretion: Seed, spread by birds.
Physical: Small plants can be dug and pulled out (Motooka et al., 2003).
Chemical: Abrus precatorius is probably sensitive to foliar sprays of triclopyr; good control has been observed with triclopyr ester at 10% in oil applied to basal bark or cut surface and with triclopyr amine at 50% in water applied to cut surface (Motooka et al., 2003).
A user guide developed by Kline and Duquesnel (1996) based on the experiences of practitioners involved in the control of exotic species recommends the following treatment for the control of
- Method: Basal; Herbicide: Garlon 4; Concentration: 10%; Effectiveness: Good;
- Method: Cut; Herbicide: Garlon 4; Concentration: 10%; Effectiveness: Good;
- Method: Cut; Herbicide: Garlon 3A; Concentration: 50%; Effectiveness: Good
