During last years, relatively reduced crop rotation, shallow tillage, inadequate pre-sowing cultivation and use of the same or identical herbicide groups enabled spread and domination of the weed species Ambrosia artemissifolia L., Iva xanthifolia Nutt. and Xanthium strumarium L. In last years Iva...

The status of biocontrol of Chromolaena odorata, a weed of significant agricultural importance in Papua New Guinea, is assessed. Chromolaena is confirmed present in 391 sites in 12 of the 20 provinces of PNG. A collaborative project on the biocontrol of chromolaena involving the PNG National...

Chromolaena odorata (L.) King and Robinson is a native of the tropical Americas and has become a serious invasive weed in the wet/dry tropics of Eastern and Western India. A stem gall fly, Cecidochares connexa (Diptera: Tephritidae) was introduced from Indonesia into India in 2002. A culture of the ...

Once an incursion of a serious weed is detected, it is important to map its potential extent and undertake surveillance as part of early planning for eradication or containment. This paper describes landscape models for seed generation and seed dispersal from wind and water transport. Integrated...

A series of spatially explicit simulations were conducted to examine factors that affect early detection of an invading weed, three-horned bedstraw (Galium tricornutum Dandy), in a paddock and potentially reduce further spread of the weed beyond the paddock in the harvester or as a contaminant of...

Buddleja davidii, (Franch. (Buddlejaceae), butterfly bush or buddleia) is a native of central China that has become a notorious weed in many temperate and Mediterranean regions. In Tasmania, Australia, B. davidii has only been recorded as an incidental naturalised plant, restricted mainly to...

This paper reviews what is known about the biology, distribution and management of Lantana montevidensis (creeping lantana). This information is used to recommend an appropriate legislative response for this species in New South Wales (NSW). Two species of Lantana have naturalised in Australia,...

Over 230 contaminant species or taxonomic groups, including 23 Victorian noxious weeds have been identified on 106 vehicles and items of plant and equipment. Thirty nine percent of the 70 passenger and four-wheel drive vehicles assessed and 25 percent of the 36 items of plant and equipment carry...

Stepwise discriminant function analysis was used to compare the morphological traits of 15 exotic and 35 native herbaceous species occurring within an area of long-grazed grassland on the Northern Tablelands of New South Wales. Exotic graminoids were shorter, had less persistent litter and a...

Invasive plants can be a source of conflict for conservation management. While the detrimental impacts of plant invasions on biodiversity and ecosystem function are well known, in some cases, invasive plants perform important roles in supporting fauna. For example, fleshy-fruited invasive plants...
