The Niue Department of Agriculture, Forestry and
Fisheries, implemented an eradication programme of
the weed Sphagneticola trilobata commonly known as wedelia. Surveys conducted between 27 February and 8 March showed that wedelia was
found at 35 sites. The total coverage of the weed was estimated at 1 hectare (10,000 sq. m.). The
area of the infestation varied between a few to 1000 sq.m.
The campaign was started in March 2001. Trial applications of the systemic herbicide Round Up (a.i. glyphosate; at 10ml/l) by knapsack sprayer were carried out on identified sites.
Simultaneously, public awareness was raised through a TV interview (both in
English and translated into Niuean), and by designing and placing signboards
at strategically located wedelia infested sites around the island.
The effectiveness of the
herbicide Round Up in controlling dense areas of the weed was found to be
unsatisfactory, and the use of Gramoxone (a.i. paraquat) was advised to
rapidly kill foliage and make underlying stems and shoots more accessible to
following applications of Round Up.

摘要： A study on the use of a screening system to assess proposed plant introductions to Hawaii or other Pacific Islands and to identify high-risk species used in horticulture and forestry which would greatly reduce future pest-plant problems and allow entry of most nonpests.

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.

摘要： This paper is a preliminary account of the status in the Pacific Islands of Wedelia trilobata (L.) Hitch., a recently introduced ornamental groundcover plant that has become an extremely invasive weed in many areas, and has the potential to become one of the most environmentally destructive weeds of the Pacific Islands. It is suggested that Wedelia trilobata should be immediately declared a serious noxious weed, should be restricted from introduction into new islands and habitats, and, where possible, should be exterminated from islands and habitats where it has not gained a foothold.
The paper describes Wedelia trilobata and discusses what is known about its introduction and spread in some island countries, the habitats in which it thrives and has become naturalized or invasive, and the present and potential threat that it poses to island ecosystems and indigenous species. Actions are suggested that could be taken to control the introduction and spread of Wedelia trilobata to islands and habitats where it does not yet exist, and to eradicate it from areas where it is not yet out of control.
