Interim profile, incomplete information
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

Summary: 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.
