Jatropha gossypiifolia (bellyache bush) is a major invasive plant in northern Australia. Previous biocontrol efforts have focused on insects but the Australian Government is now also keen to explore fungal pathogens. As experts, CABI is carrying out safety and efficacy experiments with the rust pathogen Phakopsora arthuriana using a strain originating from Trinidad. Results will help the Australian authorities decide whether this rust is suitable for biocontrol of J. gossypiifolia in Australia.
Many introduced species can have an adverse effect on native biodiversity, especially on a delicate island habitat such as Trinidad and Tobago. Three forest species are being particularly troubling, namely, Tectona grandis (teak), Acacia mangium (brown salwood) and Leucaena leucocephala (white leadtree). So, with funding from the FAO, CABI researched the species to find out how they behave and where they have invaded with a view to controlling them sustainably.
